6 FAQs about [Protective device for multi-body batteries]

What is a battery protection unit (BPU)?

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.

How can multifunctional materials improve battery safety?

Utilizing multifunctional materials within the cells is a promising approach to enhance battery safety so that savings on the requited battery protection can be made. The approaches have been designed to either prevent the short circuit or to isolate the area of contact so that all of the energy in the battery is not available for release.

What is a battery protection circuit / IC?

Battery protection circuits / IC solutions and reference designs that allow easy design-in and ensure safe charging and discharging - prevent damage and failures.

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.

How a battery protection device should be sized?

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.

What should be considered when choosing a battery protection system?

Need to consider the case also of parallel battery strings and the case when one battery string is damaged or not available. The nominal current of the remaining battery strings in the parallel system will increase and the protection system must not trip due to this.
