Basic SOC & SOH values ​​via CAN

[sy-park]

Hello,

I want to see basic SOC & SOH values ​​via CAN to PCAN using aek-pow-bmslv. Is there any way to do this?

Hi,

Yes, it is possible to extend the CAN messages to send SoC and SoH just by defining dedicate functions in the function below.

As the code does not include SoC and SoH calculation, you should add the calculation routine based on voltage, current and temperatures read from the cells.

so, if i put this on the main, i am able to read the SOC and SOH?

Hi,

The answer is NO.

As clearly said in the below post:

           "the code does not include SoC and SoH calculation"

where i have to connect the positive of battery pack? cause the negative is J5 pin 7
