Relay vs. MOS kuri BMS ifite umuriro mwinshi: Ni iyihe nziza ku modoka zikoresha amashanyarazi?

Mu gihe uhitamoSisitemu yo gucunga batiri (BMS)​​ikoreshwa mu gukoresha ingufu nyinshiKimwe n'imodoka zitwara amashanyarazi n'izitwara abantu, abantu benshi bemera ko relays ari ingenzi ku miyoboro y'amashanyarazi iri hejuru ya 200A bitewe n'uko ifite ubushobozi bwo kwihanganira umuriro mwinshi ndetse no kudakomera ku muvuduko w'amashanyarazi. Ariko, iterambere mu ikoranabuhanga rya MOS riravuguruza iki gitekerezo.

Ku bijyanye n'uburyo bwo gukoresha, gahunda za BMS zigezweho zishingiye kuri MOS ubu zishyigikira imiyoboro y'amashanyarazi kuva kuri 200A kugeza kuri 800A, bigatuma ikoreshwa mu bihe bitandukanye by'amashanyarazi menshi. Ibi birimo moto zikoresha amashanyarazi, imodoka zo mu bwoko bwa golf, imodoka zo mu bwoko bwose, ndetse n'izikoreshwa mu mazi, aho imiyoboro ihoraho yo guhagarara no guhindura umutwaro bisaba kugenzura neza umuriro. Mu buryo nk'ubwo, mu mashini zitwara abagenzi nka forklifts na stations zikoresha amashanyarazi zigendanwa, ibisubizo bya MOS bitanga uburyo bwo guhuza imbaraga no gusubiza vuba.
Mu mikorere, sisitemu zishingiye ku gusimburana zisaba guteranya ibintu bikomeye hamwe n'ibindi bice nka transformateur zikoresha ubu n'amasoko y'amashanyarazi yo hanze, bigasaba insinga z'umwuga no gutwikira. Ibi byongera ibyago byo kugira ibibazo byo gutwikirana, bigatera kwangirika nko kubura amashanyarazi cyangwa gushyuha cyane uko igihe kigenda gihita. Mu buryo bunyuranye, gahunda za MOS zifite imiterere ihuriweho yoroshya gushyiraho no kubungabunga. Urugero, kuzimya gusimburana bisaba kugenzura cyane urukurikirane rw'ibice kugira ngo hirindwe kwangirika kw'ibice, mu gihe MOS yemerera guhagarara mu buryo butaziguye hamwe n'umuvuduko muto w'amakosa. Ikiguzi cyo kubungabunga MOS kiri hasi ho 68-75% buri mwaka bitewe n'ibice bike no gusana vuba.
BMS ifite umuvuduko mwinshi
BMS yo gutwara abantu
Isesengura ry'ibiciro rigaragaza ko nubwo relay zisa n'izihendutse mu ntangiriro, ikiguzi cy'ubuzima bwose bwa MOS kiri hasi. Sisitemu zo relay zikenera ibikoresho by'inyongera (urugero: utubari two gukwirakwiza ubushyuhe), ikiguzi kinini cy'abakozi mu gukemura ibibazo, kandi zikoresha ≥5W z'ingufu zihoraho, mu gihe MOS ikoresha ≤1W. Ibyuma byo relay nabyo birashira vuba, bigasaba kwitabwaho inshuro 3-4 buri mwaka.
Mu bijyanye n'imikorere, relays igira igisubizo gito (10-20ms) kandi ishobora gutera "kuzunga" kw'ingufu mu gihe cy'impinduka zihuse nko guterura forklift cyangwa gufunga feri mu buryo butunguranye, byongera ibyago nko guhinduka k'amashanyarazi cyangwa amakosa ya sensor. Mu buryo bunyuranye, MOS isubiza muri 1-3ms, itanga amashanyarazi yoroshye kandi igakomeza igihe kirekire idakora ku mubiri.

Muri make, gahunda zo gutwara abantu zirashobora kuba zijyanye n'ibintu byoroshye bifite umuvuduko muto (<200A), ariko ku bikoresho bifite umuvuduko mwinshi, ibisubizo bya BMS bishingiye kuri MOS bitanga inyungu mu koroshya ikoreshwa, gukoresha neza ikiguzi, no kudahungabana. Kwishingikiriza ku bikoresho bitwara abantu akenshi bishingiye ku bunararibonye budashaje; ikoranabuhanga rya MOS rimaze gukura, ni cyo gihe cyo gusuzuma hashingiwe ku byo ukeneye aho kuba ku muco gakondo.
