Chiyambi:
Masiku ano, kuteteza chilengedwe ndi ukadaulo, magalimoto amagetsi akutchuka kwambiri ndipo adzalowa m'malo mwa magalimoto achikhalidwe amafuta mtsogolo.batri ya lithiamundiye mtima wa galimoto yamagetsi, zomwe zimapereka mphamvu yofunikira kuti galimoto yamagetsi ipite patsogolo. Moyo wautumiki ndi chitetezo cha mabatire amagetsi ndi nkhani zomwe eni magalimoto amakhudzidwa nazo kwambiri. Komabe, nkhani ziwirizi zikugwirizana kwambiri ndi njira yoyenera yolipirira. Mabatire omwe amagwiritsidwa ntchito m'magalimoto amagetsi tsopano akuphatikizapo mabatire a lithiamu ternary ndi mabatire a lithiamu iron phosphate. Kodi njira ziwirizi zikhudza bwanji mabatire awiriwa? Tiyeni tikambirane pamodzi.
Zotsatira za kugwiritsa ntchito mabatire a lithiamu atatu kenako n’kuwachaja
1. Kuwonongeka kwa mphamvu: Nthawi iliyonse mphamvu ya batri ya lithiamu ya ternary ikagwiritsidwa ntchito ndikuyiyikanso, imakhala yotulutsa madzi ambiri, zomwe zingayambitse kuti mphamvu ya batri ya lithiamu ya ternary iwonongeke pang'onopang'ono, nthawi yochajira ifupike, komanso kuti liwiro loyendetsa lichepe. Mwachitsanzo, wina wachita kafukufuku. Batri ya lithiamu ya ternary ikatulutsidwa madzi ambiri nthawi 100, mphamvu imachepa ndi 20% ~ 30% poyerekeza ndi mtengo woyambira. Izi zili choncho chifukwa chakuti kutulutsa madzi ambiri kumayambitsa kuwonongeka kwa zinthu za electrode, kuwonongeka kwa electrolyte, ndi chitsulo cha lithiamu chomwe chimawononga mphamvu ya batri komanso mphamvu yotulutsa madzi, zomwe zimapangitsa kuti mphamvu ichepe, ndipo kuwonongeka kumeneku sikungasinthe.
2. Kufupikitsa nthawi ya moyo: Kutulutsa madzi ambiri kudzathandiza kuti zinthu zamkati mwa batire ya lithiamu ya ternary ziyambe kukalamba, kuchepetsa mphamvu ya batire ndi kutulutsa madzi, kuchepetsa kuchuluka kwa mphamvu ya batire ndi kutulutsa madzi, ndikufupikitsa nthawi ya ntchito.
3. Kuchepetsa mphamvu ya chaji ndi kutulutsa mphamvu: Kugwiritsa ntchito mphamvu yowonjezera kenako kubwezeretsanso mphamvu kudzapangitsa kuti ma electrode abwino ndi oipa a batire ya lithiamu ya ternary agawanike, kuwonjezera kukana kwa mkati mwa batire, kuchepetsa mphamvu ya chaji, kukulitsa nthawi yochaji, kuchepetsa mphamvu ya batire, ndikuchepetsa kwambiri mphamvu ya batire.
4. Kuwonjezeka kwa zoopsa zachitetezo: Kutuluka kwa madzi ambiri kwa nthawi yayitali kungayambitse ma plates amkati mwa ternarybatri ya lithiamukusokoneza kapena kusweka, zomwe zimapangitsa kuti batire isamayende bwino komanso kuti iwonongeke. Kuphatikiza apo, kutulutsa batire mozama kumawonjezera kukana kwake mkati, kumachepetsa mphamvu yochaja, komanso kumawonjezera kutentha komwe kumachitika panthawi yochaja, zomwe zingayambitse batire ya lithiamu ya ternary kuphulika ndi kusokonekera, komanso kuyambitsa kutentha, zomwe zimapangitsa kuti batire ya lithiamu ya ternary iphulike ndi kusokonekera, komanso kuyambitsa kuphulika ndi moto.
Batire ya lithiamu ya Ternary ndi batire yamagetsi yopepuka komanso yodzaza mphamvu kwambiri, ndipo nthawi zambiri imagwiritsidwa ntchito m'magalimoto amagetsi apamwamba. Pofuna kupewa zotsatira zoyipa za kutulutsa madzi ambiri pa batire, batireyo ili ndi bolodi loteteza. Volti ya batire ya lithiamu imodzi yodzaza ndi mphamvu zonse ndi pafupifupi 4.2 volts. Volti imodzi ikatulutsidwa kufika pa 2.8 volts, bolodi loteteza limadula magetsi okha kuti batire isatulutse mphamvu zambiri.
Kuchuluka kwa mphamvu ya chaji mukamagwiritsa ntchito mabatire a lithiamu atatu
Ubwino wochaja pamene mukupita ndikuti mphamvu ya batri ndi ya kuchaja pang'ono ndi kutulutsa pang'ono, ndipo nthawi zonse imakhala ndi mphamvu zambiri kuti ipewe zotsatira zoyipa za mphamvu yochepa pa batri. Kuphatikiza apo, kuchaja pang'ono ndi kutulutsa pang'ono kumathanso kusunga ntchito ya ma lithiamu ion mkati mwa ternary.batri ya lithiamu, kuchepetsa bwino liwiro la kukalamba kwa batri, ndikuwonetsetsa kuti batriyo ikhoza kutulutsa mphamvu mokhazikika panthawi yogwiritsa ntchito pambuyo pake, komanso kungakulitse moyo wa batri. Pomaliza, kuyatsa pamene mukupita kungathandize kuonetsetsa kuti batriyo nthawi zonse imakhala ndi mphamvu zokwanira ndikuwonjezera kuchuluka kwa mayendedwe.
