Abstract

The invention discloses a liquid-cooled battery module. The liquid-cooled battery module comprises a battery module (100), wherein the battery module (100) comprises a plurality of battery cells (8) which are longitudinally arranged in parallel; the cross section of each battery cell (8) is rectangular; two L-shaped heat conducting tubes (11) are arranged outside the battery module (100) and are distributed in a central symmetry manner; a structure capable of transferring heat is arranged between each heat conducting tube (11) and the battery module (100); each heat conducting tube (11) makescontact with one liquid-cooled plate (6). The liquid-cooled battery module disclosed by the invention has the advantages that the performance is excellent; the temperature in the battery module can bereduced; the problem of heat dissipation of the battery cells in the battery module is well solved; use safe risk of the battery module is remarkably reduced, industry scale can be formed, and wide application is facilitated; the liquid-cooled battery module has great production and practical significance.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a liquid-cooled battery module. Background technique [0002] At present, the existing electric vehicle industry has higher and higher requirements for energy density, and the size of battery cells is also increasing. It is required to arrange as many battery cells as possible in a limited installation space to improve The cruising range of electric vehicles; at the same time, electric vehicles also require that the charging rate of battery cells should be guaranteed to be at least 1C. Therefore, in the case of reducing the gap between adjacent battery cells and increasing the charge and discharge rate at the same time, how to ensure that the temperature of the battery module (that is, the battery pack) after the increase is within the working range of the battery cells becomes a driving force. Batteries and even the entire electric vehicle industry. [0003] In order to effe...
