Kodi Lithium-Module ya Batri ya Ion N'chiyani?
CATL inatumiza selo yake yoyamba-kuti-kulongedza batire mu September 2019. Pofika chakumapeto kwa 2023, pafupifupi theka la magalimoto amagetsi atsopano ogulitsidwa ku China anali atasiya mphamvu zake zonse. Ziwerengerozi ndizovuta kutsutsa-CTP 3.0 imakankhira kuchuluka kwa magwiritsidwe ntchito kufika pa 72%, kuchoka pa 55% mu-mapangidwe oyambirira. BYD's blade battery, Tesla's structural paketi, Leapmotor's CTC zomangamanga. Kuchulukira kwamakampani kumawonekera mopanda ma module.
Ndiye n'chifukwa chiyani timapanga ma modules?
Chifukwa ma forklift si magalimoto onyamula anthu. Ngakhalenso ma AGV, ma locomotives a migodi, kapena kukoka kwa eyapoti. Ndipo ma tradeoffs a uinjiniya omwe amapangitsa CTP kukhala yanzeru kwa ma EVs imapangitsa kukhala kovuta kwa zida zamafakitale.
Vuto la Serviceability
Mwiniwake wa Model Y sasinthanitsa paketi yake ya batri. Amayendetsa galimoto kupita kumalo operekera chithandizo. Phukusili limakhala m'galimoto kwa moyo wake wonse pokhapokha ngati pachitika ngozi.
Malo osungiramo katundu omwe ali ndi mashifiti atatu alibe mwayi wotere. Batire la forklift likakhala ndi vuto nthawi ya 2 AM, wina amayenera kulizindikira, kulipatula, ndikulikonza popanda kutumiza gawo lonse kufakitale.
Ndi zomwe ma modules amachita. Amapanga malire olakwika.
Phukusi la forklift la 1P48S nthawi zambiri limayendetsa ma module anayi a 12S. Ma cell 37 akakhala oyipa-ndipo ma cell sakuyenda bwino, izi zimangokhala zenizeni pa masauzande a mayunitsi-mumakoka gawo lomwe lakhudzidwa. Ena atatuwo akugwirabe ntchito. Kutsika kwathunthu: mwina ola limodzi ngati muli ndi zosungira. Fananizani izi ndi paketi ya CTP pomwe cell 37 ndi yokhazikika. Mukuyang'ana m'malo mwa paketi yonse, poganiza kuti OEM imathandizira ntchito yakumunda.
Masamu amasintha pamene nthawi yopuma imawononga $ 200-400 pa ola limodzi pamalo otanganidwa ogawa. Kusinthana kwa ma module a $ 3,000 kumaposa $15,000 m'malo mwa paketi kuphatikiza masiku awiri akudikirira mayendedwe.
Zomwe zili Mkati
Tsegulani gawo ndipo mupeza okayikira mwachizolowezi: maselo a prismatic (nthawi zina cylindrical, kutengera ntchito), mabasi a CCS olumikiza ma terminals, gulu la kapolo la BMS lomwe limagwira voteji ndi kuyang'anira kutentha, chimango cha pulasitiki cha kapangidwe kake, mbale zomaliza zachitsulo zoponderezedwa. Kachidutswa kakang'ono kakufunika-ma cell a lithiamu amatupa panthawi yolipiritsa, ndipo popanda kukanikiza nthawi zonse mumakumana ndi zovuta zomwe zimayambitsa kuwonongeka.
Kuwongolera kutentha kumakhalanso kuno. Ma module ambiri a forklift amayendetsa kuziziritsa kwapang'onopang'ono kapena mpweya wokakamiza. Mapulogalamu apamwamba{{2}amagetsi-akuganiza zolemetsa{4}magalimoto kapena zida zamigodi-zimafunika kuziziritsa kwamadzi kophatikizana ndi gawo la module. Ma mbale ozizira, kufalikira kwa glycol, ntchito. Zenera la 20-30℃ntchito silingatheke ngati mukufuna moyo wozungulira womwe pepala limalonjeza.
Palibe mwa izi ndiukadaulo wachilendo. Chofunikira ndi kupha: mtundu wa weld pamabasi, kulondola kwa kuyika kwa NTC thermistor, torque specs pa compression hardware. Zinthu zotopetsa zomwe zimalekanitsa gawo la 2,000-cycle module kuchokera ku 3,500-cycle module.
