Nissan and Nichicon team up to use Leaf battery to power home

( -- Recently Nissan announced its “Leaf to Home” technology, which is a device that attaches to a Nissan Leaf electric automobile allowing power to move both to the car’s battery and from it. Now Nichicon Corporation is announcing that it has built a device in partnership with Nissan, called the "EV Power Station" that takes power from the “Leaf to Home” device and makes it available to the home’s power system. In addition, it also serves as a charger for the Leaf, reducing the time it takes to charge the car’s battery from eight hours to just four.

The idea the two companies said in a joint news release is to give customers more power options. Because prices for electricity vary depending on demand, it makes sense for homeowners to charge their vehicles when prices are lowest, typically at night. And because quite often cars are left sitting idly in the driveway or garage once its owner has arrived home for work, it would seem wasteful to not use the battery in it to supply power to the house during the time when electricity rates are typically at their highest. That’s what the two systems allow.

Initially the dual system technology will only be sold to customers in Japan, where electricity prices have begun to climb in the wake of a nationwide shutdown of nuclear power plants following the Fukushima plant disaster last year. Particularly noticeable is the huge difference in electricity costs during different time periods, leading many Japanese electronics companies to develop and sell devices that are capable of taking advantage of lower price times. The company also points out that due to the same electrical supply issues, residential customers have had to endure more blackouts and brownouts than they have in the past. The new system they say, could be a tremendous help in such situations as they say the Leaf when fully charged, is capable of supplying up to two full days of power to a house using a typical amount of electricity.

The cost for the new system, which is expected to be made available in dealer showrooms next month, will be 330,000 yen (about $4,100) after subsidies, though not mentioned in the news release is how much it might cost the typical buyer to hook the system into their existing home electrical system.

What would this do to the cycle life of the battery? Could this be faults economy? Add to that the initial $4k cost of the charger system (I would think that a regular charger would be somewhat cheaper), then peak electrical rates would have to be very high to justify this setup.

Does anyone here have a variable power rate based on time of day at their residence (aside from Japan which is referenced in the article)? I know it is very common in the US for large facilities to have peak and off-peak rates. I have only lived in PA and NJ in the US in single family homes (a likely target market for this system) where I've seen a complete bill. I've never had an option of a rate that varied between day and night, just a single fixed rate or a day-to-day variable rate. I'm just curious if the primary argument for this system holds water in any of the target markets of the vehicle.

My local Phoenix, AZ power company, SRP, offers 2 TOU plans. See here: http://www.srpnet...q.aspx#1
One is 1 to 8 pm on-peak, another is 3 to 6 pm. (This is in summer.) The price differences are staggering, as in 6.65 cents per KWH vs. 21.30 cents on-peak. (Vs. roughly 11 cents on the Basic plan). Time shifting could save someone money if done intelligently, but there are a lot of variables...

If the car batt. could run the house AC, which here is the largest load by far, it could make sense. In this locale the AC is the hardest thing to not use during on-peak; for example it is 113 deg. today and even after precooling the house off-peak right up to the cutoff, it would be 90 deg. in here by the time the on-peak period ended. I've tried it, and it is hard. Everything else can be delayed/rescheduled, but not the AC in this climate. So for example, even though this is not a big house, I'd still need 5 KW available for 30 minutes out of every hour during the on-peak period. (20 amps at 240VAC to run the AC and air handler.) Can the Leaf do that and then recharge after 8 pm? I don't know...
