Li-Ion Battery Control System: Fail-Safe

When Li-ion Battery Controller (LB C) 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.

FAIL-SAFE PATTERN

Pattern A: No driving, Charge stop, and EV system warning lamp illuminate
Pattern B: Driving output power limit, Charge stop, and EV system warning lamp illuminate (When LB C is re-activated, No driving and Charge stop)
Pattern C: Driving output power limit, Charge limit, and EV system warning lamp illuminate
Pattern D: EV system warning lamp illuminate
Pattern E: Driving output power limit and EV system warning lamp illuminate
