Electric vehicles without power should not be towed to charge points

Towing is not suitable for EVs

All wheels should ideally be off the ground when moving EVs from point to point. But now a diesel rescue van can generate enough of a boost charge to enable stranded drivers to get to the nearest charge point in their own EV – in parts of the UK at least.

In readiness for the UK’s expected electric vehicle boom, the RAC has developed its EV Boost system – the first lightweight mobile EV-charger capable of giving stranded out-of-charge cars a power boost from one of its standard orange roadside rescue vans, says NextGreenCar.

The bespoke solution can be rolled-out to hundreds of patrol vehicles ensuring the RAC can match the scale of demand as electric vehicle ownership grows in the coming years.

The first six Ford Transit Custom patrol vans equipped with the new EV generators will take to the roads in June in London, Birmingham and Manchester and will be rolled-out to areas with high call-outs.

The charger, which was developed by the RAC’s technical experts in partnership with automotive engineering firm Original Ltd, is capable of delivering a ‘top-up’ roadside charge from a standard Euro 6 diesel RAC patrol van sufficient to get a stranded EV safely to a nearby charge point.

The RAC EV Boost charger works with all Type 1 and Type 2 connections ensuring it will charge 99% of electric vehicles on UK roads today.

EVs present a particular challenge as many cannot be towed normally and ideally should be transported with all wheels off the ground which usually requires a flat-bed vehicle. So, if an electric car runs out of charge in a busy urban location, such as a red route in London or even just a narrow road, it can’t be towed to the nearest charge point – and is likely to cause traffic jams and frustration.

RAC head of roadside rescue innovation Chris Millward said: “Our solution enables our patrols to help stranded EV drivers at the roadside with a power boost, equivalent to a top-up from a fuel can for a petrol or diesel car, to get them on their way again.

“With nothing like it on the market the real challenge was to develop a mobile EV-charger system which is compact and light enough to fit into our normal patrol vehicles without compromising on space so we can still carry all the normal parts and tools to help our patrols continue to fix four out of five vehicles at the roadside.

“Other solutions that are available require valuable van space to be taken up by heavy portable chargers that negatively affect fuel economy and also need to be recharged after use. Our on-demand solution means that the power is always available when needed.

“The number of electric vehicles on the road will grow rapidly in the next few years, in particular we are seeing increased interest and take-up from business and fleet managers, so it is critical that we have an effective mobile power source for these cars in an emergency giving EV-owners complete peace of mind. The new mobile RAC EV Boost charger has also been well received by our manufacturer partners.

“We also expect it will help address the anxiety some potential EV buyers have about the current charging infrastructure and vehicle range. The RAC is constantly looking to evolve and invest in technology to meet the changing needs of drivers and their modern vehicles, and this EV-charger fits perfectly with this strategy.”
