3.2 SM COM Tool

The SM COM Tool, shown in Figure 3-1, is used to control the source meter to run the battery test case, and show the data measured by source meter. The record data is saved in the CSV file with a name time-SmData.csv. If users want to recreate this part for software, then install NI_VISA. For hardware, users need a USB to rs232 wire and a keithley 2602A source meter.

As the source meter is not an equipment solely made for BMS, consider the limitations on the BMS test. For example, the source meter cannot support high current control with high voltage battery. This can trigger the AFE into protection mode with constant current control because the battery voltage changes above the threshold set in the AFE.
