Pakutanga kwekutanga kwemaitiro matsva emagetsi, vamwe vatengi vakaratidza kunetseka kwavo. Kana bhatiri rakaputsika, ndinofanira kushandisa hafu yemari kuti nditsive iyo, iyo inopfuura mari yose yemotokari dzangu dzose. Ndizvo zvazviri chaizvo here? Nhasi ini ndichakupa ongororo kubva kune technical point yekuona.

Parizvino pane maviri makuru mapoka ezvigadzirwa pamusika: lithium iron phosphate uye ternary lithium. Pakati pavo, zvakanakira iron phosphate inomiririrwa neBYD hupenyu hurefu uye kuchengetedzwa kuri nani; zvakanakira kushandiswa zvakanyanya mumotokari dzakachena dzemagetsi zviri nani kudzika-tembiricha kuita uye yakakwirira capacitance pavhoriyamu yeyuniti.

Maererano nemitemo yenyika, kana simba remotokari yemagetsi rakaderedzwa kusvika ku80% yebhatiri itsva yenyika, haina kukodzera kuenderera mberi kushandiswa mumotokari yemagetsi; panenge pa70%, bhatiri paki rinofanira kubviswa. Zvinoenderana neazvino bhatiri tekinoroji, huwandu hweternary lithium bhatiri inoora kusvika 80% mushure me500-1000 yekuchaja mabhatiri, ukuwo simba re lithium iron phosphate mabhatiri anoora kusvika 80% mushure me2000 kuchaja kutenderera.

Tora Tesla model3 semuenzaniso. Rine madingindira ezvinozvino. Iyo yakachipa yakachipa refu-yakare dhiraivha yekumashure yeBazi reIndasitiri uye Ruzivo rweTekinoroji ine mileage yakazara yemakiromita mazana matanhatu. Yakaverengerwa pa600%, inogona kufamba makiromita mazana mana nemakumi masere pamubhadharo mumwe chete. Zvinoenderana nehuwandu hudiki hwekuchajisa ternary lithium bhatiri ka80, bhatiri paki rinogona kumhanya kwemakiromita mazana maviri nemakumi mana pasina matambudziko. Tisingatauri 480 recharges.

Imota ipi yakatengwa kunze kwenyika inodhura zvakanyanya? Ngatiise parutivi iyo inotengeswa kunze modhi, inonyanya kufarirwa neBYD Yuan EV360 muna Ndira semuenzaniso, Bazi reIndasitiri uye Ruzivo rweTekinoroji rine huwandu hwakakwana hwemakiromita 305, 80% kuverenga, kubhadharisa kuchamhanya makiromita angangoita 244, maererano. 500 Iyo yakaderera yekuchaja nguva yemabhatiri matatu e-lithium pagore inoverengerwa zvichienderana nehuwandu hwe1,000 recharges. Inoda kufamba makiromita 244,000 kuti isvike kuhupenyu hwebhatiri.

Kutora chero yakajairwa compact mota uye SUV modhi nemutengo ungangoita 150,000, iyo indasitiri uye yese-kutenderera basic yasvika anopfuura 400 makiromita, ayo ari 80%, uye mutengo unogona kuverengerwa angangoita 320 makiromita. Nguva yekuchaja yeternary lithium bhatiri ndiyo yakaderera. Iyo shoma mileage ye500 nguva inogona kufamba 160,000 makiromita. Kana dziri idzo mota dzemagetsi dzakachena dzakashongedzerwa lithium iron phosphate bhatiri packs, usazvinetse zvakanyanya. Kunyangwe iyo yakazara mileage iri mazana maviri emakiromita chete, 200 recharges inokwana kukufambisa iwe 2,000 makiromita.

Kazhinji, kana iwe uchienda kubva kubasa makumi mashoma emakiromita pazuva, kutenga motokari itsva ine yakazara mileage yemakiromita 300 inogona kukubvumira kuti uishandise kwemakore anopfuura 10 pasina dambudziko. Zvechokwadi, iyo yakareba mileage, zviri nani, asi zvinonyanya kukosha, hutano hutsika hwekutyaira. Pano, mupepeti anokupa mamwe mazano.

Shallow charge and shallow discharge Teerera kudziya kwebhatiri

Zvinoenderana nekurudziro yemugadziri, bhatiri paki rekushandisa SOC hwindo i10% -90%. Zvichitaurwa zviri nyore, ndiko kudzivirira kuchaja bhatiri risati rafa. Panguva imwecheteyo, zvinokurudzirwa kubhadharisa kusvika ku80-90% nguva imwe neimwe kudzivirira kuwedzera kwebhatiri.

