I-Opportunity Charging isebenza kanjani kumabhethri e-lithium?

Ithuba lokushaja lisho ukuxhuma ibhethri le-lithium ngesikhathi sekhefu esikhundleni sokukhipha-umjikelezo wokushaja ogcwele. Ibhethri lihlala elolini. Abasebenzisi bayayigcwalisa noma nini lapho bengasebenzisi okokusebenza-kwasemini, ukushintsha kweshifti, ukulinda i-trailer. I-SOC intanta ebangeni lama-40-70% usuku lonke.

Ngomthofu-lokhu kulimaza ibhethri. I-Sulfation kusuka ekushajeni ingxenye. I-Lithium ayinayo leyo nkinga. Amaseli e-LFP empeleni ahlala isikhathi eside uma uwagcina emaphakathi-nobubanzi.

Nansi into emayelana nomthofu-i-asidi abantu abangaphandle komkhakha abangayazi ngokugcwele: ukushaja kwezinto kuyiphupho elibi.

Iphakethe-le-asidi eliholayo le-forklift enkulu ye-counterbalance linesisindo esingu-2,500 pounds, kwesinye isikhathi ngaphezulu. Awukwazi ukuvele ulishiye elolini bese uxhuma ubusuku bonke ngoba iloli lidinga ukusebenzisa ishifu elandelayo. Ngakho-ke ukhipha ibhethri-udinga i-hoist noma i-roller stand yalelo{6}}isondo elilifaka egunjini lokushaja, lixhume, bese ulinda. Amahora ayisishiyagalombili ukushaja, kuzomele kuphole noma uyakulimaza. Ibize amahora ayishumi okungenani ngaphambi kokuba lelo phakethe lilungele ukubuyela elolini.

Ukusebenza kwamahora angu-24-kudinga amabhethri amathathu iforklift ngayinye azungezisayo: elilodwa elolini, elilodwa liyashaja, elilodwa lokupholisa. Phind Iwumsebenzi wonke.

I-lithium enethuba lokushaja: ibhethri elilodwa elolini ngalinye. Alikho igumbi lokushaja. Abekho abajokhi bebhethri. Ama-opharetha axhuma ikhebula lapho behamba ngekhefu. Kwenziwe.

Ngasebenza nge-retrofit e-DC yegrosa e-Ohio emuva ngo-2019. Babenama-forklift angu-68, ingxube yamaloli afinyelelekayo kanye namabhalansi, egijima amashifu amabili neqembu lamathambo endaweni yesithathu. Ukusethwa kwe-asidi eholayo{3}. Igumbi lokushaja lalingamamitha-skwele angu-4,000. Lapho sishintshela ku-lithium, lokho kwaba yindawo yokuqopha. Bacosha okuthile okufana nezindawo zephalethi ezingama-800. Indawo yomphathi webhethri yasuswa{11}}leya nsizwa yathuthela ekwamukeleni. Iphrojekthi yonke ikhokhelwe ngaphansi kweminyaka emibili, futhi lokho akubali ngisho nokwehliswa kwesondlo.

Udinga amandla aphezulu kunokushaja ebusuku. 100-200Okungenani kwamaloli e-Class I, afana no-200-350A kubafana abakhulu.

UFronius wenza amayunithi amahle. Inani kodwa lithembekile. Sibe nenhlanhla nge-Delta-Q ezintweni ezincane. Gwema ukungeniswa{4}kwamagama ngaphandle uma uvumelana nezimangalo zewaranti ezingena emgodini omnyama.

Ishaja kufanele ikhulume ne-BMS. Ukushaja kwe-lithium akukhona nje okwamanje okungashintshi kuze kugcwale-i-BMS ilawula ijika lokushaja, ibhalansi amaseli, iphatha imikhawulo yokushisa. Ishaja eyisimungulu eshaya indiva imiyalo ye-BMS izoshaja kancane kakhulu noma ilimaze iphekhi. Ukuxhumana kwe-CAN kujwayelekile. Uma othile ezama ukukudayisela ukusethwa kwe-lithium ngaphandle kokuhlanganiswa kweshaja ye-BMS-hamba.

