Abstract

A temperature-sensitive battery connector is disclosed. The connector can include a connector body and at least one conductor mounted to the connector body and configured to convey a current signal used to measure voltage from a battery pack or battery cell to a battery management system (BMS). The connector can include a thermal switching device mounted to the connector body and thermally coupled to a terminal of a battery pack or a battery cell. The thermal switching device can be configured to provide an overtemperature signal to the BMS by changing or interrupting a current conducted by at least one conductor when a temperature of the battery pack or battery cell exceeds a threshold temperature.
