Abstract

PURPOSE:To eliminate the accumulation of display errors for proper display at all times. CONSTITUTION:Based on remaining capacity data in a memory circuit 13e, a display drive circuit 18 generates display data, and based on the detected signal from a discharge completion voltage detection circuit 13c, the remaining capacity data in the memory circuit 13e is cleared, and with this clearing process, the display on the display device 19 is cleared, and in addition, this processing circuit 13 is, at least, constituted as a microcomputer circuit.
