Arduino Battery SMS Bus Reader

256

5

A simple SMS bus 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)

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
