  • Tesla Wants to Build a Battery for Your House

    I read about this in a Norwegian newspaper this morning.

    “We are going to unveil the Tesla home battery, the consumer battery that would be for use in people’s houses or businesses fairly soon,” Chief Executive Officer Elon Musk said during an earnings conference call with analysts Wednesday.
    Combining solar panels with large, efficient batteries could allow some homeowners to avoid buying electricity from utilities. Morgan Stanley said last year that Tesla’s energy-storage product could be “disruptive” in the U.S. and in Europe as customers seek to avoid utility fees by going “off-grid.” Musk said the product unveiling would occur within the next month or two.
    “We have the design done, and it should start going into production in about six months or so,” Musk said. “It’s really great.”
    Tesla already offers residential energy-storage units to select customers through SolarCity Corp., the solar-power company that lists Musk as its chairman and biggest shareholder. Tesla’s Fremont, California, factory is also making larger stationary storage systems for businesses and utility clients. The Palo Alto, California-based automaker has installed a storage unit at its Tejon Ranch Supercharger station off Interstate 5 in Southern California and has several other commercial installations in the field.

    You can't find it because until something concrete comes out it is more vaporware from Musk who is one of the masters of vaporware.

        Ok, that just feels strange here in Oslo, where Tesla model S is a common car and amoung top sellers of all car models in periods.

        Some owners have passed 100.000km driving distance most of this on "free" electricity and consuming 250wh/km.

        I would very much like a 10kw batteribank if it can compete with my AGM 800kg massive battery bank

          Not if it cost you $1/wh you won't.

            Tesla Battery

            Is the plan to use the battery in the Tesla Cars as the storage unit and back feed the house on emergency basis or a total separate battery pack that resides in the house?

              I think you should be able to use it either off-grid or in a hybrid/grid-tie. Go Tesla, hope they nail it at a competitive price, but chances are it will be on the expensive side when it eventually get to market, cheers.

                Most Tesla's in the U.S. are not powered by "electricity'. They are in fact powered by coal.

                Electricity is just the means....

                A "Battery" cannot power your car or home..

                Whats in it powers your car or home... and how did "it" get there?

                Most greenies are so clueless...

                  The plan is to sell stationary battery packs to both homes and utilities.

                  Tesla's claim is that by cranking up the manufacturing volume of lithium batteries on a massive scale, they can bring down the price by a big fraction (like half or more). I have no idea if this will work or not, but at least they're putting their money where their mouth is.

                  I also saw a recent article (sorry, no link) that Tesla is planning to bid on some utility-scale battery storage projects which would be installed in California in five years or so.

                  Since the battery factory in question is still under construction, and the cars get first dibs on the output, it will probably be 3-5 years before you can buy a Tesla battery for your home.

                    Tesla uses LiCo cell, sames as in your laptop that requires extensive battery and thermal management that requires liquid cooling. Way too expensive and dangerous.

                      Thank for the Information.

                      With grid tie system everything goes dead when power goes down. Off grid with battery system is expensive. Option for backup system without paying a fortune is interesting.

                      Is anyone familiar with the concept of using the Prius hybrid car Battery and car generator as an emergency generator system?

                      There is an internet reference for something called a Plug out kits. http://www.converdant.biz/plug-out/

                        True, but for that price you get the whole car, the non battery stuff probably do have some value?

                        If you search the Tesla forums you will see that price estimations for the 85kwh batteri of a Tesla goes from 45000$ all the way down to 12000$. This is replacement prices so not the same as buying a separate unit

                        From a Tesla forum:
                        "Nissan has just announced a $5500 replacement charge for the 24kWh battery so it's reasonable to expect to get a 85kWh battery for (way) under $20,000 in the future."

                        0.25$/wh should be interesting when knowing you could use all the watts.

                          But you cannot buy them for that price, that is dealer cost and you must own a Tesla or Leaf and have a battery to trade in. Secondly last thing you want is a large LiCo battery in your house or garage. LiCo is a short lived battery. LFP is the long lived safe battery.

                            Presumably this price has some sort of trade-in allowance or even direct subsidy built in. Nissan wants to make sure buyers don't get too scared by the prospect of replacing the battery at some point.

                            That said, there are a lot of smart people in the EV business who think the price of battery packs is going to drop a lot in the next few years, and auto manufacturing can drive efficiencies of scale like few other industries. I wouldn't be surprised if there's already more kWh of battery packs in electric cars than in all the off-grid homes on the planet.

                            (Plausibility check: From Wikipedia, Tesla has sold 56,782 Model S sedans through the end of 2014, so this model alone represents between 3.4MWh and 4.8MWh of installed battery capacity. Also from Wikipedia, in 2007 there were 180,000 off-grid families in the U.S., but no word on what percentage of them have battery storage or how much; if they average 10kWh of battery storage, this would be 1.8MWh total. So the notion that there may be more battery capacity in EVs than in off-grid homes is at least not laughably wrong.)
