EV System Fault and Charging Error

My MY24 suddenly popped up today with the message "ev system fault detected" shortly after startup. It indicated it was safe to continue driving, so after a short errand, when I got home, I plugged it in to my L2 charger. I then got the red light at the charging port, "ERROR" on the display and "Charging Fault" in the app. System status app in the car shows no messages. Retried with my wife's charger (different brand) with same result. I can't find anything specific to this message in the forums or online relating to the I-Pace. The car is up to date on software loads and is ~1000 miles out from the first service (which I've been getting a message about for a few weeks).
Any idea what's going on?

It definitely says "EV" and nothing about charge limits. Online I have only found descriptions of this for Range Rovers: EV System Fault Detected | Range Rovers Forum -- the first dashboard picture is exactly what I'm seeing. This seems to indicate it has something to do with the battery coolant/cooling system. One poster in the thread said he had "filled up the coolant" -- is that even something that can be done on the I-Pace?

iGuide's guidance is "Contact a retailer/authorized repairer as soon as possible." Not helpful for know what the problem is. One needs to retrieve fault code(s) as soon as possible after the fault is displayed. Anything is speculation unless fault codes are retrieved.

Yes one can fill up coolant. You should have received a message for low coolant if that was the problem.

So if a fault code shows up in the instrument panel, how long is it stored for a technician to pull the causes of the fault code? What happens in my case a fault will appear(ok to drive brake pedal feel reduced) and then will disappear for days or weeks until it shows up again. Pretty sure not the auxiliary battery since it is being monitored. Does the code need to to be present for a technician to diagnose?

I determined where the coolant was and checked it; it is fine. I've let it sit for a few hours and just plugged it back in. I'm not getting the red error light now, but while the charger indicates it is connected and offering charge, the car (in the app) says it is not connected. Not certain if that is better or worse.
And of course these things happen on the long holiday weekend...

I left if plugged in for several hours, but it didn't do anything. When I unlocked the car, it started to charge briefly and then went red. Sounded like the cooling fan began to spin up, and then it stopped charging with the error message. Since the coolant is ok (At least level-wise), that's not sounding too good.
Definitely reproducible, unfortunately. Hopefully remains drivable, at least.

Where are you located ? I had several problems with the granny charger due to how the home wiring is arranged in the Netherlands. We have a 'central box' system. Meaning : a central ceiling box ( mostly a light fixture ) is wired directly from the fuse box. Then sockets are wired from that point. With the newish installation with 'clip' connectors this gives a contact point of a very small surface. With several of these connections in series, and high amps resulting in contact erosion / resistance : the charger adds these up but interpreted it as a single resistance prone to a fire hazard: the carger refuses to function. I suggest to hook the granny charger up to an outlet near the fuse box, better one coming directly of the fuse box. Give it a try.

Just got her back; issue was the high voltage heater. Due to where it was located, they had to remove the traction battery. The codes on the service form were:
P0AA6-00 logged in the BECM
B1DC5-93 logged in the HVAC
Hopefully just an anomalous issue and we're good to go from here.
