Ukadaulo Wapamwamba wa Batri mu Mafoni Anzeru
Pakati pa moyo wachangu, mafoni a m'manja asintha kukhala zida zomwe nthawi zambiri zimakhala m'manja mwathu. Kuyambira kulankhulana ndi kuyenda mpaka kujambula zithunzi ndi ntchito zakutali mpaka zosangalatsa, chilichonse chimadalira chinthu chimodzi chofunikira: batire. Komabe, mphamvu zomwe zikuchulukirachulukira nthawi zambiri zimatsutsana ndi zofuna za mapangidwe opyapyala komanso otetezeka kwambiri. Chifukwa chake, ukadaulo wa batire mu mafoni a m'manja ukupitilirabe kusintha ndipo ndi gawo limodzi losangalatsa kwambiri la zatsopano mumakampani opanga mafoni.
Kusintha kwa batri: kuchokera ku Li-ion kupita ku ukadaulo wanzeru
Mafoni ambiri amakono amagwiritsabe ntchito mabatire a lithiamu-ion (Li-ion) kapena lithiamu-polymer (Li-Po). Onsewa amachokera ku lithiamu chemistry, koma amasiyana mu kapangidwe ka electrolyte ndi ma phukusi. Li-Po nthawi zambiri imakhala yosinthasintha kwambiri, zomwe zimapangitsa kuti opanga apange mapangidwe a mafoni opyapyala kapena omwe ali ndi malo ovuta mkati. Pakadali pano, Li-ion imadziwika ndi mphamvu zake zambiri komanso ndalama zogwirira ntchito bwino.
Ngakhale kuti njira yogwiritsira ntchito mankhwala ingaoneke ngati "yofanana," zinthu zazikulu zachitika pakupanga maselo, zipangizo zama electrode, kasamalidwe ka kutentha, ndi makina ochajira. Kusintha sikuti nthawi zonse kumakhudza kuchuluka kwa mphamvu ya mAh, koma kumakhudza nthawi yayitali ya batri, moyo wa batri wotetezeka, komanso kutchajira mwachangu popanda kuwononga kwambiri.
Kuwonjezeka kwa mphamvu
Chizindikiro chimodzi chofunikira cha batire ndi kuchuluka kwa mphamvu, komwe ndi kuchuluka kwa mphamvu komwe kungasungidwe mu voliyumu kapena kulemera kwina. Mafoni amakono amafuna malo a makamera, ma module a 5G, makina oziziritsira, ndi zinthu zina. Chifukwa malo amkati ndi ochepa, opanga mabatire akuyang'ana kwambiri pakuwonjezera kuchuluka kwa mphamvu kuti awonjezere mphamvu popanda kuwonjezera kukula kwa batire.
Zatsopano monga ma silicon anode ndi njira yofufuzira yodalirika. Poyerekeza ndi graphite yachikhalidwe, silicon imatha kusunga ma lithiamu ion ambiri, omwe m'malingaliro amatha kuwonjezera mphamvu. Vuto ndilakuti silicon imakonda kukula ndikuchepa panthawi yoyatsira, zomwe zitha kufulumizitsa kuwonongeka. Chifukwa chake, njira zambiri zimaphatikiza silicon ndi graphite kapena kugwiritsa ntchito mapangidwe a anode opangidwa kuti akonze kukhazikika.
Kuchaja mwachangu kwambiri: osati ma watts akulu okha
Kuchaja mwachangu kwakhala chinthu chofala kwambiri. Nthawi zambiri timamva ziwerengero monga 33W, 67W, 120W, ndi zina zambiri pa mitundu ina. Komabe, ukadaulo wapamwamba wa batri sikutanthauza mphamvu yamagetsi yokha. Chofunika kwambiri, ndi momwe mphamvu yamagetsi ndi magetsi zimayendetsedwa kuti zitsimikizire kuti batireyo ndi yotetezeka komanso yokhalitsa.
