The cost really varies depending on the vehicle model and the desired battery storage capacity. The price range will go from 8 000 € for a small city car (with 75 km of autonomy) to more than 50 000 € if it's an exceptional car, and / or if you want/can put 600 km of autonomy. For trucks, it really depends on the complexity of the retrofit and... the customer's need. Quite classically, costs will go down in the future thanks to growing sales, economies of scale and purchasing volumes for batteries and parts. And even more if the State, the region, the city participates in the conversion premium that we believe is necessary.
