technical field [0001] The invention relates to a power supply system, in particular to a power supply system used in a lifting device, which can recover part of the potential energy released by the lifting device, convert the part of the potential energy into electric energy for reuse, and achieve the effect of energy saving. Background technique [0002] Lifting equipment is an indispensable part of today's types of building structures, especially in cities where building land is generally insufficient, and buildings have to increase their height to achieve a higher volume ratio. Therefore, whether it is carrying people or objects, all kinds of lifting equipment can be seen everywhere in daily life, and the operation of lifting equipment consumes energy is inevitable, so the following will briefly describe the operation and energy consumption of known lifting equipment relationship.

AI Technical Summary

Problems solved by technology

[0008] Generally speaking, although the capacitor is relatively simple in manufacturing process, its energy storage capacity is relatively small due to its low energy storage density, and it can only be used as short-term energy storage.

The traditional battery mainly uses chemical energy to store energy, so its energy storage density is significantly better than that of general capacitors, and it can be applied to various power supply devices. However, the disadvantage is: the instantaneous power output it can generate It will be limited by the chemical reaction rate, so it cannot charge and discharge quickly or perform high power output, and the number of charge and discharge is limited, and it is easy to cause various problems when overcharged; for example: the batteries currently used, although advertised as reusable , but still has its lifetime limit

In the case of repeated charging and discharging or long-term non-use, the capacity of the battery will decrease and it will be easily damaged. The reason is that the battery uses chemical energy to convert into electrical energy. When the activity of all the compounds is used up or nearly used up, new chemical reactions can no longer be carried out, which leads to the aging of the battery and the end of its service life

The supercapacitor is a component between the battery and the capacitor, also known as the electrical double-layer capacitor (Electrical Double-Layer Capacitor), because it uses part of the physical energy storage and part of the chemical energy storage structure at the same time, so it has more energy than ordinary capacitors. Large capacity, but its disadvantages are: due to the chemical characteristics of the chemical material, it is easy to have the leakage defect of the battery, and in addition, due to the phenomenon of fast discharge due to some physical characteristics, there are many problems in this way. The phenomenon of running out of power soon, can not achieve effective power storage function

Even, supercapacitors have low withstand voltage and large internal resistance, so they cannot be used in AC circuits, and if they are used improperly, electrolyte leakage will occur. Due to the inherent characteristics of supercapacitors, the power consumption is too fast. It will be necessary to recharge it frequently, making it unsuitable as a primary power supply source

[0009] Therefore, the above-mentioned known energy storage elements cannot simultaneously achieve the advantages of long service life (high charge and discharge times), high energy storage density, instantaneous high power output, and fast charge and discharge required by lifting equipment.

Therefore, because the known capacitors and batteries have an energy storage density that is not enough to store enough electric energy to supply the lifting equipment under an ideal weight, in other words, the known capacitors or batteries, in The application of this situation will not have acceptable economic benefits, because if it is desired to store sufficient electrical energy in this case to be recycled and reused, an energy storage device formed with a known capacitor or battery will have The astonishing weight and volume, as a result, has become a practical obstacle for the lifting equipment (in order to be able to bear the extra weight and volume, the main structure and design of the lifting equipment must be reconsidered), Therefore, the advantages brought by energy recovery will be greatly reduced
