Sorry, maybe I misunderstood you. I didn't realize you were talking about home charging. I thought you were suggesting that electrical infrastructure to support 60kW charging wasn't common. I was saying "Sure it is, it's right there in many recent high-end housing developments." Of course a homeowner won't want to shut down the pool heater and aircon to charge the EV. So if you're talking about home charging, that would require a second service drop dedicated to the EV. The cost would be astronomical, not just for the electrical service, but for the charger. I can't imagine it would ever fly as a mass market product. It'd be a custom built deal for the likes of Elon Musk and Neil Young, 0.1-percenter-and-EV-fan types. If the EV were smart enough to reconfigure its drive inverter as a charger, it could bypass a lot of the charger expense. IIRC, at least some of the AC Propulsion EVs did that. So, apologies if I didn't get your original point. PS - Lee is right. I didn't consider the fact that the power companies design for residential continuous load at a tiny fraction of peak load. I was thinking too narrowly. I expect one person in such a development, maybe two, could charge EVs at 60kW. I don't know how many more, but at some point protective gear somewhere would say "whoa, no more," making a lot of electrical customers unhappy. Thanks to both of you for catching my errors.
