HYBRID BATTERY CONTROL: HYBRID BATTERY SYSTEM: P0A80-123: Replace Hybrid Battery Pack
P0A80-123 - Replace Hybrid Battery Pack

DESCRIPTION

The hybrid vehicle control ECU controls the SOC (state of charge) of the HV battery at a constant level while driving. The HV battery is composed of 20 modules, and each module consists of 12 1.2 V cells in series. The battery smart unit monitors the battery block voltage at 20 locations.









HINT
This DTC cannot be set unless the vehicle is driven for approximately 10 minutes after clearing the DTCs. Two trip detection logic is used. After the first road test, turn the power switch off and perform a road test again.

MONITOR DESCRIPTION

The battery smart unit, which monitors the voltage of the battery blocks, determines that a malfunction has occurred if a voltage difference between the battery blocks exceeds the standard. When the malfunction detection condition is satisfied, the hybrid vehicle control ECU illuminates the MIL and sets a DTC.
