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.

Connector with integrated thermal cutoff device for battery pack

A connector for providing electronic communication with an electronic device is disclosed. The connector can comprise a substrate comprising layers of non-conductive material and conductive material. The connector can include an interface member mounted to the substrate and electrically connected with the conductor. A positive temperature coefficient (PTC) fuse can be embedded in the substrate and electrically connected with the conductor and the interface member. At least a portion of the PTC fuse can be disposed directly below the interface member.

Connector with integrated resettable thermal fuse

Electromechanical circuit breakers are disclosed herein. In some embodiments, the breakers can be integrated into battery management systems to simplify battery management circuitry and/or to provide redundancy to the battery management systems. In some embodiments, the breakers can be provided to reduce damage to the battery management systems during hot-swapping of a battery cell. The breakers can be automatically resettable or not automatically resettable in various embodiments.
