Ukuqaliswa kokulinganisa okusebenzayo kunye nokulinganisa okusebenzayo kwebhodi yokukhusela ibhetri ye-Li-ion
1.Ukulinganisa okwenziwayo
Ukulinganisa okungahambiyo ngokuqhelekileyo kukhupha ibhetri ephezulu yombane we-lithium-ion ngokukhutshelwa okuchasayo, ukukhupha amandla ngendlela yobushushu ukuze kuthengwe ixesha elingakumbi lokutshaja kwezinye iibhetri. Ngale ndlela amandla enkqubo yonke anqunyelwe yibhetri enomthamo omncinci. Ngexesha lokutshaja, iibhetri ze-lithium-ion ngokubanzi zinexabiso lomda wokukhusela umbane, xa umtya weebhetri ufikelela kweli xabiso le-voltage, ibhodi yokukhusela ibhetri ye-lithium-ion iya kunqumla isiphaluka sokutshaja kwaye iyeke ukutshaja. Ukuba i-voltage yokutshaja idlula eli xabiso, eyaziwa ngokuba yi-overcharge, ibhetri ye-lithium-ion inokutshisa okanye iqhume. Ke ngoko, iiphaneli zokukhusela ibhetri ye-lithium-ion ngokubanzi zixhotyiswe ngokhuseleko lokutshajiswa kakhulu ukuthintela ibhetri ukuba ingahlawuliswa kakhulu.
Inzuzo yokulinganisa i-passive yindleko ephantsi kunye noyilo olulula lwesekethe; kunye nokungalunganga kukuba i-battery encinci ye-residual isetyenziswe njenge-benchmark yokulinganisa, ngoko akunakwenzeka ukunyusa umthamo webhetri kunye ne-residual engaphantsi, kwaye i-100% yamandla alinganayo ichithwa ngendlela yokushisa.
2. Ukulinganisa okusebenzayo
Ukulinganisa okusebenzayo kukulingana ngokugqithiswa kwamandla kunye nokusebenza kakuhle kunye nelahleko ephantsi. Indlela iyahluka ukusuka kumenzi ukuya kumenzi kunye nokulinganisa ngoku kuyahluka ukusuka kwi-1 ukuya kwi-10? A. Uninzi lwetekhnoloji yokulinganisa esebenzayo ekhoyo ngoku emarikeni ayikakhuli, nto leyo ekhokelela ekukhutshweni okugqithisileyo kunye nokukhawuleza ukubola kwebhetri. Uninzi lwe-equalization esebenzayo kwiimarike zisebenzisa umgaqo wombane oguquguqukayo, ngokuxhomekeke kwiitshiphu ezibizayo zabenzi beetshiphu. Kwaye ngale ndlela, ukongeza kwi-chip yokulinganisa, kodwa kunye neziguquli ezibizayo kunye nezinye iindawo ze-peripheral, ezinkulu kwaye zibiza kakhulu.
Izibonelelo zokulinganisa okusebenzayo ziyabonakala: ukusebenza okuphezulu, amandla adluliswa, ilahleko yilahleko ye-coil ye-transformer kuphela, ibalwa kwipesenti encinci; ukulinganisa okwangoku kunokuqulunqwa ukufikelela kwii-amps ezimbalwa okanye nakwizinga le-10A, umphumo wokulinganisa ukhawuleza. Ngaphandle kwezi zibonelelo, ukulingana okusebenzayo kuzisa iingxaki ezintsha. Okokuqala, isakhiwo sinzima, ngakumbi indlela ye-transformer. Indlela yokuyila i-matrix yokutshintshela amashumi okanye amakhulu eentambo zeebhetri, kunye nendlela yokulawula umqhubi, zonke iintloko. Ngoku ixabiso le-BMS elinomsebenzi wokulinganisa osebenzayo liya kuba liphezulu kakhulu kunokulinganisa kwe-passive, okukhawulelana nokukhuthazwa kwe-equalization esebenzayo i-BMS ngaphezulu okanye ngaphantsi.
I-equalization ye-Passive ifanelekile kwi-small-capacity, i-low-series ye-lithium-ion ye-bettery pack applications, ngelixa i-equalization esebenzayo ifanelekile kwi-high-series, i-high-capacity power-high-capacity power lithium-ion applications pack pack. Kwi-BMS, ngaphandle komsebenzi wokulinganisa kubaluleke kakhulu, iqhinga lokulinganisa ngasemva libaluleke kakhulu.
Ibhodi yokukhusela ibhetri yeLithium-ion umgaqo wokulinganisa
Iindlela zokutshaja ezisetyenziswa ngokuqhelekileyo zibandakanya ukutshaja kwe-shunt resistor equalization chargeging, on-off shunt resistor equalization chargeging, avareji yokulinganisa ukulinganisa umbane weseli ukutshaja, ukutshaja kwe-capacitor yokulinganisa ukulinganisa, ukutshaja kwe-buck converter ukulingana kokulinganisa, ukutshaja kwe-inductor yokulinganisa, njl. kumaqela, ibhetri nganye kufuneka iqinisekiswe ukuba ihlawuliswe ngokulinganayo, ngaphandle koko ukusebenza kunye nobomi bebhetri yonke iya kuchaphazeleka ngexesha lokusetyenziswa.
