The invention discloses a detection method, equipment and medium for a
new energy high-power direct-current charging
pile, and relates to the technical field of charging
pile stability detection, and the method comprises the steps: controlling a direct-current
electronic load to generate a load disturbance
signal at N characteristic working points, collecting instantaneous value change data through a
broadband data collection center, and calculating the stability of the charging
pile according to the instantaneous value change data; and based on the dynamic load disturbance
signal and the instantaneous value change data, calculating the
pulse response characteristics of the to-be-tested DC charging pile at the N characteristic working points through a
correlation function analysis method, constructing a
dynamic impedance characteristic model, and based on the safe working area three-dimensional boundary map, the
electric energy quality indexes of the N characteristic working points and the
dynamic impedance characteristic model, calculating the
dynamic impedance characteristic of the to-be-tested DC charging pile. And evaluating and diagnosing the comprehensive performance of the
direct current charging pile to be tested. According to the
direct current charging pile comprehensive performance detection method based on dynamic load disturbance, accurate
physical examination of the overall performance of the charging pile is achieved, and the detection depth, precision and
predictability are improved.
