Ngibe kule mboni iminyaka eyishumi nambili, futhi ngokweqiniso, iningi lemihlahlandlela yebhethri ye-lithium laphaya ayinamsebenzi ezinqumweni zangempela zokuthenga. CC{{1}Izimiso ze-CV, imikhawulo yezinga lokushisa, 80% ukushaja okungajulile... ungathola konke lokhu eBattery University. Asikho isidingo sokuthi ngiphinde.
Engifuna ukukuxoxa namuhla yimibuzo eyenza amaqembu okuthenga aphathwe yikhanda:Indlela yokukhetha umthamo, indlela yokufanisa amashaja, yini ukutshalwa kwezimali okunengqondo, nokuthi uzobona nini i-ROI.Azikho izimpendulo ezijwayelekile, kodwa ngingabelana ngedatha yangempela evela kumaphrojekthi ethu kanye namaphutha esiwenzile endleleni.
Ingemuva elisheshayo: Ngingunjiniyela wohlelo lokusebenza e-[igama lenkampani lenziwe kabusha ukuze kugwenywe ukubukeka njengesikhangisi], ikakhulukazi ngisebenza kumaphrojekthi wokufaka ugesi ezimotweni zezimboni eMpumalanga naseNingizimu China. Nginolwazi oluncane ngezimo zezulu ezibandayo enyakatho, ngakho iziphakamiso zami zingase zingasebenzi ngokugcwele uma usebenzisa indawo yokugcina impahla efrijini e-Harbin.
Ukukhetha Amandla: Kuyinkimbinkimbi Kakhulu Kunokuba Ucabanga
Umbuzo ovame kakhulu engiwutholayo uthi "Ingabe i-400Ah yanele?" Angikwazi ukuphendula lokho ngqo ngoba "kwanele" kuncike ezintweni eziningi eziguquguqukayo.
Bala ukusetshenziswa kwamandla kwansuku zonke kuqala. Ungakweqi lokhu.
Ukusetshenziswa kwansuku zonke (kWh)=Amandla amaphakathi (kW) × Amahora okusebenza (h) × Isici somthwalo
Isici somthwalo sincike ezimweni zangempela zokusebenza: umsebenzi olula 0.3~0.4, omaphakathi 0.5~0.6, osindayo 0.7~0.8. Abantu abaningi bayamosha lokhu ngokusebenzisa amahora alinganiselwe wezikhathi zamandla, okunikeza izinombolo ngo-30%+ ngaphezu kweqiniso.
Isibonelo:I-forklift kagesi yamathani angu-2, amandla alinganiselwe angu-8kW, asebenza amahora angu-10 nsuku zonke, umthwalo ophakathi.
Ukusetshenziswa kwansuku zonke=8 × 10 × 0.55=44kWh
Kusistimu ye-48V, i-44kWh ihambisana cishe ne-920Ah. Njengoba kungafanele ukhiphe ngaphansi kuka-20%, umthamo osebenzisekayo cishe u-80%, okusho ukuthi udinga cishe u-1150Ah ukuze uqede usuku ngenkokhiso eyodwa.
Kodwa lokho kungumbono nje.
Kumaphrojekthi wangempela, ngithole igebe phakathi kokusetshenziswa okubaliwe nokusetshenziswa kwangempela kuvame ukuba ngu-15% ~ 25%. Izizathu ziyahlukahluka: imikhuba yabasebenzisi, imithambeka yaphansi, ukuguquguquka kwesisindo sempahla, ukusetshenziswa kwe-HVAC... Ngakho-ke isincomo sami:engeza u-20% webhafa ngemva kokubala inani lethiyori, noma uqashe amayunithi ambalwa inyanga-yokuhlola umhlaba wangempela kuqala.
Ingabe enkulu ihlala ingcono? Akunjalo.
Ngonyaka odlule iklayenti labala ukusetshenziswa kwansuku zonke okungu-50kWh kodwa laphikelela ekuthengeni amabhethri angu-1500Ah ngoba "singase sikhule futhi ngeke kudingeke siwashintshe ngokuhamba kwesikhathi." Kwenzenjani?
Inkinga 1
Ibhethri elikhudlwana lengeze u-60kg, okuphoqe ukuthi i-forklift isebenze ngomthamo oncishisiwe wemfoloko
Inkinga 2
Amandla eshaja kwadingeka athuthukiswe ngokufanele, kanye nezindleko zokunwetshwa kwengqalasizinda kagesi
Inkinga 3
Umthamo webhizinisi awuzange ukhule. Ibhethri lichithe isikhathi salo esiningi lintanta phakathi kuka-30%~60% SOC, empeleni lisheshisa ukuguga kwekhalenda
Umbono wami:Uma ivolumu yebhizinisi yamanje izinzile, khetha umthamo ohlangabezana nezidingo zakho (inani lethiyori + 20% sebhafa). Uma inganele eminyakeni emithathu kuya kwemihlanu, yishintshe ke. Lokhu kungase kube ukonga kakhulu kunokukhulisa kakhulu ngaphambili. Ubuchwepheshe bebhethri buthuthuka ngokushesha. "Umthamo omkhulu" oyikhokhayo namuhla ungase ube yintengo-eminyakeni emihlanu.
Yiqiniso, lokhu kungumbono wami nje. Uma unesabelomali, isikhala siyakuvumela, futhi uyazethemba ngokukhula, ukuthenga okukhudlwana akulona iphutha.
