Update quick start guide for BMS boards and examples version 2.4.0

[alfonso_mauro]

This GUI works with AEK-POW-BMSWTX? And if it does, I just connect the board to the PC or I have to configurate with autodev?

Thank you so much

Hi Alfonso,

yes, the GUI works with the AEK-POW-BMSWTX, too.

You need to install AutoDevKIt and import the dedicated demo:

You should also import the AEK-POW-BMSCHAIN component.

I'm attaching here the quick start guide to use the GUI, where you can find the detailed procedure.

You can also find additional information on the related user manual (UM3185 on www.st.com).

The examples you will find are related to a particular MCU board, but the procedure is the same for all other boards based on the SPC58EC MCU with other BMS boards of our portfolio.

I hope this helps :)

thanks a lot. and what about the AEK-POW-BMSLV? It has to be configureted too by autodesk? 

I have to buy other things or just the board?

the GUI works with this board?

It's possible to connect more than 14 cells on this board?

thank you so much

Hi Alfonso,

the GUI doesn't work with the AEK-POW-BMSLV (it's the only not supported BMS board).

The board supports from 4 up to 14 series-connected cells (so, unfortunately, no more than 14).

You can use the board with a specific demo in AutoDevKit: "SPC58EC-AEK_POW_BMSLV application for
discovery".

For detailed info, consult our user manual: https://www.st.com/resource/en/user_manual/um3371-how-to-use-the-aekpowbmslv-battery-management-system-evaluation-board-for-lowvoltage-applications-stmicroelectronics.pdf , Section 2 How to use the AEK-POW-BMSLV, Section 4.2 How to import an existing project and subsequent sections 4.3 and 4.4.

You should buy a dongle (e.g. AEK-MCU-SPC5LNK: https://www.st.com/en/product/AEK-MCU-SPC5LNK ) to program the onboard MCU.

I hope this helps you more :)

i follow all the steps, i have this on my pc

Hi Alfonso,

the screenshot I see in your post is correct.

Now, you have to follow Section 4.3 How to program the SPC58EC80 microcontroller as written above to debug the MCU.

You need the dongle as written before: "You should buy a dongle (e.g. AEK-MCU-SPC5LNK: https://www.st.com/en/product/AEK-MCU-SPC5LNK ) to program the onboard MCU."

Then, read section 4.4 AEK_POW_BMSLV_Demo_Code
"The purpose of this demo is to show how to read the voltages and temperatures of a 48V battery pack (14 cells)
and how to address the high-side power drivers of the VNQ7050 by monitoring their current consumption through
a sensing network with a specific fR_sense value..."

Of course, as you cannot use this board with the GUI, you will need a serial terminal to read voltages and temperature.

I hope this helps :)

what about if i want monitorate just 4 cells? what i have to change?

[Max VIZZINI]

Hi,

There are few tricky points:

1. Make sure that with your type of cells reach the min voltage and avoid Under voltage protection

2. The cells you need to connect cannot be random but the first 2 and last 2 of the 14 series

3. You have to make sure to put in series connection all the other unused 10 channels pins to avoid wrong voltage readings.

All details are present in the User Manual.

i have been talking about the code. there are some changes?
