Odipie qhia txog kev daws teeb meem chaw nres tsheb fais fab uas muaj zog heev uas muab kev ruaj khov zoo dua ntawm tus nqi qis dua. Los ntawm kev tsim kho tshiab nrog kev tsim qauv ib lub cell, peb kov yeej cov kev txwv ntawm cov roj teeb ib txwm muaj, xws li kev ua haujlwm poob qis los ntawm kev tsis sib npaug ntawm lub cell. Peb cov thev naus laus zis sib xyaw ua ke ntau yam haujlwm rau hauv ib lub rooj tsavxwm, txo ob qho tib si nyuaj thiab cov nqi khoom siv. Qhov tshwm sim yog lub chaw nres tsheb fais fab 1000Wh txhim khu kev qha thiab tus nqi sib tw, zoo tagnrho rau ntau yam kev siv.
Cov Chaw Fais Fab Nqa Tau Tau Muaj Nyob Hauv Kev Ua Lag Luam Tau Ntau Xyoo Lawm. Lawv sib txuas cov interfaces rau ntau yam khoom siv hluav taws xob, xws li 5.1V USB ports, 12V DC outputs, thiab 110V/220V AC outlets, thaum lawv yooj yim nqa, ua rau lawv nrov ntawm cov neeg nyiam ua si sab nraum zoov. Tsis tas yuav tshawb nrhiav lawv cov xwm txheej siv, tsab xov xwm no qhia txog kev tsim qauv tshiab uas txo cov nqi, txhim kho kev ua haujlwm, thiab txhim kho kev ruaj khov.
Muaj ntau lub chaw fais fab uas siv tau tam sim no hauv khw feem ntau siv cov roj teeb lithium iron phosphate (LFP) 12.8V lossis 25.6V, uas txhais tau tias cov roj teeb no muaj tsawg kawg yog plaub lub cell txuas ua ke. Raws li peb paub, ntau lub cell txuas ua ke, qhov yuav tsum tau muaj lub cell sib xws ntau dua. Thaum siv, yog tias ib lub cell muaj kev puas tsuaj, nws tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub roj teeb. (Raws li kuv qhov kev kwv yees, yog tias ib lub cell ua haujlwm poob qis 5%, tag nrho lub roj teeb ua haujlwm yuav poob qis 5% × 4 = 20%.)
Cov kev daws teeb meem uas twb muaj lawm xav tau cov cell uas sib xws heev, uas ua rau tus nqi kim dua. Yog tias siv cov cell uas tsis sib xws heev, lub neej ntawm lub roj teeb yuav luv dua, ua rau muaj kev siv tsis zoo - qhov no yog qhov tshwm sim uas peb lub hom phiaj yog kom tsis txhob muaj.
Peb txoj kev daws teeb meem tshiab no daws tau cov teeb meem no zoo:
Ib lub cell xwb hloov tau ntau lub cell uas txuas ua ke. Piv txwv li, los tsim ib lub Chaw Fais Fab 1000Wh, peb txoj kev daws teeb meem siv ib lub cell roj teeb 3.2V 314Ah LiFePO4 uas txuas nrog lub 300W bidirectional inverter BMS tiv thaiv board. Txoj hauv kev no tshem tawm qhov xav tau ntawm qhov sib xws ntawm lub cell, zam cov teeb meem tsis sib npaug ntawm qhov hluav taws xob, thiab tshem tawm qhov xav tau ntawm cov txheej txheem sib dhos pob khoom, yog li txo cov nqi. Tsis tas li ntawd, peb lub 300W bidirectional inverter board muaj plaub qhov kev ua haujlwm: kev tiv thaiv roj teeb BMS, lub hnub ci them nqi tswj MPPT, inverter, thiab kev tswj hwm tseem ceeb, txuag tau cov nqi khoom siv ntau heev.
Txawm li cas los xij, qhov kev daws teeb meem no muaj ib qho kev txwv tseem ceeb: vim yog qhov kev txwv ntawm cov hluav taws xob tso tawm ntawm ib lub cell, qhov tso zis hluav taws xob tsis tuaj yeem siab heev. Hauv kev xav, lub zog siab tshaj plaws tuaj yeem ncav cuag 1000W, tab sis qhov no yuav xav tau lub rooj tsavxwm circuit uas muaj peev xwm tswj tau cov hluav taws xob siab, uas yuav ua rau cov nqi nce ntxiv. Xav txog txhua yam, kev teeb tsa ib lub cell rau 1000Wh (1004Wh) 300W Portable Power Station yog qhov kev daws teeb meem zoo tshaj plaws.
