Iindaba - Uthelekiso lwe-Relay vs MOS BMS: Isikhokelo seZicelo eziKhawulezayo

Xa ukhethaInkqubo yoLawulo lweBhetri (i-BMS) yezicelo ezisebenzisa amandla aphezulunjengee-forklifts zombane kunye nezithuthi zokhenketho, kukho inkolelo eqhelekileyo yokuba ii-relay zibalulekile kwi-currents ezingaphezulu kwe-200A ngenxa yokunyamezela kwazo okuphezulu kombane kunye nokumelana ne-voltage. Nangona kunjalo, ukuqhubela phambili kwitekhnoloji ye-MOS kuyayiphikisa le ngcamango.

Ngokuphathelele ukugutyungelwa kwesicelo, iinkqubo zeBMS ezisekelwe kwiMOS zanamhlanje ngoku zixhasa imisinga ukusuka kwi-200A ukuya kwi-800A, nto leyo eyenza ukuba ifaneleke kwiimeko ezahlukeneyo zombane ophezulu. Ezi ziquka iibhayisekile zombane, iinqwelo zegalufa, izithuthi ezihamba kuzo zonke iindawo, kwanezicelo zaselwandle, apho imijikelo yokuma rhoqo kunye notshintsho lomthwalo olutshintshayo lufuna ulawulo oluchanekileyo lwamandla. Ngokufanayo, kwiimashini zothutho ezifana neefolokhwe kunye nezikhululo zokutshaja ezihambayo, izisombululo zeMOS zibonelela ngokuhlanganiswa okuphezulu kunye namaxesha okuphendula ngokukhawuleza.

Ngokusebenza, iinkqubo ezisekelwe kwi-relay ziquka ukuhlanganiswa okuntsonkothileyo kunye nezinto ezongezelelweyo ezifana nee-transformers zangoku kunye nemithombo yamandla yangaphandle, ezifuna iingcingo zobungcali kunye ne-soldering. Oku kwandisa umngcipheko weengxaki ze-soldering ezibonakalayo, ezikhokelela ekusileleni njengokucima kombane okanye ukugqithisa ngokuhamba kwexesha. Ngokwahlukileyo koko, izicwangciso ze-MOS zibonisa uyilo oludibeneyo olulula ukufakelwa kunye nokugcinwa. Umzekelo, ukuvalwa kwe-relay kufuna ulawulo oluqinileyo lolandelelwano ukuze kuthintelwe umonakalo wecandelo, ngelixa i-MOS ivumela ukunqunyulwa ngokuthe ngqo kunye namazinga amancinci eempazamo. Iindleko zokugcinwa kwe-MOS ziphantsi ngama-68-75% ngonyaka ngenxa yeendawo ezimbalwa kunye nokulungiswa okukhawulezileyo.

Uhlalutyo lweendleko lubonisa ukuba nangona iirelay zibonakala zingabizi ekuqaleni, ixabiso elipheleleyo le-MOS liphantsi. Iinkqubo zerelay zifuna izinto ezongezelelweyo (umz., iibha zokusasaza ubushushu), iindleko eziphezulu zomsebenzi zokulungisa iingxaki, kwaye zisebenzisa amandla angapheliyo angama-≥5W, ngelixa i-MOS isebenzisa i-≤1W. Izixhobo zerelay nazo ziyaphela ngokukhawuleza, zifuna ukulungiswa okuphindwe kathathu ukuya kane ngonyaka.

Ngokwendlela esebenza ngayo, iirelay ziphendula kancinci (10-20ms) kwaye zinokubangela "ukutsiba" kwamandla ngexesha lotshintsho olukhawulezileyo olufana nokuphakamisa i-forklift okanye ukubhuleka ngequbuliso, okwandisa umngcipheko ofana nokuguquguquka kwevolthi okanye iimpazamo zesensor. Ngokwahlukileyo koko, i-MOS iphendula kwi-1-3ms, ibonelela ngokuhanjiswa kwamandla okuthambileyo kunye nobomi obude ngaphandle kokuguguleka kokuthintana ngokomzimba.

Ngamafutshane, izicwangciso zokudlulisa amandla zingafanela iimeko ezilula zombane ophantsi (<200A), kodwa kwizicelo zombane ophantsi, izisombululo ze-BMS ezisekelwe kwi-MOS zibonelela ngeengenelo zokulula kokusetyenziswa, ukusebenza kakuhle kweendleko, kunye nokuzinza. Ukuxhomekeka kweshishini kwiirelay kudla ngokusekwe kumava aphelelwe lixesha; njengoko ubuchwepheshe be-MOS bukhula, lixesha lokuvavanya ngokusekelwe kwiimfuno zokwenyani kunokuba kube sisithethe.
