To maximize the lifespan, performance, and safety of a lithium-ion battery, the charging process must be strictly controlled. As a battery discharges, its working voltage decreases. To properly restore this energy without damaging the cell’s internal chemistry, modern lithium battery chargers and Battery Management Systems (BMS) utilize a precise, IC-chip-controlled charging algorithm. This standard charging […]
