The problem with this lies outside the window. I just looked out to see a cold, wet world.In a 200 mile car that does say 150 genuine motorway miles with some charge left then it's adding on one charge period. I'd guess it would be 45 minutes. So best case is diesel plus an hour to allow for any charging delay.
On a normal EV then the only one around now is the Zoe. Can one of those do 150 miles in one go? Pick a rapid charge one then it will charge at 43kWh. I'd bet you'd need two stops anyway as they won't be quite in the right place and it's guaranteed range would be nibbled away at the wrong moment too.
There's always the absolute speed and charging time trade off. I'd think with a much faster charging car it would be quicker to cane it and stop more often than bimble along and stretch a leg to have a shorter charge time overall.
VW did not make decent diesels.The reality is that any decent diesel will top 60mpg at a steady 70mph quite easily.
It would still take 4.3 hours which would leave around 10 minutes spare before even going into tacho OT, let alone unregulated driving hours.
It would use around £25 of fuel.
All largely unaffected by climate conditions.
I assume you drive a black Leaf?Looking at my logs I managed over two years an average of 3.75 Miles per kWh at an average speed of 25mph
My fastest drive was an average of 59.08 mph and used 3.29 Miles per kWh.
The average of all my >50mph drives works out at 3.43 Miles per kWh
Interestingly my best Wh per mile I have logged over a decent distance was 51 miles at 183Wh/Mile (used 9.35 kWh), in the height of summer. All motorway. 73 degrees fahrenheit.
My worst wH per mile (over a distance) was 28.06 miles at 352wH/mile (total of 9.89 kWh) - in September. A-Roads. (54 degrees fahrenheit).
I have a log of a 385 mile round trip:
I used 87kWh of electricity at an average speed of 31.7 mph. Motorway and A Roads. Temperature 61 to 77 fahrenheit. 8 Charging stops (including a destination charge).
The best case was the return journey where I wanted to get home and obviously didn't have to worry about saving charge on the last leg:
Total Travel time of 6 hours to do 188 miles at an average of 40mph using 43kWh of electricity at 71-77 fahrenheit. Just two charging stops as they were perfectly placed.
