Post Orion BMS Jr
on: October 21, 2016 (GMT)

Hoping someone could help me out on this..

I am working on a prototype for a lithium power system and am having some PID issues with the Orion BMS Jr

The PID is 22F027, Equation ((A*256)+B)/10 this is for the average AMP’s from the BMS. Everything works fine until the unit goes it to a charge stage(or negative)… then the numbers go crazy (shown in the pic’s)

The second option is to figure out how to get the average AMP’s on another PID which is 22F015 Equation ((((A*256)+B)-32767.0)/10)*-1. This shows the real world AMP’s but it bounces all over the place. Which is hard it get a base line off of. Have tried AVG(10:A+B)((((A*256)+B)-32767.0)/10)*-1 but it just shows up as 0. The Equation on this one is probably operator error… lol

Thanks for the help,

piemmm

Hi

is A/B two’s complement? You may need to use the SIGNED(A) function to get the negative numbers in the correct format
