Considering the XC90 Recharge but the recharge time of 5 hours - is a really big negative - in doing further research the Volvo website says with two phase charging the total charge time is 3 hours. Does anyone use two phase charging in the U.S.?

    I am always saddened by the fact the United States is locked into a sub-optimal grid topology. Providing three phase 400V power to all customers results in so much more reliable a system. Just can’t see a credible way from where we are today to worldwide best practices though.

    Maybe 3 phase 208 should be the goal. That would be a hard transition but at least all the 120 volt devices would keep working and we wouldn’t need to change outlets.

      3 phase 208 is very common in commercial buildings and apartment buildings in the US. We just only deliver two of those phases to a single apartment giving effectively single phase 208v power.

      Lots of public L2 chargers are actually 208V instead of 240V because of this. For example a 6.6kW L2 charger is likely 208V / 32A.

      How does the lack of an additional phase mean anything for reliability? The 240V system is just fine.

      I am not sure I understand? Most of the transmission lines I see are three phase. It is only at the residential distribution level that we see single phase. Most commercial sites are three phase and as noted most DC fast chargers are three phase. I don’t see anything sub optimal about that.

      What a ridiculous hot take. I suggest doing a bit more research on the grid before getting sad about non-problems.
