Izindaba - I-Relay vs MOS BMS Ukuqhathanisa: Umhlahlandlela Wezicelo Wamanje Ophakeme

Lapho ukhethai-Battery Management System (BMS)yezinhlelo zokusebenza zamanjenjengama-forklift kagesi kanye nezimoto zokuvakasha, inkolelo evamile ukuthi ama-relay abalulekile kuma-currents angaphezu kuka-200A ngenxa yokubekezelelana kwawo okuphezulu kwamanje kanye nokumelana nomthamo. Kodwa-ke, ukuthuthuka kobuchwepheshe be-MOS kuwubekela inselele lo mbono.

Ngokuphathelene nokufakwa kwesicelo, izikimu zesimanje ze-BMS ezisekelwe ku-MOS manje zisekela imisinga ukusuka ku-200A ukuya ku-800A, okuzenza zifanelekele izimo ezihlukahlukene zamanje. Lokhu kufaka phakathi izithuthuthu zikagesi, izinqola zegalofu, izimoto ezihamba kuzo zonke izindawo, ngisho nezinhlelo zokusebenza zasolwandle, lapho imijikelezo yokuqala yokuma kanye noshintsho lwemithwalo eguqukayo ludinga ukulawula kwamanje okunembile. Ngokufanayo, emishinini yezokuthutha efana ne-forklift neziteshi zokushaja eziphathwayo, izixazululo ze-MOS zinikeza ukuhlanganiswa okuphezulu kanye nezikhathi zokuphendula ngokushesha.

Ngokusebenza, amasistimu asekelwe ku-relay ahlanganisa ukuhlangana okuyinkimbinkimbi nezingxenye ezengeziwe ezifana neziguquli zamanje kanye nemithombo yamandla yangaphandle, edinga izintambo ezichwepheshile kanye ne-soldering. Lokhu kwandisa ubungozi bezinkinga ze-virtual soldering, okuholela ekuhlulekeni njengokucisha kukagesi noma ukushisa ngokweqile ngokuhamba kwesikhathi. Ngokuphambene, izikimu ze-MOS zinemiklamo ehlanganisiwe eyenza ukufakwa nokugcinwa kube lula. Isibonelo, ukuvala shaqa kwe-relay kudinga ukulawula okuqinile kokulandelana ukuze kugwenywe ukulimala kwengxenye, kuyilapho i-MOS ivumela ukunqamuka okuqondile ngamaphutha amancane. Izindleko zokunakekela ze-MOS ziphansi ngo-68-75% ngonyaka ngenxa yezingxenye ezimbalwa nokulungiswa ngokushesha.

Ukuhlaziywa kwezindleko kuveza ukuthi nakuba ukudluliselwa kubonakala kushibhile ekuqaleni, izindleko eziphelele zomjikelezo wokuphila we-MOS ziphansi. Amasistimu okudlulisa adinga izingxenye ezengeziwe (isb, amabha okukhipha ukushisa), izindleko eziphezulu zabasebenzi zokulungisa amaphutha, futhi zisebenzisa u-≥5W wamandla aqhubekayo, kuyilapho i-MOS isebenzisa ≤1W. Oxhumana nabo be-relay nabo baguga ngokushesha, okudinga ukunakekelwa okuphindwe ka-3-4 ngonyaka.

Ngokokusebenza okuhlakaniphile, ama-relay anokusabela okunensayo (10-20ms) futhi angabangela amandla "ukungingiza" phakathi nezinguquko ezisheshayo njengokuphakanyiswa kwe-forklift noma ukubhuleka kungazelelwe, okwandisa izingozi njengokuguquguquka kwe-voltage noma amaphutha enzwa. Ngokuphambene, i-MOS iphendula ngo-1-3ms, ihlinzeka ngokulethwa kwamandla okushelelayo nempilo ende ngaphandle kokugqokwa kokuthintana ngokomzimba.

Kafushane, izikimu zokudlulisela zingase zivumelane nezimo ezilula zamanje (<200A), kodwa ezinhlelweni zamanje, izixazululo ze-BMS ezisekelwe ku-MOS zinikeza izinzuzo zokusebenzisa kalula, ukusebenza kahle kwezindleko, nokuzinza. Ukuthembela kwemboni kuma-relay ngokuvamile kusekelwe kokuhlangenwe nakho okudlulelwe yisikhathi; ngobuchwepheshe be-MOS bukhula, yisikhathi sokuhlola ngokusekelwe ezidingweni zangempela kunesiko.
