Use your energy
If you generate your own renewable energy, we salute you – but why export up to 80% to the grid when you could use it yourself?

In a global first, electric vehicle drivers will be able to discharge power from their car’s battery pack to pay for parking when they visit the Nissan Pavilion.
The exhibition centre in Yokohama, Japan is a 10,000-square-metre, zero-emission complex fitted with solar panels and supplied with renewable hydroelectric power.
The process has been designed to showcase the Nissan LEAF electric car’s ‘Vehicle-to-Grid’ (V2G) charging capability, and gives a glimpse into how British companies will be able to save money from their fleets of electric cars.
The LEAF, which is built at Nissan’s Sunderland plant as well as in Japan, has bi-directional charging that allows power to be pulled from its battery as well as being supplied to it.
‘The Pavilion is a place where customers can see, feel, and be inspired by our near-future vision for society and mobility.
‘As the world shifts to electric mobility, EVs will be integrated into society in ways that go beyond just transportation.’

In this case, the Nissan Pavilion is absorbing electricity from the Nissan as a ‘parking fee’, but the LEAF family hatchback can also be used to supply energy to bricks and mortar closer to home.
It is estimated the 62kWh battery from a Nissan LEAF can power the average UK home for a week.
In the UK, Nissan has partnered with energy provider E.ON to explore the use of V2G charging.
The two companies have successfully installed 20 V2G chargers at the car manufacturer’s European Technical Centre in Cranfield, Bedfordshire.
It demonstrates how storing and sharing electricity in fleet vehicles’ batteries can generate additional revenue for participating companies as well as supporting the power grid.
The project, co-funded by Innovate UK, allows energy stored in car batteries to be sold back to the grid when demand for power is high.
Vehicles can then charge when demand is lower or renewable generation is high, reducing reliance on fossil-fuelled generation and giving V2G a role in carbon reduction efforts.
If you generate your own renewable energy, we salute you – but why export up to 80% to the grid when you could use it yourself?
This clever piece of kit can provide a green – and sometimes free – charge for your EV.
£1.2m investment from two of the UK’s most influential businessmen will help myenergi give power back to the people.
Drivers could be paid for using their electric car batteries to support the power network.
