Ib qho ntawm 8 qhov tseem ceeb ntawm cov roj teeb lithium roj teeb muaj peev xwm (Ah)
Conversion ntawm capacitance thiab hluav taws xob zog
AH yog ib chav tsev siv los ntsuas lub peev xwm ntawm cov khoom siv cia. Nws lub npe tshawb fawb yog "ampere-teev," uas txhais tau hais tias cov cuab yeej cia tuaj yeem ua haujlwm tsis tu ncua rau 1 teev thaum lub zog siv tam sim no yog 1A. WH yog ib daim ntawv ntawm lub zog (hluav taws xob lub zog) sib npaug ntawm lub roj teeb voltage (V) muab los ntawm lub roj teeb AH. Tus nqi WH no muab faib los ntawm 1000, ua rau KWH (degrees).
Kev hloov pauv mis
1WH=V*AH 1 degree=1KWH=1WH/1000
Piv txwv li, yog tias lub roj teeb yog 48V200ah, nws txhais tau tias lub roj teeb tuaj yeem khaws 48V * 200ah=9.6KWh/1000=9.6 degrees ntawm hluav taws xob.
Peev Xwm (Ntau, chav tsev: Ah)
Lub peev xwm roj teeb yog ib qho tseem ceeb ntawm kev ntsuas kev ua tau zoo rau kev ntsuas roj teeb. Nws qhia txog tus nqi hluav taws xob tawm los ntawm lub roj teeb nyob rau hauv qee qhov xwm txheej (tus nqi tawm, qhov kub thiab txias, qhov hluav taws xob txiav tawm, thiab lwm yam) (JS-150D tuaj yeem siv rau kev kuaj tawm), uas yog, lub peev xwm ntawm lub roj teeb.
Chav tsev ntawm lub roj teeb muaj peev xwm feem ntau yog "mAh" (milliampere-teev) lossis "Ah" (ampere-teev). Nws feem ntau yog ntsuas hauv ampere-teev [abbreviated li A·H, 1A·h=1000mAh=3600C (coulomb)]
Roj teeb muaj peev xwm muab faib ua lub peev xwm tiag tiag, theoretical muaj peev xwm thiab ntsuas lub peev xwm raws li qhov sib txawv
1. Lub peev xwm tiag tiag yog hais txog tus nqi hluav taws xob uas lub roj teeb tuaj yeem muab tau raws li qee qhov kev tso tawm (ib theem, qee qhov ceev tam sim no thiab txiav tawm hluav taws xob). Lub peev xwm tiag tiag feem ntau tsis sib npaug ntawm lub peev xwm ntsuas, thiab nws ncaj qha ntsig txog qhov ntsuas kub, av noo, tus nqi thiab qhov tso tawm, thiab lwm yam. Feem ntau, lub peev xwm tiag tiag yog me ntsis me dua qhov muaj peev xwm ntsuas thiab qee zaum txawm tias me dua li qhov ntsuas. muaj peev xwm;
2. Lub peev xwm theoretical yog hais txog cov hluav taws xob uas tau muab los ntawm txhua yam khoom siv uas koom nrog cov tshuaj tiv thaiv roj teeb. Ntawd yog, lub peev xwm nyob rau hauv lub xeev zoo tshaj plaws;
3. Rated peev yog hais txog lub peev xwm ntawm lub cev muaj zog lossis cov khoom siv hluav taws xob uas tau teev tseg rau ntawm daim ntawv teev npe uas tuaj yeem ua haujlwm ntev ntev hauv kev ua haujlwm tsis zoo. Feem ntau, nws yog hais txog lub zog pom tseeb rau cov hloov pauv, lub zog ua haujlwm rau lub cev muaj zog, thiab lub zog pom tseeb lossis lub zog rov ua haujlwm rau cov khoom siv theem-modulating, nrog rau VA, kVA, thiab MVA;
Qhov ntev geometric, txiav tawm qhov hluav taws xob, qhov kub thiab txias, thiab tus nqi tawm ntawm cov phaj nruab nrab hauv daim ntawv thov yuav cuam tshuam rau lub peev xwm roj teeb. Piv txwv li, nyob rau lub caij ntuj no nyob rau sab qaum teb, yog tias koj siv lub xov tooj txawb sab nraum zoov, lub peev xwm roj teeb yuav poob sai.
Lub zog hluav taws xob (unit: KW·h)
Lub zog hluav taws xob yog ib hom ntawm lub zog. Lub zog hluav taws xob yog lub cev kom muaj nuj nqis uas qhia tias ua haujlwm li cas tam sim no. Lub zog hluav taws xob yog hais txog lub peev xwm ntawm hluav taws xob ua haujlwm hauv ntau hom (yog li qee zaum hu ua hluav taws xob ua haujlwm).
Kev suav lub zog hluav taws xob: W=P (lub zog) ·t (lub sijhawm)=UI·t (kilowatt-teev KW·h)
Lub zog hluav taws xob: Chav tsev hluav taws xob hluav taws xob (chaw hluav taws xob) yog "degree." Nws lub npe scientific yog kilowatt-teev, thiab nws lub cim yog kW·h. Ib kilowatt-teev (1kW·h)=ib kilowatt-teev=1000 watts (W) * 1 teev (h). Nws tuaj yeem nkag siab tias cov hluav taws xob siv los ntawm lub roj teeb uas muaj lub zog ntawm ib kilowatt hauv ib teev.
