Abstract

The invention relates to a battery and discloses a power battery module with a liquid cooling system. The power battery module is characterized in that a battery pack [2] is installed in a battery module shell [1], a coolant inflow pipe [3] and a coolant outflow pipe [4] are arranged on one side of the battery pack [2], and the coolant inflow pipe [3] is connected with a pressure pump through a coolant inlet [5]; the coolant outflow pipe [4] is connected with a heat exchanger through a coolant outlet [6]; and a radiating fin is installed on each monomer battery of the battery pack [2], and a radiating flow passage is arranged in the radiating fin and is connected with the coolant inflow pipe [3] and the coolant outflow pipe [4] through liquid-coolant parts. The power battery module with the liquid cooling system has the beneficial effects that the problems of complex process, high manufacturing cost, inconspicuous cooling effect and the like of the prior art are solved, the dimension of the battery pack is reduced, the manufacturing process is simplified, the manufacturing cost is saved, the radiating efficiency is high and the like.

Description

technical field [0001] The present invention relates to batteries, in particular to power battery modules for electric vehicles and hybrid vehicles. Background technique [0002] Secondary batteries used as power sources for electric vehicles (EV) and hybrid electric vehicles (HEV) must have high output and large capacity characteristics. Therefore, multiple small secondary batteries are connected in series or in parallel to form a battery modules, and multiple battery modules are connected in series or in parallel to form a battery pack. Due to the high energy density stored in secondary battery cells and the compact arrangement of modules, a large amount of heat that is not easy to dissipate is generated during the working process, resulting in attenuation of battery performance and reduced safety. Therefore, it is necessary to provide a cooling Cooling system for high output high capacity battery pack. [0003] In recent years, air-cooled heat dissipation methods have b...
