PROBLEM TO BE SOLVED: To prevent the drop of the voltage of a battery dering charging, and obviate the necessity to perform supplementary charging, by storing the start time of the work of the car body after completion of past charging, and automatically operating the start time of the work of the car body, and performing the supplementary charging before a certain time. SOLUTION: In the first place, the time of supplementary charging is operated. Next, it is judged whether a charging plug is extracted or not. Next, if the charging plug is extracted, it is judged whether the normal charging is finished or not. Then, if the normal charging is finished, the time of supplementary charging is operated and stored. Here, for the operation and storage of the supplementary charging start time, first the forecast start time of the work of the car body is operated (STEP 3A-STEP 3F), and a certain time required for the preset supplementary charging is subtracted (STEP 3G), and the supplementary charging start time is stored (STEP 3H), Hereby, even if the charging stops automatically at the time of full charging, the supplementary charging is performed automatically a certain time before the work start forecast time, and the use is possible as full charging at the time of charging start. |
