The backup boost converter uses a semiconductor relay. The semiconductor relay also functions as a fuse. When overcurrent is detected, the relay is turned off to protect the circuit.
The backup boost converter supplies battery voltage to help make up for the voltage drop that occurs when the engine is restarted. This prevents the operation of the following equipment from being interrupted due to low battery voltage.
Skid Control ECU
Power Steering ECU Assembly
Steering Sensor (Spiral Cable with Sensor Sub-assembly)
Combination Meter Assembly
Remote Touch
Smart Door Control Receiver Assembly
Parking Brake ECU Assembly
Air Conditioning Control Assembly

An external backup boost converter (eco run vehicle converter assembly) is used.
When the audio system is used during idle stop, the external backup boost converter (eco run vehicle converter assembly) compensates for the voltage drop to supplement audio playback by stabilizing the sound quality.
