Battery expert opinion
Any battery experts out there ?
What would be the optimal charging schedule for the EQS battery for daily (non long distance) use.
If you are going long distance than it is clearly 10%-90%. Pending chargers availability on the road it may go 0%-100% (albeit not recommended). So this is a no brainer.
What would one do in a daily routine though? I personally use about 10% of the battery in my daily routine and I charge at night to 80% so I keep it in 70% - 80% range.
Not sure if this is the best for the battery. I read all kinds of tales online. Some saying that keeping it at 40%-50% range is better. Some say that battery has to be drained to 0% from time to time.
Is there an expert out there to shed some light on the issue?

I am guessing fast available chargers are being installed first in areas with a heavy concentration of EV’s first and will later on be better available to other more remote areas. It is a decision based on eventual profit. If I remember correctly California has the largest concentration of EV’s at this point so it makes sense to have a large number of chargers there. In the Houston, Texas metropolitan area of 8 million folks there are only 2 non Tesla Level 3 chargers inside the Loop 610 area listed on Electrify America. A literal charging desert for EV owners. Plenty of Level 2 but……
There are 5 Bucees travel stations in the Houston area. These average over 100 gasoline pumps per store and they are each now installing 20-25 level 3 chargers at each store. Problem for us is they are all Tesla…..

You do not have to charge every day. I don't charge it till it's around 40 percent or so unless I know I have a trip the next day. That is usually about once every five days or so for me. The only reason I charge at that level is to make the charging rate shorter. In summer I was charging to 80 now Im doing 90% to compensate for shorter cold weather range. Since I live in an area with zero DC fast charger any trip outside of my general area I charge to 100%. In Wisconsin and MN most DC chargers are 50kw so I have to plan my routes to include 1 hr charging sessions when in non urban areas. Even Minneapolis there is a single EA fast charger and its in the suburbs (an absolutely stupid situation). Further west in the Dakotas it gets even worse with few chargers of any kind. After SD, there is an uncrossable charger desert unless you do an overnight stop at some level 2 charger (if you can find one). That is the dumbest situaition since a total of less than 10 stations through interstates in the Dakotas and Montana would fix that problem. There is a darned Walmart in every frigging town on this country!! Finding a strategic spot to cover the entire interstate system should be a no-brainer and could be done with just a few hundred stations in addition to the already existing ones. This is far from rocket science.

You will not make it unless you avoid Montana. There is a segment from Rapid city to Montana that is longer than the car can go. Furthermore, if you cross SD from MN you have to do a an 80 mile excursion off the highway to get to get to a 50KW charger in the middle of the state to reach Rapid City. Ive been waiting since I bought the car for a "doable" route from WI to Seattle. Not yet...... Unless you finda a campground or similar with a 220 charger to stay overnight.

I think after the beginning of the year you will see a boom of charger construction. The Biden infrastructure bill provides massive tax rebates starting Jan 1 so I'm sure companies have been waiting to start the projects.

With research into new solid state cells and/or silicone based (rather than graphite based) Li batteries, it's just going to get better and better for EVs. I believe most states will jump on board after the incentives start in January, and build a better charging grid. And, BTW, whatever happened to Musks promise to open his charger network to everyone? Too busy cancelling journalists Twitter accounts, perhaps?

Tesla already opened (allows) their supercharger network to charge CCS vehicles. Link It is up to the CCS owners and manufacturers to implement such charging by having a compatible connector and charging protocol. The issue was one of patent/technology rights. Tesla chargers opened to all vehicles in Europe several months ago where all EVs use the same connector..

Even if you had a adapter for a Tesla Super Charger their system would not recognize your EQS as a Tesla and would not initiate the charging process.

Tesla is again playing games on opening up their network. They were supposed to open it up by the end of the year and Biden even announced this when the infrastructure bill was passed. But Tesla has since decided that instead of opening up to CCS they want a new standard (NACS) that they created to be the standard plug for all EVs. And they are making this available to all EV manufacturers but no one is buying in yet.
So bottom line, Tesla can say they have opened up, but the EV manufacturers are the ones that are not adopting the the new standard and in this game they continue to keep their network effectively proprietary. Frankly the Tesla charging network is really their only competitive advantage at this point and losing it will accelerate their loss of market share. In Europe I believe the EU has mandated CCS and so they have opened up in Europe.
Here is a great article.

Disappointing to say the least.

I've owned two Tesla S Models but traded for a EQS. One of the most disappointing things about the EQS and Electrify America chargers is the heavy, awkward charging cables at Electrify America. This needs to change and change now. The Tesla cables are much better, lighter to use.
Another thing that needs to change right now, not later, is backing into a charging spot. Brain dead way of doing things. Make the charging stations like the gasoline/diesel ones i.e. drive through so it does not matter which side of the vehicle the charging port is on. I'mm guessing the 'back in to charge' is being too darn cheap to buy the land required for drive through. And yes, I know i"d be the one paying for the drive through land.
EQS drive much better than a Tesla and is quieter on long.....well semi long trips seeing as how if you treat your battery right b/t 20 and 80 percent you can only make about 200 miles a charge if driven b/t 75-80 mph. I consistently get 30 miles per 10% of charge day or night fyi.

I'm not a politician, but if I can give some advice to Joe Biden, it would be to pass an amendment to the infrastructure bill before Jan 20th making CCS charging the standard just like they have done in Europe. It will be great for EV adoption, and will have the side benefit of "flipping the bird" to Elon who has not done him any favors and will be a thorn in his side for the next 2 yrs

The DOT has proposed in its rulemaking associated with the infrastructure bill that all DCFC has to have a minimum of 4x CCS Type 1 stations to qualify for subsidies. CCS Type 1 will be the defacto standard for the US.

Section 680.116(b) also proposes a minimum annual uptime requirement of greater than 97 percent for the charging ports.
I wonder if the folks at Electrify America have read this part and what exactly will be the repercussions for non compliance?

This is a good website if you want a view of what your state is doing with the NEVI funds in 2022 and 2023 and where the new infrastructure is going.

I live in the the west side of the metro Tampa area (Pinellas County). The only (CCS) DC fast charger in the metro area is about 1 to 2 hours away on the east side of the metro area (Hillsborough County). There are no current plans to add fast charging in the metro area. Until the fast charging infrastructure is improved, I don't see much of a market for EVs on the Florida Central West Coast.
