North American models are shifting to NACS (SAE J3400), while much of Europe stays with CCS2 for the foreseeable future. Public networks are also changing: many CCS sites advertise 350 kW ports, and newer V4 Superchargers in North America can deliver higher peak power than the older V3 sites.   For fleets, site owners, and procurement teams, the decision is less about “which logo wins” and more about: fit with region, adapter and access timelines, and how your vehicles and thermal design turn rated kilowatts into real session speed.     At a glance: connector families Aspect NACS (SAE J3400) CCS1 (North America legacy) CCS2 (Europe default) AC/DC in one plug Yes (shared pins) DC uses the Combo add-on below J1772 DC uses the Combo add-on below Type 2 Typical public DC today* Up to ~325 kW at many V4 sites in NA Up to ~150–350 kW depending on site Up to ~350 kW at many EU sites Voltage window (typical) 500–1000 V variants exist; vehicle limits apply Often up to 1000 V Often up to 1000 V Current limit in spec No fixed ceiling; thermal limits govern practical power Defined by station/vehicle/cable ratings Defined by station/vehicle/cable ratings Cable/handle feel Compact head; lighter feel at comparable current Larger head than NACS Larger than NACS; mature ecosystem in EU Region default North America is transitioning to NACS Being phased out on new NA models Europe remains CCS2 for cars Adapter & access Adapters bridge older CCS1 cars; non-Tesla access is station/adapter dependent Increasingly needs adapter to use NACS sites Adapters exist for some use cases; country policies vary *Real charging speed always depends on vehicle voltage architecture, temperature, state of charge, and site load sharing.     What changes performance in the real world Vehicle architecture. 800-V vehicles can take advantage of higher site voltage; 400-V platforms often cap around 250 kW even at bigger posts.   Thermal path. Cable cooling, pin and cable temperature sensing, and station derating logic decide whether peak power holds or tapers early.   Station design. Power sharing between stalls, cabinet topology, and firmware make two “350 kW” posts behave very differently under queue pressure.       Two common scenarios North America (mixed network, rapid NACS adoption)New models increasingly ship with a NACS inlet. Owners of recent CCS1 vehicles often use an OEM adapter for Supercharger access, but availability and supported sites are still rolling out brand by brand. Many non-Tesla vehicles also continue to use CCS posts on open networks, which can be competitive for session speed when the site is healthy and the car can hold current.   Europe (CCS2 remains the baseline)Passenger cars will remain CCS2 for the medium term. Networks and vehicles are mature around CCS2, with broad support for high-power cabinets. NACS appears mainly in NA-market imports and pilot installs; for business planning in the EU, CCS2 is still the practical default for cars. (Heavy-duty platforms are a separate discussion as MCS rolls out.)   Reliability and user experienceConnector geometry is only part of the story. What most drivers feel is site uptime, payment flow, cable reach, and how fast the car gets back on the road. The networks that win on “it just works” optimize maintenance, software, and the thermal path as much as headline power.   Hardware planning (for operators and OEMs)If your site mix serves different vehicle generations, consider pairing a Workersbee NACS DC plug for compact ergonomics with a Workersbee CCS2 liquid-cooled handle where higher sustained current is the goal. This lets you match region and vehicle mix without forcing a single compromise. Use replaceable wear parts, accessible sensors, and clear torque specs to keep swap time down in the field.     Where “1 MW” fitsMegawatt-class charging belongs to specific use cases and future connector evolutions. Today’s light-duty passenger sessions are more often bounded by vehicle limits and thermal design than by connector headline numbers. Focus procurement on sustained current capability and temperature rise under your climate and duty cycle.     Choosing for your use case You mostly operate in North America, with newer models arriving: Choose NACS for new installs or mixed posts where feasible. Keep some CCS1 coverage during the transition, or provide adapters with clear driver guidance.   You operate in Europe for passenger cars: CCS2 remains the lowest-friction choice. Add NACS only for defined fleets that require it.   Your KPI is queue time and revenue predictability: Prioritize hardware that can hold current without early thermal roll-off, plus cables that drivers can reach and plug at natural angles. Field-service features matter as much as peak numbers.     FAQ Do I need an adapter in 2025?If your car has a CCS1 inlet and you’re in North America, your brand may offer a CCS-to-NACS DC adapter for select Supercharger sites. Newer models with a native NACS inlet won’t need an adapter at those sites. Check your automaker’s specific support window and station compatibility.   Will Europe switch to NACS soon?Not in the near term for passenger cars. CCS2 remains the de facto standard, with strong network coverage and vehicle support. Multi-standard sites exist, but CCS2 will stay central for EU planning.   Why does one “350 kW” site feel faster than another?That label is a capability, not a guarantee. Vehicle voltage window, the station’s power-sharing strategy, ambient temperature, and the cable’s thermal performance all decide how much current your car can hold after the first few minutes.   Is “325 kW” the new normal for Superchargers?Newer V4 sites in North America can deliver higher peak power than V3, and some vehicles can take advantage of it. Many cars will still top out around 250 kW due to vehicle limits, and session averages depend on temperature and state of charge.   What should I ask suppliers before I buy?Ask for temperature-rise data at the handle under sustained current, sensor access and diagnostics, documented torque steps, and swap time for seals and wear parts. For mixed networks, confirm adapter support and cable reach for your parking layouts.     A simple way to land this decisionPick the connector family that fits your region and fleet. Then close the gap with a short, repeatable site trial in your climate. If you want parts that shorten swap time and keep bays open, look for replaceable seals, accessible triggers, and clearly documented torque values—areas where Workersbee CCS2 liquid-cooled handles and Workersbee NACS DC plugs are designed to help service teams move fast.

