A Battery Management System (BMS) is an essential electronic control unit (ECU) in electric vehicles that ensures the safe and efficient operation of the battery pack. It acts as the brain of the battery, continuously monitoring its performance, managing its charging, and discharging cycles, and protecting it from various hazards.
It ensures optimal battery utilization by controlling the battery’s state of charge (SoC), state of health (SoH), and maintaining safety during charge and discharge cycles. In modern electric vehicles (EVs), Battery Management System plays a crucial role in ensuring efficient energy use and prolonging battery life.
The communication interface allows the BMS to exchange information with external devices, such as an on-board computer or charger. This interface could use CAN, UART, or other communication protocols to relay critical battery information and receive commands. Fig 1 Key Functionalities of a Battery Management System (BMS) 3.
Battery management systems seamlessly integrate with EV chargers to ensure safe and efficient energy distribution. Many popular EVs use one of four primary BMS architectures: centralized, distributed, modular, or hybrid. Evolving technologies, such as AI/ML and wireless BMS, are paving the way for new advancements in battery management.
d. Battery Control Unit (BCU) The BCU is the brain of the BMS. It collects data from all other components and makes decisions about charging, discharging, balancing, and protecting the battery pack. It communicates with the vehicle’s central control system to provide real-time information about the battery’s status.
This includes optimizing acceleration and regenerative braking, and preventing thermal runaway. Smart battery packs, particularly the more advanced ones, incorporate embedded chargers to expedite rapid charging, with the BMS managing the process for wired and wireless systems.
