Chiyambi cha Battery
M'gawo la batri, mitundu itatu yayikulu ya batri imagwiritsidwa ntchito kwambiri ndikuwongolera msika: cylindrical, square and pouch. Maselo amtunduwu ali ndi mawonekedwe apadera ndipo amapereka maubwino osiyanasiyana. M'nkhaniyi, tiwona mawonekedwe amtundu uliwonse wa selo ndikuyerekeza kutengera zinthu zosiyanasiyana.
1. Battery ya Cylindrical Core
Ubwino:
- Okhwima komanso otsika mtengo: Mabatire a cylindrical akhala akupanga mafakitale kwazaka zopitilira 20, ndi njira zopangira okhwima komanso kuchita bwino kwambiri. Izi zikutanthauza kutsika mtengo komanso zokolola zapamwamba poyerekeza ndi mitundu ina ya maselo.
- Kudalirika kopambana ndi chitetezo: Mabatire a Cylindrical amapereka kudalirika kwambiri komanso chitetezo chifukwa cha njira zawo zopangira zoyesedwa kwambiri komanso chosungira chachitsulo kuti chitetezedwe.
Zoyipa:
- Kulemera kwake ndi kukula kwake: Chophimba chachitsulo chomwe chimagwiritsidwa ntchito m'mabatire a cylindrical chimawonjezera kulemera, zomwe zimapangitsa kuti mphamvu ikhale yochepa poyerekeza ndi mitundu ina ya batri. Kuphatikiza apo, mawonekedwe a cylindrical amapangitsa kuti malo azikhala ochepa.
- Kuchuluka kocheperako: Thermal conductivity of thermal conductivity of cylindrical batteries imachepetsa kuchuluka kwa zigawo zokhotakhota, zomwe zimapangitsa kuti munthu akhale wocheperako. Izi zimapangitsa kuti ma EV agwiritse ntchito omwe amafunikira mabatire angapo, zomwe zimawonjezera zovuta ndipo zimatha kusokoneza kulumikizana.
2. Square batri
Ubwino:
- Chitetezo chowonjezereka: mabatire a square amapangidwa ndi aluminum alloy kapena chitsulo chosapanga dzimbiri, omwe amapereka chitetezo chabwinoko poyerekeza ndi mabatire amthumba. Izi zimathandizira chitetezo cha batri.
- Mapangidwe osavuta komanso ocheperako: Batire yayikulu ili ndi mawonekedwe osavuta ndipo imagwiritsa ntchito zida zopepuka. Poyerekeza ndi mabatire a cylindrical, imakhala ndi mphamvu zambiri komanso kulemera kwake. Izi zimachepetsa kuchuluka kwa ma cell omwe amafunikira gawo la batri ndikuchepetsa zofunikira pamayendedwe owongolera batri (BMS).
Zoyipa:
- Kusakhazikika: Mitundu yambiri yama batire amsika pamsika imapangitsa kuti kukhazikikako kukhale kovuta. Izi zitha kupangitsa kuti ma automation achepetse, kusiyana kwakukulu pakati pa ma cell amtundu uliwonse, komanso moyo wamfupi wa batire.
3. Battery ya thumba
Ubwino:
- Chitetezo chowonjezereka: Mabatire am'matumba amapakidwa mufilimu ya aluminiyamu-pulasitiki, yomwe imachepetsa kuthekera kwa kuphulika poyerekeza ndi ma casing olimba omwe amagwiritsidwa ntchito mumitundu ina ya batri.
- Kuchulukana kwamphamvu: mabatire am'matumba ndi opepuka, 40% opepuka kuposa mabatire achitsulo amtundu womwewo, ndi 20% kupepuka kuposa mabatire a aluminiyamu. Izi zimabweretsa kuchuluka kwa mphamvu zamagetsi.
Zoyipa:
- Kukhazikika ndi zovuta zamtengo: mabatire am'matumba amakumana ndi zovuta kuti akwaniritse zofunikira, zomwe zimapangitsa kukwera mtengo. Kuphatikiza apo, kudalira kwambiri mafilimu opangidwa ndi aluminiyamu-pulasitiki komanso kutsika pang'ono kumabweretsa zovuta kwa opanga mabatire amatumba.
Fotokozerani mwachidule
Mtundu uliwonse wa batri (cylindrical, square, ndi pouch) uli ndi zabwino ndi zovuta zake. Ma cell a cylindrical ndi otsika mtengo ndipo amapereka kusasinthika kwabwino, pomwe ma cell a prismatic amapereka chitetezo chowonjezereka komanso zomangamanga zosavuta. Mabatire a mthumba amapereka mphamvu zambiri koma amakumana ndi zovuta zokhazikika komanso mtengo wake. Kusankhidwa kwa mtundu wa batri kumadalira zinthu monga katundu wakuthupi, zofunikira pakugwiritsa ntchito ndi ndondomeko ya malonda. Mosasamala mtundu wa ma cell, chitetezo ndi nkhani yofunika kwambiri ndipo kutsata miyezo yoyenera yachitetezo ndikofunikira.
