Document Type and Number:
Japanese Patent JP2018061387
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To determine an appropriate warning voltage while considering an influence due to a difference in discharge characteristics of a power source to be used.SOLUTION: Electronic equipment comprises: voltage detection means for detecting a voltage of a power source; and control means for calculating a voltage drop of the power source from currents running from the power source to a load and an impedance of a current path running from the power source to the load. When the voltage of the power source detected by the voltage detection means is a predetermined voltage, the voltage drop of the power source is calculated, and the calculated voltage drop is compared with a reference voltage drop, and a difference therebetween is calculated, and when the calculated voltage drop is smaller than the reference voltage drop, it is determined that setting a warning voltage low only by a value equivalent to the difference is appropriate, and information corresponding to the determination result is displayed by display means.SELECTED DRAWING: Figure 1
