Nissan’s global head of electric vehicles Nic Thomas has labelled Tesla’s big battery in South Australia as a “complete waste of resources” in a recent interview with The Driven.

“It’s [Tesla’s big battery] a complete waste of resources because what we can do is have cars that are also batteries and those cars are parked most of the time,” Thomas said.

It’s a controversial statement, as Tesla’s Hornsdale battery has been widely admired as a success for the performance of the grid and finance-wise.

Mr Thomas made the comments during the launch of the all-electric 40kWh Nissan Leaf in Melbourne, discussing the LEAF’s vehicle-to-grid/vehicle-to-home system, which will allow the two-way transfer of energy between the car and the home.

The Leaf has the potential to become homes’ personal mobile battery that can charge when parked, storing energy for later use at peak times.

Jetcharge CEO Tim Washington said cars will become an energy asset first and a mobility asset second.

“What I mean by that is you are going to use your cars probably more as batteries than as vehicles,” he said.

“As we know vehicles are parked 90 per cent of the time – that is one of the criticism levelled at cars. But what if they are the most efficient asset that you have because it’s doing work even when it’s parked?”

The technology has been spruiked as having the option to charge off rooftop solar during the day (providing you don’t use your car for work) and then using the stored energy at night, or charging at off-peak rates overnight for use in the day. It can also be charged at DC fast-charging stations for home use.
