6. A REVIEW ON AUTOMATIC ELECTRIC VEHICLE CHARGING STATION WITH BILLING SYSTEM

The market for electric vehicles has grown with each year, and EVs are considered to be a proper solution for the reduction of pollution. So far, not much a ttention has been given to the use of electric vehicles for public transportation, such as taxis and buses. However, a big introduction of electric taxis and electric buses could generate issues in the area. The challenges are different from those of priva te electric vehicles, as their required load is significantly greater. Recent years have seen the start of research on these issues. Electric vehicle technology offers numerous benefits, but it also has several drawbacks, including issues with battery charging, increased electric charge accessibility at charging stations, and battery life evaluation. In this research, a smart switching mechanism for electric vehicles is suggested. An ultrasonic sensor is used to detect vehicles at the charg ing station. The charging system is discussed in the part that follows the detection of the vehicle battery voltage. The suggested system offers a highly efficient, cheaper, and environment-friendly solution for charging electric vehicles. In order to meet the need of an ever growing demand for electric vehicle charging infrastructure, a software based electric vehicle charging system has been built. It has the ability to optimally schedule charging in order to safely maximize the use of available resources for charging electric vehicle and thereby maximizing the number of electric vehicles that can be connected to the pantograph while enhancing pant ograph stability I. I NTRODUCTION Because of its clever, costeffective, and environmentally beneficial services, electric vehicles have gained the at tention of users. Due to the extraordinary wonder of the steady growth in urban populations, it is now crucial at the metropolitan area provide trustworthy solutions. [1] One of the contributors to this ecological instability is the transportation industry alone, which accounts for nearly a quarter of global greenhouse gas emissions.
