More Information
Summary:The invention provides a vehicle power supply system which can realize high-power-efficiency driving in a two-wheel driving mode. A vehicle power supply system is provided with: a first drive motor (Mr); a second drive motor (Mf); a first power line (21) to which the first inverter (3r) and the first battery (B1) are connected; a second power line (22) to which a second inverter (3f) and a secondbattery (B2) are connected; a voltage converter (4) for converting a voltage between the power line (21) and the power line (22); and a charge/discharge control device for controlling the charge/discharge of the battery (B1) and the battery (B2) by operating the inverter (3r), the inverter (3f), and the voltage converter (4). The vehicle can travel in any one of an all-wheel drive mode and a two-wheel drive mode. When the drive mode is a two-wheel drive mode, the charge/discharge control device drives the first drive motor (Mr) using the power discharged from the first battery (B1). 本发明提供一种可在二轮驱动模式下实现电力效率高的行驶的车辆电源系统。车
