ccs2 connector

CCS2, also known as Combo 2, is one of the main connector standards for DC fast charging in Europe and many Type 2 markets. For charging station manufacturers, CPOs, fleet operators, distributors, and EV component buyers, understanding CCS2 is not only about recognizing the plug shape. It is about knowing how connector structure, pin layout, AC/DC charging paths, power ratings, cooling methods, compatibility limits, and long-term reliability affect real charging projects.   For public charging sites, fleet depots, and high-power charging systems, CCS2 connector selection depends on more than rated current. Market fit, vehicle compatibility, thermal design, cable handling, locking reliability, certification, and maintenance planning all influence whether a connector or cable assembly is suitable for the project.     What Is a CCS2 Connector? A CCS2 connector is built around a Type 2 AC interface with two additional DC power contacts below it. The upper section provides the Type 2 charging interface, while the lower section adds DC+ and DC- contacts for DC fast charging.   This combined structure allows a CCS2 vehicle inlet to support Type 2 AC charging and CCS2 DC fast charging when the vehicle and charging system are designed for both modes. The same physical inlet can therefore serve different charging scenarios, from AC destination charging to DC fast charging at public charging sites or fleet depots.   CCS2 is widely used in European DC fast-charging infrastructure and in many markets that follow Type 2-based charging standards. Its physical interface is associated with IEC 62196-2 for the Type 2 AC section and IEC 62196-3 for the DC charging section.     CCS2 Connector Structure and Pin Layout The CCS2 connector has two main physical sections. The upper section follows the Type 2 layout and includes contacts used for AC charging, grounding, and control signaling. The lower section contains the two larger DC contacts used for fast charging. This layout separates power delivery from control and safety functions while allowing one vehicle inlet to support different charging modes.   The exact contact population can differ between a full CCS2 vehicle inlet and a CCS2 DC charging plug. In DC fast-charging plugs, AC power contacts may not be populated because high-power DC delivery uses the lower DC+ and DC- contacts.   Pin / Contact Area Function Used in AC Charging Used in DC Charging Practical Note L1 / L2 / L3 AC phase conductors Yes No Used for single-phase or three-phase AC charging, depending on the vehicle and supply. N Neutral conductor Yes No Used in AC charging configurations that require neutral. PE Protective earth Yes Yes Provides the grounding path for charging safety. CP Control pilot Yes Yes Supports signaling between the EV and charger, including charging state and current limits. PP Proximity pilot Yes Yes Detects plug presence and helps identify cable capability. DC+ Positive DC power contact No Yes Carries positive DC power during fast charging. DC- Negative DC power contact No Yes Completes the DC power path during fast charging.   Pin layout is only one part of connector selection. Mechanical stability, contact quality, locking feedback, cable strain relief, and sealing performance also affect charging reliability, especially at public fast-charging sites with frequent plug-in cycles.     How CCS2 Supports AC and DC Charging A CCS2 inlet can support AC charging and DC fast charging through separate power paths within the same combined interface. In AC charging, a Type 2 plug uses the upper section of the inlet. This is common for home charging, workplace charging, destination charging, and other long-dwell parking scenarios.   In DC fast charging, a CCS2 plug delivers high-power energy through the lower DC+ and DC- contacts. DC power is not delivered through the AC phase contacts. The upper section still supports control, proximity, grounding, and safety functions that help confirm connection status, cable capability, and charging readiness.   Physical fit should not be treated as full charging compatibility. A CCS2 inlet may accept both Type 2 AC and CCS2 DC plugs, but the vehicle and charger must support the corresponding charging mode, communication process, and safety logic.     Where CCS2 Is Used CCS2 is the main DC fast-charging connector standard in Europe and is widely used in many markets that follow Type 2-based charging infrastructure. It is also common in parts of Oceania, the Middle East, Africa, and export-oriented charging projects where European charging standards are adopted.   This regional fit matters for charging station manufacturers, distributors, and infrastructure operators. A CCS2 connector may be the right choice for a European highway charging hub, a Middle East public DC charging project, or a fleet depot using vehicles with CCS2 inlets. But it should not be treated as a universal connector for every market.   