M'zaka zaposachedwa, moto wamagalimoto amagetsi wakhala ukubwera motsatizana, makamaka kutentha kwambiri m'chilimwe, magalimoto amagetsi ndi osavuta kuyatsa ndi kuyambitsa moto!
Malingana ndi gulu la 2021 la gulu lopulumutsira moto lolandirira alamu ndi deta yamoto yomwe inatulutsidwa ndi Bungwe la Fire Rescue Bureau la Ministry of emergency management, pafupifupi moto wa 18000 ndi imfa za 57 chifukwa cha kulephera kwa njinga zamagetsi ndi mabatire awo adanenedwa m'dziko lonse chaka chatha.Akuti moto wa njinga zamagetsi 26 unachitika ku Yantai patangotha theka la chaka chino.
Nchiyani chimachititsa kuti magalimoto amagetsi azichitika pafupipafupi chonchi?
Choyambitsa chachikulu cha kuyaka modzidzimutsa kwa magalimoto amagetsi ndi kuthawa kwamafuta kwa mabatire a lithiamu.Chomwe chimatchedwa kuti thermal runaway ndikuchitapo kanthu chifukwa cha zolimbikitsa zosiyanasiyana.Mtengo wa calorific ukhoza kukweza kutentha kwa batri ndi madigiri masauzande ambiri, kuchititsa kuyaka modzidzimutsa.Mabatire amagetsi amagetsi amatha kuthawa chifukwa cha kuchulukirachulukira, kuphulika, kutentha kwambiri, dera lalifupi, kuwonongeka kwamphamvu kwakunja ndi zifukwa zina.
Momwe mungapewere kuthawa kwamafuta
Zomwe zimayambitsa kutentha kosalamulirika ndizosiyanasiyana.Chifukwa chake, njira zingapo zodzitetezera ziyenera kuchitidwa kuti zisachitike kutentha kosatha.
Choyambitsa chachikulu cha kuthawa kwamafuta ndi "kutentha".Pofuna kupewa kuthawa kwamafuta, ndikofunikira kuwonetsetsa kuti batire yakhala ikugwira ntchito pakutentha koyenera.Komabe, kutentha kwambiri m'chilimwe, "kutentha" sikungalephereke, choncho tiyenera kuyamba ndi batire, kuti batire ya lithiamu-ion ikhale ndi kutentha kwabwino komanso kutentha kwa kutentha.
Choyamba, ogula ayenera kumvetsera makhalidwe oyenera a mabatire a lithiamu pogula magalimoto amagetsi, komanso ngati zipangizo zamkati za maselo a batri zimakhala ndi kutentha kwabwino komanso kutentha kwa kutentha.Kachiwiri, ngati cholumikizira cholumikizidwa ndi batire mkati mwagalimoto yamagetsi chimakhala ndi ntchito yolimbana ndi kutentha kwambiri, tiyenera kuonetsetsa kuti cholumikizira sichidzafewetsa ndikulephera chifukwa cha kutentha kwakukulu, kuti tiwonetsetse kuti dera silikutsekedwa ndikupewa kuchitika kwakanthawi kochepa. dera.
Monga katswiri wodziwa zolumikizira magalimoto amagetsi, Ambuluali ndi zaka 20 zakufufuza ndi chitukuko mu zolumikizira galimoto yamagetsi ya lithiamu, ndipo amapereka njira zothetsera mabizinesi amagetsi amagetsi monga Xinri, Emma, Y.adi, etc. Chojambulira cha Ames galimoto yamagetsi yosagwira kutentha kwambiri imatenga PBT yokhala ndi kutentha kwabwino, kukana kwa nyengo ndi makhalidwe amagetsi.Malo osungunuka a PBT insulating chipolopolo cha pulasitiki ndi 225-235℃.

Zolumikizira zamagalimoto amagetsi otenthetsera kwambiri zadutsa mayeso oletsa moto, ndipo ntchito yoletsa moto imafika ku V0 flame retardant, yomwe imathanso kukumana ndi kutentha kozungulira -20 ℃ ~ 120 ℃.Kuti mugwiritse ntchito m'malo otentha omwe ali pamwambawa, chigoba chachikulu cha cholumikizira galimoto yamagetsi sichingafewe chifukwa cha kutentha kwambiri, zomwe zimapangitsa kuti pakhale kafupi.
Kuphatikiza pa kusankhidwa kwa mabatire ndi zigawo zawo, khalidwe la ma charger amagetsi amagetsi, nthawi yayitali yolipiritsa, kusinthidwa kosaloledwa kwa magalimoto amagetsi, ndi zina zotero ndizofunika kwambiri kuti pakhale chitetezo chamagetsi amagetsi a lithiamu.
