Device for supplying power to electrical system of e.g. motor vehicle, has energy reservoir designed to supply energy to electrical system and/or for pre-defined driving profile in temporary manner

摘要

The device has a generator (G) driven by an internal combustion engine (M) for supplying power to an electrical system (BN) and/or charging an energy reservoir (Res1). Another energy reservoir (Res2) is coupled with a charge interface (IF) and charged by a separate electrical system-independent electricity mains supply (SN). The latter energy reservoir is designed to supply energy to the electrical system and/or for a pre-defined driving profile in temporary manner. The two energy reservoirs are made from a common energy storage (Bat). The two energy reservoirs are designed as a lead battery, a nickel metal hydride battery, a lithium polymer battery, a lead gel battery or a lithium ion battery. An independent claim is also included for a method for operating a vehicle such as motor vehicle or commercial vehicle.
