Re: Zoe 52Kwh Battery Storage

It would depend how depleted the battery was, and what tarriff you're on. In my case, almost always yes.

No wiring diagram. If you're looking to replicate this, there is a community built up around https://github.com/dalathegreat/Battery-Emulator

Re: Zoe 52Kwh Battery Storage

Re: Zoe 52Kwh Battery Storage

I believe the balancing issue is now solved by sending accurate time information to the pack via the canbus. There is more information about all the LBC can frames here https://github.com/ljames28/Renault-Zoe ... nformation

Re: Zoe 52Kwh Battery Storage

The connector is the same 12 Pin 7282-8854-30 but the pinout is different, pinouts attached. These are from Renault "New Dialogys" which you can pay for, for just an hour, to get diagrams and pinouts. For the relays to work you'll need to connect that "HYBRID 3 Relayed" pin, but I can't remember if ...

Re: Zoe 52Kwh Battery Storage

Ah okay. I've been controlling charging via max_charge amps and it seems to work well, it's very quick to respond and can keep the battery at a specific charge level that way.

One modbus talks to Fox on the normal RS485, another is for my main Modbus network with multiple devices, and the other is ...

Re: Zoe 52Kwh Battery Storage

Ah sorry I got confused. I use CAN bus to talk to the Zoe and the Battery side of the inverter. Seperately Modbus to talk to the data side of the inverter. I've been controlling the charge from the CAN side, by setting the max charge amps to stop/start the charge. I only use the Modbus to read data ...

Re: Zoe 52Kwh Battery Storage

Yes I'm using Modbus for both Zoe and Inverter comms. My code is quiet specific to the environment I use, but it's based on wolegs CAN sniffing here https://github.com/rand12345/solax_can_bus

The battery pack came from EV Breakers in Northern Ireland. The DC is connected to a FOX ESS H1 6kw high-voltage hybrid inverter via a MCB. The ...
