How often do you charge your EV to 100%? Once a month (as suggested by the manual)? or every two months ? or every 6 months ?

[Acpantera]

My wife charges her GV60 once a week at EA for exactly 30 min(free!), the battery is usually at about 40% +/- 10% before charging and usually 80 to 90% after. Every other week we top it off with the home charger @7.5kwh. I really think people over think this stuff, I don't see how you can go wrong with following the Owners manual, after all they(Hyundai) wrote the book on the vehicle they engineered and produced. Following the manual will aid your case if in the future you have a warranty claim on the battery, and that warranty is the longest lasting in the bizz.

We don't have our GV60 yet; maybe by month end. I'm curious if the GV60 has PNC (plug and charge) automatically with EA or do you have to use the app or ???

It's a pain sometimes as you have yo use the App. If you try EVGO (not free of course), they have the GV60 set up as plug and play. I just opened an account with EVFO but have not actually tried it yet as I have been home charging. I actually prefer home charging. I know we get 3 years of EA free but it has been a hassle for me driving too/from and using the EV stations in my area.

I too just home charge. The closest EA station is nearly 30 miles away so that doesn't make sense just to get free charging. One time I did charge at an EA station on a road trip and I am not sure how I get it to start charging but I did and it worked.

We're pretty lucky, EA is just 4 miles away in a Wally World parking lot. 30 minutes is about all the time we need in that store....couldn't stay any longer if I tried, place freaks me out, lol.

The closest is about four miles away for me also. But it isn't worth the hassle to me, not to mention that fast charging is not great for the batteries, vs. simply plugging in at home.

To each his own I guess, but I highly doubt DC charging once or twice a week is going to make any difference in battery life. If money is no object, good for you, I personally like to take advantage of the free energy. As for the hassle? Not really a problem for us, we always need something at the store anyway, pretty easy and painless process. Plug in, swipe the app, shop, end charge, hang cord, and drive away. The car is driven about 200 miles a week.

I would absolutely love to take advantage of the free charging but, I live in a charging wasteland.

If I only use my Level 2 charger, can I charge to 100% all the time?

Personally, I think it is still better to charge it to 80% unless you have a long trip ahead and needs full battery range. The reason is base on "Batteryuniversity.com" research, it is better for the battery if you keep the battery not fully charged to 100%, and you have a lot more "charge and discharge" cycles if you keep it between 30% to 70%. You can check out that web site, it discuss a lot of different type of battery and you just need to check on the Lithium-ion section.

Thank you for this information, a lot to learn!

These batteries aren't any different than cellphone batteries, don't overthink this stuff. Charge as needed, I think what they meant to not charge 100% every single time you plug it in plus I read somewhere the degrading factor is like 5-10% after 10 years not worth driving yourself crazy over it

 

[daveskee]

Don't forget too that there is a buffer built into the GV60 so even if you charge to 100%, you are only using about 95% of the battery capacity (74 kWh useable vs 77.4 kWh capacity). Never really charges to a full 100%. I'd be more concerned with constant DC fast charging, which is more taxing on the battery pack than Level2 charging. IMHO.

 

[edwardlican]

I charge it to 100% once every 3-4 months. Usually, I will plan to charge it up to 100% if I have a longer trip I need to go the next day and then use the charger to caluclate when I am going to leave and then charge the car to 100% just before I take off.

Despite all this written advice regarding this issue of no more than 80%, charging an EV to 100% using an AC level 1 or level 2 charger will result in negligible battery degradation. Fast DC chargers create a lot of heat and that creates slightly more degradation but nothing significant either. It’s why manufacturers have to give an 8 year warranty on EV batteries remaining above 70% of original capacity after 8 years.
In California they have to give a 10 year warranty.
This is akin to the days when oil changes were supposed to happen every 3,000 miles. Another piece of marketing bs put out by the oil companies.
I don’t believe that the majority of EV owners will keep their cars for 8 years or longer and certainly leased cars will be turned in much earlier.
Trying to preserve the battery capacity in your new EV is like not making love to your significant other so they will be pristine for the next guy/gal/other.
I charge to 100% when I need it, without thinking at all about the potential degradation. It’s really never going to be an issue for me because I don’t keep daily use cars beyond the manufacturers warranty.

If manufacturer are so concerned with battery degration why not just have a higher buffer capacity so charging to 100% won't be a issue. Unless they just pushing charging ethics to get people going at the charging station, it makes perfect sense since 80% is more than likely all you need to get to the your next stop. Constantly charging DC or letting your battery completely die it's more of a concern.

You are my hero! I decided, after a few months of ownership, to charge to every time with my home charger and drive it. It has made me so happy.

I think it's a fine line between using the battery pack to it's fullest capacity (squeezing as much mileage out of our relatively small battery packs) and best practice for battery longevity.

I think you've go it right, here. Charge to 100% when you need it and don't sweat it.

The subtext to this might be 'don't keep your battery above 80% when it's not needed.' From what I've read, the concern is time spent at (not charging to) high SOC , so if someone is charging to 100% and then heading out on a trip, little time will be spent there, and therefore nothing to worry about.
