Zeziphi Iintlobo zebhetri yeMoto yoMbane ezikhoyo?

Iibhetri zeemoto zombane lelona candelo libiza kakhulu kwimoto yombane.

Ithegi yexabiso eliphezulu ithetha ukuba iimoto zombane zibiza kakhulu kunezinye iintlobo zamafutha, nto leyo ethoba isantya sokwamkelwa kwe-EV.

I-Lithium-ion
Iibhetri zeLithium-ion zezona zidumileyo. Ngaphandle kokungena kwiinkcukacha ezininzi, bakhupha kwaye bahlaziye njengoko i-electrolyte ithwala i-lithium ion echajiwe kakuhle ukusuka kwi-anode ukuya kwi-cathode, kwaye ngokuphambene noko. Nangona kunjalo, izinto ezisetyenziswe kwi-cathode zinokuhluka phakathi kweebhetri ze-lithium-ion.

I-LFP, i-NMC, kunye ne-NCA zii-sub-chemistries ezintathu ezahlukeneyo zeebhetri ze-Lithium-ion. I-LFP isebenzisa i-Lithium-phosphate njengesixhobo se-cathode; I-NMC isebenzisa iLithium, iManganese, kunye neCobalt; kunye neNCA isebenzisa iNickel, iCobalt kunye neAluminium.

Izibonelelo zeebhetri zeLithium-ion:
● Ukuvelisa ngexabiso eliphantsi kuneebhetri ze-NMC neNCA.
● Ubomi obude - hambisa i-2,500-3,000 intlawulo epheleleyo / imijikelo yokukhupha xa kuthelekiswa ne-1,000 yeebhetri ze-NMC.
● Veza ubushushu obuncinane ngexesha lokutshaja ukuze kukwazi ukugcina umlinganiselo ophezulu wamandla ixesha elide kwijiko lokutshaja, okukhokelela kwintlawulo ekhawulezayo ngaphandle kokonakala kwebhetri.
● Inokuhlawuliswa kwi-100% ngomonakalo omncinci webhetri njengoko inceda ukulinganisa ibhetri kunye nokubonelela ngoqikelelo oluchanekileyo oluchanekileyo - abanikazi beModel 3 kunye nebhetri ye-LFP bayacetyiswa ukuba bagcine umda wentlawulo obekwe kwi-100%.

Kunyaka ophelileyo, uTesla wanikezela ngeModel 3 abathengi eMelika ukhetho phakathi kweNCA okanye ibhetri yeLFP. Ibhetri ye-NCA yayikhaphukhaphu nge-117kg kwaye ibonelela ngeemayile ezili-10 ngakumbi, kodwa yayinexesha elide lokukhokela. Nangona kunjalo, uTesla ukwacebisa ukuba ibhetri yeNCA ihlawuliswe kuphela kwi-90% yomthamo wayo. Ngamanye amazwi, ukuba uceba ukusebenzisa rhoqo uluhlu olupheleleyo, i-LFP isenokuba lolona khetho lungcono.

I-Nickel-metal hydride
Iibhetri ze-nickel-metal hydride (ezifinyeziweyo kwi-NiMH) zizona kuphela ezinye iibhetri ze-lithium-ion ezikhoyo ngoku kwimarike, nangona zihlala zifumaneka kwiimoto zombane ze-hybridi (ininzi iToyota) ngokuchasene neenqwelo zombane ezicocekileyo.

Isizathu esona sizathu salokhu kukuba ubuninzi bamandla beebhetri ze-NiMH bufana ne-40% ephantsi kuneebhetri ze-lithium-ion.
