In order to keep storage battery active,a new intelligent battery discharging device that feedbacks energy is proposed in this paper. The device uses DSP to control the whole system. The major difficulty involved in this research is to control the discharge current. The device has been developed in the factory and test results in power system plants and substations are presented. The test results show the good agreement with the emula-tion and the developed system can satisfy the constant-current discharge of different capacity batteries.
