VEHICLE DRIVING SYSTEM AND METHOD

摘要

Disclosed are a vehicle driving system and method. According to an embodiment of the present invention, the vehicle driving system converts a voltage of a second battery section, which supplies power to electric parts inside a vehicle, into a voltage of a first battery section, which supplies power to an inverter for operating a motor through a converter; and supplies power having the converted voltage to a capacitor of the inverter when the vehicle starts so that the capacitor can be charged with the power. With this, the pre-charge circuit is removed from the battery system to thereby make the battery system inexpensive, small and light weight.

主权项

1. A vehicle driving system comprising:
an inverter which comprises a capacitor and operates a motor; a first battery section which supplies power to the inverter; a second battery section which supplies power to electric parts inside a vehicle; and a converter which converts a second voltage of the second battery section into a first voltage of the first battery section, and supplies power having the converted voltage to the capacitor when the vehicle starts, so that the capacitor can be charged with the supplied power.
