Description

Electric Vehicle Charger Test System and Method The present invention relates to an electric vehicle charger test system and method, and provides an electric vehicle charger test system and method that includes a portable device capable of testing a charger capable of slow charging of an electric vehicle and capable of verifying the test results. Charging electric vehicles requires high safety standards because it uses high voltage and current. Additionally, if the charging speed of an electric vehicle charger is inconsistent, problems such as degradation of the electric vehicle's battery performance may occur. Furthermore, if the voltage or current of the electric vehicle charger is not output normally, risks such as overvoltage, overcurrent, or leakage may arise, and a malfunction of the electric vehicle charger could lead to major accidents resulting in casualties, such as fire or electric shock. Accordingly, tests on electric vehicle chargers must be conducted at regular intervals to verify their performance and safety. For testing conventional electric vehicle chargers, actual electric vehicles were used and directly connected to the chargers to conduct tests in real-world charging environments. Additionally, an expert separately recorded the information generated during the test to compile a test report. Currently, tens to hundreds of thousands of electric vehicle chargers are installed nationwide, and demand is expected to increase further in the future. However, the existing testing methods and systems described earlier present a problem in that it is difficult to test all chargers within the target time and to collect and organize the results.
