We all know that lithium batteries should be avoided in daily use, as much as possible, as these will have an impact on the life and safety of the battery. Almost all electric car manufacturers have told consumers that it is best to charge 80%. However, Tesla always has some abnormal operations. Recently, overseas media reported that Tesla has released its latest car use advice, suggesting car owners charge up to 100% regularly every week to ensure battery life.
Tesla said it is recommended that the Model 3 rear-wheel drive version with lithium iron phosphate battery (LFP) should be set to 100% even for daily use, and charge to 100% at least once a week. In addition, if the vehicle is parked for more than a week, Tesla recommends charging to 100% as early as possible.
It is reported that there are currently many Model 3 models in the US market that are made in China and are equipped with lithium iron phosphate batteries, so users need to perform specific charging behaviors. Car owners can use the "Settings Limits" set on the charging screen to determine whether they are equipped with lithium iron phosphate battery . If the battery image shows "50%" and "100%", the vehicle is equipped with a lithium iron phosphate battery pack, and if the image is changed to "Daily" and "Trip", the lithium iron phosphate battery is not equipped.
Officially stated that following the above suggestions, users can maximize the available mileage of the vehicle and improve the vehicle's ability to accurately determine the charging status and estimate the mileage. Here we will talk about the characteristics of lithium iron phosphate batteries. Since the battery voltage of lithium iron phosphate cannot stably display and estimate the accurate voltage value of each battery cell like a ternary lithium battery, in order to better manage the voltage situation uniformly, the battery pack needs to be charged to 100%.
Therefore, Tesla also recommends that users equipped with ternary lithium battery vehicles charge to 80% or 90% in most cases to slow the battery down in long-term use and ensure that 100% of the total battery can be used during long-distance driving. This is like what I mentioned above, ternary lithium batteries are not suitable for saturated charging in daily life.
Editor said: As soon as I saw this news, I thought Tesla was operating abnormally? Isn’t this a big conflict with our usual cognition? However, objectively speaking, this is also reasonable. After all, the characteristics of different battery materials are different. Tesla just gives a more reasonable way of use based on the actual characteristics of the battery. Of course, according to Tesla's usage recommendations, it is still unknown whether it can really maximize the available mileage as it says. It takes a long time for users to observe, and they cannot even observe the specific numerical differences.
Interestingly, Stella 's suggestion seems to be more aimed at American users, and no formal suggestions are issued for users in other regions. So as a domestic user, would you be willing to listen to Tesla's usage suggestions, or would you continue to charge to 80% or 90% like a ternary lithium battery in the past?
