Abstract
A busbar for a battery pack, intended to electrically connect at least one electrochemical accumulator battery of the pack, preferably to electrically connect several electrochemical accumulator batteries of the pack to one another, including an electrically conductive and sealtight envelope itself intended to channel the current of the accumulator batteries and designed to contain a heat transfer liquid whose vaporization temperature is chosen so as to be between a value close to 90% of the self-heating temperature and a value close to 110% of the thermal runaway temperature of the accumulator batteries of the pack, the sealtight envelope being designed to guarantee an injection of heat transfer liquid as close as possible to each accumulator battery to which it is intended to be connected, preferably close to at least one of its output terminals.