Pamusoro pezvo, kana zvichibvira, edza kushandisa imba inononoka kuchaja kuti uderedze huwandu hwekuchaja nekukurumidza. Mushure mezvose, kazhinji kumhanyisa-kumhanya uye kukwira-tembiricha kuchaja uye kuburitsa kuchakanganisa zvakanyanya hupenyu hwebhatiri. Semuenzaniso, kana iri kure-kure kutyaira kwemotokari yemagetsi, tembiricha yemukati yakakwira zvakanyanya nekuti bhatiri iri munzvimbo yekubuda-kumhanya uye DC inochaja kwenguva yakareba. Kana pasina yakanaka tembiricha control management system, zvinogona kuita kuti bhatiri riwedzere kupisa uye kukonzera kupisa kwega. Naizvozvo, mota dzemazuva ano dzakachena dzemagetsi dzinowanzo kuve dzakashongedzerwa nehungwaru yekudzora tembiricha system, izvo zvakakosha kuti utenge mota. Parizvino, hydrometallurgical tekinoroji yakakosha kushandiswa kwesimbi kudzoreredza mumarara lithium mabhatiri munyika yangu. Iyo yakanaka uye cathode inoshanda zvinhu zvinopatsanurwa ne organic solvents, uye iyo simbi cobalt inodzoserwa nenzira dzakadai sekubvisa, kunaya, electrolysis, uye biology. Gongyi Xianwei Machinery Equipment Co., Ltd. yakatsvaga uye yakagadzira mhando nyowani yelithium bhatiri yakanaka electrode pepa rekupwanya uye recycling michina, iyo inotora yakaoma mechani yekuparadzanisa nzira. Mukuona kwekunyanya kweiyo yakaipa electrode zvinhu, inogadzika yakapwanyika uye yakaparadzaniswa. , Kudzokororwa kwesimbi yealuminium, kunhuwa kunowanikwa kuburikidza nemhute yemvura activated kabhoni, uye huruva inounganidzwa kuburikidza nemidziyo yekubvisa huruva. Inogona kunyatso dzokorora zvinhu zvakakosha zvesimbi mumabhatiri e-lithium uye kudzivirira kutambisa zviwanikwa uye maitiro anotevera ekugadzirisa. Iyo lithium bhatiri ine yakatanhamara mashandiro mukuita midziyo yeyakanaka electrode sheet. Inonyatsoona kuti iyo yakaipa electrode zvinhu zvemarara lithium bhatiri imhangura uye graphite, uye kubviswa uye kuparadzaniswa kwe lithium aluminium cobaltate ine chiyero chekuparadzanisa kupfuura 99%. Iyo parizvino tekinoroji yepamberi yekugadzirisa tsvina yelithium mabhatiri muChina. Iyo kambani yakagadzira mutsara wekugadzira 500-1000kg paawa, iyo yakarumbidzwa zvakanyanya neruzhinji rwevashandisi. Nokudaro, kurapwa uye kuraswa kwemarara isayenzi uye inobudirira lithium bhatiri, iyo isina kungova nemigumisiro yakakosha yezvakatipoteredza, asiwo ine zvikomborero zvakanaka zvehupfumi, kuitira kuti kubudiswa kweguruva re lithium battery anode kunosvika kune imwe nyika emission standard isati yabudiswa pa. high altitude, uye panguva imwe chete anoona kuitika kweasina-ferrous simbi. Kupatsanurwa kunoshanda uye kudzokororwazve kwemabhatiri e-lithium kwakagadzirisa gaka mukurapa kwesainzi kwemarara lithium mabhatiri muindasitiri, uye yakawedzera hunyanzvi kune chikonzero chekuchengetedza kwezvakatipoteredza. Kuenzaniswa nekunyorova kwekupwanya, kuomeswa kwemagetsi kunogona kuita kuti zvinhu zvinoshanda zvive nyore kupatsanura kubva kune inounganidza mvura, nekudaro ichidzikisa kusachena kwemukati mezvigadzirwa zvakapwanyika, uye nyore kupatsanura uye kudzoreredza zvinhu zvinotevera. Naizvozvo, kuvandudzwa kwemidziyo yakasvibira yekudzokorodza kwegasi rakasvibiswa munzvimbo yakaoma yekupwanya mabhatiri e-lithium, uye kutonga uye shanduko yekusvibiswa kwechipiri panguva yekugadziriswa kwemaitiro ekudzokorodza kune zvakati wandei kwezvakatipoteredza, zvehupfumi uye zvemagariro mabhenefiti. Iye zvino, Gongyi Ruisec Machinery Equipment Co., Ltd.

Kune mota dzemagetsi dzakasanganiswa (PHEV), hupenyu hwebhatiri hwakareba. Mushure mezvose, bhatiri paki rine injini yekupa simba kana bhatiri rafa. Mota dzakajairwa dzakasanganiswa dzinongotsigira AC inononoka kuchaja, iyo inoderedza zvakanyanya tembiricha yakakonzerwa nekuchaja bhatiri uye kubuda. Ndokusaka vagadziri vemotokari vachiwanda vachigadzira mota dzakasanganiswa.

Pakave pasina budiriro yakakura muhunyanzvi hwemagetsi tekinoroji kusvika nhasi, uye mota dzemagetsi dzakachena dzakanyanya kukodzera kutyaira mumadhorobha. Kunyangwe dzimwe nguva kutyaira kwenguva yakareba kamwe kana kaviri hakuzove nekukanganisa kwakakosha pabhatiri, nekufamba kwenguva, zvinonyatso dzikisa hupenyu hwebhatiri. Pamusoro pezvo, kana uchitenga mota yemagetsi yakachena, zvakakosha kuti utarise kune rwendo rwekufamba uye kana paine yakangwara tembiricha yekudzora system.
