The Monitor And Diagnostic Management System Of Storage Battery

The low performance and cost of the battery are the bottleneck of today's electric vehicle development. There are two ways to resolve the battery problem. One is to develop new high energy batteries, which is in progress and will be a long time before the new batteries are accepted. The other way is the use if the battery management system or a BMS.A good BMS can raise the efficiency of the energy and reduce the cost whit a longer service life of the battery.In this paper, a Battery monitor and diagnostic Management System is described in detail. First , it introduced the characteristics of Lead-Acid batteries and method of battery diagnosis , then introduced BMS relative theory in detail , include method of capacity computation , method of evaluation of battery running capability ,method of fault diagnosis ,and the algorithm of application. After these it introduced BMS's system design base the theory introduced before and the method of system implement. At last it introduced BMS's system structure and module implement detail.
