Hyundai Kona 64 kWh 2020 model charging 

The charging is possibly the most important aspect of EV's. Love these comparisons :)

I too like these tech videos. My i3 manual recommends charging to 100% all the time and there is no easy way to limit it on my wall charger. Respect your comments on this though. Thanks.

I have a 2019 Kona in Florida (one of probably 10 in the state as the Kona Electric is not sold here) and I'm very pleased with the virtually not existing degradation on it.. I drove 34000 miles / 55000 km in my first 13 months of ownership and there is no sign of any degradation yet. The only difference that I noticed is that when I'm charging to 100%, the SoC BMS used to be 95.5% and now it is 96.5%, so it appears that I have lost 1% of my buffer in 34000 miles. I'd think that the high cobalt LG batteries in the Kona have extremely low degradation, probably also because of the conservative charging curve.. I don't charge to 100% frequently but I do DC fast charge at least once per week. All my cell voltages are within 0.02 volts and most of the time, all 98 cells are in sync. Since the BMS update, the charging curve of the Kona has changed.. It now charges at 58kw up to 76% or so and then drops to 36kw to 38kw and only at 78 to 79% it drops to 24kw. I do watch your charging videos! They are great! Keep them coming!

The charging performance of ID.3 58kWh is apparently very good. I saw a graph: 0-35% stays at 100kW 35-71% linear decrease 100kW -> 50kW 71-80% stays at 50kW

Thanks Uncle Bjorn, older konas are getting a similar software update. About 2 months driving till my next service, so looking forward to it (even thought it will not speed up the stop by much)

I like these videos! Charging is one the most exiting things in my opinion 👌

If Bjorn is taking about a subject it is important, some others talk the talk Bjorn talks the truth. Keep the videos coming information is power.

Bjorn, Great video again. I appreciate your knowledge on EV batteries and charging. Agreed with your views on charging and know it essentially up to your viewers but by repeating best practices you reach more and more people. Thanks

Great info, thanks! I find this kind of videos very interesting.

This type of info is very important i think it’s very informative for the owner

Hyundai recomends charge the battery to 100% once each month.. But not every day, great video Bjørn 😀

Very useful info as always, Bjørn 👍⚡

Roll V.T. Another great vlog charging science share. Big respect from U.K.

Thank you Björn

I watch all your videos

Bjorn, if you have time for roadtrip with Kona, please consider trying live data from OBD dongle feed to ABRP. It seems that 1000 km challenge will be faster in Kona / eNiro compared to classic Tesla MS 85 (D). Thank you for your job!

Hey I watch this keep going the more info out there the better

I heard James Cooke talk about very low charging speeds for his 85. That is some serious nerve...if around 50-60kW is now the max charging power. Those used to push almost 120kW at the low end! So....maybe a 1000km challenge in a classic 85?...the Millennium Falcon would be epic...if possible. Or maybe a Trondheim race is even better? Always love those charging videos...helps getting an idea how cars behave on a long ass trip.

Good as always Bjorn, on a separate charging note have you noticed reduced speeds on Superchargers like is being reported in other countries.

Yeah don't listen to yourself Bjørn! I've unsubcribed to all of my Netflix viaplay... You name it.. I've found these info videos more entertaining then the actual entertainment industry. And I do drive a Kona EV 2020. Did 3500+km in July on it. And charged it full every day... Shiiiieeett

I'm absolutly into those chargingvideos. Maybe separate your videos into different sections, so that those not so interested people can skip that section. I think there are many viewers enjoying those chargingscreens.

I only charge my Ioniq 28 to 100% if I specifically need it. On long trips I charge 94%, but that is because the range is basically short, as it is only a 28 kWh battery. On a daily basis, I only charge 80%. There is no setting option for this in the car, but with a homemade table it can be easily done.

One thing I wish Tesla would add is charge-rate limiting for DC charging. If, for example, charging at a supercharger station that's *not busy*, I could limit my rate to 59 kW. Still plenty but way easier on the cells. Also, they should account for actual rate of DC charge in the logs, as opposed to DC time vs AC time. Charging often on a 50 kW DC charger is a lot different to using a 250 kW supercharger.

in hong kong we have 37C ambient temperature in summer.

Hi Bjorn, There are a lot of "Car Scanners", which app-manufacturer? 0vZ? (wp_soft/Russia)

I REALLY want to see the Model S 85 derated charge speed too!

