Gukoresha capacitors mu buryo bushya mu gusharija imodoka: Dufatiye urugero ku bufatanye hagati ya Shanghai YMIN na Xiaomi Fast Charge

Bitewe n’iterambere rikomeye ry’isoko rishya ry’ibinyabiziga bikoresha ingufu, charger z’imodoka, nk’imwe mu ngingo z’ingenzi, zirimo gutera imbere zigana ku musaruro mwiza, ubushobozi bwo gukora buhoro no kwizerwa cyane.

Shanghai Electronics Co., Ltd., hamwe n'ikoranabuhanga ryayo rishya rya capacitor, ntifasha Xiaomi Fast Charge kugera ku iterambere mu bijyanye n'ibikoresho by'ikoranabuhanga, ahubwo inatanga inkunga y'ingenzi mu kuvugurura tekiniki ya chargers z'imodoka.

1. Ingano nto n'ubucucike bw'ingufu nyinshi: ubwihindurize bw'ikirere bw'ibikoresho byo gusharija imodoka
Kimwe mu bihangano by'ingenzi bya capacitors kiri mu gishushanyo cyayo cy' "ingano nto, ubushobozi bunini". Urugero, ubwoko bw'icyuma gikozwe mu maziCapacitors z'uruhererekane rwa LKM(450V 8.2μF, ingano ya 8 * 16mm gusa) yakozwe kugira ngo ikoreshe imbunda zo gushyushya za Xiaomi zigira inshingano ebyiri zo gufunga ingufu no kuzigama amashanyarazi binyuze mu kunoza ibikoresho n'imiterere y'imbere.

Iri koranabuhanga rikoreshwa no ku masharubu y'imodoka - mu mwanya muto uri mu bwato, capacitors ntoya zishobora kongera cyane ubucucike bw'imbaraga za module yo gushyushya mu gihe zigabanya umuvuduko wo gukwirakwiza ubushyuhe. Byongeye kandi, seri ya KCX (400V 100μF) na capacitors za NPX series solid-state (25V 1000μF) zagenewe by'umwihariko gusharija vuba bya GaN zatanze ibisubizo bikuze byo guhindura neza DC/DC sharubu ziri mu bwato zifite imiterere yazo ya frequency nyinshi n'impedance nke.

2. Kurwanya ibidukikije bikabije: Ingwate yo kwizera ku bintu biri mu ndege

Imashini zishyushya zigomba kwihanganira imikorere igoye nko guhinda umushyitsi, ubushyuhe bwinshi, n'ubushuhe bwinshi. Capacitors zagenewe kurwanya inkuba n'imiyaga myinshi ikwirakwira cyane. Urugero, LKM series ishobora gukora neza ahantu hari hagati ya -55℃ ~ 105℃ n'igihe cy'ubuzima kigera ku masaha 3000.

Ikoranabuhanga ryayo rya capacitor y’amazi akomeye (nk’iy’umuyoboro urwanya guhindagurika kw’amashanyarazi ukoreshwa mu gushyushya imodoka) ryatsinze icyemezo cya IATF16949 na AEC-Q200 kandi ryakoreshejwe neza mu gushyushya imodoka no mu gushyushya imodoka nshya nka BYD. Ubu buryo bwo kwizerwa ni cyo kintu cy’ingenzi gisabwa kugira ngo shyushya imodoka zikoreshwa mu ndege zihangane n’ibidukikije bikomeye.

3. Imikorere myiza no kunoza ingufu: guhuza ikoranabuhanga rya semiconductor ryo mu cyiciro cya gatatu​
Imiterere y’ibikoresho bya semiconductor byo mu gisekuru cya gatatu nka gallium nitride (GaN) na silicon carbide (SiC) ikoresha frequency nyinshi, ishyira ibisabwa cyane ku buryo frequency nyinshi ikoreshwa n’ibitakara bike bya capacitors.

Uruhererekane rwa KCX rushobora kwihuza na topology ya resonant ya LLC ifite frequency yagutse no kunoza imikorere myiza y'ingufu muri rusange z'ibyuma bitanga ingufu biri mu bwato binyuze mu kugabanya ESR (ubudahangarwa bw'uruhererekane bungana) no kongera ubudahangarwa bw'umuvuduko w'amashanyarazi.

Urugero, uburyo bworoshye bwo koroshya ingufu za LKM mu mbunda zo gushyushya za Xiaomi bugabanya ku buryo butaziguye igihombo cy'ingufu mu gihe cyo gushyushya. Ubu bunararibonye bushobora kwimurirwa mu gihe cyo gushyushya vuba cyane.

4. Ubufatanye mu nganda n'amahirwe y'ejo hazaza
Uburyo bw'ubufatanye bwa Xiaomi (nk'iterambere rya capacitor ryakozwe ku giti cye) butanga icyitegererezo cy'urwego rw'ibikoresho byo gushyushya amashanyarazi biri mu bwato. Itsinda ryayo rya tekiniki ryageze ku guhuza neza capacitors n'ibikoresho by'amashanyarazi binyuze mu kwitabira cyane ubushakashatsi no guteza imbere inganda zitanga amashanyarazi (nk'ubufatanye n'abakora chips nka PI na Innoscience).

Mu gihe kiri imbere, hamwe no gukwirakwiza ikoranabuhanga rya 800V rikoresha ingufu nyinshi ndetse n’ikoranabuhanga rigezweho ryo gushyushya umuriro, hari gukorwa uruhererekane rwa capacitor rufite imbaraga nyinshi, byitezwe ko ruzarushaho guteza imbere iterambere rya chargers ziri mu bwato zigashyirwa mu buryo bworoshye kandi buhuriweho.

Umwanzuro​

Kuva ku bikoresho by'ikoranabuhanga kugeza ku bijyanye n'imodoka, capacitors zagaragaje uruhare runini rwa capacitors nk' "ahantu ho gucunga ingufu" binyuze mu guhanga udushya mu ikoranabuhanga no guhuza ibintu. Ubufatanye bwazo na Xiaomi Fast Charge butanga ibisubizo byiza ku isoko ry'abaguzi gusa, ahubwo bunashyira imbaraga nshya mu kuvugurura ikoranabuhanga rya chargers ziri mu ndege. Bitewe n'imodoka nshya zikoresha ingufu n'ikoranabuhanga ryo gusharija vuba, ikoranabuhanga rya capacitors nto kandi zizewe cyane rizakomeza kuyobora impinduka mu nganda.
