Charging habits

[JohnJ85]

Hi everyone quick question I do 40 miles a day commute to work and when I charge my car I set the limit to just over 90% is this ok for the battery considering im covering a lot of mileage per day?

You dont say what car you have. For all non LFP cars it's now 80% and for LFP cars you just charge to 100% and forget about it.

30 miles commute is considered average daily. Being that you car will be able to to at least closer to 200 per day, this is not really allot of mileage.

Which variant? Standard Range? Long Range? Performance?

 

[JohnJ85]

Which variant? Standard Range? Long Range? Performance?

Standard range plus

 

[Js1977]

Long range and performance model will be 80% . If long range rear wheel drive or just model 3 standard range its 100%.

 

[Js1977]

Standard range plus

What year?

What year?

2020

That won't be LFP. Charge it to 80%.... also make sure you have updated it as it should say in the app/car what to charge for daily use.

But if I charge it to that I'm literally charging it every other day, on current charge limit I'm every couple of days, unless I let the battery run to under 10% which isn't great for it also right?

At 40 miles per day, I would say you want to charge it every 3 days even this time of the year to be comfortable (we used to have a 2020 SR). If you have at home charging, you just charge every day or every other if you have two cars and one charger.

Do you charge at home or somewhere else? If it's at home, is there a reason you can't charge every day?

From the manual:

Model 3 has one of the most sophisticated battery systems in the world. The most important way to preserve the high voltage Battery is to LEAVE YOUR VEHICLE PLUGGED IN when you are not using it. This is particularly important if you are not planning to drive Model 3 for several weeks.


There is no advantage to waiting until the Battery’s level is low before charging. In fact, the Battery performs best when charged regularly.

I do have a home charger but even so bit of a faff charging it every other day, is it right that the battery level shouldn't drop below 20% as it's bad for it or is this another strange myth?

At home mostly, and no just a bit of a faff charging it every day is all

You must be particularly faff averse. Takes me less than 10 seconds to plug in and probably 15 to unplug, but I do have a charger with a tethered cable. It's much less faff than buying new diesel once a week.

Not sure about LFP but if I get home below 20% I charge immediately (well, enough to get higher than 20%), rather than let it sit "low" until overnight cheap rate.

LFP is happy being regularly charged to 100%, but for non-LFP I only ever charge to 100% shortly before setting off. Again, not good to let it [non-LFP] sit there for prolonged periods.

But ... there are Airport Taxis that have charged to 100% overnight, every night, and been left at that level until the driver sets off tomorrow, and also regularly charged at Supercharger ... and no significant ill effects noticed.

I have my charger where I park ... so when I come home I park and plug in. But, yeah, if you have to do car-shuffle on the drive to get the right car next to the charger, or something like that, I can see that would be a hassle.

My view is that I MIGHT need to go somewhere tomorrow, and I'd like the car to have plenty of charge. Can't remember the last time that happened though ... but I have had family illness, etc., where I have needed to "go far, unexpectedly", and its not like Petrol where a fill-up is only 5 minutes.

Or the layout of the O/Ps driveway and charger location doesn't lend itself to come-home, park, plug-in ...

Or, perhaps, "not developed that habit yet"

Just charge it every day if it's the only car you have.... get in, plug it in. .. Not because you have to but its just a good habit

It is probably due to the fact that I don't have a tethered cable and have to get the cable out of my boot every time, not so bad when it's not raining but when it is, yes it's a faff lol
