Q:1. Yiziphi izinzuzo eziyinhloko zama-supercapacitor ngaphezu kwamabhethri endabuko kuzinsimbi zeminyango yevidiyo?
A: Ama-Supercapacitor ahlinzeka ngezinzuzo njengokushaja okusheshayo ngemizuzwana (ukuvuka njalo nokuqoshwa kwevidiyo), impilo yomjikelezo omude kakhulu (imvamisa imijikelezo esukela amashumi kuya kumakhulu ezinkulungwane, inciphisa kakhulu izindleko zokuyilungisa), ukusekelwa kwamanje okuphezulu okuphezulu (ukuqinisekisa amandla asheshayo okusakaza ividiyo nokuxhumana okungenantambo), izinga lokushisa elibanzi lokusebenza (imvamisa -40°C kuya ku-+7 izinto zobungane), nobungani obungangeni ku-70). Babhekana ngokuphumelelayo nezingqinamba zamabhethri endabuko mayelana nokusetshenziswa njalo, ukuphuma kwamandla aphezulu, nobungane bemvelo.
Q:2. Ingabe izinga lokushisa elisebenzayo lama-supercapacitor lilungele izinhlelo zokusebenza zensimbi yokuncencethwa emnyango yevidiyo yangaphandle?
IMP: Yebo, ama-supercapacitor ngokuvamile anebanga lokushisa elibanzi lokusebenza (isb, -40°C kuya ku-+70°C), okuwenza afanelekele indawo ebanda kakhulu nokushisa okungase kuhlangane nezinsimbi zeminyango yevidiyo yangaphandle, okuqinisekisa ukusebenza okuzinzile esimweni sezulu esibi kakhulu.
Q:3. Ingabe i-polarity yama-supercapacitor ilungisiwe? Yiziphi izinyathelo okufanele zithathwe ngesikhathi sokufakwa? A: Ama-Supercapacitor ane-polarity ehleliwe. Ngaphambi kokufaka, qiniseka ukuthi uhlola izimpawu ze-polarity ku-casing. Ukuxhumeka okubuyela emuva akuvunyelwe ngokuphelele, njengoba lokhu kuzokwehlisa kakhulu ukusebenza kwe-capacitor noma kulimaze.
Q:4. Ama-supercapacitor ahlangabezana kanjani nezidingo zamandla aphezulu ngokushesha ezinsimbi zeminyango zamakholi wevidiyo nokutholwa kokunyakaza?
A: Izinsimbi zomnyango zevidiyo zidinga amaza aphakeme asheshayo lapho uqala ukurekhoda ividiyo, ukubhala ngekhodi nokudlulisa, nokuxhumana okungenantambo. Ama-Supercapacitor anokumelana okuphansi kwangaphakathi (ESR) futhi anganikeza amagagasi aphezulu aphezulu kakhulu, aqinisekise ugesi wesistimu ozinzile futhi avimbele ukuqalisa kabusha kwedivayisi noma ukungasebenzi kahle okubangelwa ukwehla kwamandla kagesi.
Q:5. Kungani ama-supercapacitor enempilo yomjikelezo omude kakhulu kunamabhethri? Kusho ukuthini lokhu ngezinsimbi zasemnyango zevidiyo?
A: Ama-Supercapacitor agcina amandla ngokusebenzisa i-electrostatic adsorption ebonakalayo, kunokusabela kwamakhemikhali, okuholela empilweni yomjikelezo omude kakhulu. Lokhu kusho ukuthi ingxenye yokugcina amandla ingase ingadingi ukushintshwa kuwo wonke umjikelezo wempilo wensimbi yokuncencethwa emnyango, okuyenza “ingabi nokunakekela” noma kwehliswe kakhulu izindleko zokuyilungisa. Lokhu kubaluleke kakhulu ezinsimbini zomnyango ezifakwe ezindaweni ezingalungile noma ezidinga ukwethembeka okuphezulu.
Q:6. Ingabe inzuzo ye-miniaturization yama-supercapacitor isiza kanjani ekwakhiweni kwemboni yezinsimbi zeminyango yevidiyo?
A: Ama-supercapacitor e-YMIN angenziwa amancane (isibonelo, ngobubanzi obungamamilimitha ambalwa kuphela). Lo sayizi ohlangene uvumela onjiniyela ukuthi bakhe izinsimbi zeminyango ezizacile, ezilula, futhi ezibukeka kahle kakhudlwana, ezihlangabezana nezidingo eziqinile zobuhle bezindlu zesimanje kuyilapho zishiya isikhala esengeziwe kwezinye izingxenye zokusebenza.
Q:7. Yiziphi izinyathelo okufanele zithathwe kusekethe yokushaja i-supercapacitor kusekethe yensimbi yokuncencethwa emnyango yevidiyo?
A: Isekhethi yokushaja kufanele ibe nokuvikelwa kwe-overvoltage (ukuvimbela i-voltage elinganiselwe ye-capacitor ukuthi idlule i-voltage yayo elinganiselwe) kanye nomkhawulo wamanje ukuze kuvinjwe ukushaja kwamanje okudlulele ekushiseni ngokweqile nokunciphisa impilo yayo. Uma ixhunywe ngokuhambisana nebhethri, kungase kudingeke isivimbeli esiwuchungechunge ukuze kukhawulwe yamanje.
F:8. Kungani ukulinganisa kwamandla kagesi kudingekile lapho kusetshenziswa ama-supercapacitor amaningi ochungechungeni? Kufinyelelwa kanjani lokhu?
