Abstract
A power cable failure prediction apparatus and method includes a temperature sensor configured to measure a temperature around a vehicle, a resistance measurer configured to measure a resistance of a cable connected to a drive motor of the vehicle, and a controller configured to predict in advance whether the cable is damaged by comparing the temperature around the vehicle with the resistance of the cable.
Claims6
A power cable failure prediction apparatus, comprising:
- a temperature sensor configured to measure a temperature around a vehicle;
- a resistance measurer configured to measure a resistance of a cable connected to a drive motor of the vehicle and to measure a resistamce of a braid constituting the cable;
- a controller configured to predict in advance whether the cable is damaged by comparing the temperature around the vehicle with the resistance of the cable, wherein the controller is further configured to,
- measure a rate of change in the temperature via the sensor;
- measure a rate of change in the resitance of the cable via the resitance measurer;
- and
- determine that the cable is damaged, in response to the rate of change in the resistance of the cable being greater than a rate of change in the temperature around the vehicle.

A method of predicting a failure of a power cable, the method comprising:
- measuring a temperature around a vehicle;
- measuring a resistance of the power cable, wherein the power cable is connected to a drive motor of the vehicle;
- measuring a resistance of a braid constituting the power cable;
- predicting in advance whether the power cable is damaged, wherein the predicting comprises:
- measuring a rate of change in the temperature around the vehicle;
- and
- measuring a rate of change in the resistance of the power cable,
- wherein, when the rate of change in the resistance of the cable is greater than the rate of change in the temperature, it is determined that the power cable is damaged.
