Kutheni i-Sub -i-Zero Engqongileyo ifuna indlela eyahlukileyo kuMbane weBhetri
Kwi- - 20℃, i-lead-acid forklift ibhetri ihambisa ngaphantsi kwesiqingatha somthamo oshicilelweyo kwi-nameplate yayo. Loo nyaniso inye ilungisa yonke into malunga nobungakanani bezithuthi, isicwangciso sokutshintsha, kunyeixabiso lilonke lobuninikwimisebenzi yokugcina ebandayo.
Yonke indawo yokugcina impahla isebenza ngeebhetri. Kodwa ugcino olubandayo aluyiyo enye indawo yokugcina impahla. Luvavanyo loxinzelelo lwe-electrochemical ukuba uninzi lweenkqubo zebhetri azizange zenzelwe ukuba zidlule. Nantsi into eyenzekayo ngaphakathi kwebhetri yeforklift xa amaqondo obushushu okugcina ehla ngaphantsi komkhenkce. I-electrolyte, nokuba i-asidi yesulfuric kwilothe{4}}iiseli zeasidi okanye isisombululo setyuwa ye-lithium kwiipakethe ze-ion zeLi -, iba viscous ngakumbi. I-electrolyte etyebileyo ithetha ukuba iiyoni zihamba kancinci. Ukuthutha i-ion ephantsi kuthetha ukuchasana okuphezulu kwangaphakathi. Kwaye ukuxhathisa okuphezulu kuguqulela ngokuthe ngqo kumandla angaphantsi akhoyo, amaxesha amade entlawulo, kunye nokuthotywa okukhawulezileyo. I-cascade iqala ngexesha lobushushu be-ambient lehla ngaphantsi kwe-15 degree.
Oku kubalulekile ngoku kuba umthamo wokugcina obandayo ukhula ngokukhawuleza. Imakethi yehlabathi yokugcina ebandayo ifikelele malunga ne-185.75 yeebhiliyoni zeedola ngo-2025 kwaye kulindeleke ukuba ikhule kwi-CAGR ye-11.8% ukuya ngo-2033 (UPhando oluNgcono olukhulu). Iindawo ezininzi zokugcina izikhenkcisi zithetha iiforklift ezininzi ezisebenza phantsi{1}}zero iimeko, kunye nemisebenzi emininzi ejongene nemingeni yobushushu bebhetri abangakhange bayicwangcise.
Umgaqo kabhontsi othi-ucatshulwa rhoqo uthi ibhetri iphulukana nomthamo oyi-1% womthamo wayo ngokweqondo elingaphantsi kwe 30℃. Kodwa elo nani lifihla ngaphezu kokuba likutyhila. Iiseli ze-LFP zilahlekelwa malunga ne-6% nge-0 degree. I-asidi yesiqhelo - sele iku-25% ilahleko kwindawo enye yobushushu. Ngezantsi -i-10℃, zombini iigophe azihambi ngendlela, kwaye i-1%-nge-degree-experimation ye-degree iyayeka ukusebenza kuyo nayiphi na ichemistry (Forkliftaction).
Iindleko ezifihlakeleyo: Indlela yokubanda ebulala ngayo iibhetri zeForklift (kunye nohlahlo-lwabiwo mali lwakho)
Inani lesihloko uninzi lwemisebenzi ejolise kuyo kukuphulukana nomthamo, kwaye kubi ngokwaneleyo. Ibhetri yeforklift yeasidi egcweleyo -esebenza kwi-0℃inikezela kuphela malunga ne-75% yomthamo wayo okaliwe. Kwi-12 degree, oko kuhla ukuya kwi-56%. Kwi--18℃, yehla ukuya kwi-45%. Ezi ayizizo iimeko; ziyinyani yemihla ngemihla yokusebenza kwebhetri yeforklift kwindawo yokugcina ebandayo efrijini kunye neendawo ezinomkhenkce (MHLNews).
Kodwa ukulahlekelwa kwamandla kuphela yingxaki ebonakalayo. Kukho ubuncinci ezinye iindlela ezintathu zokungaphumeleli ezithi cwaka zidibanise umonakalo, kwaye zizo eziphela zixabisa ngaphezulu ekuhambeni kwexesha.
