The DC rated Circuit Breaker still provides overcurrent protection, if correctly coordinated, even though its intervention time can be not enough to avoid extensive damages on the equipment and on the battery.
Considerations in choosing battery protection ICs Two important parameters in battery ICs are overvoltage threshold and undervoltage threshold. These numbers are the voltage levels at their limit; the IC will cut the cell out of circuit if the cell is being overcharged or over-discharged.
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.