@Bjørn Nyland do you know what a full charge cost at a fast charger in norway with this car?

If you are buying a used EV there's no way of knowing how well the previous owner treated the battery so the manufacturers should take this into account. I would think that being careful with the battery only rewards you if you keep the car several years.

I watch only your short videos

Hi Bjørn, I'd like to bring up these videos about Kona regarding recent news in Korea and North America (not yet Europe) about a recall to update BMS due to what I start calling FireGate. One thing in this precise video is that you calculate the total battery to be ~70 kWh while the press in Korea these days mention just 3% buffer (66 at most). Maybe Korean and export versions were/are different? That could be the reason of 13/15 fires in Korea Thanks

I think those cars don't have the new software on them? I loaded my 2019 kona to 78% @49kw.

Can you please test charging curve of 39,2 kWh e-Soul on HPC charger and normal 50 kW charger and take the charging test between that and 64 kWh e-Soul on both?

Charge what you need (60%?) so you don't drop below 20%. And the slower, the better (not necessarily the most efficient).

Watched all the way.

100% on level 2 I think that ok but charging on fast charger (50kW+) maybe not everydays.

How do you setup car scanner to show the screen shown for ev ? Tried to setup the car scanner app but don’t see ev in fuel menu just fossils fuel . Anyone know if it supports Zoe ze50? Anyone link to ev version used here . Thanks . Another great video thanks

Poor Millennium Falcon. But there is still hope, maybe he got a new battery by now, the battery had a lot of km on it by the time the Falcon was sold. The Falcon deserves a 100 kWh battery pack from Elon. Got to reward the legendary cars. The P85+ from Hansjörg von Gemmingen - Hornberg has now 1.111.111,11Km on it and also deserves a 100kWh pack, or maybe the new 120kWh palladium ones. Bjørn i recommend you test the Falcon, we all want to see him again.

Question Is it healthy to charge to 100% with 7.4kW ac? I.e. overnight.

Anecdotally some owners of these Konas have got up to close to 500km range, so you don't need to charge up to anywhere near 100%.

Bjørn. Watch battery modules MO1 - MO4 values, not avg/min/max from BMS... If 1 of 4 modules reach 35 degC BMS will limit charging from 200A to 180A (75kW to 67kW). My enirodashboard is used on several Kona's and eNiro's and it's the same for Kona 19-20, eNiro 19-20. >35degC = 180A, 25 -35C 200A, 15-25C 150A limit, 5-15C ... ,

Please could someone tell me that OBD dongle which Bjon uses in his cars/Kona? My ODB does not work with the car scan app, he refers to.

Hei Bjorn,There are many apps in the name. Can anyone tell me which app it is?

Bjorn, I think you missed a (new?) step on the 2020 model at 38% it dropped from 75kW to 67kW

Bjorn I have a rendering of the upcoming Audi Q4 Etron, if you plan to do an upcoming ev preview video or something, just let me know. You're free to use it.

Just of track a bit but when are you testing id3 🤔👀

sir i watch all viedo

Can you make a link to the app for both Android and iPhone?

What is the name of that app that shows all that data?

My model 3 SR+ lives in the realms of 40% usually, waiting for available solar power. Suppose that's same as 50-60%, not worse?

Does the 2020 kona 39kw charge exactly the same speed as 2020 ioniq 38,3kw ?

Is recuperation reaches 120 kW as in 2020 eNiro? (Around 20% SOC)

Hey Bjorn, hows AC charging with the new model?

You forgot to mention whether 2020 Kona charges faster or slower vs older one.

I have Leafspy Pro. Can I use the same dongle?

for tha battery degradation i recently read a paper on it ... its not only the state of charge you charge your batter to, but also the depth of discharge that degrades the battery. something like you have around double the charging cycles if you only charge from 65-75% vs. 0-100% (and thats double the full cycles .. not double the charging cycles/micro cycles). if people are interested in it i'll leave a link to the paper -> ieeexplore.ieee.org/document/7488267 (but i suspect it will cost something to read if your not at a university)

That Hyundai can't be commercialized in Portugal with that model name.

8:28 I’m not 100% sure

I own a Kona Ev and the charging is rly bad lets be honest ...

Get me, I'm first

How quickly EV's go obsolete. This charging curve was reasonable in 2019. Compared to 2021/2022 cars it's utterly hopeless.
