Abstract
Fast charging technology is attracting attention due to the increase in the use of batteries such as EV (Electric Vehicle), LEV (Light Electric Vehicle) and ESSs (Energy Storage Systems). Fast charging of the battery has problems such as fire, heat, and performance degradation of the battery. In the case of fast charging, a large current is applied to the battery to charge it. For this reason, information of battery voltage, battery current and temperature is important when charging a battery. Excessive current, overvoltage, and overheating beyond the standard value can cause deterioration of battery performance and a direct cause of fire. Therefore, the condition of the battery must be operated in the condition that meets the battery standard. To overcome these problems, we are trying to solve problems such as battery overheating and accidents by applying real-time monitoring technology, User Mode and Auto Control Mode. In this paper, we propose a real-time monitoring system based on the PHPOC Wi-Fi Shield. It operates to efficiently manage the charger and battery status based on real-time data, and is verified through real-time monitoring of the proposed system.

Summary
The problem of environmental pollution and air pollution is a key issue. Vehicles using fossil fuels are a major cause of environmental pollution due to exhaust gas. In order to efficiently manage the battery, it is necessary to check the charging current and voltage status of the battery in real-time. Depending on the temperature condition of the battery, an appropriate current control system can solve the heat generation problem. In the case of EV and LEV chargers as in [14,15], the user cannot check the state of charge of the battery It is not easy for the user to efficiently manage the battery. A monitoring system is proposed to efficiently manage the temperature, charging voltage, and current of the battery in real-time. We propose efficient management of fast charging systems based on a real-time monitoring system.
