Liquid-cooled battery module

Abstract

The invention discloses a liquid-cooled battery module, which comprises a liquid-cooled plate, the liquid-cooled plate is arranged on the outer side surface of the whole battery module, one side, far away from the battery module, of the liquid-cooled plate is connected with a fixed ribbon, one side, close to the battery module, of the liquid-cooled plate is provided with a plurality of battery cells, and the plurality of battery cells are electrically connected to a plurality of aluminum bars. According to the liquid-cooled battery module disclosed by the invention, an original bottom liquid-cooled mode is cancelled, and the liquid-cooled plate is fixed on the outer side edge of the battery module and is fixed by using the fixing ribbon, so that compared with the condition that the liquid-cooled plate is arranged at the bottom of the module, the height size of a battery pack can be obviously reduced, and the height space of a whole vehicle is greatly saved while the heat dissipation effect is ensured.

Description

Technical field [0001] The present invention relates to the field of electric vehicle technology, in particular a liquid-cooled battery module. Background [0002] In the field of electric vehicles, battery packs are usually composed of several modules and boxes, high and low voltage wiring harnesses, BMS and other components, and the modules are composed of batteries, wiring harnesses, aluminum bars, end plates, fixed cable ties, upper covers, etc. The existing scheme for heat dissipation of the battery cell is to arrange the liquid cold plate on the bottom plate of the box body, and the module is placed on the liquid cold plate, so that the liquid cold plate is in contact with the bottom of the module, thus achieving the purpose of cooling / heating the battery cell. Because the module liquid cold plate of the prior art is designed at the bottom of the module, it is more difficult to reduce the height of the battery pack, because the battery pack height (thickness) direction size...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the problem that it is difficult to reduce the height of the battery pack at the bottom of the module in the prior art, and proposes a liquid-cooled battery module that cancels the original bottom liquid-cooled mode. The liquid cold plate is fixed on the outer side and fixed with a fixed cable tie, which can significantly reduce the height of the battery pack compared to the case where the liquid cold plate is arranged at the bottom of the module, while ensuring the heat dissipation effect, it greatly saves the entire battery pack. car height space
