DRIVERS travelling between Australia's major cities could soon charge their electric vehicles in just 15 minutes with a super-fast network being rolled out across the country.

The 21 sites on highways between Adelaide, Melbourne, Canberra, Sydney and Brisbane will be powered entirely by renewable energy. Sites are also planned for Western Australia.

The "ultra rapid" stations will allow electric vehicles to add up to 400km of range in a fraction of the hours it takes to charge at existing points.

Australian start-up Chargefox raised $15 million to start building the network, including $6 million from the federal government's Australian Renewable Energy Agency.

Tesla introduced a new $45,000 version of its Model 3 sedan on its website, launching the car as U.S. tax breaks for Tesla cars are about to decrease.

ARENA chief executive Darren Miller said it was a "game changing" project that would help ease worries about range and encourage more people to drive electric vehicles.

"This network will help alleviate that concern by giving motorists comfort they can travel long distances," he said in a statement on Monday.

"Electrification of Australia's transport sector could reduce emissions and dramatically change how we use electricity."

The first two charging sites will be in Euroa in Victoria and in Barnawartha North just outside Albury-Wodonga on the Victoria-NSW border.
