EVSE controller PCB

That looks really good.


Manual is clear this is for AC Charging, but I have one question:
If used with a CCS socket, do you see any interference with making the same socket support DC fast Charging later with another controller for the CCS communication? Or would that upgrade most likely also replace simpcharge controller for AC Charging? I guess this.

The SimpCharge will have to be replaced by the DC/AC Charging Controller as It needs to be in full control plus the DC controller will also handle the AC charging side due to the nature of the signals and required checks on the signals.

Thanks for clarifying, I was thinking about it sharing the type2 CP/PP/PE pins while writing, but because I wrote the question, I wanted to get confirmation for that.

As for type1 AC + separate chademo for DC charging, this should not be an issue?

Yes no issue the DC and AC charging here are even two seperate plugs so not shared at the socket and signal level. It all depends on how you handle it with the Vehicle Controller or BMS logic.

I do not know if its appropriate to discuss pricing anywhere but in the sales section, can create a topic there if required. Will create one once the first batch is in.

Having done testing I am ordering a batch and some enclosures to go with it. Hopefully will have an update on timing.

Pricing works out at 30GBP including VAT, seeing that this will have an enclosure it should be ok to ship with letter postage.

I would order one for testing please.

tnx

Nice work

Does it just trickle the charger or is there a way to adjust/limit the actual current drawn by the charger according the CP PWM signal ?

No it does not, as described earlier in the post. In combination with the SimpBMS it can do more.

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.

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.

Count me in on one unit for testing! Send me a PM when you are able to send

Any news Tom?

Any news Tom?

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.

[tom91]

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.

[tom91]

Have updated the manual, please have a look and let me know if anything is still unclear.

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

Can you please describe the spec of Pin 8 the “Conditioned Pilot Signal”.

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.
