⚡️ Home Charging Issues after Software Update? (Tracking Thread)

[alxman]

Mine did not come with both adapters. They told me they banned the 120V plug due to fire hazards, so that’s why mine didn’t come with it.

I really hope they find a solution for your charging problem. Overall, the vehicle is a pleasure to drive. Perhaps you will eventually get to enjoy it for many years and just remember these struggles as a bad nightmare.

I purchased a Grizzl-E mini connect charger which allows me to change the current limit in Amps by using their app (Highest 40a/Lowest 7a), and also you can set it manually using the dip switch inside the charger (which would require me to open it up and restrict it). I have tried the app route so far, and no matter how low I set it to, the car still won't charge. I haven't done the manual restriction yet because it's a pain in the ass to do I'm a tiny lady at 5'2" tall, and my outlet is so high up I need to carry a heavy ladder over from the opposite side of the garage over a couple of steps because my car is in the way.
....

Just to note that this setting does not change the voltage the car sees nor does it regulate current. This flips a switch that tells the car the max allowable current. Its up to the car to regulate the current it draws. The only thing the Grizzl-E does is monitor current and disconnects the car if it draws more than allowed, like a circuit breaker.

I have had a Grizzl-E classic for going on 5 years. A well built and reliable EVSE.

I ended up buying a Vevor Level 1 Charger from Amazon to allow my vehicle to be plugged in and charger at the airport. You can find options for about 140-160 CAD, and it may be worth a try to see if you can get charging to start on 120V. For some of us, the reason we are then adding a 120V voltage regulator, it is to make sure when we feed our level 1 charger with a stabilized voltage to get the car to start.

Following the car starting the charge on Level 1, I am just pushing the green button and plugging in my Level 2 charger, and that for whatever reason has worked.

So far, no fires. Will keep an eye out for one.

My dealer is FINALLY talking to Porsche. They forwarded the attached questionnaire from Porsche for me to fill out which I did along with a detailed description of the problem. Porsche followed up with asking for the exact 120 and 240 voltage at my house and the serial number of the Grizzl-E charger. Note the questionnaire asks for things like ambient temperature and charging power of 3rd party chargers. Don't know if this is a generic questionnaire or one created for this problem, but this is the first evidence they have shown me in 3 months that they are taking steps (baby steps) to at least look at the problem. And it might also indicate that they are thinking along the same lines that others on this forum are.

seems a generic problem form given its has sections for DC charging and some other data not relevant to this particular problem

but I agree 100% it seems like progress…

The US is something I’ve always used as a quality measurement regarding the excellent customer service it has across the states, no matter the business category. But seeing the unresponsive dealers being consistent with almost all the issues involving NA customers is really surprising to me, especially with a brand like Porsche. It’s not that they’re unwilling to actually help you out, they even make you fill out a questionnaire as well (?!). I’ve had maybe 10 issues escalated to Porsche AG, and the only thing my dealer did at most was ask for photos so they could forward them, but this is next level.

My dealership confirmed that Porsche NA is well aware of the issue specifically in the Mid-west region of USA. They are also in touch with Comed but they know they need to fix it asap.

I have no doubt your dealer told you that…

if only I could believe what they told you…I hope they are right and not pulling your leg.

I'm just satisfying my curiosity at this point, but another data point, if there is any interest.

Line voltage had been varying, mostly between 246VAC and 247 VAC. Once in awhile dropping below 246. The VAC stayed pretty close to 246.5 between the time I plugged in and the EVSC contractors kicking in. But It took a long time, in excess of 90 seconds. The VAC stayed pretty close to 246.5 during that time, and, when the EVSC kick the relays, it dropped to 242 VAC. The Macan indicated a 9.1 kw charge rate.

I agree 100% that the vehicle is a pleasure to drive. And now that I have first hand experience, I can understand the saying "drives like a Porsche", or why ppl are loyal to the brand despite its shortcomings. However, if Porsche is charging this much for their vehicles, I think their customer service and software quality level needs to align better with their price point. Their whole branding is about quality. Whether it'd be the driving experience, or reliability, or resell value. When their vehicles have problems and they're not fixed in a timely manner, who would ever want to buy into that? I'm baffled as to why they don't adopt OTA updates like Tesla. Tesla's software is way better, not to mention their cameras, and parking mode aka Sentry mode. If a car half the price of a Porsche can have such good cameras integrated, why can't Porsche?

Just to note that this setting does not change the voltage the car sees nor does it regulate current. This flips a switch that tells the car the max allowable current. Its up to the car to regulate the current it draws. The only thing the Grizzl-E does is monitor current and disconnects the car if it draws more than allowed, like a circuit breaker.

Thanks for letting me know. I did find out it does nothing, so I didn't even bother trying to adjust the dip switches. Do you use the Grizzl-E app? I have the Grizzl-E mini connect, which has wifi connectivity, and for some reason, the charger doesn't close charging sessions after I disconnect it from the car. And it's not logging charging sessions correctly because of it. I would have to manually disconnect charger on the app or switch it to scheduled charging before it closes the session.

Like Feb 19th, my charging session apparently lasted for 115hrs. Last night, I powered it off to close charging session, and as soon as I powered it back on, it started a session even though the car wasn't plugged in at 6:24pm.

Based on last night's charging, my voltage ranged from 229v-243v. Sometimes it can go as high as 247v

My dealership let me know today that Porsche Germany sent engineers to the US to investigate this matter. They didn’t say where in the US, but perhaps Chicago as there is a good chunk of us here that’s from Chicago. Hopefully something comes out from this trip.

As stated here and in other manufactures forums, there are Tesla owners (fanboys) that don't know what they don't know that think the world of Tesla software, but others that understand it is dangerous crap covered with marketing BS. Their support forums are full of issues. Technocrat owners seem to love the user interface, and being beta testers, others hate it. Otherwise it is a different business model where OTA is a must to deliver the numerous safety fixes to half baked products. Otherwise they would have been out of business years ago. They are overall terrible cars as transportation appliances go with only a few redeeming features, like being an EV.

It s not the business model most major manufactures use or dare to use.

....

I have a Porche wall charger used primarily for the Macan, and a Grizzl-E clasic I use primarily for the Mini. I've turned off the Grizzl-E wifi because its software requires a reliable internet link to the mothership to authorize charging. I gathered quite a bit of BMW charging characteristics knowlege before I turned it off. Knowledge I have not used for years as I found BMW engineering to be smarter than me and now I just enjoy driving it. I have charged the Macan with it, but not recently. They are both set up as dumb EVSEs as is way more reliable/dependable.

No question some of the quirks are frustrating, and there are a few problem children, but its not unusual in the industry. By far most owners do not have software problems. There seems to be buggy feature sets that British owners have to deal with.

Personally, I don’t have a lot of experience with Tesla myself, and I would never buy Tesla. I just keep hearing so many good things from friends who own Teslas about their software and how fast and easy it is for them to patch software through OTA updates. And how insane they think it is that I’m experiencing these issues for 3 months and counting. Their passenger is also able to stream from their plex server when they’re waiting for their kids at school or at sports practice. Me, I have the passenger display and it’s useless Can’t stream from my server or Netflix for that matter. But Teslas can!

I did rent a Tesla Y on my trip to Iceland since their EV infrastructure is amazing. And I have seen how good their cameras are. Tesla wins hands down with their cameras. Driving experience and handling, we know Porsche wins it day in and out.

As for the grizzl-e charger, I am part of their club so we get cashback from charging and I think it needs to be on wifi in order for that to work.

The BMW mini’s all electric has low range right? Before I settled on the Macan EV, I considered the BMW iX. Our next EV might be a BMW.
