An apparatus is provided to control a power voltage on a power-supplying line extending from a generator and connecting to a battery and eclectic loads. The apparatus is mounted on a vehicle and comprises a detecting device, a calculator, and a controller. The detecting device detects pairs of voltage and current of the battery. The calculator calculating a control current on the basis of the detected pairs of voltage and current and a target voltage for the power voltage. The pairs of voltage and current are used to calculate an internal resistance and/or a regression line of the battery. The controller controlling a charge and discharge current of the battery on the basis of the control current so that the power voltage is controlled to the target voltage.
An apparatus for controlling a power voltage (VL) on a power-supplying line (5) extending from a generator (7, 7A) and connecting to a battery (1) and eclectic loads (L), the apparatus being mounted on a vehicle (VE), the apparatus comprising:
An apparatus for calculating an electric quantity indicating a state of a battery (1) being mounted on a vehicle (VE), the battery being connected via a line (5) to a generator (7, 7A) and electric loads (L), the apparatus comprising:
A method of calculating an electric quantity indicating a state of a battery (1) being mounted on a vehicle (VE), the battery being connected via a line (5) to a generator (7, 7A) and electric loads (L), the method comprising steps of:
