--- Quote from: woodchips on February 15, 2020, 11:07:00 am ---There was an interesting article on The Times website https://www.thetimes.co.uk/article/confessions-of-an-electric-car-virgin-fq3lsz8tv about driving a Nissan Leaf 1000 miles from London to Edinburgh and back. What was unusual was that it itemised the cost of recharging. Unfortunately the link seems to have lost this vital info, unless someone knows better. But, he apparently spent £130 on electricity at charging points. --- End quote --- The article look interesting but is paywalled. £130 seems excessive but plausible. If he drove with a heavy right foot on motorways all the time and the heating on flat out he might get as little as 2.5 miles per kWh in a leaf (guessing here, I get about 3.7 in a Zoe in midwinter with a mix of urban and motorway driving). 1000 miles is then 400 kWh which would suggest he was paying £0.32 per kWh. That's perhaps believable if he only charged at those silly-expensive ecotricity-owned motorway chargers. Alternately he may be counting some other costs, like that a lot of charging networks require you to load a minimum amount of around £10 onto their app before you can use their chargers. TLDR: I can believe he spent £130 but I think the journey should be possible at closer to £40-50. |

It would be interesting if you could post a bit more data from that article. I often use http://abetterrouteplanner.com to get good guesstimates for my EV trips. If I enter a return trip in a 2018 40 kWh Leaf, I get a trip of 1289 km using 203 Wh/km = 262 kWh. Charging is done on Chademo stations, like from the ecotricity.co.uk network. They charge 30p per kWh. (15p if you're already a customer apparantly.) So that adds up to 78.6 UKP. That is indeed a lot! If you were to use a Tesla model 3 using the Tesla supercharger network, it would cost around 49 UKP according to the same site. --- Quote ---And does hydrogen work? --- End quote --- There are a few.

This year they expect to sell close to 200. That is pretty similar to when electric cars where first introduced. Give it time. I see myself buying a hydrogen car rather than an EV because I can't charge it from my own outlet and are likely to depend on whatever company is going to exploit the charging point in the street. A hydrogen car doesn't need a very dense infrastructure in order to be useable. In the (relatively small) city I live in there are 15 to 20 gas stations. If there is one hydrogen filling station nearby then that would be good enough to make a hydrogen car useful. Germany and Denmark seem to already have a useable hydrogen filling infrastructure. In the long run there will some competition too so the prices can't be jacked up to insane levels. Then again.. I expect my next car to be a hybrid in a couple of years. |
