The invention relates to the technical field of vehicle control, and particularly discloses a battery power supply control system and method and an electric vehicle. The battery power supply control system comprises a high-voltage power supply module, a low-voltage power supply module and a power supply control module, the low-voltage power supply module is used for converting a power supply of a battery pack into a first power supply signal, outputting the first power supply signal to supply power to the master-slave controller, and transmitting the first power supply signal to the power supply control module; and the power supply control module is used for driving the low-voltage power supply module to stop and driving the high-voltage power supply module to convert the power supply into a second power supply signal of which the power is gradually reduced when the amplitude of the first power supply signal is detected to be abnormal, and supplying power to the master-slave controller by using the second power supply signal. The high-voltage power supply module and the low-voltage power supply module are used for supplying power to the master controller and the slave controller respectively, and the situation that the vehicle performance is limited and abnormal power failure is caused by wire harness abnormity is avoided.
本发明涉及车辆控制技术领域,具体公开了一种电池供电控制系统、方法及电动汽车。该电池供电控制系统包括:高压供电模块、低压供电模块和供电控制模块;所述低压供电模块,用于将电池包的供电电源转换为第一供电信号,输出所述第一供电信号为所述主从控制器进行供电,并将所述第一供电信号传输至所述供电控制模块;所述供电控制模块,用于在检测到所述第一供电信号的幅值异常时,驱动低压供电模块停止,驱动高压供电模块将所述供电电源转换为功率逐渐降低的第二供电信号,使用所述第二供电信号为所述主从控制器进行供电。通过高压供电模块以及低压供电模块分别为主从控制器进行供电,避免线束异常导致车辆性能受限以及异常掉电状况的发生。
