Ok thanks. Yes I jumpered the 3.3V to get it all working and seems to run well.

I’ll take a bit more time looking at the gauges and see what I can find

It should, the first iteration had an error.on the board. The use a usb cable with the 5v cut


Ok thanks. I must have got the older file as there was definitely no connection to 3.3V or 5V. I guess it’s preferable to use the 3.3v?

Also did you get a chance to find out how to change the ...

Charging been going well. Am sending across my BMS data finally and updating Soc and is working well. Ramp down and shut down working so last thing will be the ramp down when battery temps or cell voltages get high etc. Just working out what that needs to be.

With regards to powering the ESP32, I ...

Testing is proving great and also implemented a ramp down feature to go from CC to CV and seems to be working well. Just added in the complete shut down after it gets below the minimum charge current so will test that today.

Have been playing with the web pages just to make them look a bit nicer on ...

So the initialise worked but I think something is up with web interface files as the esp got very laggy and would keep dropping the web connection etc and I struggled to upload the files. If could be in the main code, started to check that out but then had to head to a job

Ended up re-loading ...

I gather that would initialise each time it started up then huh?

Where would be the best place to put it? Could come after sendStatusToVCU()? I havent changed anything so can1 should be the can for the shunt.

Is that code you posted the exact code or does it need some massaging? I can give it a ...

Could do either way, adding an initialise to the current code would be nice.

It's not coded to do so, it's pretty much the same code as other implementations ported to ESP32. I get to about 90% with this implementation, but wouldn't take much effort to implement a ramping down.

Shouldn't need a DUE specifically, just need to send a few can messages.



I guess I could ...

Sorry, somehow missed this.
From new the ISA shunt uses big endian and doesn't output as much data https://openinverter.org/wiki/Isabellenh%C3%BCtte_Heusler has instructions to swtup


Thanks for your reply. That would explain why I am not getting very far. I can get it to charge and for the most ...

Thanks, Matt.

So seem to have got this sorted by changing the Endian order and reversed it. Screenshot of code fix attached.

Hey, great work and good to see the esp32 being implemented for this.

I have added a range extender pack to my 2015 outlander so taken the EV range up to wound 140kms so pretty happy with that.

I have purchased the boards and all the hardware and are currently setting up a test setup for this. I ...