North America has historically used CCS1 for DC fast charging, while SAE J3400 / NACS is now an important connector path in that market. For global projects, connector selection should follow the target market, vehicle parc, local regulations, certification requirements, and the charging standards used by the vehicles that will actually visit the site.     CCS2 Power Rating: Voltage, Current, and Real Charging Power CCS2 charging power is determined by voltage and current, but the rated number on a connector or charger does not mean every charging session will deliver that power. In simple terms, electrical power is calculated as voltage multiplied by current. For example, a 1000 V and 500 A system represents a theoretical 500 kW electrical ceiling.   In real charging projects, delivered power is usually lower than the theoretical maximum. It depends on the vehicle battery voltage, battery state of charge, charger cabinet output, cable current rating, ambient temperature, and the limits defined by the charging system. A vehicle may accept high power only during part of the charging curve, then reduce current as the battery approaches a higher state of charge.   Among these limits, heat is usually the most important one in high-current CCS2 applications. Contact resistance, cable design, cooling method, and plug-in frequency all affect temperature rise at the connector and cable. If the system approaches its thermal limit, the charger may reduce current to protect the connector, cable, and vehicle inlet. CCS2 selection should therefore reflect the real duty cycle and thermal margin, not only the highest advertised power rating.     Air-Cooled vs Liquid-Cooled CCS2 Connectors Not every CCS2 fast-charging project needs a liquid-cooled connector. The choice should follow the required current level, duty cycle, ambient temperature, charging window, and maintenance capability.   Air-cooled CCS2 connectors are a practical choice for mid-power DC charging, moderate utilization, longer dwell-time parking, and cost-sensitive sites. They are simpler to install and maintain because they do not require coolant circulation, pumps, hoses, or extra cooling-system monitoring. For urban public chargers, retail parking, workplace charging, and some depot projects, air-cooled CCS2 can provide enough performance with lower system complexity.   Liquid-cooled CCS2 connectors are better suited to sustained high-current charging. Typical applications include highway fast-charging hubs, high-utilization public DC sites, fleet depots with short charging windows, hot-climate installations, and projects where derating or high handle temperature would affect uptime and user experience. Liquid cooling improves thermal control under heavier loads, but it also adds cost, system complexity, and maintenance requirements.   The decision is not “air-cooled versus better.” It is whether the site needs sustained high current under real operating conditions. If the project has frequent sessions, short dwell time, high-power vehicles, or high ambient temperature, liquid cooling may be justified. If utilization is moderate and cost control matters, air-cooled CCS2 may be the better fit.     CCS2 Connector Options for Different Charging Needs   Air-Cooled CCS2 Connector Up to 400A Liquid-Cooled CCS2 Connector Up to 600A     CCS2 Connector Selection Checklist for Charging Projects A CCS2 connector should be selected around the project, not only around the highest current rating. The checklist below helps buyers connect product specifications with real charging conditions, market requirements, and long-term operation.   Selection Point Why It Matters What to Confirm Target market Connector standards vary by region. Confirm whether CCS2 matches the vehicles, infrastructure standard, and regulations in the destination market. Vehicle compatibility The vehicle inlet and charging capability define what can actually be used. Check whether the vehicles support CCS2 DC charging, Type 2 AC charging, or both. Charger power level The connector must match the charger cabinet and expected site use. Confirm charger output, power-sharing logic, and expected daily utilization. Voltage and current rating Power rating depends on both voltage and current, not only the advertised kW number. Confirm voltage range, peak current, continuous current, and thermal limits. Cooling method Thermal design affects derating, handle temperature, and service life. Choose air-cooled or liquid-cooled according to current level, duty cycle, and ambient temperature. Cable length and handling Cable reach, weight, and flexibility affect installation and user experience. Balance parking layout, cable length, bending radius, weight, and handling comfort. Locking and feedback Failed lock confirmation can stop a session before charging begins. Confirm latch design, lock feedback, microswitch logic, and charger-side signal requirements. Sealing and protection Outdoor chargers face rain, dust, UV exposure, and repeated handling. Check IP rating, material durability, strain relief, and environmental suitability. Certification Compliance affects market access and customer acceptance. Confirm required certifications, test reports, and documentation for the target region. Maintenance and spare parts CCS2 connectors are wear parts in high-use sites. Plan inspection intervals, spare connectors, cable replacement, and failure response. Supplier support B2B projects often need more than a standard part number. Confirm customization options, technical support, certification documents, spare parts, and delivery stability.   