Yog hais tias qhov hluav taws xob poob yog 100 mV thaum them thiab 100 mV thaum tawm thiab yog tias ηAh ntawm 100% yog assumed, lub efficiency, piv txwv li, rau ib tug Ni-Cd cell nrog 1.2 V nominal voltage yog ηWh=ηU=1.1 V/1.3 V=84.6%. Hauv kev sib piv nrog lithium-ion roj teeb nrog 3.6 V nominal voltage, qhov ua tau zoo yog ηWh=ηU=3.5 V/3.7 V=94.6%.
Ampere-teev efficiency yog dab tsi?
Los ntawm International Dictionary of Marine Aids to Navigation. 6-5-145. Qhov piv ntawm ampere-teev tso zis tau muab thaum lub sij hawm tso tawm ntawm ib tug thib ob cell los yog roj teeb rau lub ampere-teev input yuav tsum tau thaum lub sij hawm them nqi, raws li tau teev tseg tej yam kev mob.
Koj suav li cas watt-teev efficiency?
Peb paub tias, watt teev efficiency yog piv ntawm cov khoom ntawm qhov hluav taws xob tawm thiab tawm tam sim no rau cov khoom ntawm kev them nqi hluav taws xob thiab them tam sim no. Yog li, tag nrho watt teev efficiency yog ib txwm tsawg tshaj li ampere teev efficiency.
Qhov txawv ntawm ampere-teev efficiency thiab watt-teev efficiency yog dab tsi?
Ib (Ah) sib npaug ntawm tus nqi (xav tias electrons) txav los ntawm ib qho tam sim no Amp rau ib teev. … Ib Watt-Hour (Wh) yog lub zog ua haujlwm ntawm lub zog ntawm 1 Watt rau 1 teev. Qhov no tuaj yeem yog, piv txwv li, 1 Amp ntawm 1 Volt rau ib teev, lossis 4 Amps ntawm 0.5 Volts rau ib nrab teev, thiab lwm yam.
Dab tsi yog qhov kev ua haujlwm ntawm roj teeb?
Cov no yog cov roj teeb uas siv tau tshaj plaws. Cov roj teeb lead acid qis dua ntawm txog 90%, thiab cov roj teeb nickel yog ze rau 80%. Cov kev ua tau zoo no poob ntawm tus nqi siab. Lithium-ion nyob ze rau 90% ntawm tus nqi 1C, thaum cov kua qaub ua rau qis dua 50% efficiency.
