Application of wireless communication module based on nRF905 in battery Quick Change of electric vehicle

The Application of Electric Vehicle (EV) has been limited by the problems of power battery. Battery Quick Change System was used efficiently to solve these problems. Based on wireless transceiver nRF905 and single chip MC68HC908GZ16, the wireless communication module was designed for the BQCS, which was used on battery cases quick changing of pure electric bus. The remote-control, quick location, automatic unlocking and manual/automatic mode change were realized. The system was applied on the buses for Beijing Olympic Games. Results indicate that the system shows stably and reliably operation qualities and meets the requirements of the pure electric buses.
