Kev tiv thaiv lithium roj teeb lub rooj tsavxwm feem ntau ua rau lithium roj teeb li cas?
1. Kev tiv thaiv overcharge
Overcharge ntawm lithium roj teeb yog ib qho ua rau tawg. Cov roj teeb lithium yuav tsum ua haujlwm nyob rau hauv qhov ntsuas voltage, txwv tsis pub yuav muaj kev nyab xeeb ntawm kev tawg thiab hluav taws.
Piv txwv li, cov pa roj teeb ternary lithium yog 4.2V-4.35V, uas belongs rau lub overcharge tiv thaiv voltage; cov pa roj teeb lithium hlau phosphate yog 3.65V, uas belongs rau lub overcharge tiv thaiv voltage.
Thaum lub roj teeb lithium raug them, cov lithium ions ntawm qhov zoo electrode txav mus rau qhov tsis zoo electrode thiab yog embedded nyob rau hauv lub network qauv ntawm cov khoom tsis zoo electrode. Yog tias lub roj teeb lithium ion overcharged, nws yooj yim ua rau lithium hauv qhov tsis zoo electrode, ua rau lithium crystallization thiab tho lub diaphragm, uas yuav ua rau hluav taws xob. Lub hauv paus yog luv luv, ua rau tawg.
Yog li ntawd, thaum them lub roj teeb lithium, ib qho kev tiv thaiv overcharge yuav tsum tau ntxiv los tiv thaiv lub lithium roj teeb los ntawm overcharge. Lub lithium roj teeb tiv thaiv board saib xyuas qhov voltage ntawm txhua txoj hlua ntawm lithium roj teeb pob. Yog hais tias lub overcharge voltage ntau dhau, lub lithium roj teeb tiv thaiv board yuav txiav tawm tus nqi los tiv thaiv lithium roj teeb.
2. Kev tiv thaiv tshaj tawm
Overdischarge txhais tau tias overdischarge. Thaum lub roj teeb lithium raug tso tawm, lub zog hluav taws xob khaws cia maj mam tso tawm, thiab qhov hluav taws xob poob qis. Thaum qhov hluav taws xob poob mus rau tus nqi teev tseg, tso tseg thiab rov them rov qab los kho lub roj teeb' lub zog cia lub xeev. Txuas ntxiv tso tawm hauv qab no tus nqi teev tseg, uas yog, tshaj tawm, tshaj tawm tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob, tsis muaj peev xwm tiv thaiv, thiab ua rau lub neej luv ntawm lithium roj teeb.
Piv txwv li, cov pa roj teeb ternary lithium yog 2.5V-2.75V, uas belongs rau cov hluav taws xob tiv thaiv tshaj tawm; cov pa roj teeb lithium hlau phosphate yog 2.0V, uas belongs rau lub over-discharge tiv thaiv voltage.
Yog li ntawd, lub lithium roj teeb yuav tsum tau nruab nrog ib tug over-discharge tiv thaiv Circuit Court los tiv thaiv lub lithium roj teeb los ntawm paug. Lub lithium roj teeb tiv thaiv board saib xyuas qhov voltage ntawm txhua txoj hlua ntawm lithium roj teeb pob. Yog tias qhov hluav taws xob ntau dhau lawm, lub lithium roj teeb tiv thaiv lub rooj tsavxwm yuav txiav tawm cov paug tawm los tiv thaiv lub roj teeb lithium.
3. Kev tiv thaiv tam sim no
Kev tiv thaiv overcurrent yog ib txoj hauv kev tiv thaiv uas ua rau cov cuab yeej tiv thaiv ua haujlwm thaum lub sijhawm tam sim no tshaj tus nqi siab tshaj plaws uas tau teev tseg. Thaum qhov tam sim no ntws los ntawm qhov kev tiv thaiv qub tshaj li tus nqi tau teev tseg, cov cuab yeej tiv thaiv tau qhib, thiab lub sijhawm txwv yog siv los xyuas kom meej qhov kev xaiv ntawm qhov kev txiav txim, kom lub Circuit Court breaker yuav mus los yog muab lub tswb ceeb toom.
Yog li ntawd, thaum tam sim no nyob rau hauv lub lithium roj teeb Circuit Court tshaj tus nqi tsim, rau kev tiv thaiv ntawm lithium roj teeb thiab cov khoom siv hluav taws xob, lub lithium roj teeb tiv thaiv Circuit Court activates lub overcurrent tiv thaiv thiab txiav tawm sab hauv Circuit Court ntawm lithium roj teeb rau kev tiv thaiv.
4. Kev tiv thaiv luv luv
Kev tiv thaiv luv luv-circuit faults tshwm sim los ntawm hluav taws xob luv luv-circuiting ntawm tsis sib npaug-muaj peev xwm conductors nyob rau hauv lub hwj chim mov system. Thaum lub sab nraud zoo thiab tsis zoo ntawm lub lithium roj teeb yog inadvertently luv luv-circuited, rau kev tiv thaiv ntawm lithium roj teeb, lub lithium roj teeb tiv thaiv board pib luv-circuit tiv thaiv thiab txiav tawm sab hauv Circuit Court ntawm lithium roj teeb rau kev tiv thaiv.
5. Kev tiv thaiv kub
Ib hom kev tiv thaiv raws li qhov kub thiab txias hloov ntawm cov roj teeb lithium tiv thaiv raws li lub hauv paus rau kev txiav txim.
Thaum lub roj teeb lithium yog overcharged los yog overcurrent, qhov kub ntawm lub lithium roj teeb yuav xub nce sharply. Thaum qhov kub nce mus rau qhov ntsuas kub tiv thaiv tus nqi tsim los ntawm pawg tswj hwm kev tiv thaiv, kev tiv thaiv qhov kub thiab txias tau qhib thiab cov hluav taws xob sab hauv ntawm lithium roj teeb raug txiav tawm rau kev tiv thaiv.
Cov saum toj no yog ob peb qhov kev tiv thaiv rau Benwei roj teeb los npaj cov roj teeb lithium.
