6 Cov Kev Tiv Thaiv Tseem Ceeb los nrhiav Thaum Yuav Cov Roj Teeb Hluav Taws Xob hauv 2023

1. Kev tiv thaiv overcharge

Kev tiv thaiv overcharge yog hais txog: cov roj teeb lithium hauv cov txheej txheem ntawm kev them nyiaj, nrog rau qhov hluav taws xob nce mus rau ntau tshaj qhov tsim nyog, yuav ua rau tsis paub meej thiab txaus ntshai.Kev tiv thaiv overcharge muaj nuj nqi ntawm kev tiv thaiv pawg thawj coj saib xyuas qhov voltage ntawm lub roj teeb pob hauv lub sijhawm tiag tiag, thiab txiav tawm lub zog hluav taws xob thaum lub sijhawm them nyiaj nce mus txog qhov kawg ntawm qhov kev nyab xeeb voltage ntau, tiv thaiv qhov hluav taws xob txuas ntxiv mus, yog li ua si. tiv thaiv lub luag haujlwm.
Overcharge tiv thaiv muaj nuj nqi: Thaum them nyiaj, lub rooj tsav xwm kev tiv thaiv yuav saib xyuas qhov voltage ntawm txhua txoj hlua ntawm lub roj teeb pob hauv lub sijhawm, tsuav yog ib qho ntawm cov hlua hluav taws xob mus txog tus nqi tiv thaiv overcharge (lub neej ntawd overcharge voltage ntawm ternary yog 4.25V ± 0.05 V, thiab lub neej ntawd overcharge voltage ntawm LiFePO4.75V ± 0.05V), lub rooj tsavxwm yuav txiav tawm lub hwj chim mov, thiab tag nrho cov pab pawg neeg ntawm lithium roj teeb yuav tsum tsis them.

2.Kev tiv thaiv tshaj tawm

Kev tiv thaiv tshaj tawm yog hais txog: cov roj teeb lithium hauv cov txheej txheem tso tawm, nrog kev poob qis, yog tias tag nrho cov hluav taws xob tawm mus rau kev qaug zog, cov khoom siv tshuaj lom neeg hauv lub lithium roj teeb yuav poob haujlwm, ua rau kev them nyiaj rau lub zog lossis lub peev xwm poob.Kev tiv thaiv tshaj tawm ntawm lub rooj tiv thaiv kev tiv thaiv yog saib xyuas qhov voltage ntawm lub roj teeb pob hauv lub sijhawm, thiab txiav tawm lub hwj chim thaum tawm mus rau qhov qis tshaj plaws.ntawm lub roj teeb hluav taws xob, tiv thaiv qhov hluav taws xob tsis tu ncua kom poob, thiaj li ua si lub luag haujlwm tiv thaiv.

Kev tiv thaiv tshaj tawm muaj nuj nqi: Thaum tso tawm, lub rooj tsav xwm kev tiv thaiv yuav saib xyuas qhov voltage ntawm txhua txoj hlua ntawm lub roj teeb pob hauv lub sijhawm, tsuav yog ib qho ntawm cov hlua hluav taws xob mus txog qhov kev tiv thaiv tshaj tawm tus nqi (lub neej ntawd over-discharge voltage ntawm ternary yog 2.7V ± 0.1V, thiab lub neej ntawd over-discharge voltage ntawm LiFePO4 yog 2.2V ± 0.1V), lub rooj tsavxwm yuav txiav tawm lub hwj chim mov, thiab tag nrho cov pab pawg neeg ntawm lithium roj teeb yuav tsum tsis txhob tso tawm.

3. Kev tiv thaiv overcurrent

Kev tiv thaiv overcurrent hais txog: cov roj teeb lithium hauv cov khoom siv hluav taws xob rau kev thauj khoom, qhov tam sim no yuav hloov nrog lub zog hluav taws xob thiab lub zog hloov pauv, thaum tam sim no siab heev, nws yooj yim rau hlawv lub rooj tiv thaiv, roj teeb lossis khoom siv.Kev tiv thaiv overcurrent muaj nuj nqi ntawm lub rooj tiv thaiv kev tiv thaiv yog saib xyuas tam sim no ntawm lub roj teeb pob hauv lub sijhawm tiag tiag thaum lub sijhawm them nyiaj thiab tawm, thiab thaum lub sijhawm tam sim no tshaj qhov kev nyab xeeb, nws yuav txiav tawm tam sim no dhau los, tiv thaiv qhov tam sim no.m ua kom puas lub roj teeb lossis khoom siv, kom ua lub luag haujlwm tiv thaiv.