As the number of electric vehicles on the road continues to increase, the demand for EV Charging Infrastructure has also reached an unprecedented level. Low-power slow chargers take a long time to fully charge EVs, limiting the charging experience for vehicle owners, especially for drivers who need to travel long distances. High-power chargers significantly improve charging efficiency, reduce charging time, and enhance the market competitiveness of electric vehicles for long journeys. However, the high heat generated by high-power charging cannot be ignored, as it not only affects charging efficiency but also relates to Electrical Safety. Efficient Liquid Cooling technology has emerged as a solution.   This article will briefly discuss how liquid cooling technology serves high-power charging for EVs, the classification of liquid-cooled charging connectors, and the benefits for businesses.   What is Liquid Cooling? We know that conductors all have resistance and will generate heat due to the thermal effect of current. Under a 250A current, the temperature rise of an ordinary 80 square DC charging plug is about 40K.   As the charging current increases, the heat generated by the current also becomes more significant. To keep charging safe, we must ensure that the temperature of the charging connector terminals and cables is within an appropriate range.   Although increasing the conductor cross-sectional area can solve this problem, it will also increase the weight of the cable and make it more difficult to operate. However, using liquid-cooled high-power charging technology, the Cooling Efficiency is higher, and the weight of the charging cable is lighter.   Liquid-cooled charging uses a liquid cooling medium to circulate under the propulsion of a power pump, carrying away the heat generated by the cable and charging connector, and reducing the temperature at the hot components, allowing the charging plug to withstand a larger current.   The cooling medium is divided into oil cooling and water cooling. Oil cooling is usually immersion cooling, with the medium being dimethyl silicone oil or E4 CCF, which have very high heat exchange efficiency. The water cooling medium is water plus ethylene glycol solution, although the cooling effect is limited due to the physical properties of water, it is more environmentally friendly and degradable.   The commonly mentioned liquid cooling system consists of pumps, fans, oil tanks, and connecting pipes, a compact system with high cooling capacity. It can be divided into automatic control and non-automatic control liquid cooling systems, depending on whether the charger needs to control the operation power of the pump and fan.   Liquid Cooled Charging Connectors According to the standards they meet, liquid-cooled charging connectors can be divided into CCS2/CCS1/NACS (TESLA DC)/GB/T/CHAOJI liquid-cooled charging connectors, which are used in corresponding standard DC Fast Chargers. The CCS2 is a combined AC and DC charging interface, with the standard referring to IEC 62196. It applies to Europe and most regions. The upper part is the AC interface, the lower part is the DC charging interface, and there are no electronic locks or hooks.   The CCS1 is also a combined AC and DC charging interface, with the standard referring to SAE J1772. It applies to the United States and countries such as Japan and South Korea. The upper part is AC and the lower part is DC interface, without electronic locks and with hooks.   NACS is the new charging interface announced by Tesla, and its current standard is defined as SAE J3400. It uses a shared AC and DC interface, without electronic locks and hooks.   The GB/T charging connector is based on Version2015 of the DC charging plug to develop the liquid-cooled plug, with the electronic lock on the charging connector and with hooks.   CHAOJI is a new standard jointly developed by China, Japan, Germany, and other countries, without electronic locks and hooks.   As a leading global professional charging plug solution provider, Workersbee’s CCS1 and CCS2 charging plugs adopt an integrated design, simple generous, and easy to handle. At the same time, they are compatible with natural cooling and liquid cooling.   The charging peak of the CCS2 liquid-cooled charging plug can reach 700A, with a rated current of 500A. With its safe and reliable performance, it has passed CE and TUV certifications and has always been a trusted partner of customers. For high-frequency use plug terminals, from the perspective of maintenance costs of business partners, the terminal quick change design is applied to avoid the high cost of replacing the whole piece. This technology has also received positive feedback from the market.   How Does Liquid Cooling Help High Power Charging? Liquid cooling technology plays a crucial role in High-power Charging. Uses liquid to absorb and transfer heat, achieving efficient heat dissipation, ensuring that charging equipment can maintain an appropriate and stable temperature range during high power operation, thereby safety and reliability of the charging process.   The power pump promotes the circulation of the cooling liquid, which carries away a large amount of heat, significantly improving the current transmission efficiency of the charging cable and reducing the risk of cable damage due to overheating.   Since the liquid cooling technology can effectively reduce the temperature of the charging system, it allows for higher charging currents and voltages, achieving faster charging speeds and improving charging efficiency. It ensures the system's stable operation and extends the service life of the equipment.   Benefits of Liquid Cooling Technology for Businesses 1. Enhance heat dissipation efficiency and performance of equipment to ensure stable and efficient charging. 2. The efficient liquid cooling mechanism can further save energy and improve work efficiency. 3. Charging station design can be more flexible, and better adapted to specific environmental, space, and electrical needs. 4.

