However, even the protective functions of electronic circuits can occasionally fail due to abnormalities or semiconductor failures. In the case of lithium-ion batteries, secondary protection is incorporated due to the potential severe consequences of abnormalities, such as fire or explosion.
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.
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.
In the early 1990s, Sony Chemicals Corporation (now Dexerials Corporation) was commissioned to develop a secondary protection component for lithium-ion batteries in case the primary protection failed.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.

Beneficial Properties of Li-Ion BatteriesSafety of Li-Ion BatteriesSecondary Protection For Li-Ion BatteriesSelf Control ProtectorThe Potential and Future of SCPThe “Self Control Protector” (SCP), developed by Dexerials, is a fuse component that physically disconnects the charge/discharge circuit in the secondary protection of Li-ion batteries. The SCP ensures safety by severing the circuit when the battery becomes unstable or when the primary protection is not functioning correctly. The SCP’s role is to i...See more on techtimes xerials.jptermogea
