(JP9200965-A)      The indicator (1) has a detector (3) which determines the discharged and fully charged points for a battery (2) by measuring the battery potential and the battery temperature respectively. The electrical energy stored or used is measured by an integrator (4).    The integrator uses the discharged and fully charged points, and their quantities of stored energy, as reference levels for the integration of the battery current. A display unit (5) shows the remaining energy in the battery and the equivalent mileage available. The integration is always stopped at the fully charged point to prevent the overestimation of the quantity of the remaining battery energy.    USE/ADVANTAGE -   For electric vehicles. Remaining battery energy is shown accurately even if some discharge cycles have only been partial.
