Abstract
A relay temperature measuring device is provided. The device includes a sensor that measures an output of a battery and generates output measurement information and one or more relays that are disposed on a conductive line between the battery and a load. Additionally, a controller compares a relay temperature calculated using both-end measurement power information generated by measuring both ends of a conductor in a vehicle and the output measurement information with a preset temperature reference value, and connects or disconnects the relays based on a comparison result.
Claims8
A relay temperature measuring method, comprising:
- measuring, by a sensor, an output of a battery to generate output measurement information;
- measuring, by a controller, both ends of a conductor in a vehicle to generate both-end measurement power information;
- comparing, by the controller, a relay temperature, calculated using the output measurement information, with a preset temperature reference value;
- and
- connecting or disconnecting, by the controller, one or more relays disposed on a conductive line between the battery and a load, based on a comparison result;
- wherein the relay temperature is calculated without a temperature sensor.
