1.Ukulinganisa okwenziwayo

Ukulinganisa okungenzi lutho ngokuvamile kukhipha ibhethri ye-lithium-ion ephezulu kagesi ngokukhipha okuphikisayo, kukhulula amandla asesimweni sokushisa ukuze kuthengwe isikhathi sokushaja esengeziwe kwamanye amabhethri. Ngale ndlela amandla esistimu yonke anqunyelwe ibhethri elinomthamo omncane. Ngesikhathi sokushaja, amabhethri e-lithium-ion ngokuvamile anenani levolthi yokuvikela umkhawulo weshaji, lapho uchungechunge lwamabhethri lufinyelela leli nani lamandla kagesi, ibhodi lokuvikela ibhethri le-lithium-ion lizonqamula isekethe yokushaja futhi liyeke ukushaja. Uma i-voltage yokushaja idlula leli nani, elivame ukubizwa ngokuthi ukushajwa ngokweqile, ibhethri ye-lithium-ion ingase ishise noma iqhume. Ngakho-ke, amaphaneli okuvikela ibhethri ye-lithium-ion ngokuvamile ahlonywa ukuvikela ukushajwa ngokweqile ukuze kuvinjwe ibhethri ukuthi lishajwe ngokweqile.

Inzuzo ye-equalization yokwenziwa yizindleko eziphansi kanye nomklamo wesifunda olula; futhi okubi ukuthi ubuncane bensalela yebhethri busetshenziswa njengebhentshimakhi yokulinganisa, ngakho-ke akunakwenzeka ukwandisa umthamo webhethri ngensalela encane, futhi u-100% wamandla alinganayo achithwa ngendlela yokushisa.

2. Ukulinganisa okusebenzayo

Ukulinganisa okusebenzayo ukulinganisa ngokudluliswa kwamandla ngokusebenza kahle okuphezulu nokulahlekelwa okuphansi. Indlela iyahlukahluka kumkhiqizi kuye kumkhiqizi futhi izinga lokulinganisa liyahlukahluka ukusuka ku-1 kuye ku-10?A. Ubuchwepheshe obuningi bokulinganisa obusebenzayo obukhona manje emakethe abuvuthiwe, okuholela ekuchithekeni ngokweqile kanye nokubola kwebhethri ngokushesha. Iningi lokulinganisa okusebenzayo emakethe lisebenzisa isimiso se-voltage eguquguqukayo, sithembele kuma-chips abizayo abakhiqizi bama-chip. Futhi ngale ndlela, ngaphezu kwe-chip yokulinganisa, kodwa futhi ama-transformer abizayo nezinye izingxenye ze-peripheral, ezinkulu futhi ezibiza kakhulu.

Izinzuzo zokulinganisa okusebenzayo zisobala: ukusebenza kahle okuphezulu, amandla adluliswa, ukulahlekelwa kuphela ukulahlekelwa kwekhoyili ye-transformer, kubalwa ngamaphesenti amancane; i-equalization current ingaklanywa ukuthi ifinyelele ama-amps ambalwa noma izinga le-10A, umphumela wokulinganisa uyashesha. Naphezu kwalezi zinzuzo, ukulingana okusebenzayo nakho kuletha izinkinga ezintsha. Okokuqala, isakhiwo siyinkimbinkimbi, ikakhulukazi indlela ye-transformer. Indlela yokuklama i-matrix yokushintsha inqwaba noma ngisho namakhulu ezintambo zamabhethri, nendlela yokulawula umshayeli, konke kuyikhanda elibuhlungu. Manje intengo ye-BMS enomsebenzi wokulinganisa osebenzayo izoba phezulu kakhulu kunaleyo yokulinganisa okwenziwayo, okuphinde kukhawulele ukukhuthazwa kwe-BMS yokulinganisa okusebenzayo ngaphezulu noma ngaphansi.

Ukulinganisa okungenakwenziwa kulungele ukusetshenziswa kwebhethri ye-lithium-ion yamandla amancane, uchungechunge oluphansi, kuyilapho ukulinganisa okusebenzayo kulungele uchungechunge oluphezulu, izinhlelo zokusebenza zephakethe lebhethri le-lithium-ion lamandla aphezulu. Ku-BMS, ngaphandle komsebenzi wokulinganisa ubaluleke kakhulu, isu lokulinganisa ngemuva libaluleke kakhulu.

Umgomo wokulinganisa webhodi lokuvikela ibhethri le-lithium-ion

Izindlela zokushaja zokulinganisa ezivame ukusetshenziswa zifaka ukushaja kokulinganisa kwe-shunt resistor, ukushaja kokulinganisa kwe-shunt resistor ekucishiwe, ukushaja kwesilinganiso sokulinganisa amandla kagesi weseli, ukushaja kokulinganisa kwe-capacitor okushintshiwe, ukushaja kokulinganisa kwe-buck converter, ukushaja kokulinganisa kwe-inductor, njll. Uma ushaja amabhethri e-lithium-ion ochungechungeni ngamaqembu, ibhethri ngalinye kufanele liqinisekiswe ukuthi lishajwa ngokulinganayo, ngaphandle kwalokho ukusebenza nempilo yebhethri lonke kuzothinteka ngesikhathi sokusetshenziswa.