Ireferensi yezindleko zokucushwa okujwayelekile
Idatha engezansi ivela kumaphrojekthi wethu ka-2024~2025 e-East China, ikakhulukazi evela kubasabalalisi be-CATL nabakwa-EVE. Izintengo zishintsha njalo ngekota, ngakho izingcaphuno zakho zangempela zingahluka.

Ukukhetha Ishaja: Lapho Izinkinga Eziningi Zenzeka Khona
Ibhethri likhethiwe, vele ubambe noma iyiphi ishaja? Leli iphutha elivamile. Cishe u-30% wamacala okuhluleka engiwaphethe ayehlobene-neshaja.
Ukufanisa i-voltage akulula kangako
Amabhethri wonke abhalwe ukuthi "48V" angaba nama-voltages ahluke kakhulu wokunqamula ukushaja:
| Uhlobo Lwebhethri | Amaseli | Ukuqedwa Kweseli | Ukuqedwa Kwephakethe |
|---|---|---|---|
| I-NCM Ternary | 13S | 4.2V | 54.6V |
| I-LFP (Iron Phosphate) | 15S | 3.65V | 54.75V |
| I-LFP (Iron Phosphate) | 16S | 3.65V | 58.4V |
Amashaja e-15S kanye ne-16S LFP AKUKHO ukushintshaniswa. Ngike ngabona amakhasimende ezama ukonga imali esebenzisa ishaja ye-15S kumabhethri e-16S. Umphumela: awulokothi ukhokhise u-85% we-SOC. Okuhlehlayo kuyingozi kakhulu: Ishaja ye-16S kumabhethri e-15S ibangela ukushajwa ngokweqile okuqondile.
Njalo qinisekisa inani lamaseli ngesikhathi sokuthenga. I-voltage yegama iyodwa ayanele.
Izimiso zokuxhumana ziyizinxushunxushu ngokweqiniso
Ngokombono, amashaja anokuxhumana kwe-CAN angasebenzisana ne-BMS-esikhathini sangempela, aguqule ngokuguqukayo amapharamitha wokushaja ngokusekelwe esimweni sebhethri. Ngokusebenza:
Abakhiqizi abahlukene basebenzisa amaphrothokholi ahlukene wesendlalelo sohlelo lokusebenza. I-CAN 2.0 icacisa kuphela isendlalelo esibonakalayo. Okwenzeka ngenhla kuqondile-umthengisi.
Izimo engihlangabezane nazo:
- Ibhethri le-Brand A elineshaja ye-Brand B: CAN cable ixhunyiwe, kodwa ukuxhawula kwehluleka. Ugcine ngokuyisebenzisa "njengeshaja eyisimungulu"
- Umhlinzeki uthi "i-GB/T 27930 iyahambisana," kodwa imisebenzi eyisisekelo kuphela esebenzayo. Imiyalo enwetshiwe ayisekelwe nhlobo
- Umkhiqizi webhethri uyenqaba ukwabelana ngamadokhumenti ephrothokholi, ecaphuna "izimfihlo zohwebo"
Isiphakamiso sami:
Uma ungafuni ubuhlungu bekhanda, thenga ibhethri neshaja kumkhiqizo ofanayo, noma uthole iziqinisekiso ezibhaliwe zokusebenzisana nemibiko yokuthumela evela kubahlinzeki. Imali oyilondolozayo ngokuthenga ngokuhlukene ingase ingafaki izindleko zokulungisa iphutha kamuva.
Sekushiwo lokho, uma unonjiniyela bakagesi abakwazi ukuzibamba ngokwabo ukuhlanganiswa kwephrothokholi, ukuthenga okuhlukene kungonga u-15% ~ 20%.
Indlela yokukhetha izinga lokushaja
Ngibuzwa lokhu kakhulu, ngakho nansi impendulo yami ebumbene:
| Isimo | Isilinganiso Esinconyiwe | Amanothi |
|---|---|---|
| Ishifti eyodwa, iwindi lokushaja lamahora angu-8+ ngobusuku | 0.3C~0.5C | Ukushaja okunensayo kungcono kakhulu kumabhethri |
| Ukushintsha kabili, ukushaja ngesikhathi sasemini nasebusuku | 0.5C~0.8C | Ibhalansi phakathi kwejubane nokuphila isikhathi eside |
| Ukushintsha kathathu okuqhubekayo, izikhala ezimfushane kuphela | 1C | Ithuba lokushaja izimo |
| Isimo esiphuthumayo | 1.5C | Ukusetshenziswa ngezikhathi ezithile kuphela, hhayi ukwenza okujwayelekile |
Ukushaja okusheshayo ngaphezu kwe-1C kuyakusheshisa ukuwohloka kwebhethri, kodwa yimalini ngempela? Thembeka,imboni ayikafinyeleli ekuvumelaneni. Idatha yelebhu yabakhiqizi abathile ibonisa umehluko omncane, kodwa kumaphrojekthi wethu wangempela siye sabona ukuwohloka konyaka okwengeziwe okungu-1%~1.5% ku-1C eqhubekayo uma kuqhathaniswa no-0.5C. Usayizi wesampula usakhawulelwe; thatha lokhu njengesithenjwa kuphela.
I-ROI: Ungakhohliswa Izinombolo Ezikahle
