A battery management system requires protection from threats such as overcurrents, surges and ESD. Points for circuit protection include fuses (1), TVS diodes (3, 5), TVS diode arrays (4, 6) and high-voltage fuses (7). Protecting the BMS BMS circuit protection is critical for both in safety and reliability.
Batteries store a large amount of energy, and sudden discharge or fault can lead to catastrophic failures. To prevent unsafe operations and dangers like overcharging, overheating, and short circuits, a battery protection system is crucial to handle and maintain the battery's functional factors and protective mechanisms.
The battery management system’s voltage range and interrupt rating requirements depend on the battery configuration. Within the system, each module of batteries has cell monitoring systems. These subsystems monitor the voltage for proper balance.
Another internal protection is PTC. PTC is a thermal fuse which used to prevent the thermal runaways. PTC will shutdown the batteries if the battery temperature is overheated , . circuit and keep the cell in open state. Table 3 shows the comparison between LIB fault, types of abuse and how the fault will be managed.
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.
The battery protector functions in tandem with the battery monitor and responds whenever it notices an anomaly. For instance, the protector will take the appropriate actions, such as disconnecting the battery or altering the charge/discharge rates, to prevent harm if the battery voltage exceeds the safe limits.
