TBH, it’s all about whether you can charge at home and how often you do long runs.
The 194 mile journey you describe would be no problem in my Hyundai Kona EV. I wouldn’t be flapping or worried about making it. If I estimated a conservative 4 miles per kWh then that journey would use 48.5 kWh. At my nearly at an end Octopus Go tariff of 7.5p per kWh that would cost me £3.64. At my due to start Go tariff of 9.5p that would be £4.60. A significant saving I’m sure you would agree.
The only downside is that I wouldn’t be able to replace that 48.5 kWh all in one go due to the tariff’s 4 hour cheap rate window and the home charger speed. I would need to charge over 2 days to completely recharge which wouldn’t be an issue to me as I don’t do that sort of run regularly in quick succession.
Hope this is useful, Gary. In 3 years time I’m sure that battery capacities will be better again and longer runs will be even easier. The bigger issue for higher mileage drivers will probably be the slow speed of home charging and the high costs of public charging.
