Sounds like your rate was higher than the station displayed. You need Bolt Spy. FYI; I am using my EVGO credit and I am only getting 32-33 cents/kwh during peak @ 25 cents per minute. As far as the cold pack charging; I don't understand that at all.
I did a side by side at EA with Bolt on a morning where Bolt drove 30 miles to the station and I drove 3.4 miles and yeah my car was garaged but hadn't been charged in 3 days so my batt temps were in the mid 40's. (its garaged at night but spends over 12 hours a day outside on work days.)
Well, he started at 22 KW, I started at 71 KW. He finally hit 40 KW after 15 minutes and 45 KW but only for about 15 minutes before the ramp down due to SOC (I guess) happened.
What the charger displayed was probably accurate for me. I almost never DC FC and this was my 1st time on a paid one and one that charged by time, at that. There is no Bolt Spy. Closest is Torque Pro with the necessary OBD2 dongle. When I have some time, I'll look into it.

came out on March 2, 2020 so I obviously don't have it. I've only had time to look at a few comparisons and it apparently doesn't help that much and also doesn't alter the pre-2020 behavior of having these sharp drops at particular % SoCs. 2020 Bolts apparently have a more gradual drop at each % SoC mark.
I'll probably get the above update done in the near future, but I doubt it'll help me much.
Lesson learned for me is not to use a charge-by-time DC FC when my battery's cold. There are several 25 cent/kWh DCFCs (62.5 kW) at ChargePoint HQ and I have hit 54 or 55 kW on them before when they were free. But, my battery was warmer then. They're not near home and it's not worth my while to make a trip out there unless I'm going to be in the area. I did use them recently (paying $) when I was in they area.
I did submit my experience/feedback on Plugshare about the EA location, including a request for per kWh billing instead of by time.
Because I need to WFH for who knows how long (months?), WFH + some home EV charging will push me into tier 2. Currently, my off-peak (cheapest) PG&E rates in tier 2 are 29.222 cents/kWh. Partial-peak (rest of day) are 30.905 cents/kWh.
Once we hit "summer" (begins May 1), my tier 2 rates for peak, partial-peak, and off-peak per kWh are 48.1, 36.3 and 28.8 cents/kWh. This comes from page 2 of https://www.pge.com/tariffs/assets/pdf/ ... DS_E-6.pdf
. They update those rates every few months.
Prior to my county (and now state) lockdown, almost all of my EV juice came from free L2 charging at work.
Another annoying part about EA is this (from https://www.electrifyamerica.com/faqs
How do I change from one membership type to another?
In your account, go to Plan details and follow the prompts to change plan types. Please note that a request to change from Pass+ to Pass membership will only go into effect on the 1st day of the next billing cycle, which coincides with the monthly anniversary of your sign-up date.
So, I was in a sense forced to choose Pass+ from the beginning. If I chose Pass (no monthly fee) then if I wanted to switch to Pass+, I'd have to wait up to a month for it to take effect.
