- Tesla Pyro Fuse Testing
If you have a blown fuse in your Tesla battery can you replace just the fuse or do you need a whole new assembly?
Looks to me like you only need the fuse 😎
Note: This is not advice, it's a record of my experimentation. Only mess with things like this if you are confident that:
A/ You are on the right of the Dunning-Kruger curve.
B/ You understand what you are doing.
Also only ever replace fuses once you have understood what caused them to blow in the first place. - Zábava
Better news! You don't even need a used good fuse to swap. The pyro fuse element can be bought easily & cheaply. Search for PSS-1 Battery Disconnect on e-Bay or wherever works best for you 😀
Same warnings as in description apply-make sure you understand why the fuse blew in the first place!
There is a predefined lifespan of the fuse. I guess about 8 years as all of a sudden, loads of 2016 Model S cars have got the warning on the dash to replace the fuse. It's not covered by the battery warranty apparently. Just quoted £287.28 to replace it but at least it will be replaced with the newer generation that doesn't have a battery and instead draws power from the traction battery through the fuse itself.
I am guessing the two large purple components are ultra-capacitors to fire the explosive charge.
Extra fault protection in case the system doesn't have the current to blow the fuse.
Love this
That protective film on the multimeter's display... how can you stand that being still on lol
And Lo, my 8 year old model S has a warning on the screen that the fuse must be replaced.
As the batteries go flat, the set-point reduces and it can cause a false trip. Or possibly no trip at all.
driver side in the front or rear?????
brilliant info. The two li-ion batteries, are they rechargeable? If so, any idea where it picks up gets its charge from?
No, they are not. I don't know if I mentioned it in the video bit this leads to a potentially dangerous situation in 20 years or so: The pyro fuse will not function and so in an over-current situation you will not be protected. Something to worry about in 2035 if we still have a livable climate....
Yes, I mention it here: czcams.com/video/k3BkMi91A4A/video.html
@@RaglansElectricBaboon bunch of ppl are getting warnings for those 2 little Li-Ion batteries on their Teslas now... seems these were pre-programmed into software for replacement after 8yrs?... Did u happen to measure the Voltage to see how good they were? Nice video btw :)
@@thebrain7693 makes sense that there's a warning pre programmed. I thought I measured the voltage in the video but if its not shown I don't recall it.
Why do people leave that plastic film over the screen of their multimeter? That creates so much glare
When its blown what functions it takes aways?
Max 200A from battery without this fuse. Most likely the 2x100A fuses will blow nearly immediately if you try to drive it again. However likely the pyro fuse in the main fusebox will blow too meaning the car will not allow you to try to drive.