A CCS2 connector that looks suitable on a datasheet can still fail in the field if the duty cycle, thermal margin, cable handling, or maintenance plan is wrong. Selection should reflect the real charging environment, not only peak current, connector shape, or a standard part number.     CCS2 vs Type 2: What Is the Difference? Type 2 and CCS2 are closely related, but they are not the same connector. The main difference is that Type 2 is an AC charging interface, while CCS2 adds a DC fast-charging path below the Type 2 section.   Item Type 2 CCS2 Main use AC charging AC charging and DC fast charging Connector structure Type 2 interface only Type 2 upper section plus two lower DC contacts DC fast charging Not supported Supported if the vehicle and charger are designed for it Typical applications Home charging, workplace charging, destination charging Public DC charging, highway charging hubs, fleet depots Vehicle inlet Type 2 inlet CCS2 inlet Plug compatibility Uses a Type 2 AC plug Can usually accept a Type 2 AC plug for AC charging and a CCS2 plug for DC charging   The key point for buyers is compatibility. A similar connector shape does not mean the same charging capability. A Type 2-only vehicle cannot use CCS2 DC fast charging unless the vehicle has the required DC charging hardware, communication support, and safety system.       CCS1 vs CCS2: Regional and Design Differences CCS1 and CCS2 are both Combined Charging System connectors, but they are built on different AC connector bases. CCS1 uses the Type 1 / J1772 upper section, while CCS2 uses the Type 2 upper section. Both add two lower DC contacts for DC fast charging.   Item CCS1 CCS2 AC base connector Type 1 / J1772 Type 2 Main region North America and related markets Europe and many Type 2 markets DC fast-charging contacts Two lower DC contacts Two lower DC contacts AC charging support Mainly single-phase AC Single-phase or three-phase AC, depending on the vehicle and supply Typical project use North American DC fast-charging projects European and Type 2-market DC fast-charging projects   For global charger manufacturers, distributors, and charging operators, the choice between CCS1 and CCS2 should follow the destination market and vehicle population. A connector that fits one region’s infrastructure may not match another region’s vehicles, certification requirements, or charging standard expectations.     CCS2 Compatibility Checks Before Selection CCS2 compatibility is not only a question of connector shape. In a charging project, compatibility should be checked across the vehicle, charger, connector, cable assembly, control logic, and certification requirements. A connector may physically match the inlet but still fail to support the required charging mode, locking logic, or safety process.   Before selecting a CCS2 connector or cable assembly, buyers should confirm these points: Compatibility Check Why It Matters Vehicle inlet type Confirms whether the vehicle uses CCS2, Type 2 AC, CCS1, NACS, or another inlet design. Charging mode Separates AC charging, DC fast charging, and combined AC/DC use. A Type 2-only vehicle cannot gain DC fast charging through an adapter. Communication and control DC charging requires the correct communication process, control pilot behavior, proximity detection, and safety validation. Locking and safety validation The charger must confirm that the plug is inserted, locked, and ready before high power is delivered. Certification region CCS2 products used in different Type 2 markets may require different documentation or compliance evidence. Adapter use An adapter should be evaluated as a separate rated product, not as a simple mechanical bridge.   The safest approach is to define compatibility by use case, not by connector name. A public DC charger, a fleet depot charger, an AC destination charger, and an adapter-based charging scenario may all involve Type 2 or CCS2 terminology, but their technical requirements are different. Buyers should provide the target market, vehicle model or inlet type, charger output, expected current, cable length, cooling requirement, and certification needs before finalizing the connector choice.   