Kodi Pali Mitundu Yanji ya Mabatire a Galimoto Yamagetsi?

Mabatire a galimoto yamagetsi ndi chinthu chimodzi chokwera mtengo kwambiri m'galimoto yamagetsi.

Mtengo wake wokwera umatanthauza kuti magalimoto amagetsi ndi okwera mtengo kuposa mitundu ina yamafuta, zomwe zikuchepetsa kugwiritsa ntchito magalimoto amagetsi ambiri.

Lithiamu-ion
Mabatire a lithiamu-ion ndi otchuka kwambiri. Popanda kufotokoza zambiri, amatulutsa ndi kuyikanso mphamvu chifukwa electrolyte imanyamula ma ayoni a lithiamu omwe ali ndi mphamvu yabwino kuchokera ku anode kupita ku cathode, ndipo mosemphanitsa. Komabe, zipangizo zomwe zimagwiritsidwa ntchito mu cathode zimatha kusiyana pakati pa mabatire a lithiamu-ion.

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

Ubwino wa mabatire a Lithium-ion:
● Yotsika mtengo kupanga kuposa mabatire a NMC ndi NCA.
● Moyo wautali - imapereka ma cycle 2,500-3,000 a chaji/kutulutsa mphamvu zonse poyerekeza ndi mabatire 1,000 a NMC.
● Pangani kutentha kochepa mukadzachaja kuti ikhale ndi mphamvu zambiri nthawi yayitali mu curve ya chaji, zomwe zimapangitsa kuti chaji ichepe mwachangu popanda kuwonongeka kwa batri.
● Ikhoza kuchajidwa mpaka 100% popanda kuwonongeka kwakukulu kwa batri chifukwa zimathandiza kulinganiza bwino batri ndikupereka ziyerekezo zolondola za kutalika kwa batri - Eni ake a Model 3 omwe ali ndi batri ya LFP akulangizidwa kuti asunge malire a chaji mpaka 100%.

Chaka chatha, Tesla idapatsa makasitomala ake a Model 3 ku America mwayi wosankha pakati pa batire ya NCA kapena LFP. Batire ya NCA inali yopepuka 117kg ndipo inali ndi mtunda wautali wa makilomita 10, koma inali ndi nthawi yayitali yotsogola. Komabe, Tesla imalimbikitsanso kuti batire ya NCA ikhale ndi 90% yokha ya mphamvu yake. Mwanjira ina, ngati mukufuna kugwiritsa ntchito batire yonse nthawi zonse, LFP ikhoza kukhala njira yabwino kwambiri.

Hydride yachitsulo cha nikeli
Mabatire a nickel-metal hydride (ofupikitsidwa kukhala NiMH) ndi omwe amagwiritsidwa ntchito m'malo mwa mabatire a lithiamu-ion omwe ali pamsika pakadali pano, ngakhale kuti nthawi zambiri amapezeka m'magalimoto amagetsi osakanikirana (makamaka Toyota) m'malo mwa magalimoto amagetsi okha.

Chifukwa chachikulu cha izi ndichakuti mphamvu ya mabatire a NiMH ndi yotsika ndi 40% kuposa mabatire a lithiamu-ion.
