Ob lub ntsiab lus tau dhau los ua neeg nyiam heev hauv kev siv lub zog cia: BMS (Battery Management System) thiab BESS (Battery Energy Storage System). Txawm tias muaj tseeb hais tias cov ntsiab lus no nquag siv synonymously, lawv xa mus rau txawv tab sis muaj feem xyuam nrog cov tswv yim. Nws yog ib qho tseem ceeb uas txhua tus neeg koom nrog hauv kev tsim, kev siv, lossis kev ua haujlwm ntawm lub zog cia kev daws teeb meem to taub qhov sib txawv ntawm BMS thiab BESS.
Battery Management System (BMS)
A Battery Management System (BMS)yog ib lub tshuab hluav taws xob uas saib xyuas, tswj, thiab ua kom zoo dua qhov kev ua tau zoo ntawm cov roj teeb uas siv tau los yog cov roj teeb ib leeg. Nws lub luag haujlwm tseem ceeb suav nrog:
1. Kev saib xyuas ntawm tes thiab kev tiv thaiv
Saib xyuas tus kheej ntawm tes voltages, kub, thiab tam sim no
Tiv thaiv overcharging, overdischarging, thiab thermal runaway
Ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm roj teeb
2. Xeev kwv yees
Xam Lub Xeev Tus Nqi (SoC) thiab Lub Xeev Kev Noj Qab Haus Huv (SoH)
Muab cov ntaub ntawv tseem ceeb rau kev tswj roj teeb
3. Sib npaug ntawm tes
Kev sib npaug ntawm cov nqi them thoob plaws ib lub hlwb
Maximizing lub peev xwm muaj thiab txuas ntxiv roj teeb lub neej
4. Thermal Management
Saib xyuas thiab tswj cov roj teeb kub
Ua kom pom kev ua haujlwm zoo rau lub pob roj teeb
Battery Energy Storage System (BESS)
A Battery Energy Storage System (BESS)yog ib qho kev ua tiav uas ua ke nrog ib lossis ntau lub pob roj teeb, nrog rau cov khoom siv hluav taws xob tsim nyog thiab kev tswj hwm, khaws cia thiab tso tawm hluav taws xob. BESS feem ntau muaj cov khoom nram qab no:
1. Roj teeb Modules lossis pob
Rechargeable roj teeb hlwb los yog modules teem nyob rau hauv series thiab parallel configurations
Lithium-ion, lead-acid, lossis lwm yam roj teeb thev naus laus zis
2. Roj Teeb Tswj System (BMS)
BMS, raws li tau piav qhia saum toj no, ua lub luag haujlwm tseem ceeb hauv kev tswj cov roj teeb pob
3. Fais fab Hloov System (PCS)
Inverters, converters, thiab txuam tswj systems
Ua kom muaj zog bi-directional ntws ntawm BESS thiab daim phiaj hluav taws xob lossis thauj khoom
4. Kev Tswj Xyuas Hluav Taws Xob (EMS)
Sophisticated software thiab tswj algorithms
Ua kom zoo rau kev ua haujlwm ntawm BESS raws li ntau yam (piv txwv li, tus nqi hluav taws xob, cov ntaub ntawv thauj khoom, kev tsim dua tshiab)
5. Cov Txheej Txheem Pabcuam
Cov tshuab cua txias, hluav taws kub tua hluav taws, thiab lwm yam kev txhawb nqa
Qhov txawv tseem ceeb ntawm BMS thiab BESS
Thaum BMS yog ib feem tseem ceeb ntawm BESS, ob nqe lus hais txog qhov sib txawv ntawm lub zog khaws cia:
A BMSyog ib qho kev mob siab rau tsom rau kev saib xyuas, tiv thaiv, thiab ua kom zoo rau kev ua haujlwm ntawm ib tus neeg lub roj teeb lossis pob khoom.
A BESSyog ib qho kev ua tiav uas suav nrog cov khoom siv roj teeb, BMS, cov khoom siv hluav taws xob hloov pauv, thiab cov kev tswj hwm tsim nyog rau lub zog cia thiab xa khoom.
Hauv cov ntsiab lus, BMS ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov pob roj teeb, thaum BESS yog qhov ua tiav lub zog khaws cia uas suav nrog cov roj teeb, hluav taws xob hluav taws xob, thiab cov tshuab tswj kom khaws thiab tso tawm hluav taws xob raws li qhov xav tau.
Kev siv ntawm BESS
Battery Energy Storage Systems (BESS) muaj ntau daim ntawv thov thoob plaws ntau qhov chaw
1. Kev sib koom ua ke zog tauj dua tshiab
Smoothing qhov sib cuam tshuam tso zis ntawm hnub ci thiab cua fais fab nroj tsuag
Txhim kho daim phiaj ruaj khov thiab kev ntseeg tau
2. Peak Shaving thiab Load Shifting
Txo qhov xav tau hluav taws xob siab tshaj plaws thiab cov nqi cuam tshuam
Kev khaws cia lub zog thaum lub sij hawm off-peak rau siv thaum lub sij hawm ncov xav tau
3. Kev Tswj Xyuas Zaus thiab Kev Pabcuam Ntxiv
Muab ceev ceev-teb zog reserves kom tswj kab sib chaws zaus
4. Thaub qab fais fab thiab Uninterruptible Power Supply (UPS)
Xyuas kom muaj hluav taws xob tsis tu ncua thaum muaj hluav taws xob lossis hluav taws xob cuam tshuam
5. Hluav taws xob tsheb (EV) Charging Infrastructure
Txhawb nqa ceev ceev chaw nres tsheb thiab tswj kev xav tau lub zog
6. Microgrids thiab Islanded Systems
Ua kom muaj kev sib koom ua ke ntawm kev faib khoom siv hluav taws xob
Txhim khu lub zog resilience thiab nws tus kheej txaus
Raws li qhov kev thov rau kev txhim khu kev qha, kev ruaj ntseg, thiab kev siv hluav taws xob zoo txuas ntxiv mus ntxiv, Roj Teeb Hluav Taws Xob Cia Hluav Taws Xob, kev txhawb nqa los ntawm Kev Tswj Xyuas Roj Teeb Siab Tshaj Plaws, yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub neej yav tom ntej ntawm lub zog hluav taws xob thoob ntiaj teb.
