Feem ntau, 3.7vlithium roj teebxav tau ib tug "cov ntaub ntawv tiv thaiv" rau overcharge thiab overdischarge.Yog tias lub roj teeb tsis muaj lub rooj tiv thaiv kev tiv thaiv, nws tsuas tuaj yeem siv qhov hluav taws xob them ntawm 4.2v, vim tias qhov zoo tshaj plaws them tag nrho ntawm lub roj teeb lithium yog 4.2v, thiab qhov hluav taws xob ntau tshaj 4.2v.Kev puas tsuaj rau lub roj teeb, thaum them nyiaj hauv txoj kev no, nws yog ib qho tsim nyog los saib xyuas cov xwm txheej ntawm lub roj teeb txhua lub sijhawm.
Yog tias muaj lub rooj tsav xwm tiv thaiv, koj tuaj yeem siv 5v (4.8 txog 5.2 tuaj yeem siv), USB5v ntawm lub khoos phis tawj lossis 5v charger ntawm lub xov tooj ntawm tes tuaj yeem siv.
Rau 3.7V roj teeb, tus nqi txiav tawm hluav taws xob yog 4.2V, thiab qhov hluav taws xob txiav tawm yog 3.0V.Yog li ntawd, thaum qhib Circuit Court voltage ntawm lub roj teeb qis dua 3.6V, nws yuav tsum tau them.Nws yog qhov zoo tshaj plaws los siv 4.2V qhov tsis tu ncua voltage them hom, yog li koj tsis tas yuav them sai sai rau lub sijhawm them nyiaj.Them nrog 5V yog ib qho yooj yim rau overcharge thiab ua rau muaj kev phom sij.

1. Float nqi.Hais txog kev them nyiaj thaum ua haujlwm online.Txoj kev no feem ntau siv nyob rau hauv lub sijhawm thaub qab fais fab mov.Yog tias nws qis dua 12 volts, nws tsis tuaj yeem them, thiab yog tias nws siab dhau, nws yuav cuam tshuam rau kev ua haujlwm ntawm lub voj voog.Yog li ntawd, thaum lub floating nqi ua haujlwm, qhov voltage yog 13.8 volts.

2. Lub voj voog them nyiaj.Hais txog kev them tag nrho lub roj teeb kom rov qab muaj peev xwm.Thaum them tag nrho, lub charger tsis raug txiav rau kev ntsuas.Feem ntau, nws yog nyob ib ncig ntawm 14.5 volts, thiab qhov siab tshaj plaws tsis tshaj 14.9 volts.Tom qab disconnect tus charger rau 24 teev, nws yog feem ntau nyob ib ncig ntawm 13 volts rau 13.5 volts.Txog 12.8 txog 12.9 volts tom qab ib lub lim tiam.Qhov tshwj xeeb voltage tus nqi ntawm cov roj teeb sib txawv yog txawv.

Lub lithium roj teeb li niaj zaus yog 3.7v, qhov voltage yog 4.2v thaum them tag nrho, lub nominal voltage tom qab series kev twb kev txuas tsuas yog 7.4v, 11.1v, 14.8v ... qhov coj tag nrho voltage (uas yog, tsis muaj-load output voltage ntawm lub charger) yog 8.4v, 12.6v, 16.8v ... tsis tuaj yeem yog 12v integers, ib yam li lub sijhawm ntawm cov hmoov lead-acid cia roj teeb yog 2v, tag nrho yog 2.4v, sib npaug tsuas yog cov nominal 6v, 12v, 24v ... tag nrho voltage (Cov. tib yam yog qhov tso zis hluav taws xob ntawm lub charger) raws li 7.2v, 14.4v, 28.8v… Kuv tsis paub tias koj yog lithium roj teeb li cas?
Cov zis ntawm lub charger feem ntau yog 5V, thiab 4.9 volts kuj tsis yog tus qauv.Yog tias koj xav siv lub charger no los them lub roj teeb ncaj qha, nws yuav tsis ua haujlwm, tab sis ntev npaum li nws tau them los ntawm lub xov tooj ntawm tes lossis lub chaw nres nkoj, nws muaj qhov ntsuas hluav taws xob sab hauv.Nws yuav raug txwv tsis pub dhau qhov tso cai ntawm lithium roj teeb, tshwj tsis yog lub Circuit Court puas lawm, tsis txhob txhawj txog qhov no
Lub lithium roj teeb li niaj zaus yog 3.7v, qhov voltage yog 4.2v thaum them tag nrho, lub nominal voltage tom qab series kev twb kev txuas tsuas yog 7.4v, 11.1v, 14.8v ... qhov coj tag nrho voltage (uas yog, tsis muaj-load output voltage ntawm lub charger) yog 8.4v, 12.6v, 16.8v ... tsis tuaj yeem yog 12v integers, ib yam li lub sijhawm ntawm cov hmoov lead-acid cia roj teeb yog 2v, tag nrho yog 2.4v, sib npaug tsuas yog cov nominal 6v, 12v, 24v ... tag nrho voltage (Cov. tib yam yog qhov tso zis hluav taws xob ntawm lub charger) raws li 7.2v, 14.4v, 28.8v… Kuv tsis paub tias koj yog lithium roj teeb li cas?
