In the lithium-ion battery pack, there are the main electronic modules: the batteries (cells) connected in groups in parallel and series, the cell contact system, and the BMS (battery management system). The BMS is the brain of the battery pack. . BMS (Battery Management System): Monitors cell voltages, current, and temperature; prevents overcharge, deep discharge, and thermal abuse; balances cells for longevity. Knowing what each of these parts means is important if you design, make, or use things that run on batteries. The battery management system monitors the batteries' temperatures and voltages. . A BMS for lithium-ion batteries acts as the "brain" of the battery pack, continuously monitoring, protecting, and optimizing performance to ensure safe operation and maximum lifespan.
