Gorofu ngoro yebhatiri hupenyu hurefu
Ngoro dzegorofu dzakakosha pachiitiko chakanaka chegorofu. Vari kuwanawo kushandiswa kwakawanda muzvivakwa zvakakura zvakaita semapaki kana makampasi eYunivhesiti. Chinhu chakakosha chakaita kuti vataridzike zvakanyanya kushandiswa kwemabhatiri uye simba remagetsi. Izvi zvinobvumira ngoro dzegorofu kuti dzishande nekushomeka kusvibiswa kweruzha uye kuburitsa ruzha. Mabhatiri ane hupenyu hwakareba uye, kana akapfuudzwa, zvinokonzeresa kudonhedza mukushanda kwemuchina uye kuwedzera kwekugona kwekudonha uye kuchengetedza nyaya senge thermal runaways uye kuputika. Naizvozvo, vashandisi nevatengi vane hanya nekureba agorofu ngoro bhatiriinogona kugara kuitira kudzivirira njodzi uye kushandisa kugadzirisa kwakakodzera pazvinenge zvichidiwa.
Mhinduro kumubvunzo uyu zvinosuruvarisa kuti haisi diki uye zvinoenderana nezvakawanda zvinhu, imwe yacho ikemikari yebhatiri. Kazhinji, lead-asidi yegorofu bhatiri inotarisirwa kugara pakati pemakore 2-5 paavhareji mungoro dzegorofu dzinoshandiswa pachena uye makore 6-10 mune dzakavanzika. Kwenguva yakareba yehupenyu, vashandisi vanogona kushandisa mabhatiri e-lithium-ion anotarisirwa kugara anopfuura makore gumi uye kusvika makore angangoita makumi maviri emotokari dzakavanzika. Iyi nhanho inobatwa nevakawanda vamiririri uye mamiriro, zvichiita kuti kuongororwa kuwedzere kuoma. Muchinyorwa chino, tichanyura zvakadzika mune izvo zvinowanzoitika uye zvine simba zvinhu mumamiriro ezvinhu emabhatiri engoro dzegorofu, tichipa mamwe mazano pazvinogoneka.
Battery chemistry
Sezvambotaurwa, kusarudzwa kwekemikari yebhatiri inotarisisa zvakananga hupenyu hunotarisirwa huwandu hwebhatiri rengoro yegorofu rinoshandiswa.
Lead-asidhi mabhatiri ndiwo anonyanya kufarirwa, achipihwa mitengo yakaderera uye nyore kugadzirisa. Nekudaro, ivo vanopawo hudiki hunotarisirwa hurefu hwehupenyu, avhareji yemakore 2-5 kune veruzhinji ngoro dzegorofu. Aya mabhatiri anorema zvakare muhukuru uye haana kunaka kumota diki dzine simba repamusoro. Mumwe anofanirwawo kutarisa kudzika kwekubuda kana kugona kunowanikwa mumabhatiri aya, saka hazvikurudzirwe kuashandisa ari pasi pe40% yesimba rakachengetwa kudzivirira kukuvara zvachose kwe electrode.
Gel lead-acid gorufu mabhatiri engoro anotsanangurwa semhinduro kune kusakwana kwechinyakare lead-asidhi yegorofu mabhatiri. Muchiitiko ichi, electrolyte ndiyo gel panzvimbo yemvura. Izvi zvinoderedza kuburitswa uye mukana wekudonha. Zvinoda kugadziriswa zvishoma uye zvinogona kushanda mukupisa kwakanyanya, kunyanya kutonhora kwechando, izvo zvinozivikanwa kuti zvinowedzera kuparara kwebheteri uye, sechikonzero, kuderedza hupenyu.
Lithium-ion gorofu mabhatiri ndiwo anodhura zvakanyanya asi anopa hupenyu hukuru. Kazhinji, unogona kutarisira alithium-ion gorofu ngoro bhatirikugara chero pakati pemakore gumi kusvika makumi maviri zvichienderana nemaitiro ekushandisa uye zvekunze zvinhu. Izvi zvinonyanya kudzika kune electrode kuumbwa uye electrolyte inoshandiswa, zvichiita kuti bhatiri rishande uye riwedzere kusimba pakudzikisira kana iri nyaya yekuremerwa kwepamusoro, zvinodiwa zvekuchaja nekukurumidza, uye kutenderera kwekushandisa kwenguva refu.
Mamiriro ekushanda ekufungisisa
Sezvambotaurwa, bhatiri chemistry handiyo yega inotaridza yegorofu ngoro yebhatiri hupenyu. Iko, muchokwadi, kuwirirana kwekubatana pakati pebhatiri chemistry uye akawanda ekushanda mamiriro. Pazasi pane rondedzero yezvakanyanya kupesvedzera zvinhu uye mabatiro avanoita nebhatiri chemistry.
