Charging Automation for Electric Vehicles: Is a larger Battery

1Abstract—Electric Vehicle Wireless Charging approach is
revolutionizing the changes in the electric vehicle industry.
Existing batteries for electric vehicles are designed to power the
drive for a range of at least 100 kilometres. The battery capacity
must be increased beyond hundred kilometres, which in turn
increases electric vehicle costs and charging time but with long
term advantages. The battery size can be increased for the same
travel range with Dynamic Wireless Charging, thereby allowing
for full sufficiency and performance.
Dynamic Wireless Electric Vehicle Charging System contains
a number of inductive coils embedded on the road. The number
of inductive coils selected depends on the length of the track.
Each inductive coil acts as a transmitter and high frequency
resonant inverter excites the transmitter coil terminals for
wireless power transfer. This paper gives a solution to the
capacity of batteries needed for an electric vehicle. The size of
battery must be sized based on available infrastructure for a
specified region.

I. INTRODUCTION
Here has been growing interest in electric vehicles (EVs)
owing to calls for environmental sustainability in
vehicles[7]. Wireless charging of cars while in motion relates
to capacity of charging a car with resonant inductive energy
transfer while it is in movement. The technique is
accomplished by installing power coils in the highway and
including a pick-up coil inside the car, to achieve maximum
power transfer, the vehicle must be along the path in which the
coils are installed. Theoretically, wireless charging of vehicles
while in motion will solve some Electrical Vehicle (EV)
battery issues. This is by providing a chance to analyse various
capabilities of different batteries and enabling the use of lower
batteries that decrease costs and weight, but application will
be restricted by the accessibility of charging infrastructure,
which in turn is restricted by its costs. Null tailpipe emissions
have a plug-in or battery-powered electrical systems that
enhance sustainability and the environment of urban regions.

battery. The hypothesis for the research is that the size of
batteries will depend on the route of the bus and cost of
installing continuous wireless charging. Cars which operate on
long routes needs large battery banks, while small batteries are
good for city operating buses. The effective convergence of
new technology will involve low-cost and fully autonomous
electric vehicles (EVs). These characteristics can be achieved
by wireless charging. Transportation by electric vehicles will
contribute to the reduction of greenhouse gases and cope
with increasing oil rates. Electrical vehicles require a broad
range of charging infrastructure to be set up to encourage
adoption in green energy environment. Wireless power plug-in
electrical charging vehicles can serve as a potential alternative
technology for fixed charging points.
II.LITERATURE REVIEW
The performance and drive range of wireless charging
vehicles has greatly improved over time. Commercially
reliable electric vehicles are already available in the market,
with the number of EVss on the highway quickly increasing.
Despite the fact that most current EVs are charged by
electrical cables, businesses such as Tesla, BMW and Nissan
have begun developing wireless charged EVs that do not
require large wires [1]. The wireless (inductive) connection
efficiently prevents sparking over plugging / unplugging
instead of physical cable connection. In addition, wireless
charging opens up fresh vibrant charging options–charging
while driving [4].
Energy storage capability is an increasing problem,
companies have resort to clean energy, most clean energy
requires storage components. advances in backup systems are
needed to addres the renewable technologies ' supply
reliability problems. This trend is also followed by EV's on-
board battery storage, hence the absence of battery capacity
and advances in energy density has the ability to limit the
ongoing growth and market take-up of EVs [7]. Advances in
battery backups have a huge significance to renewable energy
technologies, this are also felt in electrical vehicle industry[6].
There are a range of EV backup systems under production
(provided in table below), but while Lithium -Ion batteries
have reduced specific energy, their elevated s power,
efficiency and cycle life make them the most appropriate
traction battery technology [2]. EV battery expenses are range
between $227/kWh but continue to decline as technology and
large productions, with Tesla reporting $190 per kWh battery
costs [2]. Moreover, the traction battery energy to mass ratio,