This prevents a common project mistake: selecting a connector that matches the visible interface but does not match the charging mode, thermal load, control logic, or compliance path required in the field.     Reliability and Maintenance Checks for CCS2 Connectors For public charging sites and fleet depots, CCS2 connector reliability is not only about passing initial tests. The connector is handled every day, exposed to outdoor conditions, and repeatedly used under electrical and mechanical stress. Over time, small changes in contact condition, locking feedback, cable strain, or sealing performance can lead to failed sessions, derating, user complaints, or earlier replacement.   Operators should pay attention to these signals during routine inspection: Check Point Why It Matters What to Watch Contact condition Poor contact quality increases resistance and heat. Discoloration, wear, contamination, abnormal temperature rise. Handle temperature High surface temperature affects safety and user experience. Repeated hot-handle complaints or temperature-related derating. Locking feedback The charger must confirm the connector is properly inserted and locked. Failed lock detection, unstable latch response, session start failure. CP / PP signal stability Control and proximity signals affect connection recognition and charging readiness. Re-plug events, communication errors, unstable charging start. Cable strain relief Cable movement and pulling force can damage the handle and internal connections. Cracks, loose cable entry, excessive bending, damaged sheath. Sealing condition Outdoor connectors face rain, dust, UV, and repeated handling. Damaged seals, water ingress risk, dust buildup, reduced IP performance. Derating frequency Frequent power reduction may indicate thermal or connector-side limitations. Current reduction under normal operating conditions. Coolant condition For liquid-cooled connectors, cooling performance affects high-current stability. Leakage, low coolant level, blocked flow, abnormal pump or sensor alarms.   Maintenance planning should match site utilization. A low-use DC charger may only need periodic visual inspection and cleaning, while a high-traffic highway charger or depot system should track failed sessions, derating records, connector temperature, and replacement cycles. The goal is not only to buy a connector with the right rating, but to keep it stable under the site’s real operating load.     FAQ What is a CCS2 connector? A CCS2 connector, also known as Combo 2, is an EV charging connector that combines a Type 2 AC interface with two additional DC contacts for fast charging. It is widely used in Europe and many Type 2-based markets for public DC charging, fleet charging, and high-power charging projects.   Is CCS2 the same as Type 2? No. Type 2 is mainly an AC charging interface. CCS2 uses the Type 2 upper section and adds two lower DC contacts for DC fast charging. A CCS2 inlet can usually accept a Type 2 AC plug, but a Type 2-only inlet cannot support CCS2 DC fast charging.   What is the CCS2 connector pin layout? A full CCS2 vehicle inlet includes the Type 2 AC contact area, protective earth, control pilot, proximity pilot, and two lower DC contacts. In CCS2 DC charging plugs, the AC power contacts may not always be populated because high-power DC charging uses DC+ and DC- for power delivery.   Can a CCS2 inlet support both AC and DC charging? Yes, if the vehicle and charging system are designed for both modes. AC charging uses the Type 2 section of the inlet, while DC fast charging uses the lower DC contacts. Physical fit alone is not enough; the vehicle must support the required charging mode, communication process, and safety logic.   Do all CCS2 chargers need liquid-cooled connectors? No. Air-cooled CCS2 connectors can be suitable for mid-power DC charging, moderate utilization, longer dwell-time parking, and cost-sensitive sites. Liquid-cooled CCS2 connectors are more suitable for sustained high current, high-utilization sites, hot climates, and projects where derating or handle temperature is a concern.   What should buyers check before choosing a CCS2 connector? Buyers should confirm target market, vehicle compatibility, charger output, voltage and current rating, cooling method, cable length, locking design, IP protection, certification, and maintenance plan. Supplier support, documentation, spare parts, and delivery stability also matter in B2B projects.     Selecting CCS2 Connectors for a Charging Project? Choosing the right CCS2 connector depends on more than plug shape or rated current. Market fit, vehicle compatibility, cooling method, cable design, certification, and maintenance requirements all affect project performance.   Contact Workersbee to discuss CCS2 connector and cable assembly options for public charging sites, fleet depots, charger manufacturing projects, and high-power DC charging systems.

