perg67 Posted August 7, 2020 Posted August 7, 2020 Is there anyone that has found out what the pinout are for the 8 pin RJ45 serial port on the powercube batteries H48050? And as a follow up question... is there anyone that has tested if the Batteryview program is compatible with these batteries? (That was my idea to test when I had found the pinout...) Quote
perg67 Posted September 8, 2020 Author Posted September 8, 2020 I finally found out! There is 8 pin RJ45 marked rs232 on the BMS sc0500a-100s (I have 7 pylontech H48050 connected to the BMS). I connected a normal ethernet cable and wired: * white green cable to pin 2 on the 9 pole dsub female * green cable to pin 3 on the 9 pole dsub female * brown cable to pin 5 on the 9 pole dsub female Connected the dsub to the serial port on the PC. (USB to serial adapter). Started putty and opened the port on 115200 baud. Press enter and the pylontech debug menu is opened. Quite impressive of all data you can read outl Everything from statistic, cycles, voltage on each single cell, alarm and event history. The pylontech enginners has made a good job and I'm happy they has left this debug info open. It will make it very easy to troubleshoot if/when a battery fails. Example of print-out: pylon_debug>stat @ Device address 0 EvenData Items : 35 HistData Items : 512 MiscData Items : 128 Charge Cnt. : 0 Discharge Cnt. : 4954 Charge Times : 3093 Status Cnt. : 4953 Idle Times : 4901 COC Times : 0 DOC Times : 0 COCA Times : 0 DOCA Times : 0 SC Times : 0 .....printout shortened here.,,, RV Times : 0 Input OV Times : 0 SOH Times : 27 BMICERR Times : 0 CYCLE Times : 56 Pwr Percent : 74 Pwr Coulomb(mAS): 132380712 Pwr PercentWatt : 73 Bat CoulWatt(mWH): 116859014 Dsg Cap(mAH) : 2848357 SOH Percent : 100 His.Chg Cap(WH) : 637783 His.Dsg Cap(WH) : 632016 Day Chg Cap(WH) : 0 Day Dsg Cap(WH) : 2730 Min.Chg Cap(WH) : 0 Min.Dsg Cap(WH) : 2730 Command completed successfully $$ As an example, the above info shows 74% battery remaining today, I have charged them 637 kWh and discharged them 632.

Denarius Posted September 8, 2020 Posted September 8, 2020 Hi @perg67, which USB to serial adapter are you using? I think normal serial is 12V while others are 3.3V: https://electronics.stackexchange.com/questions/274287/what-is-the-difference-between-rs-232-and-ttl-uart Quote

Stromer24 Posted June 2, 2024 Posted June 2, 2024 I had trouble to connect as well and the details from @perg67 did help me to get a connection with Putty. I have PylonTec SC0500A-100S with four H48050. Following was used: - LogiLink AU0034 - USB 2.0-Adapter, USB-A to DB9 (RS232), active Adapter with Chipset: FT232+SP213 ==> https://www.amazon.de/dp/B00ECJEPKQ/ref=pe_27091401_487024491_TE_item The "FTDI" driver needs to be installed. Driver download: http://www.logilink.de/download/driver/AU0034.zip Note: my virus-scanner did warn about one of the older driver files: I have deleted those; you only need: AU0034\Driver\Windows\CDM v2.12.28 WHQL - RJ45 to RS232 Serial DB9 9-pin Adapter ==> https://www.amazon.de/dp/B0B67K84VZ/ref=pe_27091401_487024491_TE_item For this RJ45 connector I have used an RJ45 to RJ45 adapter and another standard CAT5-cable, since I did not want to cut the cable of the "RJ45 to RS232". The only wire that needs to be re-wired on the CAT5 cable with this adapter is: (BMS-side) brown - white/blue (PC-side) Since the command line interface with Putty is limited and the "BatteryView" program did not connect, I have written a tool to run on Windows. It can be downloaded from here: ==> http://www.mmbsystems.de/download/MMBBatViewer.zip Quote
