EMU2000-Smart Lithium Battery Management System

Waxaa lagu heli karaa 3 hab wax soo saar

(1) Habka toosan: Beddelka DC ee baytariyada lithium ee caqliga leh waxay qabataa habka tooska ah ee dallacaadda iyo ku shubista, iyo danab moduleka batteriga wuxuu la mid yahay korantada busbarka. (Fiiro gaar ah: Qaabka shaqada ee caadiga ah).

(2) Habka Kobcinta: Batteriga lithium-ka smart wuxuu taageeraa qulqulka tamarta joogtada ah. Marka ay jirto isgaarsiin udhaxeysa batteriga iyo korontada, xadka korantada dekeddu waa 48 ~ 57V (waa la dejin karaa); marka aysan jirin isgaarsiin udhaxeysa batteriga iyo nidaamka sahayda korantada, tirada korantada dekeddu waa 51 ~ 54V (waa la dejin karaa), awooduna kama yara 4800W.

(3) Habka isku dhafka iyo ciyaarta: Smart lithium wuxuu galaa xaalad koronto joogto ah iyadoo loo eegayo isbeddelka korantada ee baska nidaamka korantada, kaas oo xaqiijin kara dheecaanka mudnaanta leh ee isticmaalka aasaasiga ah ee lithium smart. Marka korontada dhexe la gooyo, batteriga lithium ee smart waa la sii dayn doonaa sida doorbidan. Qoto dheer ee batteriga lithium ee caqliga leh waa la dejin karaa (DOD-ga caadiga ah waa 90%). dareeraha, marka baytariyada lithium kale (lead-ashitada) lagu sii daayo si joogto ah hoose ee danab hoose ee batari lithium smart, baytari lithium smart mar kale la sii dayn doonaa ilaa lithium smart ilaalinta hoose-voltage ah, lithium smart waa la sii dayn, kale baytariyada lithium kale (lead-acid) Sii sii daayo.

Ogaanshaha tamarta gacanta iyo batteriga:

Xaqiijinta korantada unuggu waa ± 10mV at 0-45°C, iyo ± 30mV at -20-70°C ee dallaca batteriga iyo soo saarista ogaanshaha hadda. Qiimaha dejinta ee alaarmiga iyo xuduudaha ilaalinta waxaa lagu beddeli karaa iyada oo loo marayo kombuyuutarka martida loo yahay, iyo resistor-ga hadda jira ee ku xiran wareegga ugu weyn ee kharashka iyo dheecaanka waxaa loo isticmaali karaa in lagu ururiyo oo la socdo kharashka iyo sii daynta hadda ee batteriga wakhtiga dhabta ah, si loo ogaado qaylo-dhaanta iyo ilaalinta kharashka hadda iyo dareeraha hadda jira, oo leh saxnaansho heer sare ah oo hadda ah ± 1.

Shaqada ilaalinta wareegga gaaban:

Waxay leedahay shaqada ogaanshaha iyo ilaalinta ee wareegga gaaban ee wax soo saarka.

Awoodda batteriga iyo waqtiyada meertada: Xisaabinta-waqtiga-dhabta ah ee awoodda batteriga ee hadhsan, barashada dhammaystiran ee wadarta lacag-bixinta iyo awoodda saarista hal mar, saxnaanta qiyaasta SOC oo ka wanaagsan ± 5%. Qiyaasta cabbirka awoodda meertada wareegga batteriga waxaa lagu beddeli karaa kumbuyuutarka sare.

CAN, RM485, RS485 isgaarsiineed:

Isgaarsiinta CAN waxay ku xiriirtaa si waafaqsan hab-maamuuska beddelka ee kasta waxaana lagu xiri karaa isgaarsiinta beddelka. La jaanqaadi kara in ka badan 40 nooc.

Ku dallacaadda shaqada xaddidaysa hadda:

Xadidaada hadda firfircoon iyo hababka xaddidaya hadda dadban, waxaad dooran kartaa mid hadba baahidaada tahay.

(1) Xaddidaadda hadda jirta: Marka BMS ay dallacayso, BMS had iyo jeer waxay shiddaa moduleka xaddidan ee MOS tuubada waxayna si firfircoon u xaddidaysaa dallacaadda hadda 10A.

(2) Xaddidaynta hadda jirta: Xaaladda dallacaadda, haddii dallacadu hadda gaadho ku dallacaadda qaylo-dhaanta hadda jirta, BMS waxay daari doontaa 10A xaddidaadda hadda jirta, oo dib-u-hubi haddii dallayuhu uu hadda gaaro xaaladda xaddidan ee hadda jirta kaddib 5 daqiiqo ee xaddididda hadda. (Qiimaha xadka hadda furan ee furan waa la dejin karaa).
