Hello,
I plan to make a 333V Battery using AEK-MCU-C4MLIT1 as the master, AEKSCOM-ISOSPIA as the translator and AEK-POW-BMS69EN as the slave BMS Boards.
So far, I have been using the Example "SPC58EC—AEK_POW_BMS63EN_SOC_Estimation_Single application for discovery" to connect the Master to a single slave and receive cell voltages and temperatures. That has worked well.
Now, the next step of the project is to connect the slaves in a daisy chain and get individual data. Since the battery modules are supposed to be connected in series, I can't connect the slave boards using the USB connection. Thus, I have only connected the ISOH & ISOL lines.
As per the support document, I can't directly use the same example when I have multiple slaves. I should use the following examples:
"SPC58EC - AEK_POW_BMSWTX_SOC_Est_SingleAccess_CHAIN application for discovery"
However, I am not able to get cell data from even a single slave if I use this example, even when I change the connection properly. I am only receiving '0' values in the serial monitor every 1 second.
1. Could you please let me know what changes would I need to make in order to establish daisy chain correctly with my configuration. I tried changing the number of AEK-POW-BMS69EN nodes to 2 in the " SPC58EC—AEK_POW_BMS63EN_SOC_Estimation_Single application for discovery" Example but that didn't work.
2. If I have to use the "SPC58EC - AEK_POW_BMSWTX_SOC_Est_SingleAccess_CHAIN application for discovery" example, what changes should I make? I have already made the changes with the wiring.
3. I would like to understand further that would I need to implement the ISOSPI Transreceiver in a different Scenario Configuration if I have to implement daisy chain?
I have attached a photograph for my configuration. the Left hand side of the pack is the Battery positive and the right hand side is the Battery negative.
I highly appreciate the support that I have received from this community. Thank you!
