Mabatire a lithiamu a polima, omwe amadziwikanso kuti mabatire a lithiamu polima kapena mabatire a LiPo, ayamba kutchuka m'mafakitale osiyanasiyana chifukwa cha kuchuluka kwa mphamvu zawo, kapangidwe kake kopepuka, komanso kuwongolera chitetezo.Komabe, monga batire ina iliyonse, mabatire a lithiamu a polymer nthawi zina amatha kukumana ndi zovuta monga kusalinganika kwa batire.Nkhaniyi ikufuna kukambirana zomwe zimayambitsa kusamvana kwamagetsi a batri mu alithiamu polima batire paketindi kupereka njira zothandiza kuthana nazo.
Kusalinganika kwa magetsi a batire kumachitika pamene milingo ya batire ya batire ya lithiamu polima imasinthasintha, zomwe zimapangitsa kugawa mphamvu mosiyanasiyana.Kusalinganika uku kumatha chifukwa cha zinthu zingapo, kuphatikiza kusiyanasiyana kwamphamvu kwa batri, kukalamba, kusiyanasiyana kopanga, komanso kagwiritsidwe ntchito kake.Kukasiyidwa, kusalinganika kwa batire kumatha kuchepetsa magwiridwe antchito a batri, kuchepetsa mphamvu ya paketi ya batri, komanso kusokoneza chitetezo.
Kuti muthane ndi kusalinganika bwino kwa batire, njira zingapo zitha kukhazikitsidwa.Choyamba, ndikofunikira kusankha zapamwamba kwambiripolymer lithiamu batiremaselo ochokera kwa opanga odziwika.Maselowa amayenera kukhala ndi mawonekedwe amagetsi osasinthasintha ndikutsata njira zowongolera bwino kuti achepetse mwayi wa kusalinganika kwamagetsi komwe kumachitika poyamba.
Chachiwiri,machitidwe oyenera a batire (BMS) ndi ofunikira pakuwunika ndikuwongolera kuchuluka kwamagetsi mkatipakiti ya batri ya lithiamu polymer.BMS imawonetsetsa kuti batire iliyonse imakhala yolipitsidwa ndikutulutsidwa mofanana, kupewa zovuta zilizonse.BMS imayesa mosalekeza voteji ya selo iliyonse, imazindikiritsa kusalinganika kulikonse, ndikugwiritsa ntchito njira zofananira kuti zigwirizane ndi ma voltage.Kulinganiza kumatha kutheka kudzera munjira zogwira ntchito kapena zopanda pake.
Kulinganiza kogwira kumaphatikizapo kugawanso magetsi ochulukirapo kuchokera ku ma cell-voltage apamwamba kupita ku ma cell-voltage otsika, kuwonetsetsa kuti ma voltage amtundu wofananawo ali nawo.Njirayi ndi yothandiza kwambiri koma imafuna maulendo owonjezera, kuonjezera mtengo ndi zovuta.Komano, kusanja kosalekeza, nthawi zambiri kumadalira ma resistors kuti atulutse ndalama zambiri kuchokera ku ma cell-voltage apamwamba.Ngakhale kuti sizovuta komanso zotsika mtengo, kugwirizanitsa pang'onopang'ono kungathe kutaya mphamvu zambiri monga kutentha, zomwe zimapangitsa kuti zikhale zovuta.
Komanso,Kukonzekera kwapaketi ya batri nthawi zonse ndikofunikira kuti mupewe komanso kuthana ndi kusalinganika kwamagetsi a batri.Izi zikuphatikizanso kuyang'anira mphamvu ya batire pa paketi yonse komanso ma voltages amtundu uliwonse pafupipafupi.Ngati kusagwirizana kulikonse kwamagetsi kuzindikirika, kulipiritsa kapena kutulutsa ma cell omwe akhudzidwa payekhapayekha kungathandize kukonza vutolo.Kuphatikiza apo, ngati selo likuwonetsa kusiyana kwakukulu kwamagetsi poyerekeza ndi ena, lingafunike kusinthidwa.
Komanso,Kulipiritsa moyenera ndi kutulutsa mphamvu ndikofunikira kuti mphamvu yamagetsi ikhale yoyenera mkati mwa alithiamu polima batire paketi.Kuchulukirachulukira kapena kutulutsa kwambiri ma cell amatha kuyambitsa kusalinganika kwamagetsi.Chifukwa chake, ndikofunikira kugwiritsa ntchito ma charger omwe amapangidwira mabatire a polymer lithiamu omwe amapereka magetsi komanso malamulo apano.Kuphatikiza apo, kupewa kutulutsa kwakuya komanso kudzaza batriyo mochulukira kumawonetsetsa kuti ma voltages a ma cell azikhala okhazikika pakapita nthawi.
Pomaliza, ngakhale kuti kusagwirizana kwa batire ya batri ndi vuto lomwe lingakhalepo mu mapaketi a batri a lithiamu polima, kusankha koyenera kwa ma cell a batri apamwamba kwambiri, kukhazikitsa njira yodalirika yoyendetsera batire, kukonza nthawi zonse, komanso kutsatira njira zolipirira moyenera kungachepetse nkhaniyi.Mabatire a lithiamu a polymer amapereka zabwino zambiri, ndipo mosamala, amatha kupereka mphamvu zotetezeka komanso zogwira mtima pazogwiritsa ntchito zosiyanasiyana mtsogolo.
