Precision - DalyBMS #11

Closed n-benchoubane closed 2 years ago

n-benchoubane commented 2 years ago

Hi!

I was reading this post here

It is mentioned that they calibrate the voltage and current measurements with a 6 1/2 digit resolution HP/Agilent meter but from the program, this precision isn't displayed. Is there a way to modify and get the higher precision?

Thank you always! Nesrine

Hi, the program doesn't round up the values, it displays them with the same precision that gets from the BMS and as the Windows app does.

For which use-case do you need a higher precision? I'm using the data from the BMS to set limits for other devices (inverter, charger), but my battery pack is so big that I don't rely on multi-digit decimal values.

Hello!

I did a more thorough analysis and was able to confirm that it is due to the chip itself. Thanks for the quick response!
