Nekukura kwakasimba kwemusika wemotokari itsva dzinoshandisa simba, machaja emotokari, sechimwe chezvinhu zvikuru, ari kushanduka achienda pakushanda zvakanaka, kuita kuti mota dzive shoma uye dzakavimbika zvakanyanya.
Shanghai Electronics Co., Ltd., nehunyanzvi hwayo hwekugadzira capacitor, haingobatsiri Xiaomi Fast Charge chete kuti ibudirire mune zvemagetsi zvevatengi, asiwo inopa rutsigiro rwakakosha pakuvandudza tekinoroji yemachaja emota.
1. Saizi diki uye simba rakawanda: kuchinja kwenzvimbo kwemachaja emota
Imwe yemakwikwi makuru ema capacitor iri mupfungwa yayo yekugadzira "hukuru hudiki, hukuru". Semuenzaniso, mhando ye lead yemvuraMa capacitor eLKM akatevedzana(450V 8.2μF, saizi 8 * 16mm chete) yakagadzirirwa pfuti dzekuchaja dzeXiaomi dzinoita mabasa maviri ekugadzirisa simba uye kugadzikana kwemagetsi nekuvandudza zvinhu zvemukati nemaumbirwo.
Tekinoroji iyi inoshandawo kumachaja emota - munzvimbo shoma iri mubhodhi, macapacitor madiki anogona kuwedzera simba remota yekuchaja uku achideredza kumanikidzwa kwekupiswa kwekupisa. Pamusoro pezvo, maKCX series (400V 100μF) uye maNPX series solid-state capacitors (25V 1000μF) akagadzirirwa zvakananga GaN fast charging akapa mhinduro dzakakura dzekushandura DC/DC zvinobudirira machaja ari mubhodhi ane hunhu hwawo hwepamusoro-frequency uye hwakaderera hweimpedance.
2. Kuramba nharaunda dzakaipisisa: Vimbiso yekuvimbika kune zviitiko zviri muchikepe
Machaja ari mubhazi anofanirwa kutsungirira mamiriro ekushanda akaomarara akadai sekudedera, kupisa kwakanyanya, uye hunyoro hwakawanda. Ma capacitor akagadzirwa kuti adzivise kurohwa nemheni uye mafungu makuru emvura. Semuenzaniso, LKM series inogona kushanda zvakadzikama munzvimbo ye -55℃ ~ 105℃ ine hupenyu hwemaawa anosvika 3000.
Tekinoroji yayo ye solid-liquid hybrid capacitor (yakadai se anti-vibration capacitor inoshandiswa mumacharger ari mubhodhi) yapasa zvitupa zveIATF16949 neAEC-Q200 uye yakashandiswa zvinobudirira muma domain controllers nema charger modules emotokari itsva dzesimba dzakadai seBYD. Kuvimbika uku kwakanyanya ndicho chinhu chikuru chinodiwa kuti macharger ari mubhodhi akwanise kurarama nemamiriro ezvinhu akaoma.
3. Kushanda nesimba zvakanyanya uye kugadzirisa mashandiro esimba: kufananidza tekinoroji yesemiconductor yechizvarwa chechitatu
Hunhu hwepamusoro-soro hwezvishandiso zve semiconductor zvechizvarwa chechitatu zvakaita se gallium nitride (GaN) uye silicon carbide (SiC) zvinoisa zvinodiwa zvakanyanya pakupindura kwepamusoro-soro uye kurasikirwa kushoma kwema capacitor.
Ma's KCX series anogona kuchinjika ku high-frequency LLC resonant topology uye kuvandudza kushanda zvakanaka kwesimba remachaja ari mubhodhi nekuderedza ESR (equivalent series resistance) uye kuwedzera ripple current resistance.
Semuenzaniso, kushanda zvakanaka kweLKM series muXiaomi charging guns kunoderedza kurasikirwa kwesimba panguva yekuchaja. Izvi zvinogona kutamisirwa kune in-board high-power fast charging scenarion.
4. Kushandira pamwe muindasitiri uye ramangwana
Muenzaniso wekushandira pamwe chete neXiaomi (sekugadzira capacitor yakagadzirwa) unopa muenzaniso webasa remachaja ari mundege. Chikwata chavo chehunyanzvi chakawana kuenzaniswa kwakanyatsojeka kwemacapacitor nemidziyo yemagetsi nekutora chikamu chakasimba mukutsvaga nekugadzira vagadziri vemagetsi (sekushanda pamwe chete nevagadziri vemachip vakaita sePI neInnoscience).
Mune ramangwana, nekuwedzera kukurumbira kwemapuratifomu e800V ane voltage yepamusoro uye tekinoroji yekuchaja zvakanyanya, iri kugadzira capacitor ine simba rakawanda, iyo inotarisirwa kukurudzira kuvandudzwa kwemachaja ari mubhodhi kuti ave akareruka uye akabatana.
Mhedziso
Kubva pamagetsi evatengi kusvika kumunda wemotokari, ma capacitor akaratidza basa guru rema capacitor se "nzvimbo dzekutonga simba" kuburikidza nehunyanzvi hwetekinoroji uye kugadzirisa mamiriro ezvinhu. Kushandira pamwe kwayo neXiaomi Fast Charge hakungopi mhinduro dzinoshanda kumusika wevatengi chete, asiwo kunowedzera simba idzva mukuvandudzwa kwetekinoroji yemachaja ari mubhodhi. Ichitungamirirwa nemotokari itsva dzesimba uye tekinoroji yekuchaja nekukurumidza, tekinoroji ye capacitor diki uye yakavimbika icharamba ichitungamira shanduko muindasitiri.
