Isingeniso:
Amabhethri e-Lithium akuyo yonke indawo ezimpilweni zethu. Amabhethri ethu weselula namabhethri ezimoto zikagesi konkeamabhethri e-lithium, kepha uyayazi yini imigomo yebhethri eyisisekelo, izinhlobo zebhethri, neqhaza nomehluko wochungechunge lwebhethri nokuxhumana okufanayo? Ake sihlole ulwazi lwamabhethri ane-heltec.
Isizinda esiyisisekelo samabhethri e-lithium
1) I-C-Rate
Kubhekiswa isilinganiso esisesilinganisweni samanje kumthamo webhethri le-lithium ngesikhathi sokushaja nokukhipha. Ichaza ukuthi ibhethri lingakhokhiswa ngokushesha kangakanani futhi likhishwe. Ukushaja kanye namazinga okukhipha ama-diskarging awafani. Ngokwesibonelo:
I-1C: khipha ibhethri ngokuphelele kungakapheli ihora eli-1 (ukushaja okugcwele)
I-0.2C: khipha ibhethri ngokuphelele kungakapheli amahora ama-5 (ukushaja okugcwele)
I-5C: khipha ibhethri ngokuphelele ngaphakathi kwamahora ayi-0,2 (ukushaja okugcwele)
2) umthamo
Inani likagesi eligcinwe kuibhethri le-lithium. Iyunithi linguMah noma ah.
Kuhlanganiswe nesilinganiso, ngokwesibonelo, uma ibhethri lingu-4800mah kanye nezinga lokushaja kungu-0.2C, kusho ukuthi kuthatha amahora angama-5 ukuze ibhethri likhokhiswe ngokugcwele kusuka kungenalutho (ukunganaki isigaba sangaphambi kokushaja lapho ibhethri liphansi kakhulu).
I-Charging Yamanje yile: 4800mA * 0.2C = 0.96a
3) Uhlelo lokuphathwa kwebhethri lwe-BMS
Uhlelo lulawula futhi luphathe ukushaja / ukuhambisa ibhethri, kuthola amazinga okushisa kanye namavoloji webhethri, ukuxhuma nohlelo lokusingathwa, ukulinganisa i-volitrage yebhethri, futhi kulawula ukusebenza kwebhethri lebhethri le-lithium yebhethri.
4) Umjikelezo
Inqubo yokushaja kwebhethri nokukhishwa kwe-diskarging ibizwa ngokuthi umjikelezo. Uma ibhethri lisebenzisa ama-80% kuphela amandla ayo aphelele isikhathi ngasinye, impilo yomjikelezo yamabhethri e-lithium-ion angaba phezulu njengezinkulungwane zamahlandla.
Uhlobo lwebhethri lwe-Lithium
Njengamanje, amaseli we-lithium-ion angu-cylindrical, skwele kanye nepakethe elithambile.
Amaseli we-cylindrical ama-cylindrical amaseli we-lithium-ion anevolumu yokukhiqiza ephezulu njengamanje. Amaseli webhethri we-G Uchungechunge lwe-G alolo hlobo.
Uchungechunge lwe-Cell kanye nokuxhumana okufanayo
Iseli yingxenye esemqoka yeibhethri le-lithium. Inani lamaseli liyahlukahluka ngokuya ngokusetshenziswa kwebhethri, kepha wonke amabhethri adinga ukuxhunywa ngezindlela ezihlukile zokufeza i-voltage edingekayo.
Qaphela: Izimo zokuxhumana okuhambisanayo zinokhahlo kakhulu. Ngakho-ke, ukuxhumana okuhambisanayo kuqala bese uchungechungechungechungechunge lwe-Series lunganciphisa izidingo zokuvumelana kwebhethri.
Q: Uyini umehluko phakathi kochungechunge oluntathu kanye nokufana okune-ezine kanye namabhethri afanayo amane namanye ama-Series?
A: Amandla kagesi futhi umthamo wehlukile.Ukuxhumana kochungechunge kukhulisa i-voltage, futhi ukuxhumana okuhambisanayo kwandisa amanje (umthamo)
1) ukuxhumana okuhambisanayo
Thatha ukuthi i-voltage yeseli yebhethri ingu-3.7V futhi umthamo u-2.4h. Ngemuva kokuxhumeka okufanayo, i-voltage ye-terminal yohlelo ise-3.7V, kepha amandla akhuphuka aye ku-7.2h.
2) uchungechunge
Thatha ukuthi i-voltage yeseli yebhethri ingu-3.7V futhi umthamo u-2.4h. Ngemuva kokuxhuma uchungechunge, i-voltage ye-terminal yohlelo ingu-11.1V, futhi amandla ahlala engashintshiwe.
Uma iseli lebhethri lichungechunge amathathu kanye nokufana okubili, amaseli angama-6 18650, ibhethri lingu-11.1v no-4.88. I-Tesla Model-S Sedan isebenzisa amaseli wePanasonic 18650, kanye ne-85KKH yebhethri yebhethri idinga amaseli acishe abe ngu-7,000.
Ukugcina
IHeltec izoqhubeka nokuvuselela ulwazi oludumile lwesayensi mayelanaamabhethri e-lithium. Uma unentshisekelo, ungasinaka. Ngasikhathi sinye, sikunikeza ngekhwalithi ephezulu ye-Lithium Battery Packs yakho ukuze uthenge futhi unikeze ngezinsizakalo ezenziwe ngezifiso ukufeza izidingo zakho.
IHeltec Energy ngumlingani wakho othembekile ekukhiqizweni kwebhethri yebhethri. Ngokugxila kwethu ngokungapheli kokucwaninga nasekuthuthukisweni, okuhambisana nobubanzi bethu obubanzi bezesekeli zebhethri, Sinikeza izixazululo zokumisa eyodwa ukuze uhlangabezane nezidingo zalo mbombo. Ukuzibophezela kwethu ekusebenzeni kahle, izixazululo ezihambisana nakho, kanye nokubambisana kwamakhasimende okuqinile kusenza sikwazi ukukhetha abakhiqizi bebhethri bebhethri nabaphakeli emhlabeni jikelele.
Uma unemibuzo noma ungathanda ukufunda okuningi, sicela ungangabazifinyelela kithi.
