Claims

[Claims for Utility Model Registration] (1) In a vehicle power supply in which a generator driven by an engine and a battery are electrically connected in parallel, a current detector is provided to detect the current of the battery, and a current detector for detecting the current of the battery is provided. Based on the signal from the detector, there is a discharge comparison calculation unit that stores the cumulative discharge amount of the battery, compares it with the set discharge amount, and outputs it; and a discharge comparison calculation section that stores the cumulative amount of battery charge and compares the cumulative amount of charge with the cumulative discharge amount. When using an external load, the method is characterized in that it is provided with a central control section having a charge comparison calculation section that outputs the charge, and an ignition switch and a starter switch that are opened and closed by signals output from the central control section. Engine control device. (2) The engine control device when using an external load according to claim (1), characterized in that an electric double layer capacitor is connected in series with a vehicle power source and its current value is input to the central control unit. Engine control device when using external load.
