VERFAHREN UND VORRICHTUNG ZUM BETREIBEN EINES HYBRIDENERGIESPEICHERS IN EINEM FAHRZEUG MIT EINEM HYBRIDANTRIEBSYSTEM

摘要

The method involves determining an operating parameter of a hybrid drive system (2), a charging condition of a battery and a voltage of a capacitor storage. The voltage of the capacitor storage is lowered to a charging terminal voltage level of the battery and a switch connecting a hybrid energy storage and the capacitor storage is closed, when an internal combustion engine speed is greater than a threshold, to charge the battery. An independent claim is also included for a device for operating a hybrid energy storage.
