Iyini Isitoreji Esibandayo?

Ngabuzwa lo mbuzo embukisweni wezohwebo ngonyaka odlule. Insizwa ephuma e-European ESS integrator ibifuna ukwazi ukuthi kungani umphakeli wayo ekhokhisa imali eyengeziwe "ngochungechunge olubandayo." Wayecabanga ukuthi umkhonyovu. Kwakungenjalo.

Amaseli e-lithium awonakala uma ehlezi eshalofini. Lapho i-warehouse ishisa kakhulu, ilahlekelwa amandla ngokushesha. Lokhu akuwona umphumela omncane. Ngibone idatha yokuhlola evela kumkhiqizi weseli ebonisa ukulahlekelwa kwamandla angu-2-3% ezinyangeni eziyisithupha ku-35℃uma kuqhathaniswa nengxenye yephesenti ku-20 degree. Amaseli ayengasetshenzisiwe. Uhlezi nje.

Isitoreji esibandayo siyile ndlela ezwakala ngayo. Ubeka amaseli endaweni enezinga lokushisa-elawulwayo, uyigcine endaweni ethile cishe ku-15-25℃, futhi ulawule umswakama. Ukusabela okuseceleni ngaphakathi kweseli kuhamba kancane. Isendlalelo se-SEI sikhula kancane. Ulahlekelwa i-lithium encane.

Ngemuva kwehlobo lika-2022, akekho e-China ophikisana ngokuthi isitoreji esibandayo sibalulekile yini. I-Eastern China ishaye amadigri angama-40 amasonto. Ngizwe ngothile kumenzi wephakethe we-Jiangsu ukuthi abahlinzeki bamaseli abambalwa kwadingeka babhale phansi i-inventory ngoba amaseli aphume endaweni yokubeka enomthamo ophansi ngokuphawulekayo kune-spec. Ukuthi leyo ndaba iyihaba, ngeke ngisho, kodwa isikhathi sihambisana nokuthi ukuthuthukiswa kwesitoreji esibandayo kwaqala nini ukubonakala ezinhlelweni zawo wonke umuntu.

Awukwazi ukuvele uphonse amaseli endaweni yokugcina ebandayo nganoma yisiphi isimo senkokhelo. Ukushaja okugcwele kubi ku-cathode. Isakhiwo se-oxide enengqimba ephezulu-ye-nickel NMC ayithandi ukuhlala ku-4.2V izinyanga. Okuthile mayelana nezinguquko zesigaba ezingenakuhlehliswa. Angiyena usosayensi wezinto ezisetshenziswayo, ngakho-ke ngeke ngenze sengathi ngiwuqonda ngokugcwele umshini, kodwa umphumela uwukulahlekelwa kwamandla okulinganiswa.

Amaseli angenalutho mabi kakhulu. Uma i-voltage yehla kakhulu, umqoqi wamanje wethusi uqala ukuncibilika. Ukhokhisa iseli ukuze libuyisele emuva bese ithusi lifaka endaweni lapho okungafanele khona. Ukuphikiswa kwangaphakathi kuyenyuka. Ngezinye izikhathi iseli livele lihluleke ngokuphelele.

Indawo emnandi iphakathi kuka-30% no-50% SOC. I-BYD ngokusobala idinga u-40% kanye noma khipha u-5% kumaseli e-Blade angena kwisitoreji. Angikayiboni idokhumenti yangempela kodwa abantu abaningi bayishilo le nombolo. I-LFP iyakhohlisa ngoba ijika le-voltage liyisicaba. Kunzima ukwazi kahle ukuthi ukuyiphi i-SOC kusuka ku-voltage yokulinganisa. Abanye abakhiqizi bashaja ngokugcwele{9}}umjikelezo wokukhipha ngaphambi kwesitoreji ukuze balinganise.

I-LFP iphatha amakhaza kangcono kune-ternary. I-Gotion ibala izinga lokushisa lesitoreji lehle liye ku-20℃negative kudatha yedatha yabo. -I-nickel NCA ephezulu kanye ne-NCM ziyakhethwa. Amaseli e-Samsung SDI NCA afuna i-15-25℃uma ngikhumbula i-spec efanele. Hamba ngaphansi kwe-10℃futhi i-electrolyte iba yi-viscous kakhulu. Kuthinta ikhwalithi yokwakheka ngokusobala.

I-SVOLT inezidingo eziqine nakakhulu kumaseli ayo amafushane-e-blade. Okuthile okungaba ngu-18-23℃nokubekezelela okungu-2 degrees noma iyiphi indlela. Akulula ukunakekela unyaka{11}}uzungeza eningizimu ye-China lapho izinga lokushisa langaphandle lasehlobo lifinyelela ku-40. Izicindezela zisebenza ngokungami. Izikweletu zikagesi ziba zimbi. Omunye osebenzisa indawo yokugcina impahla engikhulume naye uthe umthethosivivinywa wabo wamandla kaJulayi ungaphezu kuka-100,000 RMB futhi lokho kwathathwa njengokujwayelekile endaweni ephakathi nendawo.

Abanye abakhiqizi baphumuza buthule umkhawulo ongaphezulu ube ngamadigri angama-28 phakathi nehlobo eliphakeme kakhulu. Bese besebenzisa isikrini esengeziwe se-OCV ngaphambi kokuthunyelwa ukuze babambe noma yimaphi amaseli awonakaliswe kakhulu. Hhayi kahle kodwa ezomnotho ziyilokhu abayikho.

