11kw on-board charger

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

### Key points:
- **On-board** means the charger is installed inside the vehicle.
- It works with **AC charging stations** (such as home wallboxes or public AC chargers).
- The **11 kW** rating indicates the maximum charging speed it can handle.
- It typically requires a **three-phase AC power supply** to reach the full 11 kW rate.
- Actual charging speed may be lower depending on the power source and electrical setup.

For example, with an 11 kW on-board charger, a 55 kWh battery could theoretically charge from empty to full in about 5 hours under ideal conditions.
