System control unit and method for controlling a charging system that is provided for charging an electrical energy storage device, as well as charging system and vehicle

A vehicle, comprising:

• a charging system which includes an electric generator and an internal combustion engine that is mechanically connected with the electric generator;
• a system control unit for controlling the charging system that is intended for charging an electrical energy storage device, the system control unit including:
• a generator controller for controlling the electric generator;
• an engine controller for controlling the internal combustion engine;
• and
• a transmitting device for transmission of messages, whereby the engine controller is connected with the generator controller by way of the transmitting device, and whereby the engine controller is operable in that a message containing information about an operating state of the internal combustion engine is produced and said message is sent to the generator controller via the transmitting device, wherein the engine controller is operable in that a deliverable maximum output of the internal combustion engine is variably determinable depending on at least one predefined parameter, and information relating to the operating status of the internal combustion engine is dependent on the maximum output of the internal combustion engine, and wherein a rated output is defined for the internal combustion engine, and the engine controller is operable in that the maximum output of the internal combustion engine is definable depending on at least one predefined parameter in such a way that it is higher than the rated output.

A method for controlling a charging system that is intended for charging an electrical energy storage device which includes an electric generator and an internal combustion engine that is mechanically connected with the electric generator, said method including the steps of:

• controlling the electric generator by way of a generator controller;
• controlling the internal combustion engine by way of an engine controller;
• and
• producing a message by the engine controller which includes information in regard to the operational state of the internal combustion engine, and this message is transmitted to the generator controller via a transmitting device for the transmission of messages which connects the engine controller with the generator controller, wherein the engine controller is operable in that a deliverable maximum output of the internal combustion engine is variably determinable depending on at least one predefined parameter, and information relating to the operating status of the internal combustion engine is dependent on the maximum output of the internal combustion engine, and wherein a rated output is defined for the internal combustion engine, and the engine controller is operable in that the maximum output of the internal combustion engine is definable depending on at least one predefined parameter in such a way that it is higher than the rated output.
