【Abstract】 The hardware and software design of digital system for testing power battery is introduced. The system uses TMS 320 LF 2407 DSP as the core processor and adopts principal-subordinate structure, so it can adjust the output current by controlling digital pulse-width modulating with DSP and FPGA technology. The system is used for monitoring and controlling the performance parameters such as voltage, current, capacity and-?驻V of power battery timely during charge or discharge. Results show that it has such advantages as high reliability and precision, responding quickly and handling easily. It can satisfy all test requirements, and especially it’s appropriate for the large-scale test of power battery.更多还原
