Nkhani - Relay vs MOS BMS Kufananitsa: Upangiri Wakufunsira Kwapamwamba Kwambiri

Posankhaa Battery Management System (BMS) pamapulogalamu apamwamba kwambirimonga ma forklift amagetsi ndi magalimoto oyendera alendo, chikhulupiliro chofala ndichakuti ma relay ndi ofunikira pamafunde opitilira 200A chifukwa cha kulekerera kwawo kwakukulu komanso kukana kwamagetsi. Komabe, kupita patsogolo kwaukadaulo wa MOS kukutsutsa lingaliro ili.

Pankhani yokhudzana ndi kugwiritsa ntchito, machitidwe amakono a BMS a MOS tsopano amathandizira mafunde kuchokera ku 200A mpaka 800A, kuwapangitsa kukhala oyenera pazochitika zosiyanasiyana zamasiku ano. Izi zikuphatikizapo njinga zamoto zamagetsi, ngolo za gofu, magalimoto amtundu uliwonse, ngakhalenso ntchito zapamadzi, pomwe kuyimitsa koyambira pafupipafupi komanso kusintha kwamphamvu kumafunikira kuwongolera kwanthawi zonse. Mofananamo, m'makina opangira zinthu monga ma forklift ndi malo opangira mafoni, mayankho a MOS amapereka kuphatikiza kwakukulu komanso nthawi yoyankha mwachangu.

Pogwira ntchito, makina opangira ma relay amaphatikiza kuphatikiza kovutirapo komwe kumakhala ndi zina zowonjezera monga zosinthira zamakono ndi magwero amagetsi akunja, zomwe zimafuna waya waluso ndi soldering. Izi zimawonjezera chiwopsezo cha zovuta za soldering, zomwe zimabweretsa kulephera monga kuzimitsa kwa magetsi kapena kutenthedwa pakapita nthawi. Mosiyana ndi izi, madongosolo a MOS amakhala ndi mapangidwe ophatikizika omwe amathandizira kukhazikitsa ndi kukonza mosavuta. Mwachitsanzo, kutseka kwa relay kumafuna kuwongolera mosamalitsa kuti apewe kuwonongeka kwa gawo, pomwe MOS imalola kudulidwa kwachindunji ndi zolakwika zochepa. Ndalama zolipirira MOS zimatsika ndi 68-75% pachaka chifukwa cha magawo ochepa komanso kukonza mwachangu.

Kuwunika kwamitengo kumawonetsa kuti ngakhale kubweza kumawoneka kotsika mtengo, mtengo wamoyo wonse wa MOS ndiwotsika. Makina otumizirana mauthenga amafunikira zina zowonjezera (mwachitsanzo, zotchingira kutentha), kukwera mtengo kwa ogwira ntchito pakuwongolera, komanso kumawononga ≥5W yamphamvu yosalekeza, pomwe MOS imawononga ≤1W. Zolumikizana ndi ma relay zimathanso mwachangu, zomwe zimafunikira kukonzanso ka 3-4 pachaka.

Mwanzeru, ma relay amayankha pang'onopang'ono (10-20ms) ndipo angayambitse "chibwibwi" mphamvu pakasintha mwachangu ngati kukweza ma forklift kapena braking mwadzidzidzi, kuonjezera ngozi monga kusinthasintha kwa magetsi kapena zolakwika za sensor. Mosiyana ndi izi, MOS imayankha mu 1-3ms, kupereka mphamvu yoperekera mphamvu komanso moyo wautali popanda kuvala kukhudzana ndi thupi.

Mwachidule, masinthidwe otumizirana makiyi amatha kugwirizana ndi zochitika zotsika (<200A) zosavuta, koma pazogwiritsa ntchito zamakono, mayankho a MOS-based BMS amapereka maubwino osavuta kugwiritsa ntchito, kugwiritsa ntchito bwino ndalama, komanso kukhazikika. Kudalira kwa makampani pa ma relay nthawi zambiri kumachokera ku zochitika zakale; ndi luso la MOS likukhwima, ndi nthawi yoti muwunikire kutengera zosowa zenizeni osati mwambo.
