Iindleko zokwenyani zokufumana iBattery Lifespan engalunganga
Xa ipakethe ye-48V LFP kwiziko lokuhambisa i-3-shift ifa kwiinyanga ezili-18 ngaphambi komhla oqikelelweyo wokutshintshwa, iindleko zokutshintshwa ngokuthe ngqo yi-invoyisi yokuqala kuphela. Kukho ixesha lokuphumla elingacwangciswanga, ukuthengwa ngokukhawuleza ngexabiso leprimiyamu, kunye nombuzo osezantsi wokuba ingabaimodeli ye-TCO yezithuthiyakhiwe kwiingqikelelo ezinokukhuseleka okanye kumanani okuthengisa. Kwimininzi-yemisebenzi yeshift eqhuba 300+ iintsuku ngonyaka, ubalo olunye olungalunganga kubomi bebhetri yeforklift lunokuba yilahleko emihlanu- okanye amathandathu{4}}yamanani kubomi bezithuthi.
Ingxaki enzulu kukuba "ubomi" buthetha umhla omiselweyo wokuphelelwa. Enyanisweni, ibhetri ye-forklift yombane ihlala ixesha elingakanani ngumsebenzi wekhemistri, iimeko zokusebenza, kunye nemikhwa yokutshaja imihla ngemihla, zonke zisebenzisana ngaxeshanye. Ipakethe ekhokelayo-yepakethe yeasidi kunye ne-LFP ye-lithium ipakethe ehleli kumgangatho wogcino mnye iya kuguga ngamaxabiso ahlukeneyo, ngenxa yezizathu ezahlukeneyo zombane. Ishishini litshintshile ngokufanelekileyo: iibhetri ze-lithium -iion ngoku zibalelwa kuqikelelo lwe-40-50% yemarike yebhetri yeforklift yehlabathi ngengeniso, isuka phantsi kwe-20% kwiminyaka emihlanu eyadlulayo. Olo tshintsho lwaluqhutywa yi-TCO imathematika, hayi ukuthengisa (Umbutho welori yezoShishino). Kodwa ubomi obude obunokubakho abuthethi ngokuzenzekelayo ubude bokwenyani bokuphila. Umsantsa phakathi kwamanani edatha yedatha kunye neziphumo zecandelo kulapho uninzi lwemali luchithwa khona.
Eli nqaku liqhekeza izinto eziguquguqukayo ezithile ezimisela ubomi bebhetri ye-forklift kwiimeko zendawo yokugcina impahla, kungekhona iimeko zebhubhoratri, kwaye ibeka into efunekayo ukusondela kwi-10,000 okanye ngaphezulu kwemijikelezo yentlawulo nge-LiFePO4 iteknoloji.
Lead-Acid vs. Lithium{2}}Ion: Forklift Battery Lifespan ngamaNani
Ngaphambi kokungena kwizicwangciso zokuphucula, kuyanceda ukuseka isiseko. Amashishini amabini aphambili ebhetri kwimarike yeforklift namhlanje, isikhukula ilothe-iasidi kunye ne-lithium iron phosphate (LiFePO4/LFP), ikwizikhundla ezahlukileyo kakhulu kubomi bokuphila.
| Ipharamitha | Ilothe ekhukulayo{0}}iAcid | LiFePO4 (LFP) Lithium |
|---|---|---|
| Ubomi bomjikelo oqhelekileyo (ukuya kwi-80% yokugcina umthamo) | 1,000–1,500 imijikelo | 3,000–6,{3}} imijikelo |
| Ubomi bekhalenda (iminyaka, -umsebenzi weshifu eyodwa) | 3-5 iminyaka | 8-15 iminyaka |
| Ubunzulu obucetyiweyo bokukhutshwa | I-50% (ukuhamba ngebhayisikile nzulu kukhawulezisa ukusuleleka) | I-80% (isakhiwo sekristale se-olivine esizinzile sinyamezela ukukhwela ibhayisekile enzulu) |
| Ixesha lokutshaja (umjikelo opheleleyo) | 8–10 iiyure + 6–8 iiyure zokuphola | Iiyure ezi-1-2, akukho pholisi efunekayo |
| Ifuthe lokutshaja ithuba | Yehlisa ixesha lokuphila 10-20% | Impembelelo encinci; inokwandisa ubalo lomjikelo ngokunciphisa umndilili weDOD |
| Iimfuno zesondlo | Ukunkcenkceshela yonke imijikelo ye-5-10, iintlawulo zokulinganisa, ukucocwa kwe-asidi | Ulungiso olululo{0} lwasimahla (BMS{1}}ilawulwa) |
La ngamanani -emvumelwano, hayi amanani entengiso. Eyona ntoUbomi bebhetri ye-forklift ye-lithium vs i-asidi ekhokelayokuwo nawuphi na umsebenzi othile kuya kuxhomekeka kakhulu kwizinto ezixoxwe kwicandelo elilandelayo. Kodwa umsantsa wolwakhiwo yinyani: Isakhiwo se-olivine se-olivine se-LFP sixhathisa ngokwendalo ngakumbi kwiindlela zokuwohloka, ngakumbi ukukhula kwe-SEI kunye nelahleko ye-lithium esebenzayo, enciphisa ilothe{1}}yeasidi kunye nezinye iikhemistri ze-lithium ezifana ne-NMC.
I-nuance enye ekufanele ifakwe kwiflegi: ayizizo zonke iibhetri ze-lithium forklift eziyi-LFP. Ezinye -iipakethi zexabiso eliphantsi zisebenzisa i-NMC (nickel manganese cobalt) iiseli, ezibonelela ngamandla aphezulu oxinaniso kodwa ubomi bomjikelo obufutshane kakhulu, ngokwesiqhelo 1,500–2,500 imijikelo phantsi kweemeko ezithelekisekayo. Ukubanjiswa kukuba i-NMC-ukuya{8}}utshintsho lwe-LFP alusoloko luthe tye. Iiprofayile zevoltage, iiprothokholi zonxibelelwano lwe-BMS, kunye nemeko yesimo somzimba ziyahluka, yiyo loo nto iiprojekthi ze-retrofit zifuna ipakethe{10}}inqanaba lobunjineli kunokutshintshana kweeseli. Ukuba umthengisi ucaphula "i-lithium-iyoni" ngaphandle kokuchaza i-cathode chemistry, lo mahluko ubaluleke kakhulu{13}}ixesha elide elilindelweyo kwibhetri yeforklift.
Izinto ezintlanu ezichaza ukuba ibhetri yeForklift ithatha ixesha elingakanani
Amanqaku obomi bomjikelo kwiinkcukacha zedatha alinganiswa phantsi kweemeko zelabhoratri ezilawulwayo: iqondo lobushushu le-25℃ambient, i-1C yentlawulo/inqanaba lokukhutshwa, kunye ne-80% yobunzulu bokukhutshwa. Oovimba bokwenyani bophula ubuncinci ezimbini kwezo meko mihla le. Nazi izinto ezintlanu eziguquguqukayo ezibonisa kakhulu ukuba umjikelo wakho weforklift wobomi bebhetri usebenza, ubekwe ngokwempembelelo.
Ubunzulu bokukhutshwa yeyona nto inkulu yelever.
Ipesenti nganye yenqaku le-DOD ibalulekile. Phantsi kweemeko zovavanyo oluqhelekileyo (25℃, 0.5C rate), iseli ye-LFP ekhutshelwe kwi-100% ye-DOD kumjikelo ngamnye iya kuzisa malunga nemijikelo ye-2,500-3,000 ukuya kwi-80% yokugcina umthamo. Nciphisa oko kukhutshwa kwi-80% ye-DOD, ukushiya i-20% kwindawo yokugcina, kwaye ubomi bomjikelezo bunokwelula ukuya kwi-5,000 okanye ngaphezulu. Yehla ukuya kwi-50% ye-DOD kwaye abanye abavelisi baxela ubomi obusebenzisekayo obudlula imijikelo ye-8,000 (Journal of Power Sources). Ulwalamano alukho mgca; i-20% yokuqala yokunciphisa i-DOD inikezela ngeenzuzo ezinkulu ngokungenakulinganiswa.
