When you plug into your car does the display change from "Ready" to "Connected" or "Charging"? Does the vehicle give any indication that the plug has be inserted?
The issue is not likely the controller.
If the vehicle does not recognize the plug, the issue is the push button/latch. If the button does not click when you press and click again on release connected to the vehicle, charging will not begin.
You can test the button with a multimeter, if you measure resistance from the "Proximity" pin on the handle to the ground pin it should read 330 ohms and 480 ohms when pressed and released.
Type 2 still requires a resistor in the handle from the PP to ground. If the resistor is missing, the vehicle will not detect the plug.
|13 A||1.5 kilohms|
|20 A||680 ohms|
|32 A||200 ohms|
|63 A (3 phase) / 70 A (single phase)||100 ohms|
Testing procedure is the same, measure resistance from PP pin in handle to PE Earth.
What is the current capacity of the cable? A 32A cable should read 200 ohms. 10k does not correspond to any cable (see chart above).
The resistor in the handle is for the max capacity of the cable. Pilot is the max capacity of the station.
It is as simple as adding the correct resistor. Here is a guide that may help.
some progress in my OpenEVSe saga - put a resistor ( 180 ohm - so that makes the current capacity high but since I am setting the EVSe to 15A max, shouldnt matter ) inside the OpenEVSE ( handle is not easy to access ) PP wire down to groundplane - so now PP to PE reads 180 ohm.
So, it starts charging! hooray.. except it does an Error No Ground immediately after starting. Curiously, the Tesla will charge ok on 10A but as soon as I step it up to 15A , it also says Error No Ground. Kona craps itself immediately
Here is a guide to increase relay hold power.
Folllowing up on this, I have tried the settings advised in that article - and the reset
ie $Z0 200 127
$Z0 100 105
$Z0 255 255
The relay contactor does not appear to be making contact , ie. no KLAK noise at all after plugging into .car.
Just says "ready" and then connected when plugged in. Nothing more - there is still a 150 ohm resistance across PE-PP .
I am on firmware 8.2.0 EU
I'm not sure what more I can do.
I took it along to our monthly Australian Electric Vehicle association meeting and a few more people looked over it, nothing wrong with my wiring, inductor coils as they should be.
