Tesla Model Y 4680 Penthouse Exposed and Pyro Fuse Explaination

Continuing with the tear down of the 4680 battery pack. Deeper dive into the penthouse revealing the components and layout. Pyro fuse explained

Thanks for covering the M Y penthouse. I was getting a “Cannot Charge” message even though it would super charge and home charge. Tesla said they replaced the penthouse cover and I had no idea what it was. I have no clue what was causing the message it was very intermittent. About 2 weeks average between notifications. Anyway you assuaged my curiosity and I will never ever be tempted to remove the penthouse cover.

Super cool to see inside the tesla penthouse!

Thank you for sharing. Right to repair is essential. Even it’s as little as a pyrofuse.

6:55 The metal ribs (ratchet) in the pyro-fuse are spark arrestors - they isolate and cool the HV spark when blown under load.

Excellent, thanks. Very good to learn

How difficult was it to remove the PCS? My car might need a new one. I am getting a pre charge failed boost error.

[@519Kustomz]

It wasn't that difficult. Do you have any other error codes, or just that one? I can try to help you diagnose it [e-mail]

Hey Dan. Really appreciate you sharing all this info on your channel. It's helping other custom car guys out more than you know. Did you make any videos about the galaxie conversion ?
Like you, I can't emphasize enough as to the potential danger lurking in these batteries for unskilled or untrained people. I guess we can't stop people poking around so the next best thing we can do is to warn them and maybe offer important safety information so that no one gets hurt. Ev conversions for old cars are going to boom just like retromods so it's better we share information than not in my opinion. Here's a great video that explains the purpose and importance of a pyro fuse and how they work. czcams.com/video/Kk4F8piyUmo/video.html

Hey Bill, thanks! Yeah the next few years are going to see a bunch of cool new innovative custom cars. I built the Galaxie before I decided to try a CZcams channel, but I am going to make a couple videos of it now that the weather is improving here.

The 2023 is totally different from this… no pyro in it again I guess

[@519Kustomz]

Just emailed you. Looks like back to the old design on yours. You need to remove the entire top cover to access the pyro fuse. BE CAREFUL!
