Ick...you're forcing heated coolant through the radiator?

 

[remy_martian]

No

I'm observing that the heat energy taken from your HV battery to run the coolant heater, in your diagram, has to go through the radiator when it's January in Chippewa Falls.

It's your loop design. I'm just providing the feedback you requested under #1.

Another observation: you're either heating the battery or the cabin with heat produced by the charger when charging or the inverter when running hard...

 

[remy_martian]

You may need a flow control valve at/in the splitter after the water pump...

If you have big bucks for a servovalve, they can

 

[remy_martian]

Those appear to be on/off "switching" valves, solenoids, not servovalves.

 

[remy_martian]

I didn't say you needed proportional...you inferred you had it.

I merely stated you need to adjust the flow (is this why you used "flow" charts? 😂) between the two parallel paths or the lower flow impedance path may hog most of the coolant flow when you don't want it to.

Looks like that valve may have a motor in it. Any idea how it works, the connection modes, & the pinout?

 

[remy_martian]

Looks like a potentiometer. So there should be a feedback pin, and then a way to forward/reverse the motor.

I believe the Tesla valves also use a "feedback" pin on their connector. Being "5 years ahead of everybody in technology" means an old Prius wouldn't have done the same thing 😂

No doubt, Brian would know.

It's a very useful resource.

Any plans to do Model Y on your blogpost?