Enyanisweni, abaqhubi bezindlu zokugcina impahla abafane bakhuphe ubunzulu obufanayo. NgoMvulo unokubona i-85% ye-DOD ngosuku lokuthutha olunzima, ngelixa uLwesibini ubetha kuphela i-40%. I-BMS ibhala umjikelo ngamnye, kodwa uxinzelelo olongezelekayo luxhomekeke kulwabiwo. Ukucwangcisa ngononophelo, bonisa umndilili we-DOD yenqanawa yakho kuma-70–75%. Oku kubonisa okuqhelekileyo{8}}iipateni zeshifti zendlu yokugcina kwaye kunika umjikelo wobomi obukhuseleke ngakumbi kunokusebenzisa amanani osuku oluphezulu{9}lokukhupha.
Izinga lokutshaja kunye neqhinga lidala eyesibini{0}impembelelo enkulu kubomi bebhetri yeforklift.
I-C ephezulu - yokutshaja isantya (ngaphezulu kwe-1C) ivelisa ukushisa kwangaphakathi, ikhawuleza ukuchithwa kwe-electrode, kunye nokwandisa uxinzelelo lomatshini kwisakhiwo seseli. Ukutshaja nge-0.3C–0.5C kuthambile kakhulu, kodwa zimbalwa izinto ezenziwayo kwindawo yokugcina izinto ezinobunewunewu beefestile zokutshaja iiyure ezi-4. Indawo eswiti esebenzayo uninzi lweepakethi ze-forklift ye-LFP yi-0.5C-0.7C, ekhupha intlawulo epheleleyo malunga neeyure ezi-2 ngelixa igcina uxinzelelo lwe-thermal lulawuleka.
Ithuba lokutshaja, izithuba ezimfutshane{0}ngexesha lekhefu kunokukhupha ngokupheleleyo{1}}kunye{2}}nemijikelo yokutshaja kwakhona, kulapho i-lithium yahlukana khona kwi-asidi yelothe-. Kwibhetri{{2}yeasidi ekhokelayo, ukutshaja kwamathuba kuphazamisa umjikelo ofunekayo we-wokutshaja/wokuphola kwaye kunokunciphisa ubomi nge-10-20%. Kwi-LFP, okwahlukileyo kuyinyaniso. Ngenxa yokuba iiseli ze-lithium azinampembelelo yememori kwaye imijikelo eyinxenye ibala ngokulinganayo, ukunyuka ukusuka kwi-40% ukuya kwi-80% ngexesha lekhefu lesidlo sasemini kunciphisa i-DOD ephakathi kumjikelo ngamnye, owandisa ubalo lomjikelo opheleleyo. Imisebenzi eqhuba ezininzi{11}}iishedyuli zeshifti kunye nokutshaja kwamathuba rhoqo ukubona amanani angcono ebhetri yeforklift kunalawo anyanzela ukukhutshwa okupheleleyo{12}ukutshaja imijikelo kanye ngemini.
Kwezi zinto zintlanu, iqondo lobushushu lelona ntsebenzo lingajongelwa phantsi de kubekho into engahambi kakuhle.
Iiseli ze-LFP zisebenza kakuhle phakathi kwe-15℃kunye ne-35℃(59℃F-95℃F). Ngaphezulu kwe-40 idigri, ukuguga kwekhalenda, ukuthotywa okwenzekayo kungakhathaliseki ukuba ibhayisekile, kukhawuleza ngokumalunga ne-2-3x xa kuthelekiswa nobushushu begumbi. Ngaphantsi kwe-0 degree, eyona ngozi iyatshaja: i-lithium plating ingenzeka xa iiseli zihlawuliswa phantsi{10}}zero iimeko ngaphandle kokufudumeza{11}}kwangaphambili, okubangela ilahleko yesakhono esingenakubuyiseka nto leyo enokuthi ingabikho kwakhona i-algorithm ye-BMS (Journal of The Electrochemical Society).
