Nissan's xStorage is its take on Tesla's Powerwall battery
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 today. 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.
Nissan wants you to use its Leaf EV like a Tesla Powerwall
In May, Tesla explained why it's a good idea to put multi-kWh batteries our homes. Half a year on, Nissan has worked out how to use the multi-kWh battery inside its Leaf EV in the same way. It's teamed up with the energy company ENEL to debut a "Vehicle 2 Grid" (V2G) system that allows electric vehicles as mobile power plants for homes, offices or returning energy to the grid.
