Dhata inoratidza kuti mumwedzi mina yekutanga yegore rino, kutumirwa kwesimbi phosphate uye iron phosphate kwakawedzera zvichienzaniswa nenguva yakafanana gore rapfuura. Pakati pavo, vhoriyamu yekutakura yelithium iron phosphate mabhatiri ndeye 2.6Gwh, uye huwandu hwekutakura hweternary lithium mabhatiri hwakakwira se771.51MWh.

Pamusoro pezvo, mwero wekupinda kwezvinhu zveternary zvemotokari dzakakosha muna 2015 waive 61%, uye kudiwa kwakasvika 1.1GWh. Muna 2016, chiyero chekupinda chichasvika 65%, uye chido chichava 2.9Gwh; panosvika 2020, mwero wekupinda uchasvika 80%, uye kudiwa kwemusika kuchave 14.0Gwh.

Zvinogona kuoneka kuti ternary zvinhu uye lithium iron phosphate zvishoma nezvishoma zviri kutora mainstream mukushandiswa kwemagetsi emagetsi emagetsi akachena mota, uye chikamu cheternary zvinhu chinova chakakura uye chikuru. Nekudaro, iyo nzira yehunyanzvi iyo yakachena yemagetsi Logistics mota ichatora mune ramangwana haibvi chete pane tekinoroji uye mhando yemagetsi lithium mabhatiri, asiwo pamusika kudiwa uye manejimendi matanho.

Chekutanga, nei zvinhu zvitatu zvichitora mota dzakachena dzemagetsi zvinhu?

MuChina, pakati pemotokari dzakachena dzemagetsi, ternary lithium bhatiri tekinoroji ndiyo inonyanya kushandiswa nzira, inoteverwa ne lithium iron phosphate mabhatiri. Ehe, kune imwechete yehunyanzvi nzira, iyo parameter yesimba lithium mabhatiri akagadzirwa nevagadziri vakasiyana-siyana haana kufanana. Semuyenzaniso, Tesla neLG vanoshandisa ternary zvinhu uye vane ma parameter akasiyana maererano nemhando yebhatiri, huwandu hwebhatiri, hupenyu hwekutenderera, uye bhatiri pack simba density. Uye mamwe ma paramita anogara achichinja nekuenderera mberi kwekusimudzira tekinoroji. Mazhinji ma parameter ndiwo akakwana kukosha.

Pano tinofananidza zvakanakira uye zvakaipira zvakasiyana-siyana simba lithium bhatiri cathode zvinhu kuti tipindure mubvunzo wekuti sei zvinhu zvitatu izvi zviri izvo zvinonyanya kuitika mumotokari dzekutakura.

Kuongorora kwakadzama kwezvikonzero zvitanhatu nei mabhatiri makuru matatu achigara pamusika mukuru wemotokari dzakachena dzemagetsi.

Kuongorora kwakadzama kwezvikonzero zvitanhatu nei mabhatiri makuru matatu achigara pamusika mukuru wemotokari dzakachena dzemagetsi.

Kutanga, zvinogona kuonekwa kubva pamufananidzo kuti kunyange kana kuchengetedzwa kwezvinhu zve ternary kusina kukwirira, makambani akawanda emotokari yemotokari anozviona zvakakwana, kana kuti achatora ternary lithium bhatiri tekinoroji nzira, ine yakakwira cruising range, hombe chaiyo inokwana. , hupenyu hurefu hwebasa, nezvimwewo mukana.

Kechipiri, mileage yemotokari yakachena yemagetsi inobata mamiriro ekushanda uye kugona kwemotokari zvinhu. Kune mota dzakachena dzemagetsi ekutakura zvinhu, chakakosha ndiko kupera kwezvinhu kugovera, kutakurwa kwemadhorobha, dzimba uye mamwe misika. Izvo zvinodiwa kuti ive nechokwadi chekuti basa rekufambisa rapedzwa mukati mezuva rimwe, kunyanya panguva dzepamusoro senge Double Eleven, uye rwendo rwakakura. Nhamba yehuwandu hunoenderana nehuwandu hwemabhatiri uye kufananidzwa kwesimba rekupa simba.

Chechitatu, pari zvino, rubatsiro rwehurumende rwuri kubviswa, uye mari yeminda iri kuramba ichidzikira. Munzvimbo dzakawanda, rubatsiro rwakaderera se400 yuan pakilowatt awa. Semuyenzaniso, muJiangsu neHangzhou, vamwe vafambisi vemotokari vemagetsi vakachena vakati rubatsiro rwakaderera zvakadaro , Haikwanise kutamba. Kune makambani emotokari, zvine musoro kutsvaga nzira yehunyanzvi inodhura. Mutengo wemotokari lithium mabhatiri ndiyo yakakwira. Parizvino, rubatsiro munzvimbo zhinji dzakafambiswa nekambani, uye tekinoroji yekugadzira mota yekugadzira haina kukwira sedzimwe mota. Mutengo we ternary lithium bhatiri yakaderera pane iyo yelithium iron phosphate bhatiri, uye zvinodiwa zvehunyanzvi hazvina kukwirira seye lithium iron phosphate bhatiri. Izvi zvinochengetedza zvakanyanya hupfumi hwemagariro uye mari yekugadzira. Chechina, chimwe chezvitsitsinho zvakakura zveAchilles zve lithium iron phosphate ndiko kuderera kwekushisa kwekushisa, kunyange kana nano uye carbon coatings zvisingagadziri dambudziko iri. Zvidzidzo zvakaratidza kuti bhatiri ine simba re 3500mAh, kana ikashanda pa -10 ° C, mushure mepasi pe100 yekuchaja-kubvisa mitsetse, simba rayo richakurumidza kuora kusvika ku500mAh uye rinobva raputswa. Iyo ternary zvinhu ine yakanaka yakaderera tembiricha kuita, uye iyo pamwedzi attenuation ndeye 1 kusvika 2%. Pakupisa kwakadzika, chiyero chayo chekuderera hachisi chakakwirira se lithium iron phosphate.

