Ndi chitukuko champhamvu chamsika watsopano wamagalimoto amagetsi, ma charger amagalimoto, monga chimodzi mwazinthu zazikulu, akupita patsogolo kwambiri, miniaturization komanso kudalirika kwakukulu.
Shanghai Electronics Co., Ltd., yokhala ndi luso laukadaulo la capacitor, sikuti imangothandiza Xiaomi Fast Charge kukwaniritsa zotsogola pazamagetsi ogula, komanso imapereka chithandizo chofunikira pakukweza kwaukadaulo wama charger agalimoto.
1. Kukula kwakung'ono komanso kachulukidwe kakang'ono kamphamvu: kusintha kwa malo kwa ma charger agalimoto
Mmodzi mwa mpikisano waukulu wa ma capacitor ali mu lingaliro lake "laling'ono, mphamvu zazikulu". Mwachitsanzo, mtundu wamadzi wotsogoleraLKM mndandanda capacitors(450V 8.2μF, kukula kokha 8 * 16mm) opangidwa kwa Xiaomi nawuza mfuti kukwaniritsa ntchito ziwiri za buffering mphamvu ndi kukhazikika voteji ndi kukhathamiritsa zipangizo mkati ndi nyumba.
Ukadaulo uwu umagwiranso ntchito pazida zamagalimoto - mu malo ochepera pa bolodi, ma capacitor ang'onoang'ono amatha kuwonjezera kuchuluka kwa mphamvu ya module yotsatsira pomwe amachepetsa kuthamanga kwa kutentha. Kuphatikiza apo, 's KCX series (400V 100μF) ndi NPX series solid-state capacitors (25V 1000μF) yopangidwira makamaka GaN yolipiritsa mwachangu apereka mayankho okhwima pakutembenuza koyenera kwa DC/DC kwa ma charger omwe ali ndi ma frequency apamwamba komanso otsika kwambiri.
2. Kukaniza madera owopsa: Chitsimikizo chodalirika pazochitika zapabwalo
Ma charger omwe ali pa board amafunika kupirira zovuta zogwirira ntchito monga kugwedezeka, kutentha kwambiri, ndi chinyezi chambiri. ma capacitor adapangidwa kuti azilimbana ndi kugunda kwamphezi komanso mafunde akulu othamanga kwambiri. Mwachitsanzo, mndandanda wa LKM ukhoza kugwira ntchito mokhazikika m'malo a -55 ℃ ~ 105 ℃ ndi moyo wa maola 3000.
Tekinoloje yake yolimba yamadzimadzi ya hybrid capacitor (monga anti-vibration capacitor yomwe imagwiritsidwa ntchito pama charger aku board) yadutsa ziphaso za IATF16949 ndi AEC-Q200 ndipo zagwiritsidwa ntchito bwino poyang'anira madambwe ndi ma module opangira magetsi atsopano monga BYD. Kudalirika kwakukulu kumeneku ndiye kofunika kwambiri kuti ma charger omwe ali pa board athe kuthana ndi malo ovuta.
3. Kuchita bwino kwambiri komanso kukhathamiritsa kwamphamvu kwamphamvu: kufananiza ukadaulo wa m'badwo wachitatu wa semiconductor
Mawonekedwe apamwamba kwambiri a zida zamtundu wachitatu za semiconductor monga gallium nitride (GaN) ndi silicon carbide (SiC) zimayika zofunikira kwambiri pakuyankha kwanthawi yayitali komanso kutayika kochepa kwa ma capacitor.
Mndandanda wa KCX ukhoza kusinthira ku high-frequency LLC resonant topology ndikuwongolera mphamvu zonse zama charger omwe ali pa bolodi pochepetsa ESR (kukana kofananira) ndikuwonjezera kukana kwapano.
Mwachitsanzo, kuwongolera bwino kwamphamvu kwamtundu wa LKM mu Xiaomi kulipiritsa mfuti kumachepetsa kutayika kwa mphamvu pakulipiritsa. Izi zitha kusamutsidwira kumayendedwe othamanga kwambiri amphamvu kwambiri.
4. Mgwirizano wamakampani ndi ziyembekezo zamtsogolo
Chitsanzo cha mgwirizano ndi Xiaomi (monga chitukuko cha capacitor) chimapereka chitsanzo cha malo opangira ma charger. Gulu lake laukadaulo lakwanitsa kufananitsa bwino ma capacitor ndi zida zamagetsi potenga nawo gawo mozama pakufufuza ndi chitukuko cha opanga magetsi (monga mgwirizano ndi opanga ma chip monga PI ndi Innoscience).
M'tsogolomu, ndi kutchuka kwa nsanja za 800V high-voltage ndi teknoloji yowonjezereka, ikupanga makina apamwamba kwambiri a capacitor capacitor, omwe akuyembekezeka kupititsa patsogolo chitukuko cha ma charger omwe ali pa bolodi kuti akhale opepuka komanso osakanikirana.
Mapeto
Kuchokera pamagetsi ogula zinthu kupita kumalo opangira magalimoto, ma capacitor awonetsa gawo lalikulu la ma capacitor ngati "mahabu owongolera mphamvu" kudzera muukadaulo waukadaulo komanso kusintha kwa zochitika. Kugwirizana kwake kopambana ndi Xiaomi Fast Charge sikumangopereka mayankho ogwira mtima pamsika wa ogula, komanso kumadzetsa chitsogozo chatsopano pakukweza kwaukadaulo kwa ma charger aku board. Motsogozedwa ndi magalimoto amphamvu ndi ukadaulo wothamangitsa mwachangu, 'kukula kwakung'ono ndiukadaulo wodalirika kwambiri wa capacitor upitiliza kutsogolera kusintha kwamakampani.
