  • Patent number: 12078139
    Abstract: A vehicle includes a first power system, a second power system, a switching relay, and a relay controller. The first power system is coupled to an engine restart motor. The second power system is provided independently of the first power system and is coupled to a starter and an accessory. The coupling state of the switching relay is switchable to an on state in which the first power system and the second power system are coupled, and to an off state in which the first power system and the second power system are not coupled. The relay controller is configured to receive a supply of electric power from both the first power system and the second power system and to control the coupling state of the switching relay.
