The invention discloses a multiple-working-condition automatic testing experiment system of electric vehicle charging equipment, belonging to the field of a new energy vehicle. The system is formed by an industrial computer and software system, a voltage and frequency controlled AC power supply unit, a load unit, a high precision measurement unit, temperature and humidity adjusting equipment, and a protection and control unit. The system is used for testing an electric vehicle vehicle-borne charger and a non vehicle-borne charger. According to the system, grid voltage and frequency static deviation, voltage and frequency fluctuation, a power battery pack with different rated parameters and different temperature and humidity conditions can be simulated to test the communication performance, output stability, output accuracy, protection limit characteristic, temperature rise characteristic, current harmonic wave, voltage fluctuation and flicker, three-phase unbalance, power factor, efficiency and abnormality response ability of experiment charging equipment, certain data support is provided for the research of electric vehicle charging equipment technical specifications, the whole process automatic control of the testing is realized, and the testing efficiency is greatly improved.
