2. WHY ELECTRIC VEHICLES?

3. Petrol, Diesel and gas
vehicles:
 non renewable
resources(scarce)
 Depending on
foreign oil
 High cost
 Less reliable
 Oil spills problems
EV’s batteries:
 Solar and wind
energy can be
utilized
 Domestically
generated electricity
 less cost
 More reliable
 No oil spills problems
We can charge them in our home itself

4.  Batteries need to be charged.
 Car can not be used when batteries are being
charged.
 They can only go Less Kms between charges.
 Battery disposal needs to be carefully managed.
 Charging stations required=>load and their centers
vary
 Electric Grid changes required.

5.  Battery electric vehicles: (BEV)
works on battery .
 Plug in hybrid electric vehicle(PHEV):
Battery, electric drive train and internal
combustion engine
 Hybrid electric vehicle: Battery and internal
combustion engine

6. Hybrid electric vehicle

7. What is a Hybrid Electric Vehicle?

10. LITHIUM-IONBATTERY

11.  Regenerative braking : Converting motor
to generator (saves energy)
 Plugging : Reversing the armature
terminals .
 Dynamic Braking :Reversing supply and
adding resistance
