Utility Vehicle Bhatiri Mutengi's Guide
Ndakaona maneja wezvikepe muRiyadh achirasa mabhatiri eeasidhi anokosha $180,000{{2}pashure pemwedzi gumi nemina. Kuchengetera kutonhora, mashifiti matatu, haaikwanisa kubata chaji iri pasi pe15 degree. Sulfation yakadya kuburikidza nemahwendefa. Pakazosvika mwedzi wegumi neimwe forklift yake yakanga ichikamhina nepakati-mashifts.
Anga ari 2019. Ndakabatsira oparesheni yake kufambisa LFP kubva ipapo. Gore rechishanu ikozvino, 87% kuchengetedza simba pamapakiti ekutanga.
The Spec Sheet Dambudziko
Kukanganisa kwakawanda kwekutenga zvinhu kwandinoona kunosvika pakudzingirira nhamba dzisiridzo. Wese munhu anogadzirisa pa$/kWh pakutenga. Zvichida 35% yezvauchazoshandisa.
Ini ndichasvika kuTCO kuparara gare gare, asi kutanga: kuenzanisa masero. Uku ndiko kusiyanisa kwemhando isingambo ratidzike mumabhuku ekutengesa, uye ndiko uko vatengesi vanocheka makona kana vachida kurova mutengo.
Patinoongorora vatengesi, kushivirira kwemasero ndiwo mubvunzo wangu wekutanga. Yekutanga-vagadziri vetier vanoenderana ne ±2.5% kugona uye zvakafanana nemukati kuramba. Sei kuramba kwemukati kuchikosha kupfuura kukwanisa kwepamusoro{{4}maapplication azvino? Nekuti kana iwe uine masero anoenderana nekupikisa kusingaenderane, ikozvino haina kupatsanurwa zvakaenzana. Sero repasi-reresistance rinotora mutoro wakawanda, rinopisa nekukasira, rinokura nekukurumidza, uye rinozokwevera paki yese pasi. MIT yakanyorwa kuti 20% kuramba kusawirirana kunocheka kutenderera hupenyu nekusvika makumi mana muzana pamitengo yakakwira yekuburitsa (sciencedirect.com).
Ndiwo makore ehupenyu hwebasa achinyangarika nekuti mumwe munhu akachengeta madhora matatu pasero pakufananidza.
Iyo grading system inoita kuti zvinyanye. Mushure mekuchaja, maseru anorongwa kuita Giredhi A, B, C, D. Giredhi A inotariswa-inopindirana patsva kubva pamutsetse. Grade B inowanzova Grade A iyo yaigara mudura kwemwedzi mitatu kusvika mitanhatu. Mamiriro akafanana papepa. Kushanda kwemunda kwakasiyana.
Mumwe mutengesi weShenzhen watakaongorora aisanganisa maseru gumi neshanu eGrade B. Same kugona pane yavo database. Mapaketi avo aive achikundikana 30% nekukurumidza kupfuura vakwikwidzi pamutengo wakafanana. Pandakabvunza nezve kushivirira kwavo, mutengesi haana kukwanisa kundipa nhamba. Ndizvo zvakandiudza zvose.
Kugadzira nguva kunokosha zvakare, uye anenge hapana anobvunza nezvazvo. Kugadzira chaiko kunoda kubhadhariswa zvakakwana-kubvisa pamwe nekuzorora kwemazuva gumi nemashanu kuitira kuti zvirema zvioneke. Vatengesi vari pasi pemargin pressure compress iyi. Masero anotakura zvakanaka. Kukanganisa kunobuda mumwedzi wechisere kana wapfuura-padanho rekunongedza munwe.
BMS
Kurumidza pano nekuti munhu wese anowedzera izvi.
Kukwenenzverwa kwegiredhi-: Zvishoma pane kana kuenzana ne0.5% pakunzwa kwazvino. Motokari: isingasviki kana kuenzana ne1%. Mutengi: ndiani anoziva.
Mamiriro-e-yekuchajiswa kunobatanidza nekufamba kwenguva. Kana zvauri kunzwa zvikaita 2%, uri kudzima nguva ichiripo kana kuti -kupedza. Hapana anozviratidza mukuyedzwa kwekugamuchirwa. Ose ari maviri anouraya yako uptime kupfuura 18-24 mwedzi.
Kuenzanisa: passive tsvina 5-10% sekupisa, inodhura zvishoma. Active kutamisa simba pakati pemasero pa95%+ kunyatsoshanda, inowedzera $15-30 per kWh. Vazhinji vatengesi vanotakura vafambi nekuti vatengi havazive kubvunza inoshanda. Kana iwe uchimhanyisa mukana wekuchaja, inoshanda kuenzanisa inobhadhara mukati memakore maviri.
Ndizvo. Fambira mberi.
Tembiricha
Ini ndarasa kuverenga kuti ingani lithium "kutadza" kwandakaongorora kwakava matambudziko ekutonga kwemafuta.
Pazasi 0 dhigirii, usabhadharise lithium. Period. Iwe unowana lithium simbi plating pane anode panzvimbo yekupindirana kwakaringana. Kukuvadzwa kusingadzoreki. Ngozi yemoto kubva pakuumbwa kwe dendrite. Chero chengetedzo inotonhora kana yechando kuendesa kunze inoda kusanganiswa kupisa uye BMS yekuchaja yekuvhara. Ini handina basa kuti pepa remupi wako rinoti kudii nezve renji yekushandisa. Kana vasingakwanise kutsanangura zvakadzama-dziviriro yavo yehutambiricha, famba.
Lead{{0}asidhi ine matambudziko akasiyana ekutonhora. Pazasi pemadhigirii gumi nemashanu, maseru akazara haakwanise kubvuma kubhadharisa kuzere. Iwe urikumhanya pa60-70% kugona uku uchimhanyisa sulfation. Mumwe maneja wezvikepe wekuCanada wandinoziva aishandisa $8,000 pagore pamakamuri ebhatiri anopisa. Haana kumboonekwa mune yake yekutanga TCO modhi nekuti hapana akabvunza nezve ambient tembiricha panguva yekutengesa.
Kupera kwepamusoro: LFP inobata kusvika 60 dhigirii zvinhu zvisati zvashata. NMC yakasimba, pamwe 55 degree. Pack tembiricha musiyano unofanirwa kugara pasi pe5 degree. Kutonhora kwemvura kunoita izvi asi kunowedzera mutengo uye kugadzirisa. Kutonhodza mhepo kunoshanda kana uri pasi pe2C zvichienderera uye ambient inogara iri pasi pe35 degrees .
Chokwadi, hechino chimwe chinhu chandinofanira kutaura tiri patembiricha. Iyo spec sheet inoshanda renji inoreva kuti maseru haafanire kukundikana. Hazvirevi kuita kwakaringana. Pakiti yakarongerwa -20 kusvika 60 dhigirii ichakura nekukurumidza pakunyanyisa. Isu takanga tine mutengi muPhoenix aimhanya ekunze maAGV aisakwanisa kuziva kuti sei mapaketi avo aifa pa60% yehupenyu hwakayerwa kutenderera. Vakashandura midziyo yavo yakagara muzuva rakananga panguva yekuzorora kwemasikati, ichirova 50 degrees + nguva dzose. Nehunyanzvi mukati me spec. Kutouraya masero.
