The cost of ultra-rapid charging (+101kW) is falling in the UK. This is particularly important for many high mileage users without access to their own charger. These prices are now below the costs of running a petrol car which is an important milestone is convincing the public to make the switch. In order for mass adoption, we need access to a broad range of changing speeds according to the dwell time of drivers. This ranges from overnight on-street, workplace and destination charging through to on-the-move rapid or ultra-rapid charging. 

It's therefore interesting to see that ultra-rapid charging is generally cheaper then fast (8-22kW) and rapid charging (23-100kW). Ultra-rapid chargers have the ability to sell many more times the energy compared to slower chargers and despite higher upfront costs, they can benefit from those economies of scale. The tricky part in attracting the public to make the switch will be the higher prices of fast and rapid chargers. However the rise of off-peak tariffs should make a positive difference in bringing these closer in line with costs of petrol. Of course there are many of cost of ownership benefits of EVs compared to ICE vehicles which very often help to tip the balance in favour EVs. 

I'm very fortunate to have access to my own charger and can benefit from intelligent off-peak tariffs making charging as little as 2.5p per mile. More and more energy companies are now offering intelligent off-peak tariffs for EV drivers with Octopus and Ovo seemingly leading the way. I'm always keen to hear from others on the innovative ways to charge in the cheapest way possible. Also with access to super cheap charging when will we see more V2Home applications for peak time home usage?
