Id like to start a thread for orion bms users and for future users.
State the setup and share some settings and ideas to help myself and others improve the setup and SoC reading.
Some canbus settings and tips and tricks for relay setting to have an external battery heater etc.
My setup is:
Orion bms 2
Battery: 3 modules renault zoe gen 1.
3 modules in serie of total 100V
estimated around 70Ah . 2.8V-4.3V
If anyone have a good setup for Kia soul cell or others that are not included in orion setup please share.
I was trying to configure the SoC reading but charging the pack from a low voltage , 2.8 to 4.3, to max voltage with 1/3 C rate. 20A in my case. Continuing reading voltage value and Ah to try plot the charge curve.
One problem I noticed is that if you already have drift points set in orion the Ah meeter will adjust, drift, to accumulated Ah value and therefore adjust the SoC value on the fly. So theres no Ah meeter in background calculating the total Ah you charge with. So top tip to do this in the beginning is to have no SoC drift points when trying to plot the first charge and discharge curves.
The shunt capacity is pretty good for balancing. They state up to 200mA. I had a module out of balance before starting and had to leave it balancing for more then 20h for reaching withing 0.05V with the rest of the pack.