Mafoni ena a m'manja amagwiritsa ntchito njira ya batire ya maselo awiri, pomwe batire "imagawika" m'magawo awiri omwe amachajidwa nthawi imodzi. Njirayi imalola mphamvu yayikulu yochajira popanda kudzaza selo limodzi. Kuphatikiza apo, ma circuit amakono ochajira amagwiritsa ntchito ma algorithms a sitepe ndi sitepe (monga, mphamvu yokhazikika yotsatiridwa ndi mphamvu yokhazikika) kuti achepetse kutentha, makamaka pamene batire ikuyandikira mphamvu yonse.
Zipangizo zamakono monga ma charge pump ndi dynamic voltage regulation nazonso zimathandiza. Ndi kasamalidwe ka mphamvu kolondola, kutentha kumatha kuchepetsedwa, kugwira ntchito bwino kumawonjezeka, komanso chiopsezo cha kuwonongeka kwa magwiridwe antchito a batri chimachepa.
Kusamalira kutentha: chinsinsi cha chitetezo ndi moyo wautali
Kutentha ndi mdani wamkulu wa batri. Kutentha kwambiri kumathandizira kuti mankhwala azigwiritsidwa ntchito molakwika, kuchepetsa mphamvu, ndipo m'malo ovuta kwambiri, kungayambitse mavuto achitetezo. Chifukwa chake, makina oziziritsira ndi kuwunika kutentha ndi zinthu zofunika kwambiri paukadaulo wamakono wa batri.
Opanga mafoni a m'manja tsopano amadalira masensa oyesera kutentha m'malo osiyanasiyana: mu batri, pa bolodi la amayi, komanso pafupi ndi chipset. Ndi deta iyi, makina amatha kusintha liwiro la kuchaja, kuchepetsa magwiridwe antchito kwakanthawi, kapena kuyimitsa njirayi kutentha kukapitirira malire otetezeka.
Kuwonjezera pa masensa, zipangizo zoziziritsira zasinthanso: zipinda zotenthetsera, mapepala a graphite, ma thermal gels, komanso mapangidwe amkati mwa chimango chomwe chimathandiza kuchotsera kutentha. Zonsezi cholinga chake ndi kusunga batri pamalo abwino kwambiri otenthetsera, nthawi zonse ikadzala mofulumira komanso ikagwiritsidwa ntchito kwambiri, monga kusewera masewera.
Mabatire "okhalitsa" kudzera mu mapulogalamu ndi AI
Ukadaulo wapamwamba wa batri si wa zida zokha. Machitidwe ogwiritsira ntchito tsopano akutenga gawo lofunika kwambiri pakukulitsa moyo wa batri tsiku ndi tsiku ndikuchepetsa kuwonongeka kwa nthawi yayitali. Mafoni ambiri anzeru amapereka zinthu monga:
1. Batri Yosinthika: imaphunzira momwe pulogalamu imagwiritsira ntchito ndikuchepetsa zochita zosafunikira zakumbuyo.
2. Kuchaja Kwabwino Kwambiri: kumasunga chaji pafupifupi 80–90% ndipo kumamaliza wogwiritsa ntchito asanadzuke, zomwe zimachepetsa nthawi yomwe batire ili pa 100% (zomwe zingathandize kuti mankhwala ayambe kukalamba msanga).
3. Kusamalira Thanzi la Batri: imayang'anira thanzi la batri kutengera nthawi yochajira, kutentha, ndi momwe imagwiritsidwira ntchito, kenako imasintha njira zochajira.
Mothandizidwa ndi AI, mafoni amatha kulinganiza bwino momwe ogwiritsa ntchito amagwiritsira ntchito komanso nthawi ya batri. Mwachitsanzo, foni ikazindikira kuti wogwiritsa ntchito nthawi zambiri safuna chaji yonse, dongosololi limatha kuchepetsa chaji yayikulu kuti batire lizitha kugwira ntchito nthawi yayitali.
