Did you happen to take note who the manufacturer of this charging station was at BoA? Normally the name is on a metal plate mounted to the side of the tower, listing other specs (part numbers, amperage output, etc). I'd be curious to know and confirm that it was a SIGNET charger since that is the troublesome one for the XC40 (and Polestar 2).
@arijaycomet - I appreciate you're posts. Please don't hold back on sharing useful information.
FWIW, I test charged a demo P8 at a Signet charger - EA had told me ahead of time that it was Signet charger and wouldn't work, but it charged fine - at least for the five minutes I was there. 87kw at 50% SoC.
Ok -- so here goes -- So like Jon's post above, I called EA when I tried to charge after 2x attempts to not get it working. Based on some heavy reading and research I've done here and elsewhere, the most tried-and-true success rate for people has been the 150kW units for whatever reason. I don't have a direct contact to anyone at EA that is upper tier support but having owned a Porsche Taycan, and Audi eTron SUV, and now the XC40 -- I've had thousands of miles of driving that includes about a dozen different EA stations. (and chatting w/other owners).
First off -- I had to LOL at what the EA lady on the phone said -- she said that most of the support staff are aware of the Polestar 2 issue and that their boiler plate response is to "go find an alternate charger" -- or to put it another way, they know there is a problem, they have ZERO timeline for a fix/resolve, and can offer no help. She said that nothing was in their database for the XC40, but when I explained that our 78kWh dual motor platform was the same underpinnings, she said it would likely follow suit. That said, the deeper dive here is that for whatever reason, there are 2 "fixes" that sometimes seem to help.
Her first suggestion was that she reboot the system, but her second suggestion that sometimes, for odd reasons, works -- is to activate the charge session from the app instead of RFID card / credit card. I could not get the latter started/working -- but after a reboot to a 150kW terminal, and my XC40 at around 50% SOC -- we did successfully get a session going. Activation occurred with my Apple Watch as the RFID signal sender (NFC? whatever you call it). It peaked at around 100 kW which based on the SOC made sense, and after adding about 20% energy into the car we were ready to leave.
Again there is ZERO guidance here from the tech support team, and ZERO knowledge as to when this will be shared. However, in talking to a local friend here in Cleveland, Ohio, that has a Polestar 2 -- his feedback was that the most recent PS2 update has done wonders to fix these problems. But it seems that we XC40 owners are "one step behind" with the PS2 updates, such as phone-as-key feature isn't unlocked for us, etc. So does this mean that the Volvo fix for the charging is coming? Hard to say--
My suggestion(s) moving forward then are---
1- start at a 150kW station
2- if it doesn't work, call support, ask them to reboot the system
3- wait for the time (top right corner) of the EA station to sync/be correct
4- start a session there after on said 150kW (not 350kW) station, and hope it works!
For the record, this was the Mansfield, Ohio EA station (Walmart 5471 - Mansfield, OH - 2485 Possum Run Rd Mansfield, OH 44903) that this occurred.
