Akkuhallintajärjestelmään, often abbreviated as BMS (Battery Management System), is a crucial electronic system that monitors and controls rechargeable battery packs. Its primary functions include protecting the battery from damage, optimizing its performance, and extending its lifespan. A BMS monitors key parameters such as voltage, current, and temperature for individual cells and the entire battery pack. It prevents overcharging and over-discharging, which can permanently damage battery cells and pose safety risks like thermal runaway.

The system also performs cell balancing, ensuring that all cells within a pack have similar charge levels. This is important because even small variations can lead to reduced overall capacity and premature aging. By actively managing the charging and discharging processes, a BMS ensures that the battery operates within its safe limits. Modern BMS units can also communicate with external devices, providing information about the battery's state of health, remaining capacity, and any detected faults. This data is vital for applications ranging from electric vehicles and portable electronics to large-scale energy storage systems. The complexity of a BMS can vary greatly depending on the battery chemistry and the application's requirements.
