Battery Management ICs (BMICs) are specialized chips for overseeing battery systems. Their key aim is to guarantee batteries operate safely and efficiently, prolonging battery lifespan.
BMICs have multiple functions. They monitor battery state by tracking voltage, current, and temperature. This helps detect over – charge, over – discharge, and temperature issues. In charging control, they manage different modes like CC and CV, and precisely end charging. For protection, BMICs prevent over – charge, over – discharge, and over – current situations. They also estimate battery capacity, predicting remaining charge and assessing health status, which is useful for users to know battery’s usability and when to replace it.
