## Abstract

A battery comprises: at least one electrical energy storage cell; an enclosure in which the at least one electrical energy storage cell is housed, the enclosure having a bottom made from a material with low thermal conductivity having at least one flow channel for a cooling fluid; a thermal plate made from a material with a high thermal conductivity, laying down on the bottom the thermal plate being in thermal contact with the at least one electrical energy storage cell; and a cradle, facing the bottom and separated from the bottom by a space.

## Claims

### Claim 1

A battery, comprising:
at least one electrical energy storage cell;
an enclosure in which the at least one electrical energy storage cell is housed, the enclosure having a bottom made from a material with a low thermal conductivity having at least one flow channel for a cooling fluid;
a thermal plate made from a material with a high thermal conductivity, laying down on the bottom, the thermal plate being in thermal contact with the at least one electrical energy storage cell; and
a cradle, facing the bottom and separated from the bottom by a space.

### Claim 2 (depends on 1)

The battery of claim 1, wherein the bottom is made from a composite or plastic material.

### Claim 3 (depends on 2)

The battery of claim 2, wherein the composite material comprises a thermoplastic or thermosetting material and a reinforcement, the reinforcement comprising fibers, a majority of the fibers being short fibers with a length smaller than about 51 mm.

### Claim 4 (depends on 1)

The battery of claim 1, wherein the bottom has an inner face facing the thermal plate and an outer face facing the cradle, the inner face bearing reliefs delimiting the at least one flow channel between them.

### Claim 5 (depends on 4)

The battery of claim 4, wherein the at least one flow channel is open toward the thermal plate.

### Claim 6 (depends on 5)

The battery of claim 5, wherein the thermal plate is laying down on the reliefs and closes the at least one flow channel.

### Claim 7 (depends on 1)

The battery of claim 1, wherein the cradle is made from a composite material.

### Claim 8 (depends on 7)

The battery of claim 7, wherein the composite material comprises a thermoplastic or thermosetting material and a reinforcement, the reinforcement comprising fibers, a majority of the fibers being continuous fibers with a length greater than about 100 mm.

### Claim 9 (depends on 1)

The battery of claim 1, wherein the enclosure comprises an upper part fastened tightly to the bottom.

### Claim 10 (depends on 1)

The battery of claim 1, wherein the bottom is connected to the cradle at a plurality of points distributed over a surface of the bottom.

### Claim 11 (depends on 1)

A vehicle comprising a body and a battery according to claim 1, the cradle being fastened directly to the body.