Eyokuqala yile nto amagcisa ayibiza ngokuba “ngumgibe wokufunda okungeyonyani”. Xa ubushushu bangaphakathi bebhetri{1}yeasidi buhla, amandla ombane afundeka phezulu kuneyona meko yentlawulo. Isalathisi sokukhupha i-forklift sixelela umsebenzisi ukuba ibhetri ikwi-60% xa inokuba kwi-35%. Okubi nakakhulu, itshaja ifunda la mandla ombane anyusiweyo kwaye iwuphelise kwangoko umjikelo wentlawulo, ukholelwa ukuba ibhetri igcwele. Isiphumo kukutshaja ngaphantsi okungapheliyo, inguqu emva kweshifti, de amandla asebenzayo ebhetri ancitshiswe ngokusisigxina. Isilumkiso kwangethuba uninzi lwabasebenzisi bayaphoswa: iiforklift ziqala ukusweleka phakathi-ishifti kwiibhetri ezixelwe ukuba zigcwaliswe ngokupheleleyo phambi kokuba kuqale utshintsho. Ukuba oku kwenzeka ngaphezu kweveki enye, umjikelo wokufunda ongeyonyani usenokuba sele ucuthile umthamo osebenzayo nge-15–20%.
Ixabiso lesibini elifihliweyo kukukhenkceza kwe-electrolyte. I-lead ekhutshiweyo-ibhetri yeasidi ine-electrolyte exutywe neqondo lomkhenkce elinokunyuka liye kutsho ku -7℃. Kwisikhenkcisi se-20 degree, loo electrolyte iyaba ngumkhenkce kwaye yande, iipleyiti eziqhekekileyo kunye ne-warping casing. Lo ngumonakalo ongenakulungiseka kwisakhiwo, hayi idiphu yokusebenza onokubuyela kuyo ngokufudumeza ibhetri.
Ucondensation: Kutheni Iibhetri Ezingakumbi Zisilela kwiDokhi yokuLayisha kunesikhenkcisi
Amanqaku amaninzi malunga nokuthintela ibhetri ye-forklift kwi-condensation yokugcina ebandayo igxininise kubanda ngokwayo. Kodwa ekusebenzeni, iibhetri ezininzi zonakaliswa lutshintsho phakathi kweendawo ezibandayo nezifudumeleyo kunobushushu obuphantsi obuzinzileyo kuphela.
Xa i-forklift iqhuba ukusuka kwi-25℃efrijini ukuya kwi-dock yokulayisha i-20 degree, umahluko weqondo lokushisa ubangela ukuxinana ngokukhawuleza kwindawo yonke, kubandakanywa iitheminali zebhetri, izixhumi zekhebula, iibhodi zesekethe, kunye nengaphakathi kwendawo evalelwe ibhetri. Amathontsi amanzi enza kwimizuzu embalwa. Kunxibelelwano lombane, oko kufuma kudala iindlela zeesekethe ezimfutshane kwaye kukhawulezisa ukubola. Kwiibhodi zeesekethe, kunokubangela ukungaphumeleli kwecandelo ngokukhawuleza.
"Oku akusiyo ithiyori. Ityala elibhalwe kwiforum yeshishini leForkliftaction lichaza umsebenzi wokugcina obandayo eVietnam aphoukufikelela kwiiloringokwesiqhelo ukusuka -25 idigri yogcino ukuya ngqo kwindawo yokulayisha iqondo lobushushu. Ngaphandle kwendawo yesithinteli phakathi kweendawo zobushushu, ikhompatimenti yemoto yombane kunye neebhodi zolawulo ziye zafumana ukujiya okuqatha. Iiyunithi ezininzi ziye zafumana ukusilela kwebhodi yolawulo ezathi zafunyaniswa gwenxa ekuqaleni njengeziphene zokuvelisa. Oyena nobangela yayikukusingqongileyo ngokupheleleyo, kwaye unokuthintelwa ngokupheleleyo ngoyilo olufanelekileyo lwendawo (IForam yeForkliftaction)."
Ukuthintela ukujiya kufuna indlela eyakhiweyo. Icala loncedo lifuna iindawo ezithintelweyo, izithuba zotshintsho ezigcinwe kwiqondo lobushushu eliphakathi apho izixhobo zinokutshona kangangemizuzu eyi-10 ukuya kweli-15 ngaphambi kokungena okanye ukuphuma kwindawo ebandayo. Icala lebhetri lifuna i-IP67-iindawo ezivaliweyo ezivala ukufuma, ezidityaniswe ne-silica gel dessiccants efunxa nayiphi na i-condensation eyenziwa emoyeni. Kwaye icala elisebenzayo lifuna iiprothokholi ezithintela ukutshaja ngoko nangoko emva kwengqele{7}}ukuya{8}}inguqu eshushu, kuba izihlanganisi ezinobumanzi obungaphezulu zinokutshisa kakhulu kwaye zingasebenzi ngexesha lokutshaja okuphezulu.
