ELECTRIC VEHICLE (EV)
An electric vehicle is a vehicle that uses one or more electric
motors for propulsion …
It can be powered by a collector system ,with electricity from
extravehicular sources or it can be powered autonomously by a
battery

History of e-vehicle
• First model electric vehicle is attributed by
many people
• In 1828,hungarian priest and physicist anyos
jedlik invented early type of electric motor
and created a small model car powered by
his new motor
• In 1832 to 1839 ,scottish inventor robert
anderson also invented a crude electric
carriage
• In 1835 professor sibrandus stratingh ,the
netherlands and his assistant chistopher
becher also created a small scale electric
car, powered by non rechercable primary
cells
• The first electric car in the us was
developed in 1890-91 by william morrision
• The first electirc vehicle in india was a
three wheeler,invented by scooter 's india
pvt ltd,it was named VIKRAM SAFA

Electric vehicle concept
EV is a road vehicle based on modern electric propulsion consisting of electric
machine ,power electronic converters ,electric converters,electric energy
sourcesand storage devices and electronic controllers
EV is a broad concept ,including BEV, HEV, FCEV,etc...
Regenerative breaking is possible in EV's
EV is not only just a car but a new system for our society's clean and efficient road
transportation
EV is an intelligent system which can be integrated with modern transportation
networks
EV design involves the integration of art and engineering ;

Comparisonwith
internalcombustion
enginevehicle
• Electric cars are generally more expensive
than gasoline cars. The primary reason is
the high cost of car batteries running costs
and maintenance
• Electric cars produce no pollution at the
tailpipe, but their use increase demand for
electricity
• Internal combustion engines are relatively
inefficient at converting on-board fuel
energy to propulsion as most of the energy
is wasted as heat as compared to electrical
engines
• Electric cars produce less roadway noise as
compared to vehicle propelled by internal
combustion engine
FUTURE
The future of battery electric vehicle depends primarily
upon the cost and availability of battery with high specific
energy, power density, short charge time and long life ,as
all other aspects such as motors, motor controllers with
internal combustion engine components
I. Li –ion
II. Li –poly
III. Zic air batteries
have demonstrated specfic energy high enough to
deliver range and recharge times comparable to conventional
vehicle.

Future of
e-vehicle
in India
• About two in every 100 cars sold today are
powered by electricity
• The global EV fleet totaled 8.0 million with
EVs accounting for 1% of the global vehicle stock and
2.6% of global car sales
• India is among the handful of countries that
supports the global EV30@30 campaign ,which aims
for at least 30% of vehicles sales to be electric by
2030
• It is estimated that by 2020-30
India's cumulative demand for batteries would be
approximately 900-1100 G wh
• The ministry of power has prescribed at least
one charging station to be present in a grid of 3 km
and at every 25 kms on both sides of the highways
• India's transport sector besides ,complying with
its target of net zero emissions by 2070
