Research of Control Method in Multi-Working Condition to Charging and Discharging under Multi DC/DC Modules

This paper is based on the development process of charge-discharge experiment platform of electric cars under multi-working condition and more modules, it can carry out much charge-discharge experiment under several of control modes and parameters, and it contains lots of functions, like modular control, data collection, on-off control, human-computer interaction and environmental monitoring. There are 6 DC/DC modules in this platform, to realize these modules run independently under one backstage control system, meanwhile one module can change working condition ongoing, status inquiry and in-out operation automatic, this article proposes a new control method. It comes true by identifying critical parameters and taking into account many situations, finally we give the flow process of the method. The conclusion claim that this method could meet the request of the platform, and it has certain of reference price to such platform.
