Abstract
An objective of the present invention is to realize a voltage detection function in a cell type power supply device having a wireless communication function. A cell type power supply deviceis attached to a cell boxof an external load devicealone or in series with another external cell. A housinghas a shape and dimensions based on a cell standard, and front and rear terminals of the external cell held in a cell holderin the housingare to be in contact with an inner positive terminaland an inner negative terminal. An outer positive terminalconnected to the inner positive terminal is provided on a front end surface of the housing, and an outer negative terminalconnected to the inner negative terminal is provided on a rear end surface of the housing. An output transistoris interposed at least one of between the inner negative terminal and the outer negative terminal and between the inner positive terminal and the outer positive terminal. An RFICgenerates a control signal of the output transistor in accordance with a signal received via an antenna. Voltage detection unitsanddetect at least one of a voltage between the inner positive terminal and GND, and a voltage between the outer negative terminal and GND.
