A Battery Thermal Management System (BTMS) is a comprehensive technology system for monitoring, regulating, and controlling the temperature of a power battery pack. Its core mission is to ensure that the battery always operates within its safe and efficient optimal temperature range under any external environment, and to maintain uniform temperature across all battery cells.
Simply put, BTMS is like a"smart temperature manager"for electric vehicle batteries-it prevents the battery from overheating or freezing, keeping it in optimal operating condition at all times.
