The document discusses misconceptions about wireless electric vehicle (EV) charging, highlighting that while it appears convenient, it faces significant challenges including inefficiency, safety, and high costs for home use. Expectations about its widespread adoption are tempered by the need for better infrastructure and practicality, particularly in commercial settings. The focus should shift toward realistic implementations, such as fleet operations, before introducing wireless charging as a mainstream feature.

6. INITIAL REVIEW (2017)
• Difficult to position the car
• Convenient - but not in a domestic situation
• Garage heated up (due to first-generation technology)
• Slower than J1772 physical connection
• Price outweighed convenience for domestic installations
• Base/Car pairing required - No ad-hoc charging

It’s a waste of money
It’s cool and I want it!

What do you think of Wireless EV Charging?

9. EXPECTATIONS VS REALITY
• We’ll all be using wireless
charging at home
• It will help EV adoption
• Dynamic wireless charging
= unlimited range
• It’s costly
• Wireless charging in the home
doesn’t make sense
• There are much bigger hurdles
to overcome FIRST
• The ‘bathroom problem’
• It can make sense in public
locations, reduce theft

10. EXPECTATIONS VS REALITY
• It’s low-powered
• It’s inefficient
• It’s unsafe
• It’s for consumers who
don’t want to plug in
• DC levels of rapid charge now
available
• Total system efficiency on par with
DCQC (~97% or better)
• Modern resonance charging is
extremely safe
• It’s more useful to fleet operators

11. EXPECTATIONS VS REALITY
• Car companies are now
offering it
• It will never catch on
• It will make battery packs
smaller
• People aren’t ready to pay
a premium
• It will be integral to
autonomous vehicle fleets
• Larger batteries = less
strain on the pack

12. A MORE APPROPRIATE ROAD MAP
• Autonomous warehouses and large fleets first
• Taxi fleets
• On-street charging of public transit
• OEMs and on-street charging adoption as optional ‘premium’ feature AFTER wider EVSE
deployment and standardization (including ubiquitous payment system, reliable
infrastructure, faster charging)
• Autonomous private fleet for high-end cars
• Wider fleet, ubiquitous deployment (with physical connections at home)

13. OUR HOMEWORK
• Engage in realistic, appropriate
conversations about wireless charging
• Ignore the ‘flashy red herrings’
• Design for practicality in fleets before
‘wow factor’ for OEMs
• Focus on commercial deployments
and better ‘regular’ infrastructure
before confusing consumers further
• Talk about electric fuel.
