A method and a vehicle electrical system having an inverter, an electrical energy store, an electrical machine and an AC transmission terminal. The inverter has first and second sides and is configured to transmit power between these sides. Two output terminals of the inverter are connected or connectable to the energy store on the first side of the inverter. At least two phase current terminals of the inverter are connected or connectable to the electrical machine on the second side of the inverter. At least one of the charging inputs of the vehicle electrical system is connectable to a respective inner motor phase of the electrical machine by a switching device controlled by a controller. The vehicle electrical system initially charges the electrical energy store with a first voltage, and then charges the electrical energy store with a second voltage, which second voltage is higher than the first voltage.

On-board vehicle electrical system for charging an electrically operated vehicle, and method

A vehicle electrical system having an electrical energy store, a direct voltage converter and a direct current transmission connection is described. The direct current transmission connection is connected to the energy store via the direct voltage converter. The vehicle electrical system also has a bypass switch which connects the electrical energy store in a switchable fashion to the direct voltage transmission connection. In addition, a method, a charging system, a charging station and a further vehicle electrical system are described.
