Abstract
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.
