The invention relates to a device and method for detecting an external discharge function of an electric automobile, a signal line is adopted to send a self-inspection signal to an automobile end controller through a signal terminal, the automobile end controller receives the self-inspection signal and then judges whether the self-inspection signal meets the requirement of discharging electric energy or not, and if the self-inspection signal meets the discharge requirement, the automobile end controller sends the self-inspection signal to the external discharge function of the electric automobile. The vehicle end controller controls the discharging device of the electric vehicle to discharge, the power supply terminal transmits electric energy to the circuit board through the cable, the driver on the circuit board drives the alarm device to work, and the external discharging function of the vehicle is detected to be normal. By adopting the detection device and the detection method, whether the external discharge function of the electric automobile is normally used or not can be quickly and accurately detected, and the use feeling and the working efficiency of testers are improved.

    本发明涉及一种电动汽车对外放电功能检测装置及检测方法,采用信号线通过信号端子将自检信号发送给车端控制器,车端控制器接收到该自检信号后对其进行判断,看是否符合将电能放出的要求,若自检信号符合放电要求,车端控制器控制电动汽车的放电装置进行放电,电源端子将电能通过电缆线传输给电路板,电路板上的驱动器驱动报警装置工作,车辆的对外放电功能检测正常,通过采用此检测装置及检测方法能够快速、准确的检测电动汽车的对外放电功能是否正常使用,提高了测试人员的使用感和工作效率。
