Battery Management System

Responsible Person(s)

• Designer: @Muhammad Tanveer , Eric Chiang

• Mentor: @Kevin Li

Principle Objective:

• Design a battery management system for our rotorcraft vehicle, Project VANGUARD

Requirements:

1. The system shall be able to accommodate 24V

   1. Stems from being able to accommodate a 6s battery

2. The system shall be capable of calculating currents of up to 40 A continuous

   1. The requirement stems from Motor Calculations

Goals:

Rev 1:

• The system will accommodate requirements (1) and (2)

• The system shall utilize an IC capable of monitoring at least 6 cells, and provide passive balancing and current sense capabilities for SOC estimation.

  1. Other features such as over/under protection are not currently necessary.

Rev 2:

• TBD given results from Rev 1

Timeline:

• BMS IC selection underway

• Initial Schematic: TBD pending BMS IC selection

• Layout: TBD pending initial schematic review

Implementation Notes

• Chip being used: TBD
