Li-Ion Battery Control System: Fail-Safe

When Li-ion Battery Controller (LBC) detects a malfunction of the Li-ion battery, it enters the control mode that protects the battery by stopping or restricting the output/charging from/to the battery.

The fail-safe mode differs depending on the contents of the detected malfunction.
