Mubvunzo: 1. Ndezvipi zvakanakira zve supercapacitors kupfuura mabhatiri echinyakare ari mumabhero epamusuwo evhidhiyo?
A: Supercapacitors dzinopa zvakanakira zvakaita sekuchaja nekukurumidza mumasekonzi (kwekumuka nekurekodha mavhidhiyo nguva nenguva), hupenyu hwenguva refu kwazvo (hunowanzoita makumi kusvika kumazana ezviuru zvemasekonzi, zvichideredza zvakanyanya mari yekugadzirisa), rutsigiro rwemagetsi rwakakwira (kuona kuti simba rinobuda ipapo ipapo pakutepfenyura mavhidhiyo uye kutaurirana pasina waya), tembiricha yekushanda yakakura (kazhinji -40°C kusvika +70°C), uye kuchengetedzeka uye hushamwari kune nharaunda (hapana zvinhu zvine chepfu). Dzinogadzirisa zvinobudirira matambudziko emabhatiri echinyakare maererano nekushandiswa nguva dzose, simba rinobuda zvakanyanya, uye hushamwari kune nharaunda.
Q: 2. Ko tembiricha yekushanda yema supercapacitors yakakodzera here kushandiswa kwebhero repamusuwo revhidhiyo rekunze?
A: Ehe, ma supercapacitor anowanzo kuve nekupisa kwakakura kwekushanda (semuenzaniso, -40°C kusvika +70°C), zvichiita kuti akwanise zvakanaka munzvimbo dzinotonhora zvakanyanya uye dzinopisa dzinogona kusangana nemabhero ekunze evhidhiyo, zvichiita kuti kushanda kwakasimba kuve kwakasimba mumamiriro ekunze akaipisisa.
Mubvunzo:3. Ko polarity ye supercapacitors yakagadziriswa here? Ndedzipi nzira dzekudzivirira dzinofanira kutorwa panguva yekuisa? Mhinduro: Supercapacitors ine polarity yakagadziriswa. Usati waisa, iva nechokwadi chekutarisa polarity markings pa casing. Reverse connection inorambidzwa zvachose, sezvo izvi zvichikanganisa zvakanyanya mashandiro e capacitor kana kutoikuvadza.
Q: 4. Supercapacitors inosangana sei nezvinodiwa zvemagetsi zvepakarepo zvemabhero epamusuwo evhidhiyo ekuona mafambiro evhidhiyo?
A: Mabhero epamusuwo wevhidhiyo anoda ma "currents" akakwira ipapo ipapo pakutanga kurekodha vhidhiyo, kunyora nekutumira, uye kutaurirana pasina waya. Ma "supercapacitor" ane "low internal resistance" (ESR) uye anogona kupa ma "currents" akakwira zvakanyanya, zvichiita kuti "system voltage" ive yakasimba uye kudzivirira "startup" kana "disadvantage" inokonzerwa nekudonha kwe "voltage".
Mubvunzo: 5. Sei ma supercapacitor achirarama kwenguva yakareba kupfuura mabhatiri? Izvi zvinorevei kumabhero epamusuwo evhidhiyo?
A: Supercapacitors inochengetedza simba kuburikidza nekunyoroveswa kwemagetsi, kwete makemikari, zvichikonzera hupenyu hwakareba kwazvo. Izvi zvinoreva kuti chinhu chinochengetedza simba chingasade kutsiviwa muhupenyu hwese hwebhero repasuo revhidhiyo, zvichiita kuti "risagadziriswe" kana kuderedza zvakanyanya mari yekugadzirisa. Izvi zvakakosha zvikuru kumabhero epasuo akaiswa munzvimbo dzisina kunaka kana kuti anoda kuvimbika kwakanyanya.
Q:6. Kubatsira kwe supercapacitors kugadzira ma "miniaturization" kunobatsira sei mukugadzirwa kwema "video doorbells" muindasitiri?
A: Masupercapacitor eYMIN anogona kugadzirwa madiki (semuenzaniso, ane dhayamita yemamilimita mashoma chete). Hukuru uhwu hudiki hunobvumira mainjiniya kugadzira mabhero emusuwo akatetepa, akareruka, uye anoyevedza, achizadzisa zvinodiwa zvakanyanya zverunako rwedzimba dzemazuva ano uku achisiya nzvimbo yakawanda yezvimwe zvinhu zvinoshanda.
Q: 7. Ndezvipi zvinofanirwa kutorwa mu supercapacitor charging circuit mu video doorbell circuit?
A: Dunhu rekuchaja rinofanira kunge riine dziviriro ye overvoltage (kudzivirira voltage ye capacitor kuti isapfuure voltage yayo yakayerwa) uye current inoganhurira kudzivirira overcharge current kuti isapfuure uye kuderedza hupenyu hwayo. Kana yakabatana pamwe chete nebhatiri, series resistor inogona kudiwa kuti iganure current.
F:8. Sei kuenzana kwemagetsi kuchidikanwa kana ma supercapacitors akawanda achishandiswa mu series? Izvi zvinoitwa sei?
