The advantages of supercapacitor modules

A supercapacitor module is a new type of energy package composed of multiple supercapacitor units connected in series, cooperating with voltage balancing and discharge stabilization systems, and combined with an aluminum alloy casing. The birth of supercapacitor modules has made up for the shortcomings of energy storage devices such as lead-acid batteries. The operating temperature range of supercapacitor modules is between -40~65 ℃, which solves the problem of greatly reducing the power of lead-acid batteries in cold outdoor conditions; And the supercapacitor module not only possesses all the characteristics of supercapacitor monomers, but also has a condition monitoring function, which can better achieve maintenance free and easy maintenance.

Supercapacitor module

The supercapacitor module has the following advantages:

1. High capacitance: The capacity of supercapacitors can reach thousands of faradas, which is thousands of times higher than the capacity of tantalum electrolytic capacitors and aluminum electrolytic capacitors of the same volume.

2. The supercapacitor module has a long lifespan (100000 charging cycles); Lead acid batteries have a short lifespan (500 charging cycles), are prone to damage, and are difficult to manage. They are 20-200 times longer than lead-acid batteries and can share the same fate as devices.

3. Short charging time: Supercapacitors use high current for charging, which can quickly charge in seconds to minutes, while batteries require tens of minutes even for fast charging, and often fast charging can also affect battery life.

4. High charging and discharging power of supercapacitor modules (98%); Low charging and discharging power of lead-acid batteries (70%);

5. High power density of supercapacitor modules (10.000W/kg); Lead acid batteries have a low power density (300W/kg), which is more than 30 times lower.

6. The supercapacitor module is completely maintenance free, with a working temperature range of -40~50; Lead acid battery electric vehicles reduce their range by 90% at -40 ℃, while supercapacitors only reduce it by 10%.

7. The supercapacitor module has strong energy recovery in electric buses, with emergency braking energy recovery reaching 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 of supercapacitor modules is low. The price of supercapacitors is twice that of lead-acid batteries, and the price will continue to decrease after many productions; But the lifespan of supercapacitors is 10 times longer than lead-acid batteries, which is very important for the industrialization of public buses.

9. Reliable operation, maintenance free, and environmentally friendly: Supercapacitors have a certain ability to resist overcharging, which will not have a significant impact on their operation in a short period of time, ensuring the reliability of system operation.
