    Abstract: PURPOSE: To enable a visible indication in a specific charge state by forming a device such that the computer has a processor, the processor monitors battery conditions, and electric signals are generated for indicating them. CONSTITUTION: The electric power administration processor PMP 30 operates to measure an ambient temperature AT, a voltage V of the battery, electric current I and BT respectively by the use of a thermistor 46, a resistor 40 and calculation amplifiers 38-1 to 38-4 connected to the thermistor 42. The PMP 30 selects one from a plurality of discharge tables stored in ROM 24, confirms the charge zone of a battery 11 by using signals I, V, and controls the icon display 52. The fuel icon has three panels, and when the battery 11 is charged completely, all panels become lighted. When electric power is consumed, panels are made off consecutively to indicate conditions of 2/3 charge and 1/3 charge. When consumption further advances, the remained panels flash on and off, and thereafter all panels become off, so that the consumption of the battery 11 is indicated.
