電表逐步趨于智能化，網(wǎng)絡查看用電信息已經(jīng)取代了傳統(tǒng)的上門收取電費的方式，這就要求數(shù)據(jù)能夠長時間的保存及顯示功能是不可缺少的，現(xiàn)在大部分電表中采用的是各種電池來給時鐘芯片和斷電保護提供電源，通過對超級電容器特性的研究使用超級電容器完全可以實現(xiàn)該功能，并且比使用電池更有優(yōu)勢。
Electricity meters are gradually becoming more intelligent, and online viewing of electricity consumption information has replaced the traditional method of door-to-door collection of electricity bills. This requires that data can be saved and displayed for a long time. Nowadays, most electricity meters use various batteries to provide power to the clock chip and power outage protection. By studying the characteristics of supercapacitors, using supercapacitors can fully achieve this function and has more advantages than using batteries.
超級電容與電池進行比較，有如下一些明顯特性：
Compared with batteries, supercapacitors have the following obvious characteristics:
1、超低串聯(lián)等效電阻（ESR），功率密度(Power Density)是鋰離子電池的數(shù)十倍以上，適合大電流放電。
Ultra low series equivalent resistance (ESR) and power density (Power Density) are tens of times higher than lithium-ion batteries, suitable for high current discharge.
2、超長壽命，充放電大于50萬次，是鋰離子電池的500倍，是鎳氫和鎳鎘電池的1000倍，如果對超級電容每天充放電20次，連續(xù)使用可達68年。
Ultra long lifespan, charging and discharging more than 500000 times, which is 500 times that of lithium-ion batteries and 1000 times that of nickel hydrogen and nickel cadmium batteries. If supercapacitors are charged and discharged 20 times a day, they can be used continuously for up to 68 years.
3、可以大電流充電，充放電時間短，對充電電路要求簡單，無記憶效應，超級電容器充電是雙電層充放電的物理過程或是電極物質(zhì)表面的快速、可逆的化學過程，可采用大電流充電，能在幾十秒到數(shù)分鐘內(nèi)完成充電過程，是真正意義上的快速充電。
Supercapacitor charging can be carried out with high current, short charging and discharging time, simple charging circuit requirements, and no memory effect. Supercapacitor charging is a physical process of double-layer charging and discharging or a fast and reversible chemical process on the surface of electrode material. High current charging can be used, and the charging process can be completed within tens of seconds to minutes, which is truly fast charging.
而蓄電池則需要數(shù)小時完成充電，采用快速充電也需要幾十分鐘。
And the battery takes several hours to complete charging, and using fast charging also takes dozens of minutes.
4、溫度范圍寬-40～+70℃。
The temperature range is wide from -40 to+70 ℃.
5、體積小，外形緊湊，便于安裝，節(jié)省空間，免維護，可密封。
Small in size, compact in shape, easy to install, space saving, maintenance free, and sealable.
6、可以在完全放電狀態(tài)下存儲，而過度放電對許多充電電池都是有害的；
It can be stored in a fully discharged state, while excessive discharge is harmful to many rechargeable batteries;
7、使用安全、方便、綠色環(huán)保對環(huán)境無害。
Safe, convenient, environmentally friendly, and environmentally friendly to use.
正因為智能電表有著以上的優(yōu)勢，未來其應用領(lǐng)域也會更加廣泛，工業(yè)用電、智能建筑用電、智能商業(yè)用電、智能居民用電等各種細分市場上向更專業(yè)、更經(jīng)濟的智能用電產(chǎn)品及系統(tǒng)解決方案的方向發(fā)展。
Because smart meters have the above advantages, their application fields will also be more extensive in the future. Various sub markets such as industrial electricity, smart building electricity, smart commercial electricity, and smart residential electricity will develop towards more professional and economical smart electricity products and system solutions.
