Litaba - Relay vs MOS BMS Papiso: Tataiso ea Likopo e Phahameng ea Hona Joale

Ha u khethaa Battery Management System (BMS) bakeng sa lits'ebetso tsa morao-raojoalo ka li-forklift tsa motlakase le likoloi tsa bohahlauli, tumelo e tloaelehileng ke hore li-relay li bohlokoa bakeng sa maqhubu a ka holimo ho 200A ka lebaka la mamello ea bona e phahameng ea hona joale le ho hanyetsa motlakase. Leha ho le joalo, tsoelo-pele ea theknoloji ea MOS e qholotsa khopolo ena.

Mabapi le ts'ebetso ea ts'ebeliso, merero ea sejoale-joale ea BMS e thehiloeng ho MOS e se e ts'ehetsa maqhubu ho tloha ho 200A ho isa ho 800A, e etsang hore e tšoanele maemo a fapaneng a hajoale. Tsena li kenyelletsa lithuthuthu tsa motlakase, likariki tsa kolofo, likoloi tse tsamaeang hohle, esita le lits'ebetso tsa leoatleng, moo lipotoloho tsa ho emisa khafetsa le liphetoho tse matla li hlokang taolo e nepahetseng ea hajoale. Ka mokhoa o ts'oanang, mecheng ea thepa e kang forklift le liteishene tsa ho tjhaja mehala, litharollo tsa MOS li fana ka kopanyo e phahameng le linako tsa karabelo tse potlakileng.

Ts'ebetsong, litsamaiso tse thehiloeng ho li-relay li kenyelletsa kopano e rarahaneng e nang le likarolo tse ling joalo ka li-transformer tsa hajoale le mehloli ea matla a kantle, e hlokang wiring ea litsebi le solder. Sena se eketsa kotsi ea ho ba le mathata a ho rekisa, a lebisang ho hloleheng joalo ka ho tima ha motlakase kapa ho chesa ho feta nako. Ka lehlakoreng le leng, merero ea MOS e na le meralo e kopaneng e nolofatsang ho kenya le ho hlokomela. Mohlala, ho koaloa ha relay ho hloka taolo e tiileng ea tatellano ho qoba tšenyo ea karolo, ha MOS e lumella ho khaola ka kotloloho ka litefiso tse fokolang tsa liphoso. Litsenyehelo tsa tlhokomelo ea MOS li tlase ho 68-75% selemo le selemo ka lebaka la likarolo tse fokolang le ho lokisoa kapele.

Tlhahlobo ea litšenyehelo e senola hore le hoja li-relay li bonahala li le theko e tlaase qalong, litšenyehelo tsohle tsa bophelo ba MOS li tlaase. Sistimi ea ho fetisoa e hloka likarolo tse ling (mohlala, litšepe tsa ho tima mocheso), litšenyehelo tse phahameng tsa basebetsi bakeng sa ho lokisa liphoso, 'me li sebelisa ≥5W ea matla a tsoelang pele, athe MOS eona e sebelisa ≤1W. Likhokahano tsa li-relay le tsona li felloa ke matla ka potlako, 'me li hloka tlhokomelo e eketsehileng makhetlo a 3-4 ka selemo.

Ho latela ts'ebetso, li-relay li na le karabelo e liehang (10-20ms) 'me li ka baka "hohoelea" ha matla nakong ea liphetoho tse potlakileng joalo ka ho phahamisa forklift kapa braking ea tšohanyetso, likotsi tse ntseng li eketseha joalo ka ho feto-fetoha ha motlakase kapa liphoso tsa sensor. Ka lehlakoreng le leng, MOS e arabela ka 1-3ms, e fana ka phepelo ea matla e bonolo le nako e telele ea bophelo ntle le liaparo tsa 'mele.

Ka bokhuts'oane, merero ea relay e kanna ea lumellana le maemo a tlase a hajoale (<200A) a bonolo, empa bakeng sa lits'ebetso tsa morao-rao, litharollo tsa BMS tse thehiloeng ho MOS li fana ka melemo molemong oa ts'ebeliso, ts'ebeliso ea litšenyehelo, le botsitso. Tšepo ea indasteri ho li-relay hangata e theiloe holim'a liphihlelo tse siiloeng ke nako; ha theknoloji ea MOS e ntse e hola, ke nako ea ho lekola ho latela litlhoko tsa 'nete ho fapana le moetlo.
