This is an excellent illustration of why a computer chip shortage will affect car delivery times! Great video. I'm always shocked how large HV capacitors get. Crazy.
Another fine video brought to you by "Speedkar99". Thank you. Surprises me all those electronic parts with stand the environment. Finally saw a video on a Mazda plant building cars from casting to machining. Transmission building & how they use rotary engine for the gas engine portion. I swear I could hear your voice except no voice. Low music & written explanation. Being an I/E Journeyman I can truly appreciate the PLC programming that goes into making those robotic welders & other automated equipment function. PM's & calibrations, wow. Lots of visual & hands on QC goes on still. Amazing
This hybrid controller is so similar to Toyota. Both are very robust looking for electronics. Both are very obviously designed with a priority on reliability and longevity. I hope the Fusion hybrid transmission is next. It will be interesting to see how Ford build theirs compared to Toyota.
Great content, as usual. You've just shown me something really scary. What I've just seen is $$$ repairs. I wonder what tolerances they used. Usually, in automotive, we're using elements, like caps, with operational limits between -50 - 105°C and I wonder what's the upper temperature limit this assembly reaches. The higher the temperature, the shorter the longevity of the elements. Usually, the lifespan of elements like capacitors is up to 5 years. As for semiconductors - it depends heavily on the temperature. And now I wonder: what happens after these 5 years. Capacitors simply can't last longer. What's the cost of the unit you've just disassembled. Power electronics never last long because of the very nature of semiconductors: they lose their properties in functions both of time and operational temperature. The question is what tolerances they used. What's also common in automotive is gradually shrinking these tolerances to absolute minimums. Each iteration will last shorter. Add to this the cost of wearing motors - isolating enamel has also a short lifespan, also heavily dependent on heat - and we have a disaster. And eco-ignorants will keep saying that "EVs have very few moving parts" - so what, if they heavily rely on complex electronics! Imagine now: one, cold solder joint... This thing vibrates because it's a moving vehicle! That's just terrifying. It's not "green"/"eco" whatsoever. And what about recycling all that crap? There's no single facility recycling this and there's not even one company recycling Li-Ion batteries. Mind boggles.
I remember the first ford escape hybrid becoming one of the most reliable vehicles you could buy from that time period. Knowing how ford usually likes to build their cars, I consider that to be entirely by accident
I’ve had spirited discussions about whether when it says 3 phase does that mean the motors are AC. We concluded they are in fact three pole DC motors. With a speed controller. A three phase AC motor is a specific thing and if you want to control its speed that is another matter. You mostly find that in industrial speed controllers. What do you think?
They call it DC, but in principle it is an AC motor. A DC supply imitating three phase by switching on and off. They call the motor "brushless DC" But I think that's more for engineers to feel smart about minute differences. A BLDC and an AC motor will both have three windings (in three phase; we aren't going to esoterics in this comment like six and nine phase) The motors are technically referred to as "BLDC AC motors" or "ECM's" electronic commutation motor" A "speed controller" regulates voltage, for the most part.
@ Yes! Brushless DC was what we settled on and I’m not an engineer but my brother and the men I was discussing this with were. Thanks for the breakdown 💯
@@YourFriendlyHoodVampire there's a distinct difference...brushless DC is made for trapezoidal waveform, synchronous AC a sine. Trying to run on the wrong type results in (much) lower efficiency + will probably make the controller...unhappy...
@ you're over thinking this; A winding is a winding. A "trapezoidal wave form" has no bearing on efficiency. In fact, a trapezoidal waveform is AC, so what now? BLDC controllers are PWM and output AC.... If you want efficiency then you focus more on bearing quality, Permanent magnet quality, etc. Add more pole pairs, blablablabla No matter what, switching from DC to AC will make efficiency pointless; You will always lose efficiency from that process.
Getting to the bare copper pieces requires a lot of time consuming and tedious disassembly tho, unless you have a big shredder to break the boxes to bits, not sure it is worth the work needed.
I still so surprise that they are using thermal paste that can dry out and lead to failure. You would think that for the price of these vehicles they aren't using some kind of phase change material instead.
Nah, I owned one for a few years. It works great. Fewer moving parts (see the Prius transmission teardown; Ford’s is conceptually identical). No alternator, no starter, and no drive belts (water pump, AC, and power steering are electric). Never a single issue with the drivetrain or electronics, good performance with 188 HP, and averaged 40 MPG even though I get on the gas like a meathead most of the time (the “secret” to good MPG in a hybrid is not tempering your acceleration, it’s refining your braking technique).
2:51 You wonder what is underneath there. Did we finally find something you did not know?

B E A U T I F U L video demonstration 😁👍 great job and great explanation
Shocking demonstration of electrical knowledge. Thank you sir!👍
I see what you did there
Merry Christmas buddy!
We are waiting for the reassembly video 😂

I don't think you understand what you're looking at.
It certainly isn't made for longevity.

no, they just licensed it all from japan.
AC compressor tear down, please.
awesome
Very interesting.

@@zxggwrt my point is, it's the same thing.

Can you slap the lid of the ECU more so I can understand that thats the ecu? *slaps hand on keyboard* thanks
Yeah I want to see the engine transmission tear down.
what could possibly go wrong with such a simple car.
I thought it was a big fancy toaster with computer chips
Look at those Cooper imagine scrapers doing after your hybrids system over catalytic converters.
Getting to the bare copper pieces requires a lot of time consuming and tedious disassembly tho, unless you have a big shredder to break the boxes to bits, not sure it is worth the work needed.
IGBT 🌈 hybrid wow
love me some electronics.
I think that was solid epoxy at 8:18, super hard to open lol
Notification Squad!🔥🔥🔥

How it works?......poorly!

Our Forester Hybrid has a worse mileage than our old Outback which was a regular car
Ford’s hybrid systems are actually very good. They’re almost identical to Toyotas.
@@Thegonagle so you prefer Ford
Can you be my mechaninc?
I can't imagin that Ford designed and thinked it over all by themselves. I think they had to pay Toyota to think for them.
Bulk $$$$$$$$$ - Life span?????????? Use your brothers gloves!
