Introduction: Arduino Battery SMBus Reader
A simple SMBus reader for most smart batteries
Reads the data from the TI chip set used in many smart battery packs
Step 1:
The 2x 1K resistors on data and clock inputs can be removed if you can’t get data
This was added for protection during testing other batteries with USB connection.
Step 2:
Original code was downloaded some time ago and heavily modified for formatting on Nokia display and getting data from larger battery packs (up to 8S)
Included the libraries that I used as these seem to change over time and the original code won't
More details are displayed via the Arduino Serial Monitor
Note the cell voltage displays 3 digits
Eg 356=3.56 volts
Cy = Cycles
CC = Current Capacity
DC = Design Capacity
DV = Design Voltage
V = Current Voltage
