The invention relates to a system and method for testing charging control response time of an electric vehicle charger. The testing system comprises a direct-current source, a direct-current load, a storage battery management simulation system, an oscilloscope and a main control computer, wherein the direct-current source and the direct-current load are used for simulating characteristics of storage batteries for an electric vehicle, the storage battery management simulation system is used for simulating a storage battery management system in the electric vehicle and is in communication with a tested charger control system for conducting communication data exchange, the oscilloscope is used for simultaneously recording a charging current output by the charger and a communication message between the charger and the electric vehicle, and then the charging control response time of the charger is calculated. By means of the system and method, the charging control response time of the electric vehicle charger can be objectively and accurately measured, influences of human factors are overcome, test results are scientific, the response capability and the output performance of the charger can be accurately reflected through the test results, and data supports are provided for objectively evaluating compatibility, interconnection and intercommunity between the charger and the electric vehicle.
