Abstract
A method of preventing an energy storage device failure in a power supply, includes a package deformation, indicating a gas buildup and a forthcoming failure in a package wall of the energy storage device is detected. A voltage caused by the displacement of the package wall of the energy storage device is detected. It is determined whether the detected voltage is greater than or equal to a voltage threshold to indicate a slight package deformation. A warning is issued if the detected voltage is greater than or equal to the voltage threshold for the slight package deformation. It is determined whether the detected voltage is greater than or equal to a voltage threshold, to indicate a package deformation severe enough that a package breach is imminent. The power supply is shut down if the detected voltage is determined to be greater than or equal to the package breach voltage threshold.
