Izindaba - Ukuqhathaniswa kwe-Relay vs MOS BMS: Umhlahlandlela Wezicelo Ezisebenza Kakhulu

Uma ukhethaUhlelo Lokuphatha Ibhethri (i-BMS) lwezinhlelo zokusebenza zamandla aphezulunjenge-forklift kagesi kanye nezimoto zokuvakasha, inkolelo evamile ukuthi ama-relay abalulekile kuma-current angaphezu kuka-200A ngenxa yokubekezelela kwawo okuphezulu kwamanje kanye nokumelana ne-voltage. Kodwa-ke, intuthuko kwezobuchwepheshe be-MOS iyinselele le mbono.

Ngokuphathelene nokufakwa kwesicelo, izinhlelo ze-BMS zesimanje ezisekelwe ku-MOS manje zisekela imisinga kusukela ku-200A kuya ku-800A, okwenza zifaneleke ezimweni ezahlukahlukene zamandla aphezulu. Lokhu kufaka phakathi izithuthuthu zikagesi, izinqola zegalofu, izimoto ezihamba yonke indawo, ngisho nezinhlelo zokusebenza zasolwandle, lapho imijikelezo evamile yokuma kanye nezinguquko zomthwalo oguqukayo zidinga ukulawulwa kwamandla okuqondile. Ngokufanayo, emishinini yezokuthutha efana nama-forklift kanye neziteshi zokushaja zeselula, izixazululo ze-MOS zinikeza ukuhlanganiswa okuphezulu kanye nezikhathi zokuphendula okusheshayo.

Ngokusebenza, izinhlelo ezisekelwe ku-relay zihilela ukuhlanganiswa okuyinkimbinkimbi ngezingxenye ezengeziwe ezifana nama-transformer amanje kanye nemithombo yamandla yangaphandle, okudinga izintambo zobungcweti kanye nokunamathisela nge-solder. Lokhu kwandisa ingozi yezinkinga zokunamathisela nge-solder, okuholela ekuhlulekeni njengokucima kukagesi noma ukushisa ngokweqile ngokuhamba kwesikhathi. Ngokuphambene nalokho, izinhlelo ze-MOS zinemiklamo ehlanganisiwe eyenza kube lula ukufakwa nokugcinwa. Isibonelo, ukuvala i-relay kudinga ukulawulwa okuqinile kokulandelana ukuze kugwenywe ukulimala kwezingxenye, kuyilapho i-MOS ivumela ukunqamuka okuqondile ngamanani amancane amaphutha. Izindleko zokulungisa ze-MOS ziphansi ngo-68-75% minyaka yonke ngenxa yezingxenye ezimbalwa kanye nokulungiswa okusheshayo.

Ukuhlaziywa kwezindleko kwembula ukuthi nakuba ama-relay ebonakala eshibhile ekuqaleni, izindleko zomjikelezo wokuphila kwe-MOS ziphansi. Izinhlelo zama-relay zidinga izingxenye ezengeziwe (isb., imigoqo yokusabalalisa ukushisa), izindleko eziphezulu zomsebenzi zokulungisa amaphutha, futhi zisebenzisa amandla angu-≥5W aqhubekayo, kuyilapho i-MOS isebenzisa angu-≤1W. Oxhumana nabo be-relay nabo baguga ngokushesha, okudinga ukulungiswa okuphindwe kathathu kuya kane ngonyaka.

Ngokusebenza kahle, ama-relay anempendulo ehamba kancane (10-20ms) futhi angabangela "ukungingiza" kwamandla ngesikhathi sokushintsha okusheshayo njengokuphakamisa i-forklift noma ukubhuleka okungazelelwe, okwandisa izingozi ezifana nokushintshashintsha kwamandla noma amaphutha ezinzwa. Ngokuphambene nalokho, i-MOS iphendula nge-1-3ms, ihlinzeka ngokulethwa kwamandla okubushelelezi kanye nokuphila isikhathi eside ngaphandle kokuphazamiseka kokuthintana ngokomzimba.

Ngamafuphi, izinhlelo zokudlulisa zingase zivumelane nezimo ezilula ze-low-current (<200A), kodwa ngezinhlelo zokusebenza ze-high-current, izixazululo ze-BMS ezisekelwe ku-MOS zinikeza izinzuzo zokusetshenziswa kalula, ukusebenza kahle kwezindleko, kanye nokuzinza. Ukuthembela kwemboni kuma-relay kuvame ukusekelwe kokuhlangenwe nakho okudala; njengoba ubuchwepheshe be-MOS buvuthwa, sekuyisikhathi sokuhlola ngokusekelwe ezidingweni zangempela kunesiko.
