Problems solved by technology

[0007] In the case of a vehicle subjected to a rear impact, stress is observed to be transferred to the module assembly under the trunk floor, which tends to be lifted causing deformation of the cooling plate
The cooling plate may deteriorate, thus leading to a risk of overheating of the battery module, which may cause more serious problems

Embodiment Construction

[0025] figure 1 with figure 2 Shown is a floor 2 of an electric vehicle, comprising a front side indicated by arrows AV, receiving a rear electrical module block 4 arranged under the floor of the trunk of the vehicle, and a rear power module block 4 arranged in the driver's and front seats. The front power module block under the passenger's seat.

[0026] The two blocks of the rear block 4 and the front block 8 are respectively covered by shields. The rear block 4 is extended forwardly by a longitudinal protrusion 6 arranged along the center axis of the vehicle, allowing the two rear passengers to each place their feet on one side of the protrusion.

[0027] Therefore, the space utilization at the bottom of the cab is optimized in order to realize a large number of modules storing a certain amount of electrical energy.

[0028] The rear block 4 comprises a lower module layer 10 receiving above it a cooling plate 14 comprising a cooling fluid circulation. The forwardly pro...

Abstract

An electric or hybrid vehicle is equipped with a block of battery modules (10, 12, 16) arranged under the rear boot, this block comprising a lower layer of modules (10) receiving, on top, a cooling plate (14) in which cooling fluid flows, this lower layer (10), attached to a floor of the vehicle (2), extending in the middle of the vehicle via a protruding module (16) projecting from the block towards the front of the vehicle, this vehicle comprising a stiffening bridge (20) arranged in the transverse direction of the vehicle, passing over the protruding module (16), the ends of which are attached to the floor (2).

Description

technical field [0001] The present invention relates to an electric or hybrid vehicle equipped with a battery module disposed under a rear trunk. Background technique [0002] Hybrid or electric vehicles include electric battery module assemblies connected to each other by forming blocks, allowing storage of a certain amount of energy ensuring reduced fuel consumption of hybrid vehicles and ensuring range of electric vehicles. [0003] Battery modules are typically grouped together to form a substantially flat assembly that is positioned at the floor of the vehicle to limit the size of the assembly and lower the vehicle's center of gravity. [0004] One known type of motor vehicle, proposed in particular by document US-B1-9533600, comprises a module assembly forming a panel fastened under the floor of the vehicle, which floor is reinforced by longitudinal and cross members. The battery module is arranged on a cooling plate with water circulation to regulate the temperature ...
