“…Under the condition that all sellers meet the requirements, the time cost of each decryption operation is O(log n) corresponding to I*J*k calculation results. After decryption, we execute the matching algorithm, calculate the matching index wij for M users who satisfy user I, and then get the minimum matching index wijmin for user I after sorting it, with the time cost of j*O (1). At this time, the buyer I and the seller J are successfully matched.…”

With the development of electric vehicles, more and more electric vehicles have difficulties in parking and charging. One of the reasons is that the number of charging piles is difficult to support the energy supply of electric vehicles, and a large number of private charging piles have a long idle time, so the energy supply problem of electric vehicles can be solved by sharing charging piles. The shared charging pile scheme uses Paillier encryption scheme and improved scheme to effectively protect user data. The scheme has homomorphism of addition and subtraction, and can process information without decryption. However, considering that different users have different needs, the matching is carried out after calculating the needs put forward by users. This scheme can effectively protect users' privacy and provide matching mechanisms with different requirements, so that users can better match the appropriate charging piles. The final result shows that its efficiency is better than the original Paillier scheme, and it can also meet the security requirements.

In recent years, electric vehicles are the large-scale spread of the transportation field has led to the emergence of brushless direct current (DC) motors (BLDCM), which are mostly utilized in electrical vehicle systems. The speed control of a BLDCM is a subsystem, consisting of torque, flux hysteresis comparators, and appropriate switching logic of an inverter. Due to the sudden load torque variation and improper switching pulse, the speed of the BLDCM is not maintained properly. In recent research, the BLDC current control method gives a better way to control the speed of the motor. Also, the rotor position information should be the need for feedback control of the power electronic converters to varying the appropriate pulse width modulation (PWM) of the inverter. The proposed optimization work controls the switching device to manage the power supply BLDCM. In this proposed self-ameliorate soft switching (SASS) system is a simple and effective way for BLDC motor current control technology, a proposed control strategy is intended to stabilize the speed of the BLDCM at different load torque conditions. The proposed SASS system method is analyzing hall-based sensor values continuously. The suggested model is simulated using the MATLAB Simulink tool, and the results reveal that the maximum steady-state error value achieved is 4.2, as well as a speedy recovery of the BLDCM's speed.

“…The charging system placed onboard [7] is trending these days for EVs, which is made possible because of growing technology in power electronics in the automotive sector. The battery system which is installed on the board of EV is charged [8], [9] from the grid (AC) source after being converted to DC type through an AC-DC converter. The battery supplies the power to the motor and the mechanical output of the motor through the gear system is connected to the wheel of the EV.…”

<span lang="EN-US">Extinction and the emission of greenhouse gases from fossil fuels led the field of energy studied took a revolutionary turn towards non-conventional natural sources achieving zero-pollution power. Electric vehicles (EVs) are trending in this new era to reduce the global warming. Due to limitations in storage systems, electric vehicles are not much popular but to reduce the pollution from vehicles, EVs are in must condition and recommended for (public/personal) transportation. EV (battery) is charged through a DC source (converting the available AC supply to DC). The conversion process diminishes the input source power factor and is a worrying factor. This paper addresses the power factor issue while charging the battery of EVs. The paper focuses on maintaining the unity power factor on the source side while charging the battery of the EV from AC-DC conversion. The model is developed and the results are discussed (for three different battery levels) using MATLAB/Simulink software.</span>
