The protection features available in the Battery Management System are listed below. When a lithium battery is charged beyond a safe charging voltage, the cell heats up extremely and its health is affected and its life cycle and current carrying capacity get reduced.
A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. Over-charge: is when the battery is charged over the allowed maximum capacity. High & low temperature: is when the internal temperature of the battery cells exceeds their safe operational temperature ranges.
The Gate of the right pair of MOSFETs which are responsible for protecting the battery pack from overcharging is connected to the positive terminal of the battery pack. When the battery is overcharged, the DW01 IC will sense the overcharge condition using the internal potential divider circuit and will turn on the OD transistor.
Over-discharging can significantly reduce a battery’s capacity, lowering the voltage below safe levels (typically around 2.7V for lithium-ion cells). PCMs prevent over-discharge by cutting off the circuit when the voltage drops too low, preserving the battery’s health and prolonging its operational life.
Protection Circuit Modules enhance battery safety by monitoring and controlling critical parameters such as voltage, current, and temperature. They prevent overcharging, over-discharging, and short circuits, ensuring the battery operates within safe limits and protecting both the battery and the device from potential hazards. 2.
It is an electronic device that can monitor and manage the battery. It can control the charging and discharging process of the battery by collecting and calculating the voltage, current, temperature and SOC of the storage, so as to realize the protection of the battery and improve the comprehensive performance of the battery.
