Cov roj teeb yog qhov tseem ceeb rau kev siv ntau yam khoom siv niaj hnub no, los ntawm smartphones mus rau lub tsheb fais fab. Ib qho tseem ceeb ntawm cov roj teeb kev ua tau zoo yog C-rating, uas qhia txog tus nqi them thiab tso tawm. Phau ntawv qhia no piav qhia tias lub roj teeb C-kev ntsuas yog dab tsi, nws qhov tseem ceeb, yuav suav li cas, thiab nws cov ntawv thov.
Lub roj teeb C-Rating yog dab tsi?
Lub roj teeb C-kev ntsuas yog ntsuas ntawm tus nqi uas nws tuaj yeem raug them lossis tso tawm cuam tshuam rau nws lub peev xwm. Lub peev xwm ntawm lub roj teeb feem ntau yog ntsuas ntawm 1C tus nqi. Piv txwv li, lub roj teeb tag nrho 10Ah (ampere-teev) ntawm 1C tus nqi tuaj yeem xa 10 amps ntawm tam sim no rau ib teev. Yog tias tib lub roj teeb tawm ntawm 0.5C, nws yuav muab 5 amps tshaj li ob teev. Hloov pauv, ntawm 2C tus nqi, nws yuav xa 20 amps rau 30 feeb. Kev nkag siab txog C-kev ntsuam xyuas pab rau kev ntsuam xyuas sai npaum li cas lub roj teeb tuaj yeem muab lub zog tsis muaj kev ua haujlwm tsis zoo.

Daim ntawv qhia hauv qab no qhia txog qhov sib txawv C-kev ntsuas thiab lawv cov sijhawm ua haujlwm sib raug. Txawm hais tias kev suav cov theoretical qhia tias cov khoom siv hluav taws xob yuav tsum nyob twj ywm thoob plaws C-tus nqi sib txawv, qhov xwm txheej tiag tiag hauv ntiaj teb feem ntau cuam tshuam nrog lub zog poob. Ntawm C-tus nqi siab dua, qee lub zog poob raws li cov cua sov, uas tuaj yeem txo cov roj teeb lub peev xwm los ntawm 5% lossis ntau dua.

| C-Rating | Lub Sijhawm Kev Pabcuam (Time) |
|---|---|
| 30 C | 2 feeb |
| 20 C | 3 feeb |
| 10 C | 6 feeb |
| 5C | 12 feeb |
| 2C | 30 feeb |
| 1C | 1 teev |
| 0.5C los yog C / 2 | 2 teev |
| 0.2C los yog C / 5 | 5 hnu |
| 0.1C los yog C / 10 | 10 teev |
Yuav ua li cas xam tus C ntsuas ntawm lub roj teeb
C-kev ntsuam xyuas ntawm lub roj teeb yog txiav txim siab los ntawm lub sijhawm nws yuav siv los them lossis tso tawm. Los ntawm kev kho tus nqi C, lub sijhawm them lossis tawm ntawm lub roj teeb raug cuam tshuam raws li. Cov mis rau xam lub sij hawm (t) yog ncaj nraim:
- Nyob rau hauv lub sij hawm:t = 1 / Cr (saib hauv teev)
- Rau lub sijhawm hauv feeb:t = 60 / Cr (saib hauv feeb)
Piv txwv suav:
- 0.5C tus nqi piv txwv:Rau lub roj teeb 2300mAh, qhov muaj tam sim no suav nrog hauv qab no:
- Peev xwm: 2300mAh / 1000 = 2.3Ah
- Tam sim no: 0.5C x 2.3Ah = 1.15A
- Sijhawm: 1 / 0.5C = 2 teev
- 1C tus nqi piv txwv:Ib yam li ntawd, rau 2300mAh roj teeb:
- Peev xwm: 2300mAh / 1000 = 2.3Ah
- Tam sim no: 1C x 2.3Ah = 2.3A
- Sijhawm: 1 / 1C = 1 teev
- 2C tus nqi piv txwv:Ib yam li ntawd, rau 2300mAh roj teeb:
- Peev xwm: 2300mAh / 1000 = 2.3Ah
- Tam sim no: 2C x 2.3Ah = 4.6A
- Sijhawm: 1 / 2C = 0.5 teev
- 30C tus nqi piv txwv:Rau 2300mAh roj teeb:
- Peev xwm: 2300mAh / 1000 = 2.3Ah
- Tam sim no: 30C x 2.3Ah = 69A
- Sijhawm: 60 / 30C = 2 feeb
Yuav Ua Li Cas Nrhiav C ntsuas ntawm lub roj teeb
C-kev ntsuam xyuas ntawm lub roj teeb feem ntau yog teev nyob rau hauv nws daim ntawv lo lossis cov ntaub ntawv. Cov roj teeb me me feem ntau ntsuas ntawm 1C, tseem hu ua tus nqi ib teev. Cov chemistry sib txawv thiab cov qauv tsim ua rau sib txawv C-tus nqi. Piv txwv li, cov roj teeb lithium feem ntau txhawb kev tso tawm ntau dua piv rau cov roj lead-acid lossis alkaline roj teeb. Yog tias qhov C-rating tsis tau yooj yim, sab laj nrog cov chaw tsim khoom lossis xa mus rau cov ntaub ntawv ntxaws txog cov khoom lag luam.
Cov ntawv thov yuav tsum muaj tus nqi siab C
High C-rate roj teeb yog qhov tseem ceeb rau cov ntawv thov uas xav tau kev xa hluav taws xob sai. Cov no suav nrog:
- RC Qauv:Tus nqi tso tawm siab muab qhov tawg ntawm lub zog xav tau rau kev nrawm nrawm thiab maneuverability.
- Drones:Kev siv hluav taws xob zoo tawg ua rau lub sijhawm ya davhlau ntev dua thiab txhim kho kev ua haujlwm.
- Robotics:High C-tus nqi txhawb lub zog dynamic xav tau ntawm robotic txav thiab ua haujlwm.
- Tsheb Jump Starters:Cov khoom siv no xav tau lub zog tseem ceeb tawg kom pib lub cav sai sai.
Hauv cov ntawv thov no, xaiv lub roj teeb uas tsim nyog C-kev ntsuam xyuas kom ntseeg tau thiab ua haujlwm zoo.