Industrial Logic vs. EV Logic
Mawonekedwe a EV
Dziko la EV limakwaniritsa kachulukidwe wamagetsi komanso mtengo wopangira pamlingo waukulu. CTP imamveka pamene mukupanga mapaketi 500,000 ofanana pachaka ndipo makasitomala anu samakhudza batire.
Malingaliro a Industrial
Zida zamafakitale zimagwira ntchito mosiyana. Ma voliyumu ndi otsika. Masinthidwe amasiyanasiyana-ma voltage osiyanasiyana, mphamvu zosiyanasiyana, mawonekedwe osiyanasiyana a chassis. Wopanga mapaketi a batire omwe amagwiritsa ntchito zinthu amafunikira kusinthasintha komwe omanga a CTP amavutikira kupereka.
Ma module amakupatsirani kusinthasintha. Pangani gawo lolimba la gawo la 12S, litsimikizireni kamodzi, kenako sinthani mapaketi a 36V/48V/72V/80V powerengera mosiyanasiyana. Mtolo woyenerera umatsika kwambiri poyerekeza ndi kupanga paketi iliyonse kuyambira pachiyambi.
Ichi ndichifukwa chake ogulitsa mabatire ambiri a lithiamu amatumizabe ma module{{0}based systems. Osati chifukwa tili kumbuyo kwa luso laukadaulo-timayang'ana zomwe CATL ndi BYD akuchita monga wina aliyense. Chifukwa zofunikira zogwiritsira ntchito ndizosiyana, ndipo zachuma zimakonda mayankho osiyanasiyana.
Zomwe Mungafunse Wothandizira Anu
Ngati mukuwunika njira za batri ya lithiamu pa ma forklift, ma AGV, kapena zida zofananira nazo, gawo-zochulukira zimakuuzani zambiri kuposa{1}}zambiri zamalonda. Mafunso ena oyenera kufunsa:
- Maselo-ku- magetsi ofananira ndi ma cell akamayendera{2}}amakhala olimba kwambiri, 5mV kapena kuchepera pamlingo wa module akuwonetsa kuwongolera koyenera.
- Kutsimikizira kwa kutentha kwadzaza-funsani data yoyeserera yomwe ikuwonetsa kutentha kwa gawo lonse movoteredwa pano. Ngati iwo sangakhoze kuzitulutsa izo, iyo ndi mbendera yofiira.
- Zomangamanga za BMS-makina apakati ndi otchipa koma ochedwa kuyankha. Kugawidwa (bolodi la akapolo pa module) kumawononga ndalama zambiri koma kumagwira mavuto mofulumira.
- Magawo a utumiki wakumunda-kodi magawo angasinthidwe okha? Kodi njira yodziwira matenda ndi yotani? Kodi amasunga zotsalira kapena zonse zakonzedwa? Wokondedwa aliyense wamkulu wa lithiamu batire OEM ayenera kukhala ndi mayankho omveka bwino a mafunsowa.
Nambala zamutu-zamoyo wanthawi zonse, kachulukidwe ka mphamvu, mtengo pa kWh-ndizocheperako kuposa momwe zimagwirira ntchito. Phukusi lomwe limafika pamapepala koma osatha kutumikiridwa bwino ndi udindo pamalo ogwiritsidwa ntchito kwambiri-.
Choonadi Chotopetsa
Timapanga ma module chifukwa amagwira ntchito zomwe timapereka. Makampani a EV amatha kuthamangitsa mapangidwe opanda module chifukwa zopinga zawo ndizosiyana. Zipangizo zamafakitale zimafunika kusamalidwa bwino, kusanjika, ndi kutha kwa ntchito zomwe gawo{{2}lotengera kamangidwe kake kamagwirabe ntchito bwino.
Zimenezo zikhoza kusintha. Njira za CTP zimapitilirabe kuyenda bwino, ndipo pamapeto pake kusiyana kwa magwiridwe antchito kumatha kuchepera kuti mphamvu zochulukirapo zimakhala zoyenerera. Koma pakadali pano, ngati mukuyang'ana mabatire amagetsi opangira ma forklift kapena ma AGV kapena zida zilizonse zomwe zimakhala zofunikira, ma module amakhalabe chisankho chanzeru.
Osati zokongola.
Zothandiza basi.
