Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
Can a protection device trip a battery?
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.
