For the entry-level rear-wheel-drive Tesla Model 3 with the lithium iron phosphate
Recently, Tesla updated its Model 3 owner''s manual for the US with charging
Model 33.6993.899,2000（1.3）。
The main battery pack on your Tesla vehicle costs several thousand dollars to replace. Because of this, you are, quite naturally, concerned about maintaining the battery to improve its life span. And one of the important factors that affects the lifespan of the battery is how you charge it.
There have been a lot of questions about the best charging practices for a Tesla vehicle battery, especially the question of whether it''s ok to charge the lithium-ion phosphate (LFP) battery to 100 percent.
On this subject, you will get many opinions and so-called best practice recommendations from different sources. But, as I always say, there is no better place to look than the vehicle manufacturer itself and factual scientific information about the subject.
So, in this article, I will answer all the questions that you have about to what percentage to charge the LFP battery on a Tesla vehicle, and provide other best practice recommendations on how to maintain your Tesla vehicle battery using recommendations from Tesla and basic physics.
It depends. The answer is in your vehicle, literally.
All of Tesla vehicles, no matter the model and model year, use lithium-ion batteries for the main battery pack. However, they are not all the same. The batteries differ in the chemical composition of the cathodes as follows:
The last two cathode chemistries, NCM and NCA, are so energy dense that they are best suited for the long range versions of Tesla vehicles. The lithium-ion phosphate cathode chemistry is less energy dense, less expensive, and best suited for other Tesla vehicle versions.
Each of these battery chemistry types have their recommended maximum charge limits but their minimum charge limits are all the same.
And that''s why Tesla never recommends a single value for all their vehicles'' battery charge limit. Instead, here is what Tesla have to say on to what percentage you can charge your vehicle''s battery:
From this, it is immediately obvious that there is no set figure for charging all Tesla vehicles.
So, if your Tesla vehicle comes with lithium-ion phosphate batteries, simply refer to the recommended daily limits on your vehicle touchscreen to know the charge limit that is best for the vehicle.
So, when people ask the question of whether it''s okay to charge a Tesla LFP battery to 100%, I always say to them, follow the recommended limits on your touch screen as that is what''s best for your vehicle.
I will provide details about the things that do affect the lifespan of your LFP battery later in this article.
The takeaway from this section is that the answer to whether you should charge your LFP Tesla vehicle battery to 100% is, if Tesla says it''s okay on the touchscreen, then it''s really okay. You cannot get better information about this from anyone outside Tesla.
The simple answer is, as often as you need to. Daily, if you have to. The important thing is to never let your Tesla LFP battery fully discharge. And do not charge it beyond the recommended charge limit on your vehicle''s touchscreen. Other than this, you are quite okay charging it even more than once a day.
To appreciate this, I must explain a few things about lithium-ion batteries:
● They have more than 5000 cycles in them before they even begin to degrade
● Zero maintenance is needed
● They have 2% self discharge per month under normal conditions. Just make sure it is disconnected when not in use for long periods
Now that I have, I hope, answered all your questions about whether it''s okay to charge your LFP Tesla vehicle battery to 100% and everything else there is to that, here are detailed recommendations on how best to charge and maintain your vehicle''s LFP battery.
As a rule, try to avoid keeping the battery below 20% charge for an extended period of time. When the battery is too low in charge, the battery icon will turn yellow and the available range will drop if the vehicle is parked in colder temperatures.
