The CCS-1 chargers in the wild today have a couple things that, in my opinion, are really poor technical decisions. 1. The CCS-1 standard is, per the standard, limited to 500A. This doesn't make much sense. Tesla pushes 700A through smaller connector with smaller DC pins, and limits dynamically...

I did the CCS retrofit on my 2019 Model 3 today (with the bundle of wires and new ECU). Sometime recently Tesla added a "CCS Retrofit" button in service mode. I was expecting to be able to use that to clear all the usual errors that occur after, instead of going through the software reinstall...

This is a V2 Supercharger plug (V3 is similar): Here's a V4 Supercharger plug... ...and Chargepoint's NACS plug... Both have gaps around the outer edge (between the DC pins at the top and on each side between the DC and low voltage pins). Why is that? Tesla's specs show this gap (page...

Apparently in the EU there is a mandated warning for phones that wireless charging is less energy efficient. This got me thinking - yes, wireless charging certainly is less efficient (no debate there), but does a phone even use enough energy for this to be at all meaningful in my overall energy...

This question seems to come up in Tesla circles every so often, and the conventional answer is "no, if you drive exactly the same speeds then acceleration mode does not impact efficiency". But Tesla has some interesting notes in the manual: So in weather cold enough to use cabin heating...

Got v11.4.7 (2023.7.30) last night and, strangely, auto-wipers were awful in some rainstorms today. Clearly worse than 11.4.4. In moderate to heavy rain they barely wiped and I could could not see well. Obviously, I couldn't safely test this too much without hitting the single wipe button for...

I had a surprising (in a good way) experience today. I thought FSD had no support at all for respecting No Turn on Red signs, but today it clearly waited at a red when it had multiple chances to make a right. Here's the dashcam footage (I wasn't recording with anything higher quality...

These pics were shared on the Denver Tesla Club Facebook page. Apparently there is a 4 stall Supercharger by the small airport in Gypsum, CO and another 4 stalls at the upcoming service center very close by. None working yet. These at the mall are here: Google maps link. Strange install, Tesla...

Now that FSD Beta has, or nearly has, merged with production releases for a release to the whole fleet... ...what will Tesla's release rollout and testing strategy look like? I've seen some people claim online that now the beta test program will just be over: only production releases that...

I currently charge off a Nema 5-15 120v plug at 12A. I have a roommate and I need to pay for car charging, so I'm charging through a Kill A Watt style meter. Works totally fine for at 12A and makes it easy to know exactly how much energy charging is using, including losses, preheating, etc...