Iindawo zokugcina iimpahla ezibandayokufuneka ingqalelo ekhethekileyo apha. Kwi-20℃, i-lead-ukusebenza kwebhetri yeasidi inokuhla ukuya kuma-45%. Ixabiso le-LFP lingcono kakhulu. Imithombo yoshishino oluninzi kunye neyethu imilinganiselo yentsimi kwiindawo ezibandayo{6} zokusasazwa kwekhonkco zibonisa malunga ne-80-90% yomthamo wokukhutshelwa olinganisiweyo ogcinwe kwi--20 degree. Kodwa ukutshaja kuloo ndawo ngaphandle kwesifudumezi esidibeneyo sebhetri kulapho ukuthotywa kwebhetri yeforklift kubangela ukuba kube nzima. Iipakethi ze-LFP ezibandayo zanamhlanje{12}}zisombulula oku ngezinto zokufudumeza ze-PTC ezifudumeza iiseli kubushushu obukhuselekileyo bokutshaja phambi kokuba uqukuqelele ngoku. Ukuba uvavanya iipakethi zemeko-bume yesikhenkcezisi kwaye iphepha leenkcukacha aliyikhankanyi inkqubo ehlanganisiweyo yokufudumeza, ayisosikhewu esisisithuba - yingozi kubomi bolwakhiwo.
Iseli-ukuya{1}ukuhambelana kweseli ngaphakathi kwebhetri ipakethi yinto yesine, kwaye leyo phantse akukho mntu ukhuphisanayo exoxa ngayo.
Ipakethi yebhetri yeforklift iqulethe iiseli ezininzi okanye amakhulu eentambo ezifakwe kuthotho. Ubomi bomjikelo wepakethi bubonke buthintelwe yeyona seli ibuthathaka. Ukuba iseli enye inokumelana okuphezulu kwangaphakathi okanye umthamo ophantsi kunabamelwane bayo, i-BMS kufuneka isoloko iguqula amandla ukuze igcine iiseli zilungelelene, kwaye loo seli ibuthathaka iya kuthotywa ngokukhawuleza, ihlise imeko yempilo yonke yepakethi.
Kwinqanaba lokuvelisa, lo ngumbuzo wokuhlelwa kweeseli kunye nokudibanisa. Abavelisi beebhetri zePremium bahlela iiseli ukuba zibe ngaphakathi kwe-2-3% umthamo kunye nokunyamezela kwangaphakathi ukunyamezela ngaphambi kokuhlanganisa ipakethe. Abavelisi bexabiso eliphantsi{4}banokwamkela unyamezelo lwe-10-15% okanye ngaphezulu, oko konga kwiindleko zemveliso kodwa yenze ikloko yokuphawula: ngaphakathi kwemijikelo eyi-1,000–2,000, ukungahambelani kuyakhula, kwaye eyona seli ibuthathaka iba ngumqobo. Esi sesinye sezizathu eziphambili zokuba kutheni iipakethi ezimbini ze-LFP ziyafana, umthamo ofanayo, ikhemistri efanayo, umlinganiselo ofanayo womjikelo, unokwahlukana ngokumangalisayo kwinene{12}}ukuqina kwehlabathi.
Ukungcangcazela kunye noxinzelelo lomatshini ukujikeleza ezintlanu eziphezulu.
Iiforklift zivelisa ukungcangcazela okungaphezulu kunezithuthi zabakhweli okanye iinkqubo zokugcina ezimileyo. Ngaphezulu kwamawaka eeyure zokusebenza, olo xinzelelo lomatshini ludinwa imivalo yebhasi edityanisiweyo, ikhulule uqhagamshelo lwebholithi, kwaye inokubangela i-BMS sensor drift. Akukho nanye kwezi ntsilelo ezibonakalisayo kuvavanyo lomjikelo welebhu, kodwa zingunobangela oqhelekileyo wokungaphumeleli kwepakethi yangaphambi kwexesha entsimini. Ulwakhiwo lwepakethi eyomeleleyo - edityanisiweyo (engaculwanga) uqhakamshelwano, ukungcangcazela{4}}i-BMS ethotyiweyo enyukayo, kunye ne-IP65+ yokukala kwendawo evalekileyo - iyimfuneko kubomi bebhetri yeforklift kwimininzi{7}}yemisebenzi yeshift.
Eyona nto ifunekayo ukuze ubethe ii-Cycles eziyi-10,000
Eli candelo kulapho siphuma khona kwindawo yesikhokhelo segeneric siye kwidatha yobunjineli yePolinovel.
