Re: ChargePoint Charging Question

Another possibility is that the Chargepoint pilot signal had already "given up on" the car that was plugged into the other line (and done charging), and the software's logic then would have no reason to also reduce the MiEV's charging (by changing its pilot signal too). Recall that my theo...

Re: ChargePoint Charging Question

Thanks for that experiment. But kind of disappointing that the bug of slow charging did not show up. I don't think I've ever seen my car jump right back to full draw (3kW) right after a pause when it is on a dual cord Chargepoint station. I either have to call in for a reboot (which is not allowed a...

Re: ChargePoint Charging Question

On my MiEV, I am finding that if I take it down to about 18 miles left (about 30% SOC), it is anybody's guess if it will pause or not. If it does pause, it will likely do it within minutes of plugging in. If I take it down to about 10 miles (likely 15% SOC), it will pause for sure, but maybe about a...

Re: ChargePoint Charging Question

I look forward to finding out what the pilot signal does during a pause. I appreciate that help. To close out an older question on that Clipper Creek recall or not: I called a Mitsubishi dealer (service department) and the guy looked the car up using the last 8 digits of the VIN. No recalls showed a...

Re: ChargePoint Charging Question

Below is the relatively quick response I got from submitting Monday's discovery that the "post pause" rate went back to 3kW when the other cord became available. I plan to hit them up in another week or two to check on status. Given that this has been a reported problem since January, I do...

Re: ChargePoint Charging Question

I do not know any Chargepoint station model numbers, but on all four dual cord Chargepoint stations that I have tried, all four very dependably change to just 1.1kW after the pause. The single cord Chargepoint stations dependably return directly to 3kW.

Re: ChargePoint Charging Question

Today a drove a little extra, to discharge the battery enough where for sure it would pause during charging, and I plugged in at a dual cord Chargepoint station. I had planned to plug in my other car once the MiEV had paused and dropped to 1.1kW, but it turns out the other cord was put in use before...

Re: ChargePoint Charging Question

Thanks to Joe S's digging into details, and the new theory that a neighboring car unplugging from a shared station might cause a MiEV charging to move from the funky 1.1 kW "post pause" rate back to 3 kW, it occurs to me that I might be able to replicate that in a controlled fashion. I hav...

Re: ChargePoint Charging Question

Looking back at that, I would say that it is very likely that the other car unplugging might have caused the station to adjust (and refresh) pilot signals, and that is what likely caused the charge going back to 3kW. Too bad that station has such low usage, otherwise others plugging out could often ...

Re: ChargePoint Charging Question

Below is the part from that Wikipedia link that indicates to me that the pilot signal from the station indicates to the car how much current can be drawn: "Control Pilot (Current limit): The charging station can use the wave signal to describe the maximum current that is available via the charg...
