Abstract

The invention belongs to the technical field of power batteries, and particularly relates to an energy storage liquid-cooled battery pack. The battery pack comprises a bottom liquid cooling plate and a plurality of battery modules arranged on the bottom liquid cooling plate, and the plurality of battery modules are bound together through a fixing belt; a side liquid cooling plate is arranged in each battery module, and a plurality of side liquid cooling plates are connected in parallel. The battery module comprises a plurality of battery cells, and the plurality of battery cells are arranged on the two sides of the side liquid cooling plate respectively; and the plurality of battery cells are sequentially connected in series through the connecting bar. The bottom liquid cooling plate is used for main heat dissipation, the side liquid cooling plates play a role in temperature equalization, the temperature difference between the upper part and the lower part of the battery pack is obviously reduced, the temperature consistency of the battery pack is improved, and the energy density of the battery pack is improved, so that the purpose of high-rate operation is achieved.

Description

technical field [0001] The invention belongs to the technical field of power batteries, in particular to an energy storage liquid-cooled battery pack. Background technique [0002] With the rapid development of the economy, the demand for electricity in all walks of life is increasing. At present, the development of container-type energy storage products is becoming more and more mature, and there is an urgent need to increase the energy density of container-type energy storage. Liquid cooling can not only improve the energy density of container-type energy storage, but also ensure the temperature consistency of battery packs. [0003] In the prior art, energy storage battery packs are mostly air-cooled. Due to physical parameters such as air’s low specific heat capacity, low density, and poor thermal conductivity, the air-cooled temperature consistency is poor; traditional battery packs also use liquid cooling to dissipate heat. It is based on the technical solution of the...
