Abstract
A vehicle has a current collector for feeding traction energy from a two-pole overhead contact line system, an electric or hybrid electric traction drive, and an electric energy storage device for temporarily storing fed traction energy. A first line branch can connect the traction drive to the current collector. A second line branch, which can connect the traction drive and the energy storage device to the current collector, includes a switched-in, galvanically isolating DC-to-DC converter. Due to a third line branch which can connect the traction drive and the energy storage device to the current collector, and which includes a switched-in, non-galvanically isolating DC-to-DC converter, enables higher charging rates for charging the energy storage device to be transmitted while maintaining the protection system.
