Chilly Charging profile of Hyundai Kona Electric



From 12 to 80 per cent to 4 degrees C (39.2 f).

Hyundai Kona Electric is on the verge of hitting shops in the United States, so it's probably a good time to look at how fast it is charging. Of course, the exact charge profile will vary slightly, depending on things like the output capability of the specific charger, ambient temperature and battery life. The video above gives us an indication of what we should expect to charge from about 20 percent to 80 percent at a specific 50 kW station when it is 4 degrees C (39.2 F).

Footage found on a YouTube channel EC mosaic suggests it can take longer than you can expect to pay when things get a little cold. As you will notice, the car only accepts energy at a speed of about 37 kW instead of 50 kW. Whether this is the fault of the car or this charger, it is difficult to say without more data. It's also worth noting that even this level of power falls to 23 kW after the battery reaches 76 percent full charge.

In any case, the host indicates a dilemma worth the effort. At this particular place for charging, the owners have an hourly limit. However, to get the car up to 80 percent, more is needed. There is not really a great solution for this, but it is one of those little frustrations that some owners might experience.

Video description:

In this video, I document the normal day of Kona Electric's ownership.

Starting with a 45% battery and a marked 125-mile range, we are planning two trips.

The first, about 60 mile round trip followed by a second of about 45 miles. My first instinct is to add an hour or two home charging to our 7.2-liter Zappi Charger, adding 40 or 50 miles, which is a nice additional accessory, but with indicated 20-mile contingencies I could just "go for it" and see how much is close it gets, charging when I'm home.

I would like to see how accurate GOM is at lower% levels and therefore this is a good example for testing. But with winter driving in very cold wet conditions, maybe the risk of leaking is not the wisest choice. So I decide to stay on the way home, to charge a quick charger, adding a 10 mile additional contingent, while simultaneously testing how GOM is changing.

Results:

125 of the project,

57 miles traveled,

65 miles range remaining (3 miles lost) 21 miles more driven

Remained 38 miles (-6 miles)

12 miles more drive remaining 28 miles (received +2 miles)

(125 – 89.5 = 35.5 expected against 28 current ones)

Therefore, in cold conditions, the GMM in half full may be 10 miles off, although with a slower drive (40mph) it is possible to get a few miles because the SPC reduces to very low levels.

The quick charge offers 36 / 37kw from 12% to 76%, where it falls to 23kw to 80%.

An hour is charged from 12 to 66%, but up to 80%, totaling 76 to 77 minutes, which is part of the time quoted by Hyundai.

According to previous videos and examples provided by other participants on YouTube, there is no logic why during this fee the rate could have been raised at some point above 37kw. On this occasion, it actually feels like a charger can limit charging. If not, it just does not make sense.
