Abstract

See full text

A method includes coupling two conducting rods between terminals of a battery cell of a battery having several branches coupled in parallel, each branch having several battery cells coupled in series. A force tending to squeeze the rods against each other is applied, with the rods being held apart from each other using an insulating block. At least one operating state signal of the cell is monitored, and the insulating block is removed based on the monitoring, allowing the rods to come into electrical contact and short-circuit the battery cell.
