Kodi Pali Battery Yamtundu Wanji Yagalimoto Yamagetsi?

Mabatire amagetsi amagetsi ndi gawo limodzi lokwera mtengo kwambiri m'galimoto yamagetsi.

Kukwera mtengo kumatanthauza kuti magalimoto amagetsi ndi okwera mtengo kuposa mitundu ina yamafuta, zomwe zimachepetsa kutengera kwa EV.

Lithiamu-ion
Mabatire a lithiamu-ion ndi omwe amadziwika kwambiri. Popanda kupita mwatsatanetsatane, amachotsa ndikuwonjezeranso pamene electrolyte imanyamula ayoni a lithiamu kuchokera ku anode kupita ku cathode, ndi mosemphanitsa. Komabe, zinthu zomwe zimagwiritsidwa ntchito mu cathode zimatha kusiyana pakati pa mabatire a lithiamu-ion.

LFP, NMC, ndi NCA ndi ma subchemistries atatu osiyana a Lithium-ion mabatire. LFP imagwiritsa ntchito Lithium-phosphate ngati zinthu za cathode; NMC imagwiritsa ntchito Lithium, Manganese, ndi Cobalt; ndipo NCA imagwiritsa ntchito Nickel, Cobalt ndi Aluminium.

Ubwino wa mabatire a Lithium-ion:
● Kupanga kotchipa kuposa mabatire a NMC ndi NCA.
● Utali wamoyo - perekani 2,500-3,000 yozungulira / yotulutsa zonse poyerekeza ndi 1,000 ya mabatire a NMC.
● Patsani kutentha pang'ono pomatchaja kuti mphamvu ikhale yotalikirapo mpaka pa jiko lachaji, zomwe zimapangitsa kuti azithamanga mwachangu popanda kuwonongeka kwa batire.
● Ikhoza kuperekedwa ku 100% ndi kuwonongeka pang'ono kwa batri chifukwa kumathandiza kuwongolera batri ndikupereka zowerengera zolondola zamtundu - Eni ake a Model 3 omwe ali ndi batri ya LFP akulangizidwa kuti asunge malire a 100%.

Chaka chatha, Tesla adapatsa makasitomala ake a Model 3 ku America kusankha pakati pa NCA kapena batire ya LFP. Batire ya NCA inali yopepuka 117kg ndipo idapereka ma 10 mailosi ochulukirapo, koma inali ndi nthawi yayitali yotsogolera. Komabe, Tesla akutsimikiziranso kuti kusiyanasiyana kwa batri la NCA kumangoperekedwa ku 90% ya mphamvu zake. Mwanjira ina, ngati mukufuna kugwiritsa ntchito nthawi zonse, LFP ikhoza kukhala njira yabwinoko.

Nickel-zitsulo hydride
Mabatire a nickel-metal hydride (ofupikitsidwa ku NiMH) ndiwo okhawo omwe ali ndi mabatire a lithiamu-ion omwe ali pamsika, ngakhale kuti nthawi zambiri amapezeka m'magalimoto amagetsi osakanizidwa (makamaka Toyota) mosiyana ndi magalimoto amagetsi oyera.

Chifukwa chachikulu cha izi ndikuti kuchuluka kwamphamvu kwa mabatire a NiMH ndikochepera 40% kuposa mabatire a lithiamu-ion.
