Project 2

AIM :

The aim of the project is to understand the functionality of a P1 hybrid and be able to model it.

Objectives:-

The task of this project is to quantify the improvement in fuel economy numbers for the hybrid vehicle (kmpl), compared to the conventional vehicle, on the urban cycle (UDDS) and highway cycle (HWFET).

THEORY :

P1 MILD HYBRID ELECTRIC VEHICAL :

he P1 features a 3.8L V8 TWIN TURBO CHARGED ENGINE WITH A 132 KW ELETRIC MOTOR. This hybrid power plant generates 903 bhp and 664 lb-ft of torque. Those specs allow a McLaren P1for sale to go from 0-62 mph in just 2.8 seconds.

EXAMPLE ;

• Honda Insight Hybrid 2009
• Mercedes Benz S400

Hybrid modes :

dle Stop & Start
Moving Stop & Start
Engine load shift
Torque assist (fill)
Torque boost
Sailing / Coasting
Energy recuperation
Brake regeneration

Advantages:

Low cost of integration.
Air or liquid cooled electric machine.
Integrated inverter (with electric machine).
Size modularity for the electric machine.
Speed / torque ratio possible between electric machine and ICE results in lower Power demand from the electric machine.

Disadvantages:

Limited torque capacity due to belt drive.
Energy recuperation affected by engine friction losses.
