Umgaqo wetekhnoloji yokukhupha i-pulseisixhobo sokulungisa ukulinganisa ibhetriIsekelwe kakhulu kwisignali ye-pulse ukuze yenze imisebenzi ethile yokukhupha ibhetri ukuze kufezekiswe imisebenzi yokulinganisa kunye nokulungisa ibhetri. Oku kulandelayo yintshayelelo eneenkcukacha kwitekhnoloji yokukhupha i-pulse yesixhobo sokulungisa i-equalization yebhetri:
Ukuveliswa kwesignali ye-pulse
Iisixhobo sokulungisa ukulinganisa ibhetriinomatshini ovelisa isignali ye-pulse ekhethekileyo ngaphakathi, odla ngokwenziwa yisekethe yokujikajika, isekethe yokulawula, njl. Isekethe yokujikajika inokuvelisa imiqondiso ye-pulse ene-frequency ephezulu okanye ephantsi, kwaye iiparameter ezifana ne-frequency, ububanzi kunye ne-amplitude yezi signals zinokulungiswa njengoko kufuneka. Isekethe yokulawula ilawula ngokuchanekileyo isignali ye-pulse eveliswa yisekethe yokujikajika ngokwemeko ethile yebhetri kunye nenkqubo emiselweyo ukuze ikhuphe ulandelelwano lwe-pulse oluhlangabezana neemfuno.
Inkqubo yokukhupha i-pulse
Uqhagamshelo nebhetri: Qhagamshela umlungisi wokulinganisela ibhetri kwiphakheji yebhetri ukuze icutshungulwe nge-interface ethile, kwaye isekethe yokukhupha i-pulse yomlungisi yenza iluphu evaliweyo kunye neseli yebhetri okanye iphakheji yebhetri.
Umgaqo wokukhupha umbane: Xa isignali ye-pulse ikwinqanaba eliphezulu, into yokutshintsha (efana ne-transistor yamandla, njl.njl.) kwisekethe yokukhupha umbane iyavulwa, kwaye ibhetri ikhupha itshaja kwisekethe yokukhupha umbane ukuze yenze umsinga wokukhupha umbane. Ngexesha lenqanaba eliphantsi lesignali ye-pulse, into yokutshintsha iyacinywa kwaye inkqubo yokukhupha umbane iyamiswa. Ngokuphinda le nkqubo yokukhupha umbane ephezulu kunye nenkqubo yokusika umbane ephantsi, kwenziwa i-pulse discharge.
Ukukhululwa nokudluliselwa kwamandla: Ngexesha lenkqubo yokukhupha i-pulse, amandla ekhemikhali ngaphakathi kwebhetri aguqulwa abe ngamandla ombane aze akhutshwe ngesekethe yokukhupha. Kwiseli nganye yebhetri kwiphakheji yebhetri, ukuba kukho ukungalingani kwe-voltage, iseli yebhetri ene-voltage ephezulu iya kukhupha itshaja engaphezulu ngexesha lenkqubo yokukhupha i-pulse, ngelixa iseli yebhetri ene-voltage ephantsi iya kukhupha itshaja encinci. Ngale ndlela, ngokulawula iiparameter ze-pulse kunye nexesha lokukhupha, njl.njl., itshaja yeseli nganye yebhetri inokuqhubeka ihambelana, ngaloo ndlela ifezekisa ukulinganisela kwebhetri.
Isiphumo kwibhetri
Ukususa i-polarization: Ibhetri iya kuvelisa i-polarization ngexesha lenkqubo yokutshaja nokukhupha i-charging, nto leyo ebangela ukwehla kokusebenza kwebhetri. Itekhnoloji yokukhupha i-pulse ingasebenzisa isiphumo esikhethekileyo semiqondiso ye-pulse ukuze isuse ngempumelelo i-concentration polarization kunye ne-electrochemical polarization yebhetri ngexesha lenkqubo yokukhupha i-pulse. Umzekelo, ngexesha elifutshane lokukhupha i-pulse, ukusasazwa kwe-ion concentration ngaphakathi kwebhetri kunokubuyiselwa kwinqanaba elithile, ngaloo ndlela kunciphisa impembelelo ye-polarization ekusebenzeni kokutshaja nokukhupha ibhetri, kunye nokuphucula ukusebenza kakuhle kokutshaja nokukhupha ibhetri kunye nokubuyisela umva.
Ukulungisa i-sulfation: Kwiintlobo zeebhetri ezifana neebhetri ze-lead-acid ezithambekele ekutsaleni i-sulfation, iteknoloji yokukhupha i-pulse inesiphumo esithile sokulungisa. Xa kuvela ii-sulfides kwiiplate zebhetri, ukukhupha i-pulse nge-frequency efanelekileyo kunye ne-amplitude kunokuvelisa imisinga emikhulu ngoko nangoko ukuze ichaphazele ii-sulfides, nto leyo ebangela ukuba isakhiwo sekristale ye-sulfide sitshintshe, sibole kancinci size sinyibilike kwi-electrolyte, ngaloo ndlela sibuyisela izinto ezisebenzayo zeeplate zebhetri kwaye siphucule amandla ebhetri kunye nokusebenza kwayo.
Ibhetri elungeleleneyo: Kwibhetri, iiseli ezahlukeneyo zebhetri zinokuba nomahluko kumthamo, ukumelana kwangaphakathi, njl.njl. ngenxa yezizathu ezifana nenkqubo yemveliso kunye nendawo yokusetyenziswa, nto leyo ebangela ukungalingani ngexesha lenkqubo yokutshaja nokukhupha itshaja.isixhobo sokulungisa ukulinganisa ibhetriItekhnoloji yokukhupha i-pulse ilawula ukukhutshwa kweseli nganye yebhetri ukuya kumanqanaba ahlukeneyo, ivumela iiseli ezine-voltage ephezulu kunye nomthamo omkhulu ukuba zikhuphe umbane omninzi, ngelixa iiseli ezine-voltage ephantsi kunye nomthamo omncinci zikhupha umbane omncinci. Ekugqibeleni, ifezekisa ulungelelwaniso lweeparameter ezifana ne-voltage kunye namandla eseli nganye kwiphakheji yebhetri, ngaloo ndlela iphucula ukusebenza kunye nobomi benkonzo yephakheji yebhetri iyonke.
