Solar container lithium battery protection board process

The protection process depends on the coordination of control IC + MOSFETs + sensing circuits. This is where the lithium battery protection board—often referred to as a PCM (Protection Circuit Module) or part of a Battery Management System (BMS)—plays a crucial safety, stability, and longevity role. From an engineering perspective, it acts as the first line of defense against electrical. In the last article, we introduced the comprehensive technical knowledge about lithium-ion cell, here we begin to further introduce the lithium battery protection board and BMS technical knowledge. Overcharge/Over-discharge Prevention: Like a vigilant lifeguard, it stops charging at 95% capacity to avoid lithium plating. Temperature Regulation: Maintains optimal thermal conditions (±2°C accuracy in advanced designs).
