Ngubani oyena Mboneleli weZisombululo zebhetri yeLithium?
Ndiye ndakhangela iibhetri zemizi-mveliso yezixhobo zokuphatha izinto ukususela ngo-2018. Uguqulelo lwezindlu ezintathu, iiretrofits ezimbini zokugcina ezibandayo, iprojekthi ye-GSE yesikhululo seenqwelomoya. Yonke iprojekthi iqale ngombuzo ofanayo okuzisa apha.
Akukho mthengisi "ongcono" omnye. Kodwa kukho ababoneleli abaya kutshabalalisa ukusebenza kwakho, kunye nababoneleli abaya kuzisa oko bakuthembisayo. Umahluko uyehla kwizinto ezininzi zeRFQ zokuthelekisa amaphepha aziphosakele ngokupheleleyo.
Ingxaki Akukho mntu Uthetha Ngayo kwiincwadana ezinemifanekiso
Kunyaka ophelileyo ndiye ndanceda iziko lokuhambisa eMidwest ukuba livavanye ukusilela kwebhetri. Baye batshintshela kwi-lithium kwiinyanga ezili-18 ngaphambili, bathenge kumthengisi onikezela ngamaxabiso angama-35% ngaphantsi kwe-avareji yemarike. Ixabiso lokuthengisa libandakanya "iBanga{4}}iiseli ze-CATL" kunye "newaranti yeminyaka emi-5."
Xa sivula iipakethi ezingaphumelelanga, iikhowudi ze-QR kwiiseli zazikhutshiwe. Okwenyani A{1}}iiseli zebakala ezisuka kubavelisi abafana neCATL, BYD, okanye EVE Energy zithwala iikhowudi ezilandelekayo eziqhagamshela umva kwidatha yebhetshi yemveliso. Xa ezo khowudi zisusiwe, oko kuthetha ukuba kukho umntu ongafuni ukuba wazi ibakala lokwenyani leseli. Sithumele iisampulu kwiqela{4}}lebhu lesithathu. Iiseli bezikuB-ibakala kokona kulungileyo, kunye nomthamo owahlukileyo ogqitha kwi-8% ngokuchasene nomgangatho webakala A-we-±2.5%.
Oku akwenziwanga yodwa. Kwi-Endless Sphere iforum ye-DIY, omnye umsebenzisi uxele ukuthenga ibhetri ye-48V 72Ah engakwaziyo ukuhambisa i-10Ah yokwenyani umthamo. Omnye uphawule ukuba umthengisi uvumile ukuba banyusa ubungakanani bomthamo ukuze baphumelele intengiso (engapheliyo-sphere.com/sphere/threads/beware{7}ye{8}}ye-ebike{9}}ifake{10}}umthamo{11}}kunye{12}}neziseli{13}2}285. Iforum yobuchwephesha beForkliftAction ibalisa amabali afanayo: amagcisa afumana iibhetri ze-lithium zisilela kakuhle ngaphambi kokuba zilinganiswe ubomi bomjikelo, phantse zisoloko zilandelelwa kumgangatho weseli, uqwalaselo lwe-BMS, okanye iindlela ezimfutshane zolawulo lwe-thermal.
Eyona nto ibalulekileyo xa uvavanya ababoneleli
Ukufumana iiseli kunye nokuhlelwa kwezinto elubala
Iiseli zePremium yeLiFePO4 zihamba ngenkqubo yokuhlela emva kokwenziwa. Inqanaba lokugquma i-electrode lifuna ukunyamezelwa kobunzima obungaphantsi kwe-2μm. Emva kovavanyo lokuqala, iiseli kufuneka ziphumle ubuncinane iintsuku ezili-15 phambi kokuhlelwa kokugqibela. Eli xesha lokuguga lijongene neziphene ezifihlakeleyo. Ababoneleli batsiba eli nyathelo leengxaki ngenqanawa ngqo kwindawo yakho yokugcina impahla.
A-iiseli zebakala ezisuka-kwimizi-mveliso yodidi lokuqala zibonisa amazinga aneziphene malunga ne-2%. Iifektri zenqanaba lesibini nelesithathu-ziqhuba 5-10%. Umahluko wamaxabiso phakathi kwamabanga ungabetha kuma-40%, nto leyo echaza ukuba kutheni abanye ababoneleli bephinda baleyibhile i-B-grade njengeprimiyamu.
