BTMS Battery Thermal Management System The Battery Thermal Management System is a complete thermal system solution that maintains the critical operating temperature range of automotive batteries. Design solutions are available for both active and passive cooling circuits. Function The function of the battery thermal management system is to regulate the temperature of the battery in real time to maintain the battery working in the optimal temperature range to ensure the performance, life and safety of the battery. It is mainly categorized into the following situations. 1ã??Preventing overheating: When the battery temperature is too high, the battery performance will be affected and may even fail. The battery thermal management system can reduce the battery temperature in time through heat dissipation and other methods to prevent the battery from overheating. 2, to prevent overcooling: in a low-temperature environment, the battery performance will also be affected, and even can not work properly. Battery thermal management system can raise the battery temperature in time through heating and other methods to prevent the battery from overcooling. 3, to maintain the stability of the battery temperature: in the vehicle driving process, the battery temperature will continue to change, if the temperature fluctuation is too large, will have a negative impact on the battery performance. Battery thermal management system can control the coolant flow and other methods to keep the battery temperature stable. 4, improve battery life: by controlling the battery temperature within the optimal range, you can extend battery life. Reduce the number of replacements and lower maintenance costs.
