Yintoni Ulawulo Lwenkqubo Yebhetri?
Umbuzo uvela kakhulu kumaqela okuthenga ngokuthelekisa amaxabiso. Baza kujonga iipakethe ezimbini ze-48V 400Ah, babone iiseli ezifanayo ezidweliswe kuwo omabini amaphepha, kwaye babuze ukuba kutheni enye ixabisa i-30% ngaphezulu. Impendulo isoloko ikwinkqubo yolawulo. Kodwa oko kuthengisa nzima kuba awukwazi ukufota i-algorithm yokulawula.
Ulawulo lwesixokelelwano sebhetri yingqiqo elungelelanisa indlela ipakethi esebenza ngayo-xa ivumela ukutshaja, ilandelelana njani abafowunelwa, nokuba ibhalansisa iiseli, iphendula njani kubushushu. Iiseli zizinto ezithengiswayo kweli nqanaba. I-CATL, EVE, CALB{3}zonke zenza iiseli ze-LFP ezifanelekileyo. Yintoni emisela ukuba ipakethe ithatha imijikelo engama-3000 okanye imijikelo eyi-1500 phantsi kokusetyenziswa okufanayo ikakhulu iphantsi kwindlela ezo seli ziphathwa ngayo.
Eyona nto ingahambi kakuhle
Nantsi into esabothusa abantu. Iiseli zeLithium azinakuhlawuliswa ngaphantsi kwe-0 degree. Akufunekanga "ingabi"{3}}ayinakwenzeka, ngaphandle komonakalo. Kwenzeka ntoni ukuba ii-ion ze-lithium azikwazi ukungena ngokufanelekileyo kwi-anode yegraphite xa kubanda. Endaweni yoko batyabeka njenge-lithium yentsimbi kumphezulu. Oku kusisigxina. Iseli ibonakala ilungile, ihlawulisa kakuhle, isebenza kakuhle iinyanga. Emva koko ufumana i-fade yomthamo okhawulezayo, kwaye ekugqibeleni iifutshane zangaphakathi ukusuka ekukhuleni kwe-dendrite.
IYunivesithi yeBattery ibhalwe kule minyaka idlulileyo. Uvavanyo lwabo lubonisa ukuba neeseli ezihlawuliswa kwi--10℃kunye nokunciphisa okwangoku zisabonisa i-lithium plating phantsi kwe-microscope. Umonakalo uqokelelene kwaye ungabonakali de ungabikho.
Ke iBMS kufuneka inyanzelise umda wobushushu. Ukuba uqhuba iiforklift kwindawo yokugcina ebandayo okanye iiyadi zangaphandle ebusika, ipakethe kufuneka yale intlawulo engaphantsi komqobo. Hayi nje ukulumkisa{2}}kwala ngokwenene. Sibeka ezethu kwi--10℃cutoff yokutshaja, ngokuncitshiswa okwangoku phakathi kwe--10℃kunye ne-0 degree. Ezinye iinkqubo ezinexabiso eliphantsi azinalo kwaphela olu khuseleko.
Ukugcinwa okubandayo kunye nokuhanjiswa kwempahla ekhenkcezisiweyo zezona zimbi kakhulu kule nto. Iipakethi ezingenayo neziphumayo kwiindawo zesikhenkcisi, zitshaja kwiidokhi zokulayisha ezingafudunyezwanga. Abasebenzi abayicingi loo nto kuba ilothe -iasidi ayinamda.
Umba{0}wangaphambili wentlawulo wahlukile kodwa uhlobene{1}}imalunga nolandelelwano lwe-contactor kuneqondo lobushushu, kodwa yenye into etsitywayo ukonga ixabiso. Xa uvala abafowunelwa ukudibanisa ipakethi yebhetri kumthwalo, kukho umzuzwana apho yonke i-capacitance kwicala lomthwalo kufuneka ihlawule phezulu. Ukuba ubethelela ipakethe yombane egcweleyo kwii-capacitors ezikhutshiweyo, ufumana i-spikes yangoku ngaphezulu kwe-1000A kwiimillisecond ezimbalwa. Kwanele ukuwelda iingcebiso zoqhagamshelwano kunye.
I-contactor ene-welds ivaliwe ayikwazi ukukhupha ipakethi ngexesha lempazamo. Okuthetha ukuba ukhuseleko oludlulayo luyayeka ukusebenza.
Isisombululo sithe ngqo{{0}vala i-negative engundoqo kuqala, emva koko yondla ngoku nge-pre{1}}isixhasi sokutshaja, jonga de amandla ombane afike malunga ne-95% yombane wepakethi enomgangatho ozinzile, emva koko uvale i-positive ephambili. Ithatha imizuzwana emi-2-3. Abanye abahlanganisi bayayitsiba ukugcina ixesha lokuqalisa. Isebenza kakuhle de ingasebenzi.
ICandelo Lokulungelelanisa
Iyandidika lento kuba ilungiseka. Ungathenga A-iiseli zebakala kumenzi webhetri weLiFePO4 othembekileyo, uzihlanganise kakuhle, kwaye usenayo ipakethe ephakathi kuba ulungelelwaniso alukho.
