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 selected protection device must trip in case of a fault in less than 100 ms. In case the fault current provided by the battery does not allow for the finding of protection devices, such as a Circuit Breaker or fuse, that meets the derating criteria stated in point B, it is hence possible to increase the multiplier up to 0.7.
A protection device must be sized properly so that the energy flowing from the batteries during the failure will not cause damage to the batteries or other components along the short circuit path. The protection must clear the fault in less than 100 milliseconds. The impedance of the line is mainly resistance and inductance.
These can be equipped with a monitoring device connected to the UPS or BMS to warn if a fuse has tripped or is disconnecting the battery from the UPS. The DC rated Battery Circuit Breaker (BCB) provides still overcurrent protection, if correctly coordinated, even though it is not as fast as the fuses.
