Great to see... 5 states are in! Hopefully not Francis Energy. LOL

Michigan Gov. Whitmer's EV charging plans expand to 5 Midwest states | Autoblog

Gov. Gretchen Whitmer's Lake Michigan EV Circuit expands to Illinois, Indiana, Minnesota and Wisconsin as the Regional Electric Vehicle Midwest Coalition.

I hope Wisconsin is smart enough to put some in Door County and the upper half of the state, and Michigan gets some into the UP. While it's nice they'll try to ring the Great Lakes, the general population of those states aren't exactly forward looking.

Has anyone ever tried to both charge and heat their cars in some brutal midwest weather or is this more of a nice weather day thing?

I asked that question on the FB's before I bought mine and found the answers to be correct by trial and error.

The heater itself pulls about 7.5KW at max input/output.

If you're plugged into L2 @ 32amps, that's about 7.6KW input, and the heater will be drawing 7.5KW.....IF the heater is actively trying the heat the cabin and working at full tilt....therefore, the battery will only get like .1KW of charge...if that much.
If the cabin is already warm and the heater is just 'maintaining' temperature, maybe the heater is only drawing 1KW....which would leave you with about 6.5KW left over to charge the battery.

Conversely, if you're plugged into L2 @ 10amps, that's about 2.4KW. While the heater is trying to warm up the cabin and working hard at it, the heater will still pull 7.5KW, which effectively is 5.1KW off the HV battery, 2.4KW from the charger. So while the cabin is warming up, you'll lose charge. When the cabin gets warmed up and the heater can settle down a bit, the battery will start charging again.

Yes back when we could charge overnight during Chicago winter the car was already full at 5am when i would tell it to precondition and I'd get into a 70 degree, defrosted car.

During pandemic date nights with the wife while it was cold out we sometimes park at a L2 station at a local park with the heat on and just talk.

I would love to have done that for my lunches at work this last winter but the nearest L2 charger is at a distance where I would need to charge for 40min just to break even on the mileage traveled to/from the charger back to work and that is without the heat on.


Also I am excited for this winter as I installed a 240v 16amp EVSE now so 3.8kw is available to precondition/heat the car in the garage rather than only 1.4kw. Due to the recall I have programed my car not to charge from 8pm - 6am. At 6am before I go to work my car has power available to top off up to 80% OR heat the cabin if I turn it on.

It is my understanding that the Bolt EV (all MYs) has a 2000 watt (2 kW) electric heater ((under-hood US passenger side). This could never draw 7.5 kW. Am I wrong in this?

I dont know the exact details but if I just start my 2020 Bolt LT and turn the heat on the usage will show 7+ kW usage rather than the 1kW-ish when it is off.

 

[GetOffYourGas]

My 2017 definitely pulls more than 7.5kW when preheating in the winter. I have seen it claim as much as 9kW! I lose a little charge from the battery, but it is worth it to have a toasty, defrosted car.

You're understanding is incorrect.
7500W, 7.5KW, .075MW, 7500000mW, 7500000000uW...

 

[skimask]

It'll pull more than 7.5KW in the winter...
Heater coils, battery heater, blower motor, radio, screens, wipers, etc...etc....etc.....et.c...c..e.t..t.c..c.e.e.t.t.c.c.c.c.e.e.t.t.t.c.... (too cold )

Opps, already said.

 

[XJ12]

You're understanding is incorrect.

@surgeonFWW is correct about the battery's separate resistive heater.

 

[skimask]

Ya, I know that.
I didn't indicate it wasn't.
What I indicated was the difference between 2KW and 7.5KW.

I'd say romantic but I don't say that stuff.

I must have been confusing this heater with the cabin air heater. I did what was suggested and cycled my heat (set at 85 degrees) off and on. Shur 'nuff, it was 7.5 kW! (That was with the fan blowing hard, also.) Thanks for correcting me.
