This document is intended to be an extended version of the testing plan from the PVDR (preliminary vehicle design report).

...

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

...

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

E-load Setup

Procedure

1. Run serial_to_csv.py to check which thermistors are functional

2. Pause (Ctrl-C) serial_to_csv.py to complete setup

3. 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)

4. 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

5. Set BK Precision 8600 E-Load

6. Set Rigol DL3031 E-Load

7. Run serial_to_csv.py

8. End (Ctrl-C >> 2) serial_to_csv.py

9. ‘Save as’ the ‘data.csv’ file, as this file will be overwritten next time serial_to_csv.py is run

10. Follow charging procedure to charge battery pack to 13.2V, this leaves cells at 3.3V which is a good storage voltage.
