Goals
- Determine the method of connecting cells together
- Determine the manufacturing techniques - including suppliers
- Determine a timeline to manufacture the modules
- Discuss a time to meet with mech to discuss a mechanical support - Contact: Adam Marchand
Discussion items
Time | Item | Who | Notes |
---|
5min | Sunstone Call | Minghao Ji | - Tony our contact did not pick up - therefore spot welder is a no go
- Supply Nickel tabs that fit our required dimensions
|
10min | Compression Pack Update | Minghao Ji Titus Chow | - The compression pack manufacturing technique turned out to messy
- Low trust in the compression pack
- Attempted to modify the compression pack to reduce the flexing
- Led to huge assembly problems and pains of manufacturing
|
30min | Spot Welded Module Update | Minghao Ji | - Use insulated fiber glass tubes to link multiple modules together
- Same Module size/layout
- 8 modules in a string, 4 tubes run full length of the 8 modules
- 3 Copper bus bars running in between each of the 3 rows of a module
- Side bus bar to the top off the module
- Ventilation in parallel with the cells
- Copper bus bars to connect strings together
|
10min | Testing Methodology | Taiping Li | - Use salt water load, and measure current, voltage and temperature of the module to understand the capacity.
- Create a vibe table and test the weld durability of the module
|
Action items
- Taiping LiGet a spot welder
- Minghao Ji Source nickel strips and tinned copper
- Manufacture prototype module before midterms.
- Tak Alguire Schedule meeting with Mech to discuss mechanical questions and battery box design
- Goal is to test the prototype module before Hell week
