Preach sir! I love this channel, wayyyyyy better then anything on TV. Never knew I would be so into this stuff as a form of entertainment and learning. Just great to learn this stuff just to be able to form debate or have conversations.
Ben, Cory, Sandy and all your behind the scene staff is top notch. You all are relatable people and that is what makes these videos so popular. The focus is on the technical overview and details like an engineer or mechanic, and not on being slick and doing a business school type verbose but hollow presentation. Thank you to Monroe and Associates for educating and informing us. I eagerly look forward to your videos.
Thanks Cory, Ben, and team! Really insightful stuff. Engineering education is often overlooked, and having a channel that puts in the time and effort to explain things is extremely valuable. Hats off to you guys!

What is going on here... 4. I don't like it, too much stuff. Less stuff, more elegant. (or something to that effect) 5. That's actually nice, really nice (surprised tone) 6. This, this right here makes me happy! I think that sums it up. But seriously, This format works well. Each person playing to their strengths and explaining enough for the average person to be able to appreciate what's going on. Thank you
@@2hedz77 heat pumps are almost totally useless in warmer climates as they'd never be used, therefore, unnecessary weight. But you never knew where a car would end up, so you included it with every car anyway.
Correct the typical home heat pump starts loosing efficiency at about 40 degrees and stops working at about 25 degrees. So a home system will switch to the back up heat source somewhere in that range. Not sure about the temps that R1234yf will work at though.
I am not sure you made it clear for everybody why heat pumps are more efficient than resistors. Resistors convert electricity to heat at 100% efficiency. Heat pumps move a fluid and change its phase in different places (well detailed in the video). This change of phase (liquid/gas) allows heat to be moved from one place to another using Carnot's principles. Using the same quantity of electricity, you can move ~3 times more heat energy, making it about 300% efficient (compared to resistors that will convert electricity to heat, which requires energy conservation and limits efficiency to 100%).
Correct, but more simply, the plus 100% efficiency of heat pumps comes from "stealing" heat out of the ambient air. Any air that's above absolute zero has latent heat to be scavenged.
Good job, Cory & Ben! Only thing missing for me was a comment on relative efficiency of PTC vs Heat Pump. Heat pumps over their working range are 2x to 5x more efficient than PTC at putting heat where you need it. When it gets very cold and outside the range of the heat pump's design numbers then an external source of heat is needed. In a Tesla this is done by running the electric motors inefficiently causing them to heat up the liquid coolant flowing through them to supply the heat to the heat pump. TeslaBjorn's testing has show this is about 7kw of heating from the motors.
I think you could have explained the difference in "efficiency" since some will be confused that a PTC heater is essentially 100% efficient, but a heat pump can have a greater than 100% "efficiency" because it is refrigerating the outside air, moving heat from cold air to the warm coolant. I.e the heat moved is greater than the work done by the compressor.
Funny comment. These are brand new not driven vehicles so they are clean plus there are a lot more folks around doing the work. I used to work doing all sorts of things at a Mercedes dealer back in the 1973-74 period. There were many days that my clothing never got soiled so, yup no real amounts of grease and fluids that are such a mess. Still even though they stay clean. Remember they are not working on an ICE engine which by its nature is a mess. Appreciate your perspective
Nice clear explanation. Good educational content! Ford has a *lot* of engineering headroom to reduce energy consumption, reduce weight, and improve range on the Mach-E. I hope they/re listening.
But ask yourself "why"? Why should they be "watching" and "listening" at this point? They had since 2012 to watch Tesla produce engineering advances and still their first effort, the Mach-E, is basically the same ICE product Ford has been producing for the 100 years but now they slapped a battery under the floorboard. That's just lazy.
@@dzerres please gtfo with all that negativity, there is always room for improvement and there is always a beginning to something. Bmw for example was a pioneer with big castings and they built one of the world's largest carbon fiber factory to make cars lighter.
Considering the extreme demand for that vehicle i’ll be surprised if they don’t. They’ve already cut into 10% of Tesla‘s sales average time on a dealer slot is 5 to 6 days!
I have a Mach-e AWD Xr and I love it so far. 2500 miles. one 270 mile round trip from home and back with 14 miles still in tank. Charged to 235 with 16 amp charger over night. This in central Texas on a 90 degree day. Can’t see the stuff you guys are showing but it’s interesting. Thank you.
@@BigEightiesNewWave this was year ago. I haven’t brought gas for a year. I still have not charged at a DC charger. I’m 78yo and my 73 yo girl friend likes the Mach-e but she gets range anxiety. She needs her F250 pu to pull her grandkids horse trailer. Not a joke. So I do get to drive an ICE truck on occasions.
I love the detail and explanation. I always like the compare and contrast aspect that you did in the latter part of this video. I did miss Sandy’s “disdain” when he thinks something could be improved. No one could or should copy Sandy. Excellent video! PS Question: Tesla iterates and changes and improves manufacturing without waiting for a “model year change.” They certainly did in the early days of the Model 3. A good video or episode for your upcoming Plaid road trip might be meeting people with newer Mach-Es and see if they are iterating if the car is manufactured a few months after the one you are tearing down. At least on the parts, you can see with a flashlight 🔦 Thanks again.
I like this "format." Clear and concise explanations presented in an orderly manner. Just add Sandy for some occasional insights and comments and it'll be great. As always, interesting and informative. Keep it coming.
Great explanations and “hand off’s” to each other. The camera person behind the scenes does a great job zooming in to a component when the authors are speaking about it.
Partially true from what I understand it decreases insufficiency as the temperature gets colder, At a certain point traditional resistive heating is needed.
The heat pump not being able to extract heat at lower temperatures is only because of the working fuels like r1234yf - which do not do so well at those lower temperatures. You could use different types of fluids to work at lower temperatures - but those fluids range wouldn't work well for higher temperatures anymore.
I have an idea for you guys. You guys should name a "Munro Associate" EV of the year in terms of what your team thinks the best EV out there 👍. Hopefully you guys can talk about the Mach E autonomous hardware like cameras and it's chip.
I can never look at vehicles the same way, and that is fantastic. I love Sandy but it has been good to hear from some of the other team members. I should have studied engineering.
The heatpump when heating, basically an air conditioner in reverse, it cools on the condensing side so much it can freeze and fail. I've seen it happen in domestic heatpump systems. The gaseous phase can only extract a certain ammount of heat from the outer air when vaporising and you would need an electric heater to supplement it below 5ºC-10ºC, roughly.
I am in the midst of having to replace the consensor on my Mach-E due to a puncture. This really helped me understand the itemized estimate. (I had mud flap flipped up into it while doing 75MPH and it took out over the active cooling shutters and front-facing radar sensor too.)
The channel is getting more entertaining. More cast, more professionals giving insight and now cutscenes on who and how they take apart and handle the vehicle parts. Keep it up
Very good show guys putting it into layman's terms. As a fridge tech I understand the benefits and something that I try to teach the new techs coming through. Thank you
@@NewCastleIndiana I hope you’re joking. This channel still uses iPhones for filming because they’re really great at it. No need for an expensive camera, if you can just use your phone.

