Kia EV6 (E-GMP) FULL 0-100% Charge Curve Test & Analysis

Рет қаралды 760

Күн бұрын

After unintentionally running my EV6 down to zero, I test and analyze the entire charge curve profile from 0 to 100%. The same charge curve profile should also apply to other E-GMP EVs from Hyundai Motor Group including the Kia EV9, Hyundai Ioniq 5 & 6, and Genesis GV60. The only slight difference would be dependent on starting outside ambient temperature. During this test, the ambient temp was 32°C (90°C) and the sun was setting.
I did this test at the Electrify America Van Horn, Texas location and at the time the ABB Terra HP 350 kW charger was working correctly and outputting full power.

Super Kul vid. Loved it!

Thanks for watching! It was a bear to create, I had to type all the datapoints manually in Google Sheets. Then just a few days ago silly me noticed that Car Scanner had been logging all my drives for months! So I could have just pulled the logs from my phone. Hindsight is 20-20 I guess.

Enjoyed seeing you on the Coast to Coast EVs podcast today. Completely agree that this vehicle like all eGMP platform vehicles is a charging monster especially for the price. I have a Taycan and one of my better charging sessions was 10min in West Wendover, NV. 14-61% in 39.855kWh added, 239kW avg and 4.7%/min. Also had a 12-90% in 19min 65.721kWh added avg 208kW to 90%. This is a 2020 Taycan with 80k miles on it and 2/3 of charging was DCFC.

Thanks for checking me out from the podcast & that sounds awesome! So very little degradation in the Taycan? I think the 800-volt architecture is superior in many ways and especially in terms of less waste heat. My EV6 has a calculated 1% of degradation according to Car Scanner, but I can't see it in real life. I've charged it to 100% at least a total of 2 months straight in the last 13 months. I believe it's better to use the top part of the battery (100 to 20%) instead of the bottom half (80% to near 0%). The E-GMP's heavy thermal throttling at only 50°C I believe is helping preserve long term battery longevity. Tesla runs their battery cells hard to over 60°C.

Interesting comparison to a 1-100% I did in our Ioniq 5, thanks. It was 10-20C cooler than this and chose to stay in the 180kW region for most of the session, rather than going to town and dipping to cool.Only hit a max of 243A and had no BMS check at 80%. It's certainly a fun platform to test with sp much variation in power and battery management.

Wow that is so interesting. I wonder if the charger was limiting you? Only OBD2 data could back that up. But anyways, Branden Flasch told me E-GMP charging curves can vary a lot anyways. Basically almost every charge curve can be different day to day ⚡

Blazing fast!

⚡Agreed, no other EV in that price point even comes close. Road tripping my EV6 feels just as fast as a gas car. Of course, that's when the chargers work and can output the full 240 kW.

@newscoulomb3705 4 ай бұрын

Yup. The EV6 is a certified fast charging beast. After my experience driving one, I'm pretty sure I'd only ever use 150 kW chargers on trips. No need to even fret over access to 350 kW.

@ArtiePenguin1 4 ай бұрын

I do really like to see the 240 kW peak speed though. But charging at least at 175 kW doesn't seem to be that much slower. However, using paired CPE-250s at 120 kW max does seem to be twice as slow if I plug in below 70% SoC. A steady 180 kW is around where the time difference between seeing the full 240 kW peak speed is marginal.

@newscoulomb3705 4 ай бұрын

@@ArtiePenguin1 Yes. I try to align my charging speeds/times to my stops. The CPE 250 seems perfect for a meal stop with the E-GMP cars. A 12-minute bathroom stop on a 150 kW added something like 29 kWh, which was enough to keep driving another hour or so.

@ArtiePenguin1 4 ай бұрын

Yeah, makes sense. Wish I had that option here in New Mexico. The Socorro Plaza CPE-250 install can turn into a "nightmare" stop if another EV is charging. I actually saw another EV6 there and I left to do drone photos. Because if I plugged in then we'd both need to stay there twice as long. I guess low traffic volumes of all types is why the I-25 corridor south of Albuquerque only has Tesla Superchargers with a site concentration of more than 2 plugs. I really hope Francis Energy uses new SKSignet DCFCs for their NEVI awards in T or C, Socorro, Los Lunas, and Raton. Their Power Electronics 150 kW units have issues with E-GMP (and other 800-volt) EVs.

Thanks for this video! The EV6 really is impressive. Did the heat pump kick on before, or not until when, the thermal threshold was exceeded and the charging amperage was throttled? To what extent does cabin climate control impact battery cooling?

@ArtiePenguin1 4 ай бұрын

Hi, I have a RWD model so there is no heat pump, just a regular air conditioner. The air conditioner compressor kicked on about 3 minutes after charging started. It just wasn't able to cool the battery enough to prevent thermal throttling. If I had kept the cabin A/C button enabled, then the battery wouldn't have been cooled much and the thermal throttling would have been much worse. You need to disable the cabin A/C button in the car whenever you leave the car on and are charging over ~ 170 kW and it's hot outside. I'd say that overall the entire battery cooling package in the EV6 is under-specced for the hot Desert Southwest US. It is very clear they designed this car in Korea for largely urban/suburban driving in temperate climates. Hope this helps!

I don't think I've ever had mine thermal throttle. What was your ambient temperature?

@Crazypostman 4 ай бұрын

Interesting... Mine will hold the 305 amps until 57% and then I think it's 250 amps until 67% I can't remember the other ledges I'll have to look

@ArtiePenguin1 4 ай бұрын

You have to look at the battery data. But the starting ambient temp was 30°C (90°F) and the first thermal throttle is when the battery max temp hits 50°C (122°F).

World's first published on KZfaq with full OBD2 battery data from 0 to 100%

@raysreef2529 4 ай бұрын

Is it recommended to drive your vehicle to near 0% battery and bringing it to 100% will this degrade your battery life.

@ArtiePenguin1 4 ай бұрын

If you do full 0 to 100% charge cycles often, it will degrade your battery for most EVs. I would say 10 to 100% is safer than 0 to 90%. But it will vary slightly depending on the EV and the individual battery chemistry/engineering.
