Utility Vehicle Battery Buyer's Guide
Ndinaona woyang'anira zombo ku Riyadh akutaya mabatire a asidi okwana $180,000- patatha miyezi 14. Kusungirako kuzizira, mashifiti atatu, sikunathe kupirira pansi pa madigiri 15. Sulfation amadya kudzera m'mbale. Pofika mwezi wa 11 ma forklift ake anali akuyenda pang'onopang'ono-mashift.
Umenewo unali 2019. Ndathandizira opaleshoni yake kuyendetsa LFP kuyambira pamenepo. Chaka chachisanu tsopano, 87% kusunga mphamvu pamapaketi oyambilira.
Vuto la Spec Sheet
Zolakwa zambiri zogula zinthu zomwe ndikuwona zimabwera pakuthamangitsa manambala olakwika. Aliyense amakonza $/kWh pogula. Izi mwina ndi 35% ya zomwe mudzawononge.
Ndifika pakuwonongeka kwa TCO pambuyo pake, koma choyamba: kufananitsa ma cell. Uku ndiye kusinthika kwamtundu komwe sikumawonekera m'mabuku ogulitsa, ndipo ndipamene ogulitsa amadula ngodya akafuna kugunda mtengo.
Tikawunika ogulitsa, kulekerera kwa ma cell ndi funso langa loyamba. -opanga magawo oyamba amafanana ndi kuchuluka kwa ±2.5% ndi kukana kwamkati komweko. Chifukwa chiyani kukana kwamkati kuli kofunika kwambiri kuposa kuchuluka kwa{4}mapulogalamu apano? Chifukwa mukakhala ndi ma cell ofananira omwe ali ndi kukana kosagwirizana, apano samagawanika mofanana. Maselo ocheperako-amatenga katundu wambiri, amatenthedwa, amakalamba mwachangu, ndipo pamapeto pake amakokera paketi yonse pansi. MIT idalemba kuti 20% kukana kusagwirizana kumachepetsa moyo wozungulira pafupifupi 40% pamitengo yayikulu yotulutsa (sciencedirect.com).
Ndi zaka za moyo wautumiki zikuzimiririka chifukwa wina adasunga $ 3 pa selo pakufananitsa.
Dongosolo la grading limapangitsa kuti izi ziipire. Akamaliza kuchajisa, ma cell amasanjidwa kukhala giredi A, B, C, D. Gulu la A ndilokhazikika-lomwe limagwirizananso. Gulu B nthawi zambiri ndi Giredi A yomwe idakhala m'nkhokwe kwa miyezi itatu kapena isanu ndi umodzi. Zolemba zofanana pamapepala. Kugwira ntchito kosiyanasiyana.
Wothandizira m'modzi wa Shenzhen yemwe tidafufuza anali kusakaniza ma cell 15% a Gulu B. Kuthekera kofananako pamasamba awo. Mapaketi awo anali kulephera 30% mwachangu kuposa opikisana nawo pamtengo womwewo. Nditafunsa za kulolerana kwawo, wogulitsa sakanakhoza kundipatsa nambala. Izo zinandiuza ine chirichonse.
Kupanga nthawi kumafunikanso, ndipo pafupifupi palibe amene amafunsa za izi. Kupanga koyenera kumafunika ndalama zonse-kutulutsa kokwanira komanso kupuma kwa masiku 15 kuti zolakwika ziwonekere. Othandizira omwe ali pansi pa maginito apanikiza izi. Ma cell amayenda bwino. Zowonongeka zimayamba mwezi wa 8 mukadutsa-pokuloza chala.
BMS
Fulumira apa chifukwa aliyense amasokoneza izi.
Magiredi a Industrial-: Ochepera kapena ofanana ndi 0.5% pakumva kwapano. Zagalimoto: Zochepera kapena zofanana ndi 1%. Wogula: ndani akudziwa.
Chiyerekezo cha-cha{1}}cha mtengo chikugwirizana ndi nthawi. Ngati zomverera zanu zikuyenda pang'onopang'ono 2%, mwina mukutseka msanga kapena{4}}mwayimitsa. Palibenso kuwonekera pakuyezetsa kuvomereza. Onsewa amakupha nthawi yanu yopitilira miyezi 18-24.
