Tesla begins battery production for Powerwall and Tesla 3 at Gigafactory

If there is any company that has succeeded in capturing the public imagination, it is Tesla Motors. The electric vehicle (EV) and battery maker’s charismatic CEO Elon Musk has present a compelling if not dazzling vision of a future of decarbonized electricity and transportation, even if customers must sometimes wait months to years to purchase these products.

Today a portion of Tesla’s vision became reality, with Panasonic and Tesla beginning production of their “2170” cylindrical lithium-ion batteries at their “Gigafactory” in Reno, Nevada. These cells will be used in Tesla’s Powerwall 2 and Powerpack 2 battery products, as well as its Model 3 EVs.

Tesla notes that production for qualification began in December at the Gigafactory, which when complete will be the largest factory on earth. The mammoth building is being completed in phases so that production can being inside finished sections and expand later, and by 2018 the company expects the facility to be making 35 gigawatt-hours per year of battery cells. This is nearly equal to the current global combined battery production capacity.

At peak production, Tesla expects the Gigafactory to employ 6,500 workers.

In addition to the Nevada Gigafactory, Tesla is now in possession SolarCity’s solar cell and module Gigafactory in upstate New York, through its acquisition of the company. The Buffalo Gigafactory will also be run by Panasonic, and Tesla has forecast that production will begin in the summer of 2017.

    Every update of the factory is showing just how huge this is slated to become.

  • brucelee

    And what of the silevo technology, this was their edge and now they are everything to Panasonic tech?

    • neroden

      Not at all clear. Tesla’s official postition is that they are merging the Panasonic and Silevo technologies. Most people don’t believe them. I actually do believe them.

      Panasonic’s main problem: their product was too expensive.

      Silevo’s main problem: scaling up.

      Silevo’s most important patent was on using copper instead of silver. This saves a *lot* of money. Tesla’s being very secretive about their process, but I certainly hope they are using copper instead of silver.

      Silevo also had managed larger wafer tech than Panasonic and this was specifically mentioned as something they could do which Panasonic couldn’t.

    Is there a place to ask technical questions concerning the Powerwall 2? Like:
    What is the optimum input voltage from a off-grid solar array to the Powerwall 2?
    What is the optimum or suggested size of an off-grid solar array for one Powerwall 2?
    Can the Powerwall 2 be placed indoors without it being a fire hazard?
    Does the Powerwall 2 require lightning protection if indoors and hooked up to an off-grid solar array?
    What is included in the $1000 install kit?
    Does each Powerwall 2 require its’ own inverter when installing multiple Powerwall 2s?

      Powerwall 2 can be DC DC or AC AC it comes with its own inverter.
      It is expected to degrade to 70% of its starting labeled ability in 10 years.
      Has a 90% round trip efficiency.
      The temperature tolerance is available on the web site i forget it atm.
      From memory i think it performs best in a shaded environment.
      All electronic equipment needs lightning protection in any situation.
      The one aspect if find extremely hard to come to terms with is the extremely high cost of installation, if all is required is the 6 terminations and setting of the software to install.

      I asked the Tesla call centre for more info about using Powerwall 2 off grid, and their response was that they haven’t finalised anything in regards to compatible inverters or configurations, and won’t have any more info on this until mid 2017

    There’s a lot of skepticism towards this company and their ambitions – I hope they prove those skeptics wrong. There’s a lot riding on it, for all of us.

      Tesla is illustrating to the world what can be done with EV and to a certain extent they have already achieved their goal. That is, decarbonise transportation. They have already shaken up the world’s vehicle manufacturers and shoved them down the path of the EV. . The question is, have they gone far enough down this path to create an unstoppable EV revolution? Hopefully the Germans and Chinese will take up the challenge and progress the EV transformation. If the die is cast, and the Rubicon crossed, then it matters not if Tesla fails or succeeds in their own business venture.
