Characteristics of super Capacitor:  

  (1) fast charging, charging 10 seconds to 10 minutes can reach the rated capacity of more than 95%;

(2) long cycle life, depth charge discharge cycle use frequency can reach 20000 times, no "memory effect", there is no excessive discharge problem;

(3) the large current discharge ability is strong, the energy conversion efficiency is high, the process of loss, high current energy efficiency higher than 90%;

(4) composition, product raw material production, use,storage and dismantling process has no pollution, is a green environmental protection power ideal;

(5) the charge circuit is simple, no need to charge the battery as the charging circuit, the long-term use ofmaintenance free;

(6) the ultra low temperature characteristics, wide temperature range of -25 ~ +85;

(7) the detection is convenient, the remaining power can be read directly;

(8) the capacity range is usually 0.01F~1000F, andpressure is often low (a few volts to 10 volts, newdeveloped but also more than 20 kV).

(10).Quality standard:ISO 9000;ISO 9001:2000;ISO 9001:2008;ISO 14001:2004;CE;ROHS

The super capacitor can be made into a super capacitor module, suitable for high capacity demand.


(1) the pressure of the super capacitor are not high. In practical use, an overvoltage protection circuit. 

There areoften two to a plurality of super capacitor in series toaccess high voltage environment. 

This procedure is not right. Because of the capacitance of the capacitor leakage,and the quality is not the same, 

In the late charge and discharge times of easy to cause the local unit overchargeand breakdown phenomenon.(2) the super capacitor is after all not a battery, the voltagedecreased with the discharge problem, so the need foroutput circuit complex.

1.  for car audio (12V) power amplifier in parallel at both ends
The main role is to give an instant sound system capacity additions and filtering. Car stereo CD player, MD player, DVD player, amplifier and high-end power amplifiers auxiliary components to improve the quality of audio reproduction.
2. the cold start motorcycle (12V)
In the northern winter when temperatures reach below -10 °C, due to the internal resistance of the battery discharge performance declined significantly increase it, the motorcycle is likely to be difficult to start or repeated start to ignition. Because of good temperature characteristics supercapacitor, can work in an environment -25 °C ~ +85 °C, and has the characteristics of high-current instantaneous release, so you can start using a motorcycle battery and super capacitor in parallel, once the ignition to improve motorcycle cold start performance.
3. the transformation for the electric vehicle (36 ~ 48 ~ 60 ~ 70V)
Most affect the life of lead-acid batteries is starting and high current discharge uphill, make internal plate rapid curing and early retirement.
Capacitor battery is characterized by: charging fast (tens full) allows a large current discharge without damage. Adapt to a wide temperature range without affecting the performance (- 25 °C ~ + 85 °C), charge and discharge cycles more than 20,000 times and performance is almost constant (more than 8 to 10 years)
After the series-parallel capacitor and battery in parallel group, in the start-up and high-current acting uphill, bear most of the large current to the battery discharge tasks, significantly reduce battery current discharge load, or slip into a normal cruise line or downhill, battery to charge the capacitor bank to prepare for the next acting.

After testing, each farad capacitor can be individually driven electric cars run 10 meters -15 meters, a capacitor bank 36V vehicle is three in series, a capacitor bank 48V vehicle is four in series, providing 4.16 Farah capacity can be individually driven electric cars run about 30 meters. Do not underestimate this 30 meters, which spent auxiliary battery electric start and climbing is a great strength. Can extend the battery life more than doubled!
