Without a doubt my car loses around 1kwh/day. It’s not some recalibration. I’ve logged it via my enphase system for months. Still on my list of things to ask the dealer when I eventually bring it in.

The car doesn’t have enough information to properly schedule sessions, the wall charger does. It’s really that simple. Using the wall charger’s scheduling can save money, reduce grid dependence, etc. Not many people are morally opposed to saving money/the earth.

it can be useful without having a condescending tone. All the unnecessary parts about a EVSE being not a charger come across as condescending. English is a fluid language. The EVSE has become known as a charger by the general public. The whole an EVSE is not a charger crowd have lost. And my...

I’m a EE and this all still sounds like an unnecessary pedantic rant. I have no issue with non tech people calling an EVSE a charger. It’s a required part of the home charging system. I still call usb c cables charging cables because that’s all I use them for. Who cares that it’s basically just...

The car has been parked since July 3rd. That seems like plenty of time to establish a baseline before the app update. The only interesting thing that happened before the app update was it switched from 9.8kw charging to to 2.5kw charging around week 3.

I never wanted to discuss the 30w *equivalent* base draw. My original post was about the app update. Since the update , I’ve noticed frequent 24 hour charging, regardless of draw that’s unusual. Note the word “equivalent “. I’m assuming any power usage is due to a parasitic loss. No way to...

Amazing levels of certainty here. Sorry if I don’t take your word for it. I’m an experienced engineer that’s worked on plenty of similar systems. Things don’t always work the way you expect. Polling for status is a pretty common issue, it absolutely can drain a battery. You are also...

I know for a fact it’s charging. I get notifications when it finishes and it always stops at 50%. Either it lying and charging to more than 50% or the battery has drained by at least as much as my fairly reliable energy tracker is claiming (I have not adjusted for charging losses, but a quick...

My reading of those threads was it was parasitic drain issues. Many people suggested a SW issue.

Google is your friend. Literally the first hit:

It’s obviously impossible to have zero vampire drain. We’re talking about ~30w average before the app update and 60w after. I have a trickle charger on another ICE car and it pulls 10w pretty continuously. And cellular connections + some less efficient electronics can easily add up to 30w. I do...

I hope that is sarcasm. The Taycan forums are full of excessive vampire drain issues. And every electric car has vampire drain. The question is how much.

The data is what the data is. I’m attempting to collect more. We shall see how it goes. But the fact is it increased the drain after the app update. Correlation is not causation but doesn’t mean it not the cause.

Garage temperatures for the last 4 weeks to confirm what I said about it being cooler.

Also even at the original drain rate it was going to use ~30kwh. At 50% the car has ~47.5 kWh. At current rate it would use everything and unless it has working built in protection a dead battery. It’s possible by leaving it plugged in the live tracker switched to polling instead of...

My understanding is waking the car drains the 12v which gets charged by the high voltage. So in essence the app polling the car causes a drain on both batteries. I can totally imagine the high voltage being woken is enough to cause an accelerated drain. If the pattern held iit is draining at...

The apple App Store seems to have no idea what today and tomorrow are here in Japan. It’s already past midnight here (so the 9th) and it still says the Porsche app was updated yesterday. An app I manually updated yesterday still says Today and one I just updated says yesterday. It’s just...

It just says “yesterday” in the App Store. I know I’ve seen 3 charging sessions on my Lock Screen and in the status island thing. The data from my energy tracker confirms 3 charging sessions roughly 24 hours apart.

Here is Japan, but I use the USA App Store. No idea how apple decides when to release an update. Can easily imagine it’s phased by location of phone not App Store. Fromanother thread it was stated that checking the app turns on the high voltage battery to charge the 12v battery. Between that...

I’ve seen 3 charging sessions since it updated. Maybe it was released earlier here? My phone auto updated and I started getting live updates at least two days ago. Only reason I looked at the data to see what was going on. it’s very clearly the high voltage battery. Why would it need 3kw to...
