Filed: 1990-02-20
Abstract: PURPOSE:To display an index indicating residual power of a storage battery with high precision by calculating an index indicating consumption rate per unit hour from a previous discharge until present discharge and displaying the index indicating residual amount obtained based on the above index. CONSTITUTION:When time dt has elapsed since an operation switch SW was turned ON and a storage battery 4 was connected to a load 6 (discharge), an index (%) Q20 indicating a standard consumption amount per unit hour dt is subtracted from an index (%) Q0 indicating residual amount of the storage battery 4, and further a unit hour dt is added to actual discharge time tD from the time when the storage battery was fully charged. The discharge time tD is written into a non-volatile memory 9 each time. The index Q0 at this time is displayed on a display unit 7. When discharge is to be continued, the above operation is repeated until the operation switch SW is turned OFF. When the storage battery 4 is empty after continuance of discharge, the discharge time tD which was calculated most recently is finally written into the non-volatile memory 9 as total discharge time.