I "10,{1}} umjikelo" ibango elivela kwezinye LFP forklift zedatha yebhetri yinyani, phantsi kweemeko ezithile. Ezo meko zezi: I-DOD ibanjwe okanye ngaphantsi kwe-80%, itshaja ku-0.3C–0.5C, ubushushu be-ambient bugcinwe phakathi kwe-20℃kunye ne-30℃, kunye neseli{8}}ukuya{9}}ukuhambelana kweseli ngaphakathi kwe-3% kwindibano yepakethi. Ngaphantsi kwezo parameters, i-olivine crystal structure ye-LFP izinzile ngokwenyani ngokwaneleyo ukuze igcine i-80% umthamo odlulileyo we-10,000 opheleleyo{15}}kwimijikelo elinganayo. Uphando olupapashwe kwiIjenali yemithombo yamandlaiqinisekisile ukuba ukuthotywa kwe-LFP cathode kuqhubeka ngokucotha kakhulu xa kusebenza ngaphakathi kule mvulophu.
Kodwa umsantsa phakathi kwemvulophu yovavanyo kunye nendawo yokugcina impahla kulapho abavelisi abanyanisekileyo bazahlulayo kwintengiso-abakhuphisana abaqhutywayo. I-3{4}}iziko lokuhambisa ishift ePhoenix, apho amaqondo obushushu endlu yokugcina impahla ehlotyeni adlula ama-40 degrees , ayizukubona umjikelo ofanayo wokubala njengeqondo lobushushu{6}}lendawo yoxubo elawulwayo e-Netherlands. Umsebenzi obandayo-wetsheyini eMinnesota obiza iibhetri ngaphakathi kwe--15℃freezer ngaphandle kobuchwepheshe bokufudumeza kwangaphambili uyakubona i-lithium plating kunyaka wokuqala.
Kuvavanyo lwethu lwangaphakathi kuzo zonke iipakethe ze-LFP ezininzi zokucwangcisa, iipakethi ezakhiwe Ngaphantsi okanye zilingana ne-3% yeseli{1}}ukuya{2}}ukunyamezela iseli kubonise malunga ne-1.5x ukuya kwi-2x ukubala komjikelo ngaphambi kokufikelela kwi-80% ye-SOH xa kuthelekiswa neepakethi ezakhiwe Ngaphantsi okanye ezilingana ne-12% yokunyamezela, phantsi kweemeko ze-D05 ze-D5, ngenye indlela i-D05. izinga lentlawulo). Iseti yedatha epheleleyo iyafumaneka kwabo baza kuba ngabathengi ngesicelo. Ubukhulu besikhewu yeyona nto ibalulekileyo xa kucwangciswa: ukuhambelana kweeseli ayisiyonto "emnandi ukuba nayo" yomgangatho. Sisigqibo solwakhiwo sokuba ingaba ipakethi yakho ifikelela kwimijikelo engama-4,000 okanye engama-8,000.
Kukwakho noguquko oluphantse lungabikho-zidilesi zesiqulatho esijongene noluntu:Umgangatho we-algorithm ye-BMS. Inkqubo yokulawula ibhetri ayigcini nje ukubeka iliso. Ithatha{2}}izigqibo zexesha lokwenyani malunga nentlawulo yokunqunyulwa kwamandla ombane, ubuchule bokulinganisa iiseli, ukuncitshiswa kwe-thermal, kunye nolawulo lwefestile ye-SOC. Iipakethi ezimbini ezineeseli ezifanayo kodwa i-firmware ye-BMS eyahlukileyo inokwahluka nge-20% okanye ngaphezulu kubomi bexesha elide{5} lomjikelo, ngokusekwe kuvavanyo lwethu lokuthelekisa kulo lonke ulungelelwaniso lwe-BMS. Ezinye izicwangciso ze-BMS zibeka phambili ubukhulu besakhono esisebenzisekayo kumjikelo ngamnye (othandwa ngabaqhubi, kuba ixesha lokuqhuba ngentlawulo nganye linyusiwe) ngeendleko zokuthotywa ngokukhawuleza. Abanye bancama i-5-10% yomthamo osebenzisekayo ngokunciphisa ifestile ye-SOC, eyandisa kakhulu ubomi bepakethi. Umqulu we-LFP{11}owenziwe kakuhle wokusetyenziswa kwendawo yokugcina kufuneka unyanzelise ifestile ye-SOC esebenzayo emalunga ne-10-90%, incama malunga ne-10% yomthamo we-nameplate ukutshintshiselana nobomi bomjikelo obandisiweyo. Ukuba umthengisi ubanga i-100% ye-SOC esebenzisekayo ngaphandle korhwebo lobomi bomjikelo, yiphathe njengeflegi ebomvu.
