Release time:2021-11-29 16:19    views:101

Supercapacitor module is a new type of energy package composed of multiple supercapacitors in series, voltage equalization and discharge voltage stabilization system, and aluminum alloy shell. The birth of super capacitor module makes up for the defects of energy storage devices such as lead-acid battery. The working temperature range of super capacitor module is - 40 ~ 65 ℃, which solves the problem of greatly reducing the service efficiency of lead-acid battery under outdoor cold conditions; Moreover, the super capacitor module not only has all the characteristics of the super capacitor monomer, but also has the condition monitoring function, which can better realize maintenance free and easy maintenance.


Supercapacitor module

The supercapacitor module has the following advantages:

1. High capacitance: the maximum capacity of super capacitor can reach thousand farads, which is thousands of times higher than that of tantalum electrolytic capacitor and aluminum electrolytic capacitor with the same volume.

2. Long service life of super capacitor module (100000 times of charging); Lead acid battery has short service life (500 times of charging), easy to damage and difficult to manage. It is 20-200 times that of lead-acid battery and can share the same fate with the equipment.

3. Short charging time: the super capacitor is charged with high current, which can be quickly charged in a few seconds to a few minutes. Even if the battery is charged quickly, it will take dozens of minutes, and frequent fast charging will affect the battery life.

4. Super capacitor module has high charge and discharge efficiency (98%); The charging and discharging efficiency of lead-acid battery is low (70%);

5. Super capacitor module has high power density (10.000w/kg); The power density of lead-acid battery is low (300W / kg), which is more than 30 times worse.

6. Super capacitor module is completely maintenance free, and the working temperature range is (- 40 ~ 50); The driving range of lead-acid battery electric vehicle at - 40 ℃ is reduced by 90%, and the supercapacitor is only reduced by 10%.

7. Super capacitor module has strong energy recovery in electric bus, and the energy recovery of emergency braking is as high as 75%; The energy recovery of lead-acid battery is only 5%, which is too important for public buses and can save a lot of fuel.

8. The relative cost of supercapacitor module is low. The price of super capacitor is twice as high as that of lead-acid battery, and the price will decline after mass production; However, the service life of super capacitor is 10 times higher than that of lead-acid battery, which is very important for the industrialization of public buses.

9. Reliable operation, maintenance free and environment-friendly: the super capacitor has a certain anti overcharge ability, which will not have a great impact on its work in a short time, which can ensure the reliability of system operation.
