What is Battery Management System (BMS)?

The brain of the battery — monitors and protects every cell.

BMS is an electronic system that monitors battery voltage, temperature, and state of charge at cell level. It prevents overcharging, over-discharging, and overheating — the three biggest risks to battery health. BMS is why modern EVs are very safe and why batteries last 10+ years.
