Nissan reveals its answer to Tesla's Powerwall battery system for the home

Categories: Energy

Nissan's grand designs for zero-emission cities of the future may be some way off, but you gotta start somewhere. And that somewhere starts with "xStorage," the automaker's home energy hoarding system announced a couple of weeks ago. Like Tesla's Powerwall and Mercedes' residential battery, the idea is to save you money in the long run by charging the thing up when off-peak electricity rates are in effect.


You can then use the cache to power your home when energy is more expensive -- switching between sources by way of smartphone app -- or sell it back to the grid during these times of higher demand. And if you can juice the xStorage unit up using a renewable source like solar, then all the greener.

Auto brand Nissan has created an energy storage system for the home using a recycled car battery, and announced plans for a trial in the UK that will allow electric vehicle owners to sell power back to the grid.

Nissan announced its vehicle-to-grid (V2G) trial – the first of its kind in the UK – at an event in London yesterday before revealing a slim wall-mounted battery pack for the home called xStorage.

One hundred V2G units will be installed across the country for the trial, where owners of the Nissan LEAF car and e-NV200 electric van will be able to plug their vehicles in and sell stored energy back to the National Grid.

This model could, if scaled up, provide a stable energy infrastructure in the future, according to Nissan and power company Enel.

Nissan is differentiating itself from competitors by using old EV batteries in its xStorage units, making them as environmentally friendly as possible. The company has been breathing new life into used batteries before now, partnering with businesses on commercial energy storage projects. The new xStorage system will be Nissan's first foray into the residential market, however, when pre-orders kick off in September. There currently aren't any plans to bring the home battery to the US, but in Europe, an xStorage unit (holding roughly 4.2kWh of electricity) will set you back €4,000/£3,200 (around $4,500) including all installation costs.

Nissan also announced a major new trial of its vehicle-to-grid (V2G) systemin the UK today. Still in its early stages, V2G promises exactly the same benefits as a home energy storage system, but it hooks up to the battery in your EV instead. Following a smaller test of the technology in Denmark that began in January this year, the UK trial will include 100 Leaf and e-NV200 vehicles owned by both private and commercial customers.

Vehicle-to-Grid technology will put energy management back in the hands of the people by turning their Nissan electric vehicles into mobile energy hubs. Using the innovative Vehicle-to-Grid technology developed in partnership with ENEL, drivers can store electricity in their vehicle’s battery and return it back to the grid when needed.

Vehicle 2 Grid originates from our experience in the field of infrastructure and e-mobility management systems combined with that of Nissan, which manufactured Leaf, the electric car that is most sold in the world.