Imibuzo emithathu yomthengisi onokubakho:
- Ngubani owenza iiseli zakho? (CATL, BYD, EVE Energy, CALB ngawona magama amakhulu)
- Ngaba ungandibonisa iingxelo zovavanyo lweseli kunye nokuqina kwamandla ombane kunye nedatha yokuthelekisa umthamo?

Ukuthingaza kuyo nayiphi na kwezi kukwenza ungafaneleki.
Ukudityaniswa kwe-BMS kwisixhobo sakho esithile
Inkqubo yoLawulo lwebhetri kulapho uninzi lweengxaki zokuhambelana zenzeka khona. Iiforklift zoshishino zisebenzisa i-CAN Bus yonxibelelwano protocol. I-BMS kufuneka ithethe ngokuchanekileyo kuzo zombini isilawuli seforklift kunye netshaja.
Kwi-Practical Machinist, omnye umsebenzisi wanika isilumkiso esifanele ukuphindaphinda: "i-BMS yangaphakathi imida yokukhupha ngoku kwixabiso elilinganisiweyo lebhetri. Ukuba i-forklift yakho ye-amperage draw idlula oko i-BMS ivumela, kwangomzuzwana, ibhetri iyacima." Uphinde wabonisa ukuba iibhetri ze-LFP zinobunzima obungaphantsi kwe-lead - yeasidi, echaphazela ibhalansi yobunzima. Eminye imisebenzi kufuneka yongeze iipleyiti zentsimbi okanye ukunciphisa ukulinganiswa komthwalo.
Kwizicelo ze-forklift ye-LiFePO4, qinisekisa ezi parameters ze-BMS: ngaphezulu{1}}ukhuseleko lwentlawulo kwi-3.65±0.05V kwiseli nganye (iflegi ebomvu ukuba ayichazwanga ngeseli nganye), umbane wokulinganisa kwi-3.6±0.05V ngeseli, intlawulo yokunciphisa iqondo lobushushu kwi-60 degree, i-low{7}}}iqondo lobushushu eliphantsi okanye iqondo lobushushu elingaphantsi kwe-5 ukuvalelwa kunye nokukhululwa kwi-degree℃5 150μA. Inethiwekhi ye-CAN ifuna i-120Ω izichasi zokuphelisa kuzo zombini iziphelo. Izinqamli ezilahlekileyo zibangela ukubonakaliswa komqondiso kunye norhwaphilizo lwedatha olubonisa njengokuvalwa okungahleliweyo.
Ulawulo lobushushu oluhambelana nendawo yakho
Uphononongo luka-2024 kwi-ACS Omega luvavanye iinkqubo zolawulo lobushushu bebhetri kwaye lwafumanisa ukuba ziinkqubo ezixutyiweyo kuphela ezidibanisa ukupholisa ulwelo kunye nezixhobo zokutshintsha isigaba ziyanelisa iimfuno zobugcisa kusetyenziso oluphezulu{1}} lwemfuno (Lyu et al., "Uphando lweLi{3}}Ion iBattery Thermal Management Systems esekwe kwiMibhobho yoBushushu," ACS4, Omega 2IDO 10.1021/acsomega.3c08056). Ababoneleli abaninzi banikezela ngokupholisa okungenziwayo kuphela, okusebenza kwishifti enye{9}}yangaphakathi kodwa isilele kwiindawo ezininzi{10} zokugcina iimpahla okanye kwindawo ebandayo.
Ugcino olubandayo lufuna izisombululo ezithile. I-Lead-ibhetri zeasidi zilahlekelwa yi-30-35% umthamo kumaqondo obushushu efriji kunye ne-50-60% kwiindawo zesikhenkcisi. I-Lithium eneenkqubo zokufudumeza ezifanelekileyo igcina umthamo we-95% nakwi-22℃F. "Efanelekileyo" ithetha iipleyiti ezidibeneyo zokufudumeza ze-PTC ezisebenza ngaphantsi kwe-5℃, ukutywinwa kwe-IP67 ngokuchasene nokudibanisa, kunye neendawo ezivaliweyo.
