Li-Ion Battery Controller (LBC): Fail-Safe

WARNING: This page is about a different car, the 2016 Infiniti Q50. However, it is still accessible from the selected car via links, so may be relevant.

When detecting a malfunction in Li-ion battery, the Li-ion battery controller (LBC) issues a request to HPCM (Hybrid power train control module) for limiting or stopping the output from the Li-ion batter so that the system can be protected.
