Re: Weird Charging Curve

Hi all, I went checked my car at the dealership and no error code was found on my car. Now it is becoming more difficult to pinpoint the problem of charging not able to restore to level 2 at 240 V after time out dropping. I am lucky, the technician I met did not stop in telling me the car is fine. I...

Re: Weird Charging Curve

Sorry there is a typo. The total elapse of time is 4 hours 30 minutes.; not 2 hours 30 minutes. It really talke a long time to charge.

Re: Weird Charging Curve

JoeS, I checked into the owner's manual for "Regular Charging is discontinued" and there are 5 possible causes listed. The one that, I think, most reasonable for my case is "The temperature of the main drive lithium ion battery is too high or too cold to charge". Well, I think yo...

Re: Weird Charging Curve

Wow, I do not not even know that much detail about stopping of the charge. Thank you for sharing. I thought the stop was due to too high or low a temperature in the battery or on-board charger. I will certainly ask the technician of the dealership if this is the way the on-board charger is programme...

Re: Weird Charging Curve

Yours look like the typical charging curve of mine with the old Chargepoint EVSE before the station owner changed to the new ones. The old curve shows a notch or two and then recovers to full charging power. It eventually tapers down as battery is nearly full. With the new ones as you can see, it sh...

Re: Weird Charging Curve

Thank you very much for your thoughts. I am aware of the final tapering down curve when the battery is nearly full. What puzzles me is that after the dip, the full charging power could not be recovered while the battery is still far from being full. It means I have to wait much longer to have a full...

Weird Charging Curve

Hi, I have a 2012 es imiev with mileage of 55324. I used to charge at a Chargepoint Level 2 station with a single output. The normal charging curve shows currents drops to almost zero at least one time, then it would get back to full about 3KW (actually less than that) after about 10-15 minutes. Thi...

Re: Clipper Creek EVSE

derminghsieh, perhaps you're being a little harsh on Mitsu at this point in time, especially since it looks like they're working the problem. I haven't received such a notice from Mitsubishi (yet?) and I hope they're addressing the apparent incompatibility between the Remote and non-Mitsu EVSEs (an...

Clipper Creek EVSE

I just got a letter from Mitsubishi with "Important Notice Enclosed". And it made me really angry. In this letter, Mitsubishi is apologizing to the users of Clipper Creek EVSE and working out a software solution that is going to be implemented starting from January, 2013. Why is Cipper Cre...
