Product introduction:

Double-layer supercapacitor is a kind of supercapacitor and a new type of energy storage device. The double-layer capacitance is between the battery and the capacitance, and its huge capacity can be used as a battery completely. Compared with the battery based on electrochemical principle, the charge and discharge process of the double-layer capacitor does not involve the change of material at all, so it has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and green environmental protection. The distance between the two electric layers of the double-layer capacitor is very small, which makes the withstand voltage very weak, generally not more than 20V, so it is usually used as the energy storage element in low voltage DC or low frequency situations.

The double-layer supercapacitor module has the following advantages:

1. Green energy (activated carbon) does not pollute the environment.

2. Long service life (100000 times of charging); The lead-acid battery has a short life (500 times of charging), is easy to be damaged and difficult to manage. It is 20-200 times as long as the lead-acid battery and can share the same fate with the equipment.

3. Fast charging speed (0.3 seconds - 15 minutes); Lead-acid batteries have a long charging time (5-8 hours). Many batteries have a long charging time and a short driving range.

4. High charge-discharge efficiency (98%); The charge and discharge efficiency of lead-acid battery is low (70%);

5. High power density (10.000W/kg); The power density of lead-acid battery is low (300W/kg), more than 30 times worse.

6. Completely maintenance-free, operating temperature range (- 40~50); The driving range of lead-acid battery electric vehicles at - 40 ℃ is reduced by 90%, and the supercapacitor is only reduced by 10%.

7. In the electric bus, the energy recovery is strong, and the emergency braking energy recovery is up to 75%; The energy recovery of lead-acid batteries is only 5%, which is too important for public buses and can save a lot of fuel.

8. The relative cost is low. The price of supercapacitors is twice as high as that of lead-acid batteries, and the price will drop after mass production; However, the service life of supercapacitors is 10 times longer than that of lead-acid batteries, which is very important for the industrialization of public buses.

9. It has the function of over-temperature and over-pressure automatic alarm, which can better protect other equipment and ensure the normal operation of the equipment;
