Mwachidule za kulipiritsa magalimoto amphamvu zatsopano

Zigawo za batri

1.1 Mphamvu ya batri

Mphamvu ya batri ndi kilowatt-hour (kWh), yomwe imadziwikanso kuti "digiri". 1kWh amatanthauza "mphamvu yogwiritsidwa ntchito ndi chipangizo chamagetsi chokhala ndi mphamvu ya 1 kilowatt kwa ola limodzi." Kuti timvetsetse, nkhani yapagulu iyi nthawi zambiri imagwiritsa ntchito "digiri" kufotokoza. Owerenga amangofunika kudziwa kuti ndi gawo la mphamvu zamagetsi ndipo safunikira kufufuza tanthauzo lake.

[Chitsanzo] Mphamvu za batri zamagalimoto ndi ma SUV okhala ndi mtunda wa 500km ndi pafupifupi madigiri 60 ndi madigiri 70 motsatana. Panopa magalimoto amagetsi oyera opangidwa mochuluka amatha kukhala ndi mabatire omwe amatha kupitilira 150 kwh komanso kuyendetsa mongoyerekeza mpaka 1,000km.

Pali chikwangwani chokhala ndi chidziwitso chagalimoto pachitseko chakumanja chakumanja (kapena chitseko chakumbuyo chakumanja) chagalimoto yatsopano yamagetsi. Digiri ya batri imawerengedwa pogwiritsa ntchito voliyumu yovotera × mphamvu yovotera/1000. Zotsatira zowerengeredwa zitha kukhala zosiyana pang'ono ndi mtengo wakampani yamagalimoto.

1.2 SOC

SOC ndiye chidule cha "State of charge", zomwe zimatanthawuza momwe batire ilili, ndiye kuti, mphamvu yotsalira ya batri, nthawi zambiri imawonetsedwa ngati peresenti.

1.3 Mtundu wa batri

Magalimoto ambiri amagetsi atsopano pamsika amagwiritsa ntchito mabatire a lithiamu-ion, omwe amatha kugawidwa kukhala mabatire a lithiamu iron phosphate ndi mabatire a ternary lithiamu.

Pakati pawo, pali mawonetseredwe awiri enieni a "osakhazikika" a lithiamu iron phosphate mabatire. Choyamba, chiwonetsero cha SOC sichabwino: mwachitsanzo, wolemba posachedwapa adakumana ndi Xpeng P5, yomwe idatenga mphindi 50 kuti ipereke ndalama kuchokera ku 20% mpaka 99%, pomwe ikulipiritsa kuchokera ku 99% mpaka Idatenga mphindi 30 kuti ifike 100%, zomwe zikuwonekeratu. vuto ndi chiwonetsero cha SOC; chachiwiri, liwiro la mphamvu-pansi silili lofanana (lomwe limapezekanso makamaka pamene likuyendetsedwa bwino): magalimoto ena amasonyeza kuti palibe kusintha kwa batri pambuyo pa kuyendetsa 10km mutayimitsidwa kwathunthu, pamene magalimoto ena samatero. Moyo wa batri unatsikira ku 5km pambuyo pa masitepe ochepa chabe. Chifukwa chake, mabatire a lithiamu iron phosphate ayenera kulipiritsidwa mokwanira kamodzi pa sabata kuti akonze kugwirizana kwa maselo.

M'malo mwake, chifukwa cha momwe zinthu ziliri, mabatire a ternary lithiamu sali oyenera kuyimitsidwa atayimitsidwa kwathunthu (koma amatha kupitiliza kuyendetsa mpaka 90% atangoyimitsidwa kwathunthu).Kuonjezera apo, ziribe kanthu kuti ndi batire yamtundu wanji, sayenera kuyendetsedwa pansi pa batire yotsika (SOC <20%), komanso sayenera kuimbidwa m'malo ovuta kwambiri (kutentha pamwamba pa 30 ° C kapena pansi pa 0 ° C).

Malinga ndi liwiro lothamangitsira, njira zolipirira zitha kugawidwa m'kuthamangitsa mwachangu komanso pang'onopang'ono.

(1)Kuthamangitsa mwachangu

Mphamvu yolipirira yothamangitsa mwachangu nthawi zambiri imakhala mphamvu yogwiritsira ntchito magalimoto amagetsi (makamaka mozungulira 360-400V). M'magulu amphamvu kwambiri, zamakono zimatha kufika 200-250A, zofanana ndi 70-100kW mphamvu. Mitundu ina yokhala ndi charger monga malo ogulitsa imatha kufika 150kW kudzera mumagetsi apamwamba. pamwamba. Magalimoto ambiri amatha kulipira kuyambira 30% mpaka 80% mu theka la ola.

[Mwachitsanzo] Kutenga galimoto yokhala ndi batri yokwanira madigiri 60 (yokhala ndi pafupifupi 500km) mwachitsanzo, kuthamanga mwachangu (mphamvu 60kW) kumathalembani batiremoyo wa 250km mu theka la ola (mphamvu yamphamvu)