Ngeenjongo zokubonisa i-TCO: eyona -esebenza kakuhle, enye{1}} okanye kabini{2}}iindawo zokugcina ishifti ezinolawulo olufanelekileyo lobushushu ziya kufikelela ngokwenyani imijikelo eyi-4,000–5,000 ukusuka kwipakethi ye-LFP esemgangathweni phambi kokufikelela kwi-80% ye-SOH. Oko sele imele 3x–4x ukuphucuka ngaphezu ilothe -asidi. Imisebenzi elawula ngokungqongqo i-DOD, ukusebenzisa ithuba lokutshaja, kunye notyalo-mali kwipakethi engqamene ngokuqinileyo inokutyhala ubomi bebhetri yeforklift ukuya ku-6,000–8,{16}} kuluhlu lomjikelo. Kwizixhobo ezinobushushu obugqithisileyo okanye{18}}izithintelo zomjikelo, ezifana ne-3{20}}shift eqhubekayo, imimandla ebandayo{27}}yekhonkco, okanye amaqondo obushushu azinzileyo angaphezu kwama-35 degree, musa ukumodareyitha kwi-10,000. Uhlahlo lwabiwo-mali kwi-4,000, qinisekisa ngedatha yendawo, kwaye ulungelelanise ukuya phezulu ukuba iimeko ziyavuma. Ukuba ufuna uqikelelo lomjikelo wobomi obukhethekileyo kwisiza kwimodeli ye-TCO, iqela lethu lobunjineli lesicelo linokuqhuba uhlalutyo ngokuchasene nemilinganiselo yokusebenza yeziko lakho.
Iimpazamo eziqhelekileyo ezibulala ibhetri yeForklift Kwangethuba
Emva kokugunyazisa kunye nokubonelela ngeenkonzo ze-LFP iipakethi zeforklift kwiindawo ezininzi zokugcina iimpahla, iipatheni ezithile zokusilela ziphinda ziphinde zibuyekezwe rhoqo. Ezi ayizongozi zethiyori. Ziyimpazamo ezithile ezinciphisa ubomi bebhetri ye-forklift kwintsimi.
Ukutshaja kwindawo engaphantsi{0}}enothi ngaphandle kokhuseleko lobushushu.
Olu lolona qheliselo lutshabalalisayo esidibana nalo kwimisebenzi ebandayo{{0}yekhonkco. Xa iseli ye-LFP ihlawuliswa ngaphantsi kwe-degree ye-0, i-lithium ion plate kwi-anode surface endaweni yokudibanisa kwisakhiwo segraphite. Le plating ye-lithium ayinakuguqulwa. Inciphisa ngokusisigxina umthamo, inyuse ukuxhathisa kwangaphakathi, kwaye kwiimeko ezimandundu kunokudala umngcipheko wangaphakathi omfutshane{5} wesekethe.
Sizibonile iipakethi ezithelekelwe isi-4, 000+ imijikelo iphulukana ne-35% yomthamo wazo kwimijikelo engama-800 kuba abaqhubi bebeplaga iitshaja kwiibhetri ezihleli ngaphakathi kwe--10℃freezer bay. Ukulungiswa kuthe ngqo: sebenzisa iipakethi ezinezifudumezi ezidibeneyo ze-PTC ezifudumala iiseli ubuncinane kwi-degree ye-5 ngaphambi kokwamkela intlawulo yangoku, kunye ne-BMS evimbela ukutshaja ngaphantsi komda okhuselekileyo. Ukulungiswa kufuneka kuyilwe kwinqanaba lokupakisha. Ukubuyisela ukhuseleko lwe-thermal emva kokuthunyelwa kunqabile ukuba kwenzeke. Xa uselungelweni lokupakisha{10}}itsheyini ye-LFP ebandayo, cela umthengisi ukuba abonise umda wokuvala intlawulo ye-BMS kumaxwebhu ovavanyo, hayi nje ukubanga ukuba ukhona.
Ukukhutshwa okunzulu okuqhelekileyo ngaphantsi kwe-10% ye-SOC.
