The invention relates to a device for the thermal management of a battery of electric accumulator cells assembled within a rigid casing, said device comprising thermal storage means incorporated into said battery comprising a chamber containing a phase-change material and having a volume for exchange of heat with said accumulator cells which is delimited by at least part of said casing, the melting of the phase-change material being able to store heat, and the solidification of the phase-change material being able to release the heat previously stored. According to the invention, said chamber is equipped at its distal end with an expansion vessel able to absorb the expansions of said phase-change material as it changes phase.
