  • Publication number: 20230278511
    Abstract: A vehicle includes an electric power source, a load configured to be supplied electric power from the electric power source, a relay provided between the electric power source and the load, and a processor. The processor is configured to control the relay to a conductive state based on a predetermined drive instruction. The processor is configured to acquire a value of current flowing through the relay and a value of voltage applied to the relay after a predetermined amount of time elapses following conduction of the relay based on the drive instruction. The processor is configured to transmit the value of the current and the value of the voltage that are acquired to an external of the vehicle.

  • Publication number: 20150002973
    Abstract: An overheat protection circuit for protecting a switching element from abnormal overheat is provided, the switching element configured to supply electric power from a power source to a side of a load, including an interruption function part configured to detect a layer short inside the switching element and configured to detect temperature of the switching element. The interruption function part is configured to interrupt the electric power supplied from the power source to the side of the load at an input part of the switching element, when detecting the layer short and detecting that the temperature exceeds a predetermined value, and configured not to interrupt the electric power supplied from the power source to the side of the load at an input part of the switching element, when detecting the layer short and detecting that the temperature does not exceed a predetermined value.
