Slow but simple. Good for low daily mileage or overnight top-ups. Level 2 (240V single-phase / 230V in many regions)The mainstream choice for home: commonly 3.6–7.4 kW on single-phase; 11–22 kW where three-phase is available. DC fast charging at homeRare due to cost, power requirements, and noise/space. Most homeowners don’t install DC fast chargers. The OBC bottleneckYour EV’s on-board charger (OBC) caps the AC charging rate. If the car’s OBC is 7.4 kW, a 22 kW wallbox won’t make AC charging faster.     Charging Options Comparison Level Typical Power (kW) Add-Range (mi/h)* Pros Cons Best For Level 1 (120V) 1.2–1.9 ~3–5 Cheapest to start; use any outlet (properly rated) Slow; can stress old outlets Light daily driving, renters Level 2 (single-phase) 3.6–7.4 ~15–30 Fast overnight; broad compatibility Requires dedicated circuit/installer Most households Level 2 (three-phase) 11–22 ~35–60 Very fast AC at home (if supported) Needs three-phase supply; car OBC may limit High daily mileage, EU homes *Rule-of-thumb conversions for planning only; real results vary by vehicle efficiency and conditions.     How Long Charging Takes Head terms: EV charging time at home, how long to charge an EV at home, Level 2 charging time, 7.4 kW charging time Simple formula:Time (hours) ≈ (Energy to add in kWh) ÷ (Effective power in kW) Where: Energy to add (kWh) = Battery capacity × (Target SOC − Start SOC) Effective power (kW) = min(charger power, OBC limit) × efficiency factor (≈0.9)     Example Time Matrix (estimates) Assumptions: efficiency 90%; OBC ≥ charger power.

A Common Question Among EV Drivers If you’ve recently switched to an electric vehicle (EV), you’ve probably asked yourself: Can I use my car while it’s charging? Many EV owners wonder whether it’s safe to turn on the air conditioning, listen to music, or sit inside the car while it’s plugged in. Others even ask if the vehicle can be driven during charging.   The short answer is yes, you can usually turn on your EV systems while charging — but no, you cannot drive it.Let’s explore why that’s the case, what happens during charging, and how to do it safely.     What Happens When Your EV Is Charging When an EV is plugged in, the battery management system (BMS) takes control. It regulates voltage, current, and temperature to make sure energy flows safely from the charger to the battery pack. At the same time, most EVs automatically lock the drive system, preventing the car from moving until charging stops. There are three main charging levels: Level 1 (standard home outlet) – slow, overnight charging. Level 2 (dedicated AC charger) – faster, typical for home or workplace. DC fast charging – very high power, found at public stations.   Each level has built-in communication between the charger and the vehicle to manage power safely.     What You Can — and Can’t — Do While Charging “Using your car” can mean different things. You can’t drive it, but you can still use many of its systems while it’s plugged in. ✅ You can safely: Turn on the infotainment system to listen to music or check settings. Use climate control to pre-cool or pre-heat the cabin (a common EV feature). Turn on interior lights or charge small devices through USB ports. Monitor charging progress on the dashboard or mobile app.   You cannot: Shift into Drive or Reverse. Move the vehicle (most cars are locked in Park). Engage the motor or regenerative braking systems.   Modern EVs are designed this way for a reason. When you turn the car on during charging, the vehicle simply uses grid power or battery power for limited systems while maintaining a safe charging current.     Is It Safe to Keep the Car On While Charging? Generally, yes — as long as you’re using certified equipment and good-quality cables.Safety risks usually arise when the cable, connector, or charger is substandard or damaged. Potential risks include: Overheating due to poor cable insulation. Current surges when high-power systems (like heaters) are used simultaneously. Reduced charging efficiency if energy is drawn to run accessories.     Home vs. Public Charging Scenarios Your charging environment also affects what you can do while the car is plugged in.   At Home Power levels are usually lower (16–32 A), making it safe to sit inside the car with systems like air conditioning or seat heating turned on. Because the current is steady, using minor accessories won’t noticeably affect charging time. A wall-mounted charger, such as those compatible with Workersbee’s Level 2 charging cables, offers reliable overnight charging with built-in safety features.   At Public Fast Chargers Power output is much higher (up to 350 kW). Some vehicles automatically disable most onboard systems for safety. It’s recommended not to stay inside the car for long or use high-load features.   Using properly certified public chargers and cables ensures safe operation in both environments.     Can You Drive and Charge at the Same Time? This question often comes up — and the answer is no, at least not yet.Physically, a car plugged into a stationary power source cannot move safely. The connectors are designed to lock in place and instantly cut power if unplugged.   However, new technology known as dynamic wireless charging (or in-motion charging) is being tested in parts of Europe and Asia. These systems use embedded coils under road surfaces to transfer energy wirelessly to the vehicle as it drives.     Best Practices for Safe and Efficient Charging To keep both your car and your charger in top condition, follow these simple best practices: Use certified cables and connectors — look for CE, UL, or TUV marks. Avoid running unnecessary systems (like high-heat seat warmers) while charging. Check your cable and plug temperature occasionally. Ensure good ventilation, especially in enclosed garages. Follow your manufacturer’s charging guide to maintain battery health.     FAQ Can I use the AC or heater while charging my EV?Yes. Most EVs allow pre-conditioning while plugged in, drawing power directly from the grid instead of the battery.   Does using the car slow down charging?Slightly — using major systems can divert small amounts of energy, but it’s negligible with Level 2 or higher chargers.   Is it safe to sit inside the car during charging?Yes, as long as you’re using certified equipment and the area is well-ventilated.   Can I drive while charging?No. Once charging starts, the drive system is locked for safety.     Safe to Use — With the Right Equipment So, can you use your electric car while charging?Absolutely — as long as you understand the limits. You can safely operate onboard systems such as air conditioning or infotainment, but never drive or move the car during charging.   Safety always depends on equipment quality. Using certified, high-grade connectors and chargers, like those designed by Workersbee, ensures optimal performance and peace of mind.     Learn More About Smart and Safe Charging Charging safely starts with the right technology.If you’d like to learn more about reliable EV charging solutions, explore Workersbee’s range of certified chargers, cables, and connectors — engineered to meet international safety standards and support both home and commercial charging needs.   With innovation rooted in quality and safety, Workersbee helps every EV driver charge smarter, safer, and faster.