Kulinganiza: zinyalala zopanda 5-10% monga kutentha, zimawononga ndalama zochepa. Kusamutsa mphamvu pakati pa ma cell pa 95% +, kumawonjezera $ 15-30 pa kWh. Otsatsa ambiri amangotumiza osachitapo kanthu chifukwa ogula sadziwa kufunsa kuti agwire ntchito. Ngati mukugwiritsa ntchito mwayi wolipiritsa, kuchita bwino kumalipira pasanathe zaka ziwiri.
Ndichoncho. Pitilirani.
Kutentha
Ndataya kuchuluka kwa lifiyamu "zolephera" zomwe ndafufuza zomwe zidakhala zovuta zowongolera matenthedwe.
Pansi pa 0 digiri, musalipiritse lithiamu. Nthawi. Mumapeza zitsulo za lithiamu pa anode m'malo molumikizana bwino. Zowonongeka zosasinthika. Kuopsa kwa moto kuchokera ku mapangidwe a dendrite. Kusungirako kulikonse kozizira kapena kutumizidwa kunja kwanyengo yozizira kumafunikira kutenthetsa kophatikizika ndi kutsekeka kwa BMS. Sindisamala zomwe supplier yanu ikunena za kuchuluka kwa magwiridwe antchito. Ngati sangathe kufotokozera{8}}kutsika kwawo kwa kutentha mwatsatanetsatane, yendani.
Lead{{0}acid ali ndi mavuto osiyanasiyana ozizira. Pansi pa madigiri 15, ma cell osefukira sangathe kuvomera zonse. Mukuthamanga pa 60-70% mphamvu pamene mukufulumizitsa sulfation. Woyang'anira zombo wina waku Canada yemwe ndimamudziwa anali kuwononga $8,000 pachaka pazipinda zotentha za batri. Sanawonekere pachitsanzo chake choyambirira cha TCO chifukwa palibe amene adafunsa za kutentha kozungulira pakugulitsa.
Mapeto apamwamba: LFP imagwira mpaka madigiri 60 zinthu zisanachitike. NMC ndi yothina, mwina madigiri 55. Kusiyanasiyana kwa kutentha kwa paketi kuyenera kukhala pansi pa 5 digiri. Kuziziritsa kwamadzi kumachita izi koma kumawonjezera mtengo ndi kukonza. Kuziziritsa mpweya kumagwira ntchito ngati muli pansi pa 2C mosalekeza ndipo malo ozungulira amakhala pansi pa 35 digiri.
Kwenikweni, pali china chake chomwe ndiyenera kutchula tikakhala kutentha. Magawo ogwiritsira ntchito ma sheet amatanthauza kuti ma cell salephera nthawi yomweyo. Izi sizikutanthauza magwiridwe antchito abwino. Phukusi lovotera -20 mpaka 60 digiri likupita kukalamba mofulumira kwambiri. Tidali ndi kasitomala ku Phoenix yemwe amayendetsa ma AGV akunja omwe sanathe kudziwa chifukwa chake mapaketi awo amafa pa 60% ya moyo wozungulira. Zida zawo zidakhala padzuwa lolunjika panthawi yopuma masana, kugunda madigiri 50 + pafupipafupi. Mwaukadaulo mkati mwa spec. Pafupifupi kupha maselo.
Mtengo wa TCO
Chabwino, manambala. Ndatengera izi kuchokera ku pulojekiti ya Texas 3PL yomwe tidachita mu 2024. 50 Class I forklifts, two-shift schedule, 8-year analysis:

LFP imalekerera nkhanza. Kutulutsa kwakuya, kutsika pang'ono, kusinthasintha kwa kutentha. Kulemera pa kWh iliyonse kuposa NMC, zomwe zimafunika ngati ndinu wolemera-ndiochepera. Mapulogalamu ambiri a forklift ndi AGV sali.
NMC imamveka ngati kulemera kuli kofunikira ndipo mutha kuthana ndi zofunikira pakuwongolera kutentha. Moyo wamfupi wozungulira, wokwera mtengo. Zida zosungiramo katundu sizimalungamitsidwa.
Lead{{0}acid akadali mapensulo{1}}osagwiritsa ntchito kamodzi{2}}kamodzi kokha{2}}zosintha zomwe zidalipo kale ndipo palibe mwayi wolipiritsa. Ingomvetsetsani kuti mukudzipereka kuzaka 4 zosinthira ndikukonza sabata iliyonse.
