This invention relates to the field of clamping control, and more particularly to an active voltage overshoot clamping system for battery testing equipment. The invention comprises a clamper, a feature memory, a filter, an interference analyzer, a predictor, and a clamping controller. It uses prior data—including the test step execution sequence, time-domain mapped overshoot characteristics, and the attribute characteristics of the tested battery—to filter out overshoot step combinations and construct a drift feature pool specific to each combination. Subsequently, when the test equipment pre-executes the overshoot step combination, the overshoot occurrence is predicted, and a clamping optimization strategy is determined based on the adaptability of the drift feature pool, adjusting the duty cycle upper limit in advance. This invention utilizes prior data to summarize overshoot step combinations and considers the differences in the attributes of the tested battery to construct a drift feature pool. This allows the system to perform clamping control adaptably to the attributes of the tested battery under different overshoot step combinations, improving the accuracy and reliability of overshoot voltage suppression.