Chechishanu, zvinhu zveterpolymer zvinogara zvakanyanya, zvakanyanya nekuda kwesimba remakambani emotokari ekunze. Iyo yakawanda yemagetsi matsva emagetsi emakambani ekunze emotokari anoshandisa ternary lithium mabhatiri, mazhinji ayo ari 18650 maseru. Zvinogonawo kuonekwa kubva ku286 batch yezviziviso zvemotokari itsva kuti ruzhinji rwemotokari dzakachena dzemagetsi dzinoshandisa 18650 ternary lithium mabhatiri. Iyo imwe-nhanho yezita remagetsi inowanzo 3.6V kana 3.7V; iyo shoma yekubvisa yekumisa voltage kazhinji ndeye 2.5-2.75V. Iyo yakajairika huwandu ndeye 1200 ~ 3300mAh. 18650 bhatiri, asi kuwirirana kwakanaka kwazvo; iyo yakaturikidzana bhatiri inogona kuitwa yakakura (20Ah kusvika 60Ah), iyo inogona kuderedza kuwanda kwemabhatiri, asi kuwirirana hakuna kunaka. Kusiyana neizvi, panguva ino, zvakaoma kuti vatengesi vebhatiri vaise mari yakawanda yevashandi uye zviwanikwa zvekuvandudza maitiro ekugadzira mabhatiri akaturikidzana.

(2) Chimiro uye saizi, nekuti iwo matatu makuru marudzi akasiyana, pane misiyano, uye saizi yemhando imwe chete yakasiyana. Kune marudzi matatu emabhatiri e ternary, imwe bhatiri rakapfava, senge A123, Vientiane, uye polyfluorine. Imwe ibhatiri recylindrical, sezvakaita Tesla. Kune zvakare masikweya akaoma-shell mabhatiri, akadai seBYD uye Samsung. Pakati pemafomu matatu, mutengo wekugadzira wematehwe akaomarara wakakwira, uchiteverwa nemabhegi akapfava, uye pakupedzisira masilinda. Imwe maonero ndeokuti kuchengetedzwa kwebhegi rakapfava kwakakwirira kudarika iyo cylinder, uye chimiro che cylinder chinoita kuti zvive zvakaoma kugadzirisa zvachose dambudziko rekuchengetedza. Parizvino, akawanda ternary bhatiri akapfava ekurongedza matekinoroji akaiswa mumotokari dzenyika yangu. Nekudaro, izvo zvinodiwa zvehunyanzvi zvekuchinjika kurongedza zvakati wandei, kunyanya kurongedza tekinoroji. Kusarongedza kwakashata kunokonzeresa matambudziko akadai sebulging uye kuvuza, uye kukonzera njodzi dzekuchengetedza. Mune mamwe mazwi, kushandiswa kwemabhatiri e-ternary kunobva pamakona esimbi mashefu. Iyo sikweya simbi shell ine zvakanakira kumira, kurongedza kwakapusa, uye yakakwirira chaiyo simba. Izvo zvakashata zvakare ndezvekuti kupisa kwekupisa mhedzisiro hakuna kunaka.

3. Simba lithium bhatiri marongerwo

Kurongeka kwesimba relithium bhatiri kunofanirwa kurongeka zvinoenderana nechassis yemotokari yakachena yemagetsi zvinhu, tichifunga nezve huremu hwemuviri uye zvimwe zvinhu, kazhinji muhuro yemotokari, zvinoenderana nemhando dzakasiyana dzemagetsi akachena. logistics motokari. Semuenzaniso, marori nemarori madiki akarongwa zvakasiyana. Muchidimbu: 1. Zvakakosha kufunga nezvekugadzirisa nzvimbo ye simba lithium mabhatiri. 2. Mutoro chii? Kutakura motokari. 4 kuenzanisa. Panofanira kuva nezvimwe zvinodiwa pakupisa kupisa. Gutisa iyo yakaderera pasi clearance, longitudinal passing angle uye zvimwe passability zvinodiwa. Sangana nezvinodiwa zvinoenderera mberi zvekudyidzana kwevanhu-kombuta. Inofanirwa kutevedzera mitemo yekudhumhana kwenyika. Ane imwe nhanho yekuisa chisimbiso zvinodiwa. Iva nechokwadi chekudiwa kwemagetsi epamusoro-voltage.

Mukuwedzera, kurongeka kwesimba lithium bhatiri inofanirawo kufunga nezvekuchengetedzwa kwemutyairi. Kana yakarongedzwa pasi pechigaro, kana bhatiri richibata moto, achangoburwa ndiye mutyairi. Kana iwe ukashongedza pasi pengoro, chinhu chekutanga chinounza njodzi ndicho kutakura, uye mutyairi ane mukana mukuru wokutiza.
