They are　the reasonable structure; monitoring batteries and analyzing the data;　internal resistance testing and alarming; running accident recording;　remote management. Combining with the experience from developing the BM-6500 series of battery management systems, the related problems have been discussed in this paper. this system can promote the reliability of DC power sources which service in DCpower systems.
