Slow charging method and on-board charger for environmentally-friendly vehicle using the same
First Claim
1. A slow charging method of a vehicle including an on-board charger, comprising:
- detecting, by a controller, a charging request;
detecting, by the controller, temperature of the on-board charger in response to detecting the charging request;
determining, by the controller, whether the temperature of the on-board charger is within a predetermined temperature range;
adjusting, by the controller, a charging output of the on-board charger to a predetermined value when the temperature of the on-board charger is within the predetermined temperature range; and
charging, by the controller, a battery of the vehicle with the adjusted charging output of the on-board charger,wherein the adjusted charging output of the on-board charger is less than a previous charging output of the on-board charger, anda charging time of the adjusted charging output is greater than that of the previous charging output.

Abstract
A slow charging method of a vehicle and an on-board charger using the same are provided that improve charging efficiency and thus save a charging cost by adjusted charging output of the on-board charger based on temperature thereof. The method includes detecting, by a controller, a charging request and detecting temperature of the on-board charger in response to detecting the charging request. The controller is configured to determine whether the temperature of the on-board charger is within a predetermined temperature range and adjust charging an output of the on-board charger to a predetermined value when the temperature of the on-board charger is within the predetermined temperature range. The controller is then configured to charge a battery of the vehicle with the adjusted charging output of the on-board charger.
