Description

Electric Vehicle Charging System and Server for Supporting Electric Vehicle Charging The present invention relates to an electric vehicle charging system and a server for supporting electric vehicle charging, and more specifically, to an electric vehicle charging system and a server for supporting electric vehicle charging that can supply emergency power to an electric vehicle using a drone equipped with a battery. Consumer interest and demand for electric vehicles are increasing as they emerge as the most effective alternative for reducing greenhouse gas emissions and improving energy efficiency. Unlike conventional internal combustion engine vehicles, electric vehicles (EVs) require components such as batteries, electric motors, inverters, converters, and Battery Management Systems (BMS). Rechargeable secondary batteries are used for electric vehicles. Secondary batteries, which can be recharged and reused after use, are manufactured into battery modules or battery packs by connecting multiple battery cells in series according to the output capacity required by the device, and are used as power sources for various devices. Secondary batteries are used in a wide range of fields, from small high-tech electronic devices such as smartphones to electric bicycles, electric vehicles, and Energy Storage Systems (ESS). A prerequisite for the widespread adoption of electric vehicles is the establishment of charging infrastructure, including electric vehicle charging stations. Electric vehicle charging stations generally receive power from the power grid or solar power generation facilities to charge electric vehicles. Recently, considering power variability due to weather and time of day, electric vehicle charging stations have emerged that store grid power or solar power in an ESS and utilize the ESS as an additional power source to charge electric vehicles. When the State of Charge (SOC) of an electric vehicle decreases, the vehicle must move to an electric vehicle charging station to charge. However, if it is impossible to reach an electric vehicle charging station due to the remaining SOC, support is needed to extend the driving range sufficient to reach the charging station.
