Long story short, even if you don't have good battery hygiene practices, your EV battery is going to last pretty long. If you follow good practices, your battery will probably outlast your car. How you like them apples, ICE vehicles?

One of the points:

A) Charge to only 75-80% (unless you're going on a long trip), and plug it in every day when you get home from work (or at the end of the day).

I charge overnight using a 110v EVSE to 100%. My 10 y.o. car doesn’t even have the capability to program an 80% charge and I’m not going to set an alarm in the night to unplug it.

If on a long trip I will charge to 80% on the road.

And you still probably have good capacity on your EVSE.

On the Tesla, the charge setting is set it and forget it, you only do it once, easy peasy. Shows how they're every bit a software company as a hardware one. I can't imagine what it's like for other brands.

Almost went a whole day without an EV post.

Only charge your battery to 80%. Don't let it go below 20%. This means your range is 60% of the rating manufacturer's rating, Minus another 3% for driving at 70 mph, and another 4% when the temp is below 30 F. Don't forget to reserve 10% for going out of your way to find a working charger. This means for typical daily use, you can only expect a maximum of about 110 miles range.

Volts (plug in hybrid) can be charged to full as GM built in a top and bottom buffer. When the battery is showing full or empty it is really neither.

Does any one know if they engineered this into the Bolt also?

Thanks for posting this, I'm going to try and follow this advice for my model Y - charge to 75% and charge every day

Actually, when I first got the car about a year ago, I went through some of Tesla's educational Zooms (getting to know your Tesla, etc) and I remember in those presentations that they recommended plugging in every day and charging to 90%

At some point in the past year, my Tesla app stopped recommending a 90% charge limit and, instead, bumped it down to 80%

I bumped it back up to 90% and have been charging to that level but now will bump it down to 75% and see how it goes

In the past year I've noticed about a 10 mile drop in my range, hopefully following this advice will slow down that degradation

Thanks again

Actually a plug in hybrid is hopefully what you meant

I think that’s the only true alternative to a full on EV

You get all the benefits of short distance EV commutes like to work and back without the perceived range anxiety of true EVs

The Prius Prime, the PHEV version of the tried and true Prius, cost $5000 more than the Prius. It would take over 90k miles at 55 mpg to make up that difference even assuming zero cost to charge. Sorry, PHEVs make zero sense as long as the price differential exists.

I don't disagree - it's a complicated situation that needs to be tailored to each individual's use case scenario

At least when I was considering buying the Tesla last year vs other options, my research bore out that the only other option for me was a plug in hybrid

But, yes, you are correct I should have qualified my statement

I'll be the poster child for what not to do and we will see how long mine lasts. I charge to 100% every night and routinely go down to 10% or below. Also DC fast charge a good amount. Basically, everything they say you aren't supposed to do I'm doing on a regular basis. It is also cold here more often than it is hot, and it said the 80% thing doesn't matter if it is cold outside.

All of the data shows some lost capacity in Tesla batteries in the first 1-2 years, then stable for many years thereafter.

This is what happened to our first gen Model Y.

Hahahaha! I appreciated the good laugh.

My range on Texas roads, where we can often legally hit 80 mph, is well over 200 real miles on my Model Y charging at this 80% target to maximize battery life. I drive about 40 miles a day, so I charge it 2x/week at home.

When we've used our Teslas on road trips, we will sometimes push towards 90 or 100%. We typically drive for about 3 hours then stop for a break. The extended charging might reduce our total change down the road. So far, has not been a clear impact.

Finally, a number of the recent new battery chemistry (including the less expensive Tesla) actually recommends 100% charge.

Loved my Volt PHEV for this very reason. My son is happily using it for his daily commute, only using gas when driving to a different city.

Yeah this is why I was considering a plug in - my daily commute is a little under 40 miles roundtrip, so plugging in every night after work would've, hopefully, allowed me to rarely or never touch the gas engine except for extraordinary circumstances

In the end, though, I was swayed by the Tesla magic and went that route instead

I don't have an eV, but if I did, I'd probably charge to 100% just before use, but not 'store' it at 100% for more than overnight, if that.

On my eDevices, I use Optimize Charging to 85% and only go to 100% at the start of the day.

I almost never let them go below 50%, to keep the charge cycles low.

I'm concerned letting it rundown to 20% permanently loses some capacity, no matter how little, compared to keeping them above 50%.

All my Ryobi batteries are charged to three bars, and get charged to full if I'm going to use it.

I don't know if I'm right or wrong in this, and I'm not confident there's a definitive, final, accurate word on charging.

My daily commute is only ten miles, so I only charge my MYLR to 70% each night. That’s enough to get to work and back, go out for lunch, run some local errands and make the occasional client visit.

For days on which I know I will be traveling farther and need more charge, I charge to 100%. I have charging set to begin at 2 AM, so the fully-charged battery sits for only a short period of time before my departure. It doesn’t take long for charge level to drop below 80% from there.



It is what it is.

Could that be due to worn tires, or new tires that are not quite as LLR?
I opted for a more aggressive tread last year when I had 50,000 on my original tires.
Although still a quiet comfy ride the better winter traction made me lose about 10miles per charge.

Not sure, they only have about 11K miles on them, OEM tires

I just chalked it up to battery degradation, never considered it could be tires

Plan on getting them rotated in the next couple of weeks
