(1)超级电容器极性问题 与普通电解电容器或电池不同的是,由于超级电容器正负极采用的是同种材质,从理论上讲是不存在极性的;而超级电容器所标识的极性是生产商在生产工艺过程制定的,当电容使用中不小心短期反向使用,不会造成电容器实质性破坏,调整为正向可保证使用,但不可长期反向使用,会造成电容寿命特性迅速衰减。

(1)超级电容器极性问题 The polarity of super capacitor


与普通电解电容器或电池不同的是,由于超级电容器正负极采用的是同种材质,从理论上讲是不存在极性的;而超级电容器所标识的极性是生产商在生产工艺过程制定的,当电容使用中不小心短期反向使用,不会造成电容器实质性破坏,调整为正向可保证使用,但不可长期反向使用,会造成电容寿命特性迅速衰减。


Unlike ordinary electrolytic capacitor or battery, the material of positive and negative polarity of super capacitor is same, so theoretically super capacitor has no polarity; the polarities marked on super capacitor are established by

manufacturers in the production process, when the polarities are used reversely in short-term, it won’t cause substantial damage on capacitor, and it can be used normally after adjusting to the right polarities. But if reversely use for a long time, the life of super capacitor will decay quickly.

(2)关于超级电容器充电问题Super capacitor charging information


超级电容器充电需要采用不超过额定电压的直流电压,可采用限流、恒流、恒功率、恒电压等多种充电方式;超级电容器充电时可能会拉低充电电源电压,直到电容器充满维持电压平衡。


To charge a super capacitor requires DC voltage that no more than the rated voltage. It can be charged by a variety of methods such as current limit, constant current, constant power, constant voltage; when charging, the super capacitor may lower the voltage of charging power supply until the capacitor is full to maintain voltage balance.


(3)超级电容器的内阻及容量问题Internal resistance and capacitance of super capacitor


在充放电过程中,超级电容器的内阻引起的IR降,会损失电容器的充放电效率,故电容器内阻大小在一定程度上决定了电容器品质的优劣,而由于超级电容器的内阻要大于普通电容器,在交流电路或高频率充放电过程中,电容会发热,造成寿命迅速衰减,这也是超级电容一般只用于直流电路的原因。

与普通电容器相比,超级电容器具有较大的时间常数τ,所以充放电时间均较长,也正因为如此,不适合连续的大电流频繁工作,会引起发热性能迅速衰减。超级电容器的频率特性表现为高频率下,碳电极微孔中的正负离子响应时间较长,故表现的容量很小。不可采用普通测量电容器设备交流测量容量,而是要采用基于电池测量mAh方法进行测试。


In the process of charging and discharging, super capacitor’s IR drop caused by inner resistance will leads to lose of efficiency of capacitor charging and discharging, so the size of capacitor determines the quality of capacitor to some extent; due to the internal resistance of the super capacitor is higher than normal capacitors, so in the process of charge and discharge by AC circuit or high frequency circuit, super capacitor will become heating, and this cause life decay quickly,

that’s why super capacitor only commonly used in DC circuit.  

Compared with ordinary capacitor, super capacitor has greater time constant τ , so the charge and discharge time is longer; also because of this,it is not suitable for working with continuous large current frequently as it can cause performance decay rapidly. The frequency characteristic of super capacitor is: the response time of positive and negative ions in carbon electrode pore is longer, so the capacity appears very small. It is not allowed to measure super capacitor by using equipment for testing common capacitors and AC measuring methods, it should be measured by methods for measuring battery for mAh.



(4)工作电压、温度和寿命Operating temperature and product


一般情况,BIGCAP®超级电容器在额定电压、低温条件下工作,漏电流更小、备用时间更长、寿命更长。反之在额定电压、较高温度条件下,则漏电流增大、备用时间缩短、寿命变短。当工作温度一定的条件下,BIGCAP®超级电容器在额定电压以下工作,寿命会增长。


Generally,when BIGCAP® supercapacitors work at rated voltage and low temperatures, the leakage current will be  less ,the standby time and life will be longer. On the contrary, under the condition of rated voltage and higher temperature, the leakage current increases, the standby time is shortened, and the life is shortened. When the operating temperature is certain, the life will increase when working at the rated voltage.


