Charge the electric car at the highway at 130 km/h
Charging is a cracking issue for electrified vehicles. Renault project Incit-EV evaluates seven alternatives for future charging. Among the methods is dynamic charging at highway speed.
Mobile charging robot
Equipping parking spaces with charging points for electric cars is an extensive task. Volkswagen now presents a mobile charging robot that takes electrical energy to the car without cables. Volkswagen's solution consists of two units: A robot that opens the charging cap on the car, places the cable, and takes it out again when charging is completed. In a tow train, the robot has a mobile storage device with a battery of about 25 kilowatt-hours. The driver orders a charge via an app or via so-called Car-to-X communication. After the robot has paired a car with a storage unit, it can roll on and pair another car with another storage unit.
How big tank do you have in your car? Most fossil car owners have not answered that question. The reason is that a fully functioning infrastructure of garbage in combination with a reasonably large tank and sufficiently efficient engine has erased the concern for the Soppatorian.
But for electric cars it is different.
At present, the charging infrastructure is deficient, and the electric car market is quite immature. As the owner of a battery car, you often have to be able to charge at home for it to be manageable. But for many, this is not possible. So how can electric vehicles become a good alternative to cars with internal combustion engines?
This is where the European project Incit-EV comes in. The Renault Group stands behind 32 partners in Europe.
The purpose is to improve the user experience for electric motorists, as well as find solutions to meet most of the needs the market may have.
Contactless charging at 130 km / h
The project started in January and lasts for 48 months, with the first analysis period running until April 2020. In phase two, seven different demonstration projects are initiated, and towards the end of the period, the idea is that the technology solutions that can be scaled up with satisfactory results will be launched broadly.
So what techniques will be tested? Induction charging – both stationary and dynamic. Double-directional charging. Besides, they will also check a solution with high voltage charging.
In Paris, the consortium will test how dynamic charging can take place, in two separate projects.
The first is about inductive charging where two prototype cars, a passenger car and a van, are equipped to handle this.
An important part of the project is about seeing how an electric road can be integrated with the electricity grid, but also how the acceptance for this type of charging is – and the value of it.
A third project, which is happening in Versailles, is about being able to charge vehicles at highway speed. The idea is to get to a test track where cars can roll at 130 km/h and get contactless charging.
In Amsterdam and Utrecht, bidirectional charging applies. There the focus will be on a system where carpool cars are used in a vehicle-to-grid (V2G) solution. The purpose is that technology can lead to a system for smart energy use.
In Zaragoza, a project for bidirectional charging will be run. But this is about low voltage where two-wheelers are also involved. At the city’s airport as well as the central station, experiments are also started with dynamic charging in taxi files.
Also, a high-voltage system is being built on the outskirts of Tallinn. In one of Turin’s suburbs, a charging station will be tested at car parking lots.