Kev tiv thaiv overcurrent muaj nuj nqi: thaum them thiab tso tawm, pawg tiv thaiv yuav saib xyuas lub roj teeb pob tam sim no nyob rau lub sijhawm tiag tiag, tsuav yog nws ncav cuag tus nqi tiv thaiv overcurrent, pawg tiv thaiv yuav txiav tawm lub zog, thiab tag nrho cov roj teeb lithium. yuav nres them thiab tso tawm.

4.high / qis kub tiv thaiv

Kev tiv thaiv kev kub ntxhov: Kev ntsuas kub ntawm cov khoom siv tiv thaiv lub rooj tsavxwm yog welded rau hauv lub motherboard ntawm lub rooj tiv thaiv kev tiv thaiv thiab tsis tuaj yeem tshem tawm.Lub ntsuas kub tswj kev sojntsuam tuaj yeem saib xyuas qhov ntsuas kub ntawm lub roj teeb pob lossis qhov chaw ua haujlwm hauv lub sijhawm tiag tiag, thaum lub ntsuas kub ntsuas tau tshaj li tus nqi teev tseg (lub neej ntawd ntawm cov khoom siv ntsuas kub tiv thaiv: them -20 ~ 55 ℃, tso tawm -40 ~ 75 ℃, uas tuaj yeem hloov tau raws li tus neeg siv khoom xav tau, thiab cov neeg siv khoom tsis tuaj yeem teeb tsa los ntawm nws tus kheej), lub roj teeb pob yuav raug txiav tawm ntawm kev them nyiaj thiab tawm, thiab lub pob roj teeb tuaj yeem txuas ntxiv mus rau kev them nqi thiab tawm thaum qhov kub thiab txias. rov qab mus rau qhov tsim nyog ntau yam los ua lub luag haujlwm hauv kev tiv thaiv.

5.Equalization tiv thaiv
Passive sib npaug txhais tau tias: thaum muaj qhov tsis sib xws ntawm cov hlua ntawm cov roj teeb, lub rooj tsav xwm tiv thaiv yuav kho qhov voltage ntawm txhua txoj hlua kom zoo ib yam thaum lub sij hawm them nyiaj process.

Equalization muaj nuj nqi: Thaum lub rooj tsav xwm tiv thaiv pom qhov sib txawv ntawm qhov sib txawv ntawm cov lithium roj teeb series thiab cov hlua, thaum them nyiaj, cov hlua hluav taws xob siab ncav cuag tus nqi sib npaug (ternary: 4.13V, LiFe3.525V), tso tawm (siv) nrog qhov sib npaug ntawm cov resistor nrog tam sim no txog 30-35mA, thiab lwm cov hlua hluav taws xob qis txuas ntxiv mus.Txuas ntxiv mus kom txog thaum puv.

6. Kev tiv thaiv luv luv (kev tshawb nrhiav qhov txhaum + kev tiv thaiv kev tiv thaiv rov qab)
Short circuit txhais tau hais tias: luv Circuit Court yog tsim thaum qhov zoo thiab tsis zoo terminals ntawm lub roj teeb txuas nrog directly yam tsis muaj load.Kev luv luv yuav ua rau muaj kev puas tsuaj rau lub roj teeb, khoom siv thiab lwm yam.

Short-circuit tiv thaiv muaj nuj nqi: lithium roj teeb inadvertently tshwm sim los ntawm ib tug luv luv-circuit (xws li txuas lub tsis ncaj ncees lawm kab, coj txoj kab tsis ncaj ncees lawm, dej thiab lwm yam yog vim li cas), lub board tiv thaiv yuav nyob rau hauv ib tug luv luv lub sij hawm ntawm lub sij hawm (0.00025 vib nas this) , txiav tawm ntawm txoj kev tam sim no, thiaj li ua si lub luag haujlwm tiv thaiv.
