Production Module Validation:

Battery Performance Validation:

To validate “completed” battery modules a full/charge-discharge test is required while monitoring system parameters, such as voltage and temperature. While unlikely, that modules are continuously discharged at 40+A, this validation procedure serves as a stress test.

1. Charge module to 16.6V (below max, as a health-span buffer)
   Owen Li to complete procedure.

Equipment

• BK Precision 8600 E-load

• Rigol DL3031 E-load

• 6, 18AWG wires with banana connectors

• A2D DAQ w/ thermistors

• USB to USB B (Data-Transfer Cable)

• Windows Laptop

Software Setup

• Follow the instructions here: https://github.com/kostubhagarwal/module_test_data_acquisition

E-load Setup

Procedure

1. Run serial_to_csv.py

2. Connect working 6 thermistors to the battery module busing

   1. use electrical or kapton tape

   2. connect to 6 different spots on the module as shown (the negative end of cell is preferred)

3. Connect E-Loads to battery module as shown DONT MESS UP THE POLARITY OF TERMINALS (BATTERY & E-LOAD)

   1. two wires (one for each terminal) to connect BK Precision 8600 E-load to battery module

   2. use four wires (double-up for each terminal, as wires are not rated for 30A) to connect Rigol DL3031 E-load to the battery module

4. Run serial_to_csv.py