Hhayi egunjini lokushaja. Iphuzu eliphelele liwukusabalalisa ukuze ukuxhuma kulunge.

Ilayisha amadokhu, ukuphela kwamaphasishi, indawo yegumbi lokuphumula. Noma yikuphi amaloli ahlala imizuzu engaphezu kwemihlanu. Uma uyenza lula, kulapho ama-opharetha akwenza kakhulu. Imvelo yomuntu.

Amandla kagesi yisona sici esingacabangi muntu kuze kube yinkinga. Izakhiwo ezindala ngokuvamile azikwazi ukusekela{1}amashaja kagesi aphezulu ayishumi ahlakazekile ngaphandle kokuthuthukiswa kwamaphaneli. Sibe nephrojekthi ePennsylvania lapho sicabangele iziteshi zokushaja eziyisishiyagalombili futhi isevisi kagesi yebhilidi ingakwazi ukubhekana nezine ezisebenza ngasikhathi sinye. Igcine ngokufaka amashaja okuphatha{4}}okukhuluma nesilawuli esiwanyakazisayo ukuze ungalokothi weqe umkhawulo wokufunwa. Kwengezwe u-$15K kuphrojekthi kodwa ishibhile kune-transformer entsha.

Uhlelo lokuphatha ibhethri ubuchopho. Iqapha wonke amaseli, ilawula ukushaja, iphatha ukulinganisa, ifaka yonke into.

Ngeke ngijule ekwakhiweni kwe-BMS lapha. Uma uhlola amaphakethe, into esemqoka okufanele uyibheke ukuphatha okushisayo. Amaphakethe ashibhile ayakweqa kulokhu. Amaseli alungele ukushaja ithuba-kuyiphekhi{4}}idizayini yezinga lokushisa elibalulekile. Buza umthengisi ukuthi kwenzekani uma uphusha u-200A ephaketheni ngo-35℃ambient. Uma bengakwazi ukukunikeza impendulo ecacile, lokho ifulegi elibomvu.

Lokhu kufanele esakho isigaba ngoba wuhlelo olulodwa lapho ukushaja kwamathuba kuba nzima khona.

I-Lithium ibamba ukubanda kangcono{{0}kune-asidi yomthofu. Yiqiniso. Kodwa ukushaja ibhethri elibandayo kuyindaba ehlukile. Ngaphansi kwamadigri angu-5 kufanele wehlise inani lamanje kakhulu noma uzifaka engozini ye-lithium plating, elimaza unomphela amaseli. Ngaphansi kuka-0℃izinhlelo eziningi ze-BMS ngeke zivumele ukushaja sanhlobo.

Ngakho-ke une-forklift esanda kuchitha amahora amane -esiqandisini esingu-20 degree. Ibhethri licwiliswe ngamakhaza. Uyikhiphele edokini ukuze uyishaje futhi iBMS ithi cha. Manje yini?

I-workaround iwukushaja endaweni epholile. Ezinye izingosi zakha umpheme emnyango wesiqandisi lapho amaloli egibela khona ngaphambi kokungena. Izinga lokushisa le-ambient, mhlawumbe 10-15℃. Ibhethri liyafudumala ngenkathi opharetha enza amaphepha noma yini. Emaminithini angamashumi amabili kamuva kufudumele ngokwanele ukwamukela inkokhiso.

I-Lineage Logistics ibikuthola lokhu njengoba iguqula izindawo zayo. Kuyaxazululeka kodwa kufanele ukuhlelele. Abantu abaningi bacabanga ukuthi i-lithium iyipulaki-futhi-bayadlala bese bayamangala lapho umkhumbi wesiqandisi ungakhokhi.