Zotsatira za kubwezeretsanso mphamvu pambuyo pogwiritsa ntchito mabatire a lithiamu iron phosphate
Kuchajanso pambuyo pogwiritsa ntchito ndi kutulutsa madzi ambiri, komwe kudzakhalanso ndi zotsatirapo zoyipa pa kapangidwe ka mkati mwa mabatire a lithiamu iron phosphate, zomwe zimapangitsa kuti zinthu zamkati mwa batire ziwonongeke, kufulumizitsa kukalamba kwa batire, kuwonjezera kukana kwa mkati, kuchepetsa kuyatsa ndi kutulutsa mphamvu, komanso kukulitsa nthawi yochaja. Kuphatikiza apo, pambuyo potulutsa madzi ambiri, mphamvu ya mankhwala ya batire imakula ndipo kutentha kumawonjezeka kwambiri. Kutentha komwe kumapangidwa sikutha pakapita nthawi, zomwe zingayambitse mosavuta batire ya lithiamu iron phosphate kuphulika ndi kusokonekera. Batire yotupa siingapitirire kugwiritsidwa ntchito.
Zotsatira za kuyitanitsa pamene mukugwiritsa ntchito lithiamu iron phosphate
Malinga ndi kutchaja ndi kutulutsa kwabwinobwino, mabatire a lithiamu iron phosphate amatha kuchajidwa ndi kutulutsidwa nthawi zoposa 2,000. Ngati kuchajidwa komwe mukupita komwe kukufunika ndi kutchaja pang'ono komanso kutulutsa pang'ono, moyo wa mabatire a lithiamu iron phosphate ukhoza kukulitsidwa mpaka pamlingo wapamwamba kwambiri. Mwachitsanzo, batire ya lithiamu iron phosphate imatha kuchajidwa ndi kutulutsidwa kuyambira 65% mpaka 85% ya mphamvu, ndipo nthawi yochaja ndi kutulutsa mphamvu imatha kufika nthawi zoposa 30,000. Chifukwa kutulutsa pang'ono kumatha kusunga mphamvu ya zinthu zomwe zimagwira ntchito mkati mwa batire ya lithiamu iron phosphate, kuchepetsa kukalamba kwa batire, ndikuwonjezera moyo wa batire mpaka pamlingo wapamwamba kwambiri.
Vuto lake ndilakuti batire ya lithiamu iron phosphate ili ndi kusakhazikika koipa. Kuchaja ndi kutulutsa madzi pang'ono pafupipafupi kungayambitse cholakwika chachikulu mu voltage ya maselo a batire ya lithiamu iron phosphate. Kusonkhanitsa kwa nthawi yayitali kungapangitse batire kuwonongeka nthawi imodzi. Mwachidule, pali cholakwika mu voltage ya batire pakati pa selo iliyonse. Mtengo wa cholakwika umaposa mulingo wabwinobwino, zomwe zidzakhudza magwiridwe antchito, mtunda ndi moyo wautumiki wa paketi yonse ya batire.
Mapeto
Kudzera mu kusanthula koyerekeza komwe kwachitika pamwambapa, kuwonongeka komwe kumachitika chifukwa cha kuyatsa mabatire awiriwa mphamvu ya batri ikatha sikungasinthe, ndipo njira iyi siyoyenera. Kuyatsa mukamagwiritsa ntchito ndikothandiza kwa batri, ndipo zotsatira zoyipa zomwe zimachitika chifukwa chabatri ya lithiamundi yaying'ono, koma si njira yolondola yolipirira. Izi zikuwonetsa njira yolondola yolipirira kuti muwonjezere chitetezo cha kugwiritsa ntchito batri ndikuwonjezera moyo wautumiki.
1. Pewani kutulutsa mphamvu mopitirira muyeso: Pamene choyezera mphamvu cha galimoto yamagetsi chikuwonetsa kuti mphamvu ya batri yatsala ndi 20 ~ 30%, mutatha kugwiritsa ntchito galimoto nthawi yachilimwe, pitani kumalo ochajirira kuti batriyo izizire kwa mphindi 30 mpaka ola limodzi musanachajire, zomwe zingapewe kutentha kwa chaji ya batri kuti kusakhale kokwera kwambiri, komanso kupewa zotsatira zoyipa za kutulutsa mphamvu mozama pa batri.
2. Pewani kudzaza kwambiri: Mphamvu ya batri yatsala ndi 20~30%. , Zimatenga pafupifupi maola 8~10 kuti igwire bwino ntchito. Ndikofunikira kuti magetsi azimitsidwe magetsi akadzafika pa 90% malinga ndi chiwonetsero cha mita yamagetsi, chifukwa kudzaza mpaka 100% kudzawonjezera kutentha ndipo zoopsa zachitetezo zidzawonjezeka kwambiri, kotero magetsi amatha kuzimitsidwa akadzafika pa 90% kuti apewe zotsatira zoyipa za njirayi pa batri. Mabatire a lithiamu iron phosphate amatha kuzimitsidwa mpaka 100%, koma ziyenera kudziwika kuti magetsi ayenera kuzimitsidwa pakapita nthawi atadzazitsidwa mokwanira kuti apewe kudzaza kwambiri ntchito.
