ABSTRACT:
The subject matter of this specification can be embodied in, among other things, an apparatus that includes a battery system, which includes at least one cell and a charge enable device to couple the at least one cell to a charging voltage. The apparatus also includes an excessive voltage detector to output a signal to control the charge enable device. The signal prevents charging of the at least one cell if an excessive charging voltage is detected based on an activation of a clamping component.