IntroAFIR (Regulation 2023/1804) now sets the floor for publicly accessible EV charging across the EU. For CCS2 DC sites, that means ad-hoc (no-contract) access, clear and comparable pricing, acceptance of widely used payment instruments on higher-power chargers, digital connectivity with smart-charging capability for new or renovated installs, and corridor coverage targets on key roads. The playbook below translates those obligations into actions a site team can run this quarter.     What AFIR changes on the ground for CCS2• In force since 13 April 2024, with binding rules for publicly accessible charging. • DC uses CCS2; AC uses Type 2 in the relevant power classes. • Public DC points must use fixed cables by 14 April 2025; plan holsters, glands, and strain-relief accordingly. • All public points must be digitally connected by 14 October 2024; new points (from April 2024) and qualifying renovations (from October 2024) must be smart-charging capable so operators can manage load, pricing, and availability remotely.     Payments and pricing that pass an AFIR audit• Ad-hoc access: drivers must be able to start and pay without a prior contract or app. • Accepted instruments: for ≥50 kW, new installs must accept widely used payment instruments on the charger (card reader or contactless device that reads payment cards). Existing ≥50 kW on specified roads face a retrofit deadline on 1 January 2027. For chargers under 50 kW, operators can use a secure online payment flow—for example, a QR code that directs the driver to a checkout page. • For ≥50 kW chargers, ad-hoc sessions must be priced by energy delivered (kWh). A per-minute occupancy fee after a short grace period is allowed to deter bay blocking. • Price clarity at <50 kW: present components in a clear order—per kWh first, then per minute, then per session, then any other fees. • Pre-session visibility: show the price before charging begins—on the charger where required, or via clear electronic means where permitted.     Operator tips for fewer abandoned starts• Keep the flow to four steps: select connector → confirm per-kWh price (and any occupancy-fee rule) → pay by card/NFC or scan QR → charging starts. • Make the per-kWh price the largest figure on the screen or price board. • Give a visible grace period (for example, 10 minutes) before any occupancy fee starts. • Test the QR journey on low-signal phones; if it’s slow, drivers will bail.     CCS2 hardware and bay ergonomics• Cable reach and mass: high-power DC cables are thicker and heavier. Use balanced holsters, sensible pull angles, and (where permitted) swivel arms so front, rear, and side inlets can be reached without dragging cables on the ground. • Wet-weather handling: glove-friendly grips and anti-twist boots reduce mis-operations in rain and cold. • Labeling and guidance: put connector label, nominal power, and price highlights at driver eye line; add a simple three-step instruction near the holster. • Accessibility: plan kerb ramps, bay width, handle height, and display angles for wheelchair users and shorter drivers. • Lighting: even, low-glare lighting over holsters and screens reduces errors at night.   Digital connectivity, smart charging, and open data• Remote operations: connected chargers let you push price changes, collect error codes, and restore service faster. • Smart-charging capability: for new or renovated sites, support pool-level load management to control peaks and align with grid contracts. • Open data: operators must publish both static and real-time information—location, status, availability, and pricing—via standardized APIs/formats so national access points and third-party apps can display accurate details. Build API hygiene early to avoid last-minute rework.     TEN-T corridor planning (light-duty)• Spacing and pool size: on the core network, install charging pools roughly every 60 km. By 31 December 2025, a pool should provide at least 400 kW total with at least one 150 kW point; by 31 December 2027, at least 600 kW total with at least two 150 kW points. • Design implications: start with at least one 150 kW bay and scale to multiple high-power bays as targets rise; size upstream capacity with headroom. • Redundancy: use N+1 on dispensers and communications so one failure doesn’t take out the site.     AFIR compliance and UX checklist Item Applies to What to implement Evidence to retain Ad-hoc access (no contract) All public points One-tap card/NFC or secure QR flow Start screen and payment receipt Per-kWh ad-hoc pricing ≥50 kW Energy-based price; optional occupancy fee after grace On-charger price board/screen Price component order <50 kW Show per kWh → per minute → per session → others Display or electronic page Payment instruments on new installs ≥50 kW Card reader or contactless device able to read payment cards Terminal present and functional Retrofit plan where required Existing ≥50 kW on specified roads Dated workplan and purchase orders Project tracker Digital connectivity All public points Telemetry and remote control verified CSMS logs/screens Smart-charging capability New builds / qualifying renovations Load-management profile tested Test script and change logs Fixed DC cable All public DC points Fixed cable and holster per outlet As-built photos/drawings Open data/API feed All public points Static + dynamic data published API spec and update cadence     Mini case: measurable gains from a clearer flowA four-bay, 600 kW site moved from app-first to an ad-hoc flow with on-charger card acceptance and a short, clearly stated grace period before any occupancy fee. Results after eight weeks: higher start-success rate, fewer aborted sessions at the payment step, and shorter post-charge dwell. The same elements that satisfy AFIR—transparent pricing and universal payments—also lift throughput and revenue quality.     Where Workersbee fits Workersbee designs and manufactures EV charging connection products used in public DC and AC environments.

