Consolidated above, due to the supercapacitor monomer working voltage is not high, generally only 1V-4V, which commonly used monomer supercapacitor voltage specification is generally 2.7V, and in the actual application of often need 16V, 48V, 54V, 75V, 125V or higher voltage to meet the use of these devices. Most of these devices are wind power generation, automotive HEV, military start-up power and microgrid equipment, etc. In order to meet the requirements of these devices, supercapacitor modules have emerged.
The supercapacitor module is a new type of energy pack that combines multiple supercapacitors in series with a voltage equalization and discharge stabilization system in an aluminum alloy shell. The birth of supercapacitor module makes up for the defects of lead-acid batteries and other energy storage devices, the working temperature range of supercapacitor module is -40~65℃, which solves the problem of lead-acid batteries' efficiency greatly reduced under the outdoor cold conditions; and the supercapacitor module not only has all the characteristics of supercapacitor monomer, but also has the function of state monitoring to better realize the maintenance-free and easy to maintain;
Supercapacitor module has the following advantages:
1, the supercapacitor module is green energy (activated carbon), does not pollute the environment.
2, supercapacitor module long life (charging times 100,000 times); lead-acid battery life is short (charging times 500 times), easy to damage, difficult to manage, is 20-200 times of the lead-acid battery can be the same fate with the equipment.
3, supercapacitor module charging speed (0.3 seconds - 15 minutes); lead-acid battery charging time is long (5-8 hours), many batteries is the charging time is long, short driving range.
4, supercapacitor module charging and discharging efficiency is high (98%); lead-acid battery charging and discharging efficiency is low (70%);
5, supercapacitor module power density is high (10.000W/kg); lead-acid batteries power density is low (300W/kg), the difference is more than 30 times.
6, supercapacitor module completely maintenance-free, operating temperature range (-40 ~ 50); lead-acid battery electric vehicles at -40 ℃ range reduced by 90%, the supercapacitor only 10%.
7, supercapacitor module in the electric bus energy recovery is strong, emergency braking energy recovery of up to 75%; lead-acid battery energy recovery is only 5%, this point is too important for the public **** buses, can save a lot of fuel.
8, the relative cost of supercapacitor module is low. Supercapacitor price is twice as high as lead-acid batteries in mass production, the price will fall; but the life of the supercapacitor than lead-acid batteries 10 times higher, which is very important to the industrialization of public **** buses.
9, supercapacitor module also has over-temperature and over-voltage automatic alarm and other functions, can better protect other equipment, to ensure the normal operation of equipment;