Interesting to learn how the cooling and heating systems work in the Mustang Mach-E. I'm not an engineer, but I can add some important observations as the owner of an MME in the south: That AC system cools down the inside on hot summer day real nice and quick, best AC in all the many cars I have owned. And in the winter, the heat is instantaneous and warm.
Best channel on YT by far. Professional content and presentation that is straight to the point, while also being informative and entertaining. You guys make my life as an EV enthusiast and investor much easier and better. Thanks again. My signed sticker is waiting for it's frame to hang on the wall
miles ahead, just miles and miles ahead of the Competition, ...there really is no Second Place. M&A is just awesome to share this with us. I am just thrilled to be able to peek over Your shoulders and watch you do the Science that You do.
The main reason for a heat pump is not to accommodate colder markets, it’s to boost efficiency. Heat pumps don’t tend to work very well in extreme cold. As temperatures drop the efficiency and ability of the heat pump to even make heat decreases.
Agree with the others! No need to apologies. It's great to see others and everyone over there seems to be super knowledgeable, so the content is great no matter what. Also, well done with improving the videos over time. The editing, audio, and just overall quality of the videos has improved and it shows.
The condensed gas is cooled to ambient in the condenser. When it’s evaporated into gas (in the evaporator) the temperature drops significantly. It’s this which gives the chilled air into the cabin. A home fridge-freezer works in the same way. Incidentally propane is cheap an excellent refrigerant and it has zero effect on the stratospheric ozone layer. Some might say it’s a fire risk but so is your gas lighter.
Great video. Very detailed and technical. One thing not mentioned is Tesla can run the motors slightly out of phase to generate heat for system as well. It counteracts some of the minimum temperature disadvantages in a heat pump design.
This is great. Clear explanations of how things work, and motivations behind various aspects of system design. Also, great to see an expanding cast of characters!
Waste Heat Engine (WHE) is a self-starting engine that operates in a low temperature range. This feature allows an engine to run on waste heat emanating from an external source, such as battery thermal system components.
I heard that the Tesla system also incorporates some resistors like the PTC does to get around heat pumps not working well in very cold environments due to heat exchange differentials with the outside. It would be great to hear to hear the high level overview of the Pros and Cons of heatpumps vs others. And it would be awesome to hear some mention of how Tesla could use their technology in a home HVAC system since Elon has said numerous times that he would love to do that, basically just "stacking them up". How well would just stacking up multiple units lilke in the car work in a home with central forced air?
Great description and explanation. What would put it over the top, would be an illustration of the cycle with an initial walk-through, and references to it along the way. I could follow this, as I'm aware of how the tech works, but for anyone new to the subject, it would be even more helpful. I loved the layout of the parts on the table, that in itself WAS kind of an illustration, albeit you had to really pay attention to not get lost. Thanks for all the nice videos Munro and Associates are producing, I think I have watched (and hit LIKE!) every single one!
All I would add is that you might have talked about the fact that the refrigeration cycle uses latent heat of vaporization, how that allows an air conditioner to move heat from a cooler environment to a warmer environment, AND how that makes heat pumps more efficient than resistive heaters. Also that a heat pump is really just an air conditioner that is cooling the outdoors. Still a great job and video.

