Embodiment Construction

[0022] First reference figure 2 and image 3 , Usually use B2 to indicate the detachable battery module, which can be used to modular battery systems (such as the above reference) figure 1 The modular battery system described is described. As already explained above, the battery module B2 can be mounted on the vehicle by insertion along a given direction (preferably horizontal direction (especially longitudinal or lateral direction), and can be taken out in a direction opposite to the insertion direction. Remove from the vehicle.

[0023] The battery module B2 first includes an outer housing 10 and one or more (rechargeable) battery packs 12 housed inside the housing 10. In the embodiment shown in the drawings, the battery module B2 includes two battery pack 12, but of course, different number of battery packs can be provided.

[0024] The battery pack 12 is arranged to contact with the first heat conducting plate 14 (hereinafter referred to as "first board") that is also accommoda...

Abstract

In order to allow cooling of the battery packs (12) of a removable battery module (B2) of a modular battery system of an electric or hybrid motor-vehicle (V), the removable battery module (B2) comprises an outer casing (10), a first thermally conductive plate (14) which is received inside said casing (10) and on which the battery packs (12) are arranged, an internal circuit which extends inside the first plate (14) and is filled with a heat transfer fluid, and a second thermally conductive plate (22) which is fluidly connected to this internal circuit so as to be flowed through by the heat transfer fluid flowing in this internal circuit and is arranged with an outer face thereof (22a) outside the casing (10) to be placed in contact with a direct expansion plate (26) of an auxiliary cooling circuit (28) installed on the motor- vehicle (V).

Description

Technical field [0001] The present invention generally relates to a motor vehicle having an electric or hybrid driving force, and more particularly to a motor vehicle having a modular battery system. Background technique [0002] It is well known that the high cost of electric or hybrid vehicles is mainly due to the high cost of the battery unit. In order to overcome this disadvantage, a modular battery system has been introduced, including one or more fixed battery modules and one or more additional battery modules that can be installed or unloaded as needed. [0003] Attached figure 1 A bottom view showing an electric or hybrid vehicle in an overall v-instruction, the electric or hybrid vehicle is provided with: including a plurality of rechargeable battery modules B1 and B2 power supply assemblies, the power supply assembly located on the vehicle floor. Suitable receiving space, a power propulsion system for supplying a vehicle; and a battery management system BMS, battery mod...
