Re: Open source CCS using AR7420

I hope the below are my last few questions to clarify :lol: I plan to hack a GBT DCFC to convert it to a CCS2 plug. Starting with a 15-20kW model. The electronics I'm planning to make are a. the SECC side resistor-voltage control to respond to the EVCC as well as the PLC DC comm (sort of a front end...

Re: Open source CCS using AR7420

Thanks uhi22 for your reply. If that's case, i hv below questions: :) I'm trying to emulate as a DC EVSE. 1. In the arduino code snippet, i can define my own voltage (and obviously the cct to go with it) to trigger the code to send out 5% PWM? 2. A2 is not connected to any type 2 pins? eg. CP 3. At ...

Re: Open source CCS using AR7420

great project this is. hats off to all of u. especially uhi22 and celeron55. Hi @uhi22 , could u help show me directly the EVSE circuit described as "and the poti on left border to select 5% PWM." in your https://github.com/uhi22/pyPLC/blob/master/doc/EvseMode.md ? I just could not wrap my...
