Hi there, thanks for your great work.
Is it possible to include the SOC (State of Charge) into the code?
Or do i have to calculate it by my own out of the Battery Voltage?

Thank You and a happy new Year!

The BMS gives out some more values. You can get them like this:
self.rawdat['Vmain']=int.from_bytes(self.response[0:2], byteorder = 'big',signed=True)/100.0 #total voltage [V] self.rawdat['Imain']=int.from_bytes(self.response[2:4], byteorder = 'big',signed=True)/100.0 #current [A] self.rawdat['RemainCap']=int.from_bytes(self.response[4:6], byteorder = 'big',signed=True)/100.0 #remaining capacity [Ah] self.rawdat['NominalCap']=int.from_bytes(self.response[6:8], byteorder = 'big',signed=True)/100.0 #nominal capacity [Ah] self.rawdat['NumberCycles']=int.from_bytes(self.response[8:10], byteorder = 'big',signed=True) #number of cycles self.rawdat['ProdDate']=int.from_bytes(self.response[10:12], byteorder = 'big',signed=True) #production date self.rawdat['Bal1-16']=int.from_bytes(self.response[12:14],byteorder = 'big',signed=False) #balance state cells 1-16 self.rawdat['Bal17-32']=int.from_bytes(self.response[14:16],byteorder = 'big',signed=False) #balance state cells 17-32 self.rawdat['ProtectState']=int.from_bytes(self.response[16:18],byteorder = 'big',signed=False) #protection state self.rawdat['SoftwareVer']=int.from_bytes(self.response[18:19],byteorder = 'big',signed=False) #software version 0x10 represents version 1.0 self.rawdat['SOC']=int.from_bytes(self.response[19:20],byteorder = 'big',signed=False) #remaining capacity [%] self.rawdat['MosfetState']=int.from_bytes(self.response[20:21],byteorder = 'big',signed=False) #MOS indication State, Bit0 Express charge, bit1 expression discharge, 0=MoS off, 1=open self.rawdat['NumberBat']=int.from_bytes(self.response[21:22],byteorder = 'big',signed=False) #number of cells for i in range(int.from_bytes(self.response[22:23],'big')): #read temperatures self.rawdat['T{0:0=1}'.format(i+1)]=(int.from_bytes(self.response[23+i*2:i*2+25],'big')-2731)/10

You can go here for a better understanding of the values:

The BMS gives out some more values. You can get them like this:
`self.rawdat['Vmain']=int.from_bytes(self.response[0:2], byteorder = 'big',signed=True)/100.0 #total voltage [V]

Thank You! I managed to read and parse all values using the documentation you mentioned already by me own.
