Tesla’s big battery in South Australia is a ‘complete waste of resources,’ claims Nissan



In a recent interview with the Australian automobile publication The DrivenNissan's global head of electric vehicles, Nic Thomas, shared a rather surprising insight into the large Tesla battery installation in South Australia, which is widely recognized for helping residents reduce their dependence on gas cartels that they operate in the region.

During the launch of a new version of its popular all-electric 40 kWh Leaf in Melbourne, the Nissan executive boldly stated that Tesla's Powerpack farm in South Australia is a waste of resources. "It's a complete waste of resources because what we can do is have cars that are also batteries and that are parked most of the time," said Thomas.

Thomas' statement comes while discussing the new Leaf / Vehicle Home Vehicle (V2G / V2H) system, which will allow the all-electric car to serve as a domestic battery unit. With the system in place, Leaf will not only store energy when connected to a home or business; The vehicle could also return the power when necessary. V2H is already in use in countries like Japan, and a launch in Australia is expected within six months.

The Nissan executive said Leaf's V2G system has the potential to help homeowners save money, especially if the vehicle loads through a rooftop solar system during the day, and uses stored energy to feed appliances and lights at night.

"The way we distribute and consume energy is fundamentally inefficient … what we need is flexibility in the system. "It's great that we have invested all this money in renewable energy, but fundamentally we are spending most of that energy because everything is generated in the middle of the day when we do not really need it," he said.

Tim Washington, CEO of the cargo solutions provider Jetcharge, said the Nissan V2H technology has great potential, considering that vehicles spend much of their time recently parked, or in the case of electric cars, plugged.

"Automobiles will be an energy asset first, and a mobility asset second. What I mean by this is that you are going to use your cars probably more as batteries than as vehicles. As we know, vehicles are parked 90% of the time, that's one of the criticisms of automobiles. But, what if they are the most efficient asset you have because it is working even when it is parked? That's when bidirectional loading comes into play, "he said.

While V2G technology has great potential that even Tesla CEO Elon Musk acknowledges, the casual dismissal of the Nissan executive from the Hornsdale Energy Reserve of 100MW / 129MWh in South Australia seems to be at the best of times. cases, uninformed. After being online, after all, the Powerpack farm, whose size equals around 2,500 Nissan Leafs of 40 kWh, has been widely acclaimed for its speed and sophistication.

Even before it was officially activated, the big battery was put into action, injecting 70 MW of wind energy stored in the market; And just two weeks after it went online, it intervened to support the network when a coal generator in the region failed. This rapid response, which has practically changed the game of power in South Australia, would probably be quite difficult to match with a fleet of Nissan Leafs. V2G definitely has its uses, and will be beneficial to the owners of Nissan Leaf; But ultimately, large batteries such as the Hornsdale Power Reserve are at a completely different energy storage level.
