3. • In contrast to fuel-powered vehicles,
electric vehicles have to be recharged
almost every day as the energy content of
vehicle batteries is much smaller than the
energy content of fuel tanks.
• To introduce new electric vehicles in the
market need An adequate charging
infrastructure is thereby important
• Rang of adequate charging infrastructure is
broad.
Infrastructure location: private or public.
Charger hardware: unidirectional or
bidirectional.
Charging power: slow or fast charging.
Charging plug: one-phase plug without
communication or combined ac/dc plug
with communication.

the road by the year
2030.
To keep fuel pricing
under control.
To reduce Range Anxiety
of EV owners.
Maximizing use of EVs
on the road.
India needs good infrastructure to accommodate the following needs and fast charging
can fill these needs.
“Modeling & Simulation of Electrical Vehicle DC CC-CV Fast Charger by Mrs. Sonali A. Fapal”

11. Findings
11
Higher losses in battery by the Fast charger and in battery (I2R)
Only 70 to 80% battery can charge in fast charging
As C rate of charging is increases life of battery get decreases
Due to high ampere current requirement charger needs thicker and rigid cables are
needed which are not good for handling due to less flexibility.
