Abstract:
1. An electrical drive system of a vehicle, comprising: an electrical energy store; and an electrochemical energy store, connected in parallel to the electrical energy store; device with a forward direction away from the electrochemical energy store is arranged in a connecting line between the electrical energy store and the electrochemical energy store, in order to prevent the electrochemical energy store from being charged from the electrical energy store and an inductor is arranged in the line circuit of the electrical energy store and the electrochemical energy store, in order to form at least one of a step-up and a step-down converter, wherein the vehicle is a rail vehicle, the electrical energy store and the electrochemical energy store are connected to a voltage intermediate circuit of a converter, the electrochemical energy store is connected to a charging device for supplying electrical energy via an overhead line or a live rail, and at least two components, which can be switched off, are connected to form the converter, one of the at least components being connected to the energy electrical energy store and the electrochemical energy store while another of the at least two components is connected to the charging device.
