Weligaa ma is weydiisay sida aBMSma ogaan kartaa hadda xirmada baytariyada lithium? Ma ku dhex dhisay multimeter?
Marka hore, waxaa jira laba nooc oo ah Nidaamyada Maareynta Battery-ga (BMS): nooca smart iyo hardware. Kaliya BMS-ga caqliga leh ayaa awood u leh gudbinta macluumaadka hadda jira, halka nooca hardware-ka uusan lahayn.
BMS caadi ahaan waxa ay ka kooban tahay kontoroolka isku dhafka ah ee wareegga (IC), MOSFET furayaasha, wareegyada la socodka hadda, iyo wareegyada la socodka heerkulka. Qaybta ugu muhiimsan ee nooca smart waa kantaroolka IC, kaas oo u shaqeeya sida maskaxda nidaamka ilaalinta. Waxay mas'uul ka tahay la socodka wakhtiga dhabta ah ee batteriga. Marka lagu xidho wareegga la socodka hadda, kantaroolka IC waxa uu si sax ah u heli karaa macluumaadka ku saabsan hadda batteriga. Marka hadda uu dhaafo xadka badbaadada ee hore loo dejiyay, kantaroolka IC si dhakhso ah ayuu u sameeyaa xukun wuxuuna kiciyaa tallaabooyinka ilaalinta ee u dhigma.
Haddaba, sidee hadda lagu ogaadaa?
Caadi ahaan, dareemaha saamaynta Hall ayaa loo isticmaalaa si loola socdo hadda. Dareemahani waxa uu isticmaalaa xidhiidhka ka dhexeeya meelaha magnetic iyo hadda. Marka hadda uu dhex socdo, goob birlab ah ayaa ka abuurma agagaarka dareemaha. Dareemuhu wuxuu soo saaraa calaamad danab u dhigma oo ku salaysan xoogga goobta magnetic. Marka kantaroolka IC uu helo calaamaddan danab, waxay xisaabinaysaa cabbirka dhabta ah ee hadda jira iyadoo la adeegsanayo algorithms gudaha ah.
Haddii hadda uu ka bato qiimaha badbaadada ee hore loo dejiyay, sida hadda socda ama wareegga gaaban, kontoroolka IC ayaa si degdeg ah u xakameyn doonta furayaasha MOSFET si ay u gooyaan dariiqa hadda socda, iyagoo ilaalinaya batteriga iyo dhammaan nidaamka wareegga.
Intaa waxaa dheer, BMS waxay isticmaali kartaa qaar ka mid ah iska caabiyeyaasha iyo qaybo kale si ay uga caawiyaan la socodka hadda. Marka la cabbiro hoos u dhaca korantada ee resistor, cabbirka hadda waa la xisaabin karaa.
Nidaamyadan taxanaha ah ee isku dhafan iyo kuwa saxda ah ee wareegga iyo hababka xakamaynta ayaa dhamaantood loogu talagalay in lagu kormeero wakhtiga batteriga iyadoo laga ilaalinayo xaaladaha xad dhaafka ah. Waxay door muhiim ah ka ciyaaraan hubinta isticmaalka badbaadada leh ee baytariyada lithium, fidinta nolosha batteriga, iyo kor u qaadida isku halaynta nidaamka batteriga oo dhan, gaar ahaan codsiyada LiFePO4 iyo nidaamyada kale ee taxanaha BMS.
