Abstract:
PROBLEM TO BE SOLVED: To provide an electric power supply device capable of determining a difference between an operating time up to the present and a residual life time that is actually assumed.SOLUTION: An electric power supply 100 comprises: an electric power supply unit 10; a timing circuit 21; a calculation circuit 22; and a display circuit 23. The timing circuit 21 measures an operating time of the electric power supply unit 10. The calculation circuit 22 calculates a total operating time by totaling the operating times measured by the timing circuit 21, and calculates a residual life time on the basis of information from the electric power supply unit 10. The display circuit 23 can display the total operating time and the residual life time as information related to a life of the electric power supply unit.SELECTED DRAWING: Figure 1
