Embodiment Construction

[0016] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as representative basis for teaching one skilled in the art to variously employ the present invention.

[0017] Such as figure 1 As shown, a battery pack according to an embodiment of the present invention includes a housing formed from a base 10 and a cover 12, wherein the cover 12 is shown removed to expose the interior of the battery pack. The interior of the battery pack can be divided into an electronics section 14 and a battery cell section 16 . The battery pack is suitable for use...

Abstract

The invention provides a battery pack and a casing used for the battery pack. One type of battery pack that may be used in electrically driven vehicles includes a first array of battery cells and a second array of battery cells disposed adjacent to each other and a housing surrounding the two arrays. The housing defines: a cooling chamber that surrounds the heat transfer surfaces of the battery cells; a first manifold that is isolated from the cooling chamber and collects gas generated by the first array; a second manifold that is isolated from the cooling chamber and collects gases generated by the second array. Gas generated by the array. A channel connects the first and second manifolds to allow any gas collected from the first manifold to pass into the second manifold, and a vent in the second manifold allows the collected gases to escape from the housing. out. Conductive bridge bars extend through the channels and connect the first array with the second array.

Description

technical field [0001] The invention relates to a battery pack of the type used in motor vehicles driven by high voltage electric motors. Background technique [0002] Depending on the type of power source (eg, involving a chemical reaction) such as a battery cell or battery pack, the power source may emit a certain amount of gas during its operating life. In certain applications (eg, when the battery pack is used in a vehicle) it may be desirable to provide a ventilation system to allow such by-product gases to escape from the power source. To ventilate battery cells and packs carried on wheeled motor vehicles such as cars, trucks, vans, SUVs, construction vehicles, etc., complex systems can be required to capture the by-product gases and remove them from the vehicle. discharge. Adding to the challenge of this design is that in systems with multiple cells in stacks or arrays, the tolerance stack-up of the cell to its neighbors may make it difficult to provide robustness t...
