myenergi zappi [Unknown Cable]

An untethered zappi has to be told what cable it is wearing, and the cable tells it through a resistor inside the plug that encodes the current rating. Unknown Cable is the message when that value does not match anything the zappi expects. myenergi’s definition is that the zappi has detected an unknown EV cable, on untethered units only, and their remedy is a specification: make sure you are using genuine IEC 62196-2 compliant plugs, with the supported range given as 32, 20 and 13 amps.

As with the pilot message there is no reset to perform; the zappi will automatically retest the cable after five seconds, and if the issue persists their advice is to unplug the cable, check for dirt in the plug and try again. The two things that produce it are a cable that genuinely is not compliant, which is common among the cheapest online listings and among adapters, and a compliant cable whose proximity pin is not making contact because the plug is dirty, wet or not fully seated.

Since the rating the cable reports is what the zappi uses to cap the current it offers, this check matters: a cable that reports nothing might be one that would report wrongly, and the Overload code is what happens when a cable’s claim and its construction disagree. A tethered zappi has no socket and cannot show this message; if you have one and think you have seen it, look again at the screen.

1. 1

   Unplug the cable from the zappi socket, check the plug face for dirt or moisture, dry it and push it fully home. Wait five seconds for the retest.

2. 2

   Check the cable’s markings for EN 62196-2 and a current rating of 13, 20 or 32 A. A cable without a rating marked is the likely cause.

3. 3

   Try a known compliant cable if one is available. If it is recognised, the original cable is the fault and should be replaced rather than persuaded.
