KEBA Wallbox EVSE Heat Challenge (Video)


KEBA wallbox

KEBA wallbox

Nearly one year ago, KEBA participated in ALS Ice Bucket Challenge.

Earlier this year, the KEBA team continued demonstrations of performance and safety by preparing an unusual heat test.

The KeContact P20, 22 kW 3-phase wallbox was connected to charge smart ED next to 640°C (1,182 °F) hot steel slabs at the voestalpine steel plant.

Temperature on the surface of the station increased to 140°C (284°F) and KeContact P20 automatically suspended charging to automatically resume after it cooled down. That’s what KEBA stations are capable of.

“It all started last summer when the charging station KeContact P20 underwent an endurance test and KEBA transformed the famous “Ice Bucket Challenge” into the Austrian “Ice Cube Challenge”.

But does the wallbox withstand extreme heat and do the protective mechanisms of KeContact P20 work under the harsh conditions of a steel plant as well? To find that out, KEBA employees placed the wallbox next to 640°C hot steel slabs at the voestalpine steel plant.

The result: The surface temperature of the charging station took on 140°C and also the inside temperature increased accordingly. But for safety reasons, the wallbox stopped charging automatically. Only after the wallbox had cooled down and the cyclical recovery test was positive, charging started again automatically.”

    They probably spent more money on the test than they did designing the thing.

      Same thing with the Lexus hoverboard but money spent on advertisement is priceless…

      It’s not a marvel of modern design. And since that’s not what I expect from a wallbox, that’s just fine. I only care if it does the job well, and so far it has for me.

    Wonder how the Nissan DC ones would fare/perform? They are notoriously negatively commented on.

      How about Blink?

    What a joke! Another dumb test, which I suppose is necessary since Underwriter’s Laboratories does crappy testing compared to what they traditionally did decades ago.

    All I know is that the KEBO 3 kw unit outside the SMART dealership in the Buffalo area is broken more often than working.

    What’s the big deal with these KEBO or EMW tests anyway? They’re still overpriced glorified light switches. Doesn’t apply precisely to this article, but Its also amazing that there is a compatibility issue with the J1772, – eg: some Aerovironment units have such lousy 5 volt regulation on the data line such that some tesla cars (or Rav4EV’s) wont work with them. Again, what a joke..

      Did you mean Keba ? They are European, so have C.E. certification first, then U.L. I have bought many of them and they all work OK. Maybe there is a fault with the unit at the dealership. They definitely do a lot more than a light switch 🙂

  4. Bill Howland says:

    Les: “More than a light switch”

    Ok, what more do they do?

    1. Robert says:

      Bill, you surprised me with that question.
      You do know that light switches don’t communicate with the light to see if is ready for power before closing a relay to power it, right?
      They also generaly don’t switch of if there is a problem with the bulb or it fails to communicate with the light switch!
      Enough jokes for the day? Or, are you serious?

        Now that EVSE’s have come down in price, ((Ihate DISCUS)) they’re terrible

        bt a ht-tub GFCI wud do the samething

        1. Bill Howland says:

          IE spell check got the wrong word : supposed to be tolerable.

          EVSE’s are a needless complication and don’t add to the safety of the vehicle. I always believed that even before buying one 4 years ago.

          And since I had to FIX 2 issues with Schneider’s EVLINK, you might presume I understand whats going on with the EVSE box. Its more appropriate to ask Schneider if they know what THEY’RE doing.
