However, home and
workplace charging will still be
the ideal option for daily work
commuters and low mileage,
inner-city round trips. Enevoldson
stresses that It is important not to separate out
AC and DC in this discussion: “Adoption of EVs
needs people to adopt a new approach to
fueling their vehicle. The average car has been
shown to only spend 4% of time actually
driving. The rest of the time it is parked either
at home or work.
“Fueling should not be seen as a singular
event you do in the course of driving, but
something that is done when you are not in
need of transportation. Ensuring that
workplace AC chargers are widely available in
the UK – where 36% of commuters still travel
exclusively by car – will go a long way to
encouraging adoption and fi ghting off any
worries of range anxiety.”
increase of 1.6% in today’s utilities, which on
a macro basis could be managed through
existing planning processes.
Charging types
“Currently AC is king, but soon
the percentage of 50kW DC
rapid chargers will grow and
we will begin to see 100kW to
175kW DC charging capability
on the major networks as the
norm,” says Pugh. “Availability
of power is an important part of
the scaling up for charging
capability and accessibility across
the map, so combined leadership and
close relationships with grid and power
specialist will be the key to developing and
deploying the right solutions.”
Muehlon thinks DC charging is still too
powerful for most consumer vehicles right
now, “But all that may be about to change with
the launch of the fi rst consumer car capable of
taking over 175kW, the Porsche Taycan.”
Adrian Keen, CEO of InstaVolt, agrees,
and reveals that the company spoke with
car manufacturers to understand their EV
roadmaps. “From these conversations, it is our
view that the next generation of EVs will use
DC charging technology. Indeed, it is DC that
is best suited to delivering faster rates of
charging and we’re seeing this with the next
generation of vehicles coming to market.”