IMPENDULO: Ngenxa yokuthi ama-capacitor angawodwana anamandla ahlukene kanye namaza avuzayo, ukuwaxhuma ngokuqondile ochungechungeni kuzoholela ekusabalaliseni kwamandla kagesi okungalingani, okungase kulimaza amanye ama-capacitor ngenxa yokugcwala ngokweqile. I-Passive balancing (kusetshenziswa i-parallel balancing resistors) noma ukulinganisa okusebenzayo (kusetshenziswa i-IC yokulinganisa ezinikele) kungasetshenziswa ukuze kuqinisekiswe ukuthi ama-voltage e-capacitor ngayinye angaphakathi kwebanga eliphephile.
F:9. Yimaphi amaphutha avamile angabangela ukusebenza kwama-supercapacitor kuma-doorbells ukuthi kwehle noma kuhluleke?
A: Amaphutha avamile ahlanganisa: ukubola kwamandla (ukuguga kwezinto ze-electrode, ukubola kwe-electrolyte), ukukhushulwa kokumelana kwangaphakathi (ESR) (ukuxhumana okungalungile phakathi kwe-electrode kanye nomqoqi wamanje, ukwehla kwe-electrolyte conductivity), ukuvuza (isakhiwo sokubeka uphawu esilimele, ukucindezela okukhulu kwangaphakathi), kanye nesifunda esifushane (i-diaphragm eyonakele, ukufuduka kwezinto ze-electrode).
F:10. Yiziphi izinyathelo zokuphepha okufanele zithathwe lapho ugcina ama-supercapacitor?
A: Kufanele agcinwe endaweni enezinga lokushisa eliphakathi kuka -30°C kuya +50°C kanye nomswakama ohlobene ongaphansi kuka-60%. Gwema amazinga okushisa aphezulu, umswakama ophezulu, nokushintsha kwezinga lokushisa okungazelelwe. Ziqhelelanise namagesi abolayo kanye nelanga eliqondile ukuze ugweme ukugqwala kwemithombe ne-casing. Ngemuva kokugcina isikhathi eside, kungcono ukwenza ukushaja nokukhipha kusebenze ngaphambi kokusetshenziswa.
F:11 Yiziphi izinyathelo zokuphepha okufanele zithathwe lapho kufakwa ama-supercapacitor ku-PCB kunsimbi yokuncencethwa emnyango?
A: Ungalokothi uvumele i-capacitor casing ukuthi ithinte ibhodi lesifunda ukuvimbela i-solder ukuthi ingangeni emigodini yezintambo ze-capacitor futhi ithinte ukusebenza. Izinga lokushisa le-soldering kanye nesikhathi kufanele kulawulwe (isb, izikhonkwane kufanele zicwiliswe ku-235 ° C okugeza nge-solder ≤5 imizuzwana) ukugwema ukushisa nokulimala ku-capacitor. Ngemuva kwe-soldering, ibhodi kufanele lihlanzwe ukuze kuvinjelwe izinsalela ekubangeleni izifunda ezimfushane.
F:12. Kufanele akhethwe kanjani ama-lithium-ion capacitor nama-supercapacitor ezinhlelweni zokusebenza zensimbi yokuncencethwa emnyango?
A: Ama-Supercapacitor anesikhathi eside sokuphila (imvamisa engaphezu kwemijikelezo engu-100,000), kuyilapho ama-lithium-ion capacitor anomthamo omkhulu wamandla kodwa ngokuvamile abe nempilo yomjikelezo omfushane (cishe amashumi ezinkulungwane zemijikelezo). Uma impilo yomjikelezo nokuthembeka kubaluleke kakhulu, ama-supercapacitor ayakhethwa.
F:13. Yiziphi izinzuzo ezithile zemvelo zokusebenzisa ama-supercapacitor kuma-doorbells?
A: Izinto ze-Supercapacitor azinabuthi futhi azihambisani nemvelo. Ngenxa yesikhathi eside sokuphila kwazo, zikhiqiza imfucuza encane kakhulu kuwo wonke umjikelezo wokuphila womkhiqizo kunamabhethri adinga ukushintshwa njalo, ehlisa kakhulu imfucuza kagesi kanye nokungcoliswa kwemvelo.
F:14. Ingabe ama-supercapacitor kuma-doorbells adinga isistimu yokuphatha ibhethri eyinkimbinkimbi (BMS)?
A: Ama-Supercapacitor kulula ukuwaphatha kunamabhethri. Kodwa-ke, ezintanjeni eziningi noma izimo zokusebenza ezinzima, ukuvikelwa kwe-overvoltage nokulinganisa kwamandla kagesi kusadingeka. Kuzinhlelo zokusebenza ezilula zeseli elilodwa, i-IC yokushaja enevoltage eningi kanye nokuvikela i-voltage ehlehlayo ingase yanele.
F: 15. Yiziphi izitayela zesikhathi esizayo kubuchwepheshe be-supercapacitor kumansimbi eminyango yevidiyo?
I: Ithrendi yesikhathi esizayo izoba ngokuya ekuminyana kwamandla okuphezulu (ukunweba isikhathi sokusebenza ngemva kokwenza kusebenze umcimbi), usayizi omncane (ukwenziwa kancane kwedivayisi okuphromothayo), i-ESR ephansi (ihlinzeka ngamandla asheshayo asheshayo), kanye nezixazululo zokuphatha ezihlangene ezihlakaniphe kakhulu (njengokuhlanganisa nobuchwepheshe bokuvuna amandla), ukudala izindawo zokuzwa ezihlakaniphile zasekhaya ezinokwethenjelwa nezingakhathali.
