Iipakethi zebhetri zeLithium zinjengeenjini ezingenalondolozo; aBmsNgaphandle komsebenzi wokulinganisa ngumqokeleli wedatha kwaye awunakuthathelwa ingqalelo inkqubo yolawulo. Zombini u-bala wokulinganisa osebenzayo kunye nokuhambisana nokushenxisa ukungangqinelani kwipakethi yebhetri, kodwa imigaqo-nkqubo yawo yokuphumeza ixhaswa.
Ukucaca, eli nqaku lichaza ukungcungcuthekiswa yi-BMS nge-algorithms njengokulinganisa okusebenzayo, ngelixa kulungelelanisa ukuba ukusebenzisa amandla okuhlela amandla. Ukulinganisa okusebenzayo kubandakanya ukudluliselwa kwamandla, kanti uBalali oBalani ubandakanya ukwahlukana kwamandla.
Imigaqo yoYilo lwebhetri yebhetri
- Ukutshaja kufuneka uyeke xa iseti yokuqala ihlawulisiwe ngokupheleleyo.
- Ukukhutshwa kufuneka kuphele xa iphelile iseli yokuqala.
- Ubuninzi be-CELS Iminyaka isantya kwiiseli ezinamandla.
- -iseli kunye nentlawulo ebuthathaka iya kuthi ekugqibeleni inciphise ipakethe yebhetri'Isikhundla esisebenzayo (ikhonkco elibuthathaka).
- Inkqubo yeqondo lobushushu le-Gradient kwipakethi yebhetri iyenza ukuba iiseli ezisebenza kwiqondo lokuhlala eliphezulu eliphezulu.
- Ngaphandle kokulinganisa, umahluko wevolthi phakathi kweseli ebuthathaka kwaye ezomeleleyo inyuka ngetyala ngalinye kunye nomjikelo wokukhululwa. Ekugqibeleni, iseli enye iza kufika kwi-voltage ephezulu ngelixa enye iyonke iyonke i-voltage, inyanzelise intlawulo yepakethi kunye nezakhono zokuphelisa.
Ngenxa yokunyibilika kweeseli ngokuhamba kwexesha kunye neemeko zobushushu ezivela kufakelo, ukulungelelaniswa kweseli kubalulekile.
Ibhetri ye-lithium-ion ngokuyintloko ijongene neentlobo ezimbini ze-mismatch: biza ukungasebenzi kakuhle kunye ne-mismatch yamandla. Ukutshaja kwe-mismatch kwenzeka xa iiseli zezahlulo ezifanayo ziye zahlukile. Imorimment yamandla yenzeka xa iiseli ezinezizathu ezahlukeneyo zokuqala zisetyenziswa kunye. Nangona iiseli zihlala zithambekele kakuhle ukuba ziveliswa malunga nexesha elifanayo neenkqubo zokwenza imveliso, i-mismatches zinokuvela kwiiseli ezinemahluko ongaziwayo okanye imithombo ebalulekileyo yokwenza umthombo ongaziwayo okanye umohluko okhethekileyo obonakalayo.
Ukulinganisa okusebenzayo vs
1. Injongo
Iipakethi zebhetri ziqukethe iiseli ezininzi ezixhunyiweyo, ezingalindelekanga ukuba zifane. Ukulinganisa kuqinisekisa ukuba ukuphambuka kweeseli ze-violtage kugcinwa ngaphakathi kwenqanaba elilindelekileyo, ukugcina ulungelelene ngokupheleleyo kunye nokulawulwa, ngaloo ndlela kuthintela ukonakala kwaye bandise ubomi bebhetri.
I-2. Ulolo Qhagamshela
- Ukulinganisa okungenayo: Ngokwesiqhelo kuphelisa iiseli eziphakamileyo ze-voltage usebenzisa abaqeqesheni, ukuguqula amandla amakhulu kubushushu. Le ndlela yandisa ixesha lokutshaya kwezinye iiseli kodwa inempumelelo ephantsi.
- Ukulinganisa okusebenzayo: Indlela enobunzima ephinda ihlawulwe ngaphakathi kweeseli ngexesha elihlawulwayo kunye nokunciphisa ixesha lokurhoxa, ukunciphisa ixesha lokutshaja kunye nokwandisa ixesha lokukhupha. Ngokuqhelekileyo kusebenzisa iindlela zokulinganisa ezingezantsi ngexesha lokukhupha kunye nezicwangciso-qhinga eziphezulu zokulinganisa ngexesha lokutshaja.
- Pros kunye nokuQaphela: Ukulinganisa okungenayo kulula kwaye isebenza kakubi kodwa isebenza kakuhle, njengoko inamandla njengobushushu kwaye ineziphumo zokulinganisa kancinci. Ukulinganisa okusebenzayo kusebenza ngakumbi, ukuhambisa amandla phakathi kweeseli, eziphucula ukusebenza kakuhle kokusetyenziswa ngokubanzi kwaye kufezekise ibhalansi ngokukhawuleza. Nangona kunjalo, kubandakanya izakhiwo ezintsonkothileyo kunye neendleko eziphezulu, kunye nemiceli mngeni ekuhlanganiseni ezi nkqubo kwii-ICC ezizinikeleyo.
Ukuqukumbela
Umxholo we-BMS ekuqaleni waphuhliswa kwelinye ilizwe, kunye noyilo lwe-IC olujongileyo kugxile kwi-voltage kunye nokufunyanwa kwamaqondo. Umxholo wokulinganisa wangeniswa kamva, ekuqaleni usebenzisa iindlela zokuthintela ukukhululwa okudityaniswe kwi-iC. Le ndlela ixhaphake kakhulu, neenkampani ezinje nge-ti, iMaxim, kwaye ilayinile i-chips, ezinye zidibanisa abaqhubi bee-swip.
Ukusuka kwimigaqo yokulinganisa ingenamkhethe kunye nemizobo, ukuba ipakethi yebhetri ithelekiswa negreyini, iiseli zinjengezibonda. Iiseli ezinamandla aphezulu ziiplanga ezinde, kwaye abo banamandla asezantsi ziiplanga ezimfutshane. Ukulungelelanisa kuphela "kuphela" ezifutshane "iiplinks ezinde, ezikhokelela ekuchitheni amandla kunye nokungasebenzi kakuhle. Le ndlela inomda, kubandakanya ukubekwa kobushushu obunobushushu kunye neziphumo zokulinganisa kancinci kwiipakethe ezinkulu.
Ukugcwalisa ngokusebenzayo, ngokwahlukileyo, "kuzalisa iiplanga ezimfutshane," ukuhambisa amandla kwiiseli ezinamaxabiso aphezulu ukuya kwi-on engaphantsi, okukhokelela ekusebenziseni okuphezulu kunye nokufumana ibhalansi ephezulu. Nangona kunjalo, yazisa imiba enobunzima kunye neendleko, ngemiceli mngeni ekutshintsheni imatriki yokuthumela kunye nokulawula.
Ngenxa yendawo yorhwebo, u-balation ongenantlonelo unokulungela iiseli ngokungqinelana okuhle, ngelixa ulali ngokusebenza okhethiweyo okhethekileyo kwiiseli ngamandla amakhulu.
