Design and Simulation of a series Hybrid Electric Vehicle (HEV) Powertrain

Design and simulation of Series Hybrid Electric Vehicle PowertrainBy Shaunak ChandwadkarHybrid and Electric Transportation

Agenda

Simulate and Optimize a SERIES HYBRID ELECTRIC VEHICLE Vehicle in consideration Chevrolet Volt Optimize the vehicle for increased efficiency and decreased pollution.

Series Hybrid electric powertrain

System Original Modified

Engine 75 KW 65KW

Battery 240V, 192 cells 240V, 210 cells

Motor 110 KW 120 KW

Generator 54 KW 65KW

Original and modification

Results

Acceleration performance increase

State of charge improvement

The increase in battery capacity resulted in increased SOC at the end of the cycle

HWFET cycle power losses- reduced

UDDS cycle power losses - reduced

Increased engine efficiency

Cost Reduction

Results

Acceleration Performance – 9.02 went up to 10.13 Mileage increased by ~ 3.5 mile/gal Cost reduction by around 500 $ Emissions stayed almost the same.

ConclusionSystem Original Modified Rationale

Engine 75 KW 65KW Cost Reduced,Mileage increased

Battery 240V, 192 cells 240V, 210 cells Less energy needed from engine to charge battery,Mileage increase

Motor 110 KW 120 KW Engine dependency reduced.

Generator 54 KW 65KW More electric power generation capacity.
