Cov tshuab hluav taws xob hauv kev lag luam xa mus rau qhov loj - cov khoom siv hluav taws xob txuag hluav taws xob siv hauv cov khoom lag luam. Lawv tsom los txhim kho kev siv hluav taws xob zoo, sib npaug ntawm daim phiaj xwm txheej, hais txog qhov sib cuam tshuam ntawm cov khoom siv hluav taws xob tauj dua tshiab, thiab muab kev txhawb zog thaum muaj xwm txheej ceev. Rau cov khoom uas tau hais los saum toj no, thov nias hauv qab no kom paub ntau ntxiv txog lawv cov specifications.
Lub kaw lus no feem ntau muaj cov roj teeb cia lub zog (xws li lithium{0}}ion thiab lithium hlau phosphate roj teeb), lub roj teeb tswj kev tswj hwm (BMS), lub zog hloov hluav taws xob (PCS), qhov ntsuas kub, thiab lub tshuab saib xyuas. Nws nta kev them nqi / tso tawm, kev tiv thaiv kev nyab xeeb, thiab kev saib xyuas cov ntaub ntawv. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv kev ua tiav qhov siab tshaj plaws shaving thiab valley filling, thov cov lus teb, microgrid stability, thiab lub zog thaub qab, ua rau nws tsim nyog rau cov chaw tsim khoom, cov chaw zov me nyuam, thiab cov chaw tsim hluav taws xob tshiab.
Nyob rau hauv cov nqe lus ntawm cov qauv kev, muaj zog cia tshuab siv bidirectional converters los hloov AC rau DC zog. Lub roj teeb ntim tau them thaum lub sijhawm tawm - cov sij hawm siab tshaj thiab tawm thaum lub sij hawm siab tshaj, txo cov nqi hluav taws xob. BMS yog lub luag haujlwm rau kev ntsuas ntawm tes, kev tiv thaiv overvoltage / undervoltage, thiab ntsuas kub kom ntseeg tau tias muaj kev nyab xeeb. Noj lithium- roj teeb lithium ua piv txwv, lawv muaj lub zog ceev (feem ntau 150-250Wh / kg) thiab lub neej ntev (3000-5000 cycles @ 80% muaj peev xwm), tab sis xav tau kev tswj xyuas nruj ntawm thermal runaway pheej hmoo. Lithium hlau phosphate (LFP) roj teeb muaj peev xwm tiv taus qhov kub thiab txias thiab muaj lub neej ntev dua (4000-7000 cycles), tab sis lawv lub zog ntom ntom me ntsis.
Cov xwm txheej ntawm daim ntawv thov suav nrog: 1. Kev tswj hwm lub zog zaus (teb teb ceev yuav tsum nyob rau qib millisecond); 2. Kev them nyiaj yug photovoltaic / cua zog (kho kom dhau lub zog tsim hluav taws xob thiab ua kom zoo nkauj); 3. Muaj chaw ua si (yuav tsum tau 1-4 teev ntawm lub zog cia khoom tsim raws li kev thauj khoom nkhaus); 4. Thaum muaj xwm ceev fais fab mov (hloov sij hawm<20ms). Industry standards such as IEC 62933 and UL 9540 have strict requirements for safety and performance. During installation, fireproof distance (recommended ≥1m), ventilation (air exchange rate ≥5 times/hour), and seismic resistance requirements (8-level seismic design) must be considered.
Kev ceev faj: 1. Cell kub sib txawv yuav tsum tau tswj nyob rau hauv ± 2℃kom ntev lifespan; 2. Ua lub peev xwm ntsuas tsis tu ncua (pom zoo txhua 6 lub hlis); 3. Tsis txhob ncua sij hawm tag nrho - nqi cia (SOC pom zoo kom khaws cia ntawm 30-70%); 4. Derating yuav tsum tau nyob rau hauv high-altitude cheeb tsam (muaj peev xwm txo los ntawm kwv yees li 3% rau txhua txhua 1000m nce nyob rau hauv qhov siab). Cov cuab yeej txhawb nqa yuav tsum muaj xws li hluav taws kub tua hluav taws (heptafluoropropane lossis perfluorohexanone gas fire extinguishing) thiab cov cuab yeej ntsuas hluav taws xob (nrhiav cov dej xau tam sim no<10mA).
