Even probably the most superior electrical automobiles include one main disadvantage — batteries nonetheless suck. You may be capable of get a number of hundred miles on a cost with one of many costly high-capacity batteries, however recharging will take ages.
even the most advanced electric vehicles come with one major drawback — batteries still suck. You might be able to get a few hundred miles on a charge with one of the expensive high-capacity batteries, but recharging will take ages.
Sweden's latest foray into roads that can provide electric power to vehicles is perhaps one of the least futuristic options possible, but that doesn't necessarily make it any less effective. A two-kilometer pilot stretch of the E16 motorway has been equipped with overhead caternary wires, and trucks modified with pantographs are running tests to see how well the it works.
The
Swedish government is partnering with the private sector to deploy
overhead wiring that could allow electric lorries to travel on roads
indefinitely, without having to worry about lengthy recharging or
massive battery packs. A 2km pilot stretch of the E16 motorway has been
equipped with overhead catenary wires, and trucks modified with
pantographs are running tests to see how well it works.
Power delivery systems like these have been around since the 1880s, and
are still used today. In crowded city centres, overhead wires are the
safest way to provide power to buses and trolleys following fixed
routes, and they're also the only way to keep high speed intercity
trains fed. Vehicles that run on rails harvest electricity from a single
overhead wire, using their tracks to complete the circuit, buses and
other vehicles with tires need a pair of overhead wires instead.
The
trucks used in the test are hybrid electrics, meaning they have biofuel
engines and small 5 kilowatt-hour lithium-ion batteries. The battery provides
enough juice to travel just a few miles, but that’s only supposed to be
used to get from one electrified road to another. When the truck is
driving under the wires, all its power comes from the embedded power
supply. The biofuel engine acts as a backup
