Preorders for the xStorage battery will begin in September. There were no details about the actual size of the xStorage product on either vendor's site, but from photographs, it appears to be about the same size as Tesla's Powerwall battery.
The Powerwall battery, which is 51.3-in. x 34-in. x 7.2-in., is already shipping to customers who reserved it early through Tesla Energy, a subsidiary of Tesla Motors. Tesla is constructing a massive Gigafactory to build the batteries just outside of Reno, Nevada. The factory, which will also build batteries for Tesla's all-electric vehicles, is already producing Powerwall batteries.
Both the Powerwall and the new xStorage battery are aimed at storing electricity from a grid or from renewable sources, such as solar panels. During the night, or when utility rates are low, or during a power outage, the batteries would power a home.
Unlike Tesla, which will sell its batteries through 10-year-old SolarCity, Nissan and Eaton are manufacturing giants with more than 100 years of experience each in selling products around the globe. The xStorage batteries were designed in the UK at Nissan Design Europe in London.
The companies did not specify whether they would sell the batteries in the North American market. Nissan and Eaton officials could not immediately be reached for comment.
Like Nissan, Eaton is an enormous corporation, with 97,000 employees and revenue that topped $20.9 billion last year. Founded as a U.S. company in 1922, but based in Dublin today, Eaton makes a variety of products, including circuit breakers, electrical invertors, sensors, relays and UPS systems, that are sold in 175 countries.
Nissan and Eaton said they expect sales of the xStorage batteries to exceed 100,000 units within the next five years.
"It is high time consumers were given the flexibility and power to control how and when they use energy in their own homes," Paul Willcox, chairman of Nissan Europe said in a statement. "The new xStorage solution combines Nissan's expertise in vehicle design and reliable battery technology with Eaton's leadership in power quality and electronics, resulting in a formidable second life battery solution."
