The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
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.
Fig. 1 is a block diagram of circuitry in a typical Li-ion battery pack. It shows an example of a safety protection circuit for the Li-ion cells and a gas gauge (capacity measuring device). The safety circuitry includes a Li-ion protector that controls back-to-back FET switches. These switches can be
The protection circuit block diagram is given below. This is a High side protection circuit. The battery configuration is S4 (four in series), and a fuse is connected to the positive side of the battery to shut off the battery when the current exceeds the limits. There is BMS Monitoring every cell voltage for balancing and fault detection.
Battery protection circuits / IC solutions and reference designs that allow easy design-in and ensure safe charging and discharging - prevent damage and failures.
This combination of cells is called a battery. Sometimes battery packs are used in both configurations together to get the desired voltage and high capacity. This configuration is found in the laptop battery, which has four Li-ion cells of 3.6 V connected in series to get 14.4 V.
