Regardless of AC or DC charge sources this a wet noodle for me. Unfortunately for me my highway options for charging are very limited in middle Canada( there are literally currently only 3 DC chargers servicing one major 500 km highway in Manitoba )and when you factor in the 30-40% loss of range due to cold winter weather I sometimes need to get a charge past 80% so that I have any chance of getting home from a distant jobsite.
Can you post the full url of the site you have done the screenshot of? I know some people that could help me do a better translation potentially.
Based on how, I *THINK* this reads, it sounds like charging speeds are normal up to 80%, then drops while it checks the battery and such check may take 10-30 minutes, then resumes back at normal speeds for the rest of the charging, but I really need the original link to better confirm.
If it is 1 kW charging at 62%, then that would indicate and issue with the charging station to me. And I have had my charging rate drop to 1kW at about 98% and other times remain at 7+ kw all the way to 100%. So as you, say we can't tell until there is either official confirmation from Hyundai or we see a pattern.
I am not particularly distressed about this as I feel I still can exercise my option of not participating in the recall if it does not makes sense to me. Sadly though the early anecdotal reports from South Korea are starting to confirm my fear that Hyundai is going to select the cheapest option( to themselves) to fix this problem. I am put off with the idea that a suboptimal software patch is the solution (who's burden of actual cost/inconvenience will fall on the owners of the vehicles) to what is suggested by Korean government as a hardware manufacturing defect.
80% sounds like a pretty arbitrary point too (and does not seem that realistic given people have seen that "1kw charging" at other battery SOCs). I guess we'll have more data as time passes.
Yup, I assume by the time December comes we'll have a bit more rigorous data and/or a better software update / battery change for affected cars
.
Some things never change.
I think that's exactly right. And, the reason behind the slowness indicated may be due to the capacity of the cell monitoring hardware to dissipate power to bring down the voltage of the higher cells in the case where there is an actionable variation. This could be a limitation that software cannot get around, e.g. size of resistors if passive balancing is used. When the charge rate is shown as 1kW, it's no-doubt just keeping the car's systems alive without drawing from the traction battery. The time required for balancing might be long at first but could improve as cells variations are tightened up.
I'm a little surprised they didn't take the opportunity to reduce the peak voltage just a tiny bit. it could be either due to hardware limitations or to avoid getting sued for reduced product performance.
I think that situation will remain and replacing the entire pack is still the only practical option. Checking balance occasionally using TP or SoulEVspy could give an early warning. I've had one that is always slightly down (~0.02) so I'm checking it frequently.
I would assume if a cell voltage is well below the average the "check" light is triggered.
I don't see how it's possible to measure cell voltages while charging. Charging must stop entirely and cells allowed to settle.
