Onboard Charger
The onboard charger converts AC from a socket or wallbox into DC to charge the high-voltage battery.
What is Onboard Charger?
Its power rating, for example 7 kW or 11 kW, limits how fast the car charges on AC. Three-phase chargers are common in Europe. DC fast charging bypasses it. Some cars support bidirectional charging, so the onboard charger can also feed energy back to a house or devices.
How it works
It rectifies and controls the AC input and talks to the charging station.
Why it matters for your car
A faulty charger stops AC charging while DC may still work. Charging speed is set by the lower of charger and station power.
