    Thanks, Rick, got it now. I guess I'm always thinking an amp is a lot of power around the house - my entire stereo system with all knobs to the right doesn't pull an amp. I don't have any intuitive feel for electricity. Or enough hair to need a dryer.

    A little digging. A 1500 kW hair dryer is one of the most powerful (or power-hungry) appliances in the average house, about the same as a electric lawn mower!

    User 15004212: ISTM that the implications are straight-forward and much as you suggest - they would need more power per event - either by longer duration or greater discharge/charge currents or both.

    IIRC, the further they allow the frequency to move from the target, the more power it takes to bring it back in. At least in part because all the devices using the off-target power are running less and less efficiently the further from the target the frequency gets and hence they need and demand more and more power just to get the same work done.

    It may be that Hawaii simply can't do any better at this time. And they don't have a friendly neighborhood grid they can call on to help out, as PJM does, e.g.

    IIUC, this is exactly why the power utilities pay a premium for faster response times: they are willing to pay more per kW because they need a lot less kW if they're delivered in a timely manner.

    1500 watt hair dryer? That's more than my microwave. Amazing. That's serious drying power!

    Still doesn't get to 145 amps; 4.5 x 12 = 54 amps. CLoser than I figured, though.

    :)

    I figured some Brit would correct me.

    If you're just standing around, here's a very readable article on queuing (yes, from the Brits):

    No, it's not, D-inv; your premise is wrong: But you're free to keep thinking whatever you want.

    I'm a born and bred American - we queue orderly and happily like no others, IIRC.

    I got that math, geopark, it was the 4.5 hair dryers. The two paragraphs I excerpted occurred in series in the article and it seemed they were drawing an equivalency. Surely 4.5 120V AC hair dryers are not drawing the equivalent of 145 amps at 48V DC. I mean I surely don't get that. My townhouse doesn't draw that much current! Then again, I'm a chemist.

    John, I may have asked before, and if so I apologize, but is any temperature-related battery-related data being collected? If so, can you share? Do the boxes get hot? Do the boxes have vents or forced air? Any anecdotal information you can share? Have you ever heard anything from the drivers, maybe about their opening the boxes to see if they were hot?

    Given that the ePower app is not using the batteries at the lowest range of their internal resistance, I am encouraged that thermal issues haven't emerged.

    Hold on a sec:

    "Indeed, Audi says that the peak current to the electric turbo in the A6 and RS5 prototypes it demonstrated to the press is 7 kilowatts, about the equivalent of 4.5 hair dryers."

    "The 48-volt system used by Audi lowers the amperage needed to provide that to a manageable 145 amps, something that would be impossible using a conventional 12-volt system, which would need 583 amps."

    4.5 hair dryers = 145 amps at 48V?

    Please help me understand this!

    Actually, I would like to speak with them if they aren't requiring five-figure checks. No call yet, though.
