Modeling, Analysis & Design Project (50 points)
Due: 3:00 pm, Tuesday, July 19, 2011
Analyze the design of the major components of the electrical system on your
including battery, charging system, starting system, and headlights.
Identify your car: make (Ford, Toyota, etc.), model (PT Cruiser, etc.) and year
Discuss the purpose of each system, (battery, charging, starting and headlights), and
explain how each system works. Be brief.
Sketch or provide drawings and circuit schematics, as it pertains to YOUR CAR, or your
family’s car. List/ show all vital elements, and discuss.
Identify the major components of the charging, starting and headlight systems, discuss
their purpose, and explain how each component works.
Choose one major sub system from charging, starting and headlights, and derive
governing equations for this sub system by applying first principles such as Kirchoff’s
