Dab tsi yog qhov Charging Ratio ntawm Residential Energy Storage Battery?

 

 

 

 

Hauvnyob hauv lub zog cia systemsNtxiv rau qhov tsis muaj xws li roj teeb muaj peev xwm (kWh), roj teeb voltage (V), lub neej voj voog, thiab qhov tob ntawm qhov tso tawm (DoD), "them nqi" kuj yog qhov tseem ceeb ntawm kev ua haujlwm ntawm roj teeb.

 

Ntau tus neeg siv pom qhov tsis xws li 0.5C, 1C, thiab 2C them tus nqi thaum yuav khoomtsev zog cia roj teeb, tab sis tsis to taub qhov lawv txhais li cas. Yooj yim muab tso rau: Tus nqi them (C tus nqi) ntawm lub zog txuag hluav taws xob hauv tsev qhia tias lub roj teeb tau them hluav taws xob sai npaum li cas; Nws yog ib qho tseem ceeb rau kev ntsuas roj teeb lub peev xwm.

 

Piv txwv li:

 

● 1C them tus nqi: Theoretically, lub roj teeb tau them tag nrho hauv 1 teev;

 

● 0.5C them tus nqi: Txoj kev xav, lub roj teeb tau them tag nrho hauv 2 teev;

 

● 2C them tus nqi: Raws li kev xav, lub roj teeb tau them tag nrho hauv 30 feeb.

 

Raunyob hauv hnub ci + lub zog cia tshuab, xaiv tus nqi them tus nqi zoo tuaj yeem txhim kho kev siv hluav taws xob hnub ci, txo cov nqi hluav taws xob, thiab txuas ntxiv roj teeb lub neej.

 

 

 

 

Dab tsi yog tus nqi them ntawm lub zog hluav taws xob hauv tsev cia khoom?

 

Tus nqi them, feem ntau yog qhia raws li C- tus nqi, piav qhia qhov piv ntawm lub roj teeb them tam sim no thiab lub roj teeb lub peev xwm ntsuas.

 

Kev suav cov mis:

 

Tus nqi them (C)=Them tam sim no (A) ÷ Roj teeb muaj peev xwm (Ah)

 

Piv txwv:

 

Ib lub roj teeb:

 

● Roj teeb muaj peev xwm: 100Ah

 

● Them tam sim no: 50A

 

Tom qab ntawd: 50A ÷ 100Ah=0.5C

 

Qhov no txhais tau hais tias lub roj teeb tau them ntawm 0.5C tus nqi.

 

Piv txwv:

 

Roj teeb muaj peev xwm	Kev them nqi tam sim no	Tus nqi them	Kev tshawb xav yog puv sijhawm
10 kWh	50A	0.5C	Kwv yees li 2 teev
10 kWh	100A	1C	Kwv yees li 1 teev
10 kWh	200A	2C	Kwv yees li 30 feeb
20 kWh	100A	0.5C	Kwv yees li 2 teev

 

 

Dab tsi yog kev sib raug zoo ntawm kev them nqi thiab roj teeb muaj peev xwm?

 

Ntau tus neeg siv khoom yooj yim tsis meej pem:

 

● kWh (muaj peev xwm) txiav txim siab npaum li cas hluav taws xob khaws cia

 

● Tus nqi them (C- tus nqi) txiav txim siab them ceev

 

Cov no yog cov ntsuas sib txawv.

 

Piv txwv li: A 16kWh nyob hauv lub zog cia roj teeb:

 

Yog tias:

 

● 0.5C them → Ntau tshaj them lub zog kwv yees li 8kW

 

● 1C kev them nyiaj → Lub zog them siab tshaj plaws kwv yees li 16kW

 

Hauv lwm lo lus, rau tib lub peev xwm roj teeb, cov nqi them sib txawv yuav cuam tshuam rau lub hnub ci zog nws tuaj yeem nqus tau ntau npaum li cas txhua hnub.
