The Flexibility
of Domestic
Electric Vehicle
Charging
The Electric Nation Project

ELECTRIC VEHICLES (EVs) ARE KEY TO THE DECARbonization
of the transportation sector. Take up is growing
rapidly and projected to continue. The utility companies
need to prepare to meet the additional demand that EV
charging will create. This article explains how flexibility in
EV charging could be a key enabler of the transition.
This article is based on the fi ndings of Electric Nation (a
Western Power Distribution project). The project, based in
the United Kingdom, included a two-year fi eld trial (beginning
in 2017) involving nearly 700 drivers with a wide range
of EVs. It proved the level of fl exibility in home EV charging
and exploited this fl exibility using smart charging to reduce
peak demand. Through extensive customer research, the
project also demonstrated the willingness of customers to
provide this fl exibility, including their attitudes toward using
apps and time-of-use (ToU) rewards.

This article demonstrates the high levels of fl exibility
available from domestic EV charging. It also shows
how smart charging can use this fl exibility to limit the
increases in peak demand due to EV charging. The customer
research results presented in this article show how
this can be achieved while ensuring that customer satisfaction
remains high.
The U.K. Context
The electrification of transportation is key to decarbonization
and improving local air quality. Vehicle manufacturers
are developing EV technology to improve the range of
vehicles available and reduce the cost to customers. Government
support remains strong in the United Kingdom,
with government grants/incentives available for the purchase
of new EVs; a preferential company car tax rate; and
the installation of charging infrastructure at home, in workplaces,
and in public places. Significant policy support has
been demonstrated through measures such as initiating a
ban on the sale of new internal combustion engine vehicles
