Tsananguro yakadzama ye18650 bhatiri uye 21700 bhatiri pfungwa uye zvakanakira

Nekukurumidza kuvandudzwa kwemotokari nyowani dzesimba mumakore achangopfuura, mabhatiri e lithium avewo akakurumbira. Mabhatiri emagetsi agara ari munda unokosha wemotokari itsva dzemagetsi. Ani nani ane hunyanzvi hwemabhatiri emagetsi achagona mota dzemagetsi matsva. Pakati pemabhatiri emagetsi, iyo inonyanya kubata maziso pasina mubvunzo ndeye lithium-ion bhatiri.

Simba remagetsi emabhatiri e-lithium-ion akakwirira zvikuru, uye simba rayo rinosvika 1.5 kusvika ku2 nguva dzemabhatiri e-nickel-hydrogen ehuremu hwakafanana, uye ine mwero wakaderera kwazvo wekuzviburitsa. Mukuwedzera, mabhatiri e-lithium-ion anenge asina “memory effect” uye haana zvinhu zvine chepfu. Aya mabhenefiti e-lithium-ion mabhatiri anoita kuti ishandiswe zvakanyanya mumunda wemagetsi matsva.

Mazuvano, iyo inonyanya kushandiswa cylindrical lithium-ion mabhatiri ndeye 18650 mabhatiri uye 21700 mabhatiri.

18650 bhatiri:

18650 mabhatiri pakutanga aireva nickel-metal hydride mabhatiri uye lithium-ion mabhatiri. Sezvo nickel-metal hydride mabhatiri ikozvino asisashandiswe, ivo zvino vanotaura nezve lithium-ion mabhatiri. 18650 ndiye akatanga mabhatiri e-lithium-ion-yakajairwa lithium-ion bhatiri modhi yakaiswa neSONY kuJapan kuitira kuchengetedza mari, apo 18 inoreva dhayamita ye18mm, 65 inoreva kureba kwe65mm, uye 0 inoreva cylindrical bhatiri. Akajairika mabhatiri e18650 anosanganisira ternary lithium-ion mabhatiri uye lithium iron phosphate mabhatiri.

Kutaura nezve 18650 mabhatiri, Tesla inofanirwa kutaurwa. Apo Tesla iri kugadzira mabhatiri emotokari yemagetsi, yakaedza marudzi akawanda emabhatiri, asi pakupedzisira yakatarisa mabhatiri e18650 uye yakashandisa mabhatiri e18650 semagetsi matsva emagetsi emotokari. Technical nzira. Zvinogona kutaurwa kuti chikonzero nei Tesla achikwanisa kuve nekuita kusiri kwakaderera kune echinyakare mota dzemafuta, mukuwedzera kune yemagetsi mota tekinoroji, zvakare inobatsira kubva kuTesla’s advanced bhatiri tekinoroji. Saka nei Tesla akasarudza bhatiri re18650 sesosi yayo yesimba?

Advantage

Yakakura tekinoroji uye yakakwirira kuenderana

Asati apinda mumunda wemotokari itsva dzemagetsi, mabhatiri e18650 akashandiswa zvakanyanya muzvigadzirwa zvemagetsi. Ndivo vekutanga, vakakura uye vakagadzikana zvakanyanya lithium-ion mabhatiri. Mushure memakore eruzivo, vagadziri veJapan vakaunganidza 18650 mabhatiri mune zvigadzirwa zvevatengi. Tekinoroji yepamusoro inoshandiswa zvakanyanya mumunda wemabhatiri emotokari. Panasonic ndeimwe yepasirese yakakura kwazvo bhatiri tekinoroji uye zviyero makambani. Kuenzaniswa nevamwe vanogadzira, ine mashoma echigadzirwa chakakanganisika uye yakakura chiyero, uye zvakare zviri nyore kusarudza mabhatiri nekuenderana kwakanaka.

Mukupesana, mamwe mabhatiri, akadai akaturikidzana lithium-ion mabhatiri, ari kure nekukura zvakakwana. Zvigadzirwa zvakawanda hazvigone kubatanidzwa muhukuru uye saizi, uye maitiro ekugadzira ane vagadziri vemabhatiri haagone kusangana nemamiriro acho. Kazhinji, kuwirirana kwebhatiri hakusviki pamwero we18650 bhatiri. Kana kuwirirana kwebhatiri kusingakwanisi kuita zvinodiwa, kutungamirirwa kwenhamba yakawanda yebhatiri tambo uye bhatiri mapaketi akaumbwa akafanana haabvumiri kushanda kwebhatiri rimwe nerimwe kuti riitwe zviri nani, uye mabhatiri 18650 anogona kugadzirisa dambudziko iri zvakanaka.

High chengetedzo kuita

Iyo 18650 lithium bhatiri ine yakakwirira kuchengetedza kushanda, isingaputike, isingabatike; isina-chepfu, isingasvibise, uye yapasa RoHS trademark certification; uye ine yakanaka yakakwirira tembiricha kuramba, uye kuburitsa kushanda zvakanaka kuri 100% pa65 madhigirii.

Bhatiri re18650 rinowanzoiswa muhombodo yesimbi. Mumamiriro ezvinhu akanyanyisa akadai sekudhumhana kwemotokari, inogona kuderedza kuitika kwenjodzi dzekuchengetedza zvakanyanya sezvinobvira, uye kuchengetedzwa kwakakwirira. Mukuwedzera, saizi yebhatiri yesero ye18650 idiki, uye simba resero rega rega rinogona kudzorwa mune diki renji. Kuenzaniswa nekushandiswa kwemasero makuru ebheteri, kunyange kana chikwata chebheteri pack chikakundikana, chinogona kuderedzwa Kukanganisa kwekukundikana.