The sites that win drivers go a step further: crystal-clear pricing, fast universal payments, reliable CCS2 cables and holsters, and accurate data that appears wherever drivers plan their trip.   Workersbee’s CCS2 (naturally cooled and liquid-cooled), Type 2 AC, and supporting parts can be specified where they fit the power targets, ergonomics, and maintenance preferences of each site—helping operators meet AFIR requirements while delivering a smooth, predictable experience.

With the explosive growth in demand for electric vehicles, the need for EV charging infrastructure is also increasing rapidly. Especially for long-distance travel, there is a higher demand for DC high-power public chargers in highway corridors. Governments are making efforts to advance the construction of high-power charging stations，but the progress has been less than ideal due to the immense financial pressure, high initial costs, and various requirements for government incentives. The market needs a shot in the arm with high-performance and more cost-effective fast-charging product. Workersbee's natural-cooling CCS2 charging connector 1.1 is entering the market with full attention.   The CCS2 charging connector 1.1, is another exploration by the world-renowned charging solutions provider Workersbee in the EV charging revolution. Apply natural-cooling technology to support STABLE CONTINUOUS current output up to 375A, setting a new standard for natural-cooling performance in high-power DC charging. Apart from the improvement in charging efficiency, it has also made breakthroughs in technological innovation, once again leading the charging market in terms of reliability, safety, cost-effectiveness, and market applications.   The temperature rise generated by conductor resistance is a critical factor in the thermal losses of charging energy. To overcome this stubborn problem, product engineers use terminal ultrasonic welding technology to replace traditional riveting technology to reduce the resistance at the terminal connection, consequently lowering the temperature rise and ensuring that each component of the equipment works properly within the allowable temperature range.     With the support of natural-cooling technology, the charging connector can maintain a lower temperature rise range even during high-power charging, reducing the risk of overheating during charging sessions and allowing for a greater current to pass. What we can be confident about is that it can continuously charge at a high current of 375A. Through multi-sample laboratory testing, even if charged at a peak of 400A for about 60 minutes, the terminal temperature rise is still controlled within 50K in safety. The outstanding charging capability enables electric vehicles to gain more energy in a short time, providing EV owners with a more efficient charging experience. It also significantly enhances charging safety, ensuring the long-term stable operation of chargers.   Internally, the shell of the connector adopts the modular design makes it an efficiently producible standard component, further reducing component costs. The clever multiple-seal structure enhances the waterproof performance at the connector-cable junction, making it easy to achieve an IP55 protection level. It is not only waterproof and dustproof, but also moisture-proof, which is very reliable in humid environments in some areas.     It effectively prevents water vapor from penetrating the charging plug, avoiding potential short circuits and leakage accidents. Whether in harsh weather conditions with rain or snow or high-humidity environments, it offers a reliable protective barrier, ensuring that the charger remains in an efficient, stable, and safe working state.   Additionally, it boasts a series of powerful safety protection measures. The material selection for product manufacturing is also rigorous, requiring materials to possess high flame resistance, pressure resistance, wear resistance, impact resistance, and high oil resistance. Such excellence in R&D and production requirements prompts us to provide more reliable charging solutions for charging stations, while also extending the service life of charging connectors and cables, meeting user demands for high standards and high-quality products, and reducing maintenance costs.   Compared to AC charging stations, DC charging stations have higher charging efficiency and are more favored by car owners who need rapid recharge on highways. Compared to liquid-cooling systems, the CCS2 natural-cooling charging connector has a clear advantage in cost-effectiveness. Its high compatibility with natural-cooling charging stations reduces the complex and expensive building costs of liquid cooling systems, cable investment costs, and operational maintenance costs, making fast charging more economically feasible and contributing to the widespread adoption of CCS2 connectors and even electric vehicles.   Workersbee's CCS2 natural-cooling connector 1.1 has not only achieved significant technological breakthroughs but has also demonstrated strong competitiveness in the market.
