AI Technical Summary

Problems solved by technology

In addition, the internal parameters of the battery module may change at different rates or to different extents during use
If the difference in internal parameters between two battery modules is unacceptably large, the risk of arcing, fire or other hazards increases significantly
[0006]Furthermore, if two battery modules are at significantly different SOCs, the battery module with the larger SOC will discharge to the battery module with the smaller SOC, and the total power output will drop significantly
In addition, significantly different SOC between battery modules may cause backflow current, which may damage the battery modules

Abstract

A battery module includes a set of power contacts, a set of signal contacts, and a battery pack operable to deliver power to the set of power contacts. The electronic insulation system is operable to electrically disconnect and connect the battery pack and the power contact set. The electronic control system is electrically connected to the electronic insulation system and to one of the set of signal contacts or the set of power contacts. The electronic control system is operable to measure a parameter associated with one of the battery module and the electrical device and compare the parameter to a predetermined value. The electronic insulation system connects the battery pack to the set of power contacts based on a positive result of the comparison and disconnects the battery pack and the set of power contacts based on a negative result of the comparison.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This patent application claims priority to US Provisional Patent Application No. 62 / 892,804, filed on August 28, 2019, entitled Battery Interlock Detection System. The entire contents of the above application are incorporated herein by reference. technical field [0002] The present disclosure relates to battery modules. More specifically, the present disclosure relates to battery modules with electronic isolation and power flow control systems. Background technique [0003] A battery module system is a set of any number of battery modules, where each battery module includes a battery pack. Each battery pack includes one or more battery cells. The multiple battery modules of a battery module system can be electrically configured in series, parallel, or a mixture of the two to provide the desired voltage, capacity, or power density required for any number of applications. Battery module systems are used in energy-intensive b...
