汽車(chē)應(yīng)急啟動(dòng)電源--超級(jí)電容更優(yōu)異
便攜式移動(dòng)電源——汽車(chē)應(yīng)急啟動(dòng)電源能夠在電瓶虧電或者其他原因無(wú)法啟動(dòng)汽車(chē)時(shí)，啟動(dòng)汽車(chē)，成為戶(hù)外出行必備的產(chǎn)品之一。此類(lèi)電源對(duì)放電倍率有較高要求，目前市面可供選擇的有電池和超級(jí)電容兩大類(lèi)。在使用過(guò)程中，電池類(lèi)產(chǎn)品的缺點(diǎn)逐漸暴露：對(duì)運(yùn)行環(huán)境要求苛刻，充電時(shí)間長(zhǎng)，循環(huán)壽命短。與之相比，超級(jí)電容器的特點(diǎn)突出：高效率、大電流放電、寬電壓、寬溫度范圍、長(zhǎng)循環(huán)壽命、免維護(hù)，更適合應(yīng)急啟動(dòng)的工況。
電池類(lèi)產(chǎn)品以鉛酸蓄電池和鋰聚合物類(lèi)電池為主。鉛酸蓄電池類(lèi)汽車(chē)應(yīng)急啟動(dòng)電源的歷史比較久遠(yuǎn)。電流范圍大致在350—1000A，一般會(huì)配備相應(yīng)的充氣泵，支持過(guò)流、過(guò)載、過(guò)充以及反接指示保護(hù)等功能，不過(guò)質(zhì)量和體積都較大。鋰聚合物類(lèi)汽車(chē)應(yīng)急啟動(dòng)電源啟動(dòng)汽車(chē)的電流可達(dá)到300—400 A，一般不配備充氣泵，具有過(guò)充關(guān)斷功能。
近幾年出現(xiàn)的超級(jí)電容類(lèi)汽車(chē)應(yīng)急啟動(dòng)電源較為新穎。Sangueblu超級(jí)電容器產(chǎn)品具有大電流放電特性，其高倍率放電特性足以和電池類(lèi)產(chǎn)品媲美，同時(shí)在寬工作溫度范圍，快速放電和長(zhǎng)使用壽命方面具有絕對(duì)的優(yōu)勢(shì)。
作為汽車(chē)應(yīng)急啟動(dòng)電源的新興選擇，超級(jí)電容的功率密度大、快速充放電等特性充分滿(mǎn)足了車(chē)輛啟動(dòng)的快速響應(yīng)需求，并將在該領(lǐng)域扮演越來(lái)越重要的角色。
Automobile emergency starting power supply: super capacitor is more excellent
Portable mobile power supply - vehicle emergency starting power supply can start the vehicle when the battery is out of power or the vehicle cannot be started for other reasons. It has become one of the necessary products for outdoor travel. This kind of power supply has high requirements for discharge rate. At present, there are two types of batteries and super capacitors on the market. In the process of use, the disadvantages of battery products are gradually exposed: harsh requirements for the operating environment, long charging time and short cycle life. In contrast, supercapacitors have outstanding characteristics: high efficiency, high current discharge, wide voltage, wide temperature range, long cycle life and maintenance free. They are more suitable for emergency start-up.
Battery products are mainly lead-acid batteries and lithium polymer batteries. The emergency starting power supply for lead-acid battery vehicles has a long history. The current range is about 350-1000a. Generally, corresponding inflation pump will be equipped to support overcurrent, overload, overcharge, reverse indication protection and other functions, but the mass and volume are large. The emergency starting power supply for lithium polymer vehicles can start the vehicle with a current of 300-400 A. generally, it is not equipped with an inflation pump and has the function of overcharge shutdown.
The super capacitor automobile emergency starting power supply appeared in recent years is relatively novel. MWM products have high current discharge characteristics, and its high-rate discharge characteristics are comparable to battery products. At the same time, MWM products have absolute advantages in wide working temperature range, rapid discharge, and long service life.
As a new choice of automobile emergency starting power supply, the characteristics of super capacitor, such as high-power density and rapid charge and discharge, fully meet the rapid response needs of vehicle starting, and will play a more and more important role in this field.
