 Product introduction In conclusion, the working voltage of single ultracapacitors is generally 1V-4V, and the common voltage specification of single ultracapacitors is generally 2.7V. In practical application, 16V, 48V, 54V, 75V, 125V or higher voltage is usually needed to meet the use of these devices. Most of these devices are wind power generation, automobile HEV, military starting power supply and microgrid equipment, etc. In order to meet the requirements of these devices, the ultracapacitor module came into being. The ultracapacitor module is a new energy package which combines several ultracapacitors in series with voltage equalization and discharge stabilizing system and aluminum alloy shell. The birth of supercapacitor module makes up for the defects of lead-acid battery and other energy storage devices. The working temperature range of supercapacitor module is from -40 ℃ to 65℃, which solves the problem that the efficiency of lead-acid battery is greatly reduced in outdoor cold conditions. Moreover, the ultracapacitor module not only has all the characteristics of the ultracapacitor, but also has the status monitoring function, which can better realize maintenance-free and easy maintenance; The supercapacitor module has the following advantages: 1, super capacitor module is green energy (activated carbon), does not pollute the environment. 2. Long service life of supercapacitor module (charging times: 100,000 times); Lead-acid battery has a short life (charge times 500 times), easy to damage, difficult to manage, is 20-200 times of lead-acid battery can be with the same fate of equipment. 3, the supercapacitor module charging speed is fast (0.3 seconds to 15 minutes); Lead-acid batteries take a long time to charge (5-8 hours), and many batteries simply take a long time to charge and have a short driving range. 4. High charge-discharge efficiency of supercapacitor module (98%); Lead acid battery low charge and discharge efficiency (70%); 5. High power density of supercapacitor module (10.000W/kg); Lead acid battery power density is low (300W/kg), the difference is more than 30 times. 6, supercapacitor module completely maintenance free, operating temperature range (-40~50); The range of lead-acid electric vehicles at -40℃ is reduced by 90%, and that of supercapacitors by only 10%. 7, super capacitor module in the electric bus energy recovery, emergency brake energy recovery up to 75%; The lead-acid battery's energy recovery is only 5%, which is too important for public buses to save a lot of fuel. 8, the relative cost of supercapacitor module is low. Supercapacitors cost twice as much as lead-acid batteries and will fall in price after mass production; But ultracapacitors last up to 10 times longer than lead-acid batteries, which is important for the industrialisation of public buses. 9, supercapacitor module also has the function of automatic alarm over temperature and voltage, which can better protect other equipment and ensure the normal operation of equipment |
