Ib qho yooj yim tshaj plaws chemistry ntawmLithium roj teebyog hom Lithium Iron Phosphate (LiFePO4).Qhov no yog vim hais tias lawv tau dhau los ua kev lees paub tias muaj kev nyab xeeb tshaj plaws ntawm Lithium ntau yam thiab muaj kev cog lus thiab lub teeb heev thaum piv rau cov roj teeb uas muaj peev xwm sib piv.

Ib qho kev ntshaw niaj hnub no yog los hloov lub roj teeb ua kua qaub nrogLiFePO4nyob rau hauv ib tug system uas twb muaj ib tug built-in charging system.Ib qho piv txwv ntawm ib qho yog lub twj tso kua mis roj teeb thaub qab.Vim tias cov roj teeb rau cov ntawv thov no tuaj yeem tuav ntau qhov ntim hauv qhov chaw kaw, qhov nyiam yog nrhiav lub txhab nyiaj roj teeb ntau dua.

Nov yog yam yuav tsum paub txog:

★12 V lead acid roj teeb muaj 6 lub hlwb.Nyob rau hauv thiaj li yuav kom lawv them kom zoo cov tib neeg lub hlwb yuav tsum tau 2.35 volts kom them tag nrho.Qhov no ua rau tag nrho qhov yuav tsum tau muaj voltage rau lub charger yog 2.35 x 6 = 14.1V

★ 12V LiFePO4 roj teeb tsuas muaj 4 lub hlwb xwb.Txhawm rau kom paub ua tiav kev them nqi nws tus kheej lub hlwb xav tau 3.65V volts kom them tag nrho.Qhov no ua rau lub charger tag nrho voltage yuav tsum tau 3.65 x 4 = 14.6V

Nws tuaj yeem pom tias qhov hluav taws xob siab dua me ntsis yuav tsum tau them tag nrho cov roj teeb lithium.Yog li ntawd, yog hais tias ib tug tsuas yog yuav tsum tau hloov cov lead acid roj teeb nrog lithium, tawm hauv tag nrho lwm yam raws li yog, tsis tiav them yuav tsum tau rau lub Lithium roj teeb - qhov chaw ntawm 70% -80% ntawm tag nrho cov nqi.Rau qee qhov kev siv qhov no yuav tsim nyog, tshwj xeeb tshaj yog yog tias cov roj teeb hloov pauv muaj lub zog ntau dua li cov roj teeb lead acid qub.Lub roj teeb ntim txo yuav muab qhov chaw loj-txuag thiab kev ua haujlwm tsawg dua 80% lub peev xwm siab tshaj plaws yuav txhim kho lub neej ntawm lub roj teeb.
