Dab tsi yog cov roj teeb muaj zog ntau lithium-ion? Yam koj yuav tsum paub

Txoj kev caij tsheb kauj vab hluav taws xob, cov hluav taws xob cov teeb hluav taws xob tau muaj hluav taws xob kev txaus siab tau txais kev txaus siab lithium-ion roj teeb. Cov roj teeb no tau tsim los khaws ntau lub zog, ua rau siv tau ntxiv yam tsis muaj kev rov qab siv dua. Txawm hais tias koj muaj hwj chim siv Ebike rau txhua hnub lossis chaw pw hav zoov rau cov teeb meem kev taug txuj kev nyuaj, nkag siab txog cov peev txheej muaj peev xwm siab yog qhov tseem ceeb. Kab lus no piav qhia qhov muaj peev xwm tshaj plaws ntawm kev ua lag luam thiab cov kev nkag siab los pab koj xaiv cov roj teeb uas phim koj cov kev cai tshwj xeeb.

Dab tsi yog "muaj peev xwm siab tshaj plaws" txhais tau tias muaj roj teeb lithium-ion?

Roj teeb muaj peev xwm ntsuas cov nyiaj fais fab muaj peev xwm khaws, feem ntau yog qhia hauv Milliampere-teev (MHAth) rau cov neeg lub hlwb lossis cov khoom siv) rau cov tshuab loj. Lub zog roj teeb muaj zog ntau dua rau nws qhov loj me lossis qhov hnyav, ua rau nws zoo tagnrho rau cov ntawv thov runtimes.

Tshaj muaj peev xwm, lwm yam cuam tshuam nrog kev ua tau zoo:

• Kev tso tawm tam sim no (ntsuas hauv amps, lossis chancess mus ntaus nqi, cdr): txiav txim seb lub zog roj npaum li cas tuaj yeem xa tau ib zaug.
• Nominal voltage: feem ntau 3.6V-3.7v rau cov kua qaub.
