SERIAL HYBRID DRIVE, VEHICLE AND METHOD FOR OPERATING A SERIAL HYBRID DRIVE

摘要

A serial hybrid drive (100) comprises: an internal combustion engine (1), at least one electric generator (3a, 3b) driven by the internal combustion engine, at least one electric motor (6a, 6b, 6c) which can be operated by a motor and a generator, wherein the at least one electrical generator for generating an intermediate circuit voltage (UZ) of a DC link (5) is formed, which is buffered by means of a DC link capacitor (8), and wherein the at least one electric motor is fed from the DC link voltage, and an independent from the DC link capacitor energy storage (7} is designed to store energy from the DC link when more power is available in the DC link than is needed and to supply power to the DC link when less power is available in the DC link than is needed and / or when a DC link is available Energy request is present.
