1. Dab tsi yog qhov zoo tshaj plaws tam sim no rau rechargeable lithium roj teeb?

Cov roj teeb lithium yuav tsum tau them nrog qhov tam sim no ua ntej, uas yog, yuav tsum muaj tam sim no, thiab cov roj teeb hluav taws xob thiab cov txheej txheem them nyiaj maj mam nce, thaum lub roj teeb voltage yog 4.2V, nws yuav tsum ncav cuag 4.1V), rau qhov kev them nyiaj tas li, tsis yog lub roj teeb. voltage yuav tsum muaj lub hauv paus ntawm tam sim no Full-scale tas li them tam sim no yog ua nyob rau sab sauv, thiab cov txheej txheem them nqi txuas ntxiv txo. Thaum qhov kub thiab txias qis rau 0.01 degrees Celsius, lub charger nres. (C yog ib txoj kev qhia txog lub peev xwm ntawm lub roj teeb raws li qhov tam sim no. Piv txwv li, yog tias lub roj teeb muaj peev xwm yog 1000mAh, 1C yog qhov them tam sim no ntawm 1000mA. Nco ntsoov tias qhov no yog mA, tsis yog Ah. Vim li cas xav tias 0.01C. yog tus nqi davhlau ya nyob twg: Qhov no yog lub teb chaws tus qauv GB / T18287-2000 kuj yog kev tshuaj xyuas yav dhau los, peb tau ua tiav 20mA. Cov qauv kev lag luam YD / T998-1999 ntawm Ministry of Posts thiab Telecommunications muaj tib txoj cai, uas yog, txawm li cas los xij lub roj teeb muaj peev xwm loj npaum li cas, qhov nres tam sim no yog 20mA. Lub teb chaws tus qauv 0.01c muaj txiaj ntsig zoo rau kev them nyiaj ntau dua, qhov no yog qhov txiaj ntsig tau lees paub los ntawm cov chaw tsim khoom. Tsis tas li ntawd, lub teb chaws tus qauv qhia tias lub sijhawm them nyiaj yuav tsum. tsis tshaj 8 teev, uas yog, txawm tias nws tsis ncav cuag 0.01c, nws yog suav hais tias yog 8 teev them. (Lub roj teeb zoo tsis muaj teeb meem, thiab nws yuav tsum nyob rau hauv 8 teev. lub roj teeb zoo, thiab nws tsis muaj nuj nqis tos) Qhov zoo tshaj plaws ch arging tus nqi ntawm lithium ion los yog lithium yog 0.01 c, uas txhais tau hais tias ib tug 1 mAh roj teeb muaj ib tug ceev them tam sim no ntawm 1000 mAh thiab tus nqi yog qhov no Qhov ceev tuaj yeem ua kom tiav cov kev them nyiaj hauv lub sijhawm luv tshaj yam tsis tau txo cov roj teeb kev ua haujlwm thiab txo qhov kev pabcuam. lub neej. Yuav kom ua tiav qhov txaus siab them tus nqi no, nws yog ib qho tsim nyog yuav tsum tau ua kom cov nqi them tam sim no ntawm lub roj teeb pob raws li lub peev xwm nce.

2. Dab tsi yog qhov zoo tshaj plaws voltage rau rechargeable lithium roj teeb?

Lub nominal voltage ntawm lithium roj teeb yog 3.7V (3.6V), thiab tus nqi txiav tawm voltage yog 4.2V (4.1V, nyob ntawm seb lub roj teeb hom, thiab tus tsim yog txawv). Yuav ua li cas paub qhov txawv ntawm 4.1V thiab 4.2V: Cov neeg siv khoom tsis tuaj yeem paub qhov txawv ntawm nws, thiab nws nyob ntawm lub roj teeb tsim Chaw tsim khoom cov khoom specifications. Qee hom roj teeb feem ntau yog 4.1V thiab 4.2V, xws li A&TB (Toshiba), cov tuam txhab tsim khoom hauv tsev yog 4.2V. Yuav ua li cas yog tias koj them lub roj teeb 4.1V rau 4.2V? Qhov no yuav ua rau kom lub roj teeb muaj peev xwm thiab ua kom yooj yim rau kev siv. Piv txwv li los ntawm 500 mus rau 300. Ib yam li ntawd, yog hais tias lub 4.2V roj teeb yog overcharged, nws lub neej yuav luv luv. Cov roj teeb lithium tsis muaj zog. Yog tias lub roj teeb muaj lub rooj tiv thaiv, peb puas tuaj yeem kho nws? Tsis yog, vim tias qhov kev txiav tawm ntawm lub rooj tiv thaiv kev tiv thaiv yog 4.35V (ok, tab sis qhov sib txawv ntawm 4.4V thiab 4.5V), yog li lub rooj tiv thaiv kev tiv thaiv yuav tsum cuam tshuam nrog qhov nruab nrab zaus. Yog tias lub roj teeb tau them txhua zaus, nws yuav muaj hnub nyoog sai.

3. Lub roj teeb muaj peev xwm ntawm Apple iPhone yog dab tsi?

Kua iPhone roj teeb specifications muaj ib tug nominal voltage ntawm 3.7V, ib tug them-off voltage ntawm 4.2V, thiab lub roj teeb muaj peev xwm ntawm 1400mAh. Nws tuaj yeem pom los ntawm cov saum toj no tias qhov zoo tshaj plaws them tus nqi yog 1C. Qhov tam sim no xav tau kom ncav cuag 1400mA pib them ntawm qhov hluav taws xob ntawm 3.7V.

4. Dab tsi yog qhov voltage thiab tam sim no ntawm usb chaw nres nkoj thiab charger?

Usb interface tam sim no yog 500mA, voltage yog +5V. Yog tias koj tig HWinfo thaum them nyiaj, koj tuaj yeem pom cov khoom siv hluav taws xob sab nraud. Lub 500mA charger yog tsim rau iPhone. Hauv cov ntsiab lus, thaum USB them nyiaj, qhov hluav taws xob yog + 5V thiab tam sim no tsuas yog 500mA. Los ntawm cov lus teb rau nqe lus nug 1 thiab nqe lus nug 2, peb paub tias txoj kev no ua kom lub roj teeb muaj peev xwm, uas yog txias rau siv, tab sis txo cov roj teeb lub neej. Thaum siv lub charger los them, peb yuav nug, tsis yog koj hais tias qhov ceev tshaj plaws yog 1C? Nws yog qhov tseeb uas xav tias iPhone yuav tsum tau them nrog tam sim no ntawm 1400mA, yog, tab sis lub teb chaws kuj muaj cov cai. Tus nqi them qis uas tau teev tseg los ntawm gb yog 0.2C. (Regulated charging system), kuj coj iPhone lub peev xwm 1400mAh roj teeb ua piv txwv, uas yog 280mA. Hauv txoj kev xav, lub roj teeb me dua, qhov txiaj ntsig zoo dua. Tab sis koj tsis tuaj yeem tos peb hnub rau kev them roj teeb. (Lub peev xwm mAh = tam sim no mA x lub sijhawm h) Yog li Apple xaiv 0.7C, feem ntau cov roj teeb nyob nruab nrab ntawm 0.5C thiab 0.8C, koj tuaj yeem xaiv 5! Pom tseeb, qee tus neeg siv USB los them, uas xav tias lub neej ntev dua, tab sis qhov no yog lub roj teeb tshwj xeeb Tus nqi ntawm lub neej