Kwiindawo esizivavanyileyo, umgca wokwahlula uyahambelana: imisebenzi enyanzelisa ubuncinci be-5-iprothokholi yemizuzu emi-5 kunye nokusebenzisa i-IP67-indawo ezivaliweyo zebhetri zibone imiba yazo yokuqala yesiqhagamsheli sokudleka kuphawu lweminyaka emi-5. Imisebenzi etsiba i-acclimation kunye nokuhlawulisa ngokukhawuleza emva kweenguqu ezibandayo ukuya kukufudumala, uninzi lwazo ngaphambi kokuba sibandakanyeke, zibonisa ukungaphumeleli komhlwa kwiinyanga ezili-18 ukuya kwezingama-24. Imowudi ethile yokungaphumeleli iyahluka ngokubala komjikelo wobushushu bemihla ngemihla kunye nokufuma kwendawo, kodwa ipateni icacile xa sele uyibonile kwiindawo ezaneleyo.
ILithium vs Lead{0}}I-Acid kwiNdawo yesiQinisekiso esiNto ebandayo: Eyona nto iboniswa yiData
I-lithium-nxamnye-nenkokeli-incoko yeasidi kwindawo yokugcina ebandayo ilawulwa ngamabango okuthengisa macala omabini. Nantsi into esixelelwa yidatha elinganisiweyo kuwo wonke amaqondo obushushu athile.
Kwi-degree ye-0, iiseli ze-LiFePO4 ezivavanywe kwizinga lokukhutshwa kwe-1C zibonisa ukunciphisa umthamo malunga ne-6.4%. Kwakwiqondo lobushushu elifanayo, iibhetri ze-lead{5}}ze-asidi sele zilahlekelwe ngama-25% okanye ngaphezulu komthamo wazo olinganisiweyo (ScienceDirect). Lo msantsa ukhula ngokumangalisayo njengoko amaqondo obushushu ehla ngakumbi. Iibhetri ze-LFP ezinolawulo lwe-thermal zigcina amandla okukhutshwa okusebenzayo ukuya kuthi ga kwi- - i-20℃. Iibhetri ze-lead-asidi kobo bushushu zisebenza ngaphantsi kwesiqingatha somthamo wazo obekiweyo, ukuba zisasebenza kwaphela.
Ubomi bomjikelo bubalisa ibali elibukhali ngokulinganayo. Kwiimeko zogcino olubandayo,{1}}ibhetri yeasidi ikholisa ukuzisa ama-500 ukuya kwi-1,000 lemijikelo phambi kokuba ifune ukutshintshwa, malunga neminyaka emi-2 ukuya kwemi-3 yenkonzo. Iipakethe ze-LiFePO4 kwindawo efanayo zifikelela kwi-2,500 ukuya kwi-4,500 imijikelezo, ukuguqulelaIminyaka emi-5 ukuya kwe-7 yobomi bokusebenza. Kodwa la manani acinga ukuba ulawulo lwe-thermal lugcina ubushushu beseli ngaphezulu kwe-0℃ngexesha lokutshaja. Ngaphandle kwayo, ubomi bomjikelezo we-lithium kwizicelo zefriji bunokwehla ngaphantsi kwee-1,500 cycles, engekude nommandla we-TPPL, ngexabiso eliphindwe kathathu lokuthenga.
Xa uvavanya ibhetri ye-lithium forklift yokugcina ebandayo, iindleko ezipheleleyo zobunini yinto ebalulekileyo. Into ekuphelisweni kweziseko ezingundoqo zokutshintsha ibhetri kunye ne-41% yokwehliswa kweendleko zombane ezibhalwe kwindawo yokugcina ebandayo{2}}iasidi{3}}ukuya{4}}kuguqulo lwe-lithium (Iindaba zeForkliftaction), kwaye i-equation itshintsha kakhulu kwi-lithium, ibonelele ukuba ibhetri inolawulo olufanelekileyo lwe-thermal.