Thank you for explaining it to me like I'm an idiot, because I am and totally admit to it.
He said pros & cons. What are the cons of a heat pump?
@@2hedz77 heat pumps are almost totally useless in warmer climates as they'd never be used, therefore, unnecessary weight.
But you never knew where a car would end up, so you included it with every car anyway.
Heat pumps are actually most efficient in mild climate. In fact in negative temperatures, resistance heating can be more efficient.
This is what confused me, atleast with residential heat pumps they are less efficient in cold climates and sometimes need an auxiliary heat source.
Correct the typical home heat pump starts loosing efficiency at about 40 degrees and stops working at about 25 degrees. So a home system will switch to the back up heat source somewhere in that range. Not sure about the temps that R1234yf will work at though.

The resistive heating is just 100% efficient not "close to 100%". There's nothing else the electricity turns into besides heat.

That's because it does not "generate" heat, it moves it from once place to another. That's why it's called a heat "pump".
@@TheJoeSwanon Thats correct, if outside temperature is too low the heat pumb will not work.
But in many climates the heat pump excels. My Kona has one and the PTC has never switched on.

I like seeing the development of new personalities. Hope it means we can see more content as it help splits time with everyone.
Great job team and keep up the good work! 💪☕️😊🚀🚀
Fascinating, detailed stuff! I especially love the comparisons to what other automakers use.
Good job you guys. Well handled. Good explanation and compact video. I assume mach-e would not be too great at -40 temps and long Finnish winter.
Why? Seems to me they have an actual heater.
5000 watts of almost instant heat. The battery won’t be happy waking up to -40, but the occupants will appreciate the instant heater.
That was enjoyable and informative. Excellent guys.
Very informative. Well done gentlemen!
I think it was a big mistake to not have heat pump as an option on the mach-e, gonna hurt sales in colder climates.
I understand they did it because they believed it was going to be too much of a weight penalty verse efficiency gains
I heard that the Tesla system also incorporates some resistors like the PTC does to get around heat pumps not working well in very cold environments due to heat exchange differentials with the outside. It would be great to hear to hear the high level overview of the Pros and Cons of heatpumps vs others. And it would be awesome to hear some mention of how Tesla could use their technology in a home HVAC system since Elon has said numerous times that he would love to do that, basically just "stacking them up".
How well would just stacking up multiple units lilke in the car work in a home with central forced air?
Good job guys. Thank You!
Good video! We want more.
Another great episode. Would be curious as to what sort of temperature difference between the gas going in and out of that radiator. Thanks.
Great description and explanation. What would put it over the top, would be an illustration of the cycle with an initial walk-through, and references to it along the way. I could follow this, as I'm aware of how the tech works, but for anyone new to the subject, it would be even more helpful. I loved the layout of the parts on the table, that in itself WAS kind of an illustration, albeit you had to really pay attention to not get lost.
Thanks for all the nice videos Munro and Associates are producing, I think I have watched (and hit LIKE!) every single one!
Here we go learning again... Love it! Just got my bumper sticker too.
Great job as always. Keep the Cory & Ben content coming!
Yes, they keep the presentation on track without the unnecessary reminiscing.
All I would add is that you might have talked about the fact that the refrigeration cycle uses latent heat of vaporization, how that allows an air conditioner to move heat from a cooler environment to a warmer environment, AND how that makes heat pumps more efficient than resistive heaters. Also that a heat pump is really just an air conditioner that is cooling the outdoors. Still a great job and video.
Great overview guys .thanks!
Thanks for watching!
