Embodiment Construction

[0014] Figure 1a and 1b A battery pack 1 for a vehicle of this type is shown in a perspective view and a view from above, respectively. The battery pack 1 is basically formed by an aluminum base 2 sealed by a cover 3, also made of aluminium. The base 2 includes two valves 9 for maintaining the pressure balance between the battery pack 1 and the outside. The battery pack 1 contains all the elements necessary for the storage of electrical energy, i.e. two modules of 24 interconnected electrochemical cells and all the elements required to connect them to the traction circuit of the vehicle, none of which are in the shown in the figure. The battery pack 1 also contains electronic control and safety components, notably a battery management system (BMS). According to the invention, a first port 4 is located on top of the cover 3 thus providing access to the interior of the battery pack 1 for introducing a pressurized fire extinguishing fluid (eg water) into the battery pack 1 . ...

Abstract

The present invention relates to an electric or hybrid vehicle comprising an arrangement of means for introducing an extinguishing fluid into a battery pack, especially a drive battery, of said vehicle. A first flap is placed in a wall of the pack and provides access to the interior of the pack, this flap comprising partial or total blocking means, these means being removable or meltable under the effect of temperature. A second flap is placed in an element of the body of the vehicle facing the first flap. Thus, the extinguishing fluid may be introduced into the pack through the two flaps once the blocking means of the first flap have been removed or melted. Application: drive batteries.

Description

technical field [0001] The invention relates to a vehicle having an arrangement with devices enabling firefighters to prime the traction battery of said vehicle, in particular with a fire extinguishing fluid such as water. In particular, but not exclusively, the invention is applicable to lithium-ion (Li-ion) batteries that power the power train of an electric or hybrid vehicle. Background technique [0002] Li-ion batteries are particularly suitable for powering the power train of an electric or hybrid vehicle due to their high voltage and their high energy density. In this type of battery, the Li-ion cell is an essential component that contains a quantity of electrolyte, which can be a solid or liquid electrolyte, through which lithium ions can migrate between the cathode and anode for storage or transfer electrical energy. Multiple Li-ion cells are first assembled and connected in series and / or parallel to form a module, then multiple modules are assembled and connected...
