Winter parking/driving

Hey all, had a couple questions.

I don’t have a garage, just a dedicated (uncovered) parking spot at my home in chicago. Is there any issue with having the EQS outside and potentially buried in snow for long periods during the winter here?

Also, how does it handle in the snow? Any of you guys have experience with that or not yet?

As long as you keep the battery at 50 to 80% while stored it will be fine. The 580 is fantastic in snow. Keep in mind its a very heavy car nad does not defy the laws of physics important considerations when braking and in curves. Finally awd is no replacent for good snow or all weather tires ( all weather with snowflake symbol not all season). If all you get is occasional light snow you can probably do with all seasons just fine.

whats the deal with needing to keep the battery at 50-80%?

oh and regarding tires, I thought all seasons would be fine. I didn’t realize there was a diff between “all weathers.” And no, we do not only get light snow here lol

Lithium-ion batteries self-discharge. How much depends on how long the time period is that you mentioned in your post and the temperature. Weeks? Months? Cold is very hard on batteries.

For battery health over long parking SOC levels of 25 to 50% would be better. Heat is bad for battery health, cold battery has reduced power output capability but no energy or battery life is lost. Once the battery warms up, full power is available and the energy too (minus the energy lost while heating up the battery and driving the car so far). 50% to 80% would be good for battery life and would provide the energy to warm up the EQS under a pile of show.

If the car is parked for a prolonged time (more than a week) you should keep the battery around 50 it will keep your 12 in good shape.

EV battery research indicates a 3% to 5% per month self discharge rate depending on the grade of each cell, i.e., A, A- or B. That can be a big loss in the northern US snow season of November thru March..

Wouldn't it be big loss in Florida too? Or are you assuming the OP to move to Florida for the winter? I thought the "long period" the OP mentioned would not mean the whole winter. Not sure if it was days or months, would be good to know.

The car would be parked outside in chicago all through winter.

Time wise, I was envisioning it being parked out there for a couple weeks (maybe as long as 3-4 weeks?) at a time without being driven or potentially recharged. Does that sound like an issue?

I also don’t have a charger at home so I was envisioning driving it to work and charging it at the parking garage there at somewhat random frequencies ranging from every 5 days or up to 30 days potentially.

I have our first baby being born in November so I don’t know how often I’m going to be driving it to work or driving it at all this winter. Cause I’m probably gonna be in the trenches for a few months coming up here!

If you are going to park it for weeks qithout using it, chrge it to 50 and check its state of charge every week or so. If it drops below 30 (which should take weeks) Recharge to 50 again. Essentially wash rinse and repeat. I would be more worried about rusting brakes and so on.
