3 gets nearly double the range of the Nissan
Leaf by using nearly double the amount of battery
but engineers are using a multitude of work rounds to do better: aerodynamics, lightweighting even including structural electronics where dumb
structure is replaced by supercapacitors
or solid state batteries
. Add more efficient motors and powertrain. Fuel cell hybrids retain the cachet of most expensive solution with a long on-road charging time if you factor in the time to find that rarity, the hydrogen charger. Very long distance with large hydrogen tanks is impracticable.
However, at IDTechEx
we believe that there is an excellent solution being proved for the long distance battery vehicle, starting with trucks. The battery does not expand to an unwieldy 400kWh. A new dynamic charging approach was presented at EVS29 Canada by Patrik Akerman of Siemens
. Dynamic charging is a term most often applied to coils in the road that charge the vehicle as it goes along but, as he pointed out, this has severe difficulties with roads wearing out early, safety and damage from vehicles and roadworks. Height variations, snow, dirt, cost and other problems have been cited by others. Following a study, Siemens has decided not to work on this. Akerman favours the elegant, affordable solution of intermittent overhead catenary at a mere Euros 2.2 million per kilometre for charging trucks on the move which means that they can still overtake (the old trolley buses could not).
