Abstract
A vehicle on-board electrical system having an AC voltage charging connection, a rechargeable traction battery, which is designed as a high-voltage rechargeable battery, and a power factor correction filter. The power factor correction filter connects the AC voltage charging connection directly to the rechargeable traction battery. The operating voltage range of the rechargeable traction battery is within the output voltage range of the power factor correction filter.
Claims11
A vehicle on-board electrical system, comprising:
- an AC voltage charging connection;
- a rechargeable traction battery;
- a power factor correction filter, which directly connects the AC voltage charging connection to the rechargeable traction battery;
- and
- a controller which is connected to the power factor correction filter in a driving manner;
- wherein the controller switches the power factor correction filter from a single-phase operation to a three-phase operation when a terminal voltage at the rechargeable traction battery reaches a minimum three-phase voltage.
