The supercapacitor module has the following advantages:
1, super capacitor module charging speed (0.3 seconds - 15 minutes); lead-acid battery charging time (5-8 hours), many batteries are long charging time, driving range is short.
2, super capacitor module long life (100,000 times of charging); lead acid battery life is short (500 times of charging times), easy to damage, difficult to manage, is 20-200 times the lead-acid battery can be the same fate with the equipment.
3, super capacitor module in electric bus energy recovery, emergency braking energy recovery up to 75%; lead-acid battery energy recovery is only 5%, this is too important for public buses, can save a lot of fuel.
4. The charging and discharging efficiency of the super capacitor module is high (98%); the lead-acid battery has low charging and discharging efficiency (70%);
5, super capacitor module power density (10.000W / kg); lead-acid battery power density is low (300W / kg), the difference is more than 30 times.
6, super capacitor module is completely maintenance-free, the operating temperature range (-40 ~ 50); lead-acid battery electric car at -40 ° C driving mileage reduced by 90%, super capacitors only reduced by 10%.
7, super capacitor module is green energy (activated carbon), does not pollute the environment.
8. The relative cost of the super capacitor module is low. The price of supercapacitors is twice as high as that of lead-acid batteries, and the price will drop after mass production; but the life of supercapacitors is 10 times higher than that of lead-acid batteries, which is very important for the industrialization of public buses.
9. The super capacitor module also has the functions of over-temperature and over-voltage automatic alarm, which can better protect other equipment and ensure the normal operation of the equipment;
At the same time, supercapacitor is a new type of green energy-saving energy storage device (activated carbon), which has high efficiency, high current capacity, wide voltage range, wide temperature range, long rewinding service life, long working life and maintenance-free operation. Excellent characteristics such as maintenance, simple integration, and low cost; comprehensively speaking, the super capacitor has a broad development prospect.