Amaphekhi e-lithium abiza cishe ngokuphindwe ka-3 inani le-asidi-ebiza kusengaphambili. Leyo inombolo wonke umuntu ayilungisayo.

Abakugejayo: uthenga iphakethe elilodwa esikhundleni samathathu. Awulakhi igumbi lokushaja. Awukhokhi umuntu ukuthi ashintshe amabhethri. Awuthengi okokukhipha ibhethri ngo-$8,000. Awubhekene nokuchitheka kwe-asidi, ukuchelela, izindleko zokulinganisa, izinkinga ze-sulfation.

I-TCO eminyakeni emihlanu, i-lithium iwina kuma-shift amaningi-ezinhlelo zokusebenza eziningi. Hhayi ngisho eduze. Imisebenzi yeshift eyodwa-izibalo ziyaqina-kwesinye isikhathi ukuhola-i-asidi isezwakala uma ukusetshenziswa kuphansi.

Cha. Ngokuphambene.

Amaseli e-Lithium-i-LFP ikakhulukazi-ahlala isikhathi eside uma uwagcina emaphakathi nebanga lokushaja. Ukukhishwa okujulile kugcizelela i-anode. I-SOC ephezulu igcizelela i-cathode. Ukuntanta ebangeni lama-30-70% yindawo emnandi. Yilokho kanye okwenziwa ukushaja ithuba.

Ukushisa okuvela-kokushaja kwezinga eliphezulu kuyisici kodwa kuyalawuleka ngedizayini ehloniphekile ye-thermal. 0.4C ayinalo udlame ku-LFP. Ngibone amaphekhi asebenzisa ithuba elingu-0.5C eshaja iminyaka ngokonakaliswa okuncane.

Uma sibheka emuva kumaphrojekthi eminyakeni emihlanu edlule, amaphutha avame ukufana.

Ukulinganisa izidingo zikagesi. Njalo thola inhlolovo yesayithi ngaphambi kokuthi uzibophezele kusakhiwo seshaja. Njalo.

Ayibandakanyi ukulungiswa kusenesikhathi. Amadoda akho esondlo ayazi lapho amaloli ehlala khona engenzi lutho. Babuze ngaphambi kokukhetha izindawo zeshaja. Idokhi yokulayisha ingase ibonakale isobala kodwa uma amaloli ehlala edlula lapho, akekho ozoxhuma.

Kushibhile ngamashaja. Iyunithi engu-$2,000 evela ku-Alibaba ayilingani ne-$6,000 kaFronius. Uzothola indlela enzima.

Hhayi ukuqeqesha ama-opharetha. Kuzwakala kuyisisekelo kodwa abantu abaxhumi uma bengaqondi ukuthi kungani kubalulekile. Imizuzu emihlanu emhlanganweni wasekuseni ochaza umqondo uhamba ibanga elide.

I-asidi-yomthofu ayifile kodwa ngokusobala isiyindlela yefa manje. Ama-OEM wonke aphusha i-lithium. I-Toyota, Crown, Hyster{3}}ukuthengiswa kwabo kwe-lithium kukhula ngokushesha kune-acid-yomthofu kuyo yonke imigqa yomkhiqizo.

Ingxenye yayo ingcindezi yokusimama. I-Lithium inendaba yomjikelezo wempilo engcono. Ingxenye yawo umsebenzi{2}}akekho ofuna ukusebenzisa igumbi lebhethri. Ingxenye yakho iwukuba lula kokusebenza. Uma isayithi liguquka futhi libona ukuthi kulula kangakanani, alibuyeli emuva.

Imishini isacwengwa. Amashaja aya ngobuhlakani, amasistimu e-BMS aba ngcono, imiklamo yokupakisha eshisayo iyathuthuka. Eminyakeni emihlanu kusukela manje konke lokhu kuzobe sekuvuthiwe. Kodwa okuyisisekelo-ibhethri elilodwa, akukho ukushintshaniswa, ukushaja uma ingenzi lutho{4}}lokho akushintshi.
