Meet the electric cars that can charge other electric cars

New electric cars from Hyundai, Kia, and Ford will be able to help other stranded electric vehicles – by giving them a top-up with an extension cord.

There is now a solution for dead batteries in electric cars.

New technology enables certain examples to share their power with other electric cars, to give them a jump start if they run out of juice.

The latest electric cars from Hyundai, Kia and Ford have the ability to share their battery power with another vehicle that is running low and needs a bit of a boost.

One hour of charging from these electric vehicles should deliver enough energy to drive a stranded electric car between 10km and 20km (depending on the model).

This could be enough to get the stranded car to a nearby fast charger.

It’s the modern equivalent of assisting another motorist of a petrol or diesel car with a small can of fuel.

Except in this instance, the electric car donating its power already has the spare energy on board – and no-one needs to fetch a fuel can.

Electric car manufacturers say vehicle-to-vehicle charging won’t become widespread, but it’s good to know the technology exists.

The new Hyundai Ioniq 5 and its twin, the jointly-developed Kia EV6, can power another electric car – or a lap top computer or a food mixer.

The Ford F-150 Lightning pick-up in the US can run power tools, or charge a stranded electric car.

The charging rates on the Hyundai and Kia cars are 3.6kWh (which delivers 50 per cent faster charging power than a 2.3kWh household socket).

The Ford F-150 Lighting can recharge other vehicles at a rate of 7.2kWh or 9.6kWh when equipped with the right adaptors, which would deliver in excess of 30km driving range to a stranded electric car after an hour of charging.

To date, Tesla cars do not offer the ability to charge other electric vehicles.

Outlining the benefits of vehicle-to-vehicle charging, a statement from Ford said: “Just as (mobile) phones and the internet changed our way of life, electric vehicles are poised to do the same with a wide range of new services and features.”

Ford says the new F-150 Lightning – which is not planned to be sold in Australia – can also be used to power a home, during emergencies.

“Instead of installing a home generator or battery backup, the (Ford F-150 Lightning) can be used to power a typical-size home for up to three days in the event if a power outage,” says Ford.