Nangona kunjalo, iibhetri ze-lithium azikhuselekanga kuzoukubanda{0}umonakalo wemozulu. Iiseli ze-lithium eziqhelekileyo ezihlawuliswa ngaphantsi kwe-0℃zihlupheka kwi-lithium plating: idiphozithi yensimbi ye-lithium kumphezulu we-anode enciphisa ngokusisigxina umthamo kwaye inokudala imingcipheko emfutshane yangaphakathi{2}}PMC/NIH). Oku kuthetha ukuba ibhetri ye-lithium yeforklift ngaphandle kokwakhelwa-ngaphakathi ebandayo{2}}inkqubo yokhuseleko lokutshaja inokuba yingozi ngakumbi kwisikhenkcisi kunebhetri{3}}yeasidi, hayi ngaphantsi. I-advanteji ye-lithium ibonakala kuphela xa ibhetri iquka i-BMS -elawulwayo ephantsi{6}}ukuvalwa kwentlawulo yobushushu kwaye, ngokufanelekileyo, inkqubo edibeneyo yokuzifudumeza{7}}.
Uthelekiso olubanzi lwezi khemistri zimbini kuzo zonke izicelo zeforklift, yethuUhlalutyo oluneenkcukacha lwelothe{0}}yeasidi ngokuchasene ne-lithium{1}}ibhetri yeforklift ye-ionigubungela uluhlu olupheleleyo lwentsebenzo, iindleko, kunye nomahluko wokusebenza.
Enye inqaku ledatha yemisebenzi engekakulungeli utyalo-mali olupheleleyo lwe-lithium: I-Thin Plate Pure Lead (TPPL) iibhetri zimele ukhetho oluphakathi olunokumelana nokubanda okungcono kwaye akukho kugcinwa kwamanzi. Kodwa ubomi babo bomjikelo we-800-1,200 imijikelezo isawela kakuhle kwi-lithium. Kuyo nayiphi na indawo esebenza ngaphantsi -yeqondo le-10 ngaphezulu kwesiqingatha seeyure zokusebenza zemihla ngemihla, i-TPPL sisisombululo esilibazisekileyo seendleko-, asiyondleko{9}}engenye esebenzayo. Uya kuhlawula ngaphezulu kwe-lead-asidi ngaphambili kwaye usajongene nokutshintshwa kwiminyaka emi-3.
Indawo ebandayo yokuFundisa ibhetri yeForklift: Njani iBMS kunye nesiqu sakho{0}}Iinkqubo zokuZifudumeza ziLungisa njani iSubn{1}}i-Zero Performance
Owona msebenzi ubalulekileyo ainkqubo yokulawula ibhetri yokugcina ebandayolusezantsi{0}}lokhuseleko lwentlawulo yobushushu. Xa ubushushu beseli buhla ngaphantsi kwe-0 degree, i-BMS kufuneka ithintele ukutshaja ngokupheleleyo. Ayintle le-ukuba{5}}nophawu. Lukhuselo oluphambili ngokuchasene ne-lithium plating, indlela yokuthotywa ebangela ilahleko yesakhono esingenakuguqulwa kwaye, kwiimeko ezigqithisileyo, iisekethe ezimfutshane zangaphakathi ezinokunyukela kwiziganeko ezishushu. Uphando lubonise ukuba emva kwemijikelo yokukhupha i-500 - kwi-- idigri ye-10 ngaphandle kolawulo olululo lwe-thermal, umthamo webhetri unokuhla ukuya kumanqanaba okwenza ipakethi ingabinamsebenzi ngorhwebo, kunye nohlalutyo lwasemva kokufa lubonisa idiphozithi ye-lithium yesinyithi kwi-anode.
Ukuzifudumeza-iindlela zokuzifudumeza{1}}ingxaki yokutshixa ngokufudumeza iiseli kubushushu bokusebenza obukhuselekileyo phambi kokuvumela umsinga wentlawulo ukuba uqukuqele. Eyona nto ixhaphakileyo yokuphunyezwa kweshishini, edla ngokubizwa ngokuba yindawo ebandayo yokugcina i-forklift heater ngabaqhubi, isebenzisa i-PTC (i-Positive Temperature Coefficient) iipleyiti zokufudumeza ezifakwe kwisiseko semodyuli yebhetri nganye. Ngokwemigangatho yebhetri ye-LFP yezoshishino, xa ubushushu bemodyuli yehla ngaphantsi kwe-5 degree, izinto ze-PTC zisebenza ngokuzenzekelayo, ukutsala amandla kwitshaja ukufudumeza iiseli de zifike malunga ne-25 degree, ifestile efanelekileyo yokwamkelwa kwentlawulo. Ubushushu bexesha -lobude buxhomekeke kubungakanani bepakethi kunye nobushushu be-ambient: ipakethe ye-400Ah kwindawo ye-20℃degree ifuna imizuzu engama-20-25, nangona umgangatho wokugquma kunye nepakethe yejometri ilitshintsha kakhulu eli nani.
