SYSTEM AND METHOD FOR VEHICLE POWER MANAGEMENT |
| 摘要 |
A power management system for a vehicle having wheels and an electric machine operable to provide torque to drive at least one of the wheels includes a first energy storage system capable of supplying power to operate the electric machine. The system also includes a second energy storage system capable of supplying power directly to at least one vehicle load at a lower voltage than the first energy storage system. A voltage conversion device is operable to reduce a voltage of the power supplied by the first energy storage system to the lower voltage to charge the second energy storage system when the vehicle is in a key-off state. |

1. A method of power management for a vehicle having wheels and an electric machine operable to provide torque to drive at least one of the wheels, a high-voltage battery for providing power to the electric machine, and a low-voltage battery, the method comprising:
reducing voltage of the power from the high-voltage battery during a vehicle key-off state; and charging the low-voltage battery with the reduced voltage power. |