Hambisa iseli elibandayo ulifake ekamelweni elifudumele futhi amanzi ahlangane phezulu. Wonke umuntu uyakwazi lokhu. Okungaqapheli wonke umuntu ukuthi kubaluleke kangakanani lokhu kumaseli esikhwama. Amanzi efilimu ye-aluminium laminate akuyona nje indaba yezimonyo. Ingena kuma-welds wethebhu. Ibangela i-oxidation. Ezimweni ezimbi umswakama usebenza ngendlela yawo ngokusebenzisa uphawu lokushisa futhi usabela ne-electrolyte.

Indlela efanele yokusingatha lokhu indawo yebhafa. Amaseli ahlala ekamelweni lokushisa eliphakathi amahora amane kuya kwayisithupha ngaphambi kokuthuthela endaweni yokukhiqiza. Amazinga okushisa ayalingana kancane kancane. Akukho ukujiya.

Imisebenzi emincane yeqa lesi sinyathelo. Ngavakashela isitolo esisodwa sokuhlanganisa amaphakethe lapho babedonsa khona amaseli besuka endaweni epholile eyi-5℃bawayise endaweni yokusebenzela engu-30 degree. Maphakathi no-August. Yonke indawo yeseli yayimanzi. Umphathi wokukhiqiza uvumile ukuthi izinga lokwenqatshwa kwemojuli yokushisela laliphezulu ngaleyo nyanga. Usole imishini yokushisela. Nganginombono wami siqu.

Izinyanga eziyisithupha ziwumkhawulo ojwayelekile. Ngemuva kwalokho udinga ukuphinda uhlole. I-OCV, i-IR, umthamo, i-suite yonke. Amaseli ahlulekayo ehliswa noma alahlwe. I-EVE kuthiwa idinga amaseli agcinwe ngaphezu kwezinyanga eziyisishiyagalolunye ukuthi abuyele efekthri ukuze aphinde{4}afakwe esigabeni. Angikakuqinisekisa lokhu ngqo kodwa kuvele kumuntu ozokwazi.

Lokhu kwaba ikhanda langempela lapho imakethe ye-ESS yehla ngasekupheleni kuka-2023. Abahlanganisi babehlezi ku-inventory abakwazanga ukunyakaza. Amaphrojekthi ayelokhu ebambezeleka. Ngesikhathi amadili evalwa, amaseli ayesedlule iwindi lawo lesitoreji. Capha izinyanga zezingxabano phakathi kwabahlanganisi nabahlinzeki beselula mayelana nokuthi lokhu bekuyinkinga kabani. Izinkontileka zokuthenga manje ngokuvamile zihlanganisa ulimi oludinga ukuthi amaseli enziwe phakathi kwezinsuku ezingu-60 noma ezingu-90 zokulethwa. Isifundo esitholiwe.

Izifafaza ezijwayelekile ze-warehouse azisebenzi kahle emlilweni webhethri le-lithium. Amanzi ashaya iseli ekubalekeni okushisayo angenza izinto zibe zimbi nakakhulu. Ikhiqiza i-hydrogen. Amasistimu akhethwayo manje ayi-perfluorohexanone noma inkungu yamanzi ahlanzekile, kodwa ukusethwa kwe-perfluorohexanone kubiza izigidi zama-RMB. Izitolo eziningi azikwazi ukukuthethelela lokho kuchithwa.

Umshwalense usuphenduke umgoqo omkhulu. I-CPIC kanye ne-Ping Zombili izilinganiso ezikhuphukile zokugcinwa kwebhethri le-lithium kusukela ngo-2024. Iphinda kathathu kuya kwezine imali ekhokhwa yi-warehouse evamile, kulokho engikuzwile. Abanye abadayisi bomshwalense ngeke bawathinte nhlobo la maphrojekthi. Ngaphandle kokufakwa komshwalense, inhlanhla yokuthola uxhaso lwebhange. Yonke into eya phansi iyabhajwa.

Amaseli adinga ukuhlolwa kwamandla kagesi ngezikhathi ezithile ngenkathi egcinwe. Ukuzikhipha okuvamile{1}}kungamamilivolthi ambalwa ngenyanga. Uma ubona iseli lehla ngo-15mV noma ngaphezulu, cishe kukhona okungalungile ngaphakathi. I-Micro short circuit cishe. Likhiphe nibhekane nalo ngokwehlukana.

Amakhasimende ase-Europe afuna ukubona izingodo zokushisa zaso sonke isikhathi sokulondoloza. Ezinye izindawo zokugcina izimpahla zinamathisela abagawuli bedatha kuphalethi ngayinye ehamba nokuthunyelwayo. Ikhasimende lidonsa idatha ekutholeni. Okukodwa{3}ku{4}}kuhambo oluthile olukuleyo log futhi bangase banqabe yonke inqwaba. Kwenzeke kumthumeli engimaziyo. Iziqukathi{7}ezingamashumi amane ezijike ethekwini.

I-FIFO kufanele ibe lula. Okokuqala, ukuphuma kuqala. Empeleni, abashayeli be-forklift babamba noma iyiphi i-pallet okulula ukuyifinyelela. Izinto ezingemuva kwe-rack zihlala lapho izinyanga kuze kube yilapho othile eqaphela. Izinhlelo ze-MES ziyasiza uma unazo. Izitolo eziningi zisasebenza kuma-spreadsheet futhi zithemba okungcono kakhulu.
