The invention discloses battery charge and discharge simulation test equipment developed for a battery system of a new energy electric vehicle, and belongs to the technical field of battery detectionequipment. The battery charge and discharge simulation test equipment developed for the battery system of the new energy electric vehicle comprises a rotary motor and a storage battery placing box, athird rotary shaft is connected to the rotary motor through a convey belt, a rotary disc is fixedly connected to two ends of the third rotary shaft, a first connecting rod is rotatably connected to afirst connecting shaft, the first connecting rod is connected with a second connecting rod through a second connecting shaft, a fixing connecting plate is fixedly connected to the upper end of the second connecting rod, a sliding plate is slidably connected to the fixing connecting plate, and the storage battery placing box is fixedly connected to the sliding plate. According to the battery chargeand discharge simulation test equipment, the moving states when the new energy vehicle bumps up and down, turns left and right, drives normally, in brakes are stimulated, so that the damage situationof a lithium battery after moving can be detected, and the service life of the battery is convenient to judge.
