Isikhokelo soMthengi weBattery yeSithuthi esiSebenzayo
Ndibukele umphathi wezithuthi eRiyadh elahla i-$180,000 yeebhetri zeasidi ezixabisa i-$180,000{2}emva kweenyanga ezili-14. Ukugcinwa okubandayo, iishifti ezintathu, akukwazanga ukubamba intlawulo ngaphantsi kwe-15 degree. I-Sulfation yayidla ngokusebenzisa iipleyiti. Ngenyanga ye-11 iifolokhwe zakhe zaziqhwalela kwisiqingatha-sezitshifu.
Bekungo 2019. Ndikhe ndamnceda utyando lwakhe luqhuba i-LFP ukusukela ngoko. Unyaka wesihlanu ngoku, i-87% yokugcina umthamo kwiipakethi zokuqala.
Ingxaki yePhepha eliKhethekileyo
Uninzi lweziphoso zokuthenga ndizibona zihla ekuleqeni amanani angeyiyo. Wonke umntu ulungisa i-$/kWh xa ethenga. Yiloo nto mhlawumbi i-35% yento oza kuyisebenzisa ngokwenene.
Ndiza kufika kwi-TCO yokuqhekeka kamva, kodwa kuqala: ukuhambelana kweeseli. Lo ngumgangatho oguquguqukayo ongazange ubonakale kuncwadi lwentengiso, kwaye kulapho ababoneleli besika iikona xa befuna ukubetha indawo yexabiso.
Xa siphicotha ababoneleli, ukunyamezela ukuthelekisa iiseli ngumbuzo wam wokuqala. Abavelisi benqanaba lokuqala - bahambelana nomthamo ±2.5% kunye nokuxhathisa okufanayo kwangaphakathi. Kutheni ukuxhathisa kwangaphakathi kubaluleke ngaphezu komthamo wezicelo eziphezulu{4} zangoku? Kuba xa uneeseli ezinxuseneyo ezinoxhathiso olungahambelaniyo, okwangoku akusahluli ngokulinganayo. Esezantsi -iseli yokuxhathisa ithatha umthwalo omninzi, ishushu ngokukhawuleza, iguge ngokukhawuleza, kwaye ekugqibeleni irhuqa yonke ipakethe phantsi. I-MIT ibhalwe ukuba i-20% yokuchasana nokungahambi kakuhle kokunciphisa ubomi bomjikelo malunga ne-40% kumazinga aphezulu okukhutshwa (sciencedirect.com).
Yiminyaka yobomi benkonzo enyamalalayo ngenxa yokuba umntu ugcine i-3 yeedola kwiseli nganye ekufaniseni.
Inkqubo yokuhlela iyenza ibe mandundu. Emva kokutshaja, iiseli zilungelelaniswa ngokweBanga A, B, C, D. IBanga A licacisiwe-liyahambelana noko liphuma emgceni. IBanga B lidla ngokuhlala kwiBanga A elalihlala kwindawo yokugcina iimpahla iinyanga ezintathu ukuya kwezintandathu. Iimpawu ezifanayo ephepheni. Ukusebenza kwintsimi eyahlukileyo.
Omnye umthengisi waseShenzhen esamphicotha wayedibanisa i-15% yeeseli zeBanga B. Umthamo ofanayo kwi-database yabo. Iipakethi zabo zazisilela kwi-30% ngokukhawuleza kunabakhuphisana nabo kwinqanaba lexabiso elifanayo. Xa ndibuza malunga nokunyamezelana kwabo, i-rep rep ayikwazanga ukundinika inombolo. Oko kwandixelela yonke into.
Ixesha lokuqulunqa libalulekile, kwaye phantse akukho mntu ubuza ngayo. Ukuqulunqwa okufanelekileyo kufuna intlawulo epheleleyo{1}}umjikelo wokukhupha kunye nobuncinane beentsuku ezili-15 zokuphumla ukuze kubonakale iziphene ezifihlakeleyo. Ababoneleli phantsi koxinzelelo lwe-margin bacinezela oku. Iiseli zihamba kakuhle. Iziphene zivela kwinyanga yesi-8 xa udlule{7}}kwinqanaba lokukhomba.
BMS
Khawuleza apha kuba wonke umntu uyayenza nzima le nto.
Umzi-mveliso-ulungelelwaniso lomgangatho: Ngaphantsi okanye ilingana no-0.5% kwimvakalelo yangoku. Iimoto: Ngaphantsi okanye ilingana ne-1%. Umthengi: ngubani owaziyo.
