Abstract: Reliable connecting of power battery box is important for safe-running in electric vehicle with exchanging battely technology. According to the characteristics of operation and connection of power battery box , the connecting failures of power battery box were analyzed. A solution was presented to detect the poor contact of terminal posts and achieve the protection. And a corresponding protection terminal was designed and developed. By means of simulating poor contacting and malfunction of terminal posts of power batter box , some criterion parameters for detecting the malfunction were presented and the availability of the protection solution was also verified.

Key words: electric vehide, power battery box, exchange battery technology, poor contact of terminal posts, arcing
