OVERHEATING PREVENTING METHOD FOR HIGH-VOLTAGE CABLE IN VEHICLE

摘要

PURPOSE: A method for preventing a high voltage cable for a vehicle from an overheating is provided to prevent a high voltage cable from overheating even though the existing high voltage cable is used without enhancing specifications. CONSTITUTION: A method for preventing a high voltage cable for a vehicle from an overheating comprises next steps. An estimated temperature is obtained by inputting a present surrounding temperature and current to a temperature estimation model estimating a temperature of a high voltage cable according to the current flowing through the high voltage cable and the temperature measured by a temperature sensor(S101). An limitation value of the current to control the current flowing to the high voltage cable according to the estimated temperature in a temperature estimation step(S102). The limitation value of the current set in a first limitation value setting step and the existing limitation value of the current are compared so that the minimum value is set as a final limitation value of the current(S103).
