Actually on topic:
I had my first opportunity to DCFC after 19 months of driving the Bolt, first two DCFC and First opportunity to be an EA customer, my observations and the feedback I sent EA is pasted below
1) Ice in charge connectors:
or "trying to DCFC during the "Polar Vortex" We have had some bitter cold temps with freezing rain and significant snow accumulation recently. When I first attempted to connect to a charger I could not seat the connector. Upon close inspection I discovered that the connector was partially filled with ice, preventing it from being inserted all the way. I visually inspected the connectors on the other chargers and found one that was clear of ice. I observed that all the connectors are stored facing up and the holders do not sufficiently cover or shroud the exposed charge head from driving rain or snow. It seems that the best solution is a rubber dust and snow cap that can be tethered to the end of the charge cable and put back into the plug after charging. Alternately, a full receptacle that you can plug the charge head into on the charge station that would fully protect the plug.
2) The screen glare and display angle:
The display screen is low and angled up. Even in overcast conditions I found it barely readable. Mostly I saw my reflection in the screen and I needed to use my hands to shadow parts of the screen at a time to try to read the display. I can’t imagine trying to read the screen if the sun was out.
3) Abrupt charging end at 87%:
The first charge I actually desired a near full charge, as with the cold weather and reduced efficiency I desired a safety buffer of charge. During the charge taper the charger abruptly terminated @ 87% and the charger appeared to reboot. I assume that some power level negotiation with the Chevy Bolt failed and it simply terminated, but I am not sure what actually happened. I noticed another comment on PlugShare for this location that noted the same thing.
4) Card reader / reboot:
My first charge required a call to support and a station reboot. When I got to payment on my first attempt the screen said "insert card", but the card reader face displayed "cash only" Reading here and on Plugshare it appears that this is very common. I suggest stations where this issue exists, putting them on a reboot schedule. If you have 4 stations reboot each of them, that is not currently in use, each day between 2 - 4 AM. You would implement a rolling reboot, station 1 reboots at 2AM, station 2 at 3AM, etc… On the return trip I used the same charger and I did not need to contact customer service for a reboot.
Ok, that's it, having used DCFC twice now I hereby graduate from NEWB directly to "Subject Matter Expert" , ask anything you want and I am sure someone with more personal experience,
, will be able to answer your questions ;-)
P.S. having read this thread I was fully expecting the station reboot to be able to charge, customer support was actually great and although it may have felt like 1/2 hour, standing in the freezing cold, with 12% SOC, and very limited Level 2 as my "plan B", my phone call timer shows the call lasted for 7 min 40 seconds, and she stayed on until it was fully rebooted and successfully charging...