Umba kukunyamezela imveliso. Iiseli ezisuka kwibhetshi enye yemveliso ziyahluka ngokomthamo nge-1-3%. Yinyani leyo. Kuluhlu, oyena usezantsi{5}}umthamo weseli umda wokukhutshelwa (ibetha ingenanto kuqala) kunye nenani eliphezulu lomda weseli intlawulo (ibethe igcwele kuqala). Ngaphandle kokulungelelanisa, usebenzisa mhlawumbi i-90% yomthamo wepakethi yokwenyani. Kwaye loo seli ibuthathaka iba noxinzelelo ngakumbi kumjikelo ngamnye, iguga ngokukhawuleza, iba buthathaka. I-Positive feedback loop.
I-bancing engenziyo yopha ngaphandle kwentlawulo egqithileyo ngezixhasi. 50-100maA ngokwesiqhelo. Ukuba iseli yi-50mAh ngaphambi kwezinye, yiyure yokulungisa. Ilungile ukutshaja ngobusuku. Kodwa izixhobo zokuphatha izinto azihlawulisi ubusuku bonke{5}}uyakuhlawulisa ithuba ngexesha lekhefu, qhuba iishifti ezininzi, gcina iilori zihamba. I-Pasisive balancing ayikwazi ukuqhubeka.
Ulungelelwaniso olusebenzayo luhambisa amandla phakathi kweeseli. Imisinga ephezulu, akukho mandla achithwayo. Iipakethi zethu ziqhuba ukulinganisa okusebenzayo kwi-1A + kuba izicelo ziyayifuna.
Ingqiqo ilandelela i-avareji yamandla ombane kuzo zonke iiseli{0}ukuya kwi-160 kwiipakethe ezinkulu{2}}kunye neeseli zeflegi ezitenxileyo. Ukulinganisa kusebenza ngaphezulu kwe-3.7V ye-voltage ye-cell cell, ngexesha lokutshaja, xa kungekho mpazamo iiflegi zikhona. Xa iseli ingena ngaphakathi kwe-10mV yomndilili, iyaphuma kumgca wokumanisa.
Umahluko uvela -ekugcineni umthamo wexesha elide. Iipakethi ezinolungelelwaniso olusebenzayo zihlala ngaphakathi kwe-20mV yeseli-ukuya{4}}umahluko weseli kumawaka emijikelo. Iipakethi ngaphandle kwayo zikhukuliseka ziye kwi-100mV+ umahluko phakathi konyaka, okuthetha ukunciphisa kakhulu umthamo osebenzisekayo.
Impendulo yeThermal
Wonke umntu uyazi malunga -nobushushu obuphezulu bokucutha isilumkiso-55℃degree, 60℃shutdown. Inxalenye eluncedo ngakumbi yindlela ophendula ngayo ngaphandle kokubulala nje izixhobo.
I-forklift phakathi kwendawo yokugcina impahla enomthwalo kwiifolokhwe ayifanele ivale nje ngenxa yokuba ubushushu bubetha umgubasi. Oko kuyingozi. Into oyifunayo kukuthoba okuqhubelekayo-ukunciphisa imida yangoku njengoko ubushushu bunyuka, vumela umsebenzi agqibezele umsebenzi okhawulezileyo ngamandla acuthiweyo, emva koko unyanzelise{{3}ixesha elipholileyo lokuhla.

I-monitor yethu ye-thermal logic ijonga amanqaku amaninzi kwimodyuli nganye ngenxa yokuba ii-gradients zeqondo lokushisa ngaphakathi kwepakethi zinokubetha i-15℃phantsi komthwalo onzima. Inzwa enye yayo yonke ipakethe ayikuxeleli nto iluncedo. Ukuba imodyuli enye ihlala iqhuba i-10℃hot kunezinye, lonto iqhele ukunyusa uxhathiso lwangaphakathi kwezo seli{4}}isilumkiso sakwangoko sengxaki ekhulayo. Thina iflegi umahluko ngaphezu 10℃for uphando.
Imibundu yokuphendula ilayitiwe: ngaphezu kwe-45 degree, ukunciphisa intlawulo yangoku. Ngaphezulu kwe-55 idigri, isilumkiso kunye nokwehla kokukhutshwa. Ngaphezulu kwe-60℃, ulandelelwano olulawulwayo lokuvala. Ngaphezulu kwe-65 degree, ipakethe ephawulwe njengengaphumeleliyo ekulindeni ukuhlolwa. Inyathelo ngalinye linika ulwazi lomsebenzisi kunye neenketho kunokusika nje amandla.
Yintoni le Yehlayo
Xa sithetha nabathengi sithelekisa ababoneleli bepakethe yebhetri ye-lithium, incoko idla ngokuqala ngee-specs zeseli kunye nexabiso. Ilunge kakhulu. Kodwa ngaxa lithile kufuneka ubuze malunga nengqiqo yolawulo{2}}oluphi ubushushu obunqumlweyo, yeyiphi indlela yokulinganisa kweyiphi yangoku, yeyiphi{3}}eyangaphambili intlawulo yokulandelelana. Iimpendulo zikuxelela ukuba ujonge izisombululo ezenziwe ngobunjineli okanye ixabiso-iibhokisi ezicuthiweyo.
I-IEC 62619 igubungela iibhetri ze-lithium kwimizi-mveliso yeeforklift, ii-AGVs, olo hlobo lwento. Ifuna uhlalutyo olusebenzayo lokhuseleko. Kodwa iipakethi ezimbini zinokudlula zombini i-62619 kwaye zibe nolawulo oluhluke ngokupheleleyo. Umgangatho ngumgangatho, hayi isilingi.
Phofu. Iiseli zifumana yonke ingqalelo. Inkqubo yolawulo yenza uninzi lomsebenzi.