Pang'ono pang'ono, koma ndiyenera kuthana ndi kukula kwa-mapulogalamu olemetsa chifukwa ndimawona zolakwika zomwezi.
Phukusi la 600kWh silimawononga 2x zomwe paketi ya 300kWh imawononga. Zili ngati 2.3-2.5x. Thermal management ndi structural engineering scale mopanda mzere.
Tidayerekeza paketi yamagalimoto ya 600kWh ndi makina osungira 600kWh chaka chatha. Maselo omwewo, chemistry yofanana. Paketi yamagalimoto: pafupifupi $ 2.50 / Wh yokhala ndi kuziziritsa kwamadzi kwa 3C kutulutsa, kamangidwe ka 800V, mpanda wa aluminiyamu. Malo osungira: pafupifupi $ 1.15 / Wh ndi kuziziritsa mpweya, kabati yachitsulo. Phukusi lagalimoto limawononga kawiri chifukwa 35% imapita ku kasamalidwe kamafuta komanso mawonekedwe opepuka.
Funsani ma quotes pazigawo zingapo. Yang'anani pamapindikira a $/Wh.
Othandizira
CATL ili ndi pafupifupi 38% ya mphamvu ya lifiyamu-ya padziko lonse lapansi. BYD wina 16%. Supply chain ndi yodziwikiratu kuposa zaka zisanu zapitazo, njira zina zocheperako ngati china chake sichikuyenda bwino ndi omwe akukugulirani.
Othandizira amchigawo akhoza kukhala bwino. Kusamala ndikofunikira kwambiri. Tsimikizirani kupezeka kwa ntchito mu geography yanu. Pezani malifalensi kuchokera kwa makhazikitsidwe omwe ali ndi zaka 3+ mumapulogalamu ofanana. Onani kukhazikika kwachuma. Tawona ogulitsa angapo akutuluka pamsika mkati mwa miyezi 24, kusiya makasitomala ndi mapaketi a $ 25,000 ndipo alibe chitsimikizo. Mmodzi wa membala wa MHEDA ku ProMat adandiuza kuti adataya ntchito zake zonse pomwe wopereka katundu adapinda miyezi 18 atatumizidwa.
Mabatire okonzedwanso: kusiyanasiyana kwamtundu ndikokwera kwambiri. Katswiri wina wa forklift pabwalo lamakampani adafotokoza kuti "lotale, mwina 3 mwa 10 zaka 2-3 zapitazi, zina zimalephera m'miyezi ingapo." Ngati mukuganiza zokonzanso, funani data yoyezetsa ma cell ndi chitsimikizo kuchokera ku kampani yomwe ili ndi katundu weniweni.
Mafunso kwa ogulitsa anu RFQ:
- Kulekerera kwa ma cell pa mphamvu ndi kukana kwamkati?
- Grade A zokolola? Ndondomeko ya ma cell a Sitandade B?
- Nthawi yopuma yokonzekera musanalembe?
- Kulekerera kwa BMS calibration?
- Kusanja mochitachita kapena kungokhala chete?
- Nthawi yoyankha ntchito zachigawo?
- Maumboni atatu akugwiritsa ntchito malonda anu zaka 3+ mumtundu wanga wa pulogalamu?
- Ndondomeko yofunsira chitsimikizo?
- Kodi chimachitika ndi chiani ngati kampani yanu ipindika?
Ngati sangathe kuyankha izi mwachindunji, izo zimakuuzani chinachake za ntchito yawo.
Polinovel
Timapanga mapaketi a LFP amagalimoto ogwiritsira ntchito. Kuyambira 2012. Forklifts, AGVs, ngolo za gofu, chithandizo chapansi.
Sindikunamizira kuti sitilowerera ndale pano. Tili ndi chidwi ndi malonda pakutengera kwa lithiamu. Zomwe ndingakuuzeni: makasitomala omwe amabwereranso kuti awonjezere zombo ndi omwe tidawathandiza kupanga chisankho choyenera nthawi yoyamba, ngakhale pamene chisankhocho chinali "lithiamu sichimveka bwino pa ntchito yanu."
Pali chowerengera cha TCO pa polinovelpowbat.com chomwe chimayendetsa magawo anu. Shift schedule, kutentha, mitengo yamagetsi, zomangamanga zomwe zilipo. Osati pachipata. Ngati masamu sakugwira ntchito pa lithiamu, chowerengera chimakuwonetsani zimenezo.
