Abstract

The present disclosure relates to the technical field of lift trucks, and in particular, to an energy control method and system of a lift truck. The method includes the following steps: step 1, putting the lift truck in a working state, and downwards closing a work platform at a high place, wherein hydraulic oil in an upper lifting oil cylinder and hydraulic oil in a lower lifting oil cylinder start to flow back into a oil tank; step 2, driving a hydraulic element to rotate anticlockwise in the back flowing process of the hydraulic oil, wherein the anticlockwise rotation of the hydraulic element drives a motor to rotate anticlockwise to generate a reverse electromotive force, and the reverse electromotive force is rectified to output a direct current for energy recycling.
