A virtual transmission line includes a charge location and a discharge location. One or more mobile batteries are charged at the charge location. The mobile batteries are transported to the discharge location. At the discharge location, the mobile batteries are connected to electric equipment. The mobile batteries are then transported back to the charge location and the cycle repeated.

The invention refers to a method of preventing automatic leveling during battery replacement, and a computer-program thereof. The method of preventing automatic leveling during battery replacement, according to invention, operates for an electric vehicle equipped with a first electronic control unit (100) in charge with battery replacement and a second electronic control unit (200) of suspension system, the respective ECUs (100, 200) communicating by means of an internal bus system. The method includes the following steps: (51) Sending an information from the first ECU to the second ECU that the vehicle is prepared to perform a battery replacement; (52) Once said information is received by the second ECU, triggering a leveling forbid flag to the suspension system and deactivating it; (53) Once said deactivation has been performed, setting a feedback signal to inform that battery replacement can commence; (54) during battery replacement, setting said feedback signal to inform that battery replacement is ongoing; (55) Upon completion of battery replacement, informing the second ECU that the battery replacement has been finished successfully, and allowing the activation of suspension.