Ukugcina ubushushu obuphezulu beseli ngokufudumeza okudityanisiweyo kuphucula amazinga okwamkelwa kwentlawulo malunga ne-18% xa kuthelekiswa neebhetri ezingafudunyezwanga kubushushu obufanayo be-ambient. Kumsebenzi wama-20-welori enezimbini-ezicwangcisiweyo kunye nemigangatho ye-8- yokutshaja iifestile zeyure, nto leyo iguqulela kuqikelelo lwemizuzu engama-25–30 egciniweyo ngomjikelo wentlawulo, ngokuqhelekileyo umda owenza iibhetri{9}}ezimbini{11}}nge-forklift nganye yokujikeleza umsebenzi endaweni yokufuna ibhetri yesithathu. Ukuphelisa isethi yebhetri yesithathu kuzo zonke iinqanawa kunokumela ukucutha inkunzi yemali emanani amathandathu.
Ngaphandle kokufudumeza, ulawulo olusebenzayo lwe-thermal yeebhetri ze-lithium forklift kwindawo yokugcina ebandayo ibandakanya ezininzi - ukufakwa kwe-layer, ngokuqhelekileyo i-PE (i-polyethylene) i-foam okanye izithintelo ezifanayo ze-thermal ezisongelwe kwimodyuli nganye, ukugcina ubushushu ngexesha lokusebenza kunye namaxesha okungasebenzi. Ukudibanisa ukufudumeza okusebenzayo kunye ne-passive insulation kuthetha ukuba ibhetri igcina ubushushu bangaphakathi obuzinzile nangona i-forklift ipakishwe kwindawo ye--30℃ngeeyure. Ngemvelaphi enzulu kwizisebenza njani iinkqubo zolawulo lwe-thermal kwizicelo zamandla ashukumisayo, Umbono wethu wobugcisa uquka imigaqo yoyilo kuzo zonke iikhemistri zebhetri.
Kukho ukufunyaniswa okuchaseneyo okuxabisa ukufunyaniswa kubaphathi bezithuthi zogcino olubandayo. Uphononongo olupapashwe kwi-International Journal of Energy Research lufumene ukuba kwi--10 degree, iibhetri ezikhutshwe kumazinga aphantsi (0.5C) ngokwenene zafumana ukuthotywa komthamo omkhulu kunabo bakhutshwa kumazinga aphezulu (2C) (Wiley). Umatshini unxulumene nomahluko ekubunjweni kwefilimu ye-SEI kunye ne-lithium deposition dynamics kwiindawo ezahlukeneyo zokuxinana kwangoku phantsi kweemeko ezibandayo. Intsingiselo esebenzayo: kwindawo engaphantsi -enothi, ukusebenza kufutshane ne-1C yokukhupha kunesiqhelo "ethambileyo" i-0.5C kusenokwenzeka ukuba ikhuselekile ixesha elide{5}}lempilo yebhetri. Sebenzisa iilog zomthamo we-BMS ukulandelela ukuxhathisa kwangaphakathi kuzo zonke iishifti. Ukunyuka kwe-15% kwiiveki ezimbini kubonisa ukuba lixesha lokuphonononga iprofayile yakho yokukhutshwa, hayi nje ukulungiswa kweshedyuli.

Inkcukacha enye eyahlula abathengi abanamava-kubathengi bokuqala: soloko ucela umboneleli ukuba abonelele ngedatha yokugcina umthamo kubushushu obusebenzayo beziko lakho, hayi kubushushu begumbi. Ibhetri elinganiswe kwi-400Ah kwi-25℃inokuhambisa i-340Ah kwi-20 degree, okanye inokuhambisa i-280Ah. Lo msantsa we-60Ah umisela ukuba iifolokhwe zakho zigqibezela ishifti epheleleyo okanye isitali phakathi. Ababoneleli abaninzi abayi kuvolontiya le datha ngaphandle kokuba ucele.
