I-C-rate yebhethri iyunithi ekala isivinini sokushaja noma ukushajwa kwebhethri, esaziwa nangokuthi izinga lokushaja/lokukhipha. Ngokukhethekile, isilinganiso se-C simele ubudlelwano obuningi phakathi kwamandla ebhethri/ukukhipha amandla kanye nomthamo walo olinganiselwe. Ifomula yokubala ithi:
Izinga lokushaja/lokukhipha = Inkokhelo/Yokukhipha Imali Yamanje / Isilinganiso Esilinganiselwe
Incazelo: Izinga le-C, elibuye libizwe ngezinga lokushaja/lokukhipha, isilinganiso samanje sokushajwa/sokukhipha kumthamo webhethri. Isibonelo, kubhethri elinomthamo olinganiselwe ongu-100Ah, ukushajwa ngesilinganiso samanje esingu-20A kuhambisana nezinga lokukhishwa elingu-0.2C.
Ukuqonda: I-C-rate yokukhipha, efana ne-1C, 2C, noma i-0.2C, ibonisa isivinini sokukhipha. Izinga elingu-1C lisho ukuthi ibhethri lingaphuma ngokugcwele ehoreni elilodwa, kanti u-0.2C ubonisa ukushajwa kwamahora amahlanu. Ngokuvamile, imisinga ehlukene yokukhipha amanzi ingasetshenziswa ukukala umthamo webhethri. Kubhethri elingu-24Ah, i-2C yokukhipha amandla yamanje ingu-48A, kuyilapho ukukhishwa okungu-0.5C kungu-12A.
Ukuhlolwa kokusebenza: Ngokukhipha ngamanani ahlukene e-C, kungenzeka ukuhlola amapharamitha ebhethri njengomthamo, ukumelana kwangaphakathi, nenkundla yokukhipha, esiza ukuhlola ikhwalithi yebhethri neminyaka yokuphila.
Izimo zohlelo lokusebenza: Izimo ezihlukene zohlelo lokusebenza zinezidingo ezihlukene zesilinganiso se-C. Isibonelo, izimoto zikagesi zidinga amabhethri anesilinganiso esingu-C esiphezulu ukuze ashaje/akhishwe ngokushesha, kuyilapho amasistimu okugcina amandla ebeka phambili ukuphila okude ne
Ukusebenza Kweseli
Umthamo Weseli: I-C-rate empeleni iyisilinganiso sokushaja/ukukhishwa kwamanje kumthamo olinganiselwe weseli. Ngakho, umthamo weseli unquma ngokuqondile izinga lika-C. Uma umthamo weseli umkhulu, izinga le-C liyancipha lamanje lokuphuma okufanayo, futhi okuphambene nalokho.
Impahla Yeseli Nesakhiwo: Izinto kanye nesakhiwo seseli, okuhlanganisa izinto ze-electrode, nohlobo lwe-electrolyte, kuthonya ukusebenza kokushaja/ukukhipha futhi ngaleyo ndlela kuthinte izinga le-C. Ezinye izinto zingase zisekele ukushaja nokushajwa kwezinga eliphezulu, kanti ezinye zingase zilungele izinhlelo zokusebenza ezinenani eliphansi.
I-Battery Pack Design
Ukuphatha Okushisayo: Ngesikhathi sokushaja/ukukhipha, iphakethe lebhethri likhiqiza ukushisa okukhulu. Uma ukuphathwa kwe-thermal kunganele, amazinga okushisa angaphakathi azokhuphuka, anciphise amandla eshaja futhi kube nomthelela ku-C-rate. Ngakho-ke, idizayini enhle yokushisa ibalulekile ekuthuthukiseni izinga lebhethri le-C.
Isistimu Yokuqapha Ibhethri (BMS) : I-BMS iqapha futhi iphathe ibhethri, okuhlanganisa ukulawula ukushajwa/ukuphuma, izinga lokushisa, njll. Ngokulawula ngokunembile ukushajwa/ukukhishwa kwamandla kanye nogesi, i-BMS ithuthukisa ukusebenza kwebhethri, ngaleyo ndlela ithuthukise izinga le-C.
Izimo zangaphandle
I-Ambient Temperature: Izinga lokushisa lendawo liyisici esibalulekile ekusebenzeni kwebhethri. Emazingeni okushisa aphansi, isivinini sokushaja siyahamba kancane, futhi umthamo wokukhipha uyakhawulelwa, kunciphisa izinga le-C. Ngokuphambene, emazingeni okushisa aphezulu, ukushisa ngokweqile kungase kuthinte izinga le-C.
Isimo Sokushaja Sebhethri (SOC): Uma i-SOC yebhethri iphansi, ukushaja kuvame ukushesha, njengoba ukumelana kwamakhemikhali kwangaphakathi kuphansi kakhulu. Kodwa-ke, njengoba isondela ekushajweni okugcwele, ijubane lokushaja liyancipha kancane kancane ngenxa yesidingo sokulawula okunembayo ukuze kugwenywe ukushaja ngokweqile.
I-C-rate ibalulekile ukuze uqonde ukusebenza kwebhethri ngaphansi kwezimo ezihlukene. Amazinga e-C aphansi (isb., 0.1C noma 0.2C) avame ukusetshenziselwa ukuhlola ukushaja/ukukhishwa kokukhishwa kwesikhathi eside ukuze kuhlolwe umthamo, ukusebenza kahle, neminyaka yokuphila. Amazinga aphezulu ka-C (isb., 1C, 2C, noma ngaphezulu) ahlola ukusebenza kwebhethri ngezidingo zokushaja okusheshayo/zokukhipha, njengokusheshisa imoto kagesi noma indiza ye-drone.
Kubalulekile ukuqaphela ukuthi izinga le-C eliphakeme alihlali lingcono ngaso sonke isikhathi. Nakuba amanani e-C aphezulu anika amandla ukushaja/ukukhipha okusheshayo, aphinda alethe ukwehla okungaba khona njengokuncipha kokusebenza kahle, ukukhushulwa kokushisa, nokuphila kwebhethri okufushane. Ngakho-ke, lapho ukhetha futhi usebenzisa amabhethri, ukulinganisa izinga le-C namanye amapharamitha okusebenza ngokuya ngohlelo lokusebenza oluthile kanye nezidingo kubalulekile.