Imeko-yo{1}}yoqikelelo lwentlawulo ludibanisa langoku ekuhambeni kwexesha. Ukuba indlela oziva ngayo ngoku ikhukuliseka nge-2%, unokuvala kwangoko okanye ngaphezulu{4}}uyakhupha. Ayibonakali kuvavanyo lokwamkelwa. Zombini zibulala ixesha lakho elingaphezulu kweenyanga ezili-18-24.
Ukulinganisa: inkunkuma engenziyo i-5-10% njengobushushu, ixabisa ngaphantsi. Ukudluliselwa kwamandla okusebenzayo phakathi kweeseli kwi-95% + ukusebenza kakuhle, yongeza i-$ 15-30 nge-kWh. Uninzi lwababoneleli ngenqanawa luyasebenza kuba abathengi abazi ukuba babuze ukuba bayasebenza. Ukuba usebenzisa ithuba lokutshaja, ukulinganisa okusebenzayo kuhlawula emva kweminyaka emibini.
Yiyo leyo. Qhubeka.
Ubushushu
Ndiphulukene nenani le-lithium "engaphumeleli" endiyiphandileyo eyajika yaba ziingxaki zolawulo lobushushu.
Ngaphantsi kwe-0 degree, musa ukubiza i-lithium. Ixesha. Ufumana i-lithium metal plating kwi-anode endaweni yokudibanisa okufanelekileyo. Umonakalo ongenakulungiseka. Umngcipheko womlilo ukusuka ekubunjweni kwe-dendrite. Nakuphi na ukugcinwa okubandayo okanye ukusasazwa kwangaphandle kwasebusika kufuna ukufudumeza okudibeneyo kunye nokuvalwa kwentlawulo ye-BMS. Andikhathali nokuba lithini iphepha lomboneleli wakho malunga noluhlu lokusebenza. Ukuba abakwazi ukucacisa{8}}ukhuseleko lwabo lobushushu obuphantsi ngokweenkcukacha, hamba.
Ilothe -iasidi ineengxaki ezibandayo ezahlukeneyo. Ngaphantsi kwe-15℃, iiseli ezikhukulayo azikwazi kwamkela intlawulo epheleleyo. Ubaleka kwi-60-70% umthamo ngelixa unyusa i-sulfation. Omnye umphathi weenqanawa waseKhanada endimaziyo wayechitha i-8,000 yeedola ngonyaka kumagumbi ebhetri ashushu. Akazange abonakale kwimodeli yakhe ye-TCO yangaphambili kuba akukho mntu wabuza malunga nobushushu obuphakathi ngexesha lokuthengisa.
Isiphelo esiphezulu: I-LFP ibamba ukuya kuthi ga kwi-60℃ngaphambi kokuba izinto zibe mbi. I-NMC iqinile, mhlawumbi i-55 degree. Umahluko wepakethi yobushushu kufuneka uhlale ngaphantsi kwe-5 degree. Ukupholisa ulwelo kwenza oku kodwa kongeza iindleko kunye nokugcinwa. Ukupholisa komoya kusebenza ukuba ungaphantsi kwe-2C ngokuqhubekayo kwaye i-ambient ihlala ingaphantsi kwe-35 degree.
Ngokwenyani, nantsi into ekufuneka ndiyikhankanye ngelixa sikwiqondo lobushushu. Uluhlu olusebenzayo lweshiti luthetha ukuba iiseli aziyi kusilela ngoko nangoko. Ayithethi ukusebenza kakuhle. Ipakethi elinganiselwe kwi-20 ukuya kwi-60℃iya kuguga ngokukhawuleza kwizinto ezigqithisileyo. Sasinomthengi ePhoenix oqhuba ii-AGV zangaphandle ezingakwaziyo ukuqonda ukuba kutheni iipakethi zabo zifa kwi-60% yobomi bomjikelo olinganisiweyo. Zajika izixhobo zabo zihleli elangeni ngqo ngexesha lekhefu lesidlo sasemini, bebetha i-50℃+ rhoqo. Ngokobuchwephesha ngaphakathi spec. Ngokuqhelekileyo ukubulala iiseli.
TCO
Kulungile, amanani. Nditsale oku kwiprojekthi yaseTexas 3PL esiyenzileyo 2024. 50 kudidi I forklifts, ezimbini-ishedyuli yeshift, uhlalutyo lweminyaka esi-8:
