To be able to maneuver without overhead wires, the locomotives are equipped with a Lithiu-Ion battery. The maximum speed when using the battery is 40 km / h (with overhead line 80 km / h). The power is 200 kW via the battery (catenary 500 kW). The battery is charged via the overhead line and by recovering braking energy.
