avx鉭電容能夠正確的得到電池的儲能值需要經過多重復雜的核算，電池的容量一般也是不知道的，而且實時地測算也是很困難的。超級電容有更寬的作業溫度范圍，乃至能夠在低至-40℃的溫度下正常作業。而大都電池在溫度低至-10℃時就不能作業。avx鉭電容通過極化高比表面積電極中的電解質作業，電解質、電極和隔離層資料的特性決議了超級電容的電容量功能。高比表面積的電極和小的帶電離子決議了高的電容量；而高效的電解質、隔離層和資料，以及工藝規劃決議了低的阻抗。因為超級電容的能量貯存不依賴化學反應，所以它和電池有著根本上的差異。

在實際(ji)使用中超(chao)級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)84%～95%的(de)轉化功率比大都電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池低于70%的(de)平均(jun)功率高出許多(duo)。超(chao)級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)能(neng)在其許用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓范圍中的(de)任何電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓值(zhi)下充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而(er)(er)且能(neng)夠完全放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。這就允許在總線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓控(kong)制算法中更自在的(de)規劃。而(er)(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池過放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)也是會損壞的(de)。核算超(chao)級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)中的(de)儲能(neng)值(zhi)只需要知道電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)值(zhi)。而(er)(er)超(chao)級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)值(zhi)能(neng)夠通過測(ce)量電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)變化值(zhi)實時的(de)核算出。
