You've hit a very good point here. Just how much is your time worth per minute, and how often are you doing this 200 mile round trip? Once that is answered, if it is a regular occurrence, can you tell us what the average speed you achieve is for the full journey door-to-door each way? These are more important questions that often are missed, as 70mph will never be the average unless you start on the motorway, finish on the motorway and never have any congestion.
If you do the journey once per month, or 12 times per year and you need to charge once on the return leg for 20 minutes, that is a total of 4 hours per year. £22k will get you a 20 plated Ioniq 38kWh, with less than 6k miles on it, vs £26k for 68 plated Kona 64kWh with 15k miles on it and less warranty left. So if you keep it 7 years you'll have used 28 hours of time, or spent over £142 per hour, and if you want to be pessimistic and call it 36 hours for 7years, then it is £111 per hour. You need to deduct the cost of the charge put into the car, but that would likely be less than £60 per year.
These are just random figures for you since the first question isn't yet answered, and obviously if your journey is time sensitive or you just hate not moving won't help you a great deal. I just though it is nice to see, I don't personally know many people who are paid £111+ per hour, food for thought!
