Raws li cov khoom siv hluav taws xob tau dhau los ua lub zog tshaib plab thiab cov thev naus laus zis ceev tau hloov zuj zus, ntau tus neeg siv khoom xav tsis thoob:Puas yog cov khoom siv hluav taws xob ntau dua siv hluav taws xob ntau dua?Cov lus teb suav nrog kev nkag siab txog kev siv hluav taws xob, kev them nqi hluav taws xob, thiab kev them nyiaj niaj hnub ua haujlwm li cas. Phau ntawv qhia tob no tshuaj xyuas kev sib raug zoo ntawm lub charger wattage thiab kev siv hluav taws xob.
Nkag siab txog Charger Wattage Fundamentals
Wattage txhais li cas hauv Chargers?
Wattage (W) sawv cev rau lub zog siab tshaj plaws uas lub charger tuaj yeem xa tau, suav nrog: Watts (W) = Volts (V) × Amps (A)
- Standard xov tooj chargerLub hwj chim: 5W (5V × 1A)
- Fast smartphone charger18-30W (9V × 2A lossis siab dua)
- Laptop chargerLub hwj chim: 45-100W
- EV ceev chargerLub hwj chim: 50-350 kW
The Charging Power Curve Myth
Raws li kev ntseeg nrov, chargers tsis tas li ua haujlwm ntawm lawv cov wattage siab tshaj plaws. Lawv ua raws li cov txheej txheem xa hluav taws xob dynamic uas hloov kho raws li:
- Ntaus lub roj teeb theem (ceev them ceev tshwm sim feem ntau ntawm qis feem pua)
- Roj teeb kub
- Cov cuab yeej tswj fais fab muaj peev xwm
Puas Cov Hluav Taws Xob Hluav Taws Xob puas siv hluav taws xob ntau dua?
Lus Teb luv luv
Tsis tas li.Lub charger siab dua tsuas yog siv hluav taws xob ntau dua yog tias:
- Koj lub cuab yeej tuaj yeem lees txais thiab siv lub zog ntxiv
- Cov txheej txheem them nqi tseem ua haujlwm ntev dua li qhov tsim nyog
Yam tseem ceeb cuam tshuam txog kev siv hluav taws xob tiag tiag
- Device Power Negotiation
- Cov khoom siv niaj hnub no (xov tooj, laptops) sib txuas lus nrog cov chargers kom thov tsuas yog lub zog lawv xav tau
- Ib qho iPhone ntsaws rau hauv 96W MacBook charger yuav tsis rub 96W tshwj tsis yog tsim los
- Charge Efficiency
- Cov khoom siv hluav taws xob zoo dua feem ntau muaj kev ua haujlwm zoo dua (90% + vs. 60-70% rau cov nqi pheej yig)
- Cov khoom siv hluav taws xob ntau dua siv hluav taws xob tsawg dua li cua sov
- Them sij hawm
- Cov chargers ceev ceev tuaj yeem ua kom them sai dua, muaj peev xwm txo tau tag nrho kev siv zog
- Piv txwv li: Lub charger 30W tuaj yeem sau lub xov tooj roj teeb hauv 1 teev vs 2.5 teev rau 10W charger
Cov piv txwv ntawm kev siv hluav taws xob hauv ntiaj teb tiag
Smartphone Charging Sib piv
| Charger Wattage | Fais fab Draw tiag tiag | Them sij hawm | Tag Nrho Zog Siv |
|---|---|---|---|
| 5W (tus qauv) | 4.5W (avg) | 3 hnu | 13.5 wb |
| 18W (ceev) | 16W (siab tshaj) | 1,5h ib | 14 Wh* |
| 30W (yeem) | 25W (siab tshaj) | 1 hnu | 15 Wh* |
* Ceeb Toom: Cov chargers ceev ceev siv sij hawm tsawg dua nyob rau hauv high-power hom li roj teeb puv
Laptop Charging Scenario
Lub MacBook Pro tuaj yeem kos:
- 87W los ntawm 96W charger thaum siv hnyav
- 30-40W thaum siv lub teeb
- <5W thaum them tag nrho tab sis tseem ntsaws
Thaum muaj hluav taws xob ntau dua li siv hluav taws xob
- Cov khoom qub / Tsis-Smart Devices
- Cov khoom siv uas tsis muaj kev sib tham nrog lub zog tuaj yeem rub lub zog muaj zog tshaj plaws
- Kev siv hluav taws xob tsis tu ncua
- Gaming laptops khiav ntawm kev ua haujlwm puv sijhawm thaum them nyiaj
- EVs siv DC chaw them ceev ceev
- Cov Khoom Siv Tsis Zoo / Tsis Ua Raws Cai
- Tej zaum yuav tsis zoo tswj kev xa hluav taws xob
Kev txiav txim siab txog kev siv hluav taws xob
- Kev siv hluav taws xob Standby
- Chargers zoo: <0.1W thaum tsis them
- Cov chargers tsis zoo: tuaj yeem kos 0.5W lossis ntau dua txuas ntxiv
- Kev them nyiaj kub poob
- Kev them nyiaj ntau dua ua rau muaj cua sov ntau dua, sawv cev rau lub zog pov tseg
- Cov chargers zoo txo qhov no los ntawm kev tsim kom zoo dua
- Lub roj teeb Health Impact
- Kev them nyiaj sai sai yuav txo qis me ntsis roj teeb lub sijhawm ntev
- Qhov no ua rau muaj kev them nyiaj ntau dua thaum lub sijhawm
Cov lus pom zoo
- Txuas Charger rau Device Xav tau
- Siv cov chaw tsim khoom-pom zoo wattage
- Ntau dua wattage muaj kev nyab xeeb tab sis tsuas yog muaj txiaj ntsig yog tias koj lub cuab yeej txhawb nqa nws
- Unplug Chargers thaum tsis siv
- Tshem tawm standby fais fab tuag
- Kev nqis peev hauv Quality Chargers
- Nrhiav 80 Ntxiv lossis cov ntawv pov thawj zoo sib xws
- Rau cov roj teeb loj (EVs):
- Theem 1 (120V) them nyiaj ntau tshaj rau cov kev xav tau niaj hnub
- Khaws lub zog siab DC ceev them rau kev mus ncig thaum xav tau
Kab hauv qab
Siab dua wattage chargersua tausiv hluav taws xob ntau dua thaum nquag them ntawm lawv lub peev xwm, tab sis cov tshuab them nyiaj niaj hnub no tau tsim los tsuas yog kos lub zog xav tau los ntawm lub cuab yeej. Feem ntau, kev them nyiaj sai tuaj yeem txo tag nrho lub zog siv los ntawm kev ua kom tiav lub voj voog kom sai dua. Cov yam tseem ceeb yog:
- Koj lub cuab yeej tswj fais fab muaj peev xwm
- Charger zoo thiab efficiency
- Koj siv lub charger li cas
Los ntawm kev nkag siab txog cov ntsiab cai no, cov neeg siv khoom tuaj yeem txiav txim siab paub txog lawv cov khoom siv them nyiaj yam tsis muaj kev txhawj xeeb txog hluav taws xob pov tseg. Raws li kev them nyiaj thev naus laus zis txuas ntxiv mus, peb tab tom pom ntau dua wattage chargers uas tuav lub zog ua haujlwm zoo los ntawm cov khoom siv hluav taws xob ntse.
