Abstract: New energy vehicles have the characteristics of many controllers and fast program update speed. In order to solve the problem of timely updating the program of the controller of the off-line vehicle of the vehicle manufacturer, this paper expounded a method of developing host computers based on C++. By the method of increasing channel selection window of the host computer, using the same host computer to open different windows and select different channel settings, multi-type controllers can be flashed synchronously, and the functions of automatic recognition and automatic flashing again, monitoring and flashing data, and automatic reset controller re-flashing can be realized after replacing the hardware, which greatly reduced the time cost and labor cost of the vehicle manufacturer to upgrade the controller for the off-line vehicle.
