Hello everyone,
I would like to show You My new battery BMS project aimed at safer and better space efficient energy storage solutions using NMC car batteries and LFP "bricks".
I wanted to create all in one BMS that serves HV ESS for HV PV inverters. I have full Can communication using Pylontech CAN protocol. It works with Solis, Sofar, Deye, GoodWe inverters (tested) and all others that are compatible with Pylontech ESS.
It's based on NXP Daisy Chain architecture.
The main objectives we have had is :
- Remote access to battery from WWW (LinkCloud) and Home Assistant integration
- Plug and Play, standalone (PDU)
- Highest possible quality of components and overall design focused on safety and complying with EU regulations.
What we have created meet all those criteria and I can proudly present You something what I have called : LinkBMS
Quick specs :
7-14S Slave unit
30 Slave units per master
50A constant current load on PDU unit
CAN, Ethernet, WiFi, Screen, Cloud, Home Assistant, Standalone(self powered)
You can connect it to NMC 3.7V , LFP 3.2V, LTO 2.2V.
Here are some photos of this BMS in a 82kWh 96S battery build out of VW 8S3P LG modules:
I am the most proud of the Power delivery unit (PDU) which consists of :
- Precharge Resistor + Precharge Contactor
- Isolated voltage measuring unit with it's own start procedure (short protection and capacitor charging detection)
- TWO main contactors both for + and -
- Current sensor
- 800VDC 80A fuse
- M6 Terminals
- 1000VDC -> 12VDC Converter supplying power to Master Unit and powering the contactors
It's developed for 50A of continuous current and max 800VDC.
More info can be found on my site LinkBMS.eu or email me directly. linkbms.eu@gmail.com
Would love to hear your thoughts and experiences, especially if anyone has worked on similar projects or has insights into
the latest breakthroughs in BMS tech!
Looking forward to the discussion.
