Week 2 Session 7

1)Compare the different architectures of HEV. Discuss the pro's and con's?

Sol:-

a)EV:-

EVs, confusingly also known as BEVs (battery electric vehicles), have no internal combustion engine to convert gasoline into propulsion power. Instead, they run solely on electricity from one or more large batteries.

Pros:-i)They Are Having Less Running & Maintainance Cost ,due to less no. of moving Parts.

ii)They reduce Carbon Emissions.

Cons:-i)These Type of Vehicle lacks in Range extension.

ii)Servicing Facility Of such Vehicle Is too difficult to Adopt.

b)HEV:-

These vehicles perfected the art of combining an internal combustion engine with an electric-powered motor, switching between the two to improve fuel economy.

Pros:-i)Range of Such Vehicle is More than other convectional vehicles.

ii)They are more Environment Friendly

Cons:-i)Maintenance can be expensive (when it's needed)

ii)They still produce fossil fuel emissions.

c)PHEV:-

Essentially a combination of an EV and an HEV, a plug-in hybrid electric vehicle (PHEV) is built to run on both gas and battery power. The key difference is that the power comes from plug-in chargers, making them more like an EV.

Pros:-i)Less cost of driving

ii)Reuce carbon Footprint

Cons:-i)High Upfront Cost

ii)High Complexity