A: Nekuti ma capacitor ega ega ane kugona kwakasiyana uye ma leakage currents, kuabatanidza zvakananga mu series kuchaita kuti voltage distribution isaenzane, zvichigona kukuvadza mamwe ma capacitor nekuda kwe overvoltage. Passive balancing (uchishandisa parallel balancing resistors) kana active balancing (uchishandisa dedicated balancing IC) zvinogona kushandiswa kuona kuti voltages dze capacitor yega yega dziri mukati me range yakachengeteka.
F:9. Ndezvipi zvikanganiso zvinowanzoita kuti mashandiro ema supercapacitors mumabhero emusuwo aderere kana kuti asashande zvakanaka?
A: Zvikanganiso zvinowanzo sanganisira: kuora kwesimba (kukwegura kwechinhu chemagetsi, kuora kwemagetsi), kuwedzera kwekudzivirira kwemukati (ESR) (kusabatana zvakanaka pakati peelectrode nemuunganidzi wemagetsi, kudzikira kwesimba remagetsi), kubuda kwemvura (chimiro chekuvharwa kwesimbi chakakuvara, kumanikidzwa kwemukati kwakanyanya), uye kupfupika kwemhepo (diaphragm yakakuvara, kufamba kwechinhu chemagetsi).
F:10. Ndezvipi matanho anofanira kutorwa pakuchengeta ma supercapacitors?
A: Dzinofanira kuchengetwa munzvimbo ine tembiricha iri pakati pe -30°C kusvika +50°C uye hunyoro huri pasi pe60%. Dzivisa tembiricha yakakwira, hunyoro hwakawanda, uye shanduko dzetembiricha dzinongoerekana dzaitika. Dzivirira kure nemagasi anoparadza uye zuva rakananga kudzivirira ngura yemaradhi nekavha. Mushure mekuchengetedza kwenguva refu, zvakanaka kuita chaji uye kuburitsa mvura usati washandisa.
F:11 Ndezvipi matanho anofanira kutorwa kana muchibatanidza ma supercapacitors kuPCB iri pamusuwo?
A: Usambobvumira capacitor casing kuti ibatane necircuit board kudzivirira solder kuti isapinde mumaburi ewiring e capacitor uye kukanganisa mashandiro ayo. Tembiricha yekusoldering nenguva zvinofanirwa kudzorwa (semuenzaniso, mapini anofanira kunyudzwa mubhavhu rekusolder re 235°C kwemasekondi ≤5) kudzivirira kupisa zvakanyanya uye kukuvara kwe capacitor. Mushure mekusoldering, bhodhi rinofanira kucheneswa kudzivirira masara kubva pakukonzera short circuits.
F:12. Ma capacitor e lithium-ion nema supercapacitors anofanira kusarudzwa sei pakushandisa mabhero epamusuwo wevhidhiyo?
A: MaSupercapacitor ane hupenyu hwakareba (kazhinji anopfuura 100,000 cycles), nepo lithium-ion capacitors ane simba rakawanda asi anowanzova nehupenyu hupfupi hwe cycles (anenge makumi ezviuru zve cycles). Kana hupenyu hwe cycle uye kuvimbika kwakakosha zvikuru, maSupercapacitor ndiwo anofarirwa.
F:13. Ndezvipi zvakanakira zvakatipoteredza zvekushandisa ma supercapacitors mumabhero emusuwo?
A: Zvinhu zveSupercapacitor hazvina chepfu uye hazvina njodzi kune zvakatipoteredza. Nekuda kwehupenyu hwazvo hwakareba, zvinoburitsa marara mashoma muhupenyu hwechigadzirwa kupfuura mabhatiri anoda kutsiviwa nguva nenguva, zvichideredza zvakanyanya marara emagetsi uye kusvibiswa kwezvakatipoteredza.
F:14. Ko ma supercapacitor ari mumabhero emusuwo anoda sisitimu yakaoma yekutarisira mabhatiri (BMS) here?
A: MaSupercapacitor ari nyore kushandisa pane mabhatiri. Zvisinei, kune tambo dzakawanda kana mamiriro ekushanda akaomarara, dziviriro ye overvoltage uye kuenzanisa voltage zvichiri kudiwa. Kune zviri nyore kushandisa sero rimwe chete, IC yekuchaja ine overvoltage uye reverse voltage dziviriro inogona kukwana.
F: 15. Ndeapi mafambiro ari mberi mune tekinoroji ye supercapacitor yemabhero epamusuwo evhidhiyo?
A: Mufambiro weramangwana uchava wekuwedzera simba (kuwedzera nguva yekushanda mushure mekuvhurwa kwechiitiko), saizi diki (kuwedzera kukurudzira miniaturization yemudziyo), kudzikira kweESR (kupa simba rakasimba ipapo ipapo), uye mhinduro dzakangwara dzekutarisira (dzakadai sekubatanidzwa netekinoroji yekuunganidza simba), kugadzira ma node ekuona dzimba akavimbika uye asina kugadziriswa.
