【Abstract】This study mainly introduces the current situation and main problems of the adhesion detection technology scheme of the main and negative relays in electric vehicles. And it also focuses on the application of a detection scheme for the new main negative relay adhesion in power battery systems. Through appropriate simulation analysis,it can effectively simulate the real operating condition and provide a reference for the development of BMS(battery management system)in electric vehicles.

【Key words】electric vehicle;main negative relay;adhesion detection;simulation analysis
