1. Supercapacitor are green energy sources (activated carbon) and do not pollute the environment; lead-acid batteries pollute the environment.

2. Advantages of supercapacitors: extremely long life, with a cycle life of 3000 to 5000 times; the cycle times of lead-acid batteries are only 300 to 500 times.

3. The charging speed is extremely fast: an electric bicycle can be fully charged in 2 to 3 minutes; a lead-acid battery takes 5 to 8 hours. Supercapacitors can be deeply discharged and can be charged with high current; lead-acid batteries are not allowed to be deeply discharged and high current charging is not allowed.

4. The price of supercapacitor: a little higher than that of lead-acid batteries (1/3 higher), but the service life is 5 times higher than that of lead-acid batteries. The price of lithium-ion batteries is three times higher than that of super capacitors.

5. The size of the super capacitor: It is customized according to the existing standard electric bicycle battery box size. Generally, the battery box of the electric bicycle and the super capacitor can be put in.

6. ​​None of the electric vehicle companies have installed super capacitors. It can be said that installing super capacitors on electric bicycles is a pioneering work.

7. Compared with lead-acid batteries, super capacitors are completely maintenance-free. Supercapacitors do not require human management and maintenance. Lead-acid batteries need to be managed and taken care of by people. Large capacitors can work at -30°C to -40°C, and lead-acid batteries basically cannot work at this temperature.

8. Supercapacitors can recover up to 75% of electric energy in terms of braking energy and downhill potential energy; lead-acid battery energy recovery is only 5%. This kind of energy recovery of super capacitors can save a lot of electric energy.

9. The charging and discharging efficiency of supercapacitors is as high as 98%, and the charging and discharging efficiency of lead-acid batteries is as low as 70%. The difference between the two is close to 30%. This also means that about 30% of energy can be saved. At the critical moment of energy saving and emission reduction, this is A very important indicator.
