Abstract

The invention relates to the technical field of battery modules, and discloses a battery monomer and a battery module, wherein the battery monomer comprises a battery cell and a shell, and a positive tab and a negative tab are arranged on one surface of the battery cell; one end of the shell is provided with an opening, the shell sleeves the periphery of the battery cell, and the positive tab and the negative tab are located at one end of the opening; the inner wall of the shell is provided with a cooling pipeline, the cooling pipeline is attached to the outer wall of the battery cell, one end of the cooling pipeline is a water inlet, and the other end of the cooling pipeline is a water outlet. According to the invention, the cooling channel is arranged on the shell, so that the battery monomer has a thermal management function, and the thermal management efficiency is high aiming at the single battery cell; in addition, the battery monomer is simple in structure, reliable in work and long in service life.

Description

technical field [0001] The invention relates to the technical field of battery modules, in particular to a battery cell and a battery module. Background technique [0002] The heat-related problems of electric vehicle batteries are the key factors that determine their performance, safety, life and cost. Because the battery itself has a certain internal resistance, it generates a certain amount of heat while outputting power and electric energy, which increases the temperature of the battery. When the battery temperature exceeds its normal operating temperature range, it will affect the life of the battery. [0003] In the prior art, in order to ensure that the battery works at an appropriate temperature, a thermal management system is usually provided outside the battery module. On the one hand, the thermal management system installed outside the battery module has many components, which increases the risk of use; on the other hand, it cannot perform independent thermal man...
