Design of Energy Management Systems for Mobile Power Station of Electric Vehicles

The current development and situation of electric vehicle battery charging station are introduced and analyzed, and a design scheme of mobile power station for electric vehicles is presented. The mobile power station for electric vehicles in this scheme can directly get electricity to drive the electromotor from the electricity supply grid for electric vehicles or oil dual-mode electric drive motor-powered vehicles, and it can also charge the battery of electric vehicles in the driving process of vehicles. Power management system that includes the managements of the information of identifying the custom, energy metering, self-management of pricing and settling accounts and warning to custom is core design of mobile power station for electric vehicles, which is the key to realize the function of the mobile power station that automatically provides electricity without manpower. The design of hardware and software for the system is expatiated in this paper, which includes circuit design of the modules of data collecting, transmitting and processing based on IC cards and single-chip technology, the software system and the main programs to realize the functions of the system.
