From 12 to 80 percent to 4 degrees C (39.2 F).
Hyundai Kona Electric is on the verge of hitting sales outlets in the US, so it's probably the right time to look at how it speeds up. Of course, the exact charging profile will vary somewhat, depending on things like the output power of a particular charger, ambient temperature, and battery power. The top video gives us some indication of what can be expected from 20 to 80 percent at a particular 50 kW station when it is 4 degrees C (39.2 F).
Recordings found on YouTube Channel EV Puzzle suggests it can take longer than you would expect to charge when things get a little frozen. As you will notice, the car receives energy only from 37 kW instead of 50 kW. Whether it's a car or this charger, it's hard to say without additional data. It is important to note that even the power level drops to 23 kW after the battery reaches 76% of the full charge level.
In any case, the host points to the dilemma of valuable reinforcements. At this filling point, owners have a one-hour limit. However, to get the car up to 80 percent, more is needed. For that there is not a really good solution, but that is one of those little frustrations that some owners might experience.
In this video I document the normal day of ownership of Kona Electric.
Starting with a 45% battery and a range of 125 miles, two trips are planned.
First about 60 miles a return journey follows another of about 45 miles. My first instinct is to add an hour or two home charging to our 7.2kw Zappa Charger, adding 40 or 50 miles, which is a nice addition to the unexpected situation, ALI with the indicated 20-mile contingent that I could only "catch" and see how much is near getting, filling when I'm at home.
I would like to see the accuracy of GOM at lower levels and this is a good example for testing. But winter driving in very cold, wet conditions may be risky exhaustion. So I decide to stop on the road home, fill in the fast charger and add an additional 10 miles, while testing how the GOM changes.
57 miles traveled,
The remaining 65 miles (-3 miles lost) 21 miles more
Remaining 38 miles (- 6 miles Missed)
Remaining 12 miles (28 miles)
(125 – 89.5 = 35.5 expected with 28 real)
It seems that in cold conditions, the GOM half-full distance can be 10 miles away, though with slower driving (40mph) it's possible to get a few miles because SOC lowers to a very low level.
The fast charge offers 36 / 37kw of 12% up to 76%, where it drops to 23kw to 80%.
One hour charges 12 to 66%, but up to 80% of the total runs for 76 to 77 minutes, which is less than the time stated by Hyundai.
According to previous videos and examples of other YouTube collaborators, there is no point in why this rate would increase at a point above 37kw during that billing. On this occasion, it actually feels that the charger may have limited the charge. If not, it just makes no sense.
