Musi wa5 Zvita, "Gore rinotevera, mota dzese dzevafambi muBYD dzichashandisa bhatiri remayuan matatu!" Sunungura, rega iyo matatu yuan bhatiri. BYD yakatsiva matatu-Yuan bhatiri, edza kuva anotevera remakore-kare chitoro December 5, BYD akazivisa investor ukama basa rekodhi fomu, akazivisa mashoko matatu anokosha: 1 zvachose kugadzirwa achasvika 16GWH: Kusvikira pakupera kwegore rino, BYD simba lithium The zvachose kubuda ion mabhatiri achasvika 16GWH, iyo 10GWH6G bhatiri simbi simbi lithium; 2 yakawedzera matatu yuan bhatiri fekitori: BYD ichawedzera bhatiri fekitori ine 10GWH ternary bhatiri kugadzirwa muQinghai; 3 gore rinouya, BYD Mufambi anotsiviwa nebhatiri remayuan matatu: BYD yakataura kuti PHEV itsva yekambani yakatsinhaniswa nebhatiri remayuan matatu, uye mota dzese dzevafambi dzekambani dzichashandiswa mumabhatiri matatu eyuan. Bhazi uye E6 icharamba ichishandisa lithium iron phosphate ion mabhatiri.

Kare, musi wa29 Nyamavhuvhu, BYD yakazivisa mubatanidzwa wekambani yekugadzwa kwebhatiri re lithium-ion mayuan matatu-positive material precursor project muBYD. Panyaya ye "zvisingagoneki" mumakambani emotokari epamba uye ekunze, kusarudzwa kweBYD hakusi kuchenjera. Mukuwedzera kune lithium iron phosphate kune matatu yuan, BYD inoziviswa munaNovember kuzivisa kugadziridza chimiro, iyo yakazvipira kuramba ichienderera mberi nekubatanidza simba idzva, uye kuedza kuva chitoro chemazana emakore anotevera.

Pamakore makumi maviri nematatu ekuyeukwa kwaNovember 18th, Nguva Yekukosha BYD yakavambwa. Pa "rwendo rutsva, ramangwana idzva", Wang Chuanfu akazivisa zvinangwa zvekusimudzira uye kugadzirisa mafungiro eBYD, anoda kuvaka BYD mumakore zana. Chitoro chekare, kunosvika 2025, BYD inofanirwa kuwana chiyero chetiriyoni yuan yakazara.

Nheyo yemusangano ine mapoinzi maviri anotevera: 1 yakavhurika simba lithium-ion bhatiri uye mamwe masevhisi. Kusimba kwemakwikwi eindasitiri yemagetsi matsva, kumanikidza chero kambani kuti ienderane nezvinodiwa pamusika, uye nekudaro "vertical closed production supply system" muBYD inoratidzika kunge isina kugadzikana, uye Ningde Times, iyo ichave yakanyorwa ichave BYD. Mukwikwidzi akasimba webhatiri ari BYD ari kufamba zvishoma nezvishoma akananga kunzira yekuvhura, kusimbisa kubatana nemamwe makambani.

Maererano nehuwandu, mune makumi maviri epamusoro akaiswa michina mu20 yepamusoro yekambani yebhatiri muna Gumiguru gore rino, Ningde Times (CATL) inotungamira 1083.4mWh, chikamu chemusika chiri 32.32%; BYD inokwira kubva ku490.

4MWH, 14.63% chikamu chemusika, kwete Ningde Times Hafu hafu. Kuti iparadze bhodhoro rekusimudzira, BYD haisi kungogadzirira kupatsanura bhatiri bhizinesi, zvimwe zvikamu, mota software, molds nemamwe madhipatimendi, ichashanda yakazvimirira kushanda mune ramangwana.

Munguva pfupi yapfuura, BYD Holdings Subsidiary BYD Automotive Industry Co., Ltd. yakakurudzira kambani kuti igadzire pamwe chete Shenzhen Folia Auto Parts Co.

, Ltd., kugadzira chigaro chemotokari, nezvimwe. Mukuwedzera, munaGunyana 21, gore rino, Wang Chuanfu akati patafura yenhepfenyuro yakaitirwa muShenzhen, "BYD iri kufunga nezvekupa mabhatiri kune vamwe vanogadzira mota, uye inotarisirwa kuzivisa chibvumirano chekutanga gore risati rapera.

"2 inova chitoro chemakore zana anotevera. Wang Chuanfu akati mumusangano mukuru wekambani, "BYD haisi kambani yebhatiri, kwete chete kambani yemotokari", asi nzvimbo itsva "simba idzva rekugadzirisa kwezvisikwa. Zvinoenderana nehurongwa, BYD ichavaka chimiro chesangano che "Business Boka + Division" zvinoenderana nechikamu chebhizinesi, kurima nzvimbo nyowani dzinokwira, dzinosanganisira mota dzevafambi, mota dzekutengesa, mapoka emagetsi ebhizinesi, mapoka ebhizinesi ebhatiri, makore tracks Mabhizinesi mapfumbamwe ari BYD mwenje, BYD mold, BYD mota accessories, BYD injini, BYD, Bquip yemagetsi BYD, Auto BYD Software Research Institute.

