Lub roj teeb muaj peev xwm yog dab tsi?
Roj teeb muaj peev xwm yog categorized rau hauv rated peev thiab lub peev xwm tiag tiag. Rated peev yog hais txog qhov tsawg kawg nkaus ntawm hluav taws xob lub roj teeb yuav tsum tso tawm raws li cov xwm txheej, raws li tau hais tseg thaum nws tsim thiab tsim khoom. IEC cov qauv ntsuas lub peev xwm ntawm nickel-cadmium thiab nickel-hlau hydride roj teeb raws li cov hluav taws xob tawm ntawm 0.2C txog 1.0V tom qab them nyiaj ntawm 0.1C rau 16 teev ntawm 20℃± 5℃. Qhov no txhais tau tias yog C5. Rau cov roj teeb lithium{12}}ion roj teeb, lub peev xwm ntsuas tau teev tseg raws li tus nqi hluav taws xob tawm ntawm 0.2C txog 1.0V tom qab them nyiaj ntawm 1C rau 3 teev nyob rau hauv qhov hluav taws xob tas li (4.2V) tswj ntawm chav tsev kub thiab cov xwm txheej tam sim no. (1C) mus tas li qhov hluav taws xob (4.2V) rau 3 teev, tom qab ntawd tawm ntawm 0.2C txog 2.75V. Lub peev xwm tiag tiag yog hais txog lub zog tiag tiag xa tawm raws li kev tso tawm tshwj xeeb, feem ntau cuam tshuam los ntawm kev tso tawm tus nqi thiab qhov kub thiab txias (yog li, nruj me ntsis hais lus, lub peev xwm roj teeb yuav tsum qhia txog cov nqi them / tso tawm). Cov roj teeb muaj peev xwm suav nrog Ah thiab mAh (1Ah=1000mAh).
IEC sawv cev rau dab tsi?
Lub IEC, lossis International Electrotechnical Commission, yog lub koom haum thoob ntiaj teb kev tsim qauv tsim los ntawm pawg kws tshaj lij hauv tebchaws. Nws lub hom phiaj yog los txhawb kev tsim qauv hauv kev lag luam hluav taws xob thiab hluav taws xob engineering thoob ntiaj teb. IEC cov qauv yog cov qauv tsim los ntawm International Electrotechnical Commission.
Dab tsi yog kev them nqi hluav taws xob?
Charging efficiency ntsuas qhov twg cov hluav taws xob siv hluav taws xob thaum lub sij hawm them roj teeb hloov mus rau hauv cov tshuaj siv hluav taws xob khaws cia hauv lub roj teeb. Nws yog feem ntau cuam tshuam los ntawm kev tsim cov roj teeb thiab kev ua haujlwm kub; Feem ntau, qhov kub ntawm ambient kub ua rau txo qis kev them nqi.
Dab tsi yog qhov tso tawm efficiency?
Kev siv hluav taws xob tawm yog qhov sib piv ntawm lub zog hluav taws xob tiag tiag tawm mus rau lub peev xwm ntsuas thaum tso tawm mus rau qhov kawg - ntawm - tawm hluav taws xob raws li cov xwm txheej. Nws yog feem ntau cuam tshuam los ntawm kev tso tawm tus nqi, ambient kub, thiab sab hauv tsis kam. Feem ntau, cov paug tawm ntau dua ua rau txo qis kev ua haujlwm, thiab qhov kub thiab txias kuj txo qis kev ua haujlwm tawm.
