Re: Renault Zoe Mk1 (2012-2019) - Basic Hardware Overview
If its supposed to be CCS EV to ChaDeMo EVSE it would be more complicated. Yes, this is the plan. I suppose it would be easier to start with an open ended implementation of CCS and then patch in the mocked CHAdeMO vehicle as middleware. Are you aware that the Ph.2 has (different to Ph.1) a DCB modu...

Re: Release: HVDC battery emulator project for ESS - Testers wanted
I’m not 100% sure but from a quick search that Mercedes uses CATL packs. The only interface I know that works with this tech is the MAX178xx controller. This thread should put you in the right direction. https://openinverter.org/forum/viewtopic.php?t=2181&start=25 I do have some spare SPI MAX178...

Release: HVDC battery emulator project for ESS - Testers wanted
Hi, Thought I'd share my £12 off the shelf setup, no soldering required! I wrote a Solax battery emulator almost 2 years ago now and have been using that code to use unmodified Renault EV batteries on Solax and FoxESS kit. Over the years this was adapted for 65V Victron kit (BYD emulation) and so on...

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
Modbus control is done on pins 3 & 4 (Modbus Meter is 1 & 2)
There's a discussion here for driving the inverter manually. https://github.com/nathanmarlor/foxess_ ... ssions/513

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
There’s no need to simulate a power meter, you can drive a FoxESS manually by commanding power. I’ll edit this comment with a link to their internal communications specification document.

Hey there, I may able to help you out with your Zoe PH1 CAN data. Let me setup a repo and I will add some DBC files and an extensive collection of logs (which I think were found in here).

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
For the V2X application, I already need to accurately report battery current to the ChaDeMo CAN interface. By offsetting this and reporting to the inverter via RS485, I can control the charge / discharge current. I have a copy of the official CHAdeMO spec and built my own library based on it. Dala’...

I am probably wrong on that. Found this from last year. > The project is designed to play both roles, EVSE and car. To work on the project, I just open two console windows on the same machine, start in the first window the EVSE with "python pyPlc.py E" and in the second the PEV with "...

Re: Open source CCS using AR7420
I see you have confused pyPLC.py P as a pseudo vehicle. Not just me then…
There’s no vehicle simulator here from what I can tell. P is for translating CHAdeMO can to CCS from what I can gather.

Re: Model 3 High Voltage Controller
I can see the voltage in can data and on the meter, the contactors close initially because target voltage is reached. Going to change the capacitor and see what happens.

My fault condition is like your fault but I have no load. I needed to power cycle the BMS to restart the precharge state. I have used the same capac...

Re: Model 3 High Voltage Controller
Thanks for responding OOP. My issue is happening with no load (nothing connected) on the HVDC lines, did your contactors stay closed when you did not have the inverter connected?

I have a complete dump of the BeagleBone file system, and both can1 and can2 logs if anyone is interested.
Tempted to DIY my own V2G as a V2H this summer.

Re: Model 3 High Voltage Controller
I have an odd contactor issue with one out of two M3 packs. Pack 1 is dated 2020, pack 2 is 2021. I have no issues with pack 1, contactors closing and all is well. Using exactly the same routine as bielec's ESP32 code, pack 2 will only close the contactors for approximately 60 seconds before opening...

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
I think the other 0x1871 frames are for can slaves, I noticed differences on the BMS version screen when responding to them. Can’t be sure though.

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
I think that cell voltage data goes in there too but I don't have a V2 FoxESS BMS master to get a can log from. You can see cell voltages on their cloud platform, numbered 1-141 IIRC.

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
One thing you can do is stop sending can frames to the inverter when your cell voltages are out of spec
I'm quite anal about safety, it's all too easy to make a mistake in code. Do you have a BMS monitoring the cells?

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
Drop your remaining_kWh, * 0.1 should suffice. I assume you don't have 95.7kWh installed. Set pack_volts_min to 860 (86.0V) and see what happens. I think the minimum spec is 85V (?) Other than that I would double check your CT setup. If that reading is wrong the inverter won't do anything. It should...

Re: Fox ESS H1-5.0-E ~33KW Peugeot E208
Brill, just be super careful. If the inverter receives an SoC under 100% and a max charge current > 0 then it will blindly charge your cells to destruction. You are the BMS master now.
