Abstract

The invention discloses a battery module assembly, which comprises battery modules and conducting strips, wherein the conducting strips are used for leading out positive electrodes and negative electrodes of the battery modules; the conducting strips are arranged at end parts of the battery modules; the battery module assembly also comprises heat exchange plates; the heat exchange plates are provided with heat exchange passages capable of circulating heat exchange mediums; the heat exchange passages are provided with inlets and outlets; the heat exchange plates and the conducting strips are arranged in parallel along a longitudinal direction of the battery modules and further make contact in a heat conduction manner. In the battery module assembly, the heat exchange plates are correspondingly arranged for the conducting strips; the temperature drop or the temperature rise can be carried out on the heat exchange plates through the heat exchange mediums circulated on the heat exchange plates; further, the temperature drop or the temperature rise can be carried out on the battery module through the heat exchange plates and therefore, the battery module assembly can be used for effectively solving the problem that a battery module assembly is poor in heat radiation effect.

Description

technical field [0001] The present invention relates to the technical field of power supply, and more specifically, relates to a battery module. Background technique [0002] When the power battery is charged and discharged at a high rate, it will generate high heat, which will cause the temperature of the battery to rise sharply in a short time. If the battery temperature is too high, it will affect the cycle life of the battery, the acceptability of charge and discharge, the performance of the battery, and the temperature of the battery. Uniformity, etc., and the battery temperature is too high to be potentially dangerous, which may cause safety problems. The thermal management control of the power battery pack is very important, and it is an important guarantee to ensure the reliable and safe operation of electric vehicles. When the battery is used at low temperature, due to the low ambient temperature and low chemical reaction activity of the battery, it is very difficu...
