Ukusetshenziswa kwebhethri le-lithium kuye kwanda kuzo zonke izinhlelo zokusebenza ezahlukahlukene, kusukela kuma-electric wheeler amabili, ama-RV, kanye nezinqola zegalofu kuya ekugcinweni kwamandla ekhaya kanye nokusetha kwezimboni. Eziningi zalezi zinhlelo zisebenzisa ukucushwa kwebhethri okufanayo ukuze kuhlangatshezwane nezidingo zazo zamandla namandla. Ngenkathi ukuxhumana okufanayo kungandisa umthamo futhi kuhlinzeke ngokuphindaphindeka, futhi kwethula ubunzima, okwenza i-Battery Management System (BMS) ibaluleke kakhulu. Ikakhulukazi ku-LiFePO4kanye ne-Li-ionamabhethri, ukufakwa kwe-i-BMS ehlakaniphilekubalulekile ekuqinisekiseni ukusebenza kahle, ukuphepha, kanye nokuphila isikhathi eside.
Amabhethri Ahambisanayo Ezicelweni Zansuku Zonke
Izimoto zikagesi ezinamasondo amabili kanye nezimoto ezincane zokuhamba zivame ukusebenzisa amabhethri e-lithium ukuze zinikeze amandla anele kanye nobubanzi bokusetshenziswa kwansuku zonke. Ngokuxhumanisa amaphakethe amaningi ebhethri ngesikhathi esifanayo,iniingakhuphula amandla wamanje, ivumele ukusebenza okuphezulu kanye namabanga amade. Ngokufanayo, kuma-RV kanye nezinqola zegalofu, ukucushwa kwebhethri elihambisanayo kunikeza amandla adingekayo kokubili izinhlelo zokuqhuba kanye nezokusiza, njengezibani kanye nezinto zikagesi.
Ezinhlelweni zokugcina amandla zasekhaya kanye nasezinhlelweni ezincane zezimboni, amabhethri e-lithium axhunywe ngendlela efanayo avumela ukugcina amandla engeziwe ukusekela izidingo zamandla ezahlukahlukene. Lezi zinhlelo ziqinisekisa ukuhlinzekwa kwamandla okuzinzile ngesikhathi sokusetshenziswa okuphezulu noma ezimweni ezingaphandle kwegridi.
Kodwa-ke, ukuphatha amabhethri amaningi e-lithium ngesikhathi esisodwa akulula ngenxa yokuthi kungenzeka kube nokungalingani nezinkinga zokuphepha.
Indima Ebalulekile Ye-BMS Ezinhlelweni Zebhethri Ezihambisanayo
Ukuqinisekisa Ibhalansi Ye-Voltage Neyamanje:Ekucushweni okufanayo, iphakethe ngalinye lebhethri le-lithium kumele ligcine izinga elifanayo le-voltage ukuze lisebenze kahle. Ukwehluka kwe-voltage noma ukumelana kwangaphakathi phakathi kwamaphakethe kungaholela ekusabalaleni kwamanje okungalingani, kanti amanye amaphakethe asebenza ngokweqile kanti amanye asebenza kabi. Lokhu kungalingani kungaholela ngokushesha ekwehleni kokusebenza noma ngisho nasekuhlulekeni. I-BMS iqapha futhi ilinganisele njalo i-voltage yephakethe ngalinye, iqinisekisa ukuthi isebenza kahle ukuze ikhuphule ukusebenza kahle nokuphepha.
Ukuphathwa Kokuphepha:Ukuphepha kuyinto ebaluleke kakhulu, Ngaphandle kwe-BMS, amaphakethe ahambisanayo angabhekana nokushaja ngokweqile, ukukhipha ngokweqile, noma ukushisa ngokweqile, okungaholela ekubalekeni kokushisa—isimo esingaba yingozi lapho ibhethri lingasha noma liqhume khona. I-BMS isebenza njengesivikelo, iqapha izinga lokushisa lephakethe ngalinye, i-voltage, kanye nogesi. Ithatha izinyathelo zokulungisa njengokunqamula ishaja noma umthwalo uma noma yiliphi iphakethe lidlula imikhawulo yokusebenza ephephile.
Ukwandisa Isikhathi Sokuphila Sebhethri:Kuma-RV, isitoreji samandla asekhaya, amabhethri e-lithium amelela utshalomali olukhulu. Ngokuhamba kwesikhathi, umehluko emazingeni okuguga kwamaphakethe ngamanye ungaholela ekungalingani ohlelweni olufanayo, kunciphisa isikhathi sokuphila sebhethri. I-BMS isiza ekunciphiseni lokhu ngokulinganisela isimo sokushaja (i-SOC) kuwo wonke amaphakethe. Ngokuvimbela noma yiliphi iphakethe elilodwa ukuthi lisetshenziswe ngokweqile noma lishajwe ngokweqile, i-BMS iqinisekisa ukuthi wonke amaphakethe aguga ngokulinganayo, ngaleyo ndlela andise impilo yebhethri iyonke.
Ukuqapha Isimo Secala (i-SOC) kanye Nesimo Sezempilo (i-SOH):Ezinhlelweni zokusebenza ezifana nokugcina amandla ekhaya noma izinhlelo zamandla ze-RV, ukuqonda i-SoC kanye ne-SoH yamaphakethe ebhethri kubalulekile ekuphathweni kwamandla okuphumelelayo. I-BMS ehlakaniphile inikeza idatha yesikhathi sangempela ngokushaja kanye nesimo sempilo sephakethe ngalinye ekucushweni okufanayo. Izimboni eziningi ze-BMS zanamuhla,njenge-DALY BMSzinikeza izixazululo ze-BMS ezihlakaniphile ezithuthukisiwe ngezinhlelo zokusebenza ezizinikele. Lezi zinhlelo zokusebenza ze-BMS zivumela abasebenzisi ukuthi baqaphe kude izinhlelo zabo zebhethri, bathuthukise ukusetshenziswa kwamandla, bahlele ukulungiswa, futhi bavimbele ukungasebenzi okungalindelekile.
Ngakho-ke, ingabe amabhethri ahambisanayo ayayidinga i-BMS? Impela. I-BMS iyiqhawe elingakadunyiswa elisebenza buthule ngemuva kwezigcawu, liqinisekisa ukuthi izinhlelo zethu zansuku zonke ezihlanganisa amabhethri ahambisanayo zisebenza kahle futhi ngokuphephile.
