Nikki Gordon-Bloomfield, Founder and Lead Presenter, Transport Evolved gave this presentation at the induction charging webinar on February 23, 2021

1. WIRELESS EV CHARGING
Misconceptions and Myths

2. 14 Years, 12 Plug-ins
(plus some stuff that doesn’t count)

3. EARLY TESTER

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!
It will help EV adoption

Percent
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.
