Ngoku, ungcoliseko lwehlabathi luyanda umhla nezolo.Ukukhutshwa kombhobho ophuma kwizithuthi zemveli zamafutha kubangele ungcoliseko lomoya kwaye kwandise ukukhutshwa kwerhasi yegreenhouse yehlabathi.Ukugcinwa kwamandla kunye nokunciphisa ukukhutshwa kwezinto ezikhutshwayo kube ngumba ophambili oxhalabisa uluntu lwamazwe ngamazwe (HVCH).Izithuthi zamandla amatsha zithatha isabelo esikhulu kwintengiso yeemoto ngenxa yokusebenza kwazo okuphezulu, ukucoceka kunye nokungangcolisi amandla ombane.Njengomthombo wamandla oyintloko wezithuthi zombane ezicocekileyo, iibhetri ze-lithium-ion zisetyenziswa ngokubanzi ngenxa yamandla abo aphezulu kunye nobomi obude.
I-Lithium-ion iya kuvelisa ubushushu obuninzi kwinkqubo yokusebenza kunye nokukhupha, kwaye oku kufudumala kuya kuchaphazela kakhulu ukusebenza kunye nobomi bebhetri ye-lithium-ion.Ubushushu obusebenzayo bebhetri ye-lithium yi-0 ~ 50 ℃, kwaye iqondo lokushisa elihle kakhulu liyi-20 ~ 40 ℃.Ukuqokelelwa kobushushu bebhetri engaphezulu kwe-50 ℃ kuya kubuchaphazela ngqo ubomi bebhetri, kwaye xa ubushushu bebhetri bungaphezulu kwe-80 ℃, ipakethi yebhetri inokudubula.
Ugxininiso kulawulo lwe-thermal yeebhetri, eli phepha lishwankathela iteknoloji yokupholisa kunye nokushisa ukushisa kweebhetri ze-lithium-ion kwimeko yokusebenza ngokudibanisa iindlela ezahlukeneyo zokutshatyalaliswa kobushushu kunye nobuchwepheshe ekhaya nakwamanye amazwe.Ugxininiso ekupholiseni komoya, ukupholisa ulwelo, kunye nokupholisa kokutshintsha kwesigaba, inkqubela phambili yeteknoloji yokupholisa ibhetri yangoku kunye nobunzima bangoku bophuhliso lobugcisa bulungiswa, kunye nezihloko zophando lwexesha elizayo kulawulo lobushushu bebhetri ziyacetywa.
Ukupholisa umoya
Ukupholisa komoya kukugcina ibhetri kwindawo yokusebenza kunye nokutshintshana kobushushu emoyeni, ingakumbi kubandakanywa ukupholisa umoya ngenkani (Isifudumezi somoya se-PTC) kunye nomoya wendalo.Iinzuzo zokupholisa umoya ziindleko eziphantsi, ukuguquguquka okubanzi, kunye nokhuseleko oluphezulu.Nangona kunjalo, kwiipakethi zebhetri ye-lithium-ion, ukupholisa umoya kunokusebenza okuphantsi kokutshintshwa kobushushu kwaye kulungele ukusabalalisa ubushushu obungalinganiyo bepakethi yebhetri, oko kukuthi, ukufana kweqondo lokushisa.Ukupholisa komoya kunemida ethile ngenxa yomthamo ophantsi wobushushu obukhethekileyo, ngoko ke kufuneka kuxhotyiswe nezinye iindlela zokupholisa ngaxeshanye.Isiphumo sokupholisa sokupholisa komoya sinxulumene ikakhulu nolungiselelo lwebhetri kunye nommandla woqhagamshelwano phakathi komjelo wokuhamba komoya kunye nebhetri.I-parallel air-cooled ibhetri yolawulo lwe-thermal system iphucula ukusebenza kakuhle kokupholisa kwenkqubo ngokuguqula ukusabalalisa kwesithuba sebhetri kwipakethi yebhetri kwi-parallel air-cooled system.
ukupholisa ulwelo
Impembelelo yenani leembaleki kunye nesantya sokuhamba kwisiphumo sokupholisa
Ukupholisa ulwelo (Isifudumezi esipholisayo se-PTC) isetyenziswa kakhulu ekutshitshiseni ubushushu beebhetri zemoto ngenxa yokusebenza kwayo kakuhle kokutshabalalisa ubushushu kunye nokukwazi ukugcina ubushushu obufanayo bebhetri.Xa kuthelekiswa nokupholisa umoya, ukupholisa ulwelo kunomsebenzi ongcono wokudlulisa ubushushu.Ukupholisa ulwelo kuphumeza ukutshabalalisa ubushushu ngokuqukuqela indawo yokupholisa kwimijelo ejikeleze ibhetri okanye ngokufunxa ibhetri kwindawo yokupholisa ukususa ubushushu.Ukupholisa ulwelo kuneenzuzo ezininzi malunga nokusebenza kakuhle kokupholisa kunye nokusetyenziswa kwamandla, kwaye kuye kwaba yeyona nto iphambili yolawulo lobushushu bebhetri.Okwangoku, iteknoloji yokupholisa ulwelo isetyenziselwa kwiimarike ezifana ne-Audi A3 kunye ne-Tesla Model S. Kukho izinto ezininzi ezichaphazela umphumo wokupholisa ulwelo, kubandakanywa nomphumo we-tube yokupholisa ulwelo, izinto eziphathekayo, ukupholisa okuphakathi, izinga lokuhamba kunye noxinzelelo. yehla kwindawo yokuphuma.Ukuthatha inani labagijimi kunye nobude-to-diameter ratio yabagijimi njengezinto eziguquguqukayo, impembelelo yale parameters yesakhiwo kumandla okupholisa kwenkqubo kwinqanaba lokukhutshwa kwe-2 C yafundwa ngokutshintsha ukulungelelaniswa kwee-inlets zomgijimi.Njengoko umlinganiselo wokuphakama unyuka, ubushushu obuphezulu bebhetri ye-lithium-ion buyancipha, kodwa inani labagijimi liyenyuka ukuya kwinqanaba elithile, kwaye ukuhla kweqondo lokushisa kwebhetri kuba kuncinci.
