Nkhani - Mawaya Oyesera a BMS: Kuwunika Voltage ya Mabatire Aakulu

Mawaya Oyesera a BMS: Momwe Mawaya Oonda Amayang'anira Molondola Maselo Akuluakulu a Batri

Mu machitidwe oyang'anira mabatire, funso lofala limabuka: kodi mawaya opyapyala oyesa zitsanzo angagwire bwanji ntchito yowunikira magetsi a maselo akuluakulu popanda mavuto? Yankho lili mu kapangidwe koyambira ka ukadaulo wa Battery Management System (BMS). Mawaya oyesa zitsanzo amaperekedwa pakupeza magetsi, osati kutumiza magetsi, mofanana ndi kugwiritsa ntchito multimeter kuyeza magetsi a batire polumikizana ndi ma terminal.

Pa paketi ya batire ya mndandanda wa 20, chogwirira cha zitsanzo nthawi zambiri chimakhala ndi mawaya 21 (20 positives + 1 common negative). Peyala iliyonse yoyandikana imayesa voltage ya selo limodzi. Njirayi si yoyezera yogwira ntchito koma njira yotumizira chizindikiro chopanda ntchito. Mfundo yaikulu imaphatikizapo kuletsa kwakukulu kolowera, komwe kumakoka mphamvu yochepa kwambiri—nthawi zambiri ma microamperes (μA)—zomwe ndi zochepa poyerekeza ndi mphamvu ya selo. Malinga ndi lamulo la Ohm, ndi mafunde a μA-level ndi kukana kwa waya kwa ma ohms ochepa, kutsika kwa voltage kumangokhala ma microvolts (μV), kuonetsetsa kuti kulondola sikukhudza magwiridwe antchito.

Komabe, kuyika koyenera ndikofunikira kwambiri. Kuyika mawaya kolakwika—monga kulumikizana kumbuyo kapena kudutsa—kungayambitse zolakwika pamagetsi, zomwe zimapangitsa kuti chitetezo cha BMS chisaganizidwe molakwika (monga, zoyambitsa za over/under-voltage). Milandu yoopsa ingayambitse mawaya ku ma voltage okwera, zomwe zimapangitsa kuti kutentha kwambiri, kusungunuka, kapena kuwonongeka kwa dera la BMS. Nthawi zonse onetsetsani kuti mawayawo akuyenda bwino musanalumikize BMS kuti mupewe zoopsa izi. Chifukwa chake, mawaya opyapyala ndi okwanira kutengera ma voltage chifukwa cha kufunikira kwa magetsi ochepa, koma kuyika kolondola kumatsimikizira kudalirika.
