Umthamo omkhulu, amandla amakhulu, ubungakanani obuncinci, ubunzima obulula, ukuveliswa kobunzima obulula, kunye nokusetyenziswa kwamacandelo angabizi kakhulu yimingeni ekuyileni iibhetri ze-EV.Ngamanye amazwi, ubilisa iindleko kunye nokusebenza.Cinga njengesenzo sokulinganisa, apho i-kilowatt-yure (kWh) ephunyeziweyo idinga ukubonelela ngoluhlu oluphezulu, kodwa ngexabiso elifanelekileyo lokuvelisa. Ngenxa yoko, uya kuhlala ubona iinkcazo zepakethi yebhetri edwelisa iindleko zabo zokuvelisa, kunye namanani, ukusuka kwi-$240 ukuya kwi-$280/kWh. ngexesha lemveliso, umzekelo.
Owu, kwaye masingalibali ukhuseleko.Khumbula i-Fiasco ye-Samsung Galaxy Note 7 kwiminyaka embalwa edlulileyo, kunye ne-EV yebhetri elingana nemililo yemoto kunye ne-Chernobyl efanayo meltdowns.Kwimeko yentlekele yokusabela kwekhonkco, isithuba kunye nolawulo lobushushu phakathi kweeseli kwibhetri. ipakethe yokukhusela iseli enye ekutshiseni enye, enye, njl., Yongeza ubunzima bophuhliso lwebhetri ye-EV.Phakathi kwabo, noTesla uneengxaki.
Ngelixa ipakethe yebhetri ye-EV inamacandelo amathathu aphambili: iiseli zebhetri, inkqubo yolawulo lwebhetri, kunye nohlobo oluthile lwebhokisi okanye isikhongozeli esizibambayo, okwangoku, siza kujonga nje iibhetri kunye nendlela ezivele ngayo ngeTesla, kodwa kuseyingxaki kwiToyota.
Ibhetri ye-cylindrical 18650 ibhetri ye-lithium-ion kunye nobubanzi be-18 mm, ubude be-65 mm kunye nobunzima malunga ne-47 grams. Kwi-voltage ye-3.7 volts, ibhetri nganye inokuhlawula ukuya kwi-4.2 volts kwaye ikhuphe njengephantsi. njengoko 2.5 volts, ukugcina ukuya 3500 mAh iseli nganye.
Ngokufana ne-electrolytic capacitors, iibhetri zemoto zombane zeTesla ziqukethe amashidi amade e-anode kunye ne-cathode, ehlulwe yimpahla yokukhusela intlawulo, ihlanganiswe kwaye ifakwe ngokuqinileyo kwiisilinda ukugcina indawo kunye nokugcina amandla amaninzi kunokwenzeka. Amaphepha e-anode (ahlawulwe kakuhle) ngamnye aneethebhu zokudibanisa iintlawulo ezifanayo phakathi kweeseli, okubangelwa ibhetri enamandla-zongeza enye, ukuba uyathanda.
Kanye njenge-capacitor, yongeza amandla ayo ngokunciphisa isithuba phakathi kwe-anode kunye ne-cathode sheets, ukutshintsha i-dielectric (izinto ezikhuselayo ezingentla phakathi kwamaphepha) ukuya kwelinye elinemvume ephezulu, kunye nokwandisa indawo ye-anode kunye ne-cathode. Isinyathelo esilandelayo kwi-(amandla) ibhetri ye-Tesla EV yi-2170, ene-cylinder enkulu kancinane kune-18650, ilinganisa i-21mm x 70mm kunye nobunzima obujikeleze i-68 grams. iivolthi kunye nokukhutshwa okuphantsi njenge-2.5 volts, ukugcina ukuya kwi-4800 mAh ngeseli nganye.
Kukho ukurhweba, nangona kunjalo, ubukhulu becala bumalunga nokuchasa kunye nobushushu ngokuchasene nokufuna ingqayi enkulu. Kwimeko ye-2170, ukwanda kwe-anode / ubungakanani beplate yecathode kubangela indlela yokutshaja ende, okuthetha ukuxhathisa ngakumbi, ngaloo ndlela ngaphezulu. amandla aphuma kwibhetri njengobushushu kwaye aphazamise imfuneko yokutshaja ngokukhawuleza.
Ukudala ibhetri yesizukulwana esilandelayo ngamandla angaphezulu (kodwa ngaphandle kokuchasana okunyukayo), iinjineli zeTesla zenze ibhetri enkulu kakhulu enento ebizwa ngokuba yi "itafile" yoyilo eyenza mfutshane indlela yombane kwaye ngaloo ndlela inciphisa ubushushu obuveliswa kukuxhathisa. Uninzi lwale nto lunokubalelwa ekubeni ngubani onokuba ngabaphandi bebhetri ababalaseleyo emhlabeni.
Ibhetri ye-4680 yenzelwe i-tile ye-helix kwifom yokwenza lula, kunye nobukhulu bepakethi ye-46mm ububanzi kunye ne-80mm ubude. nangona kunjalo, iseli nganye ilinganiswe malunga ne-9000 mAh, nto leyo eyenza ibhetri entsha ye-Tesla flat-panel ibe yinto enhle.
Ngelixa ukonyusa ubungakanani beseli nganye kunokuba inciphe kunokubonakala ngathi kuyangqubana neemfuno zoyilo lwebhetri, ukuphuculwa komthamo wamandla kunye nolawulo olushushu lwe-4680 xa kuthelekiswa no-18650 no-2170 kubangele iiseli ezimbalwa kakhulu xa kuthelekiswa nokusebenzisa ibhetri ka-18650 kunye no-2170. Iimodeli zangaphambili zeTesla zinamandla angaphezulu kwipakethi yebhetri yobukhulu obufanayo.
Ngokombono wamanani, oku kuthetha ukuba kuphela malunga ne-960 "4680" iiseli ezifunekayo ukuba zigcwalise indawo efanayo neeseli ze-4,416 "2170", kodwa ngeenzuzo ezongezelelweyo ezifana neendleko eziphantsi zokuvelisa nge-kWh kunye nokusebenzisa i-4680 Iipakethi yebhetri yonyusa amandla kakhulu.
Njengoko kukhankanyiwe, i-4680 kulindeleke ukuba inike amaxesha ama-5 okugcinwa kwamandla kunye namaxesha e-6 amandla xa kuthelekiswa nebhetri ye-2170, eguqulela ukunyuka okulindelweyo kokuqhuba ukusuka kwi-82 kWh ukuya kwi-95 kWh kwi-Teslas Mileage entsha yonyuka ukuya kwi-16%.
Khumbula, oku zizinto ezisisiseko zeebhetri zeTesla, kukho okungakumbi emva kweteknoloji.Kodwa esi sisiqalo esihle kwinqaku elizayo, njengoko siza kufunda indlela yokulawula ukusetyenziswa kwamandla ebhetri, kunye nokulawula imiba yokhuseleko olujikelezayo. ukwenziwa kobushushu, ukulahleka kwamandla, kwaye… kunjalo… umngcipheko wokutsha kwebhetri ye-EV.
Ukuba uthanda Zonke-Izinto-Tesla, nali ithuba lakho lokuthenga i-Hot Wheels RC version yeTesla Cybertruck.
