- The Tesla Mannequin 3 with an LFP battery pack remains to be completely usable after 110,000 miles.
- That is what one proprietor says about his automobile.
- Regardless of continually DC quick charging it to 100%, the battery has minimal degradation.
A number of the largest benefits of lithium iron phosphate (LFP) batteries, in comparison with nickel manganese cobalt (NMC) cells, are decrease manufacturing prices and minimal degradation over time, even when totally charged frequently.
Granted, LFP batteries as a rule have a decrease vitality density than their NMC counterparts, however the truth that most EV makers suggest charging them to 100% typically makes up for the decrease density. In the meantime, NMC batteries ought to be commonly charged to 80%, leaving full top-ups for lengthy journeys solely–this manner, the degradation ought to be minimal. (One research discovered that totally charging LFP batteries also can result in extra degradation, although.)
However how does an LFP-equipped EV really fare in the actual world? Fairly good, because it seems. As you’ll see within the video embedded under, revealed by Brandon Kipp on YouTube, this specific 2022 Tesla Mannequin 3 has proved to be a very stress-free possession expertise.
The automobile was inbuilt Fremont, California, and has up to now pushed almost 110,000 miles. It’s powered by an LFP battery pack that sends juice to a rear-mounted electrical motor. The automobile has been used extensively as a ride-sharing automobile in Texas, with a lot of DC quick charging and many metropolis driving.
In whole, the automobile has been DC quick charged with a whopping 22 megawatt-hours of vitality and almost 8 MWh of AC charging. Nonetheless, the drivetrain is unique and the automobile has by no means wanted any repairs–simply new tires and washer fluid, in keeping with the proprietor.
The automobile’s battery initially had a usable capability of 57.5 kWh. Now, after doing a little fast maths the place the whole driving vary of the automobile was taken under consideration after a full cost and an extended journey, the theoretical battery degradation is sort of spectacular, at simply 5%.
In line with Kipp, the utmost driving vary is now 258 miles, down from the 272 miles when the automobile was new.
The automobile has been continually charged as much as 100%, as per Tesla’s suggestions, which means the entire pack has been used extensively and with minimal degradation. That’s excellent news for anybody trying to get an LFP-equipped EV, which is normally cheaper than an NMC-powered one.Â
Related outcomes had been achieved by a number of different Tesla Mannequin 3 house owners, with some reporting degradation as little as 2% after 20,000 miles and round 5% after 85,000 miles.
LFP batteries normally have a decrease vitality density than their NMC counterparts, which ends up in a decrease vary score, however the upside is that they’re cheaper to make and most carmakers suggest charging them to 100% to protect their life. In the meantime, NMC batteries provide extra vary when totally charged, however the industry-standard suggestion is to solely cost them as much as 80% if you wish to decrease degradation and to go as much as 100% when you’ll want to take an extended journey.
All this being stated, Tesla discontinued the LFP-powered Mannequin 3 in the US in October of final yr, leaving simply NMC-powered fashions within the portfolio. However in the event you’re in search of a used EV, this is likely to be an important selection.
