onboard charger 11kw

An **onboard charger (OBC) 11 kW** is a built-in charging device in an electric vehicle (EV) that converts alternating current (AC) from an external power source into direct current (DC) to charge the vehicle’s battery, with a maximum charging power of **11 kilowatts**.

### Key points:
- **Onboard**: Installed inside the vehicle.
- **11 kW**: The maximum AC charging rate it can handle.
- Typically used with **three-phase AC power** (common in Europe and some other regions).
- Charging speed depends on the power supply — with a compatible 11 kW AC charger, it can add roughly **50–70 km (30–45 miles) of range per hour**, depending on the vehicle.

It is different from **DC fast charging**, where the power conversion happens outside the vehicle.
