Cybertruck bricked

You must have some fun road trips. ?

This is why Tesla doesn't put it in the owners manual. People like the hoi polloi are too dumb to understand the difference between soc for battery health and maximum soc for road trips.

Tesla: "To maintain service life, the battery pack should be stored at a state of charge (SOC) of 15 to 50%."

Maybe this used to be in the service manual, but it is not currently. I searched the owner's manual, service manual, and the DIY manual.

Google search just brings up the chat posted in this forum or on reddit. Nothing official from any Cybertruck manual.

What's the difference? The battery degrades whether you are using it or not. Using it makes it degrade more not less, so in storage it is more resilient and you should be able to keep at a higher SOC not lower.

I sincerely have no idea why you are confused on this topic.

If you think Telsa is telling people to keep their vehicle charged at 15% for daily usage, then I question your eligibility to safely drive down the road at 80+ mph with a 6,800 lb robot on wheels.

Same, start of the "50% Club" incoming

Same here... We should make T-Shirts!

That quote in under section 17:00 which is a California requirement for storage of batteries. They are referring to batteries before installed in (whatever). It's a general statement - in fact in the same paragraph they also state not to stack more than 2 packages high.

In all the years I have owned a Tesla car (2013), Tesla, nor any documentation has ever said to keep the battery at that state of charge. In fact, as someone else pointed out, you can't even set the level of charge in the car or app below 50%.

Calendar degradation is significantly reduced below 55% SoC. This applies to “storage” but your vehicle spends 90%+ of the time idle.

There’s no harm below 20% SoC, other than the risk of being stranded, and for this reason some features will be disabled (like Sentry).

Charge as high as you need of course, but you will experience lower degradation if you can keep your typical idle SoC under 55%.

Well I can tell you from personal experience. My first Tesla, purchased new, a 2013 Model S P85, had over 125k miles on it when I sold it after 6 years of ownership. It had free supercharging which I probably used for about 1/3 to 1/2 of that total mileage. The car was charged to 80% as my daily driver and 100% often for many of my cross country trips. When sold that car in 2019 it had only degraded 11-12%. This number (at that time) fell in line with many others, some which had supercharged 100% of the time and others that had only charged at home.

Perhaps for people not using their cars and store the batteries at 50% or less long term may see a 1 or 2 percent battery health improvement over 6 year, but I would question that. Plus, I purchase my vehicles to use. I put 10k miles in my CT in the first 4 months.

I wouldn't worry so much about the details. Do what Tesla recommends. Leave your vehicle plugged in when not in use and daily charge to 70-80%.

Anecdotal evidence is fine, but the science is clear on this matter: high SoC increases calendar degradation.

That said, even an abused pack will last hundreds of thousands of miles for many many years. You don’t need to worry about it if you don’t want to.

My Miata lasted 25 years, even though my oil changes were like 4 years apart lol

That's the charge LIMIT not the charge the battery likes to be at.

You were not talking about "likes" you were referring to Tesla's recommendation:

Tesla recommends 15-50% so technically you should NEVER charge above 50%

I provided a Tesla source recommending 80% for daily driving.
You are linking to 3rd party videos and Tesla documents regarding long-term storage of packs without active thermal management.

Will high SOC increase degradation? Yes.
Does Tesla recommend people only charge to 50%? No.

 

[Crissa]

Don't take my word for it.

Why is it your support links don't argue with the others?

This is why Tesla doesn't put it in the owners manual. People like the hoi polloi are too dumb to understand the difference between soc for battery health and maximum soc for road trips.

Maximum SoC for road trips is 'as much as you need to get to the next one'.

Why? The lower the choose, the faster you get on the road; the shorter your overall trip.

But you're also not 'storing' it since you're using it immediately so 100% is fine.

Exactly that's the difference.

 

[Crissa]

Exactly that's the difference.

Which is the same with charging it back up to 80% when you plug in - the average distance driven is 40 miles (plus backgroud loads like network, sentry mode, thermal management) so any next day it's likely you'll consume at least 15% of the battery charge.

Can we get back on topic please? Thread is about bricked trucks not soc best practice.
