Tesla Roadster Batteries Are Finally End of Life | Gruber Motors

- The Tesla Roadster started the Electric Vehicle rEVolution.
And now, 15+ years later, the main batteries may finally be starting to die.
The original Tesla main battery design engineers were targeting a 10 year service life as cars were being released in 2008. We were all pleasantly surprised to find the majority of Roadsters still driving and functioning.
In today's video we delve into an alarming trend we are beginning to see in the main battery pack, related to not the original packs released in 2008, but a replacement pack released in 2016, designed to extend the range and life of the packs.
It seems 2016 upgraded Roadsters are beginning to suffer from a loss of power eventually so severe, it renders the car undriveable. We believe this may be early indications of an end of life failure mode, and a possible predictor of similar main battery demise in the next generation Teslas, the Model S, which also uses 18650 cells.

15 yrs life on a 1st generation EV is beyond insanity 😳
15+
But it's not 15yrs.. he's saying the 2016 battery is failing.. the original pack is still working...
Roadsters are 2nd gen EVs. 1st gen had more primitive battery tech.
You are at the leading edge of practical EV battery experiences. Very important to Tesla, Tesla owners and the EV industry in general. Your persistance is a major contribution as we are electrifying in the West.Keep doing what you are doing! Thank you.
My 2010 Roadster is still going strong with its original battery pack.
A common occurrence My Roadster VIN 5 still has the original pack as well and gets over 150 miles range..
That almost sounds like the replacement pack was an attempt at a night nickel chemistry. More buckle and less cobalt makes for higher energy density but the NCA cathode form cracks with less cycling.
It would be nice of Tesla to make whole the people who bought the 2016 pack. Those early adopters were critical to the early days of Tesla.
Definitely!
Arent they under warranty?
@@Cjdergrosse Warranty on this pack was 2 years.
@@grubermotorcompany oh boy. Well... I'm sure that wasn't any kind of secret. But anyone who replaced a pack that wasn't already completely dead is probably kicking themselves. Tesla should go above and beyond their warranty though. It would be the right thing to do after delivering a pack with substandard cells.
Not with Elon up there
ACPropulsion with alan coconi came up with the18650 cells in sheets. It turned out to be a very good design.
Those 2016 packs seem to have poor cells and should be replaced under warranty.
Martin Eberhard had great success using these types of cells in an E-Books business, and commissioned ACP to convert one of the three Tzero's from AGM Lead Acid with 80 miles range, to Li-Ion which brought it closer to 300 miles, and the rest is history, Tesla that is.
Batteries in the doors, and thermal management were the next challenges although Alan had crude thermal sensing mounted on top of each Optima Spiral Wound 12V battery (28 of them).
Thanks, Pete. Well done as always.
Excellent video!! Informative.
Great video with excellent information that was presented very well. Wish that was the norm on this platform!
at 5.24, a few years ago I was going to put together a ev having the batteries in the frame, recently I've started to try to put together a prototype of the next best thing in performance in EV's like the supercharger or turbo was
Boy I would really love to join your TEAM ! I love this stuff !!
Might a 2016 Tesla Model S suffer from the same battery problem as these 2016 roadster replacements?
The early MS's are now going on 11 years with no indications of similar high impedance weak cells. So far, it appears issues we discovered are confined to 2016 Roadster replacement packs.
@@grubermotorcompany Thanks for the reply. You guys are GREAT! 😀
@@grubermotorcompany Ahh, okay, because around the 7 minute mark you mentioned the window of 2016-2019, and I figured they would try to use a standardized cell on all models for maximum cost effectiveness.
Will LFP work in the original roadster replacement, or would the car be too slow with LFP? As a side note, I am still daily driving my 2011 Volt which I bought new in March 2011. It’s lost a little range and is “cranky” when cold soaked. But It’s still driving after 12 years on the original battery. I plan on getting 14-15 years on the original battery. The Volt used prismatic cells with NMC chemistry.
The difficulty with first gen Roadster is the electronics are out of production since 2008, and radical cell changes are limited by geometry constraints, performance differences, and no one in Tesla or the aftermarket space can carve ROI by reinvesting in a new design. There are many better cell technologies after 15 years, but integrating them is too costly for just under 2000 owners.
Great video!
Well, I hope my 18 Model 3’s battery holds up better than the 2016 Roadster/S does 😅
That is certainly what came to my mind. Just try not to hit the mileage limit on the warranty before the 8 year mark!
Tesla keeps changing the battery chemistries and design so the answer is unknown. It is just called Li battery.
Nickel, a major component of the EV batteries, is found
just below the topsoil in the Rainforests of Indonesia
and the Philippines. As a result, the nickel is extracted
using horizontal surface mining that results in extensive
environmental degradation: deforestation and removal
of the top layer of soil.
how could you talk about the issue for 9 minutes and not mention the brand of the 3.2AH 18650 Cell? Are they Panasonic also?
So far no issues on my R80 pack. It has about $5k miles on it
Is it a 2016 or 2021 version?
@@grubermotorcompany I assume it’s a 2016. I’ve owned the car about four years and it was in it when I purchased it
Who manufactured the replacement cells? If it's Panasonic I would be concerned.
All indications are the original Panasonic cells were not used due to a very high MOQ, so a Korean company, LG, was sourced.
when do we expect model S end of life to happen? I have a 2013 model s want to be cognizant of it :)
The original Model S batteries are going on 11 years now and for the most part still performing minus some range loss as they age which is expected. Cell chemistries keep evolving and we do not know precisely what variation was used in the Model S.
I have a 15 Model S with the 85kw battery. It's going strong with minimal loss. Seems to be about 90% of original range.
The architecture of the battery is all wrong. Notice how it's not flat, which leads to heat buildup.
32k for battery replacement? Thats alot.
We ran the numbers. Based pn cell count (6831 per pack), manual labor to connect and install that many (no robotics on this one), it looks like they are generously offering this replacement under cost.
Easy fix. Just put a Honda K20 engine and call it a day.
Please let us know what you and Tesla come up with.
A replacement pack with Sodium batteries.
We will have much more information as this issue evolves.
A large sac of potatoes.
@@grubermotorcompany Isnt this considered under warranty? 8yr/100k mandated by law?
@@Cjdergrosse The warranty period for this battery pack was 5 years.
Manufacturer warranty laws are governed by the UCC, the Magnuson-Moss Warranty Act, and the FTC rules. Itcovers retailers' express or implied guarantees of a product's quality and/or reliability. The seller is promising that the product will perform as described.
The warranty period is not mandated and is up the the mfg. The only enforceability is honoring warranty within the period stated, and if it meets use conditions set by the mfg.
EVs are still deeply unappealing and potentially a deathtrap for us folks living in the frozen north. I've got my eyes peeled for the first person to freeze to death at a charging station due to their car failing to charge.
