The man is an absolute goldmine of explanation power.
@TheCaphits
Thank you so much for producing these videos for people who do not attend Weber State. This is really high quality stuff and it's very enjoyable with you as a presenter!
@radman999
Your courses are superior to any institutional automotove training I have had in my career, including what is done at the manufacturer level. Your school and students are very lucky to have you, John.

I am a professor in France about automation and I think that i am far from a such level of quality of explanation. It is impossible to stop vidéo. Great job, thank You.
@HasbullahSyarah
Awesome! Thanks Professor!

Oh my god! I never thought I’d come across this guru talking about Teslas—especially after almost eight years. I remember watching one of your videos years ago about transmissions. Wow, amazing! God bless you. Sending prayers from Morocco.
@adityabhat295
This guy has god level skills of teaching. ...I take a bow to your teaching skills

I'm not a full time mechanic but I found this video absolutely riveting. Excellent tutor, you made everything so easy to follow; I never got lost once! This tutorial will be a fantastic asset to anyone (car mechanics / car technicians ) involved in the emerging electric car industry. Loved it, very well done sir, thank you.

I worked 42 years in industrial electronic controls with “Big Oil” and “Gas” companies. You are an excellent presenter of this technical information.
@omkarkamaji2412
Great Insights of High Voltage Architechture....you are awesome.. your passion towords explanation is amazing..great work
@JerryRigEverything
Awesome video!

I’m not even 5 minutes into this video and diggin it. He is an excellent teacher.

That pyro fuse is actually much more clever than you let on in your description. The pyro part is identical to the one used on the 12v battery, which is great at handling high current since it’s essentially a very low resistance bus bar, but it’s not at all rated for high voltage. It’s not an issue if it never opens because the voltage drop should always be close to zero. Unfortunately, if opened under load that component alone would experience the full 400V of the battery causing quick melting and a likely "thermal event”. To prevent that, the engineers added the 2 normal HV low amp ceramic fuses you see on either side of the pyro device in parallel. These fuses have a small but non-zero resistance, so they get almost none of the current in normal operation. Those fuses are however rated to fuse the full battery voltage without arc flash, so as the voltage rises during the pyro disconnect the current starts to flow through the fuses instead. Those fuses open the overall battery circuit once they get above 40A without any arc flash. Interesting enough this was just an intermediate design, and in the Model 3 they implemented a pyro fuse that could actually safely handle the full voltage without any of the extra components. I do love the ingenuity that went into this design, great example of a "what do we have lying around here that can solve this problem’?

Excellent teacher and extraordinary explanation of Tesla electric car. I learnt more from through this video. ❤ Thank u sir.
@JohnBrown-dz1yu
As someone who loves how it's made videos, tesla's, and being an EE this video is so interesting. Can't wait for the model 3 high power component examination.
@oisiaa
Wow, very detailed! This car started a revolution.
@stevewausa
"Let's see what's inside" my favorite part of your videos!
@mkmg76
Excellent video, thank you.
