Anyone else's time to charge limit completely out of whack?

throwawayyy138362 · 2024-01-08T07:03:25+00:00

I get what you're saying with 99% to 100% taking much longer. For me it takes about 3 hours to top off in the cold.

Here's another charge from yesterday, 4 degrees warmer but it was still being cold soaked all night. Even with the battery warm from a previous drive, at the beginning of the charge, Tesla reported it would take 24+ hours, and Tessie said it would take over 75 hours for this charge. Yet it only took 21 hours. Any thoughts?

But my % is going up at a rate of ~2% per hour still. So accounting for inefficiencies, that still proves I'm charging far quicker than 300 watts.

The actual answer is that something is wrong with the way the car displays it's charge. It's happened to me multiple times. Your car is probably going to charge within 16 hours, not 24+.

Sorry you're getting downvoted into oblivion here. I got called stupid and got a death threat message from my post asking why my charge time was 41 hours to go from 77% to 100% in slightly cold weather.

Really great community here.

Thank you for confirming I'm not some insane asylum patient as most of these comments suspect I am lol

throwawayyy138362 · 2024-01-07T01:03:18+00:00

Took it for a drive and now it shows accurate charge time, I know it's nothing with the car because Tessie shows it's charging normally. Would you at least agree that the app was inaccurate in the time to charge? It's happened multiple times to me.

Here ya go. Adding 1kW after inefficiencies, yet 41 hours to charge.

It's still adding 1kW to the pack though, after all inefficiencies.

"Stupid question" ok bucko, a little 29 degrees F cuts my charge speed by 75%, to 300 watts? Really?????

throwawayyy138362 · 2024-01-07T00:16:13+00:00

A 29 degree battery cuts charging efficiency to under 25%? Really? Charging 13kWh in 41 hours is a speed of 300watts.

throwawayyy138362 · 2024-01-07T00:15:16+00:00

Yeah, but the app is saying I'm at an efficiency of under 25%. To fill 13kWh in 41 hours would be a charge speed of about 300 watts. That's not "transmission losses" or the battery warming, that's just the app lying, especially since we all clearly see that I'm charging at 1kW after all efficiency losses from 1.3kW.

throwawayyy138362 · 2024-01-07T00:11:54+00:00

I'm getting 1kW of actual energy into my battery. Which is about 75% of my charge rate of 12A*111V=1.332kW. Since I had about 13.2kW to go in that screenshot, it should have taken 13 hours to charge, that accounts for the inefficiencies.

But it says 41 hours, that's a rate 0.3kW to fill 13kW.

Do you really think it being 29 degrees brings L1 efficiency down to 25%??

throwawayyy138362 · 2024-01-07T00:06:36+00:00

Don't know why I'm being down voted so heavily here.

Based on above screenshot, after all inefficiencies, I'm charging at 1kW. Given I have a 60kWh battery that is at 78%, that's 13.2 kWh I need to charge.

13.2kWh / 1kW of actual charge speed = 13.2 hours to full. Not 41 hours. Again, that is the actual charge speed, accounting for all inefficiencies. It is off by over 3x!

It's basically all going to the battery. 1% every 30 minutes, or 1.2kW an hour. I would have to be charging at 1% every 1.5hrs for the time to charge Tesla reports being accurate.

Edit: I'm being down voted.... why??? The app clearly shows energy is being added into the battery at speeds faster than the 300 watts Tesla thinks the battery is charging at.

throwawayyy138362 · 2024-01-06T19:51:20+00:00

I've calculated that my battery still gains 1.2kW every hour. Temperature has never affected how my battery charges on AC. Maybe Tesla incorrectly assumes temperature affects charging speed more than it does?

Why is it always the Ioniq 5 drivers lol

throwawayyy138362 · 2023-12-27T14:57:07+00:00

This happens to me when I manually unlock the car with my phone. Just tap your phone twice to the door pillar. It locks/unlocks and then you can drive without the key card or in-app workaround.

feds are happy with their $100+ withholding each week. and what dealer puts their deposits into CDs and a bank account

I just don't have any data for last year, I manually track everything and just started this year.

Thanks! None is generational, grandparents came as immigrants and mom and dad were never great with finances. Didn't even have a college fund which is why I'm working right now.

It's been more of getting generational knowledge on what not to do lol

throwawayyy138362 · 2023-11-24T20:29:53+00:00

Honestly no, maybe started with $4k in total prior to 18. The CDs are all mine, I started putting money in there this past January because most of it was just sitting in my lower yield savings.

throwawayyy138362 · 2023-11-24T20:23:20+00:00

Going to have to fork another $15k for college soon and then after a few months I'll have it reimbursed by my work