Ukadaulo wamakono woteteza ndi kuteteza
Chitetezo cha mabatire ndi nkhani ya anthu onse chifukwa zochitika za mabatire olakwika zimatha kukhala ndi zotsatirapo zoopsa. Mafoni amakono amagwiritsa ntchito njira zosiyanasiyana zotetezera, kuphatikizapo:
– Chitetezo cha mphamvu yowonjezereka ndi mphamvu yowonjezereka: chimaletsa mphamvu yowonjezereka ndi mphamvu yowonjezereka.
- Chitetezo ku kutentha kwambiri: chimasiya kuyatsa pamene kutentha sikuli kotetezeka.
– Cholekanitsa ndi zinthu zokhazikika: chimaletsa ma circuit afupi amkati.
– Dongosolo loyang'anira mabatire (BMS): “ubongo” womwe umawongolera momwe batire ilili komanso kulinganiza zosowa za mphamvu.
BMS pa mafoni a m'manja tsopano ndi yanzeru kwambiri, osati kungowonetsa kuchuluka kwa batri, komanso kuwongolera momwe amachajira, kuyang'anira mphamvu ya selo lililonse (makamaka pa mapangidwe a maselo awiri), komanso nthawi ndi nthawi kuwerengera mphamvu yoyerekeza.
Zochitika zatsopano: mabatire olimba komanso tsogolo la mafoni a m'manja
Chimodzi mwa nkhani zomwe zimakambidwa kwambiri ndi mabatire olimba (mabatire okhala ndi ma electrolyte olimba). Ukadaulo uwu umatamandidwa chifukwa cha kuchuluka kwa mphamvu zake, chiopsezo chotsika cha moto, komanso moyo wautali. Komabe, kupeza mabatire olimba a mafoni a m'manja kumakumanabe ndi mavuto monga kupanga zinthu zambiri, mtengo wake, komanso kukhazikika kwa zinthu.
Kupatula pa solid-state, kafukufuku wina akuphatikizapo:
– Sodium-ion (natrium-ion): maziko ake ndi ochuluka komanso otsika mtengo, koma mphamvu zake zimakhalabe pansi pa lithiamu.
- Ukadaulo wobwezeretsanso mabatire: kukonza njira yopezeranso zinthu zamtengo wapatali kuti zikhale zotetezeka kwa chilengedwe.
- Kapangidwe ka modular ndi kuthekera kokonzanso: kukakamiza kuti mabatire asinthidwe mosavuta popanda kuwononga kukana kwa madzi.
Ngati izi zipitirira kukula, mafoni a m'manja amtsogolo angakhale ndi moyo wautali wa batri, zaka zambiri za moyo wa batri popanda kuwonongeka kwakukulu, komanso kuyitanitsa mwachangu kwambiri koma kotetezeka.
Mapeto
Ukadaulo wapamwamba wa batri mu mafoni a m'manja ndi kuphatikiza kwa zatsopano mu zipangizo, kapangidwe ka maselo, machitidwe ochaja mwachangu, kasamalidwe ka kutentha, ndi luntha la mapulogalamu. Ngakhale mabatire a lithiamu akadali otsogola, kusintha kukupangidwa pafupifupi mbali iliyonse yomwe imatsimikiza zomwe ogwiritsa ntchito akukumana nazo: kuyambira kupirira kwa tsiku ndi tsiku ndi nthawi yochaja mpaka chitetezo ndi moyo wautali. Ndi kafukufuku wa ma silicon anode, kasamalidwe ka chaja kozikidwa pa AI, komanso kuthekera kwa tsogolo lolimba, mabatire a mafoni a m'manja apitiliza kukhala malo opangira zatsopano zomwe zidzatsimikizire momwe zida zathu zingakwaniritsire zosowa za moyo wamakono.
Ngati mukufuna, nditha kusintha nkhaniyi kuti igwirizane ndi omvera enaake (ophunzira, onse, kapena akatswiri), kuwonjezera deta yofananira (monga mphamvu yochaja ndi momwe imakhudzira), kapena kupanga mtundu wautali wokhala ndi mitu yaying'ono ndi maumboni.
