The auxiliary battery is a 12 V capacity battery.
Usually, it is installed inside the vehicle such as in
the trunk.
• HVs have two batteries. One is the HV battery for the high voltage
system, and the other is the auxiliary battery with a 12 V capacity.
• Not all power supply systems have high voltage in HVs. Similar to
conventional vehicles, controls and accessories (engine, brake,
door locks, audio/navigation systems and so on) use the 12 V
power supply.
• The auxiliary battery supplies electricity for ECUs, which control
the hybrid system. Therefore if the auxiliary battery voltage is
insufficient, the system is not able to be “READY ON
