Embodiment Construction

[0021] Various embodiments disclosed herein relate to connectors with integrated thermal switching devices (eg, thermal cut-offs (TCOs)) configured to respond to overtemperature conditions and / or in battery packs or battery cells or an overcurrent condition is detected, and the detection is relayed to an electrical device such as a battery management system (BMS). In various embodiments, a temperature sensitive battery connector is disclosed. The connector may include a connector body and at least one conductor mounted to the connector body and configured to transmit a signal by which the temperature of the battery pack or battery cell is determined by the battery management system (BMS) as Threshold level has been exceeded. The connector may include a thermal switching device (eg, a TCO) mounted to the connector body and thermally coupled to the terminals of the battery pack or battery cells. The thermal switching device can be configured to provide a power supply for balan...

Abstract

Disclosed is a temperature sensitive type battery connector. The connector may include a connector body and at least one conductor mounted to the connector body and configured to communicate a current signal for measuring a voltage from the battery pack or battery cell to a battery management system (BMS). The connector may include a thermal switching device mounted to the connector body and thermally coupled to a terminal of the battery pack or battery cell. The thermal switching device may be configured to provide an over-temperature signal to the BMS by changing or interrupting a current conducted by the at least one conductor when a temperature of the battery pack or battery cell exceeds a threshold temperature.

Description

[0001] Incorporated by reference into any priority application [0002] Any and all applications that identify foreign or domestic priority claims in the Application Data Sheet filed with this application are hereby incorporated by reference under 37 CFR 1.57. technical field [0003] The field relates to integrated thermal cutoff devices for sensing the temperature of a cell or battery pack. Background technique [0004] In various types of electrical systems, circuit elements or other components, such as batteries (which may include one or more cells), may experience failures that negatively affect the operation or reliability of the larger electrical system. For example, a battery pack may experience an increase in temperature during operation or charging. If the temperature rises too much, a single cell or battery pack, or a larger electrical system may be damaged by overtemperature and / or overcurrent failures. Such overtemperature failures may reduce the functionality...
