<![CDATA[The increasing adoption of electric vehicles (EVs) has created a growing demand for effective, efficient, and safe battery charging systems. One important aspect of the charging process is the relationship between charging power, charging time, current, and battery temperature. This study aims to analyze the differences in battery charging characteristics between normal charging and fast charging and to identify the influence of charging power and current on charging time and battery temperature. A descriptive research approach was employed, supported by a literature review and electric vehicle charging measurement data. The analyzed parameters included battery capacity, voltage, current, charging power, charging time, and battery temperature. The analysis results indicate that increasing charging power and current can reduce the time required to charge the battery. The test data showed charging power ranging from 2.76 kW to 11.04 kW, with charging currents of 12–48 A at a voltage of 230 VAC. The temperature analysis indicates that higher charging currents need to be supported by adequate thermal management because battery temperature may increase during the charging process. Therefore, charging effectiveness should not be evaluated solely based on charging speed but should also consider temperature, safety, battery condition, and thermal management. Further research using controlled experimental measurements is required to obtain a direct comparison between normal charging and fast charging.]]>
