Research conducted by Ohme has found that smart charging allows electric vehicles (EVs) to achieve the equivalent of 350mpg in an internal combustion (ICE) car.
Ohme found that a typical petrol car will drive 40 miles on a gallon of fuel, which costs £6.17, while EVs can drive 350 miles for the same price when smart charging.
Smart charging allows EVs to take advantage of lower off-peak energy costs.
An Audi A6 Avant e-tron with a 75.8kWh battery can be charged from 0% to 100% for £5.31, when using an Ohme smart charger with a dynamic tariff, such as Intelligent Octopus Go.
When charging with the Standard Variable Tariff, which costs 27.69p per kWh as of 1st January, a full charge on an A6 Avant e-tron would cost £20.99.
David Watson, CEO at Ohme, said: “The idea of a car doing 350mpg would obviously be fanciful, but that could be the reality when charging your EV on a smart energy tariff at home with Ohme.
“Charging at home will always be the most affordable place for EV drivers to charge their cars even with this latest rise and changing to a smart electricity tariff will enable drivers to maximise those savings still further.”