In the previous article, we discussed the importance of liquid cooling technology for DC Fast Charging, which enables electric vehicles to achieve excellent charging experiences. This includes enhancing the charging power limit of High-power charger (HPC), achieving more efficient, energy-saving, and reliable charging.     Why Liquid Cooling Matters in DC Fast Charging   As EV adoption accelerates, the demand for ultra-fast, efficient, and safe charging solutions grows rapidly. Liquid cooling technology has become a critical enabler in High Power Charging (HPC), allowing systems to safely deliver 500A and beyond without overheating.   Previously, we explored the role of liquid cooling in enhancing thermal management. In this article, we'll take a closer look at the core components of liquid-cooled EV charging systems, and how Workersbee's 500A liquid-cooled CCS2 charging cables offer a competitive edge for your EV charging infrastructure.   What Is a Liquid-Cooled EV Charging Plug?   A liquid-cooled EV charging plug is engineered to manage the extreme heat generated during high-current DC charging. It consists of several essential components:   ·Coupling Part ·Enclosure ·Liquid Cooling Assembly ·Terminal Pin ·Sealing System ·Cable Clip   Spotlight: The Liquid Cooling Assembly   The core of the plug’s thermal regulation lies in the liquid cooling module, which actively disperses heat from critical contact points during high-power charging. During high-current charging, the terminal pins heat up more than the cable conductors, due to contact resistance. To mitigate this, a cooling structure is built around the pins, enabling forced liquid cooling using a circulating coolant.   The assembly is designed for:   ·Simple and efficient structure ·Easy manufacturing ·Excellent temperature rise control   Its structure typically includes:   ·Dual-sided coolant inlets/outlets (using smooth “pagoda-style” joints) ·Thermal conductive material (for heat transfer without direct coolant-metal contact) ·Fixing nuts, seals, and mounting screws   This design ensures effective cooling while maintaining electrical insulation and operational safety.     Inside the Liquid-Cooled Cable: Structure & Design Highlights   Unlike standard DC charging cables, liquid-cooled EV charging cables integrate a coolant channel within the cable itself. Here's how it works:   ·A liquid cooling tube runs through the center, carrying coolant ·The conductor wraps around the tube ·An insulated outer layer protects the system   This integrated design determines the internal layout of the plug and the cooling performance of the system.   Key Design Requirements for Public Charging Infrastructure    To ensure long-term performance, the following are essential in cable design:   1. High flexibility – Prevents cable stiffness and enhances usability. 2. Proper outer diameter – Avoids weak thin jackets while staying compact. 3. Low sheath temperature rise – Improves safety and comfort for users. 4. Strong welding – Guarantees a stable electrical connection for the pin-conductor joint.       The Role of the Liquid Cooling Tube   The cooling tube is a critical component, affecting both thermal transfer and coolant flow efficiency. Here's what matters:   ·A narrower internal channel within the cooling tube increases resistance to coolant flow, which can significantly hinder the system’s ability to remove heat effectively.     ·Outer diameter: Must balance strength, flexibility, and lightness. ·Material: Requires good chemical resistance, elasticity, and toughness.   Longer cables may generate more heat and higher resistance, so it's essential to balance cable length vs cooling efficiency.       Liquid Cooling System: How It All Circulates   Beyond the cable and plug, a complete liquid-cooled EV charging system includes:   ·Coolant pump ·Radiator/heat exchanger ·Coolant reservoir (oil tank) ·Connecting pipes     Working Principle   1. Heat generated during charging is absorbed by the coolant. 2. Once the coolant absorbs excess heat from the charging components, it flows into a heat exchanger, where thermal energy is transferred out before the liquid recirculates. 3. The coolant is returned to the reservoir and pumped back into the plug.   Advanced systems include temperature, pressure, and level sensors, enabling automatic operation with smart controls. Chargers typically only need to supply power and start signals.       Why Choose Workersbee's 500A Liquid-Cooled Charging Cable?   Workersbee's 500A CCS2 Liquid-Cooled Charging Cable is designed to deliver reliable high-power charging for demanding public and fleet applications.
