  • The “92% efficiency” figure quoted by Tesla isn't as good as it sounds, but it doesn't matter. The PowerWall batteries themselves likely run at.

    Battery degradation is one of the biggest concerns for electric car owners and potential buyers, but data from Tesla battery packs have been.

    Compact, affordable and simple to install, Powerwall 2 charges during the Usable Capacity kWh; Depth of Discharge %; Efficiency 90% round-trip .

    If you need miles on a single charge, a XD does that quite easily, even in winter. Sorry to the readers for the error and thanks for finding that. UC San Diego installed this system, which has 5 megawatt-hour MWh capacity—enough to power 2, homes—in September Retrieved May 21, The company's smaller battery designed for daily cycling is all that remains.

    Special post by Bruce Lin and Matthew Klippenstein. As energy systems developers with experience in several different chemistries and system scales, we can make some well-grounded educated guesses on the design and economics.

    This is to match the DC input of typical inverters. Amortizing the capital cost of your system, by ensuring long lifetime for the batteries, is far more important. The battery architecture is designed for long durations, which means low power.

    Each module has 6 groups, and 74 cells in parallel per group. This makes a total of almost cells, with an operating voltage of about 48 VDC which makes certain safety aspects easier to design. The two packs are one-eighth of a Tesla Model S 85 kWh. Our Catalytic battery model suggests this is as low as 0. The tradeoff is that they are putting in many, many cells to supply the 10 kWh — far more than would be necessary for the rated 2 kW of power, or even the peak 3.

    In a car, those two modules would be pushed to deliver about 30 kW of power In other words, the PowerWall was designed for energy output, not power output. By the way, this is the traditional argument of flow battery proponents — if you want to store lots of energy in regular batteries, you wind up being massively oversized for your desired power output; the faster you discharge electrons, the bigger your losses become, and the bigger energy your battery has to become, to deliver the same kWh to the outside world.

    Alternately, if you did want to run high power, you would need more cells to supply the 5 hours of energy. Customers will just need to be aware that they will need multiple units to serve high power.

    Another benefit of operating at such low current densities is that there will hardly be any waste heat during charge and discharge as a result of the lower resistive losses. However, ambient temperatures will be the major thermal issue — cooling during hot days to ensure long lifetime, and heating to prevent the cells from freezing in the winter.

    The Model S pack already uses liquid cooling, so why not use the same technology? The 10 kWh unit is only rated for weekly cycling, which means far fewer cycles over its lifetime about rather than roughly 3, By comparison, the , mile warranty on the batteries in the 60 and 85 kWh Model S implies up to 1, deep-ish discharges, or a much higher number of much shallower discharge cycles.

    Elon Musk noted in the Q1 earnings call that it does not make economic sense to go off-grid, with PowerWalls.

    The PowerWall sale price is an excellent real-world confirmation that manufacturing prices really are in this range. Musk was being slightly misleading in his Q1 earnings call when he said the inverter is part of a solar installation and should not be counted in the cost.
