Charging suddenly stops on DC charger

  1. You can adjust the DC (and AC) max charging level in the settings to a level lower than your SOC and stop the charge without having to lift the hood or use the stop button on the charger .
    Hopefully the design of the HV contactor is constructed in an arc resistant manner.

    I checked, and don't see where the Kona can limit the DC *rate* ... just the
    desired SOC. For current adjustment, the OM says "for level 1 and level
    2". DCFC appears to place us *entirely* at the mercy of the EVSE and
    whatever mood the car's BMS is in that day.

  4. Why would you ever want/need to adjust the charging rate? What's wrong with the car and charger negotiating a rate based on current variables?

    ElectrifyAmerica bumps you up to a new price tier if you go above 75kW. That would be one reason to throttle it down a little bit.
     
  6. That's a weird pricing strategy, isn't it? Isn't the whole point of fast charging to go fast? Shouldn't they charge for the amount of power you pull rather than the rate at which you pull it? Imagine Esso saying we've got new, faster pumps but the gas in those ones costs 30% more! Use the hand pump out back and the gas is free!? Like I said: weird.

  8. Yes I agree it is unfair particularly seeing as Kona will only hit that second tier briefly yet have to pay more for the whole session.

    Almost precisely that. I was reading a bunch of horror stories about EA and their
    flawed/buggy pricing tiers. As many others have pointed out here and on
    other media -- kilowatt-hours are the "gas in your tank", not time, and other
    than minor idle fees, that's clearly what everyone should be paying for.
    Penalizing drivers just for having a narrow "filler pipe" is just wrong, it's
    not under their control. Taking a long lunch after their charge finishes is.

    Overviewing all of this is part of my shopping process, deciding which
    networks to sign up with. I in fact just bitched EA out pretty hard about
    the pricing tiers this evening, and the rep took it all pretty seriously and
    agreed that there were unfair circumstances with some vehicles and
    they need to handle it better.

    Not bad, considering that it's effectively a directive to uproot their
    whole business model. But it's sadly needed. In the meantime,
    being able to control which pricing level one is buying into would help.
