Q: Pa -40°C, mphamvu yoyambira ya mota yotsekera chitseko imatha kuwirikiza kawiri. Kodi supercapacitor imatulutsabe mphamvu yokwanira ya instantaneous current pamene ESR ikukwera chifukwa cha kutentha kochepa?
A: Ikhoza kukwaniritsa zofunikira zonse. Tikukulimbikitsani kugwiritsa ntchito supercapacitor ya 25F 2.7V. Chida ichi chili ndi ESR < 30mΩ kutentha kwa chipinda komanso mphamvu yotulutsa nthawi yomweyo yoposa 15A. Ngakhale pa -40°C, pomwe mphamvu yotulutsa imachepa ndi 30%, imatha kutulutsa mphamvu yotulutsa yoposa 10A, kukwaniritsa zofunikira za injini yotsekera chitseko komanso kutsegula kutentha kochepa.

Q: Kodi mphamvu yochuluka bwanji imafunika kuti munthu atsegule kamodzi kokha? Ngati pakufunika kuchita zinthu ziwiri kapena zitatu motsatizana, kodi mphamvu ya supercapacitor ndi yokwanira?
A: Mwachitsanzo, galimoto yonyamula anthu, injini yotsekera chitseko ili ndi mphamvu yotsegula ya 3.5A ndipo nthawi yotsegula ya 0.1S. Mphamvu yofunikira potsegula zitseko ziwiri ndi iyi: 12V × 3.5A × 0.1S × nthawi ziwiri = 8.4J. Ndi zogwirira zitseko zinayi + zokhoma zitseko zinayi + zokhoma ziwiri za ana, mphamvu yonse yofunikira ndi: (8.4J × zokhoma 10) / 80% (kutembenuka bwino kukuyenera kukhala 80%) = 105J. Ndikofunikira kugwiritsa ntchito ma supercapacitor 5 25F 2.7V olumikizidwa motsatizana, omwe angapereke mphamvu zotsatirazi: 0.5 × 5F × (12V² - 9V²) = 157.5J. Ngakhale mphamvu yake itachepa pafupifupi 30%, imathabe kutsegula nthawi zambiri kuposa kawiri.

Q: Pa nthawi yozizira, kugwedezeka, kapena kukanikiza zinthu, mphamvu yamagetsi ya injini imatha kufika ma ampere makumi ambiri. Kodi ma supercapacitor amatha kupirira ma pulses otere?
A: Inde. Mwachitsanzo, potengera galimoto yonyamula anthu, mphamvu yamagetsi yozungulira yotsekeka ya loko ya chitseko nthawi zambiri imakhala 7-8A, mphamvu yamagetsi yozungulira yotsekeka ya loko ya ana ndi 2-3A, ndipo mphamvu yamagetsi yozungulira yozungulira yozungulira chitseko imakhala pafupifupi 10A. Supercapacitor ya 25F 2.7V imatha kutulutsa mphamvu yozungulira nthawi yomweyo yoposa 15A kutentha kwa chipinda. Ngakhale pa -40℃, pomwe mphamvu yotulutsira imachepa ndi 30%, imatha kutulutsa mphamvu yozungulira yoposa 10A, yomwe imakwaniritsa bwino momwe imagwiritsidwira ntchito pansi pa mikhalidwe ya makina ozungulira yotsekeka.

Q: Kodi mungatsimikizire bwanji kuti supercapacitor ikhoza kukwaniritsa moyo wonse wa chipangizocho kwa zaka zoposa 10? Kodi pali deta yoyenera komanso mitundu yowerengera nthawi ya moyo?
A: Ma supercapacitor a YMIN SDH ali m'gulu la ma supercapacitor omwe amalimbana ndi kutentha kwambiri pa 85℃. Zogulitsazi zimakwaniritsa zofunikira zamagalimoto. Kutengera ndi moyo wa zaka 10, pogwiritsa ntchito ma capacitor 5 mu makina opangira magetsi a 12V, omwe amagwira ntchito kwa maola atatu patsiku pa 45℃, nthawi yonse yogwirira ntchito ndi pafupifupi maola 11,000. Malinga ndi lamulo lowerengera moyo wa supercapacitor (kuchepa kwa kutentha kwa 10℃ kumawirikiza kawiri moyo wamagetsi, kuchepa kwa 0.1V kwa voliyumu kumawonjezera moyo wamagetsi ndi nthawi 1.5), chifukwa chake, pansi pa mikhalidwe ya 45℃ ndi 2.5V (voliyumu ya capacitor imodzi), moyo wamagetsi ndi maola 36,000, kupitirira kwambiri moyo wa kapangidwe ka chinthucho ndikukwaniritsa kwathunthu zosowa za moyo wazaka 10.

Q: Kachitidwe ka kuwonongeka kwa mphamvu ya supercapacitor ndi kukana kwamkati kumawonjezeka, komanso ubale pakati pa magetsi ndi kutentha.
A: Kuwonongeka kwa magwiridwe antchito a supercapacitors kumakhudzana kwambiri ndi zinthu ziwiri—ma electrode ndi electrolyte. Pa nthawi yayitali yogwira ntchito yotulutsa mphamvu, kuyika/kutulutsa ma ayoni m'ma pores a carbon omwe amayatsidwa nthawi zambiri kungayambitse kugwa pang'ono kapena kutsekeka kwa kapangidwe ka microporous, kuletsa kuyamwa kwa ma ion motero kuchepetsa mphamvu ndikuwonjezera kukana kwamkati. Mothandizidwa ndi magetsi ndi kutentha, ma electrolyte amawola ndi kusungunuka, motero amachepetsa mphamvu ndikuwonjezera kukana kwamkati. Voltage ndi chinthu chofunikira chomwe chimayambitsa kuwonongeka kwa magwiridwe antchito. Voltage yogwira ntchito ikakwera, electrolyte imawola mwachangu; kutsika kwa magetsi kumatha kuwonjezera moyo watsiku ndi tsiku. Pa kuchepa kulikonse kwa magetsi kwa 0.1V, moyo watsiku ndi tsiku umawonjezeka ndi nthawi 1.5. Kutentha kwambiri kumathandizira kwambiri kuwonongeka kwa ma electrolyte ndikuwonongeka kwa ma electrolyte. Malinga ndi Arrhenius's Law, pakuwonjezeka kulikonse kwa kutentha kwa 10°C, moyo watsiku ndi tsiku umachepetsedwa ndi theka. Kugwira ntchito pa kutentha kotsika kwambiri kumatha kuwonjezera moyo watsiku ndi tsiku wa chinthu.
