Battery management question

[mcm209]

I have a 250 mile round trip that I take twice per week that requires either a 100% charge or a stop at a supercharger to complete. Would it be better for my Model Y battery to charge to 100% twice a week or Supercharge a few minutes twice a week? Any help is appreciated.

AFAIK, 100% charge is a problem ONLY if it's left parked. For pure convenience, I'd charge to 100% and drive it.

No option to charge a bit at your destination, even for an hour or two? Then you could not charge to 100% and still not supercharge, just a thought.

Second that... if you stop for any significant amount of time at your destination, a level 2 charger might make a lot of sense. Even 120V charging might be enough depending on your specific case, depending on how long you are stopped.

Anyone care to weigh in on the twice-a-week 100% home charge, using the car immediately after?

My 0.02c : is it the best you can do to the battery? Probably not. But the decision isn't that. It is great to use a supercharger regularly? Probably not. The best is to stay between 40-50% all the time and never use your car I'm serious... you can read about ideal conditions but at the end of the day this is a car, and it's meant to be driven. You bought it to use it.
Even the decision to charge to 100% or use the supercharger would be more of a convenience thing for me than a battery degradation question. I would probably charge to 100%-ish but arrange so that this finishes right before I leave. The times I would forget to charge, I would use the supercharger, so I'm never stuck.

If it was my car and the drive I was making, I would definitely hit a supercharger for a short duration during the trip. If for no other reason than the extra buffer for traffic, wind, weather, unexpected detours, etc.... Just my opinion better to have some extra range, than trying to shove every last electron into the battery or trying to squeeze the battery to it's limits as well. Hit the supercharger, stretch your legs and go on about your trip with no worries.

You could slow down 10 MPH and gain nearly 20% additional range.

I'm not sure which way is worse for the battery, but if I was faced with this choice I'd probably just rotate between charging to 100% and using super charger every other trip.

Here is the thing. You can inconvenience yourself and stop at a supercharger, that way you can preserve the battery for whoever buys the car from you (and you’ll pay more versus charging at home).

I say charge it at home 100% and enjoy the car without having to worry about where to stop and charge.

My vote is rotate between each option.

• Schedule the 100% charge to end at the time of your departure.
• Charge to 80% and hit up a SC go full speed.
• Charge to 90% and use the included 110v at your destination and reduce your speed.

As per previous comments, I'm sure you'll be fine whichever option you chose - I personally would mix it up from time to time and always ensure you have a buffer. For instance, I10 between Tucson and Phoenix get's shut down by accidents way too frequently and I wouldn't want to be stuck on the road for a while hoping my AC doesn't drain the battery while I'm sitting in 110 degree heat. I think you'll find after a while people obsess way too much about charging and range as a whole but it's part of finding your comfort level with an EV vs ICE. Enjoy!
