Abstract: 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.

Abstract: A device includes two electrically conductive rods to couple to connection terminals of a battery cell of a battery, with a force tending to squeeze the electrically conductive rods together. The device includes an insulating block to keep the electrically conductive rods from making electrical contact with each other. An insulating block disable element disables the insulating block in response to a control signal generated by a disable element controller. The disable element controller monitors at least one operating state signal of the cell, and generates the control signal based on the monitoring, allowing the rods to come into electrical contact and short-circuit the battery cell.

Abstract: A battery powering a propulsion engine of a vehicle, is controlled by determining state data representative of the operation and wear of the battery, authenticating state data using an encryption method, and transmitting authenticated state data to an on-board computer of the vehicle for display.
