System Description
- DESCRIPTION
- The electric power control system is provided to supply power constantly to the vehicle equipped with many electronic systems.
The electric power control ECU always monitors the battery condition. In accordance with the battery condition, the electric power control ECU implements various control measures on systems that operate while the vehicle is parked or systems that require a large amount of power in a short period of time.
- The electric power control system is provided to supply power constantly to the vehicle equipped with many electronic systems.
- RECHARGE CONTROL
- While the engine is running, the electric power control ECU monitors the battery recharging state.
The ECU then adjusts the generated voltage so that the actual current value is close to the target current value.
The ECU sends recharging control signals to the ECM via CAN communication.
- While the engine is running, the electric power control ECU monitors the battery recharging state.
- LOAD CONTROL
- While the engine is running, the electric power control ECU temporarily limits the power consumption of large systems to optimize the battery recharging state.
The ECU sends load control signals to load control related systems via CAN communication.
- While the engine is running, the electric power control ECU temporarily limits the power consumption of large systems to optimize the battery recharging state.
- POWER SAVE CONTROL WHILE PARKED
- Depending on the amount of time the vehicle is parked, the electric power control ECU cuts power to systems that it determines to be unnecessary.
The electric power control ECU uses the power cut relay to control power supplied to power cut linked parts.
- Depending on the amount of time the vehicle is parked, the electric power control ECU cuts power to systems that it determines to be unnecessary.
