Double-layer capacitance module

Product introduction:        

        Double-layer capacitor generally refers to double-layer capacitor. Electrical Double-Layer Capacitor is a kind of super capacitor and a new type of energy storage device. The double-layer capacitance is between the battery and the capacitance, and its huge capacity can be used as a battery completely.

Application field:

Super capacitors are widely used in automobile motor starting, solar energy, solar energy storage, cordless phones, mobile phones, digital cameras, smart appliances, electronic toys, smart door locks, smart meters, MP3, PDA, DVD, VTR, GPS, PLC, fax machines, audio equipment, rice cookers, electric water heaters, self powered super flashlights, printers, tail lights, electronic

The double-layer supercapacitor module has the following advantages:

1. Green energy (activated carbon) does not pollute the environment.

2. Long service life (100000 times of charging); The lead-acid battery has a short life (500 times of charging), is easy to be damaged and difficult to manage. It is 20-200 times as long as the lead-acid battery and can share the same fate with the equipment.

3. Fast charging speed (0.3 seconds - 15 minutes); Lead-acid batteries have a long charging time (5-8 hours). Many batteries have a long charging time and a short driving range.

4. High charge-discharge efficiency (98%); The charge and discharge efficiency of lead-acid battery is low (70%);

5. High power density (10.000W/kg); The power density of lead-acid battery is low (300W/kg), more than 30 times worse.

6. Completely maintenance-free, operating temperature range (- 40~50); The driving range of lead-acid battery electric vehicles at - 40 ℃ is reduced by 90%, and the supercapacitor is only reduced by 10%.

7. In the electric bus, the energy recovery is strong, and the emergency braking energy recovery is 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 is low. The price of supercapacitors is twice as high as that of lead-acid batteries, and the price will drop after mass production; However, the service life of supercapacitors is 10 times longer than that of lead-acid batteries, which is very important for the industrialization of public buses.

9. It has the function of over-temperature and over-pressure automatic alarm, which can better protect other equipment and ensure the normal operation of the equipment;

使用事项：

超级电容器不可使用在如下状态：

1) 超过标称温度的温度

当电容器温度超过标称温度时，将会导致电解液分解，同时电容器会发热，容量下降，

而且内阻增加，寿命缩短。

2) 超过额定电压的电压

当电容器电压超过标称电压时，将会导致电解液分解，同时电容器会发热，容量下降，

而且内阻增加，寿命缩短。所以降低使用电压可提高使用寿命。

3) 逆电压或交流电压的加载

1.周围温度对超级电容器的影响

超级电容器的使用寿命受使用温度的影响，一般情况下，使用温度提升10℃，超级电容器的寿命会缩短一半，请尽量在低于最高使用温度的低温环境下使用。超过最高使用温度使用的话，可能会造成特性急剧劣化，破损。

超级电容器的使用温度不仅要确认设备周围温度，内部温度，还要确认设备内发热体（功率晶体管、电阻等）的放射热，纹波电流引起的自行发热温度。此外，还请勿将发热体安装在超级电容器的附近。

2.请按电容器的正负极标识正确使用。

3.请避免在以下环境中使用超级电容器。

a) 直接溅水、盐水及油的环境、或处于结露状态、充满着气体状的油分或盐分的环境。

b) 充满着有害气体（硫化氢、亚硫酸、氯、氨、溴、溴化甲基等）的环境。

c) 溅上酸性及碱性溶剂的环境。

d) 阳光直射或有粉尘的环境。

e) 遭受过度的振动及冲击的环境。

4.在焊接过程中要避免使电容器过热（1.6mm的印刷线路板，焊接时应为260℃，时间不超过5s）。

5.请避免在超级电容器的引出极间或连接板焊点间进行电路配线。

6.过电压及超过工作温度范围等超出额定条件使用时，可能导致压力阀动作，电解液会喷出。因此，请采用已考虑到此异常状况可能发生的设计方法。

7.快速充放电时，充电开始时、放电开始时，会产生由内部阻抗导致的压降(也叫IR降），所以，请采用已考虑到电压变化幅度的设计方法。

8.功率型大容量产品（约10F以上产品）充电状态下如果端子短路，会有数百安培的电流流过，危险。请不要在充电状态下进行安装和拆卸。

9.不要把电容器放入已溶解的焊锡中，只在电容器的导针上粘焊锡。不可让焊接用焊棒接触电容器热缩管。

10.安装后，不可强行扭动或倾斜电容器。

11.超级电容器串联使用时，存在单体间的电压均衡问题。
