Really enjoying my car but hate charging to recommended 85%

[JRNJTAYCAN]

Long term battery management is just reality of the technology. FYI the same thing are recommended for charging phones as well (not to constantly charge them to 100% or leave it plugged in all the time) to preserve battery life longer.

Oh no then I am in trouble with my phone I plug in every night until morning!

So, very personal take on this, based on various things I read and asked around, I am not an expert myself, but:

- Apparently what hurts battery the most especially when charging to 100% is super fast charging.

- The taycan has a buffer on top of the 100% which means that you actually never charge to 100% yourself.

- It is better not to sit for a long time on a high percentage of charge.

- Charging slowly from low charge is best.

- Recent battery tech are not impacted as much by charging to 100%

So the way I do it myself, is that I charge to 100% and let it go down to around 25/30% through my daily usage. I do the charging at home and only have a 30A charger due to condo restrictions, so it charges pretty slowly, basically take the whole night.

Overall I do not charge too often that way and because it is slow charging it is not too bad.

Again this is my personal take, and I could definitely do 85% to 30% instead unless I do a long journey but I also find it annoying so I do this instead.

Also I don't drive my car that much overall, so I doubt I will hurt the battery too much before I buy another car anyway in like 5+ years or so.

So I would say do what you feel the most comfortable with, those battery are not THAT fragile either and even if you lose a couple additional % on your car lifetime because of it, it is not the end of the world?

I like your outlook and feedback thanks!

Porsche thanks you for guaranteeing their warranty will never be called upon . The next owner should kiss your feet .

True that!

What are your thoughts?

I always charge to 100%. The battery has a small buffer on top and twice as much at the bottom. I cannot be bothered to always plugging in the cable. I want to see how the car works in the long run, when you use it like an ICE. That means I only plug in when it is below 10% usually below 5%.

Prof. Fichtner Battery Research University Ulm said: "These modern cars with these batteries can charge full, no problem."

Result: Battery lost about 8% capacity after 2 years 2 months and 28600 km. I almost always charge at home with 11kW. The highest fast charging I have done is 120 kW. The battery ages anyway, no matter what you do.

I have always charged my Tesla to 100% and after 3 years it has shown “normal degradation”, do i really care how this battery performs in 5+ years when I don’t own it ?

Yep, that's what the research shows. I only charge to 100% over night, when I actually drive the car the next day. This is not more work, than an ICE, when you have to check and take a detour to fill it up.

So the way I do it myself, is that I charge to 100% and let it go down to around 25/30% through my daily usage. I do the charging at home and only have a 30A charger due to condo restrictions, so it charges pretty slowly, basically take the whole night.

I charged about 60 times in 2 years 2 month. Excluding the few longer trips, I usually charge once every 2 weeks. Convenient.

Also I don't drive my car that much overall, so I doubt I will hurt the battery too much before I buy another car anyway in like 5+ years or so.

IMHO, fussing over the battery is pointless. Even if you absolutely sure you keep the car for 20 years, time alone will age the battery to pretty much the same capacity, no matter if you charge to 85% or 100%.

So I have had my RWD pretty loaded up since March 2022. I just hit 4K miles so I do not drive it that much but I have to say that I hate one thing! The recommended 85% charging. I have only charged the car to 100% four times since owning it and that was only because I was going long distance. I love the range you get at 100% (on long trips 285-300 miles)but normally I charge to the recommended 85% (207-225 miles) which I hate. Every car I have ever owned (ICE) the dealer does not tell you not to fill your tank! So why do we spend over 100K for a car that we should not fill or charge to 100%? If I leased the car I would be charging to 100% but since I am a long term owner I follow the recommended charge.
I am just venting so please don't be a hater with any response.

If charging daily then the recommended charging level is 80%. For regular charging (eg weekly) then 85%.

Charging to 100% where intended use is within the same day is also fine eg for a longer journey.

Completely different here: I do not like charging to 100% cause of the missing recuperation on the breake pedal on the first few km...

Regular charging to 90% since more than two years now.

 

[backslashed]

It is not a problem to charge to 100%. It only affects the battery if the car stays parked like that. If you charge to 100% and immediately drive off it is fine, so try to plan it like that if you need the 100%

I understand the sentiment. When I refuel my ICE car, I am one of those people that fills it to the very top…there is something that is satisfying about that. I would ideally prefer to refuel my EV in the same way. Not because I need the range but because there is something more satisfying/complete about it. I will get used to 85% for sure but it’s not what I would prefer to do.

If you bought a ICE car and the manufacturer recommended hi-test gas but you used regular gas, you would see an effect in performance and possibility of damage to the engine.

No damage necessarily. It's ok to run 87 and over octane in most non-DI newer ICE vehicles. Any occurrence of knock and modern PCM/ECU will adjust accordingly. This does not apply to a 1985 Buick, etc...

From my wife's BMW manual: " If your vehicle requires an octane level of 93, using a lower-grade fuel can potentially cause knocking that can damage your engine. "

It must be a DI engine.

Daily driving set the limit to 80 or 85%, put a timer to charge to 100% at the time you plan to leave for long trips and DCFC when away as needed. The Taycan DC charges so fast, that I sometimes feel rushes to get back doing my shopping.

Main thing for health is keeping the battery away from extremes (high/low SOC and temperature) and it'll be in good shape. Just like our own bodies ?

I've read that sentiment enough times that I will never consider buying one of these pre-owned.
