Charging Control System by Temperature Sensing of Charger for Electric Vehicle (A CHARGER CONTROL SYSTEM BY MEANS OF TEMPERATURE SENSORS IN A CHARGER FOR AN ELECTROMOBILE)

摘要

The present invention relates to a charging control system for detecting the temperature of a battery charger for an electric vehicle, which measures the temperature of the battery and the temperature of outside air through temperature sensors (5, 6) 2c in the microcomputer 2, the temperature difference between the battery temperature and the outside temperature is calculated and the ratio is changed to change the duty factor with respect to the threshold value and the charge current is controlled. It is possible to prevent overheating and overcharging of the battery to prevent damage to the battery, thereby improving the lifetime and durability of the battery and increasing the efficiency of charging. As a result, it is possible to reduce the maintenance and repairing cost by replacing the battery, This will contribute to the improvement of the performance of the automobile.
