Cov txiaj ntsig thoob thoob: Tus nqi dej hauv lub thoob tuaj yeem tuav tau nyob ntawm nws qhov luv tshaj plaws stave.
Nyob rau hauv lub cheeb tsam ntawm cov roj teeb, lub Buckets Effect tau pom: Qhov kev ua tau zoo ntawm lub pob roj teeb nyob ntawm lub xov tooj ntawm tes nrog qhov hluav taws xob qis tshaj. Thaum qhov ntsuas hluav taws xob tsis zoo, qhov tshwm sim tshwm sim tias lub roj teeb tau them tag nrho tom qab lub sijhawm them luv luv.
Txoj kev cai qub:
Phau ntawv kev tshuaj xyuas ib ntus txhawm rau txheeb xyuas cov roj teeb uas tsis tshua muaj hluav taws xob thiab tus kheej them cov roj teeb uas muaj hluav taws xob tsawg.
Txoj kev ntse:
BMS (Battery Management System) yog nruab nrog qhov tsis siv neeg ntsuas kev ua haujlwm uas tuaj yeem ua qhov sib npaug ntawm qhov hluav taws xob thaum them thiab tawm.
Tsis siv neeg ntsuas qhov ntsuas muaj xws li nquag thiab passive ntsuas.
Active balancing muaj xws li them-raws li thiab lub zog-hloov-raws li ntsuas.
Kev sib npaug yog nqa tawm los ntawm kev tsis muaj kev hloov pauv ntawm lub zog, piv txwv li, lub zog hloov pauv los ntawm cov hlwb uas muaj hluav taws xob ntau dua rau cov uas muaj qhov hluav taws xob qis, ua tiav tag nrho cov hluav taws xob sib npaug nrog tsawg zog poob; li no, nws tseem hu ua lossless balancing.
Qhov zoo: Tsawg zog poob, kev ua haujlwm siab, lub sijhawm ntev, siab tam sim no, cov nyhuv nrawm.
Disadvantages: complex circuitry, tus nqi siab.
Muaj DC / DC fais fab module nyob rau hauv txhua qhov kev soj ntsuam ntawm tes sensor. Thaum lub sij hawm float charging, lub module tsub lub cell nrog rau qhov qis tshaj voltage kom nws cov nqi kom txog rau thaum mus txog rau lub teeb voltage tshuav nyiaj li cas.
Qhov zoo: Lub hom phiaj them rau cov hlwb uas tsis muaj nqi lossis qis dua.
Qhov tsis zoo: Tus nqi siab vim qhov xav tau ntawm DC / DC fais fab modules, kev pheej hmoo ntawm kev them nyiaj ntau dhau (muaj peev xwm txiav txim siab tsis raug), tus nqi tu siab vim muaj peev xwm ua tsis tiav.
Passive ntsuas feem ntau suav nrog kev tso tawm cov hluav taws xob ntau dua los ntawm cov khoom siv hluav taws xob, tso tawm lub zog hauv daim ntawv ntawm cov cua sov kom ua tiav tag nrho cov hluav taws xob sib npaug, yog li tso cai rau lwm lub hlwb ntau lub sijhawm them nyiaj thaum lub sijhawm them nyiaj.
Qhov zoo: Tsis tshua muaj paug tam sim no, txhim khu kev qha technology, nqi-zoo.
Disadvantages: Lub sijhawm luv luv, ua haujlwm qeeb.
Hauv cov ntsiab lus, tam sim no BMS rau cov roj ntsha lead-acid feem ntau siv qhov ntsuas tsis zoo. Nyob rau hauv lub neej yav tom ntej, Dfun yuav qhia hybrid balancing, uas sib npaug high-voltage cells los ntawm kev tso tawm thiab qis-voltage hlwb los ntawm kev them nyiaj.
