What are the key functions of the new energy vehicle battery thermal management system

1. Effectively dissipate heat when the battery temperature is high, and be wary of thermal runaway accidents; 2. Warm up when the battery temperature is low, increase the battery temperature, and ensure the charging and discharging performance and safety at low temperatures; 3. Reduce The temperature difference in the battery pack inhibits the formation of local hot spots, guards against the excessive rapid decaying of the battery at high temperature locations, and reduces the overall life of the battery pack. Accurate measurement and monitoring of battery temperature; effective heat dissipation when the battery pack temperature is too high; rapid heating under low temperature conditions; ensuring the even distribution of the battery pack temperature field; matching the battery heat dissipation system with other heat dissipation units is also an important function of battery thermal management . The heat-related issues of the battery are the key factors that determine its performance, safety, life and cost. The temperature level of the lithium battery directly affects its energy and power performance in use. When the temperature is low, the available capacity of the battery will rapidly decay. Charging the battery at too low temperature may cause instantaneous voltage overcharge. It causes internal lithium evolution and then causes a short circuit. As new energy vehicles begin to be used on a large scale, the performance of the battery system will receive more tests. From the current situation, to deal with the above problems, it is necessary to optimize the battery design system in combination with new materials. The optimization of system structure layout and control strategy can be adopted. An efficient and intelligent thermal management system will be the goal of future development, which is of vital significance to the safety of new energy vehicles.
