Problems solved by technology

Because the power battery of an electric vehicle will generate a lot of heat during high-power charging and discharging, if the accumulated heat cannot be exported in time, the temperature of the battery module will rise sharply, affecting the charging and discharging efficiency of the battery and shortening the battery life. The life of the module, even spontaneous combustion in severe cases
[0005] In addition, in high latitude areas, in the cold winter, the battery module cannot reach the normal charging and discharging operating temperature due to the low temperature, resulting in smaller storage capacity of the battery module, lower charging and discharging power, and shorter battery life.
[0006] At present, the cooling or heating of the battery module is usually realized by a liquid-cooled heating device. Although this method can locally cool the battery module, it will cause the temperature of the battery cells in the battery module to be inconsistent, which will make the temperature of each battery The current of the unit is inconsistent, and the current inconsistent for a long time will affect the life of the battery module

Abstract

The invention provides a battery module. The battery module comprises a plurality of battery units arranged side by side, two end plates respectively butted against two ends of the battery units and two side plates butted against two sides of the battery units. Each side plate comprises a substrate and a plurality of heat conducting plates vertically connected to the surface of one side of the substrate, wherein the substrate is internally provided with a heat conducting pipe, the heat conducting plates are arranged at intervals, and each heat conducting plate is clamped between each two adjacent battery units. The battery module provided by the invention has the advantages of the stable structure, the good battery temperature consistency and the good heating and refrigerating effect.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of power batteries, in particular to a battery module. [0003] 【Background technique】 [0004] With the development and progress of new energy technology and the vigorous promotion and popularization of the government, new energy power batteries are more and more used in various fields of life, especially in the field of electric vehicles. Because the power battery of an electric vehicle will generate a lot of heat during high-power charging and discharging, if the accumulated heat cannot be exported in time, the temperature of the battery module will rise sharply, affecting the charging and discharging efficiency of the battery and shortening the battery life. The life of the module, even spontaneous combustion occurs in severe cases. [0005] In addition, in high latitude areas, in the cold winter, the battery module cannot reach the normal charging and discharging operating temperature due to the low temp...
