6.BMS software architecture
lKev tswj hwm hluav taws xob siab thiab qis
Thaum ib txwm siv hluav taws xob, BMS tau tsim los ntawm VCU ntawm txoj kab nyuaj lossis CAN teeb liab ntawm 12V.Tom qab BMS ua tiav kev kuaj xyuas tus kheej thiab nkag mus rau qhov muag, VCU xa cov lus txib siab, thiab BMS tswj qhov kaw ntawm relay kom tiav qhov kev sib txuas siab.Thaum fais fab tuag, VCU xa cov lus txib qis qis thiab tom qab ntawd txiav tawm 12V sawv.Thaum lub phom tso rau kev them nyiaj hauv lub xeev lub hwj chim tawm, nws tuaj yeem tsim los ntawm CP lossis A + teeb liab.
lKev tswj kev them nqi
(1) Kev them nyiaj qeeb
Kev them nqi qeeb yog kom them lub roj teeb nrog cov tam sim no ncaj qha hloov pauv los ntawm kev hloov pauv tam sim no los ntawm cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob (lossis 220V fais fab mov).Cov kev qhia tshwj xeeb ntawm pawg them nyiaj feem ntau yog 16A, 32A, thiab 64A, thiab nws tuaj yeem raug them los ntawm kev siv hluav taws xob hauv tsev.BMS tuaj yeem tsim los ntawm CC lossis CP teeb liab, tab sis nws yuav tsum tau xyuas kom meej tias nws tuaj yeem pw tsaug zog ib txwm tom qab them nyiaj tiav.Cov txheej txheem AC them nyiaj yog qhov yooj yim thiab tuaj yeem tsim tau raws li cov qauv hauv lub tebchaws.
