Testing EVSE without EV
OpenEVSE Support
Control pilot must be working in order to test. You can simulate a vehicle by connecting an 880 Ohm resistor and a Diode in series from ground to Control Pilot.
Thank you for your reply sir...
Dear support, this post is the closest to what I intend to do. I am in the midst of my own EV conversion. I have a 24S battery pack, so I want to set the EVSE's output voltage to 100.8V. How do communicate to my EVSE to set the output voltage level via the control pilot wire? Thank you for your time.
Hi ,
We had tried the same steps to test openEVSE, but it didn't work.
We had exactly followed the same steps as mentioned below
"Control pilot must be working in order to test. You can simulate a vehicle by connecting an 880 Ohm resistor and a Diode in series from ground to Control Pilot. "
The openevse page was loading but it didn't show any reading for the current and the power consumed.
Could you please help
Best Regards
Sathya

When testing the pilot with a simple resistor and diode, there will be no load on the station so no current or power will flow. If you need to test power flow a load will need to be installed on the output such as a electric heater.
Here is a guide on testing.

How can i test my EVSE without connecting it to the EV? Can i connect the output of the contactor to a lamp load (without connecting these output terminals to J1772) by leaving the control pilot and PP open ?
