Method for operating rechargeable energy storage i.e. accumulator, of e.g. hybrid vehicle, involves providing control device for selecting operating modes from different operation modes of rechargeable energy storage

摘要

The method involves charging a rechargeable energy storage (2) i.e. accumulator, from an external main supply (5) in a charging operation mode, and providing current into the external main supply in a discharging operation mode. A control device (13) is provided for selecting the operating modes from different operation modes of the energy storage. A user requirement is detected directly and provided with certain operational sequence. The operating mode is selected additionally depending on a variable of state of the storage and the main supply. An independent claim is also included for a drive system for a motor vehicle.
