Umbhali :Iflowpower-UMboneleli weSikhululo saMandla esiphathwayo
Namhlanje, namhlanje, ezahlukeneyo zobuchwephesha obuphezulu buvela kubomi bethu, zizisa lula kubomi bethu, ke ngaba uyayiqonda le teknoloji iphezulu inokuba nebhalansi yokutshaja? Ibhetri ye-Lithium ion kutshanje Kwimarike, ngenxa yokuphuculwa kwayo okukhulu, isabelo sayo semarike sikhuphuke ngokukhawuleza. Umthamo wokugcina amandla webhetri ye-lithium-ion uyamangalisa kakhulu, nangona kunjalo, umthamo weyunithi yebhetri enye isephantsi kakhulu ukusuka kumbane okanye ukusuka ngoku, kwaye ayikwazi ukuhlangabezana ne-injini ye-hybrid. Ukuhambelana kunye nobuninzi beeseli zebhetri kunokunyusa okwangoku okunikezelwa yibhetri, kwaye ubuninzi beeseli zebhetri kunokunyusa amandla ombane anikezelwa yibhetri.
Ibhalansi yentlawulo (isifinyezo yintlawulo elinganayo) yintlawulo elinganisa iimpawu zebhetri. Ibhekisa kukungalingani kwamandla ombane weterminal yebhetri ngenxa yeyantlukwano yomntu ngamnye kunye nomahluko wobushushu ngenxa yebhetri ngexesha lebhetri. Ukuze kuthintelwe lo mkhwa wokungalingani, i-voltage yokutshaja yepakethe yebhetri kufuneka yongezwe kwaye ibhetri ivuliwe kwaye ihlawulise ukulinganisa iimpawu zebhetri nganye kwiqela lebhetri ye-lithium-ion kunye nokwandisa ubomi bebhetri.
. Ukuba i-voltage idlula uluhlu oluvumelekileyo, ibhetri ye-lithium ion yonakaliswa lula. Ukuba i-voltage idlula umda ophezulu kunye nophantsi (njengomzekelo webhethri ye-ion ye-nanophosphate, i-voltage ye-ion ephantsi ye-2V, i-voltage ye-high limit yi-3.
6V), inokonakalisa ibhetri. Isiphumo ubuncinci sikhawulezisa isantya sokuzikhupha sebhetri. Umbane wokuphuma kwebhetri uzinzile ngaphakathi koluhlu olubanzi lwentlawulo (SOC), kwaye umngcipheko wokutenxa kombane uncinci.
Nangona kunjalo, kuzo zombini iziphelo zoluhlu lokhuseleko, i-ups kunye ne-ducts ye-curve yokutshaja ingumnqantsa. Ngoko ke, njengamanyathelo okuthintela, i-voltage kufuneka ibekwe esweni ngokungqongqo. Ubuchwephesha bokutshaja obulungeleleneyo obuqhelekileyo bubandakanya ukutshaja okulinganayo kokulinganisa ukutshaja, ukulingana okuvulekileyo okunxulumene nokunganyangeki, umndilili webhetri yokulinganisa ukulinganisa ukutshaja, ukutshaja kwe-capacitor equilibrium, ukutshaja okulinganayo kwe-converter-down-down, inductance equalization chargeging, njl.
Ibhetri ye-ion kufuneka idibaniswe kwichungechunge, ibhetri nganye kufuneka ihlawulwe, ngaphandle koko iya kuchaphazela ukusebenza kunye nobomi besethi yonke yeebhetri ngexesha lokusetyenziswa. I-cell ekhoyo ye-lithium-ion ibhetri yokukhusela i-chip ayinayo umsebenzi wokulawula ukutshaja okulinganayo, ukudibanisa i-lithium ion yokukhusela ibhetri ye-chip equalization yokulawula imisebenzi yokulawula ukutshaja kwi-CPU. Iphunyezwe ngonxibelelwano lwe-serial kunye neetshiphusi ezikhuselayo kunye nokwandisa isiphaluka sokukhusela.
Ubunzima kunye nobunzima bokuyila kunciphisa ukusebenza kakuhle kunye nokuthembeka kwenkqubo, kwaye yongeza ukusetyenziswa kwamandla. Indlela yokwenziwa kwesiqhelo: Kwinkqubo yolawulo lwebhetri ngokubanzi, iyunithi yebhetri nganye iqhagamshelwe kuxhathiso lomthwalo ngokutshintsha. Le sekethi yokwenziwa inokukhupha iyunithi enye ekhethiweyo.
Nangona kunjalo, le ndlela isebenza kuphela ekunyusweni kombane weyona bhetri iqinileyo kwimowudi yokucinezela. Ukunciphisa ukusetyenziswa kwamandla, olu hlobo lwesekethe luhlala luvumela ukukhutshwa okuncinci okwangoku okumalunga ne-100 mA, okubangela ukulinganisa kwentlawulo ukuya kuthi ga kwiiyure ezininzi. Xa ukuveliswa kwebhetri ye-lithium-ion ixesha elide, ekubeni ukusetyenziswa kwamandla e-static nganye yeeplate zokukhusela kuyahluka kwaye izinga lokuzikhupha kwibhetri nganye lihlukile, i-voltage yebhetri yentambo nganye ayihambelani.
Ukulinganisa umsebenzi wokulinganisa i-voltage ye-lithium ion ibhetri yepakethe, ukwenzela ukuba umthamo womthamo webhetri unokufezekisa ukusebenza kakuhle kwebhetri yepakethe. Indlela yokulinganisa esebenzayo: Zininzi iindlela ezisebenzayo zokulinganisela kwizinto ezihambelanayo, zonke zinento yokugcina ukuhanjiswa kwamandla. Ukuba i-capacitor isetyenziswe njengento yokugcina, i-capacitor ixhunyiwe kuzo zonke iiseli zebhetri ukuba zibe noluhlu olukhulu lokutshintsha.
Eyona ndlela isebenzayo kukugcina amandla kwimagnethi. Amacandelo aphambili kwisekethe zii-transformers. Iprototype yesekethe iphuhliswa yiQela loPhuhliso lwe-Infertile kunye neVogtelectronicComponentsGmbH.
I-parallel gear circuit yongezwa kwibhetri nganye yeqela lebhetri ye-lithium ion ukufezekisa injongo yokuhambisa. Kule modi, xa ibhetri ihlawulwe ngokupheleleyo, isixhobo sokulinganisa sinokuyithintela ekugqithiseni kwaye siguqule amandla angaphezulu kubushushu, kwaye siqhubeke nokutshaja ibhetri enganelanga. Le ndlela ilula, kodwa iya kubangela ukulahlekelwa kwamandla, ayifanelekanga inkqubo yokutshaja ngokukhawuleza.
Phambi kokutshaja, ibhetri nganye ikhutshelwa kwinqanaba elifanayo ngomthwalo ofanayo, ize ke iphinde itshaje ngokuqhubekayo ukuqinisekisa ukuba ibhalansi phakathi kweebhetri ichaneke ngakumbi. Nangona kunjalo, malunga neepakethi zebhetri, ngenxa yeyantlukwano ngokwasemzimbeni phakathi kwabantu, kunzima ukufikelela kanye isiphumo esifanelekileyo esingaguqukiyo emva kobunzulu beyunithi yebhetri nganye. Nangona umphumo ofanayo ufikeleleke emva kokukhutshwa, ukungalingani okutsha kwenzeka ngexesha lokutshaja.
