After rising for the last few years, the percentage of EVs sold in the UK has dropped from 16.6% to 16.5% from the latest figures released a few days ago. Reasons given are the high purchase price, the introduction of road tax on them coming shortly, the shortage of charging infrastructure and the cost of charging anywhere other than at home are what are putting off private buyers. I read a review of one that was taken on a family holiday around France recently (I think it was in Autocar and was a test of a BMW X5 EV) and the costs of charging at public charging points worked out at almost the same as I would pay doing a similar trip on LPG (and a P38 isn't exactly the most economical vehicle on the road) but one part that I wasn't aware of was the reduced range when cruising at motorway speeds. The reviewer said he had been getting a range of around 230 miles when cruising at 65mph but on his return wasted so much time looking for a working charger that he drove to the ferry at Calais at the legal limit of 80mph (130kph) and was down to 10% charge after only 140 miles. Now I would probably go further on a tank of fuel if I drove at 65mph but my consumption at 75-80 is still better than I get running around town and I get to where I'm going a lot quicker on a 500 mile journey.
As for Aus, my other half works for Cummins, the truck and ship engine makers, and they have sold a large number of diesel generator sets to Aus to power EV charge points away from the cities. So instead of a car generating pollution , it is simply moved to the means of charging. They have also developed a fully functioning Hydrogen engine for trucks, as have Mercedes, so the haulage industry seem to be ignoring EV technology. We also have an increasing number of trucks running on LPG and CNG.
I'm with you, an EV for someone that only drives in the city and charges at home, makes perfect sense. My sister has one but will be moving house soon to a more rural area and is looking at changing for a hybrid as the range on her current car simply won't be sufficient. Although, as she put it, her husband has a real car so if they need to go any distance, they use that.