PhononongaUgcino olubandayo lwePolinovel{0}}lulungele izisombululo zebhetri yeforkliftyenziwe ngobuchwephesha bolawulo oluhlanganisiweyo lobushushu, i-BMS{0}}eyazilawulayo{1}}ukuzifudumeza, kunye nokhuseleko lwe-IP67 ukuze lusebenze ngokuthembekileyo kwisikhenkcisi nakwiindawo ezihlala efrijini.
Imibuzo ebuzwa qho
Umbuzo: Ngaba unokuhlawula ibhetri ye-lithium forklift ngaphakathi kwendawo yokugcina impahla ebandayo?
A: Hayi ngaphandle kwe-BMS{0}}elawulwayo{1}}inkqubo yokuzifudumeza. Ukutshaja okusemgangathweni kweeseli ze-lithium ezingaphantsi kwe-0℃kubangela i-lithium plating, iidiphozithi zetsimbi kwi-anode ezinciphisa ngokusisigxina umthamo. Iibhetri ezineeseli ezidityanisiweyo zokufudumeza ezifudumeleyo kumaqondo obushushu akhuselekileyo phambi kokuvumela intlawulo yangoku ukuba ihambe, ivumela{5}}ukutshaja kwindawo ebandayo.
Q: Bungakanani ubomi bebhetri yeforklift yesikhenkcisi xa kuthelekiswa nosetyenziso oluqhelekileyo?
A: I-Lead-ibhetri ze-asidi zilahlekelwa yi-25% umthamo kwi-0℃kwaye ukuya kuma-55% kwi- - i-20℃, kunye nobomi bomjikelo behla ukuya kuma-500-1,000 imijikelo (2-3 iminyaka). Iibhetri ze-LiFePO4 ezinolawulo lwe-thermal zilahlekelwa malunga ne-6-8% kwi-degree ye-0 kwaye zifezekise imijikelezo ye-2,500-4,500 (iminyaka emi-5-7), kodwa kuphela ngokukhuselwa okufanelekileyo kokutshaja okubandayo.
Umbuzo: Yintoni ebangela ukuxinwa kwebhetri ye-forklift kwindawo yokugcina ebandayo kwaye ukuthintela njani?
A: Iifom zecondensation xa iiforklifts zitshintsha phakathi kweendawo ezibandayo kunye ne-ambient yeqondo lobushushu. Ubumanzi buqokelelana kwiitheminali zebhetri, izihlanganisi, kunye neebhodi zeesekethe, okubangela ukubola kunye neesekethe ezimfutshane ezinokubakho. Uthintelo lufuna i-IP67-evaliweyo yebhetri evaliweyo, i-desiccants yangaphakathi, indawo ye-buffer phakathi kweendawo zokushisa, kunye neeprothokholi ezivumela i-aclimation phambi kokutshaja.
Q: Loluphi olona hlobo lwebhetri lulungileyo lwendawo yokugcina izikhenkcisi ezingama-25?
A: LiFePO4 ene-PTC ehlanganisiweyo-yokuzifudumeza, i-BMS ephantsi{2}}ukuvalwa kwentlawulo yobushushu, kunye ne-IP67 ebiyelweyo. Qinisekisa ukuba idatha yobomi bomjikelo yavavanywa kwiqondo lokushisa lokusebenza, kungekhona ubushushu begumbi, kwaye ukuba i-threshold encinci yi-2,000 imijikelezo kwiqondo lokushisa elisebenzayo kunye ne-Ngaphantsi okanye elingana ne-20% yomthamo we-fade.
Umbuzo: Kutheni isalathisi sebhetri yeforklift sibonisa intlawulo epheleleyo kodwa sife ngokukhawuleza kwindawo yokugcina ebandayo?
A: Amaqondo obushushu abandayo anyusa ufundo lwamandla ebhetri. Zombini igeyiji yeforklift kunye netshaja zifunde amandla ombane aphezulu kuneyona meko yentlawulo, ebangela ukupheliswa kwentlawulo kwangaphambi kwexesha kunye nokutshaja ngaphantsi okungapheliyo. Ubushushu - bubuyekezwe i-algorithms ye-BMS echanekileyo ngoku ngokunyenyisa izibalo ze-SOC ngokusekelwe kwiqondo lobushushu leseli.
Uthelekiso olubanzi lweenketho zebhetri ye-lithium forklift kubo bonke abavelisi kunye nokusetyenziswa, bona yethuisikhokelo sokuvavanya iibrendi zebhetri ze-lithium forklift.
