Nkhani - Kuyerekeza kwa Relay vs MOS BMS: Buku Lothandizira Mapulogalamu Amphamvu Kwambiri

MukasankhaDongosolo Loyang'anira Mabatire (BMS)la mapulogalamu amphamvu kwambiriMonga ma forklift amagetsi ndi magalimoto oyendera, anthu ambiri amakhulupirira kuti ma relay ndi ofunikira kwambiri pamafunde opitilira 200A chifukwa cha kupirira kwawo kwakukulu kwamagetsi komanso kukana kwamagetsi. Komabe, kupita patsogolo kwa ukadaulo wa MOS kukutsutsa lingaliro ili.

Ponena za momwe ntchito ikugwiritsidwira ntchito, njira zamakono za BMS zochokera ku MOS tsopano zimathandizira mafunde kuyambira 200A mpaka 800A, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mafunde osiyanasiyana amagetsi amphamvu. Izi zikuphatikizapo njinga zamoto zamagetsi, ngolo za gofu, magalimoto oyenda pansi, komanso ntchito zapamadzi, komwe ma cycle oyambira nthawi zambiri komanso kusintha kwa katundu wofunikira kumafuna kuwongolera bwino mafunde. Mofananamo, mumakina oyendetsera zinthu monga ma forklift ndi malo ochapira mafoni, njira za MOS zimapereka kulumikizana kwakukulu komanso nthawi yoyankha mwachangu.

Pantchito, makina ogwiritsira ntchito ma relay amaphatikizapo kusonkhana kovuta ndi zida zina monga ma transformer amakono ndi magwero amagetsi akunja, zomwe zimafuna mawaya aukadaulo ndi soldering. Izi zimawonjezera chiopsezo cha mavuto a soldering, zomwe zimapangitsa kuti kulephera monga kuzimitsa magetsi kapena kutenthedwa kwambiri pakapita nthawi. Mosiyana ndi zimenezi, ma MOS schemes ali ndi mapangidwe ophatikizika omwe amasavuta kukhazikitsa ndi kukonza. Mwachitsanzo, kuzimitsa ma relay kumafuna kuwongolera mwamphamvu kuti tipewe kuwonongeka kwa zigawo, pomwe MOS imalola kuletsa mwachindunji ndi kuchuluka kochepa kwa zolakwika. Ndalama zokonzera MOS zimatsika ndi 68-75% pachaka chifukwa cha zida zochepa komanso kukonza mwachangu.

Kusanthula mtengo kukuwonetsa kuti ngakhale kuti ma relay amawoneka otsika mtengo poyamba, mtengo wonse wa moyo wa MOS ndi wotsika. Makina a relay amafunikira zida zowonjezera (monga mipiringidzo yotenthetsera kutentha), ndalama zambiri zogwirira ntchito kuti athetse mavuto, ndipo amagwiritsa ntchito ≥5W ya mphamvu yopitilira, pomwe MOS imagwiritsa ntchito ≤1W. Ma contact a relay amathanso kutha msanga, zomwe zimafuna kukonza kochulukirapo katatu kapena kanayi pachaka.

Poganizira momwe zinthu zilili, ma relay amayankha pang'onopang'ono (10-20ms) ndipo angayambitse "kugwedezeka" kwa mphamvu pakasintha mwachangu monga kukweza forklift kapena kuletsa mwadzidzidzi, zomwe zimawonjezera zoopsa monga kusinthasintha kwa magetsi kapena zolakwika za masensa. Mosiyana ndi zimenezi, MOS imayankha mu 1-3ms, zomwe zimapangitsa kuti mphamvu iperekedwe bwino komanso ikhale ndi moyo wautali popanda kukhudzidwa ndi thupi.

Mwachidule, njira zotumizirana mauthenga zingagwirizane ndi zochitika zosavuta zamagetsi otsika (<200A), koma pa ntchito zamagetsi amphamvu, mayankho a BMS ochokera ku MOS amapereka ubwino wosavuta kugwiritsa ntchito, kugwiritsa ntchito bwino ndalama, komanso kukhazikika. Kudalira kwa makampani pa ma relay nthawi zambiri kumadalira zomwe zachitika kale; ndi ukadaulo wa MOS womwe ukukhwima, ndi nthawi yoti tiwunikenso kutengera zosowa zenizeni osati miyambo.
