    I still haven't received the replacement for my defective EVSE and even after charging 12 hours with the factory charger, my SoC was only 55% this morning. So, I decided to use the only local DC fast charger, a 50kw EVgo unit, 2.5 miles from my house... i charged up from 55% to 75%.. The fastest speed I got was 39kwh.. That's very slow. At least in the beginning at 55% SoC, I would expect 48 to 49kwh.. The free Greenlots 50kwh charger in Largo, FL gets me 48 to 49kw speed until I reach a higher SoC.. Advertising those EVgo chargers as 50kwh is false advertising as they don't provide 50kwh.. not even close.
    Electrify America gets me close to 50 kwh too on their 50kwh chargers.. It's just EVgo whose 50 kwh chargers don't perform close to their rating. At 35 cents per minute, they should be faster.

    I’ve been very frustrated with EA. It seems most of the chargers around here (Rockford, Illinois, Tomah, Wisconsin, Williamsburg, Iowa) do not work all that well. My most recent attempt to charge at one of their stations messed up my Bolt too.

    I did have issues with the EA 350kw chargers with my Kona. Could not get them to work. EA reduced their power to 50kw to make them work with most cars. What issue did the EA charger cause?

    At first the Bolt turned on a light on the dash and OnStar reported seeing P3022 and P300B codes. The 3022 and light went away by the next morning but the 300B is still there. The vehicle charges normally as far as I can tell but I’m still having my local dealer check it out to see if they can clear that last error code and make sure my vehicle isn’t damaged by the EA chargers.

    Would be interesting to know what those codes mean... Hopefully not a big deal.

    The EvGo 50kW chargers I used between Las Vegas and Los Angeles were doing fine and I got 49kW delivered.
    The only reason I can think of is that maybe the car was drawing less since you just went down the street to charge, so it wasn't properly warmed up like it is when you stop on a road trip?

    I'm in Florida and Temperatures in summer rarely drop below 80F, 26C.. That's not the problem. The problem is that the charger is only rated 100 AMP.. I'm not the only one complaining about those chargers. Check the comments on Plugshare for the Lakeland, Florida and Bartow, Florida. Nobody gets over 40 kwh on those chargers. Like I said, the Greenlots Charger in Largo, FL (Largo Performing Arts Center) draws consistently 48 to 49 kwh below 70% SoC. Same goes for the Electrify America 50kw chargers. The EVgo chargers between Las Vegas and LA are different type chargers. In baker, they also have 2 100kw units (OLLIE and CHANCE) as also a 350kw unit (JANUS) as also a 175kw unit (IVO). Only ASTRID and NISKA are 50kw units and they are different 50kw units than we have here in Florida

    I see, that sucks. Weird to put in a 50kW charger with only 100 amp.

    Most EVgo units in Florida are only 100 amp.. I believe that the one in St. Augustine was 125 amps..
    My issue isn't really the charging speed itself but the billing. They are billing by minute and not by kwh..
    I paid $8.40 for 14.54 kwh of charge. That's almost 60 cents per kwh..
    In Baker, NV, you can charge on the 100kw unit for 27 cents per minute and it will charge twice of the speed that my local EVGo unit will charge at for 8 cents less per minute. This ain't right..

    Charge costs billed by kWh is a better way to go. In Nanaimo (right now) the only DCFC that costs money to charge is based @ .35/kWh, basically 3 times the cost of home charging. :

    Problem here is there are so many apps required to access all the machines- or in my case RFID cards (no phone), Why can't they just enable credit or debit payment? Should be required by law:mad:

    I have apps for ElectrifyAmerica, EVgo, Chargepoint, Greenlots and Semacharge already.. Most units do accept credit cards here but the credit card reader on the local chargers hasn't worked for over a year according to comments on plugshare.. However, works fine with the app.. It did not read my RFID card for EVgo either.. I got RFID cards for Greenlots, Chargepoint and EVgo.

    Sounds pretty simple - fix the readers.
    It took almost 2 months for B.C. Hydro/Greenlots to fix my RFID reading errors, and that's for just one network! :confused:

    Charging by kWh apparently 30 states allow billing by kWh now. Just wondering why they don't start implementing it.

    That seem to be a common issue with those charging stations.. RFID often does not work.. Of course, most of the chargers are exposed to the elements and I can see where issues will eventually happen, especially in areas with lots of rain.

    Because they would make less money. People would start charging past 80% when charging speed slows down to 25kwh...

    As far as I understand and have been using fast chargers, the charger knows the SOC of the car. It SHOULD be easy enough to program the charger to stop charging at 80% and then charge idle fees. Or raise the price at 80%.
    It's not like we live in the middle ages where there needs to be a person standing next to it, or in Oregon for that matter.

    (Oregon does not allow you to fuel your own ice car!)

    Of course, the charger knows the SoC of the car but each car adjustst charging speeds differently. Pricing would become more conplicated if there was a different rate based on SoC. The charger can't just shut off at 80% if the user wants to charge to a higher SoC..

    I second the price increase above 80% , many L2 locations if needed, idle fees should remain the same after a set period of no charging activity.

    I agree on the various charging speeds, so there must be a set max time 45 min should do it before additional fees are implemented (or a re-start -providing no one else is in line). Easily attained by a button on the machine (no app required)

    I'm very much in favor of idle fees. Around here, we don't have lines at charging stations and it's usually fairly easy to find an available level 3 charger. However, as EV's become more popular, it becomes very important for people to move their cars once they are done and therefore, I'm very much in favor of those idle fees!
    The only problem I see with changing the rate after 80% is that every EV is different when it comes to charge management and some cars drop the charge rate much earlier than others. In case of the Kona, there is a significant drop somewhere around 75% I believe.
