An automotive battery management system is a system designed to control the safe operation of on-board lithium-ion batteries installed in vehicles such as electric vehicles (EVs) and hybrid cars.
Generally, systems that manage the safety of secondary batteries such as lithium-ion batteries are referred to as Battery Management Systems (BMS). The automotive battery management system is a specialized system within BMS tailored for on-board vehicle batteries. While lithium-ion batteries offer high efficiency and energy density, they also pose risks such as fire or smoke, necessitating precise control. Using an automotive battery management system enables safe and efficient battery operation.
The primary purpose of an automotive battery management system is to control vehicle batteries effectively, enhancing safety and performance. Additionally, it is expected to extend battery life through proper battery usage.
The main vehicles where automotive battery management systems are used include:
The automotive battery management system monitors and controls the charging and discharging of batteries through electronic control circuits. Specific monitoring parameters include:
Additionally, one of the roles of the battery management system is to prevent excessive stress on batteries. It includes features to prevent overcharging, over-discharging, and overcurrent in cells (individual battery cells within battery modules), caused by extreme rapid charging or high discharging currents.
The main functions of an automotive battery management system include:
The automotive battery management system measures the voltage, current, and temperature of cells (individual battery cells) within battery modules. If any parameter exceeds set limits, it disconnects output terminals to protect against overcharging, over-discharging, or overcurrent situations, thus controlling power supply based on battery capacity.
Furthermore, it balances cell voltages (cell balancing) to ensure that different battery cells within a battery pack maintain similar charge/discharge requirements.
The automotive battery management system comprises the following components:
Electronic components used include:
Automotive battery management systems vary based on vehicle types such as Hybrid Electric Vehicles (HEVs), Plug-in Hybrid Electric Vehicles (PHEVs), Battery Electric Vehicles (BEVs), etc. It is essential to select the system based on vehicle type and other factors like the number of monitorable cells, battery voltage type (e.g., 12-24V or 48V), and voltage control precision. Specifically, high-voltage battery systems are appropriate for vehicles using high-voltage batteries.