Yakanyanya simba density

Kugona kwe18650 lithium bhatiri kazhinji kuri pakati pe1200mah ne3600mah, nepo huwandu hwebhatiri hunenge huchingoita 800mah. Kana yakasanganiswa kuita 18650 lithium bhatiri pack, iyo 18650 lithium bhatiri paki inogona kudarika 5000mah. Kugona kwayo kunosvika 1.5 kusvika ka2 pane yebhatiri renickel-hydrogen rehuremu hwakafanana, uye ine mwero wakaderera kwazvo wekuzviburitsa. Iyo simba density ye18650 bhatiri sero parizvino inogona kusvika padanho re250Wh/kg, iyo inosangana nezvinodiwa zveTesla’s high cruising range.

Mutengo wakaderera uye wakakwira mutengo kuita

Iyo 18650 lithium bhatiri ine hupenyu hurefu hwesevhisi, uye hupenyu hwekutenderera hunogona kusvika kanopfuura ka500 mukushandiswa kwakajairwa, iyo inodarika kaviri iyo yemabhatiri akajairwa. Iyo 18650 chigadzirwa chine yakakwira dhigirii rekukura kwetekinoroji. Iyo dhizaini yekugadzira, tekinoroji yekugadzira, uye midziyo yekugadzira, pamwe neyakatorwa 18650 module tekinoroji zvese zvakakura, izvo zvese zvinoderedza mari yekushandisa nekugadzirisa.

Bhatiri re18650, iro riri kushandiswa zvakanyanya, rine nhoroondo yebudiriro kwemakore mazhinji. Kunyangwe tekinoroji yakura kana ichienzaniswa nemamwe marudzi emabhatiri, ichiri kutarisana nematambudziko akadai sekugadzira kupisa kwakanyanya, kuunganidzwa kwakaomarara, uye kusakwanisa kuwana nekukurumidza kuchaja. Muchirevo chechinyorwa chino, 21700 cylindrical ternary mabhatiri akavapo.

Musi waNdira 4, 2017, Tesla akazivisa kutanga kwekugadzirwa kwakawanda kwebhatiri idzva re21700 rakabatana rakagadzirwa naTesla nePanasonic, uye akasimbisa kuti iri ibhatiri rine huwandu hwesimba repamusoro uye mutengo wakaderera pakati pemabhatiri aripo pari zvino kugadzirwa kwakawanda.

21700 bhatiri:

Bhatiri 21700 imhando yebhatiri ye cylindrical, kunyanya: 21-inoreva bhatiri ye cylindrical ine dhayamita yekunze ye21mm; 700-inoreva cylindrical bhatiri ine hurefu hwe70.0mm.

Iyi ndiyo modhi itsva yakagadziridzwa kuti isangane nezvinodiwa zvemotokari dzemagetsi kwenguva refu yekutyaira mileage uye kuvandudza mashandisirwo anobudirira enzvimbo yebhatiri remotokari. Kuenzaniswa neyakajairwa 18650 cylindrical lithium bhatiri, huwandu hwe21700 hunogona kudarika 35% yakakwirira kupfuura iyo yezvinhu zvakafanana.

Iyo 21700 nyowani ine mana akakosha mabhenefiti:

(1) Iyo bhatiri cell cell inowedzerwa ne35%. Tora 21700 bhatiri rakagadzirwa naTesla semuenzaniso. Mushure mekuchinja kubva ku18650 modhi kuenda ku21700 modhi, iyo bhatiri cell cell inogona kusvika 3 kusvika 4.8 Ah, yakakura kuwedzera kwe35%.

(2) Iyo simba density yebhatiri system inowedzerwa ne20%. Zvinoenderana nedata rakaburitswa naTesla, simba remagetsi reiyo 18650 bhatiri system yakashandiswa mumazuva ekutanga yaive ingangoita 250Wh/kg. Gare gare, kuwanda kwesimba kwe21700 bhatiri system yakagadzirwa nayo yaive ye300Wh/kg. Iyo volumetric simba density ye21700 bhatiri yaive yakakwira kupfuura yekutanga 18650. Inosvika 20%.

(3) Mutengo weiyo system unotarisirwa kudonha neinenge 9%. Kubva pakuongororwa kweruzivo rwemari yebhatiri yakaziviswa naTesla, iyo simba lithium bhatiri system ye21700 bhatiri inotengeswa pamadhora zana nemakumi manomwe / Wh, uye mutengo we170 bhatiri system i18650 / Wh. Mushure mekushandisa mabhatiri e185 paModel 21700, mutengo webhatiri system chete unogona kuderedzwa ne3%.

(4) Huremu hwehurongwa hunotarisirwa kudonha neinenge 10%. Iyo yakazara vhoriyamu ye21700 yakakura kupfuura 18650. Sezvo huwandu hwemonomeri hunowedzera, huwandu hwesimba hwemonomer hwakakwirira, saka huwandu hwebhatiri monomers hunodiwa pasi pesimba rimwechete hunogona kuderedzwa neanenge 1/3, izvo zvinoderedza kuoma. ye system management uye kuderedza huwandu hwemabhatiri. Nhamba yezvikamu zvesimbi uye zvigadzirwa zvemagetsi zvinoshandiswa mubhegi zvinowedzera kuderedza huremu hwebhatiri. Mushure mekunge Samsung SDI ichichinjira kune seti nyowani yemabhatiri e21700, zvakaonekwa kuti huremu hwehurongwa hwakaderedzwa negumi muzana kana zvichienzaniswa nebhatiri razvino.
