Abstract: An Electric vehicle can be future trends Because of their rapid growth, electric vehicles (EVs) are expected to play a significant role in the global transportation sector's energy transition. The integration of high-level EVs into the electrical grid will present several difficulties for standards, safety, planning, operation, and stability of the power system. To meet the expected charging solutions for EV batteries and to enhance ancillary services, the widespread adoption of EVs necessitates research and development of charging systems and EV supply equipment (EVSE). In order to improve desired charging efficiency and grid support, find a remedy for any negative effects, and hasten EV adoption with sophisticated control strategies, it is critical to analyze the current state of EV charging technology. An extensive review of EV charging technologies is presented in this publication. worldwide standards, EV charging station layout, and EV charging system power converter combinations. To achieve optimal operation and improve grid support, the charging systems need a specific converter architecture, a control strategy, compatibility with standards, and grid codes for charging and discharging. An overview of several charging methods is assessed, including AC and DCbased charging station layouts, onboard and off-board chargers, and AC-DC and DC-DC converter configurations. A presentation of contemporary charging systems that incorporate renewable energy sources is also included to show the power architecture of contemporary charging stations. The research's future path is finally summed up by EV charging trends and problems, as well as grid integration issues.
