Yuav ua li cas qhib lithium roj teeb
Many people have bad habits. People often put the battery of the electric vehicle on the car when they are not at home, the air switch is not turned off, and they do not ride for a few months. When I came back for a ride a few months later, I found that the car was dead and couldn't charge. The charger is plugged in, but the green light is always on, even if it is plugged in for 24 hours, the green light is still green, because the battery voltage is too low, and if the difference between the output voltage of the charger and the charger is too large, the charger cannot charge electricity into the battery.
This situation is what people usually say that the battery is "starved to death". The voltage of this kind of battery block battery is generally only about 5.6V, which will not exceed 6V. For such batteries, most of them are battery replacements. But it's a pity to replace a set of batteries by hundreds, especially if the battery has just been out of warranty.
Here are five better ways to save most of these "starved" batteries. Note that most are not 100 percent .
1. Concatenation method. Txuas lwm qhov ib txwm muaj hluav taws xob 12-volt roj teeb hauv cov koob nrog tag nrho cov roj teeb pob. Piv txwv li, yog hais tias tus thawj lub tsheb yog 48V-20AH roj teeb, ces peb yuav txuas lwm 12V-20AH roj teeb nyob rau hauv series. Lub roj teeb 12V nrog lub zog txaus muaj qhov hluav taws xob ntawm 13V. Tom qab txuas hauv series, qhov voltage ntawm tag nrho cov roj teeb tuaj yeem nce ntxiv, thiab tom qab ntawd nws tuaj yeem them nrog nws cov thawj charger. Hauv qhov no, lub roj teeb tuaj yeem raug them. Tom qab ntsaws rau hauv lub charger, lub charger Nws yog lub teeb liab, koj tuaj yeem them lub roj teeb rau lub sijhawm no. Thaum lub charger hloov ntsuab, tshem tawm lwm lub roj teeb uas txuas nrog hauv cov koob. Tom qab ntawd koj tuaj yeem them nws ib txwm.
Thib ob, txoj kev sib luag. Txoj kev no yog me ntsis cumbersome. Piv txwv li, lub tsheb yog Ameslikas yog 48V-20AH roj teeb, thiab peb muaj lwm txheej ntawm 48V-20AH roj teeb nyob rau hauv parallel. Peb txhua tus paub tias qhov hluav taws xob nyob txhua qhov chaw hauv ib lub voj voog sib luag yog sib npaug, thiab qhov hluav taws xob hluav taws xob siab yuav ntws mus rau hauv qhov hluav taws xob tsawg. Txoj kev no kuj yog siv los ntawm ntau lub tuam txhab roj teeb los kuaj xyuas cov roj teeb uas tuag tag. Tom qab ntawd kev them nyiaj kuj tuaj yeem ua tiav lub hom phiaj ntawm kev them nyiaj. Lub hauv paus ntsiab lus no zoo ib yam li kev sib txuas ntawm lub roj teeb hauv koob. Nws kuj nce qhov voltage ntawm tag nrho cov pab pawg neeg.
3. Tsawg-voltage charging method. Siv lub charger me me rau kev them nyiaj. Piv txwv li, nws yog ib txheej ntawm 60V-20AH roj teeb, ces peb siv 48V-20AH charger rau them. Feem ntau, nws tuaj yeem raug them. Lub hauv paus ntsiab lus tseem zoo ib yam li thawj zaug, nqa qhov kev them nqi hluav taws xob los ze zog rau qhov hluav taws xob hla lub roj teeb.
Plaub, txoj kev them nyiaj ib zaug xwb. Them ib lub roj teeb nrog 12-volt maus taus charger tuaj yeem qhib lub roj teeb, tab sis qhov kev them nyiaj no kuj qeeb. Feem ntau, nws yuav siv sij hawm ntau tshaj 7 teev rau lub roj teeb voltage maj mam nce mus txog 12V. Nws yuav siv sij hawm los them tag nrho ib qho blocks.
Tsib, tshwj xeeb charger txoj kev. Tianneng charger tau lees paub lub roj teeb voltage, txawm tias muaj pes tsawg volts ib pawg roj teeb muaj, nws tuaj yeem paub qhov voltage, thiab nws tuaj yeem them nws. Piv txwv li, lub tsheb qub muaj 60V-20AH roj teeb, tab sis tam sim no nws tsawg dua 30V, thiab nws tseem tuaj yeem them rau sab hauv. Raws li qhov voltage nce, nws tag nrho yoog mus rau qhov kev txiav txim siab dua, thiab tom qab ntawd them lub roj teeb. Tailing, Lvjia electric tsheb thiab Jinpeng tricycle tau nruab nrog chargers ntawm hom no.
