The invention relates to the technical field of stacking machines, in particular to a lifting control device of a pure electric stacking machine and the stacking machine. The control device comprises a lifting hydraulic mechanism and a lifting electric control mechanism; the lifting hydraulic mechanism comprises a lifting oil cylinder, a one-way valve and a two-way hydraulic pump; the one-way valve is arranged on a bypass between the lifting oil cylinder and the two-way hydraulic pump, and the lifting oil cylinder, the one-way valve and the two-way hydraulic pump are connected through oil pipes or integrated valve blocks. The lifting electric control mechanism comprises a super capacitor, a battery pack, a direct current bus, a lifting motor controller and a permanent magnet synchronous motor; the lifting motor controller is connected with the permanent magnet synchronous motor; the permanent magnet synchronous motor is connected with the bidirectional hydraulic pump; the lifting motor controller is connected with the one-way diode and the two-way DC/DC converter through a direct-current bus; the unidirectional diode is arranged between the battery pack and the direct current bus, and the bidirectional DC/DC converter is arranged between the super capacitor and the direct current bus; the output voltage threshold of the bidirectional DC/DC converter close to the DC bus side is higher than the output voltage value of the battery pack.
