I could come up with many reasons why you shouldn’t order an electric car…. but there are so many more reasons for not ordering a fossil that I’ll not bother.
Oil companies such as Shell charge 41p/kWh, the VW/EU funded Ionity comes in at a cool 69p/kWh (I pay 58p/kWh or would if I used Ionity chargers), BP will sting you for 42p/kWh although with the freebie BP Pulse/Polar card the rates are 12p/kWh@7kW, 15p/kWh@50kW, 27p/kWh@the 77kW max you’ll get on the Kona.
Some supermarkets give free charging, often 7kW, some CCS chargers give free vends especially just after being installed.
However, the costs don’t really matter as long as they’re cheaper than petrol/diesel, but using off peak electricity from wind & solar to charge your car matters very much so enjoy reducing your carbon footprint.
