  • Mar 22, While Panasonic, Tesla's battery cell manufacturers, lists the A Youtube channel bought cells from eBay, where the seller claims that It sells vehicles under its 'Tesla Motors' division and stationary battery pack for.

    Aug 6, The most popular battery pack supplied by Tesla contains 7, cells in 16 cell modules capable of storing up to 85 kWh of energy.

    In contrast to every other automaker, which use specialized large format Li-Ion cells, Tesla's battery pack is made up of thousands of inexpensive commodity cells similar to those found in laptops. In this case, the company's cell design eliminates the relatively complicated battery cap of the commercial cell, and replaces it with a simple aluminum disk.

    He said he had "no interest in an article that debates what we consider to be an obvious point -- which is that there is a dramatic reduction in battery costs," then went on to tell the reporter, "You clearly do not understand the business," before apologizing and ending the interview. The resulting Barron's story argued that Tesla's stock price was overvalued, because the lithium-ion cells used to power Tesla's vehicles cost a great deal.

    The figure is widely cited by journalists who write about Tesla-- The New York Times last year, for instance. To test that notion, I contacted one wholesaler and offered to purchase a small number of the '' lithium-ion cells Tesla uses in its packs. Considering the small number of cells, and the free offer of attached or unattached, my choice circuit boards, it seems clear Tesla's price in great volume could be much lower.

    In contrast to every other automaker, which use specialized large format Li-Ion cells, Tesla's battery pack is made up of thousands of inexpensive commodity cells similar to those found in laptops. Unlike automotive cells, these cells are produced in the billions, subject to the fierce competitive pressures that are a signature characteristic of the computer and consumer electronics industries.

    Even including the overhead of the pack enclosure, connections between cells in modules and modules in the pack , sensors, and circuitry, Tesla likely has lower pack costs than any other maker of plug-in electric cars.

    When used as a laptop battery, each cells requires a safety mechanisms to prevent fires. But in a large, electronically-controlled, liquid-cooled battery pack like the one used in the Tesla Model S, having certain safety features on each cell would be redundant.

    In this case, the company's cell design eliminates the relatively complicated battery cap of the commercial cell, and replaces it with a simple aluminum disk. Having radically simplified the cells, Tesla then designed simple and inexpensive fireproofing systems into its battery pack.

    Among many innovations, Tesla appears to have incorporated a form of intumescent goo that it sprays onto the interior of the pack to aid in fireproofing. When exposed to heat, a chemical reaction occurs in the goo that helps cool the heat source, while simultaneously forming a fireproof barrier to protect the rest of the pack.

    In testing by Tesla , this material often cooled cells experiencing a runaway reaction--to the point that many failed to ignite at all--and provided a fireproof barrier surrounding those that ignited. The potential safety advantages of Tesla's small-cell approach were highlighted during the Boeing Dreamliner battery-fire fracas.

    As Elon Musk pointed out , it can be quite difficult to cool large-format cells efficiently, and even harder to contain them once they do ignite. Thus far, Tesla has never experienced a battery fire in a production pack. Panasonic is an investor in Tesla Motors , so there could be an incentive to work hard on lowering the price for specially-developed cells to a company it partially owns. Yet that's the price that prestigious consulting firm McKinsey suggests will be reached in by the industry at large.
