What are the important components of the new energy vehicle battery thermal management system

The important task of the battery management system is to ensure that the battery pack works within a safe interval, provide necessary information for vehicle control, respond to and solve abnormalities in time, and determine the charge and discharge of the battery according to the ambient temperature, battery status, and vehicle requirements. Power, etc. The important functions of BMS include battery parameter monitoring, battery state estimation, online fault diagnosis, charging control, automatic equalization, thermal management, etc. The new energy vehicle battery thermal management system is mainly composed of heat conduction medium, measurement and control unit and temperature control equipment. After the heat-conducting medium contacts the battery pack, the heat generated in the battery system is dissipated to the external environment through the flow of the medium. The heat-conducting medium mainly includes air, liquid, and phase change materials. The measurement and control unit controls the temperature control equipment to perform corresponding thermal solutions by measuring the real-time temperature of the battery system and the battery module or even the different positions of the monomer. The thermal management system is one of the key technologies to deal with battery heat-related issues and ensure the performance, safety and life of power lithium-ion batteries. On the one hand, it can absorb the swelling stress of the battery for buffering purposes, and on the other hand, it can play a role in heat insulation. , In the case of thermal runaway of the battery cell, the thermal diffusion is suppressed and the accident is delayed. To solve the thermal insulation between square cells, some companies have already adopted aerogels, which are quite safe, but there is a very real cost problem.
