Heat Pumps Improve EV Range in Cold Weather

I don't think this has been discussed before, and if so, maybe there's some new info here.

How is an EV goinng to drag around a heat pump? A Rube Goldberg design for sure.

I suspect that you're trying to be funny, but just in case you've posted because you're unfamiliar with the technology, here's an article with pictures to help you understand the setup. Tesla's been using heat pumps for several years now. I've posted a pic just to make it a bit easier for you to see that Mr. Goldberg's expertise is sorely lacking here.

All Tesla Vehicles Now Have Efficiency-Boosting Heat Pump

After giving the refreshed Model S and Model X a heat pump, Tesla gave all its vehicles this component to improve their energy efficiency on cold days.

What do you think an AC compressor is?

I wonder how effective the heat pumps are when it's extremely cold though

EVs in the winter.



ICE vehicles in the winter.

Proves my point. I assume that device has lots of extra seals, a pump, valves, plastic bits, an aluminum heat exchanger and fluid.

Must be a Goldberg design for sure. What could go wrong with that?

Literally all the same parts vehicle air conditioning systems have had for nearly a century.

Really good. I have heat in the car in at least half the time as my GTI.

Assume? You know the adage about "assume" right?

Huge advantage to heat/cool the car while charging.

Tesla's heat pump system is unlike a home heat pump. The idea is rather interesting, and it can take heat from the motor and battery pack.

My Prius Prime has this getup. So in ten years when all the r1234yf leaks out I will not only have no AC, but no heat as well.

It really is an equalizer. It's for keeping the battery and motors at optimum temperature, both raising and lowering temperatures and heating the cabin. Sure it does eat some range but it works very well at its purpose and on a cold day in a pinch I'd rather be in the Tesla than the VW.

Actually the opposite.

It's a master class in thermal packaging and efficiency - not the heat pump part per se, but the octovalve assembly that proportions and directs it.

This is the kind of thinking you just dont see at the legacy automakers as a result mainly of their compartmentalizations.

Sandy munro has a few vids on it and why it's so clever, and compares everything to it as a reference to what can be achieved.

Thank you for that eye opening video. The complexity and probable cost to maintain these systems will be mind numbing. Thirty-two coolant hoses? If I ever needed a nudge to go retro in my vehicle choices this provided it. If the average Joe wants to drive a four wheeled version of this, go for it.

I'm buggin' out.

How many hoses do you think are under the hood of your gas car? I can assure you it's a similar amount.

Yes, but does the system have resistive heating aswell for when it's too cold for the heat pump to be effective? I'm sure it does and that explains it working really good. Except range will suffer just as the battery isn't in any mood to play.

“The system conducts thermodynamic arbitrage from finite source thermodynamic sources and has the ability to augment those finite sources “

Tesla Model Y Heat Pump Details Infrequently Discussed By The Media

Tesla’s new system “boosts” the heat pump to give it better efficiency than regular heat pump systems and uses unique methods for heating below -10C.
