Abstract
PURPOSE:To eliminate the loss of electron for showing and facilitate confirmation, by charging a secondary battery via a power switching element, and by sensing the rise of a temperature during the charging, with a temperature sensor, to show a charging-progressive state. CONSTITUTION:A secondary battery 2 for feeding current to, a motor fan 3 is charged via a power switching element 5, and the element 5 is permitted to come in contact with the internal back side surface of a main unit 1, and is set. Besides, on the external surface of the main unit in close contact with the element 5, a temperature sensor 7 for sensing the temperature rise of the element 5 is set, and an opening section 8 for showing 'charging', 'charging completion', and the like is set. When charging current is permitted to flow in this state, then heat is generated from the element 5, and so the heat generation is sensed by the temperature sensor 7, and the 'charging' is shown. Besides, when the battery is charged up to specified voltage and an over-charging-proof circuit 13 is worked, then the charging current is turned OFF and the element 5 is cooled, and so it is sensed and the 'charging completion' is shown.
