Ku China, ma supercapacitor akhala akugwiritsidwa ntchito m'magalimoto amagetsi kwa zaka zambiri.Ndiye ubwino wa supercapacitor mumagalimoto amagetsi ndi chiyani?Chifukwa chiyani ma super capacitor ndi apamwamba kwambiri?
Super capacitors
super capacitor, galimoto yamagetsi, batire ya lithiamu
Eni magalimoto amagetsi akhala akuvutika ndi maulendo apanyanja, ndipo tchuthi lililonse padzakhala madandaulo.Choyamba, tiyeni tiwone komwe kumayambitsa nkhawa zapaulendo:
Wapakati mphamvu kachulukidwe mafuta a galimoto wamba ndi 13,000 Wh/kg.Pakalipano, kachulukidwe ka mphamvu zamabatire a lithiamu wamba ndi 200-300Wh/kg.Komabe, mphamvu zosinthira mphamvu zamagalimoto amagetsi amagetsi ndizokwera nthawi 2-3 kuposa ma locomotives a dizilo.Chifukwa chake, kuti mugwiritse ntchito mphamvu moyenera kwambiri, njira yabwino ndikuwonjezera kuchuluka kwa mphamvu zamabatire a lithiamu.
Ngakhale kachulukidwe ka mphamvu kachulukidwe mpaka ka 10 mu labotale, batire imabwezeredwa pambuyo pa milandu yambiri ndikutulutsa.
Ndiye kodi ndizotheka kuonjezera kuchuluka kwa mphamvu mpaka pamlingo wocheperako ndikusungabe kuchuluka koyenera komanso kutulutsa?
Supercapacitors
Capacitor ndi chimodzi mwazinthu zofunikira kwambiri zamagetsi zamagetsi.Mwachidule, zigawo ziwiri za zitsulo zojambula masangweji pepala insulating, ndi chipolopolo zoteteza anawonjezera kunja.Pakati pa zojambula ziwirizi pali malo omwe mphamvu zamagetsi zimasungidwa.Capacitor imagwiritsidwa ntchito ngati mphamvu yamagetsi pompopompo, kotero mphamvu yamagetsi yosungidwa siili yochulukirapo, ndipo kuchuluka kwa mphamvu kumakhala koyipa kwambiri kuposa batire.
Koma capacitor ili ndi ubwino umene batri ilibe: malipiro ndi kutulutsa moyo ndi wautali kwambiri - ngakhale mazana a zikwi za nthawi zolipiritsa ndi kutulutsa, kuwonongeka kwa ntchito kumakhala kochepa kwambiri.Choncho moyo wake ndi wofanana ndi mankhwalawo.
Chifukwa chomwe chimakhala ndi chiwongolero chabwino kwambiri komanso moyo wotulutsa ndi chifukwa chosungirako mphamvu ya capacitor chimakhazikitsidwa ndi mfundo zakuthupi ndipo sichimapanga zochitika zamakina.
Kotero tsopano ntchito ndikukulitsa mphamvu yamagetsi yosungirako mphamvu ya capacitor.Ndiye supercapacitor ikuwoneka.Cholinga chake ndikupangitsa capacitor kukhala mosungira, osati kungopereka mphamvu nthawi yomweyo.Koma vuto lalikulu ndimomwe mungasinthire kachulukidwe kamphamvu ka ma supercapacitor.
Supercapacitor imatha kugwiritsidwa ntchito ngati gwero lamagetsi pamagalimoto amagetsi pambuyo pakuwonjezera mphamvu zamagetsi.China yayamba kale kugwiritsa ntchito lusoli.Mu 2010 Shanghai World Expo, 36 super capacitor mabasi anawonetsedwa.Mabasiwa akhala akugwira ntchito mokhazikika kwa nthawi yayitali ndipo akugwirabe ntchito mpaka pano.
Mabasi a Supercapacitor ku Shanghai amatha kuyenda makilomita 40 m'mphindi 7
Koma luso lamakono silinafalikire ku njira zina ndi mizinda ina.Ilinso ndi vuto la "kuyenda panyanja" chifukwa cha kuchepa kwa mphamvu zamagetsi.Ngakhale kuti nthawi yolipirayo imafupikitsidwa kwambiri, zimangotenga mphindi zochepa kuti mupereke nthawi imodzi, koma imatha pafupifupi ma kilomita 40.Poyamba, mabasi ankafunika kuyimitsanso nthawi iliyonse ikayima.
Kuchulukana kwamphamvu kwa ma supercapacitor awa sikuli bwino ngati mabatire a lithiamu.Chifukwa chofunikira kwambiri ndichakuti ma dielectric okhazikika azinthu zopangidwa ndi kaboni mu supercapacitors akadali osakwanira.M'nkhani yotsatirayi, tikambirana za kupambana kwa China pakuwongolera mphamvu zama supercapacitor.
JYH HSU(JEC)) ndi wopanga ma supercapacitor aku China omwe amagwiritsa ntchito kafukufuku ndi chitukuko, kupanga ndi kugulitsa zida zosiyanasiyana zamagetsi.Ngati muli ndi mafunso okhudza zida zamagetsi kapena mukufuna kufunafuna mgwirizano wamabizinesi, mutha kulumikizana nafe nthawi iliyonse.
