Charging not possible. First time I’m ever charging.

[Phix9000]

2021 taycan base, I’ve owned the car for about 2 weeks now and plugged into my at home charger for the first time. (The $1200 optional charger) according my my window sticker. Plugged the charger into the wall and car and it said “charging” with green blinking light. I come out 30 mins later and it’s blinking white and says “charging not possible”

Now I can’t figure out how to get it to work again? I’ve never had an EV and I tried both sides of the cars charging ports as well as 2 different outlets in my garage.

I wonder if you can share more info as what you are saying does not have enough detail to help you.

- What kind of home charger do you have? Brand, rating, directly wired, or plugged into outlet, is the outlet specifically installed to be used for EV charging.
- $1,200 is the external Porsche charger and not the one that is built into the car
- Both ports are compatible with home AC charging

After reading it a few times, it appears that you might be using your household 120V outlets to charge the Taycan. That is not going to work for any practical purposes and highly discouraged.

Pictures would be helpful if you can share.

I’m not even sure what i did exactly but i got it working again for now. I’m using the porsche brand charger. Using the drip charger as I haven’t had the proper socket installed yet for fast charging. Says it will be charged by Friday at 1pm lol

Just did it again I walked back in the garage and it’s blinking white says charging not possible. No clue.

both times it turned off at the 45 min mark exactly

You may want to go to a local shopping center or other locale that has a level 2 charger (relatively slow compared to Electrify America (Level 3)) but would approximate what you are trying to do and see how that goes. If it works OK on BOTH sides of the car (you have two useable sides for Level 2 charging), then your car is OK for Level 2. That would also mean that your Porsche charger or perhaps your outlet is the problem. You are doing this simply for diagnostic purposes.

If you are feeling ambitious also go to a level 3 charger (use the passenger side only for Level 3) to insure your newly acquired vehicle can handle Level 3.

Edit: for Level 2 charging it is possible that your car has "timer" that won't allow charging except during certain hours. Since you are new to this, that can be pretty confusing. For now I suggest you choose the Direct Charging option in the PCM to force all Level 2 charging to be immediate.

Buy a different charging unit. Grizzle E is a great dumb charger and if you want a smart charger charge point is very good. The Porsche charger is horrible and should just be thrown away in my opinion.

This explains it. Your best plan for now is to use a public charger, as what you are doing is about the worst thing you can be doing to your car.

Not enough juice - the equipment you have when properly plumbed in and configured is first rate IMHO (most folk in NA will violently disagree however!).

Urge you to read the manual for this unit and to use the web interface when connected to your home wifi (or hotspot to your mobile) to access all configuration settings. Access codes will be in a white envelope which should have accompanied your EVSE.

Just a guess, but I suspect something is getting hot and the Porsche unit is shutting down. Cools off and you can charge again for 45 minutes. In an emergency I have used a Tesla Mobile Connector to charge at 120 volts for 10 hour stretches with no failures. Not ideal, but charging on a 120 volt circuit is very doable. On a 10 amp breaker you should see just about 1kW charging rate on the car's display. You are showing 0.28 kWh delivered in 30 minutes (barely over 0.5 kW charge rate). That is a charging loss way above the usual 12% to 15% on level 1 (and probably indicative of higher than normal resistance somewhere). Put the Porsche Connector on a shelf and leave it there until you sell the car. There are many excellent EVSEs available, ideally hardwired to your panel. If you road trip get the Tesla Mobile Connector and a Tesla Tap NACS to CCS adapter for the car. Inexpensive, 1/3 the weight and size of the Porsche unit, and bullet proof reliable.

PMCC requires a minimum amp supply - 6A - 32A (UK) so US will be similar. Looks like OP's is just out of the box and not set up so it could be its set for something and not receiving. Unlikely to be overheating if on a basic supply.

I'm at a loss to explain how different the experience with the Porsche units is US vs UK but our units are just not good. A neighbor just had his "pigtail" updated to the ones with heat sensors (not sure if that was a UK recall). Plugged in and charged for 5 minutes until the unit faulted. Let it sit and it would resume charging after maybe 10 minutes and then fault again. Never an issue until the getting the new connector so the assumption is that the new cable with the thermal sensor is faulty and tripping way early. 50 amp circuit and a Hubble socket. You could be correct and it is a setting, but the car is a 2021 so the PMCC has probably been used and configured. Over here, when in doubt blame the Porsche EVSE.

Thanks for all the replies guys. I changed the amps from 6 to 8 with the configuration on the charger. That did the trick. I got about 20 miles of range for that overnight charge. Obv not ideal but I needed a quick top off as I never charged the car yet. I will be looking into the emporia level 2 charger as recommended. I have an electrician that has done a few of these installs in people’s homes by me.

Is the consensus to use public chargers when possible like electrify America over any at home chargers?

Level 2 (home) charging is a little easier on your battery over time. Unless you have free charging at EA home charging will be significantly less expensive. Oh, and EA sucks. De-rated chargers, broken equipment, lines waiting to charge are not at all unusual. I still have free (really prepaid) charging. On a road trip I gladly pay to charge just to avoid EA locations known to be horrendous (FPL, Pilot/Flying J, Buc-ee's are rolling out decent alternatives).

Good plan.

EA is usually a go to given Plug-and-Charge support since you are a 2021 and 3 years free (if still so)
Otherwise, as others said Pilot/GM (EVGo), Mercedes, Circle-K, etc., but prices can be wild.
I had great experience at a Chevy dealer on the way, so there are some diamonds in the rough. You can share your approximate area and we can look up and advise you on what to use via Plug Share.

The car Nav -> Charging tab will show you the chargers, but I filter out anything below 150kW, then save them as Favorites with an indicator that it is a Charger. Then when you navigate to them the battery will preheat as you want it to be around 95F to receive optimal charging. Otherwise, it will take long and after 30 min on the EA charger, you will have to switch to another one, or accept that you will be charged.
