Research and Design of DSP-Based Monitoring System of Power Batteries

In order to realize the monitoring of the power battery pack's instantaneous state, a monitoring system based on Digital Signal Processor (DSP) is designed. The digital signal processor (TMS320F2812) with well performances is employed to collect, analyze and make numerical dealing with the power battery pack's parameter of state, and the data is transmitted to PC through the DSP's serial port. The visualization software interface is developed with VB6.0 on PC. The software interface can show various parameters of power battery pack for each battery or the whole. The examination results show that this design is not only simple, but also fast and precise at data obtaining especially for the State-Of-Charge (SOC). This system can be a kind of auxiliary equipment for large scale Battery Management System (BMS).