Abanye abaqhubi baqhuba iiforklift de umatshini uzivale, nto leyo eyenzeka kwi-5% SOC okanye ngaphantsi. Kobu bunzulu bugqithisileyo, iiseli zomntu ngamnye zinokubuya umva-ipolarity, ibangele ukunyibilika kobhedu ukusuka kumqokeleli wangoku we-anode ofaka kwisahluli kwaye yenze iimfutshane{3}}ezimfutshane. Iseli enye ngaphezulu{5}}ekhutshiweyo kwi-16-seselfowuni yothotho ingacutha umthamo osebenzisekayo wepakethi ngama-25–30%. Umgaqo ochanekileyo: ukutshaja kwakhona xa isalathisi se-SOC sibetha i-20%. Kumaziko apho abaqhubi behlala bengayihoyi le nto, i-BMS enenyanzeliso esezantsi{15}}ye-voltage cutoff kwi-10% SOC kuphela kokhuseleko oluthembekileyo. Ngexesha lokuthengwa kwempahla, qinisekisa ukuba i-BMS inyanzelisa le cutoff njengokhuseleko lwenqanaba le-hardware, kungekhona nje isilumkiso sesofthiwe esinokuthi abaqhubi baphumelele.
Ukusebenzisa iitshaja{0} zeasidi kwiipakethi ze-lithium.
Oku kwenzeka rhoqo kunokuba nawuphi na umphathi wesixhobo afuna ukukuvuma, ngakumbi ngexesha lotshintsho xa inqanawa ifuduka ukusuka kwilothe-iasidi ukuya kwi-lithium. Itshaja ze-Lead-ze-asidi zisebenzisa i-multi-iprofayili yenqanaba elinesigaba sokulinganisa sokugqibela kumbane ophakanyisiweyo, ngokuqhelekileyo i-2.7-2.8V ngeseli nganye kwisiseko se-2V se-nominal, etyhala kakuhle ngaphezu kwe-voltage yokuphelisa intlawulo ekhuselekileyo yeeseli ze-LFP (3.65V ngeseli). Ukutshaja okungapheliyo ukusuka kwiprofayili engahambelaniyo kukhawulezisa ukubola kwe-electrolyte kwaye kunokutyhala iiseli kwiindawo zoxinzelelo lwe-thermal. Soloko uqinisekisa ukuhambelana kwetshaja, kwaye ngokufanelekileyo sebenzisa itshaja nge-CAN{10}}unxibelelwano lwebhasi oluxhawula isandla ngqo ne-BMS ukunyanzelisa i-CC{11}}ijiko lokutshaja elichanekileyo.
Ukungahoyi imeko yokubeka iliso kwimpilo.
Uninzi lweepakethi ze-LFP ezinamaqonga e-BMS anamhlanje angena kwidatha ye-SOH ngokuqhubekayo: ukuphelelwa amandla, ukuchasana kwangaphakathi, iimethrikhi zokungalingani kweeseli. Le datha ikhona. Kodwa kwinani elimangalisayo lemisebenzi, akukho mntu uyijongayo de ibhetri isilele ngokuthe ngqo. Ukubeka iliso okusebenzayo kwe-SOH kukuvumela ukuba ubambe iimpawu zokuqala zokuthotywa kwebhetri ye-forklift, iseli enye ekhukulisekayo ngaphandle kwebhalansi, isantya sokuhla samandla esidlula iigophe eziqhelekileyo zokuguga, ngaphambi kokuba zingene kwipakethi yokusilela. Uphononongo lwe-SOH lwekota luncinci; ngenyanga ingcono{4}kumsebenzi womjikelo ophezulu. Xa uvavanya ababoneleli ngebhetri, buza ukuba ingaba i-BMS yabo iyayixhasa na i-SOH yokuthunyelwa kwedatha ekude okanye ifuna isixhobo sokuxilonga kwindawo-. Umahluko umisela ukuba uyakwazi ukubeka iliso kwisikhululo{8}}sempilo yebhetri ebanzi ukusuka kwideshibhodi okanye ufuna igcisa kuwo wonke umatshini.
Uluhlu lwakho loBomi bebhetri yeForklift: Yonke imihla, ngeNyanga, nangoNyaka
