| Abstract | A protection system for an electromagnetic relay mounted on a vehicle is configured to protect the electromagnetic relay from causing a coupling failure due to freezing of the electromagnetic relay. The system includes a temperature detector, a cooler, and a control unit. The temperature detector sequentially measures an ambient temperature of a location in which the electromagnetic relay is disposed and outputs information on a change in the ambient temperature. The cooler cools an electric power line coupled to a fixing terminal of the electromagnetic relay. The control unit activates the cooler to cool the electric power line in a case where the control unit determines that the electromagnetic relay has a possibility of freezing on the basis of the information on the change in the ambient temperature from the temperature detector. |
