This is performed by the D conversion circuit 16, and when -ΔV is detected in the graph of elapsed time versus voltage value shown in FIG. 3, it is determined that charging is complete, and energization to the charging terminal is terminated. During this charging period, the temperature detection circuit 15 shown in FIG. 2 detects an abnormal temperature, and if the microprocessor 14 determines that the temperature is abnormal, the second
The LED 17 shown in the figure is in a slow blinking state and a half-brightness state when lit. If the charging terminal voltage value is an abnormal voltage value, the lamp blinks quickly and turns on at half brightness. The voltage comparison circuit 13 shown in FIG. 2 is for detecting whether or not a secondary battery is connected to the charging terminal. Further, the LED brightness control circuit 18 shown in FIG. 2 is for controlling the current of the IED 17 under the control of the microprocessor 14.
