Abstract

A battery for powering an electrical motor drive of a motor vehicle includes electrochemical accumulators included in an adiabatic enclosure and included in a tightly-sealed enclosure. The tightly-sealed enclosure is air-tight and water-tight, contains the adiabatic enclosure, and has a volume that is external to the adiabatic enclosure and benefits from thermal exchanges with an exterior thereof. The battery also includes a valve that selectively sets up a flow of a heat-transfer fluid between the adiabatic enclosure and the volume.
