Abstract: A resonance power conversion device includes a bridge circuit, a transformer, a current detection circuit, and a control circuit. The bridge circuit includes a plurality of switching elements and receives a DC power. The transformer is connected to an output side of the bridge circuit. The current detection circuit detects a value of a current flowing through at least one of the plurality of switching elements. The control circuit determines whether or not an abnormality is occurring in the resonance power conversion device, based on the value detected by the current detection circuit at a predetermined time during a switching control.

Abstract: A charging device includes an AC/DC converter, a first DC/DC converter, a second DC/DC converter, and an inductance element. The AC/DC converter is connected to an external power source and configured to convert AC power into DC power. The first DC/DC converter is configured to convert a voltage the DC power outputted from the AC/DC converter and supply the resultant DC power to a first battery. The second DC/DC converter is connected in parallel to the first battery on the output side of the first DC/DC converter, and configured to convert a voltage of the DC power outputted from the first DC/DC converter and supply the resultant DC power to a second battery. The inductance element is provided between the first DC/DC converter and the second DC/DC converter, and connected in series to the first DC/DC converter and the second DC/DC converter.

Abstract: Provided is a vehicle-mounted charging device in which a charging circuit subjects power supplied from an external power supply to power conversion and supplies power to a battery and a PTC heater in parallel. The vehicle-mounted charging device is provided with a control device which, when temperature adjustment of the battery by the PTC heater and charging of the battery are carried out at the same time, controls an output current of the charging circuit so as to approach a total value of an allowable value of charging current for the battery and a current consumption of the PTC heater at each time point during charging. The allowable value of charging current for the battery and the current consumption of the PTC heater are specified on the basis of battery characteristic information of the battery and heater characteristic information of the PTC heater which are stored in advance.

Abstract: An on-board control device relays data communication between a vehicle module and a vehicle ECU which generates a signal for commanding a driving mode of a vehicle. The on-board control device includes a first interface via which communication with the vehicle ECU is performed, and a second interface via which communication with the vehicle modules is performed. The first interface relies on specifications for communication with the vehicle ECU, and the second interface does not rely on the specifications for communication with the vehicle ECU.
