I've pointed out to Chargepoint that I do not see low kW charging after the pause at home, and I have pointed out that re-initializing a Chargepoint session gets immediately back to the good 3kW rate. It is coming out of the pause where the charging seems to get stuck at 1.1kW. Below is Chargepoint's latest response, where she recommends that I get Mitsubishi to fix the problem of low charging rate. She also recommends I try a different brand of charger (besides home) to see if the 1.1kW rate also happens there. But I'm having a hard time psyching up for paying 3 cents per minute, where 12 miles worth of charging would cost $1.80. Since the drop does not always happen, it might end up being a $25 experiment, and I'm not even sure EVGo provides graphs. Does anyone know of a contact at the Renault–Nissan–Mitsubishi Alliance that could help with this apparent 'lack of proper handshake after pause' problem?

Thanks for all that info - the amount of detail was amazing!
After further troubleshooting the stations you used, we found that none of the other vehicles who have used those stations have experienced the same issue. I also consulted with one of my colleagues, and we think it may be the vehicle's battery management system that is causing this whereas the vehicle's BMS drops the voltage down extremely low, to where it finds a steady sine wave, or is comfortable, and then has difficulties building back up.
If it's not too much of a bother, I would encourage you to try out another manufacturer's stations to see if you receive the same results. If you do receive the same results, it's definitely the vehicle's BMS, and Mitsubishi should be able to offer further guidance on possible solutions.
