Yini i-C-rate yebhethri?

I-C-Rate yebhethri yiyunithi elinganisa ijubane lokushaja kwebhethri noma ukudilizwa, okwaziwa nangokuthi isilinganiso sokushaja / sokukhuphuka. Ngokukhethekile, isilinganiso se-C-simele ubudlelwano obuningi phakathi kokukhokhiswa kwebhethri / ukukhipha kwamanje kanye namandla alo alinganiselwe. Ifomula yokubala yile:

Ukushaja / Ukukhishwa Kwezinga = ukushaja / ukukhipha umthamo wamanje / olinganiselwe

Ukuchazwa nokuqonda kwe-C-rate

• Incazelo: I-C-Rate, okubizwa nangokuthi njengezinga lokushaja / ukukhishwa, isilinganiso secala lokushaja / ukukhipha kwamanje esikhundleni sebhethri. Isibonelo, ngebhethri elinekhono elilinganiselwe le-100AH, ukuhambisa endaweni yamanje ye-20a kufana nezinga lokukhipha le-0.2c.

• Ukuqonda: Izinga le-C-C-rate, njenge-1C, 2c, noma i-0.2c, libonisa ijubane lokukhipha. Izinga le-1C lisho ibhethri lingakhipha ngokugcwele ngehora elilodwa, kanti u-0.2c akhombisa ukukhipha amahora angaphezu kwamahlanu. Ngokuvamile, imisinga ehlukene yokuphuma ingasetshenziswa ukukala umthamo webhethri. Ibhethri le-24AH, ukukhipha i-2c kwamanje kungu-48a, kanti ukuphuma kwe-0.5c kwamanje kungu-12a.

Izicelo ze-C-Rate

• Ukuhlolwa kokusebenza: Ngokukhipha kumanani e-C ahlukene, kungenzeka ukuthi ahlole amapharamitha webhethri afana nomthamo, ukumelana kwangaphakathi, neplatifomu ye-desepus, okusiza ekuhloleni ikhwalithi yebhethri kanye nokuphila.

• Izimo Zokusebenza: Izimo ezihlukile zohlelo lokusebenza zinezidingo ezahlukahlukene ze-C-rate. Isibonelo, izimoto zikagesi zidinga amabhethri aphezulu we-C-rate ukuze akhokhelwe ngokushesha / ukukhipha, kuyilapho amasistimu wokugcina amandla ebeka phambili isikhathi eside nokubi, kuvame ukunikeza ukushaja okuphansi kwe-C-Rate kanye nokukhipha.

Izici ezithinta ama-C-rate

Ukusebenza kweseli

• Umthamo weseli Ngakho-ke, umthamo weseli unquma ngqo isilinganiso se-C. Okukhudlwana umthamo weseli, kwehlise amanani we-C ukuze kukhishwe okufanayo kwamanje, okuphambene nalokho.

• Izinto zeseli kanye nesakhiwo Ezinye izinto zokwakha zingasekela ukushaja okuphezulu kakhulu futhi zihambisane, kanti ezinye zingahle zilungele izinhlelo zokusebenza eziphansi.

I-Battery Pack Design

• Ukuphathwa kwe-Thermal: Ngesikhathi sokushaja / ukuphuma, iphakethe lebhethri lakha ukushisa okubalulekile. Uma ukuphathwa kwe-Thermal kunganele, amazinga okushisa angaphakathi azokhuphuka, akhawulele amandla okukhokhisa futhi aholele amanani e-C. Ngakho-ke, ukuklanywa okuhle okushisayo kubalulekile ukuthuthukisa inani lebhethri lebhethri.

• Uhlelo lokuqapha ibhethri (BMS) : Abaqaphi be-BMS futhi baphathe ibhethri, kufaka phakathi ukulawula imali / ukukhishwa, ukukhishwa, njll ngokulawula ngokunembile kwamandla okukhokhiswa kwebhethri, ngaleyo ndlela kuthuthukise amanani ebhethri.

Izimo Zangaphandle

• Ukushisa kwe-Ambient: Ukushisa kwezemvelo kuyinto ebalulekile ekusebenzeni kwebhethri. Emazingeni okushisa aphansi, ijubane lokushaja liyambulala, futhi umthamo wokukhipha uvinjelwe, wehlisa inani le-C. Ngakolunye uhlangothi, emazingeni okushisa aphezulu, ukushushuluza ngokweqile kungathinta ne-C-rate.

• Isimo sebhethri noma isimo sebhethri): Lapho i-bethy yebhethri iphansi, ukushaja kuvame ukuba ngokushesha, njengoba ukumelana kwangaphakathi kwamakhemikhali okusabela kwamakhemikhali kuphansi. Kodwa-ke, njengoba kusondela ngokugcwele, ijubane lokushaja kancane kancane liyancipha ngenxa yesidingo sokulawulwa okuqondile ukuze ugweme ukwedlula imali.

Ukubeka kafushane

I-C-Rate ibalulekile ekuqondeni ukusebenza kwebhethri ngaphansi kwezimo ezihlukile. Amanani we-C aphansi (isib. 0.1C noma u-0.2c) ajwayele ukusetshenziselwa izivivinyo zokushaja isikhathi eside / ukucubungula amandla okuhlola amandla, ukusebenza kahle, kanye nesikhathi sokuphila. Amanani e-C aphezulu (isib. I-1C, 2c, noma ngaphezulu) Hlola ukusebenza kwebhethri ukuze uthole izindleko zokushaja / zokukhipha, njengokushesha kwezimoto kagesi noma ukundiza kwemoto.

Kubalulekile ukuqaphela ukuthi i-C-rate ephakeme ayihlali ingcono. Ngenkathi ama-C-Rates aphezulu enika amandla ukushaja okusheshayo / ukuphuma, abuye alethe amathuba angaba khona anjengokusebenza okuncishisiwe, ukushisa kwempilo, kanye nempilo yebhethri emfushane. Ngakho-ke, lapho ukhetha futhi usebenzisa amabhethri, ukulinganisa isilinganiso se-C namanye amapharamitha okusebenza ngokuya ngohlelo lokusebenza nezidingo ezithile zibalulekile.
