Ubani Umhlinzeki Ongcono Kakhulu Wezixazululo Zebhethri Le-Lithium?
Bengifuna amabhethri ezimbonini ukuze ngithole okokusebenza okuphathekayo kusukela ngo-2018. Ukuguqulwa okuthathu kwendawo yokugcina impahla, ukubuyisela kabusha okubili kwesitoreji esibandayo, iphrojekthi eyodwa ye-GSE yesikhumulo sezindiza. Yonke iphrojekthi iqale ngombuzo ofanayo okuletha lapha.
Akekho umhlinzeki oyedwa "ongcono kakhulu". Kodwa kukhona abahlinzeki abazocekela phansi ukusebenza kwakho, kanye nabahlinzeki abazoletha lokho abakuthembisayo. Umehluko wehlela ezintweni iningi lamashidi okuqhathanisa e-RFQ aphuthelwa ngokuphelele.
Inkinga Akekho Okhuluma Ngayo Ezincwadini Zabahlinzeki
Ngonyaka odlule ngasiza isikhungo sokusabalalisa eMidwest ukuthi sihlole izinga lokuhluleka kwebhethri laso. Babeshintshele ku-lithium ezinyangeni eziyi-18 ngaphambili, bathenge kumphakeli onikeza amanani angama-35% ngaphansi kwesilinganiso semakethe. Izinga lokuthengisa lalihlanganisa "iBanga{4}}amaseli e-CATL" kanye "newaranti yeminyaka emi-5."
Lapho sivula amaphekhi ahlulekile, amakhodi e-QR kumaseli ayeklwetshiwe. Amaseli ebanga A{1}angempela avela kubakhiqizi abafana ne-CATL, BYD, noma i-EVE Energy anamakhodi alandelekayo axhumeka emuva kudatha yenqwaba yokukhiqiza. Uma lawo makhodi ekhishwa, kusho ukuthi othile akafuni ukuthi wazi izinga leqiniso leseli. Sithumele amasampuli kulebhu-yenkampani yangaphandle. Amaseli abesezingeni B-kakuhle kakhulu, nokuhluka komthamo okudlula u-8% uma kuqhathaniswa -nezinga lebanga elingu-±2.5%.
Lokhu akuhlukanisiwe. Esithangamini se-Endless Sphere DIY, umsebenzisi oyedwa ubike ukuthi uthenga ibhethri elingu-48V 72Ah elingakwazi ukuletha umthamo wangempela ongu-10Ah. Omunye uphawule ukuthi umphakeli uvumile ukuthi bakhulisa izilinganiso zamandla ukuze bawine ukuthengisa (endless-sphere.com/sphere/threads/beware{{7}of-i-ebike-inkohliso{10}}nomthamo{11}}kanye{12}}namaseli{13}2}285. Iforamu yochwepheshe ye-ForkliftAction ixoxa izindaba ezifanayo: ochwepheshe bathola amabhethri e-lithium ahluleka kahle ngaphambi kokukalwa komjikelezo wempilo, cishe njalo alandelelwa emuva kukhwalithi yeseli, ukucushwa kwe-BMS, noma izinqamuleli zokuphatha okushisayo.
Okubalulekile Ngempela Lapho Uhlola Abahlinzeki
Ukuthola amaseli nokubeka izinto ngale
Amaseli e-Premium LiFePO4 adlula kunqubo yokugreda ngemva kokukhiqiza. Isiteji sokugqoka i-electrode sidinga ukubekezelela ukushuba ngaphansi kwe-2μm.
