摘要：
The present disclosure relates to methods for monitoring the health of a battery cell. Specifically, the method includes receiving, by a controller communicatively coupled a pressure sensor positioned proximate to a battery housing having an initial volume and an initial shape and containing a battery cell, a pressure value indicative of a current volume or a current shape of the battery' housing. The pressure sensor is configured to measure the pressure value indicative of the current volume or the current shape of the battery' housing. The method also involves comparing, by the controller, the pressure value to a predetermined threshold pressure value. The method further involves adjusting, by the controller and based on the comparison, at least one parameter associated with operations of the battery cell.
