The invention relates to an elevator energy storage device. The elevator energy storage device is provided with an elevator shaft. A cross beam is arranged on the elevator shaft. A traction system is arranged on the cross beam. The two ends of the traction system are provided with an elevator car and a counter weight respectively. The bottom of the elevator shaft is provided with a generator set. A tensioning rope is wound around the generator set. The generator set is connected with a capacitor module. A voltage limiting circuit is arranged between the generator set and the capacitor set. The voltage limiting circuit is connected with a warning device. The elevator energy storage device has the advantages that as the tensioning rope is arranged at the bottom of the elevator car and the bottom of the counter weight and wound around the generator set, the generator set can be started through relative movement of the elevator car and the counter weight, energy produced by the generator set is stored into the capacitor module, and electricity in the capacitor module is transmitted to electric equipment; the elevator energy storage device is simple in structure, elaborate in design and low in cost.
