BATTERY PACK WITH LOCALLY CONTROLLED DISCONNECT SAFEGUARDS

摘要

Embodiments of the present invention are directed to an improved battery packaging design. The battery pack design may include a battery cell, a plurality of transistors, and a controller. The transistors may be coupled to the terminals of the battery cell in an H-bridge configuration. The controller may control the transistors to bypass the battery cell based on the current flowing between the output terminals of the battery pack. In such a manner, the controller may prevent damage to the battery cell and improve the overall safety of the battery pack in hazardous conditions.

主权项

1. A battery pack comprising:
a battery cell; a pair of output terminals; two pairs of switches coupling the battery cell to the output terminals in an H-bridge configuration; and a local controller to control the switches to selectively connect and disconnect the battery cell to the pair of output terminals, wherein the battery cell, the switches, and the local controller are provided in a common package.
