Tesla Power Wall is just a fancy enclosure with a small part of a Tesla pack so it could be part of the solution that Lee sketched. It is called power wall but it does nothing until you add a charger and an inverter to actually get energy in and out of the Power Wall. I have stacks of cells in my garage, if I wire those together I too have a power wall, minus the fancy enclosure. In fact, I have many times more energy than a power wall. As you can tell, while I love what Tesla does, the power wall is a bit overhyped in my opinion because it is just a box with batteries and BMS. Buy a used Leaf pack and you have the equivalent of 2 power walls. I have two Leaf packs sitting in my garage...

The same guy that wants and can afford a top-of-the-line luxury EV is going to want a top-of-the-line luxury fast charger. If he's in the USA, he won't have 3-phase power in his home. But he *will* have 240v 200a single-phase service. That's 48kw if you dedicate it all to the charger. So, someone is bound to offer such a charger. To make it actually work, it will have to sense the home's present power usage, and "throttle" the charger to use whatever is available. If the home's other luxury toys are using 100a, then the charger can draw 100a without tripping the 200a main breaker. Naturally, they will advertise that it "charges at *up to* 48kw to recharge your Tesla in *as little as* 15 minutes!" (asterisk...) The asterisk points to tiny text that no one reads, which says "...if nothing else is turned on in the house, and the Tesla isn't fully discharged". Personally, if I were doing this... I'd make it a whole-house UPS with its own bank of batteries. These batteries are charged slowly, during off-peak hours. If you need a fast charge, they are "dumped" into the EV. Or, if the AC power to your home goes off, they can provide backup power until it comes back on. -- A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away. -- Antoine de Saint Exupery -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