(5)运输及储存Transport and storage


产品运输过程应防止产品受潮,储存温度应为-30℃~50℃、相对湿度小于60%,最大湿度不可超过85%,否则会导致电容受潮性能劣化或生锈。


Should prevent products be affected with damp in product transportation, the storage temperature should be -30℃ to 50℃, relative humidity less than 60%, the maximum humidity no more than 85%, otherwise it will cause degradation of capacitor performance or rust.


(6)安装与焊接Installation and welding


超级电容器用于双面电路板上时,要注意连接处不可经过电容器可触及的地方,否则会导致产品短路过压及电容器损坏。安装过程及安装后,不可强行扭动或倾斜电容器,不得用力拉拽引线,应先断针及折弯后焊接。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),焊接后,线路板和电容器要清洗干净。


When super capacitors are used for double-sided circuit boards, must pay attention the joint should not contact the capacitor, otherwise it will lead to short circuit, over-voltage and damage of capacitor. During the process of installation and after installation, do not twist or tilted the capacitor, do not be forcibly pull the wires. Capacitors should be welded after cutting off and bending the leads. In the welding process, pay attention to avoid overheating of the capacitor ( for a 1.6 mm thickness printed circuit board, the welding temperature should be 260℃, time is not more than 5s) , circuit board and the capacitor should be clean after welding.



(7)超级电容器短路判断The judgement of short circuit of Super capacitor


短路电容应不能进行充放电,在电容正负极间施加直流电压,电容电压不升高,可判定短路,用万用表判定时,新电容在为充电时,以欧姆档测量(短路挡)指示为短路状态,是正常现象,不能确定电容即为短路,应观察阻值是否增加,如增加即为非短路。


When short circuit, the capacitor can not be charged and discharged. Adopt a DC voltage between the positive and negative electrode of capacitor, if the voltage does not rise, then we can determine short circuit occurs; when using a multimeter to judge, when charging a new capacitor, it is a normal phenomenon that ohms shift (short circuit shift) display  short circuit state, at this time, we can not make sure whether the capacitor is short circuit or not, we should observe whether the resistance value is increased, an increasing on resistance value means no short circuit occurs.


(8)串联及并联使用问题Use in series and parallel


相同超级电容器串联使用时,总电压=串联个数×单体耐压;总容量=单体容量÷串联个数;总能量=串联个数×单体容量,总内阻=串联个数×单体内阻。

三个及以上串联存在单体间的电压均衡问题,需要考虑采用均衡电路,用于保证长期使用过程中电容不能过电压使用,从而引起电容器寿命衰减及损坏。客户在自行串联使用时,建议同批次产品一起使用,不建议不同批次产品混用。

超级电容器进行并联使用时,可以不同容值的并联,采用相同电压充电,但要注意各个电容之间的电流平衡问题以及相互隔离,避免由于放电后电势差产生的相互反向充电。


When same super capacitors used in series, the total voltage = capacitor number x capacitor voltage; the total capacitance =single capacitor capacitance / capacitor number; total energy = capacitor number x single capacitor’s capacitance; total resistance = capacitor number x single capacitor’s resistance.

There is a voltage balance problem when 3 pcs or above capacitors used in series, so an equalization circuit is required to ensure the capacitor will not over-voltage in long term use process, as over-voltage will cause decay and damage of capacitor. When customers use the product in series by themselves, we recommend that using the same batch of products, and don’t mix up different batches of products.

Super capacitors in different capacitance value can be used in parallel, theses capacitors should be charged by the same voltage, but should pay attention to the current balance problem between the capacitors and mutual isolation, to avoid potential difference happened after discharge.


(9)其它使用上的问题,请向生产厂家咨询或参照BIGCAP®超级电容器使用说明的相关技术资料执行。
