What do you recommend for the number of cells in series and parallel, and why did you choose those numbers - we’re looking for an answer in the form of XPYS, where X is the number of cells in parallel and Y is the number of cells in series, along with a justification.

Step 3

Draw a sketch of the cell plate holders (what will hold the batteries in place to make the connections, see below for an example) you would 3D model for your answer, a simple design will work. This will help you on the working session on the 16th when we design cell plate holders together on SOLIDWORKS

Step 4

Now that you should know how to design a battery pack, we’ll get you to run through the process of choosing a battery configuration for a car, given the following parameters (chosen to loosely represent Midnight Sun XIV):

Submit your answer to Nicole Choe or Shem Kim through Slack and then we can discuss some more in detail about your answer. Afterward you complete onboarding, we’ll have a 1-on-1 meeting where we will be going over what your goals are for the team, what you want to work on, so I know what projects to assign to you!

Step 5

After you get your answers confirmed with Nicole Choe or Shem Kim, use SOLIDWORKS to CAD a very simple cell holder for a 5S1P Battery Pack composed of five 18650 cells. This is meant to be a fun project! Don’t over-think it. We want to see a top cell holder, a bottom cell holder, and five 18650 cells in an assembly. If you are having trouble with getting access to SOLIDWORKS, reach out to us and we’ll help. If you are having trouble with making the CAD, there are a lot of tutorials on YouTube, but you can also reach out to us for help. We highly encourage everyone to try figuring it out by yourself though, self-learning is a very important skill that you will need in the team!

Once you are done, send pictures of your assembly design to Nicole Choe or Shem Kim to get it quickly reviewed. Once everything is good, we’ll help you 3D-Print your design and create your design!
