Abstract

A device for cooling and/or heating a battery of an electric or hybrid motor vehicle, including a battery box provided with: at least one envelope of a composition including between 0 and 80 wt. %, in relation to the total weight of the composition, of reinforcing fibres, between 0 and 20 wt. %, in relation to the total weight, of at least one thermoconductive component, between 0 and 20 wt. %, in relation to the total weight, of at least one impact modifier, and between 0 and 20 wt. %, in relation to the total weight of the composition, of additives, the remainder being a matrix predominantly including at least one polyamide and optionally at least one flameproofing agent; an inlet for a heat-transfer fluid; and an outlet for a heat-transfer fluid, the box defining a battery cooling and/or heating space.

Claims5

Dependent claims

A cooling and/or heating device for an electric or hybrid motor vehicle battery comprising:

a battery box provided with only a single enveloping layer, which is an outer envelope made up of a composition comprising:
20 to 80% by weight in relation to the total weight of the composition of reinforcing fibers which do not have thermally conducting properties;
0 to 20% by weight in relation to the total weight of at least one thermoconductive component;
0 to 20% by weight in relation to the total weight of at least one impact modifier;
and
0 to 20% by weight in relation to the total weight of the composition of additives,
wherein the remainder of the outer envelope is a matrix comprising at least one polyamide and at least one flameproofing agent,
wherein the outer envelope has a thermal conductivity between 1 and 0.1 W/mK;
a heat transfer fluid inlet;
and
a heat transfer fluid outlet,
wherein the battery box delimits a cooling and/or heating volume for the electric or hybrid motor vehicle battery,
wherein the cooling and/or heating device is configured to utilize liquid heat transfer fluid.
