HIGH VOLTAGE SERVICE DISCONNECT ASSEMBLY AND METHOD FOR DETERMINING AN ISOLATION RESISTANCE FAULT OF A BATTERY PACK

摘要

A high voltage service disconnect assembly is provided. The battery pack has an enclosure, first and second battery modules, and positive and negative pack voltage terminals. The assembly includes a housing securing first and second conductive pins thereon. The first conductive pin is coupled to a negative voltage terminal of the first battery module. The second conductive pin is coupled to a positive voltage terminal of the second battery module. The assembly further includes a detection circuit electrically coupled to the first and second conductive pins. The detection circuit outputs a first isolation resistance fault signal when a first isolation resistance fault is detected between the negative pack voltage terminal and the enclosure.
