How Much Should You Charge Your Tesla

By Henry Farkas

There’s an article in “The Drive” that’s been repeated in other media. Here’s a link if you want to read the whole article.

It’s not important in your day-to-day driving since few people use up all the electricity in their Tesla on a normal day. But, if you have lots of driving scheduled for a day, or if you’re taking a cross-country trip, you have to make allowances for this particularly Tesla problem.

The Results of the Tests

Edmunds, which does reviews on all cars, and which has rated the Tesla Model 3 as the number one best electric vehicle, found that none of the models of Tesla met the EPA range estimates as advertised by Tesla. None of the models. All the other electric cars easily went 20 to 50 miles past their EPA-rated ranges.

How Much Should You Charge Your Tesla

Tesla’s Response

Naturally, the Tesla engineers weighed in, but what they said was not very helpful. They said that the reason the Teslas failed to reach the EPA range is that Edmunds didn’t keep driving them until they couldn’t go an inch farther. Edmunds stopped driving when the range number on the screen went down to zero. So Edmunds repeated the testing and kept driving until the cars actually stopped. Tesla calls this a safety buffer.

Don’t Plan on Using the Safety Buffer

Don’t plan on using the safety buffer. It’s terrible for the battery. It’s just as bad as charging your battery up to 100% and then letting it sit overnight. Don’t do that either. Bad.

Be Kind to Your Battery

We want our batteries to last as long as the rest of the car. So, in my case, I charge to 80% every night. That way, I’m not damaging the battery, and I have more miles than I need for day-to-day driving. I do plan on taking the Tesla on road trips once this furshlugginer pandemic is over. I have the SR+ which, in theory, can go 250 miles on a charge. I won’t plan on 250 miles between supercharges. When my car was new, and I had 1,000 miles or six months of free supercharging, whichever came first, I didn’t actually need any supercharging. Not going anywhere. Pandemic y’know. The six months came first.

My Supercharging Experience

But, since supercharging was included in the price of my car, any time I needed to go somewhere near a supercharger, I went ahead and used the service. Here’s what I found. When the battery is low, the supercharger gives extremely rapid charging. I can’t tell you the exact rate of charge because different superchargers give different rates of charge depending on which generation of supercharger you’re using. But as a general rule, you’ll get extremely rapid charging when the battery is low. You’ll probably get to 80% in 30 to 40 minutes. That last 20% will take longer. A lot longer.

Suggested Strategy

You’ll probably do better in total trip time if you don’t wait around for the last trickle of energy to fill your battery to 100%. Between 80% and 90%, the charging goes painfully slowly. Between 90% and 100%, the charge slows to a trickle. You’ll stop a bit more often, but you’ll spend less total time on the chargers during your trip if you just charge to 80% each time you need to charge. When I take my trip, I’ll be sure to let you know how it goes.

Public Health Advice

One last thought for car trips. Elon Musk gives you video games to entertain yourself during a supercharger stop. If you’re on a trip, don’t play the video games. Get out of the car and walk around. Sitting in a car for long periods of time can cause blood clots in your legs. Don’t let that happen.

Tesla FSD V12.5 to Enable Sunglasses-Friendly, Nag-Free FSD

By Karan Singh

Tesla has made some significant improvements with FSD 12.4, primarily, the removal of the steering wheel nag under certain conditions. However, there’s a caveat – you can’t wear sunglasses.

According to Elon Musk, FSD v12.5 will introduce support for nag-free FSD, even if you’re wearing sunglasses.

FSD V12.5 is an Upgrade

Ashok Elluswamy, Director of Autopilot Software, also took to X recently to mention that v12.5 is a big improvement to FSD v12.4. While he didn’t mention any specific details, this lines up with some of Musk’s previous comments that each FSD v12 iteration will see major improvements to the FSD model.

Elon also mentioned that while Tesla has a massive fleet of cars, their laser focus on making FSD work, rather than touting every daily achievement – has been their key to making generalized self-driving cars work.

FSD v12 has been pretty much a complete rewrite of the FSD city streets software stack, with drastic improvements over FSD v11. However, certain parts of the software stack haven’t been updated yet. Some features, like the updated highway stack are expected to be in FSD v12.5, which Musk confirmed recently. However, other features such as Park Seek and Banish Autopark, which were expected to arrive with FSD V12.4 are still up in the air.

What about V12.4?

FSD V12.4.3 is currently out to about 5% of the fleet (about 20-25% of FSD users) and hasn’t been pushed out again since about July 10th. Our new auto updating statistics pages can help break this down for folks who are curious.

Given that it’s been some time since any new vehicles have received V12.4.3, it seems the rollout has been stopped. There could be any number of reasons for this – including software bugs, or a lack of confidence with FSD. Additionally, it could just halted in favor of focusing resources on V12.5.

While we’d love to see more vehicles get v12.4.3, we’re likely to see v12.4.4 or v12.5 being the next big waves of deployments to customers. Either way, early-access testers and Tesla ADAS testers will receive these updates first, and then they’ll roll out to the vast majority of customers once Tesla feels confident there aren’t any major issues. Tesla does all this testing in the name of safety, and it's essential that bug-free versions of FSD are the versions that are rolled out wide.

So, for now, leave your sunglasses on and hang tight for the next FSD update.

Tesla Aims To Launch Cybertruck in Canada After Transport Canada Makes Exception for Steer-by-Wire

By Karan Singh

Tesla has confirmed that they’re aiming to launch the Cybertruck in Canada later this year. Transport Canada recently granted Tesla and the Cybertruck a unique exemption to allow steer-by-wire functionality (h/t Sawyer Merritt).

Steer-By-Wire Exemption

We previously reported that the Cybertruck was facing delays due to a steer-by-wire regulatory issue with Transport Canada. On Friday, July 19th, Transport Canada issued a message stating that they would exempt the Cybertruck, for all its models, from part of Canada’s Motor Vehicle Safety Act, which currently doesn’t permit the usage of steer-by-wire systems.

The period that the exemption begins seems to be immediate – July 19th, 2024, and will last through July 18th, 2029, whereafter regulation should supersede the exemption. In the meantime, Tesla will provide a semi-annual incident report, beginning on January 18th, 2025, including information on steering system malfunctions or failures, as well as corrective measures and customer complaints.

It seems that Transport Canada will also have to be notified every time Cybertruck’s steering software is provided with an OTA update, which could result in some update delays in Canada.

Canadian Cybertruck Soon?

With all this information, it sounds like Tesla is aiming to launch the Cybertruck to Canadian customers sometime relatively soon, as they stated they’re still aiming by the end of the year. There is a good chance that they may begin converting pre-orders to orders once Tesla. Tesla hasn’t commented on which model will be available in Canada, but it wouldn’t surprise us if it’s limited to the Foundation series in Canada in the initial release.

We could expect the first customer Cybertrucks (Roshel Defence and a few private importers notwithstanding), to be on Canadian roads in just a couple of months.
