Problems solved by technology

Disadvantageously, the concept of direct cooling of battery cells cannot be easily transferred to liquid cooling liquids, and direct cooling of liquid cooling liquids has hitherto only been realized in individual areas of the battery cells, such as the shunts of the battery cells

Embodiment Construction

[0023] figure 1 A cross-sectional view of a storage battery device 1 for a hybrid or electric vehicle according to the present invention is shown. The storage battery device 1 has a battery block of a plurality of battery cells 3 stacked on top of each other in the X direction. The battery block 2 then has a first contact side 4a and a second contact side 4b; a first support side 5a and a second support side 5b; and two clamping sides 6a and 6b (see in this respect image 3 ). The contact sides 4a and 4b are arranged opposite to each other in the Y direction perpendicular to the X direction, and the support sides 5a and 5b are arranged opposite to each other in the Z direction perpendicular to the X direction and the Y direction. The clamping sides 6 a and 6 b are arranged opposite to each other in the X direction. Furthermore, the rechargeable battery device 1 has a housing 7 which has a component interior 8 in which the battery blocks 2 are arranged. The battery cells 3 ...

Abstract

The invention relates to an accumulator arrangement for a hybrid or electric vehicle. The accumulator arrangement includes a plurality of battery cells stacked in an X direction to form at least one battery block, having two opposite contact sides in a Y direction, two opposite support sides in a Z direction, and two opposite clamping sides in an X direction. In addition, the accumulator arrangement includes a housing with at least one part interior in which at least one battery block is arranged. The accumulator arrangement further includes a cooling device, a cooling fluid being flowable through the cooling device for cooling the battery cells in the at least one battery block. According to the invention, at least one battery block in the corresponding part interior may be able to be flowed around by the cooling fluid multilaterally, or flowed around by the cooling fluid multilaterally and flowed through at least partially, so that the part interior forms a part of the cooling devicethrough which the cooling fluid is flowable.

Description

technical field [0001] The invention relates to a battery arrangement for a hybrid or electric vehicle according to the preamble of claim 1 . Background technique [0002] Battery arrangements for hybrid or electric vehicles are known from the prior art. Here, a plurality of battery cells are accommodated in the battery module and arranged in the case. In order to realize the function of the battery module, the battery cells are temperature-controlled here. Especially in battery installations with high power density and the required fast charging capability, efficient cooling is essential. A battery arrangement with direct air cooling is known from WO 2017 / 026312 A1. Here, air flows directly around the battery cells and thus cools the battery cells. Since air has a relatively low heat-absorbing capacity, a large air flow must be directed against the contact surface. Here, the air is distributed randomly in the housing or is guided in so-called circular paths around the ...
