TODO: Update

Midnight Sun’s Battery Box Team is in charge of giving the car power to move (as well as helping with electrical integration later on). Our main battery pack is essential for two functions:

1. Store energy collected from solar cells

2. Provide supplemental power for our vehicle, MSXIV, on days with minimal sunlight or when we want to go fast or up a hill (or all three at once)

We assemble hundreds of lithium-ion battery cells into a battery pack that provides the necessary voltage and current for our motors to power MSXIVMSXV!

Depending on whether you’re onsite (in the bay) or offsite (remote), you will gain exposure to different elements.

...

• Battery module engineering and manufacturing including but not limited to:

  • Manufacturing techniques

  • Adhesives

  • Spot welding

  • Bolted connections

  • High voltage safety

  • Battery testing strategies

  • 3D printing

• Attending weekly team check-ins and general meetings over the web (mandatory)/ in-person

For offsite members, you’ll gain exposure to:

• Design and analysis of battery pack components including but not limited to:

  • Research and design for battery testing and manufacturing

  • 3D printed mounts

  • High-current electrical connections

  • Data processing for battery tests (using python)Solidworks

  • Thermal simulation for module optimization (SimScale/Ansys)

  • SOLIDWORKS design for battery pack components

• Exposure to the supplier-interfacing process 

• Attend Attending weekly team check-ins and general meetings over the web (mandatory)

Required Skills

You are:

• A student passionate about design (interest in cars and batteries is a bonus)

• A hard worker, with the ability to complete tasks with minimal supervision (but we’re always here to help)

• A quick problem solver who isn't afraid to think outside the box

• Willing to learn new skills and improve your existing skills

• Strong time management skills for daily tasks and able to work on multiple projects simultaneously 

...

• Basic understanding of Design for Manufacture (DFM) and Design for Assembly methodologies (DFA) (combined, they’re commonly referred to as DFMA)

• Someone with exposure to a CAD package (SolidWorks SOLIDWORKS preferred)

• Knowledge of solid mechanics (stress analysis, failure methods)

• Exposure to rapid prototyping (3D printing)

• Basic battery building knowledge (e.g. series and parallel, cell module and pack levels)

• Exposure to technical drawing creation

To get you accustomed to navigating our massive and often confusing Confluence, on the left sidebar, please head to the previously pre-recorded recordings:

Mechanical space > MSXIV > Electrical Integration > Battery System > Zoom Meeting Recordings
