Some electric vehicles should be banned from using motorway chargepoints because they take too long to top up, according to a new report.
Slower-charging plug-in hybrids are blocking equipment which is essential to battery-only vehicles making long journeys, a study for the RAC Foundation warned.
The latest battery-only cars need just five minutes at the quickest chargepoints to add 15 miles to their range, compared with an hour for almost all plug-in hybrids to achieve the same benefit.
Battery-only cars have no combustion engine, while plug-in hybrids can operate in full electric mode, using conventional fuel or a combination of both.
Report author Harold Dermott, who has spent more than 35 years in the motor manufacturing industry, claimed confusion over how fast different electric vehicles can be topped up could undermine efforts to provide an adequate public charging network.
