(DE4418194-A1)      The method entails calculating an internal resistance value (r) of the battery based on terminal voltage (VH) in a disconnected state to electrical loads (4), a terminal voltage (VL) in a selectively connected state to the electrical load and discharge current value (I) in this connected state.    The remaining battery capacity at the present temp. condition is obtained from a map showing a relationship between a remaining battery capacity, discharge current (I) and internal resistance (r). Finally, the obtained remaining battery capacity is transformed into a remaining battery capacity at a standard temp. condition using a correction coefft read from a second map in accordance with sensed battery electrolyte temp.    USE/ADVANTAGE -   For rechargeable storage batteries estimating and displaying remaining capacity of battery, regardless of state of degradation of plates or electrolyte temp. in a wide variety of applications, such as electrical power sources for automobiles, for auxiliary equipment, lighting equipment, or propulsion power source for electric vehicles.    (US5404106-A)      The remaining capacity estimating system calculates an internal resistance value of the battery based on a terminal voltage in a disconnected state to electrical loads, a terminal voltage in a selectively connected state to an electrical load and a discharge current value in this connected state.    The remaining battery capacity at the present temperature condition is determined from a map showing a relationship among a remaining battery capacity, a discharge current and an internal resistance. The obtained remaining battery capacity is transformed into a remaining battery capacity at a standard temperature condition.
