JK BMS integration #128

Open kochikame opened 8 months ago

kochikame commented 8 months ago

Hi, What would be need to be integrated with a JK BMS DIY battery? What is the part I have to change in code? I would like to connect the Fronius inverter with my ome brew batteries and I would like to share it too. Thnaks in advance!

@kochikame JK BMS is for max 24S. This project is focused towards safe re-use of complete 96S 400V EV batteries as-is.

To use JK BMS, you would need to build a 96S pack with multiple JK BMSes at the same time. This is quite massive task to build and integrate. So I do not think it really suits the 400V use case here for a Fronius inverter. But this is open source, so feel free to attempt it :)

Thanks for the feedback otherwise it could be a good challenge Another two questions... The project is for GEN 24 Fronius inverters but could it work on other inverters with BYD ready compatibility ? Where do you buy LEAF batteries? (reliable) Thanks and congrats for the project

I'm working on a JK BMS integration for this application. I'm almost finished.

kochikame commented 8 months ago

@alexsve1990 I suppose you are programming a class to interface with JK BMS and collect all the info of several JK BMS and pack them as if there were from LEAF like? If I can help let me know. I am very interested in this optoin due I can not find a decent second hand LEAF 24kw

I also almost finish a JK BMS develoment, consists in several JK BMS 24 packs to get almost 300 volts I am implementing JK protocol individualy for each pack with a M5STACK CORE (very nice) And then I will try to gather all the info in the LilyCAN and reuse the code to transmit all escential data to the inverter I will keep on posting...

Hey, 200V should be enough right? Because I plan to start a Project with 64s consisting of 4x16s bms. Do you already know how you balance from one bms to another? There are stackable active balancer, but then you cannot use the jk bms with active balancing right?

Any news?
