2BATTERIES AND WIRELESS CHARGING FOR ELECTRIC CARSIntroductionDefinitionEnvironment and energy have been playing important roles in the electric transportationsystem. Electric vehicles have high flexibility and charging is not easy for them. EVs keep highbattery backup as storage for electricity to operate in a long distance. As stated by Vaka andKeshri (2017), the wireless power transfer can alienate charging system and its battery capacityis less than the storage system. Importance An internal combustion engine can run swiftly in case of a long way, however, EV needshigh power battery efficiency. This high power battery can be expensive for use; howeverwireless charging system can be cost effective for energy use and gasoline-powered vehicles.Battery needs a charging system and plug-in methods, wireless charging can be beneficial forthis. Charging cables can also bring hazards, however, in WPT, drivers just need to park theircars near a charging station and dynamic WPT will charge the cars (Li and Mi 2015). Thiswireless battery charging provides 20%more battery back-up than conductive charging. Of late,the wireless charging generates high demand in the market and researchers are working out withmagnetic resonance theory. Magnetic coupler design is important in sending the wireless powerand it is of two types, primary coupler and pick up coupler.Themes:Dynamic charging: Dynamic charging is a way to provide charging to the EV duringdriving and it can provide solutions to the range anxiety while driving. In dynamic charging,

With the use of narrow track design, construction cost can be decreased. Indesigning the track, pickup coil can cover only a little portion (Maglaras et al. 2014). Contactless power transfer: Contactless power transfer is a wireless process that can betransmitted electrical energy to the electrical devices. In case of EVs, the wireless power supplycan be categorised into two, radiative and non-radiative. Moreover, in using of non-radiativetechniques, power can be transmitted through magnetic fields by inductive coupling to wires andcoils (Qui et al. 2014). Inductive power transfer: The principle of using the inductive power transmission isdepended on the transmitting coil with another receiver coil. Two coils are coupled throughmagnetic inductors which induce through voltage. According to Miller et al. (2014), the morecoupling will be efficient, the more the power transfer will be convenient. The distance betweenratio inductors may determine the coupling strength and it can be depended on the shape and sizeof coils.In-motion wireless charging: Wireless Power transfer can be described as safe andconvenient. It is an autonomous way of charging the vehicles as it does not require bulkycharging system to carry in EVs. In-motion wireless charging helps to reduce the battery shapeand increases the battery life as a whole. Question:What are the ways to use wireless charging and battery in Electrical vehicles?
4BATTERIES AND WIRELESS CHARGING FOR ELECTRIC CARSFindings: Wireless charging is the future of WPT and it can be used by dynamic charging. This techniqueis efficient, easy-to-use and convenient charging method for giving charge to the EV. Thistechnique is helpful in the automotive industry with the beneficence of resonant magneticinduction procedure for using energy wirelessly. WPT involves disciplines of magnetic supply ofenergy and power electronics with the use of mechanical engineering and communication.However, a magnetic field is related to low density and high frequency. Circuit analysis isimportant with an analytical approach to the finite element methods. Electrification is importantin transportation as it important that it cannot be avoided due to energy-related issue. Wirelesscharging and battery is not only the concept of charging the vehicles but also it is a customer-centric operation in a daily based worked. Further, wireless system provides the benefits ofrecharging in the parking space. It provides the advantage in charging the battery in a consistentway without the complex system. The users need to have the plugs, cables; adaptors and it canmultiply the charging facility with gadgets. The system of little and often charging system daysare gone and the people are using this in forefront trends. An EV can be charged at anywhere andit cannot be possible at wired charging (Yilmiz and Krein 2013)). Vehicles to grid power transferare becoming popular with bi-directional converters that have inductive links. It is important tohave the converters and controllers intact with the presence of coils and wires from AC supply ofenergy.Conclusion Different technologies can be taken to use of wireless power transfer to the EVs, howeverinductive power supply with magnetic use can be helpful and it is cost effective. Coils and wirescan be used to improve the efficiency. Various types of compensation topologies can be used that

Using of wireless charging is nowadays is important as itprovides relief from the burden of equipment with promoting the green energy. Moreover,conducting charging is related to the use of cables and wire, wireless charging is the new trend inthe automotive industry.
