menene amfanin tsarin sarrafa hankali na zafin baturi
A cikin dogon lokaci, sabbin motocin makamashi, musamman motocin lantarki masu tsabta, za su ci gaba da ci gaba da ci gaban ci gaban da suke samu a duniya, tare da tsauraran buƙatun fitar da hayaki, da ƙarin ingantattun fasahar batir da farashi, ci gaba da inganta ababen more rayuwa, da karɓuwar masu amfani da motocin lantarki. tsayi da tsayi.
Abu mafi mahimmanci a cikin motar lantarki shine baturi. Don batura, lokaci ba wuka ba ne, amma zafin jiki wuka ne. Komai kyawun fasahar baturi, matsanancin zafi yana da matsala. Don haka, tsarin sarrafa zafin baturi ya kasance.
Dangane da ƙamus kamar na ternary lithium da tsarin lantarki na ternary, mun riga mun tattauna ajin karatu a baya, kuma a yau za mu ja tsarin sarrafa zafin baturi na motocin lantarki. Don haka, mun tuntubi Mr. Lars Kostede, shugaban ayyukan hukumar aiwatar da ayyukan na HELLA kasar Sin, wanda kwararre ne a wannan fanni.
Menene tsarin sarrafa thermal?
Kada wannan kalmar ta ruɗe ta, kamar marufi ne na wayar hannu a gefen hanya, ko kuma, a sanya shi a hankali, “polymer finish.” “Tsarin gudanarwa na thermal” ya fi kama da duk abin da ke tattare da shi.
Daban-daban tsarin kula da thermal sun yi niyya ga wurare daban-daban, kamar tankin ruwa na injin, kuma na’urar sanyaya iska a kan motar ita ce babban abin da ke tabbatar da jin daɗin tafiya – amma ba haka ba. Duk lokacin da aka dakatar da kwandishan motar, komai ƙarfin ƙarfin tacewa na chassis, yaya ingancin NVH yake? Rolls-Royce ba tare da kwandishan ba ba shi da kyau kamar Chery-musamman a wannan lokacin na shekara, na’urorin kwantar da hankali suna da mahimmanci ga rayuwar masu mota. Muhimmanci.
Tsarin sarrafa zafin batirin abin hawa na lantarki yana magance wannan batu.
Me yasa batura ke buƙatar tsarin sarrafa zafi?
Idan aka kwatanta da motocin mai, haɗarin amincin “na musamman” na motocin lantarki ya ta’allaka ne a cikin kula da yanayin zafi na baturin wuta. Bayan guduwar thermal ya auku, sarkar yaduwa mai kama da yanayin zafi yana faruwa.
Dauki shahararren baturin lithium 18650 a matsayin misali. Yawancin ƙwayoyin baturi suna yin fakitin baturi. Idan zafin na’urar baturi daya ba ta da iko, za’a canza zafin zuwa kewaye, sannan kuma kwayoyin batirin da ke kewaye zasu sami amsawar sarkar daya bayan daya kamar wuta. A yayin wannan tsari, za a ƙaddamar da batutuwan bincike da yawa, waɗanda suka haɗa da matsakaicin ƙimar haɓakar zafin jiki, haɓakar sinadarai da zafin wutar lantarki, canjin zafi da haɗaɗɗiya.
Hanya mafi sauƙi kuma mafi inganci don sarrafa irin wannan sarkar zafi mai gudu ita ce ƙara wani Layer na rufi tsakanin raka’o’in batirin wutar lantarki-yanzu motocin mai da yawa suna kula da shi, kuma an sanya da’irar rufin rufi a wajen baturin.
Duk da cewa rufin rufin shine mafi sauƙi nau’in tsarin sarrafa zafin baturi, kuma shine mafi wahala. A gefe ɗaya, kauri na rufin rufin zai shafi gabaɗayan fakitin baturi kai tsaye; a daya bangaren kuma, rufin insulation shine “tsarin kula da thermal” wanda ke rage jinkirin fakitin baturi lokacin da yake bukatar dumama ko sanyaya.
Mafi kyawun zafin aiki na batirin lithium na gargajiya shine 0 ℃ ~ 40 ℃. Yawan zafin jiki zai rage ƙarfin ajiyar baturin da rayuwar sake zagayowar baturin. A haƙiƙa, yanayin zafi na ƙasa a lokacin rani yana da yuwuwar wuce 40 ° C, kuma kowa ya san cewa zafin motar da ke rufe yana iya wuce 60 ° C a lokacin rani. Hakazalika, cikin fakitin baturi shima wuri ne da aka killace kuma zai yi zafi sosai… Ga motocin lantarki, cikakken tsarin sarrafa zafin baturi yana da matukar muhimmanci.
Wasu nau’ikan motocin lantarki da aka sayar da su a kan sikeli mai girma a Arewacin Amurka a cikin 2011, saboda tsarin sarrafa zafin baturi mai sauƙi, ƙarfin baturin ya lalace sosai bayan shekaru 5, wanda ya sa masu motocin Arewacin Amurka suka biya $ 5,000 don maye gurbin baturin. .
Kuma idan zafin jiki ya yi ƙasa da 0 ° C, ƙarfin fitarwa na batir lithium na yau da kullun zai ragu – wanda kuma aka sani da “gudu”. Bugu da ƙari, ƙananan zafin jiki, mafi muni aikin ionization na baturi, wanda zai haifar da raguwa a cikin aikin caji, wato, “wuya don caji da ƙananan iyawa”. Kyakkyawan tsarin kula da yanayin zafi na baturi zai dumama fakitin baturi kafin yin caji a ƙananan zafin jiki, har ma yana da aikin rufewa mai ƙarancin kuzari lokacin da aka haɗa wutar lantarki.
A haƙiƙa, wasu kamfanoni sun ƙera batir lithium masu ƙarancin zafin jiki wanda ya dace da matsanancin yanayin yanayin muhalli. Misali, batirin lithium mai ƙarancin zafin jiki wanda aka ƙera don mahallin igiya zai iya samun saurin caji a 0.2C a -40C da ƙarfin fitarwa wanda bai gaza 80% ba. Wasu suna aiki da kyau a cikin kewayon zafin jiki na -50 ° C zuwa 70 ° C kuma ba sa buƙatar kowane taimako daga tsarin kula da thermal.
Wadannan batura lithium suna da wahala wajen biyan bukatun kamfanonin kera motoci ta fuskar yawan makamashi da tsada, don haka ga kamfanonin kera motoci, tsarin sarrafa zafin baturi har yanzu mafita ce ta tattalin arziki don tabbatar da rayuwar batir da yanayin aiki.
Ta yaya tsarin sarrafa zafin baturi ke aiki?
Ka’idar aiki na tsarin sarrafa zafin baturi yayi kama da na na’urar sanyaya iska.
