You could do but that would require a controller ect. this board/product is meant to be as simple as possible so it will consume a very tiny amount of energy when not in use and be very simple to use and produce thus keeping costs down.paaa wrote: ↑Fri Jul 03, 2020 4:35 pm Very investing idea , I am toying with idea of doing something similar but instead of output to simpbms, I would like to output a configurable 0-5v and or can bus signal indicating max power available based on pilot signal for controlling a charger that doesn't have J1772 support.

Re: EVSE controller PCB
my pcb assembly supplier had some delays at their end but has told me the PCBs have shipped this week.
So hopefully I can provide an update soon once they are tested.

Re: EVSE controller PCB
Good news everyone I received the pcbs and housings this week. Completed testing and now I am finishing the documentation.
The integration with the SimpBMS is also completed, had it all running on the bench in a hardware in the loop setup.
Pricing will be 32gbp including vat for the SimpCharge with mating connector.

Re: EVSE controller PCB
Hi Tom,
I have, hopefully, a quick question.
Can you please describe the spec of Pin 8 the “Conditioned Pilot Signal”.
I have an old AVC2, and use both an old granny cable at 10A and a standard Type2 at 32A 7kW, but have to manually change the charge rate. I’d like to use Pin 8 on SimpCharge to control the charge rate via my VCU, so it’s all automated.
Cheers,
Ian

Re: EVSE controller PCB
It literally is a buffering of the CP signal, so you need to have an interrupt capable output to be able to determine the duty cycle.
