ABSTRACT
Due to environment and fuel resource concerns, there is a growing demand for EV’s.
Development of PE technologies for EV’s assume importance in this content.
WHY HYBRIDS?
Increase in population and decrease in natural resources like conventional fuels.
Availability of petrol and diesel are decreasing due to over usage.
Cost of fuel rises.
To Reduce environmental pollution.
INTRODUCTION TO HYBRID ELECTRIC VEHICLE
A vehicle that combines two are more sources of power that can directly or indirectly provide propulsion power is a hybrid.
A HEV is a type of hybrid vehicle and electric vehicle which combines a conventional ICE propulsion system with an electric propulsion system.
HEV OPERATION MODES
Electric drive mode
Hybrid/electric assist mode
Idle stop mode
Regenerative braking mode
Engine starting mode
Battery charging mode
APPLICATIONS
These are more efficiently used in city drives where traffic is more.
These are also used in military cars.Some of hybrid electric vehicles are Toyota Prius, Honda Insight.
