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.

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.
