If anyone's interested, here's a video of how the I-Pace concept's thermal management system works. Heating the cabin with the motor would increase the car's range and I think Tesla is doing something similar. Makes sense especially for those in colder climates.

Tesla does use this same system and other EVs use something called a heat pump that ultimately does utilize a bit of power or they'll use resistive heating which is essentially something like a hair dryer or a toaster operates.

They even say the I-Pace can gain up to 50km more range between charges. That would be vital in the wintertime for those living in colder climates because blasting the heat will drain the battery pretty quickly. Aside from Tesla, nobody else was using this system and Jaguar will be the second.

I do wonder what the system is used for in the summer.

 

[I-Sprint]

Didn't think about that. In the summer time, heat is your enemy so you'll need it all to escape as much as you can from both the battery and cabin for comfort reasons. I wonder if there's a different level of tech for air condition that it uses or if it's just a standard electric ac compressor.

 

[PlaidBeaver]

They didn't really go beyond the heat pump and how it cools the car, only how it heats the cabin. The intricacies of the system would probably baffle me anyways. Maybe looking at Tesla's systems would give you an idea.

 

[I-Sprint]

Considering this system is something like the Teslas, I think you're right. Even just looking at Tesla systems to see how they operate could give us a core general idea of what the Jaguar system will be like. That being said, this information doesn't really do much for us in the real world of things, but it is cool and gives us more knowledge on new systems

PinkJaguar : Heat pumps can work both ways, so this is potentially good for the summer too. They are more efficient as they just move energy from one place to another, rather than be the source of the energy.

 

[PinkJaguar]

I found a very basic explanation of how the heat pump works in the summer, with the heat pump moving heat from inside to outside. I guess that means air is drawn from the cabin and cycled outside?

 

[I-Sprint]

So it's essentially just exhausted out? But where would the cool air come from in that case?

 

[PlaidBeaver]

Probably use electricity from the battery to cool down the outside air in case of AC, can't imagine a process where the thermal management system can cool air by itself.

 

[Dec]

PinkJag, think about how your freezer works, no air is transferred from the inside to the outside, yet it gets cold. The energy in the freezer is used to convert a liquid into a gas that is then compressed back into a liquid, which heats it, the heat from the compression is radiated into you kitchen/garage/utility room. The liquid/gas is in a sealed unit. Energy is moved from one place to another either cooling or heating, the mechanism in a heat/air pump may be slightly different but moving of energy, heat, from one place to another is, apparently, more efficient than generating heat.

 

[I-Sprint]

I think it's also worth mentioning and talking about that this thermal management system can add up to 30 miles or 50km of range to your I-Pace which is pretty darn cool. Think this was mentioned in the video but for those that didn't watch it and are just jumping into the conversation

 

[PlaidBeaver]

That's in ideal situations, so I can see it reducing the amount of battery drainage in the winter when you need to heat up the I-Pace. Instead of drawing those 30 miles from the battery, it's heat pump from the motor.

 

[PinkJaguar]

May not seem like much, but add in regenerative braking and the thermal management system will seem more relevant to hypermilling your I-Pace.

 

[I-Sprint]

The thing with EVs is all of these little things we take for granted in ICE vehicles actually matters and contributes a lot to the range that you're getting. Proper driving etiquette is crucial to the range you receive and depending on how far your commutes are, getting into an EV is really going to alter your driving habits.

 

[PinkJaguar]

With how much low end torque the I-Pace will have, we won't need to be as heavy footed when moving from a dead stop compared to an ICE vehicle, which should save us a bit of charge. For short trips, driving habits don't need to change overly much since you most likely won't run out of charge. But trip driving while hypermilling will need some getting used to.

 

[J.XAU]

I hope we get some semi-autonomous cruise control system since that will help a lot in the type of driving that drains the most range, city driving. Better for those of us with a heavy foot! They were already reported doing developments in that area.
