Battery Management Systems (BMS)
Battery management systems (BMS) are critical components of electric car batteries, responsible for monitoring and controlling the battery’s performance, efficiency, and overall lifespan. The BMS is typically a computer-based system that monitors the battery’s state of charge, voltage, and temperature, and adjusts the charging and discharging processes accordingly.
The BMS also provides protection against overcharging, over-discharging, and overheating, which can damage the battery and reduce its lifespan. Some common features of BMS include charge balancing, cell monitoring, and thermal management.
Thermal Management Systems
Thermal management systems are critical components of electric car batteries, responsible for regulating the battery’s temperature and preventing overheating. The thermal management system typically consists of a combination of cooling and heating elements, including heat exchangers, fans, and thermal interfaces.