Uye vese vashandi vekuunganidza boka vakapinda muchivako chechiratidzo, vakaisa kuvandudzwa kwakanaka kwekurwiswa kwechiratidzo, uye vakapa pachena kutsaurirwa kweBYD mune itsva simba yakazara indasitiri cheni. Policy + Musika Kaviri Dhiraivha Matatu-Dynamic Lithium Ion Battery Indasitiri yakagadzikana mumusika nekudzikira kwayo tembiricha, yakakwira simba density, kubhadharisa kwakanyanya, hupenyu hwakanaka hwekutenderera. Uye parizvino marongero kana gwara, kana kugadzirwa kwekambani kwakashandurwa kune matatu yuan.

Zvinoenderana nekuronga kwenyika, 2020, iyo simba density yesimba lithium-ion bhatiri 350WH / kg, 2025 chinangwa chiri 400Wh / kg, 2030 chinangwa i500Wh / kg. Kubva gore rino, sezvo mutemo unoburitswa pabhatiri remayuan matatu, uye bhatiri remayuan matatu rinotarisirwa zvakanyanya nekuda kwekuwanda kwesimba, zvakanakira kusimba kwesimba, uye kuwedzera kwenzvimbo kwakakwira. Zvinonzi chaiyo avhareji simba density ye ternary bhatiri iri 180 ~ 190Wh / kg, iri 20% kusvika 50% zvichienzaniswa ferrite.

Asi hazvina kufuratirwa kuti matatu-yuan bhatiri chengetedzo haina kukwana. Pamusoro pekurerekera kwepamusoro-simba density yemabhatiri e-lithium-ion, kuita kwemusika wegore rino kunoitawo matatu yuan bhatiri. Zvinoenderana nekutsvaga kwekutanga, nyika yangu ine simba re lithium-ion bhatiri kugadzirwa ndeye 31GWh muzvikamu zvitatu zvekutanga zve2017.

umo NCM (nickel-cobalt manganese) inotora 49%, LZ (lithium phosphate) inotora 40%, Lithium manganese inoenderana. 8%. Izvo zvinofanirwa kucherechedzwa kuti ternary bhatiri inoreva lithium ion bhatiri inoreva chinhu chakanaka chinoshandisa lithium-cobalt-manganese acid kana nickel-cobalt olycineate.

Parizvino, kushandiswa kwakakosha kwemabhatiri e ternary ndiNCM333 uye NCM523, uye NCM622 yakapinda muhurongwa hwekugovera mamwe makambani. NCM811 iri muchikamu chebudiriro. Zvinoenderana nenhamba, iyo ternary NCM (nickel-cobalt manganese) parizvino iri 333, 523, 622, 811 modhi ina.

Iyo yakakwirira nickel yezvinhu zvakakosha zvinoshanda, iyo inonyanya kukosha yebhatiri: bhatiri rakasimba rakafanana nemhumhi seyazvino Pakuona, dambudziko guru rekumanikidzira rematatu-yuan system ndeyekuchengetedza. Kana dambudziko rekuchengetedza ragadziriswa, sezvo iyo yakanyanya kukura yakanaka zvinhu zvesimba density ndeyechisikigo uye musika wazvino, iyo nzira-nhatu system ichave yakareba kwenguva yakareba. Kutonga pabasa.

Mukuita kwemusika wakabatanidzwa, yakakwira-nickel yakaderera cobalt ichava nzira yekusimudzira yeramangwana matatu-yuan bhatiri. Nekudaro, iyo lithium iron phosphate ine kuchengetedzwa kwakanyanya, hupfumi hwakapfuma zviwanikwa, uye mutengo wemutengo unonetsa kuenderana, uye munguva pfupi, kutsiva kwemayuan matatu pa lithium iron phosphate hakuratidzwe munguva pfupi, uye iron phosphate Lithium zvakare ine hombe-inogoneka musika mukuchengetedza simba. Kunyangwe izvo zviviri zvine mukana, izvo zvinokanganisa zvichiri nguva, pakugadzirisa matambudziko aya, iyo itsva simba lithium-ion bhatiri tekinoroji nzira ichazvarwa mumhepo, uye yakasimba-state lithium-ion bhatiri inotarisirwa kuve chizvarwa chinotevera.

Yakakwira simba density simba uye simba rekuchengetedza bhatiri tekinoroji yave kubvumirana kweacademia neindasitiri. Uye Toyota, Japanese Battery Factory TDK, Samsung SDI, LG Chemical, ATL, etc., musimba, yakasimba nyika, kutanga kubva gore rinouya, solid-state bhatiri ichaiswa kudhijitari nemamwe minda, 2019-2020, zvishoma nezvishoma ichaita chiyero.
