Abstract
• This study especially focused on Wireless charging system for Electric vehicle using Supercapacitor, which
uses magnetic resonance coupling.
• Considering future wireless vehicle stationary and dynamic charging facilities, supercapacitor could be an
ideal device to store a reasonable amount of electrical energy for a relatively short period of time.
• The prototype system includes all the major functional components for an electric vehicles and wireless
charging system including coils for energy emitting and receiving, a FPGA PWM input generation board,
high frequency inverter and rectifier circuits, an on-board supercapacitor module, sensors for SOC level
measurement and charging position detection, etc…
• Wireless electric transmission refers to wireless electric transmission between power supply and electric
vehicles.
• The supercapacitor is at the core of the energy storage system, and the self-starting circuit is used to supply
energy without complicated power supply circuit. Compared with lithium batteries, supercapacitors have
significantly improved the performance of overcharging, over discharging, stability and safety.

Introduction
• After the oil crisis broke out, people realized that energy is a limited resource. In addition, many
traditional fuel vehicles not only consume oil resources but emit more exhaust gases like carbon oxides
and nitrogen oxides, the greenhouse effect is deteriorating the living environment of human beings.
• Since beginning of the new century, energy crisis and environmental crisis have become two major
focuses of global attention. Their forms have endangered the survival and prosperity of human beings,
which is thought-provoking.
• To achieve sustainable development and implement the concept of green development of ecological
civilization, and to get rid of the predicament faced by traditional fuel vehicles, we need to seek new
ways of development.
• One of the most important ways is to develop new energy vehicles, including pure electric vehicles and
hybrid vehicles.
• It is self-evident that in the next few years, the global electric vehicles and supporting charging facilities
will mushroom to user in the golden age of their development.

1. Coils
there are three types of coils in the wireless charging
system, namely one emitting coil, two resonating
coils, and one receiving coil, respectively. The
resonating coils work as an isolated transformer to
transfer the electromagnetic energy from one
winding to another using magnetic resonance
coupling which is intended to extend the transfer
distance to a considerable level, such as 10cm, while
the conventional magnetic coupling without
resonance can only reach a transfer distance less
than 1cm without sacrificing the transfer efficiency.

Conclusion

• From this data, we can see that in the power supply, especially he short-distance acceleration stage. The
car with super capacitor is faster, while the lithium battery car is better in endurance. We use
supercapacitors as auxiliary power supply to provide enough start or sprint energy for the car, and lithium
batteries as the main driving energy, so that the car can travel farther in the course of measurement by
providing the same electric energy.
• In the field of electric vehicles, radio charging technology will develop at a high speed. Radio charging
technology will solve the dangerous problems such as line aging and fire. At the same time,
supercapacitor as an auxiliary power supply will greatly shorten the charging time and improve the
endurance ability.
