Design on Management System for Traction Battery Packs in Electric Transmission Vehicle

According to the application quality and request of traction battery packs which is used in electric transmission vehicle,Management system for battery packs is designed by the way of bus communication.The management system is composed of many single battery test modules and an integrated battery packs monitor.In order to overcome the high-voltage disturbance on battery packs,a new type of collection circuit called constant current source controlled by voltage is designed in Single battery test module,which realizes the precise collection to voltage of each battery.Via the application in electric transmission vehicle,it is sure that the whole system works well and stable,has the good ability to expand,is convenient for installation and arrangement,achieving the wide application foreground.
