Ingabe lawa kuzoba amabhethri e-Tesla amasha? 15 3 imijikelezo yokusebenza, 175+ million km, 250-XNUMX iminyaka (!) Ukusebenza
UJeff Dan, usosayensi wakwaTesla nongomunye wochwepheshe abakhulu emhlabeni uma kukhulunywa ngamaseli e-lithium-ion, uncome imiphumela yokuhlolwa yohlobo olusha lwamaseli. Bayakwazi ukumelana nemijikelezo yokusebenza eyinkulungwane eyi-10-15 ngaphandle kokulahlekelwa okukhulu kwamandla. Lokho kusho ukuthi amakhilomitha ayizigidi ezi-3,5, okuthi noma ukusuka kumakhilomitha angama-20 ngonyaka kusho iminyaka eyi-175 yokushayela.
Ngokuxhashazwa kwezibalo kwePole iminyaka engaphezu kuka-250 yokushayela!
Amaseli amasha ka-Dan - awavumele asebenze kumjikelezo we-50-> 25% futhi azohlala unomphela
Imiphumela eyethulwe ngu-Dahn isikhumbuza futhi ukuthi kungani ukuthuthukiswa kwamabhethri e-lithium-ion kubonakala kuhamba kancane. Kuhle amanye amaseli awaklama ayesemishinini yokuhlola iminyaka emithathu. futhi yafinyelela endaweni yemijikelezo eyi-10 350. Waba yini umphumela? Uma ibhethri elakhelwe phezu kwesisekelo salo linikeza ibanga elingamakhilomitha angama-XNUMX, imoto ngabe ihambe amakhilomitha ayizigidi ezi-3,5:
Wonke amagrafu abonisa ukwehla komthamo weseli uma kuqhathaniswa nemijikelezo yomsebenzi. Ezingakwesobunxele zilayishwa zisuka ku-0 ziye ku-80%, ezimaphakathi zisuka ku-0 ziye ku-90%, ezingakwesokudla zisuka ku-0 ziye ku-100%.
Amagrafu afanekisela:
- C/20 - ukushaja ngamandla amancane we-1/20 webhethri. Emotweni evamile, kuzoba ngu-2-5 kW,
- C/2 - ukushaja umthamo ongu-1/2, okungukuthi ibhethri engu-74 (80) kWh - 40 kW,
- 1C, 2C, 3C - ukushaja ngomthamo webhethri ongu-1x, 2x kanye no-3x. Uma sithatha ibhethri ye-Tesla Model 3 njengesisekelo, khona-ke kuyoba ngu-80, 160 no-240 kW.
Kulula ukubona ukuthi ukwehla okukhulu kwebhethri kwenzeka ngebhethri elinamandla kulo lonke uhla olutholakalayo (igrafu enamachashazi, emagebhugebhu kwesokudla). Akekho umkhiqizi wezimoto owenza lokhu namuhla.
Lapho ingosi ye-Electrek (umthombo) ibanjwa, u-Dan wahambisa imiphumela yocwaningo kwezinye izixhumanisi... Ngemva kwamahora angu-20 okusebenza (izinsuku ezingu-833 = izinyanga ezingu-27,78 = iminyaka engu-2,3) asenombolo yomjikelezo we-15. Futhi yize lapho bephuma ngo-100% ungabona ukwehla kancane kwamandla abo (umugqa oluhlaza) kanye nokuguquguquka okungajwayelekile ekugcineni, ngomjikelezo wamaphesenti angama-50-> 25-> 50, akukho ukucekelwa phansi:
Masigcizelele: sibhekene nemijikelezo yokusebenza eyi-15 350. Ukube amaseli ebesebhethrini lemoto kagesi ehamba ibanga elingamakhilomitha ayi-XNUMX, imoto izoba nebanga elingu 1,3 million (25% cycle) noma 2,6 million (50% cycle) amakhilomitha! Ngaleso sikhathi, amaseli e-lithium-ion asetshenziswa komakhalekhukhwini athathwa njengamahle uma ekwazi ukumelana nemijikelezo engama-500-700 ...
> Ilebhu, enikwa amandla yi-Tesla, izidla ngezinto ezizomelana nezigidi zamakhilomitha.
Isethulo sonke singabukwa kuvidiyo engezansi. Akukacaci ukuthi ngabe uJeff Dunn (kwesokudla) ukhuluma ngezixhumanisi asebenzela kuzo uTesla. Mhlawumbe kuzoba yisizukulwane esilandelayo kuphela, ngoba idivayisi enikezela ngemijikelezo yemisebenzi eyi-10 noma ngaphezulu ... isahlolwa:
Njengamanje uTesla umemezela amaseli angu-4680 anokuqukethwe kwe-nickel ephakeme kanye nokuqukethwe kwe-cobalt ephansi. Ngokuzayo bazosebenzisa i-lithium, i-nickel ne-manganese kuphela, futhi i-cobalt izokhishwa ngokuphelele kubo:
> Ingabe amaseli angu-4680 kumabhethri amasha kaTesla azopholiswa kusukela phezulu nangaphansi? Kusukela ngezansi kuphela?
Lokhu kungase kube nentshisekelo kuwe:
