    摘要： A battery supplies electric power to electric equipments of the vehicle. An alternator generates the electric power and charges the battery when an engine of the vehicle is operated. An economical running control section is operable to perform an economical running in which the engine is automatically stopped when the vehicle is in a predetermined engine stopping condition and the engine is automatically restarted when the vehicle is in a predetermined engine restarting condition. A calculate section is operable to calculate an available current value which is available to supply to the electric equipments from the battery. A feed limiting section is operable to limit to supply the electric power to the electric equipments from the battery. The economical running control section controls the economical running based on a total value of necessary current values which are necessary for the respective electric equipments and the available current value. The feed limiting section limits to supply the electric power to the electric equipments from the battery based on the total value of the necessary current values and the sum of the available current value and a generated current value of the alternator.

    摘要： A battery monitor apparatus and method for an automotive battery system including a battery (6) for supplying power to in-vehicle electrical equipment and sensors (1) for detecting battery voltage, the charge/discharge current and the battery temperature are disclosed. The capacitance and the internal actual resistance of the battery (6) are calculated at the time of starting the engine. Further, the theoretical internal resistance of the battery corresponding to the ambient temperature and the battery open-circuit voltage during the stationary engine state are detected in advance. Based on the change in the battery open-circuit voltage, the battery change is provisionally determined. After that, battery change or degeneration can be determined based on battery capacitance, the actual and theoretical internal resistance values of the battery, the battery open-circuit voltage and the provisional battery change determination value.

    摘要： A first battery supplies power to an electrical load of a vehicle when an engine is in a normal operation, A second buttery supplies power to the electrical load of the vehicle when the engine is in an economical operation. A voltage regulator regulates voltages of the first battery and the second battery. A current limiter limits a current value flowing from the voltage regulator to the second battery to a limiting value. An engine stopping unit stops the engine when a first predetermined condition is established. An activator starts the engine when a second predetermined condition is established. A current detecting unit detects the current value when a second battery is charged. A changing unit changes a limiting value between a first limiting value and a second limiting value which is higher than the first limiting value according to the detected current value in a case where the voltage of the second battery is no more than a second predetermined value and the voltage of the first battery is no less than a first predetermined value.
