The invention provides an extended-range electric vehicle test vehicle safety power supply control system and method, and relates to the technical field of test vehicle safety power supply. Comprising an emergency stop switch, the emergency stop switch is arranged on a low-voltage power supply circuit, and the low-voltage power supply circuit is used for supplying power to a vehicle control unit and a battery management system. The emergency stop switch is additionally arranged between the weak current power supply circuit and the engine management system, the vehicle control unit and the battery management system, the added emergency stop switch serves as safety protection equipment, and when electric leakage occurs and power output cannot be controlled to be cut off through signals, the safety protection equipment switch can be pressed down, and a high-voltage interlocking strategy is combined, so that the power output can be controlled to be cut off. Therefore, the high-voltage power output is safely and reliably cut off, so that the safety of testers is ensured, and the safety and reliability of a test vehicle are improved.
本发明提出了增程式电动车试验车辆安全供电控制系统及方法,涉及试验车辆安全供电技术领域。包括急停开关,所述急停开关设置于低压供电线路上,所述低压供电线路用于为整车控制器和电池管理系统供电。本发明通过在弱电供电线路与发动机管理系统、整车控制器、电池管理系统之间增加急停开关,将增加的急停开关作为安全保护设备,在发生漏电、动力输出无法通过信号控制切断的情况时,可通过按下安全保护设备开关,结合高压互锁策略,切断电池包对外供电,实现安全可靠的切断高压动力输出,以保证测试人员安全,提升试验车辆的安全性和可靠性。
