Super Capacitor Module Type Application
Since the working voltage of a super capacitor is not high, generally only 1V-4V, the commonly used single super capacitor voltage specification is generally 2.7V, and in practical applications often require 16V, 48V, 54V, 75V, 125V or higher voltage in order to meet the use of these devices. Most of these equipment are wind power generation, automotive HEV, military starting power supply and microgrid equipment, etc. In order to meet the requirements of the use of these equipment, super capacitor modules have emerged.

1. Can supercapacitors replace lithium batteries?
Supercapacitors have unparalleled advantages that lithium batteries don’t have. For example it can store a large amount of electricity in a small volume; its long cycle life enables it to be repeatedly charged and discharged thousands of times; short charge and discharge time; good ultra-low temperature characteristics; high current discharge capability, etc. However, it is still too early to say that super capacitors can replace lithium batteries. Because current production of super capacitors is technically incomplete and the production cost is high. In addition, its energy density is low and cannot store more energy per unit volume. Another point is that it is not resistant to high temperatures and cannot be placed in a humid environment, otherwise it will affect normal operation and even damage the battery.

All of our capacitors are in line with the EU ROHS directives and REACH regulations.
7. How long is the charging time of the super capacitor?
Fast charging is one of supercapacitor’s characteristics. Charging for 10 seconds to 10 minutes, a supercapacitor can reach more than 95% of its rated capacity. Supercapacitors have a very high power density, 10-100 times that of batteries, and are suitable for short-time high-power output; the charging speed is fast and the mode is simple, it can be charged with high current, and the charging process can be completed in tens of seconds to several minutes. It is fast charging in the true sense; there is no need to check whether it is full, and there is no danger of overcharging.
8. How does the leakage current affect the supercapacitor?
When the supercapacitor’s voltage becomes stable, the voltage on each unit of the supercapacitor will change as the leakage current (instead of capacitance) changes. The greater the leakage current, the lower the rated voltage and vice verse. This is because leakage current will cause the supercapacitor unit to discharge and thus reduce its voltage. As a result, the voltage of other units connected in series with it will also be affected (assume that all the supercapacitor units are powered by the same constant voltage).
9. What would influence the leakage current of Supercapacitors?
From the prospective of the production, the leakage current has much to do with the raw materials and manufacturing process. From the actual use environment, three factors may affect the leakage current:
1) Voltage: the higher the voltage, the higher the leakage current;
2) Temperature: the lower the temperature, the lower the leakage current;
3) the smaller the capacitance of the supercapacitor, the smaller the leakage current. Also, the leakage current will become smaller when the supercapacitor is under use.
10. Why is the voltage of Supercapacitors so low?
In order for large capacitance, the dielectrics should be made very thin and thus the voltage will be low.
11. Can a simple energy calculation method be used when selecting a super capacitor for a backup power system?
Simple electric energy calculation methods may not meet the requirements, unless you take into account all the factors that affect the energy storage performance of the entire life cycle of the supercapacitor.
12. When the temperature of the super capacitor is too high, will its capacity decrease?
When the ambient temperature is too high, the compensation ability of the super capacitor will be reduced, and it will also produce harmonic resonance with a certain frequency in the power grid, which will cause certain damage to the system. Therefore, we should consider the impact of temperature increase on the operation of the super capacitor. Otherwise the capacity of the super capacitor will be reduced, resulting in damage to the system.
