Q:1. Kodi ubwino waukulu wa ma supercapacitor ndi wotani poyerekeza ndi mabatire achikhalidwe omwe ali m'mabelu a zitseko zamakanema?
A: Ma Supercapacitor amapereka zabwino monga kuyatsa mwachangu mumasekondi (pofuna kudzuka nthawi zonse ndi kujambula makanema), moyo wautali kwambiri (nthawi zambiri umakhala wa ma cycles makumi ambiri mpaka mazana ambiri, zomwe zimachepetsa kwambiri ndalama zokonzera), kuthandizira kwamphamvu kwambiri (kutsimikizira mphamvu yachangu yowonera makanema ndi kulumikizana opanda zingwe), kutentha kwakukulu kogwira ntchito (nthawi zambiri -40°C mpaka +70°C), komanso chitetezo ndi kusamala chilengedwe (popanda zinthu zoopsa). Amathetsa mavuto a mabatire achikhalidwe pankhani yogwiritsidwa ntchito pafupipafupi, mphamvu zambiri, komanso kusamala chilengedwe.
Q: 2. Kodi kutentha kwa ma supercapacitor ogwiritsira ntchito ndi koyenera kugwiritsa ntchito belu la panja la kanema?
A: Inde, ma supercapacitor nthawi zambiri amakhala ndi kutentha kwakukulu kogwirira ntchito (monga -40°C mpaka +70°C), zomwe zimapangitsa kuti azigwirizana bwino ndi malo ozizira kwambiri komanso otentha omwe mabelu akunja a pakhoma angakumane nawo, zomwe zimapangitsa kuti ntchito ikhale yokhazikika munyengo yoipa kwambiri.
Q:3. Kodi polarity ya ma supercapacitor ndi yokhazikika? Ndi njira ziti zodzitetezera zomwe ziyenera kutengedwa mukakhazikitsa? A: Ma Supercapacitor ali ndi polarity yokhazikika. Musanayike, onetsetsani kuti mwayang'ana zizindikiro za polarity zomwe zili pa casing. Kulumikizana kumbuyo ndikoletsedwa kwambiri, chifukwa izi zidzawononga kwambiri magwiridwe antchito a capacitor kapena kuiwononga.
Q:4. Kodi ma supercapacitor amakwaniritsa bwanji zofunikira zamphamvu za mabelu apakhomo a kanema nthawi yomweyo kuti aziyimba makanema ndi kuzindikira mayendedwe?
A: Mabelu a pakhoma la kanema amafunika mphamvu yamagetsi yothamanga nthawi yomweyo poyambitsa kujambula kanema, kulemba ndi kutumiza, komanso kulankhulana opanda zingwe. Ma Supercapacitor ali ndi mphamvu yamkati yotsika (ESR) ndipo amatha kupereka mphamvu yamagetsi yokwera kwambiri, kuonetsetsa kuti mphamvu yamagetsi ya dongosolo ndi yokhazikika komanso kupewa kuyambitsanso kwa chipangizo kapena zolakwika zomwe zimachitika chifukwa cha kuchepa kwa mphamvu yamagetsi.
Q:5. N’chifukwa chiyani ma supercapacitor amakhala ndi moyo wautali kuposa mabatire? Kodi izi zikutanthauza chiyani pa mabelu a pakhoma a kanema?
Yankho: Ma Supercapacitor amasunga mphamvu kudzera mu ma adsorption amagetsi, m'malo mwa zochita za mankhwala, zomwe zimapangitsa kuti ikhale nthawi yayitali kwambiri. Izi zikutanthauza kuti chinthu chosungira mphamvu sichingafunike kusinthidwa nthawi yonse ya moyo wa belu la chitseko cha kanema, zomwe zimapangitsa kuti "chisakonzedwe" kapena kuchepetsa kwambiri ndalama zokonzera. Izi ndizofunikira kwambiri pamabelu a chitseko omwe amaikidwa m'malo ovuta kapena omwe amafunikira kudalirika kwambiri.
Q:6. Kodi ubwino wa miniaturization wa supercapacitors umathandiza bwanji pakupanga mabelu a zitseko zamakanema m'mafakitale?
A: Ma supercapacitor a YMIN amatha kuchepetsedwa (mwachitsanzo, okhala ndi mainchesi ochepa okha). Kukula kochepa kumeneku kumalola mainjiniya kupanga mabelu a zitseko omwe ndi opyapyala, opepuka, komanso okongola kwambiri, kukwaniritsa zofunikira zokongoletsa nyumba zamakono pomwe akusiya malo ochulukirapo pazinthu zina zogwirira ntchito.
Q:7. Ndi njira ziti zodzitetezera zomwe ziyenera kutengedwa mu circuit yochajira supercapacitor mu circuit ya belu la chitseko cha kanema?
Yankho: Dongosolo lochajira liyenera kukhala ndi chitetezo cha overvoltage (kuti magetsi ovoteledwa a capacitor asapitirire voltage yake yovoteledwa) komanso kuchepetsa mphamvu yamagetsi kuti magetsi ovoteledwa asamatenthe kwambiri komanso kuchepetsa nthawi yake yogwira ntchito. Ngati lilumikizidwa limodzi ndi batri, choletsa cha series chingafunike kuti chichepetse mphamvu yamagetsi.
F:8. N’chifukwa chiyani kuli kofunikira kulinganiza magetsi pamene ma supercapacitor angapo akugwiritsidwa ntchito motsatizana? Kodi izi zimachitika bwanji?
