What is a Battery Management System (BMS)? –
There are many BMS design features, with battery pack protection management and capacity management being two essential features.
A BMS monitors the temperatures across the pack, and open and closes various valves to maintain the temperature of the overall battery within a narrow temperature range to ensure optimal battery performance. Capacity Management Maximizing a battery pack capacity is arguably one of the most vital battery performance features that a BMS provides.
A BMS's control and management operations are built on top of monitoring. It is essential to continuously monitor important variables including voltage, current, temperature, and SOC. Each cell or group of cells in the battery pack is continuously monitored by the BMS to make sure they are operating within the specified parameters.
Safety represents the primary driver behind BMS requirements in most applications, as modern lithium-ion batteries store tremendous amounts of energy in compact packages. Beyond safety considerations, battery management systems provide significant performance benefits that justify their implementation.
The BMS collects data such as voltage, temperature, current, and state of charge. This data is vital for system diagnostics and performance optimization. The BMS may communicate with other devices, such as vehicle controllers or cloud-based systems, to relay real-time information about the battery's condition and performance.
