Problem

Problem Statement

Create the battery pack which will supply the power requirements of MSXIV, and create the enclosure which houses the battery pack. Also assist electrical team in designing housing for circuit boards.

Goals 

To create a safe and lightweight battery pack which fulfills the car's energy  requirements under different driving conditions. The battery pack is one of the heaviest component of MSXIV. Streamlining the weight of the battery box will lead to less energy usage.

Constraints Regulations 
  • Provide MSXIV with its energy requirements (TBD)
  • Must perform within cell operating temperature (0~60 ℃)
  • Meet any safety regulations 
Criteria 
  • Significant weight reduction from MSXII
  • Lowered manufacturing time
  • Minimal cost
