Hukuru hwesimba, simba guru, hukuru hudiki, huremu huremu, nyore kugadzira hukuru, uye kushandiswa kwezvikamu zvakachipa zvinonetsa pakugadzira mabhatiri eEV.Nemamwe mashoko, inovira kusvika pamutengo uye kushanda.Funga nezvazvo sechiito chekuenzanisa, apo iyo kilowatt-awa (kWh) yakawanikwa inoda kupa huwandu hwepamusoro, asi nemutengo unonzwisisika wekugadzira.Nekuda kweizvozvo, iwe unowanzoona bhatiri paki tsananguro inorongedzera mutengo wavo wekugadzira, pamwe nenhamba, kubva ku $240 kusvika ku $280/kWh. panguva yekugadzira, semuenzaniso.
O, uye ngatisakanganwe kuchengetedza.Yeuka Samsung Galaxy Note 7 fiasco makore mashoma apfuura, uye EV bhatiri yakaenzana nemoto wemotokari uye Chernobyl yakaenzana meltdowns.Murunaway chain reaction disaster scenario, spacing and thermal controls pakati pemaseru mubhatiri. pack kudzivirira imwe sero kubva pakupisa imwe, imwe, nezvimwewo, kuwedzera kune kuoma kweEV bhatiri yekuvandudza.Pakati pavo, kunyange Tesla ane matambudziko.
Nepo EV bhatiri paki ine zvikamu zvitatu zvikuru: masero ebhatiri, bhatiri manejimendi system, uye imwe mhando yebhokisi kana mudziyo unovabata pamwechete, parizvino, isu tichangotarisa mabhatiri uye kuti akashanduka sei neTesla, asi ichiri dambudziko reToyota.
Iyo cylindrical 18650 bhatiri inonzi lithium-ion bhatiri ine dhayamita ye18 mm, kureba kwe65 mm uye uremu hunenge magiramu 47. Pazita remagetsi e3.7 volts, bhatiri rimwe nerimwe rinogona kutengesa kusvika ku4.2 volts uye kubudiswa kwakaderera. se 2.5 volts, ichichengeta kusvika ku3500 mAh pasero.
Zvakawanda se electrolytic capacitors, mabhatiri emotokari yeTesla ane mashizha akareba eanode uye cathode, akaparadzaniswa necharge-insulating material, yakapetwa uye yakanyatsoiswa mumasilinda kuchengetedza nzvimbo uye kuchengetedza simba rakawanda sezvinobvira.Idzi cathode (negatively charged) uye anode (yakanatswa) mapepa ega ega ane ma tabo ekubatanidza macheji akafanana pakati pemasero, zvichikonzera bhatiri rine simba-vanowedzera kusvika kune rimwe, kana uchida.
Kungofanana necapacitor, inowedzera simba rayo nekudzikisa nzvimbo pakati peanode uye cathode mapepa, kushandura dielectric (iyo iri pamusoro inodzivirira zvinhu pakati pemapepa) kune imwe ine mvumo yepamusoro, uye kuwedzera nzvimbo yeanode uye cathode. Nhanho inotevera mu (simba) Tesla EV bhatiri ndeye 2170, iyo ine humburumbira yakati kurei kupfuura 18650, inoyera 21mm x 70mm uye huremu hwakapoteredza 68 gramu. volts uye kuburitsa zvakaderera se2.5 volts, kuchengetedza kusvika 4800 mAh pasero.
Pane kutengeserana, zvisinei, izvo zvinonyanya kupikisa uye kupisa kunopesana nekuda chirongo chakati kurei.Panyaya ye2170, kuwedzera kweanode / cathode plate size inokonzeresa yekuchaja nzira, zvinoreva kuramba zvakanyanya, nekudaro zvakanyanya. simba richibuda mubhatiri sekupisa uye kukanganisa kukurumidza kuchaja kunodiwa.
Kugadzira bhatiri rechizvarwa chinotevera rine simba rakawanda (asi pasina kuwedzera kushorwa), mainjiniya eTesla akagadzira bhatiri rakakura zvakanyanya neinonzi "tafura" dhizaini inopfupisa nzira yemagetsi uye nokudaro inoderedza kuwanda kwekupisa kunokonzerwa nekupikisa . Zvizhinji zveizvi zvinogona kuverengerwa kune angave akanakisa bhatiri vaongorori munyika.
Iyo 4680 bhatiri yakagadzirwa mune tiled helix fomu kuti zvive nyore kugadzira, nehukuru hwepakeji ye 46mm muhupamhi uye 80mm pakureba.Kurema hakusipo, asi mamwe maitiro emagetsi anonzi akafanana kana kuti akafanana;zvisinei, sero imwe neimwe inotaridzirwa kumativi e9000 mAh, izvo zvinoita kuti itsva Tesla flat-panel mabhatiri akanaka.
Ndichiri kuwedzera saizi yesero rega rega pane kudzikira kungaite kunge kunopesana nezvinodiwa nebhatiri dhizaini, kuvandudzwa kwesimba uye kutonga kwekupisa kwe4680 zvichienzaniswa ne18650 ne2170 zvakakonzera kuti masero mashoma zvichienzaniswa nekushandisa 18650 uye 2170 Bhatiri. -powered kare Tesla modhi dzine simba rakawanda pabhatiri pack yehukuru hwakafanana.
Kubva pamaonero enhamba, izvi zvinoreva kuti maseru angangoita 960 "4680" chete anodiwa kuzadza nzvimbo yakafanana ne4,416 "2170" maseru, asi nemamwe mabhenefiti akadai semutengo wakaderera wekugadzira pakWh uye kushandisa 4680 Iyo bhatiri paki inowedzera simba zvakanyanya.
Sezvambotaurwa, iyo 4680 inotarisirwa kupa kashanu simba rekuchengetedza uye ka6 simba richienzaniswa ne2170 bhatiri, izvo zvinoshandura kune inotarisirwa kuwedzera kwekutyaira kubva pa82 kWh kusvika 95 kWh muTeslas Mileage nyowani inowedzera kusvika ku16%.
Rangarira, izvi zvinongova zvekutanga zvemabhatiri eTesla, kune zvakawanda kuseri kwehunyanzvi.Asi iyi ndiyo yekutanga yakanaka yenyaya yeramangwana, sezvatichadzidza kubata bhatiri pack simba rekushandisa, pamwe nekudzora nyaya dzekuchengetedza dzakapoteredza. kugadzirwa kwekupisa, kupera simba, uye…zve… njodzi yekutsva kwebhatiri reEV.
Kana iwe uchida Zvese-Zvinhu-Tesla, heino mukana wako wekutenga Hot Wheels RC vhezheni yeTesla Cybertruck.
Timothy Boyer mutori wenhau weTesla uye EV weTorque News muCincinnati.Ane ruzivo mukugadzirisa kwekutanga kwemotokari, anogara achidzorera motokari dzakwegura uye anoshandura injini kuti avandudze kushanda.Tevera Tim pa Twitter @TimBoyerWrites yezuva nezuva Tesla neEV nhau.