. Kuwedzeresa uye kuburitsa zvakanyanya: Kuchaja kana kuburitsa bhatiri kupfuura imwe nzvimbo yekuchaja kunogona kukuvadza zvachose ma electrode. Kuwedzeresa kunogona kuitika kana bhatiri rengoro yegorofu rikasiiwa rakareba pakuchaja. Izvi hazvisi kunyanya kunetseka munyaya yemabhatiri e-lithium-ion, apo BMS inowanzogadzirirwa kutema kubhadharisa uye kudzivirira pane zvakadai. Kuwedzera-kuburitsa, zvisinei, kushoma kubata. Iyo yekuburitsa maitiro inoenderana nemaitiro ekushandisa ngoro yegorofu uye mateki anoshandiswa. Kudzikamisa kudzika kwekuyerera kwaizodzikamisa zvakananga madaro anogona kuvharwa nengoro yegorofu pakati pekuchaja. Muchiitiko ichi, mabhatiri e-lithium-ion gorofu ane mukana sezvo achikwanisa kumira zvakadzika ekuburitsa mabhasikoro ane kushomeka kunokanganisa kana achienzaniswa nemabhatiri e-lead-acid.
. Kurumidza kuchaja uye yakakwira-simba zvinodiwa: Kuchaja nekukurumidza uye yakakwirira-simba zvinodiwa maitiro anopokana mukuchaja nekuburitsa asi achitambura kubva kune imwechete yakakosha nyaya. Kuwanda kwemazuva ano pama electrode kunogona kutungamirira mukurasikirwa kwezvinhu. Zvekare, mabhatiri e-lithium-ion gorofu anokodzera zvirinani kumhanyisa kuchaja uye yakakwira-simba rekutakura zvinodiwa. Panyaya yekushandiswa uye kuita, simba repamusoro rinogona kuwana kukwirisa kwakakwira pangoro yegorofu uye kumhanya kwepamusoro kwekushanda. Apa ndipo apo kutenderera kwekutyaira kwegorofu kunogona kukanganisa hupenyu hwebhatiri mu tandem nekushandiswa. Nemamwe manzwi, mabhatiri engoro yegorofu anoshandiswa nekumhanya kwakaderera panhandare yegorofu aipfuura mabhatiri echingoro chegorofu chechipiri anoshandiswa pakumhanya zvakanyanya panhandare imwe cheteyo.
. Mamiriro ekunze: Tembiricha yakanyanyisa inozivikanwa kuti inokanganisa hupenyu hwebhatiri. Ingave yakapakwa muzuva kana kushanda munzvimbo dzinotonhora zvakanyanya, mhedzisiro yacho inogara ichikanganisa mabhatiri engoro dzegorofu. Zvimwe zvigadziriso zvakarongwa kuderedza kukanganiswa uku. Gel Lead-Acid golf ngoro mabhatiri imwe mhinduro, sezvakambotaurwa. Imwe BMS inosumawo yakaderera kuchaja mabhatiri e-lithium-ion kuti adzise pamberi peC-rate yekuchaja kudzikamisa lithium plating.
Izvi zvinhu zvinofanirwa kuverengerwa kana uchitenga bhatiri rengoro yegorofu. Somuenzaniso, theS38105 LiFePO4 bhatiri kubva ROYPOWinonzi inogara makore gumi isati yasvika kumagumo ehupenyu. Iyi iavhareji kukosha kwakavakirwa pakuongororwa murabhoritari. Zvichienderana nemaitiro ekushandisa uye kuti mushandisi anochengeta sei bhatiri rengoro yegorofu, matenderedzwa anotarisirwa kana makore ebasa anogona kudzikira kana kuwedzera kupfuura avhareji kukosha kwakashumwa mubheteri rebheteri regorofu.
Mhedziso
Muchidimbu, hupenyu hwebhatiri rengoro yegorofu huchasiyana zvichienderana nemaitiro ekushandisa, mamiriro ekushanda, uye chemistry yebhatiri. Tichifunga maviri ekutanga akaoma kuverenga uye kufungidzira zvisati zvaitika, munhu anogona kuvimba neavhareji zviyero zvinoenderana nebhatiri chemistry. Panyaya iyi, mabhatiri e-lithium-ion gorofu anopa hupenyu hurefu asi mutengo wekutanga uchienzaniswa nehupenyu hwakaderera uye mutengo wakachipa wemabhatiri e-lead-acid.
