Auxiliary Battery

Smaller battery pack separate from the main batteries. Serves several purposes:

  • Ensures the car still moves even if the main battery pack malfunctions mid-race (imagine if our steering and braking suddenly stops while we’re driving at 50km/h)

  • Used for car start-up sequence (aux battery “boots up” the car before we utilize the main pack for safety reasons)

Relevant tasks:

Battery Module Manufacturing

Our main battery pack is made up of 9 modules connected in series, with each module being made up of Li-ion 21700 cells in a 4S8P configuration.

Relevant tasks:

  • Module manufacturing

  • Bolt selection for series connections

Project Lead: Donna Kim

For more information:

BMS (Battery Management System)

Battery packs are dangerous to use without an electrical system that checks its health/state (temperature, current, voltage, charge balance).

The BMS actively keeps track of the state of the modules and actively protects the cells while also informing the driver of the state of the pack.

Relevant tasks:

  • Making the BMS

  • Board mounts

Project Lead:

Jenna Kim

  • Trello Card

Enclosure

The enclosure is the box that holds the main battery pack and also the BMS boards.

Relevant tasks:

  • Manufacturing finished product

  • Designing and CADING welding jigs

  • Managing HV ports (electrical integration)

Project Lead: Nicole Choe

As you can see, Battery Box is a cool mix of Mechanical, Software, and Electrical engineering, meaning it’s perfect for people of any background + if you’re interested in branching out to other engineering fields, or if you’re just interested in trying everything!
