Plug-In Hybrid Electric Vehicle
Has an External Port for charging the Vehicle.
Can be charged from wall socket. During Starting, if SOC is low external
power source may charge the battery instead of engine.
Can have an On- board Charger to increase the range.
Two types-Parallel and Series.

Autonomie - A simulation tool Autonomie is a Plug-and-Play Vehicle
Model Architecture and Development Environment.
Math-based simulation environment. Autonomie is an open architecture to
support the rapid integration and analysis of powertrain/propulsion systems.
The software has been developed by Argonne labs

Strategy and Cost function Initially Particle Swarm Optimization was proposed
to be used. Used Trail and Error technique to successfully
optimize the Cost function. The Cost Function here is Improving Fuel
Economy and reduce emissions. Cost Function = , X = Where, Nbm = number of battery modules Cf = fuel consumption Pm = Motor Power Pe = Engine Power

Sizing Engine Initially Engine size was to deliver
57KW of the power. Values of the Engine power were varied
between 60 and 46 KW. Simulation Showed that 48KW gave the
best fuel Economy. Engine Size with 48KW was taken as
optimized result on basis of Trial and Error.

Sizing the Motor Traction Motor plays a vital role in
improving the fuel economy of vehicle. Size of traction Motor was varied from
45 KW to 60KW. Motor with 52 KW came out to be the
best size for best fuel economy. Similarly Motor 2 Size was varied from
30 to 45 KW with best size being 33KW.

Sizing the Battery Battery Series parallel Configuration
was changed to get optimized Results. The Series/parallel cell configuration
was tried and results were obtained. Battery power of 5.8KWh was optimum.
SOC Vs Time

Changing Kp and Ki Kp and Ki Are the controller gains. Individual parametric study was done. Best values were selected to get
optimum values.
