Some 98% of England’s motorway network is no more than 20 miles from an electric vehicle charge point, according to new research.
A study by motoring organisation the RAC Foundation found that the proportion of service stations offering the facility has risen to 72%.
It stated that the vast majority (92%) of the individual charge points are rapid, meaning batteries can be almost fully replenished in around half an hour.
When the analysis was extended to include major A roads managed by Highways England (HE), it was calculated that 82% of the strategic road network is within 20 miles of a charge point.
There are currently just over 20,000 battery-only vehicles licensed in the UK.
The report found that just 28% of the major road network in Scotland is within 20 miles of a charge point, and 45% in Wales.
Steve Gooding, director of the RAC Foundation, said: “Electric car drivers might still struggle to drive from Land’s End to John O’Groats but they can now travel from Southampton to Perth in a relatively straight line and be confident of being able to ‘fill up’ along the way.
“The growing charge point network is good news but there are important caveats.
“Though many of the charge points are rapid, it will still take about 30 minutes to fully replenish a battery. This is fine if you’re first in the queue but could be a challenge if the hoped-for take up of electric cars materialises and you’re stuck at the back of a very long line.”
Research previously published by the RAC Foundation suggested that a third of charge points in London were not working at any one time.
From next month the £5,000 subsidy for electric cars is being reduced and replaced by a tiered system.
Vehicles with a zero emission range of over 70 miles will be eligible for up to £4,500 while those with a shorter range – such as plug-in hybrids with a petrol or diesel engine – can receive £2,500.
