GMCELL 1.5V 3000mWh USB AA AAA Roj Teeb Hom-C Rechargeable Lithium ion USB Roj Teeb

1. Lub neej ntev voj voog

A-qib 14500 lithium cell: Siv cov roj teeb lithium-ion zoo 14500-spec (sib npaug rau AA loj), ua kom muaj kev ua haujlwm ruaj khov los ntawm kev tswj hwm zoo, sib xws nrog ntau yam khoom siv roj teeb AA.
Lub neej siv tau 1000 lub voj voog: Txhawb nqa txog li 1000 lub voj voog them-tso tawm, khaws cia ≥80% lub peev xwm tom qab 3 xyoos siv *, ntau dua li cov roj teeb nickel-hlau hydride ib txwm (≈500 lub voj voog) thiab cov roj teeb pov tseg, nrog rau cov nqi siv mus sij hawm ntev qis dua.
*Ceeb Toom: Lub neej voj voog raws li cov xwm txheej sim txheem (0.5C them-tso tawm, 25°C ib puag ncig).

2. Cov thev naus laus zis hluav taws xob tas mus li, kev sib raug zoo ntawm cov khoom siv muaj zog

1.5V qhov hluav taws xob tas li: Lub rooj tsavxwm PCB uas muaj qhov sib npaug tam sim no ua rau lub zog hluav taws xob tso tawm tiag tiag, tswj tau qhov hluav taws xob 1.5V ruaj khov thoob plaws. Hloov tau zoo kawg nkaus rau cov roj teeb qhuav 1.5V ib txwm muaj (piv txwv li, cov roj teeb alkaline AA/AAA), daws qhov teeb meem hluav taws xob poob qis ntawm cov roj teeb lithium ib txwm muaj (uas maj mam tso tawm ntawm 4.2V mus rau 3.0V).Kev sib xws ntawm cov khoom siv dav dav: Ua haujlwm nrog 1.5V-powered smart home devices (smart locks, robot vacuums), cov khoom siv hluav taws xob (wireless nas, keyboards, gamepads), thiab cov cuab yeej sab nraum zoov (headlamps, flashlights), thiab lwm yam, tsis tas yuav hloov kho cov khoom siv rau kev hloov pauv ncaj qha.

3. Lub zog ceev ceev, lub zog ntev

3300mWh muaj peev xwm loj: Ib lub cell muab 3300mWh lub zog ceev (≈850mAh/3.7V), nce 65% piv rau tib lub roj teeb alkaline loj (≈2000mWh) thiab 83% piv rau cov roj teeb nickel-hlau hydride ib txwm (≈1800mWh). Ib zaug them txhawb kev ua haujlwm ntev dua ntawm lub cuab yeej (piv txwv li, lub roj teeb nas wireless txuas ntxiv los ntawm 1 lub hlis mus rau 3 lub hlis).

Kev tso zis hluav taws xob siab: Kev tsim qauv tsis tshua muaj zog sab hauv (22mΩ-45mΩ) txhawb nqa kev tso tawm tam sim ntawd, tsim rau cov khoom siv hluav taws xob siab (piv txwv li, teeb nyem, cov khoom ua si hluav taws xob), zam "kev tsis txaus hluav taws xob" los ntawm kev tiv thaiv sab hauv siab hauv cov roj teeb ib txwm muaj.

4. Tsim qauv qis dua tus kheej, khaws cia tsis txhawj xeeb thiab thaub qab

Kev khaws cia ntev heev: Siv cov thev naus laus zis uas tso tawm tus kheej tsawg, poob ≤5% ntawm tus nqi tom qab 1 xyoos ntawm kev khaws cia ntawm 25 ° C, zoo dua li cov roj teeb nickel-hlau hydride ib txwm muaj (≈30% tus nqi tso tawm tus kheej / xyoo). Zoo tagnrho rau cov xwm txheej thaub qab mus sij hawm ntev (piv txwv li, teeb ci thaum muaj xwm txheej ceev, roj teeb tswj chaw taws teeb).

Npaj siv tau: Tsis tas yuav rov them dua ntau zaus; siv tam sim ntawd tom qab tshem tawm, txo qhov txaj muag ntawm "roj teeb tuag". Tshwj xeeb tshaj yog haum rau cov khoom siv uas tsis tshua siv tab sis npaj txhij txhua lub sijhawm (piv txwv li, lub tswb ceeb toom pa luam yeeb, lub qhov rooj xauv hluav taws xob).

5. USB-C them ceev ceev, kev them nqi hluav taws xob tshiab

Hom-C chaw nres nkoj them ncaj qha: Lub chaw nres nkoj them USB-C uas ua rau hauv tsis tas yuav muaj cov chaw them ntxiv lossis cov chaw nres nkoj. Them ncaj qha los ntawm USB-C chaw nres nkoj ntawm cov xov tooj ntawm tes them, laptops, lub txhab nyiaj fais fab, thiab lwm yam, hais lus zoo rau qhov teeb meem ntawm kev nrhiav cov chaw them tshwj xeeb rau cov roj teeb ib txwm muaj.

Kev them ceev 5V 1A-3A: Sib xws nrog cov zis dav dav (1A-3A), them tau 80% hauv 1 teev (hom them ceev 3A) thiab them tag nrho hauv 2 teev—3 zaug sai dua li cov roj teeb nickel-hlau hydride ib txwm (them qeeb 4-6 teev).
Kev tsim qauv sib xws rov qab: Txhawb nqa 5V input voltage, siv tau nrog cov chargers qub 5V / 1A kom tsis txhob muaj teeb meem sib xws ntawm cov khoom siv.

VI. Kev lav ob npaug ntawm kev nyab xeeb thiab kev tiv thaiv ib puag ncig

Kev tiv thaiv ntau lub voj voog: Cov chips tiv thaiv overvoltage, overcurrent, thiab overheat uas ua rau hauv lub roj teeb yuav txiav tawm lub zog thaum lub sijhawm them kom tiv thaiv kev o lossis kev pheej hmoo ntawm hluav taws. Tau ntawv pov thawj los ntawm cov qauv thoob ntiaj teb xws li UN38.3 thiab RoHS rau kev siv nyab xeeb dua.

Kev ruaj khov ntsuab: Kev tsim qauv uas rov them tau dua hloov cov roj teeb pov tseg - ib lub cell txuag tau ≈1000 roj teeb alkaline, txo cov pa phem hlau hnyav thiab ua raws li EU Battery Regulation ib puag ncig cov cai.
