A heater apparatus includes a base member, a cover member supported by the base member, a cloth member provided between the base member and the cover member to hold a heater wire, and a heater temperature sensor brought into contact with the cloth member, covered on a base member side facing the base member and a cover member side facing the cover member with the cloth member, and configured to detect a temperature of the heater wire. The cover member has a cover recessed portion recessed towards the base member in an overlapping region where the cloth member on the base member side and the cloth member on the cover member side of the heater temperature sensor overlap.

Heater apparatus

A main relay protection device includes a motor generator, a rechargeable driving battery, an externally-coupled charger, a main relay, a charging bus bar, a charging relay, a main relay temperature sensor, and a controller. The motor generator drives a vehicle. The battery supplies power to the motor generator. The charger charges the battery. The main bus bar is disposed between the battery and the motor generator. The main relay is disposed in the main bus bar. The charging bus bar is disposed between the main bus bar and the charger. The charging relay is disposed in the charging bus bar. The sensor is configured to detect a temperature of the main relay. The controller performs ON-control on the charging relay in a state where the main relay is turned on, if the detected temperature of the main relay is higher than or equal to a preset heat radiation starting threshold.

Main relay protection device

An external heater operation determination system includes, in a vehicle: a first device to be heated by an attached external heater; a second device, separate from the first device, to be cooled by a refrigerant; a circulation device configured to circulate the refrigerant through a circuit; and a temperature detection device that is configured to detect a temperature of the refrigerant and disposed such that if the refrigerant is not circulating through the circuit, the temperature of the refrigerant detected by the temperature detection device in the circuit does not rise even if the external heater is operating, whereas if the refrigerant is circulating through the circuit, the detected temperature of the refrigerant changes. The external heater operation determination system includes a determination device able to determine that the external heater is not operating on a basis of a change in the temperature after the circulation of the refrigerant.