A: Popeza ma capacitor osiyanasiyana ali ndi mphamvu zosiyanasiyana komanso mafunde otuluka, kuwalumikiza mwachindunji motsatizana kumabweretsa kugawa kwa magetsi kosagwirizana, zomwe zitha kuwononga ma capacitor ena chifukwa cha overvoltage. Kulinganiza kosasinthasintha (pogwiritsa ntchito parallel balancing resistors) kapena active balancing (pogwiritsa ntchito dedicated balancing IC) kungagwiritsidwe ntchito kuonetsetsa kuti ma voltage a capacitor iliyonse ali mkati mwa malo otetezeka.
F:9. Ndi zolakwika ziti zomwe zimachitika kawirikawiri zomwe zingayambitse kuchepa kapena kulephera kwa magwiridwe antchito a ma supercapacitor m'mabelu a pakhomo?
A: Zolakwika zomwe zimafala kwambiri ndi izi: kuwonongeka kwa mphamvu (kukalamba kwa zinthu zama electrode, kuwonongeka kwa ma electrolyte), kukana kwamkati (ESR) (kusagwirizana bwino pakati pa electrode ndi chosonkhanitsa magetsi, kuchepa kwa electrolyte conductivity), kutayikira (kapangidwe kotseka kowonongeka, kupanikizika kwamkati kwambiri), ndi short circuit (diaphragm yowonongeka, kusamuka kwa zinthu zama electrode).
F:10. Ndi njira ziti zotetezera zomwe ziyenera kutengedwa posunga ma supercapacitors?
A: Ziyenera kusungidwa pamalo otentha kuyambira -30°C mpaka +50°C komanso chinyezi chochepera 60%. Pewani kutentha kwambiri, chinyezi chochuluka, komanso kusintha kwadzidzidzi kwa kutentha. Sungani kutali ndi mpweya wowononga komanso kuwala kwa dzuwa mwachindunji kuti mupewe kuwonongeka kwa zingwe ndi chivundikirocho. Mukasunga kwa nthawi yayitali, ndibwino kuyambitsa kuyatsa ndi kutulutsa madzi musanagwiritse ntchito.
F:11 Ndi njira ziti zodzitetezera zomwe ziyenera kutengedwa poyika ma supercapacitors ku PCB yomwe ili pakhomo?
A: Musalole kuti capacitor casing ilumikizane ndi circuit board kuti solder isalowe m'mabowo a waya a capacitor ndikusokoneza magwiridwe antchito. Kutentha ndi nthawi yosoldering ziyenera kulamulidwa (monga, ma pini ayenera kumizidwa mu bafa la solder la 235°C kwa masekondi ≤5) kuti apewe kutentha kwambiri komanso kuwonongeka kwa capacitor. Pambuyo posoldering, board iyenera kutsukidwa kuti ipewe zotsalira kuti zisayambitse ma short circuits.
F:12. Kodi ma capacitor a lithiamu-ion ndi ma supercapacitor ayenera kusankhidwa bwanji kuti agwiritsidwe ntchito pa belu la pakhomo la kanema?
A: Ma Supercapacitor amakhala ndi moyo wautali (nthawi zambiri amakhala ndi ma cycle opitilira 100,000), pomwe ma capacitor a lithiamu-ion amakhala ndi mphamvu zambiri koma nthawi zambiri amakhala ndi moyo wafupikitsa wa ma cycle (pafupifupi ma cycle zikwi makumi ambiri). Ngati moyo wa ma cycle ndi kudalirika ndizofunikira kwambiri, ma supercapacitor ndi omwe amakondedwa.
F:13. Kodi ubwino wogwiritsa ntchito ma supercapacitor m'mabelu a pakhomo ndi wotani?
Yankho: Zipangizo za Supercapacitor sizowononga komanso siziwononga chilengedwe. Chifukwa cha nthawi yayitali ya moyo wawo, zimapanga zinyalala zochepa kwambiri panthawi yonse ya moyo wa chinthucho kuposa mabatire omwe amafunika kusinthidwa pafupipafupi, zomwe zimachepetsa kwambiri zinyalala zamagetsi ndi kuipitsa chilengedwe.
F:14. Kodi ma supercapacitor omwe ali m'zitseko amafunikira njira yovuta yoyendetsera mabatire (BMS)?
Yankho: Ma Supercapacitor ndi osavuta kugwiritsa ntchito kuposa mabatire. Komabe, pazingwe zingapo kapena mikhalidwe yovuta yogwirira ntchito, chitetezo cha overvoltage ndi kulinganiza voltage ndizofunikirabe. Pa ntchito zosavuta za selo imodzi, IC yochaja yokhala ndi overvoltage ndi reverse voltage protection ingakhale yokwanira.
F: 15. Kodi ndi zinthu ziti zomwe zidzachitike mtsogolo muukadaulo wa supercapacitor pa mabelu a zitseko zamakanema?
A: Zomwe zidzachitike mtsogolomu zidzakhala za kuchuluka kwa mphamvu (kuwonjezera nthawi yogwirira ntchito pambuyo poti chochitika chayamba kugwira ntchito), kukula kochepa (kupititsa patsogolo kuchepetsedwa kwa chipangizo), kuchepa kwa ESR (kupereka mphamvu yamphamvu nthawi yomweyo), ndi njira zanzeru zoyendetsera zinthu (monga kuphatikiza ndi ukadaulo wokolola mphamvu), kupanga ma node odalirika komanso osakonza nyumba.
