Lub zog cia lub zog feem ntau suav nrog lub roj teeb, lub roj teeb tswj kev tswj hwm (BMS), lub zog tsim hluav taws xob (PCS), kev tswj hwm hluav taws xob (EMS), thiab cov cuab yeej pabcuam xws li kev tswj xyuas thermal thiab kev tiv thaiv hluav taws.
Cov khoom no ua haujlwm ua ke kom ua tiav qhov kev cia, hloov dua siab tshiab, teem sijhawm, thiab kev nyab xeeb ntawm cov hluav taws xob hluav taws xob, thiab tau siv dav hauv kev ua haujlwm siab tshaj plaws, kev tswj hwm zaus thiab qhov hluav taws xob, thiab cov khoom siv hluav taws xob thaub qab ntawm cov tiam, kab sib chaws, thiab cov neeg siv sab.
1. Roj teeb System (Core Energy Carrier)
Lub roj teeb system yog "lub plawv" ntawm lub zog cia, lub luag haujlwm rau kev khaws cia thiab tso tawm ntawm hluav taws xob hluav taws xob. Nws feem ntau siv cov roj teeb lithium hlau phosphate thiab tau muab faib ua ntau theem:
Cell → Module → Battery Cluster → Battery Stack. Ntau lub roj teeb sib txuas sib txuas ua ke tuaj yeem ua tiav megawatt- qib kev cia khoom muaj peev xwm.
2. Roj Teeb Tswj System (BMS, "Tus Saib Xyuas" ntawm lub roj teeb)
BMS saib xyuas cov roj teeb tsis zoo xws li voltage, tam sim no, kub, thiab SOC (State of Charge) hauv lub sijhawm tiag tiag los tiv thaiv overcharging, tshaj - tso tawm, thiab overheating, ua kom muaj kev nyab xeeb thiab txuas ntxiv roj teeb lub neej.
Ib qho peb -tier architecture feem ntau yog siv: BMU (Bag Level) → BCMU (Cluster Level) → BAMU (Battery Level) kom ua tau raws li tus kheej ntawm tes ntsuas, kev ceeb toom txhaum cai, thiab qhov system-widecontrol.
3. Zog Cia Converter (PCS, lub "converter" ntawm lub zog)
Lub PCS ua rau kev hloov pauv bidirectional ntawm qhov ncaj qha tam sim no (DC) thiab hloov pauv tam sim no (AC), thiab yog lub cuab yeej tseem ceeb txuas lub roj teeb rau hauv daim phiaj.
Muaj nuj nqi: Kev them nyiaj / tso tawm tswj, kab hluav taws xob- txuas / tawm- daim phiaj hloov pauv, kev tswj hwm lub zog / rov ua haujlwm. Txhawb millisecond- qib hloov pauv thiab koom nrog hauv kev tswj hwm kab sib chaws, kev txhawb nqa hluav taws xob, thiab lwm yam kev pabcuam ntxiv.
