Mphamvu zazikulu, mphamvu zazikulu, kukula kwazing'ono, kulemera kopepuka, kupanga kosavuta kwa misala, ndi kugwiritsa ntchito zigawo zotsika mtengo ndizovuta popanga mabatire a EV.Mwa kuyankhula kwina, zimadutsa mtengo ndi ntchito.Ganizirani ngati kugwirizanitsa, kumene kilowatt-hour (kWh) yomwe yapezedwa ikufunika kupereka kuchuluka kwakukulu, koma pamtengo wokwanira wopanga.Chotsatira chake, nthawi zambiri mudzawona mafotokozedwe a batire akuwonetsa mtengo wawo wopanga, pamodzi ndi manambala, kuyambira $240 mpaka $280/kWh. pakupanga mwachitsanzo.
O, ndipo tisaiwale chitetezo.Kumbukirani fiasco ya Samsung Galaxy Note 7 zaka zingapo zapitazo, ndi batri ya EV yofanana ndi moto wagalimoto ndi kusungunuka kwapamtunda kwa Chernobyl. paketi kuti muteteze selo limodzi kuti lisawotchere lina, lina, ndi zina zotero, onjezerani zovuta za chitukuko cha batri la EV. Pakati pawo, ngakhale Tesla ali ndi mavuto.
Ngakhale paketi ya batri ya EV ili ndi zigawo zitatu zazikulu: ma cell a batri, makina oyendetsera batire, ndi mtundu wina wa bokosi kapena chidebe chomwe chimawagwirizanitsa, pakadali pano, tingoyang'ana mabatire ndi momwe adasinthira ndi Tesla, koma ndizovuta kwa Toyota.
Batire ya cylindrical 18650 ndi batri ya lithiamu-ion yokhala ndi mainchesi 18 mm, kutalika kwa 65 mm ndi kulemera kwa pafupifupi magalamu 47. Pamagetsi odziwika bwino a 3.7 volts, batire iliyonse imatha kulipira mpaka 4.2 volts ndikutulutsa motsika. monga 2.5 volts, kusunga mpaka 3500 mAh pa selo.
Mofanana ndi ma electrolytic capacitors, mabatire a galimoto yamagetsi a Tesla amakhala ndi mapepala aatali a anode ndi cathode, olekanitsidwa ndi zinthu zotetezera ndalama, zokulungidwa ndi zomangidwa mwamphamvu m'masilinda kuti asunge malo ndi kusunga mphamvu zambiri momwe angathere. Mapepala a anode (otetezedwa bwino) aliyense ali ndi ma tabu olumikizira zolipiritsa zofananira pakati pa ma cell, zomwe zimapangitsa kuti pakhale batire yamphamvu - amawonjezera imodzi, ngati mungafune.
Monga capacitor, imawonjezera mphamvu yake mwa kuchepetsa kusiyana pakati pa anode ndi mapepala a cathode, kusintha dielectric (zomwe zili pamwambazi zotetezera pakati pa mapepala) kuti zikhale ndi chilolezo chapamwamba, ndikuwonjezera dera la anode ndi cathode. Gawo lotsatira mu (mphamvu) Tesla EV batire ndi 2170, yomwe ili ndi silinda yokulirapo pang'ono kuposa 18650, yolemera 21mm x 70mm ndi kulemera mozungulira 68 magalamu. volts ndi kutulutsa otsika ngati 2.5 volts, kusunga mpaka 4800 mAh pa selo.
Pali malonda, komabe, makamaka kukana ndi kutentha motsutsana ndi kufunikira kwa mtsuko wokulirapo pang'ono. Pankhani ya 2170, kuwonjezeka kwa anode / cathode mbale kukula kumabweretsa njira yayitali yolipiritsa, zomwe zikutanthauza kukana kwambiri, motero zambiri. mphamvu yotuluka mu batire monga kutentha ndi kusokoneza kufunikira kwa kulipiritsa mwachangu.
Kuti apange batire ya m'badwo wotsatira wokhala ndi mphamvu zambiri (koma popanda kukana kowonjezereka), akatswiri a Tesla adapanga batire yokulirapo kwambiri yokhala ndi mapangidwe otchedwa "matebulo" omwe amafupikitsa njira yamagetsi motero amachepetsa kutentha komwe kumapangidwa ndi kukana . Zambiri mwa izi zitha kukhala chifukwa cha omwe angakhale ofufuza abwino kwambiri a batri padziko lapansi.
Batire ya 4680 imapangidwa mu mawonekedwe a helix opangidwa ndi matayala kuti apange zosavuta kupanga, ndi phukusi la kukula kwa 46mm m'mimba mwake ndi 80mm kutalika. komabe, selo lililonse limayikidwa mozungulira 9000 mAh, zomwe zimapangitsa kuti mabatire atsopano a Tesla flat-panel akhale abwino.Komanso, kuthamanga kwake kuli bwino kuti afunike mofulumira.
Ngakhale kukulitsa kukula kwa selo lililonse m'malo mocheperachepera kungawoneke ngati kukutsutsana ndi kapangidwe ka batri, kuwongolera mphamvu ndi kuwongolera kwamafuta kwa 4680 poyerekeza ndi 18650 ndi 2170 kudapangitsa kuti ma cell azikhala ochepa poyerekeza ndikugwiritsa ntchito Battery ya 18650 ndi 2170. -Zopangidwa kale za Tesla zili ndi mphamvu zambiri pa batri pa paketi yofanana.
Kuchokera pamawerengero, izi zikutanthauza kuti pafupifupi 960 "4680" maselo omwe amafunikira kudzaza malo omwewo monga 4,416 "2170" maselo, koma ndi zopindulitsa zina monga kutsika mtengo kwa kupanga kWh ndi kugwiritsa ntchito 4680 Paketi ya batri imawonjezera mphamvu kwambiri.
Monga tafotokozera, 4680 ikuyembekezeka kupereka nthawi 5 kusungirako mphamvu ndi mphamvu 6 kuyerekeza ndi batire ya 2170, zomwe zimatanthawuza kuwonjezeka kwa galimoto yomwe ikuyembekezeka kuchoka pa 82 kWh mpaka 95 kWh mu Teslas Mileage yatsopano ikuwonjezeka mpaka 16%.
Kumbukirani, izi ndizo maziko a mabatire a Tesla, pali zambiri kumbuyo kwa teknoloji.Koma ichi ndi chiyambi chabwino cha nkhani yamtsogolo, pamene tiphunzira momwe tingagwiritsire ntchito mphamvu yogwiritsira ntchito mphamvu ya batri, komanso kulamulira nkhani za chitetezo kuzungulira. kupanga kutentha, kutayika kwa mphamvu, ndipo… ndithudi… kuopsa kwa moto wa batri la EV.
Ngati mumakonda All-Things-Tesla, nawu mwayi wanu wogula mtundu wa Hot Wheels RC wa Tesla Cybertruck.
Timothy Boyer ndi mtolankhani wa Tesla ndi EV wa Torque News ku Cincinnati. Wodziwa kukonzanso magalimoto oyambirira, nthawi zonse amabwezeretsa magalimoto akale ndikusintha injini kuti apititse patsogolo ntchito. Tsatirani Tim pa Twitter @TimBoyerWrites pa nkhani za tsiku ndi tsiku za Tesla ndi EV.
