Introduction
In order to deal with the crisis of the energy, it is important to increase the popularity of
the electric vehicles. These vehicles are mainly dependent on the charging from the electrical
sources that are able to power up the engine. Lukic and Pantic (2013), have mentioned about the
fact that the electrical vehicles lost huge amount of time in the process of charging that is an
essential part of the overall process. Hence, it is important to note that in most of the occasions,
the process of wireless charging needs to be implemented in order to save the time that is
required by the electronic vehicles in the overall time that is needed in the process of charging.
According to Musavi et al. (2012), the wireless process of charging can also help to save the
time that is needed in the charging of the engine. The potential that exists in the process of
electrification of the cars can help to attract several types of research in the respective fields in
the given case. The main purpose of the research of the research is to improve upon the
commercial applicability of the wireless form of charging that can help in the process of dealing
with the issues related to the energy crisis.
The research paper of Miller et al. (2014), have mentioned about the application of
Inductive Power Transfer (IPT) that has been used successfully in many electronic vehicle
systems. This is one of the most important matters related to the powering of the electric
vehicles.
The process of wireless charging has been adopted by many of the top automobile brands
including Mercedes Benz and BMW.

RESEARCH METHODS
The basic principle of wireless charging is in this case based on most of the inductive
level of charging. Capacitive power transfer is also one of the important technological
improvements of wireless charging. The capacitive process of charging that is used in the
process of isolation is needed to deal with minimizing the cost of wireless charging. It is also
believed to be one of the convenient modes of portable electronic devices, which can be used to
power up the devices.
Wireless charging can also be the advancement in the process of autonomous charging
concept that is used by most of the luxurious automobile brands (Bi et al. 2015).
It is also based that in most cases, wireless charging is related to the bidirectional form of
charging, that is related to high effective forms of charging system, which is believed to be one
of the economic ways. Onar et al. (2013), have mentioned about the importance of efficiency due
to the fact that internal engines are able to have longer life span. With the help of the specially
designed coiled system within the internal engine, it is possible to deal with most of the cases
related to the internal engines.
It is also important to mention that wireless charging electric vehicles produce much
fewer air pollutants compared to that of traditional engines. Hence, with the help of this
mechanism, it is possible to reduce the effect of environmental degradation (Zhang et al. 2016).
In Spite of the advantages of electric cars, they have limited range due to the fact that it is not
possible to provide charge in all places. Therefore, electric cars cannot be relied upon for long
distance journey. However, with the introduction of wireless charging system, it is possible to
neutralize this limitation. This makes the electric car more users friendly and practically suitable
for all types of situation. A hybrid system that is used in the electric vehicles also enables them
to get the engine power from any source of electricity. Developers of the wireless charging

automobile vehicles have enabled them to deal with the challenges related to the developing
system.
The wireless charging is based upon the principle of electromagnetism, which enables
them to deal with the challenges related to the use of petroleum product. The type of the battery
that is used in the car is also dependent upon the type of electronic charging system that is being
implemented (Li and Mi 2015).
Another major advantage of the wireless charging technology is due to the fact that it is
possible to integrate the shape of the device within tiny wireless charging receiver. Hence, it is
possible to improve upon the overall sizing of the battery and car engine (Rajashekara 2013). It
is also possible for multiple numbers of devices to be charged simultaneously, which is believed
to be one of the effective ways of saving time. There are numerous multiple devices is charging
stations that have become popular in the recent years. As there is a minimum amount of cables
required in the overall process of charging, it is possible to save vital space within the charging
station.
On the other hand, the major disadvantages that are related to the use of wireless charging
system are due to the fact that it is related to various health concerns. The electromagnetic
radiation through which the wireless charging system is operated can cause major health issues if
they are being exposed to human for longer duration. It can also cause critical diseases like
tumour or cancer (Xie et al. 2013). In spite of the fact that wireless charging system is believed
to be one of the economic ways of powering up automobile vehicles, the initial cost of setting up
the infrastructure is generally very high. In spite of its popularity, due to the high-cost offsetting
of the infrastructure, it is not possible to commercially implement the wireless charging system.

RESEARCH METHODS
It is important for the future research has to focus on the ways to improve the efficiency of the
cost that is involved in setting up the infrastructure for the wireless charging system. It is also
important to ensure that minimum amount of harm is being caused due to the electromagnetic
radiation that is an important component of wireless charging system.
