2. Yes you read it Right!
Consider a future in which a driverless ridesharing electric vehicle (EV) pulls over as you exit a building,
takes you to your destination, and proceeds to drive passenger after passenger without ever needing to
stop to recharge its battery. Instead, power generated by nearby wind and solar resources is delivered
wirelessly from the roadway to the vehicle while it is in motion.
Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET),
or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link.
In a wireless power transmission system, a transmitter device, driven by electric power from a power
source, generates a time-varying electromagnetic field, which transmits power across space to a receiver
device, which extracts power from the field and supplies it to an electrical load.
The technology of wireless power transmission can eliminate the use of the wires and batteries, thus
increasing the mobility, convenience, and safety of an electronic device for all users. Wireless power
transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or
are not possible.
3. Where are we?
All WPT technologies are currently under active research, much of it focused on maximizing power
transfer efficiency and investigating techniques for magnetic resonant coupling. In addition to the idea of
walking into a room equipped for WPT and having your devices charge automatically, much more
ambitious projects are in place.
Across the globe, electric buses are becoming the norm; London's iconic double-decker buses are planning
for wireless charging, as are bus systems in South Korea, Utah, and Germany.
Using WiTricity, invented by MIT scientists, electric cars can be charged wirelessly, and those cars
can wirelessly charge your mobiles! (Using Qi charging, of course!) This wireless technology is convenient,
to be sure, but it may also charge cars faster than plug-in charging can.

5. Concept of WPT infrastructure :
❑ Wireless Charging through Road
❑ 3D printed road with charging coils
❑ Coil Supply through Solar / Wind
❑ Stretches can be repeated every
100KM
❑ Intelligent charging systems will
automatically take cars in need of
charging in Systair Charging lane.
❑ System will automatically charge the
car bill system on units consumed.
8. The Technology
The important aspect in the WPT design with inductive coupling method is the range between coupling
device, transmission signal frequency and inductance. Selected wire diameter, coil diameter and the ratio
of coil turn number are chosen according to the inductive coupling observation based on electromagnetic
field. Measured voltage, current and power were also investigated. The mechanism of energy transfer is
conducted by exploration of electrical characteristic between transmitter and receiver, respectively.
Capacitive WPT systems have potential advantages over the inductive systems because of the relatively
directed nature of electric fields, which reduces the need for electromagnetic field shielding. Also, because
capacitive WPT systems do not use ferrites, they can be operated at higher frequencies, allowing them to
be smaller and less expensive. Capacitive WPT could thus make dynamic EV charging a reality
9. Challenges :
❑ Health effects of long-term exposure to weak electric and magnetic fields,
❑ Mechanisms to detect living and foreign objects in the proximity of WPT systems,
❑ Methods to determine optimal charger power levels and spacing for cost effectiveness,
❑ Techniques to embed WPT technology in roadways e.g. 3D printed roads
❑ Approaches to analyze impacts of large-scale WPT system deployment on the electric grid.
❑ Mass production of EV’s with coils
❑ Renewable infrastructure across road network
❑ Intelligent charging Car Vehicle system based of IoT
10. Incentivize charging infrastructure
BIM is taking hold in transportation projects thanks to positive bottom-line results. The coordinated
model ensures that projects run efficiently, stakeholder communication helps eliminate costly rework, and
project outcomes are met in a timely and cost-effective manner.
The movement toward building information modeling (BIM) for transportation projects has proponents
around the globe, but it has yet to expand into widespread adopt The BIM approach centers around an
intelligent model shared across team members, acting as a collaborative hub throughout the entire
lifecycle of an asset.
The model can start at asset conception or later via highly detailed and automated data-capture
technologies. The model gains intelligence as it gets passed among different practitioners who add their
expertise, document conditions, or add operations and maintenance actions. The well-documented work
assists and improves operations while reducing costsion. The game-changing processes and workflows
start when companies adopt BIM tools to create a business advantage as well as differentiate and market
themselves against competitors.
11. Incentivise charging infrastructure
The majority of charging infrastructure installations and projects will not require lengthy planning processes and consultation, there
is an opportunity for the government to invest in the e-mobility sector through incentives and capital projects delivered locally
through local authorities and devolved administrations.
While short-term it is likely to have a stimulus effect of increasing jobs/retaining jobs in the construction sector, there are also
arguably long-term amenity benefits through cleaner air and reduced noise pollution, as well as tangible economic benefits from the
reduction total cost of ownership and gains in productivity. In AEC, we're on the cusp of the same transformation. Ours won't be self-
driving cars but large-scale design automation.
12. High-performance, safe, and cost-effective dynamic electric vehicle charging has the potential to revolutionize road
transportation as we know it!
