1. A converter system for electrically driving a vehicle, comprising a grid-side converter, a DC link with a first potential conductor at a first electrical potential and a second potential conductor at a second electrical potential different from the first electrical potential, and a motor-side converter, wherein the motor-side converter allows a bidirectional flow of energy, wherein the grid-side converter has a single phase on the input side and is able to be connected to a supply grid, being connected, on the output side, to the DC link 944 and obtaining energy from the supply grid during operation, wherein the DC link connects the grid-side converter to the motor-side converter, wherein the DC link comprises a first electrical energy storage between the first potential conductor and the second potential conductor, wherein a further electrical energy storage is connected to the DC link via an electrical connection, and wherein the flow of energy from the DC link into the further electrical energy storage is controllable, characterized in that the grid-side converter is a unidirectional converter and allows a flow of energy from the supply grid into the DC link, and a flow of energy from the further electrical energy storage into the DC link is controllable. |
