The Nissan Leaf allows the energy of its battery to be resold to EDF to earn money


The Nissan Leaf is a fairly widespread electric car in Europe. Also in the US, and it’s one of the few cars to have two-way charging. Nissan announces the possibility of connecting the car to the electricity grid to sell the electricity from its battery at a high price.

Bidirectional charging is increasingly present in electric cars, including the Kia EV6, the MG5 and the Ford F-150 Lightning pickup. This technology makes it possible to use the traction (lithium) battery of the electric car to power a device, such as a computer, a toaster or a site tool. But V2G (vehicle-to-grid) technology goes even further, since it returns electricity directly to the power grid.

A two-way charging station

In France, the Nissan Leaf is the only electric car still on sale compatible with this technology, as can be seen on the site of Izivia, the subsidiary of EDF. In practice, it suffices to install a special charging station, equipped with V2G compatibility. Thus, the one proposed by Izivia hasa power of 11 kW. This means that the battery can be charged and discharged at this power. Enough to to supply a house operating exclusively with electrical energy.

However, this functionality is a priori reserved for professionals, at least in Europe. Indeed, in the United States, V2G has just arrived, again through the Nissan Leaf. As we learn from the press release from the Japanese manufacturer, the Nissan Leaf will allow energy to be sent back to the electricity grid across the Atlantic thanks to a local partner who has developed a bidirectional charging station fora power of 14 kW.

Make money with your electric car? It’s possible !

In the United States, electricity network managers (the equivalent of RTE in France) can send energy requests to individuals and professionals in the event of high consumption, such as during heat waves or winter episodes. The objective is toencourage the energy from batteries and photovoltaic panels to be sent to the gridin exchange for attractive remuneration.

The American media Electrek takes the example of this summer’s heat wave, when 1 kWh of energy was bought for 3 dollars on the wholesale market in real time. Against less than 20 cents in normal times. Enough to send the equivalent of 186 dollars draining the 63 kWh battery while it takes barely 13 dollars to recharge it in normal times.

This means that it was possible to charge the battery of a Nissan Leaf before the event, then resell this energy during peak consumption for more than 10 times more. In France, EDF does not buy energy as expensively. But if you recharge on a free terminal and then resell the energy to EDF, then it can work.

Support and manage the electrical network

But in reality, the objective of V2G is not to make money, but rather to help the electricity network to pass the periods of peaks. Moreover, in its various energy scenarios, RTE relies heavily on V2G to relieve the network and thus store the energy produced by solar panels and wind turbines. This is called controlling electricity production.

And that’s exactly what Tesla and Nio are doing with their virtual power plants. The idea is to use batteries from photovoltaic panels and electric cars to power the electricity grid.

Apart from electric cars, what do the American Tesla and the Chinese Nio have in common? Their ability to build virtual power plants, in order to become energy providers. We explain how.
