BMS for Lithium-Ion Batteries: The Essential Guide to Battery
Unlike simpler protection circuit modules (PCMs), a comprehensive BMS offers advanced features including cell balancing, thermal management, communication capabilities,
From real-time monitoring and cell balancing to thermal management and fault detection, a BMS plays a vital role in extending battery life and improving overall performance. As the demand for electric vehicles (EVs), energy storage systems (ESS), and renewable energy solutions grows, BMS technology will continue evolving.
The battery management system is an electronic system that controls and protects a rechargeable battery to guarantee its best performance, longevity, and safety. The BMS tracks the battery's condition, generates secondary data, and generates critical information reports.
One of the key functions of a BMS is cell balancing, which ensures that each cell in a battery pack is charged and discharged uniformly. Cells in series often exhibit slight differences in capacity, causing certain cells to overcharge or undercharge.
The battery functions as the primary power source in EVs. Because of its great importance, each cell in the pack needs to function at its best. A battery that is not properly maintained may overheat, lose its balance, degrade more quickly, or even provide safety risks such as thermal runaway. Consequently, the BMS of an EV is required to:
