Nrog rau kev thov nce ntxivnyob hauv hnub ci zog, ncov-kwv yees tus nqi hluav taws xob arbitrage, thiab lub zog thaub qab, ntau thiab ntau tsev neeg tab tom txhim kho cov khoom siv hluav taws xob hauv tsev. Txawm li cas los xij, ntau tus neeg siv tsuas yog tsom rau "ntau npaum li cas kilowatt-teev" thiab "ntau npaum li cas" thaum yuav cov roj teeb lub zog, tsis quav ntsej qhov tseem ceeb uas cuam tshuam rau cov neeg siv kev paub thiab kev ua neej.

 

Ib qho haumnyob hauv lub zog cia roj teebyuav tsum xav txog ntau yam kev ntsuas tshaj li qhov muaj peev xwm, suav nrog cov roj teeb hom, qhov hluav taws xob, lub zog, lub peev xwm tawm, lub neej voj voog, kev ua haujlwm nyab xeeb, thiab kev sib raug zoo. Cov kev txwv no ncaj qha txiav txim siab txog kev ruaj ntseg, kev lag luam, thiab kev nyab xeeb ntawm lub zog cia.

 

Raws li kev xaivcov qauv hauv cov khoom siv hluav taws xob hauv tsev cia khoomkev lag luam, muaj peev xwm, qhov tob ntawm qhov tso tawm (DoD), kev ua haujlwm zoo, lub neej voj voog, thiab kev sib txuas hluav taws xob yog txhua yam tseem ceeb uas cov neeg siv yuav tsum tau tsom mus rau.

 

 

 

Rated Peev Xwm (kWh) – Cov ntsiab lus ntawm Lub Zog Cia

 

1. Txhais:Tag nrho cov hluav taws xob ib lub roj teeb tuaj yeem khaws thaum them tag nrho, ntsuas hauv kWh (kilowatt-hours). Nws muaj ob lub ntsiab tseem ceeb: nominal peev thiab usable peev. Ntau tus neeg muag khoom tsuas yog sau lub peev xwm nominal, zais lub peev xwm siv tau.

 

2. Core Distinctions:

 

1). Nominal Peev Xwm:Theoretical tag nrho lub peev xwm ntawm cov roj teeb hlwb, xws li 10kWh, 15kWh, 20kWh;

 

2). Usable Capacity (Qhov muaj peev xwm tiag tiag tom qab DOD txwv):Lithium hlau phosphate roj teeb feem ntau muaj DOD ntawm 90% rau kev siv hauv tsev; Lub roj teeb 10kWh tsuas yog siv tau 9 kWh xwb. Ternary lithium roj teeb muaj qhov qis dua DOD, tsuas yog nyob ib ncig ntawm 80%.

 

3). Tsis txhob Pitfalls:Ua ntej nug txog lub peev xwm siv tau; tsis txhob cia li saib tus lej siab tshaj tawm. Rau kev siv hluav taws xob hauv tsev txhua hnub: xaiv 10-15kWh rau tsev neeg 2-4 siv hluav taws xob hmo ntuj; xaiv 20kWh lossis ntau dua rau off-grid backup fais fab thoob plaws hauv tsev.

 

 

Rated Fais fab / Nruam Them / Tawm Fais Fab (kW) - Instantaneous Load Capacity

 

1. Cov ntsiab lus: Chav kW sawv cev rau lub zog siab tshaj plaws uas lub roj teeb tuaj yeem ruaj khov tso zis / nqus tau, muab faib ua lub zog tawm mus tas li, lub zog siab tshaj plaws, thiab lub zog them.

 

1) Lub zog txuas ntxiv: Lub zog ruaj khov rau cov khoom siv hauv tsev nyob rau lub sijhawm ntev, txiav txim siab seb lub tshuab cua txias, lub tshuab rhaub dej, thiab lub tshuab hluav taws xob tuaj yeem qhib ib txhij;

 

2) Peak Fais Fab: luv-lub sij hawm (5-10 vib nas this) overload fais fab, pib lub tub yees, twj tso kua mis, thiab cua txias compressors;

 

2. Qhov tseem ceeb piv: Muaj peev xwm (kWh) ÷ Lub Hwj Chim (kW)=Lub Sijhawm Tawm. Kev lag luam categorizes roj teeb rau hauv siab - tus nqi, tus qauv- tus nqi, thiab qis- hom nqi:

 

1) 1C siab-Tus nqi: 10kWh / 10kW, 1 teev lub sijhawm tso tawm, haum rau siab -cov khoom siv hluav taws xob thiab tag nrho- tsev tawm - phiaj xwm ua haujlwm;

 

2) 0.5C Standard: 10kWh / 5kW, 2 teev tso tawm lub sijhawm, tus nqi -zoo rau kab sib chaws zoo tib yam- txuas hauv tsev siv;

 

3. Cov ntsiab lus zam: Qee cov phab ntsa- mounted me me lub zog cia chav tsev muaj lub zog tas mus li ntawm 3kW, uas yuav ncaj qha overload thiab kaw yog tias lub tshuab cua txias thiab induction cookers qhib ib txhij; rau siab- cov khoom siv fais fab, cov qauv nrog lub zog txuas ntxiv ntawm Ntau dua lossis sib npaug ntawm 8kW yuav tsum raug xaiv.

 

 

Qhov tob ntawm qhov tso tawm (DOD) - Kev txiav txim siab roj teeb lub neej

 

1. Lub ntsiab lus: Qhov tob ntawm qhov tso tawm (DOD) yog qhov feem pua ​​​​ntawm cov roj teeb lub peev xwm tuaj yeem tso tawm tag nrho. Nws yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau lub roj teeb lub neej.

 

2. Cell txawv:

 

1) Lithium Iron Phosphate (LFP): Mainstream rau hauv tsev cia, tso cai rau 90% DOD, lub neej voj voog ntev, nyab xeeb;

 

2) Ternary Lithium-Ion roj teeb (NCM): DOD tsuas yog 80%, lub zog siab ceev tab sis muaj kev pheej hmoo siab ntawm qhov kub thiab txias, tsis tshua siv hauv tsev siv;

3) Lead-acid roj teeb: DOD 50%, lub neej luv luv, maj mam raug txiav tawm.

 

3. Logic: Qhov siab dua qhov teeb tsa DOD, qhov ntau dua ntawm tes poob nrog txhua qhov tso tawm. Cov neeg tsim khoom yuav kaw qhov siab tshaj plaws DOD los ntawm Kev Tswj Xyuas Roj Teeb (BMS) los tiv thaiv lub roj teeb; cov khoom cuav uas sau nrog 100% DOD yuav muaj kev cuam tshuam ntawm tes sai heev.

 

Kev sib piv ntawm DOD rau cov roj teeb sib txawv

Cycle Life – Qhov taw qhia tseem ceeb rau tag nrho cov roj teeb lub neej

 

1. Cov ntsiab lus: Tus naj npawb ntawm kev them nqi- tso tawm mus ua tiav tom qab tus qauv DOD (Tshem tawm-Tawm) mus txog thaum lub roj teeb muaj peev xwm txo qis rau 80% yog lub hauv paus tseem ceeb rau kev tiv thaiv kev tiv thaiv.

 

2. Kev Lag Luam Standard Grading (Lithium Iron Phosphate rau Kev Siv Hauv Tsev):

 

1) Nkag mus -theem: 4000 cycles (6-8 xyoo ntawm kev siv);

 

2) Nruab nrab-ntau yam: 6000 cycles (10-12 xyoo siv);

 

3) High-kawg coj mus muag/kev lag luam qib hlwb: 8000-10000 cycles (tshaj 15 xyoo ntawm lub neej).

 

3. Conversion Formula: Ib qho kev them nqi tag nrho - tso tawm ib hnub, 6000 cycles ≈ 16 xyoo ntawm kev siv. Tsis suav nrog kev them nqi raws caij nyoog, lub neej tiag tiag rau kev siv hauv tsev yog tshaj 10 xyoo. Cov roj teeb uas muaj lub voj voog qis suav tau muaj peev xwm txo qis hauv 5 xyoos.

Thaum xaiv cov khoom siv hluav taws xob hauv tsev, ib qho yuav tsum tsis txhob xav txog "tus nqi" thiab "muaj peev xwm." Qhov tseeb txiav txim siab ntawm qhov ntev - lub sij hawm tus nqi yog tsim muaj peev xwm, sib piv lub zog, kev tiv thaiv kev nyab xeeb, lub neej voj voog, thiab kev sib raug zoo ntawm lub cev.

 

Rau cov neeg siv khoom siv hnub ci hluav taws xob hauv tsev, cov kev daws teeb meem tseem ceeb tam sim no feem ntau muaj xws li: Lithium hlau phosphate (LiFePO₄) hlwb + 48V / siab-voltage architecture + ntse BMS + tshaj 90% DoD + tshaj 6000 lub voj voog lub neej. Tsuas yog cov txheej txheem no tuaj yeem ua tiav kev siv hluav taws xob ntau dua, txo cov nqi hluav taws xob ntev dua -, thiab txhim khu kev ruaj ntseg hauv tsev ntau dua.
