ELECTRIC MOTOR VEHICLE AND REDOX FLOW MODULE AND CARTRIDGE THEREFOR

An electric motor vehicle with a drive motor, a first rechargeable battery with a first design and a second rechargeable battery with a second design. Electrical energy may be transferred bidirectionally between the drive motor and the first rechargeable battery, and at least unidirectionally from the second rechargeable battery to the drive motor or the first rechargeable battery. The second rechargeable battery in this case includes at least one redox flow cell. Furthermore, a redox flow module is provided with at least one redox flow cell, which includes an electrical coupling for connection to a circuit of a vehicle and a fluid coupling for connection to an electrolyte circuit of said vehicle.
