This linked article from another thread highlights how much roadside charging infrastructure is needed right across the country yet as far as I know
nothing is even planned.
While most manufacturers will offer longer range models this comes with cost, space and weight penalties. I think those who only occasionally make journeys that can not be completed on a single charge will just accept the time to stop and charge plus the cost surcharge over home charging. But they will expect chargers to be available without queuing.
Before I have referenced the Vauxhall E-Mokka solely because of the
range simulator.
This gives 209 miles at 40mph, 186 miles at 50mph, 156 miles at 60 mph and 127 miles at 70mph.
These of course are the maximum. Allow 20 miles contingency plus fast charging to 80% then the latter two become 109 and 85 miles
If by 2030 the standard battery is 25% higher capacity then 142 and 111 miles.
Neither consider battery capacity reduction with ageing.
Motorways will need charging stations on each carriageway with 500+ 100kW chargers every 12 - 15 miles. For major roads e.g. A34 Winchester <> M40, A14 M1 <> Cambridge either 250+ chargers each carriageway or a single station with 500+ chargers.
Towns and cities will also need car parks where a significant number of bays have a charger of say 15kW. The proportion perhaps higher in a tourist destination e.g. Whitby.
To supply these chargers new feeds will be needed from the national grid.
In the estate where I live there are blocks of flats and some houses with no parking where they can charge fed from the flat / house. Hence shared use chargers are needed where cars can be left connected programmed to charge overnight at a tariff compatible to those who can have a charger connected to their home electricity supply.
So again to the thread title
Do you think that the UK switching to electric vehicles is realistic? answer Yes but with 7 years until 2030 and manufacturers planning to end ICE car production around 2028
large scale action is needed starting now.
