4. Ibikorwa byingenzi bya software ya BMS
l Igikorwa cyo gupima
. Igikorwa cyibanze cyane muri sisitemu yo gucunga bateri ni ugupima voltage, ikigezweho, nubushyuhe bwa selile ya batiri, ikaba ishingiro ryibiharuro byose byo murwego rwo hejuru no kugenzura logique ya sisitemu yo gucunga bateri.
.
. Iyo ubunyangamugayo bwa sisitemu yo hejuru ya voltage yangiritse, ingamba zumutekano zirakorwa.
lIgikorwa cyo kugereranya
(1) Ikigereranyo cya SOC na SOH: igice cyibanze kandi kigoye cyane

.
lIndi mirimo
(1) Igenzura rya relay: harimo nyamukuru +, nyamukuru-, kwishyuza relay +, kwishyuza -
(2) Kugenzura Ubushyuhe
(3) Igikorwa cyitumanaho
(4) Gusuzuma amakosa no gutabaza
(5) Igikorwa cyihanganira amakosa

6.BMS yububiko
lGucunga hejuru kandi ntoya
Iyo bisanzwe bikoreshwa, BMS ikangurwa na VCU ikoresheje umurongo ukomeye cyangwa CAN ikimenyetso cya 12V. BMS imaze kurangiza kwisuzuma ikinjira muri standby, VCU yohereza itegeko ryumubyigano mwinshi, kandi BMS igenzura ifunga rya relay kugirango irangize umuyagankuba mwinshi. Iyo amashanyarazi, VCU yohereza itegeko rya voltage nkeya hanyuma igahagarika 12V kubyuka. Iyo imbunda yinjijwe kugirango yishyure muri reta-power, irashobora gukangurwa nikimenyetso cya CP cyangwa A +.
lUbuyobozi bwo kwishyuza
(1) Kwishyuza buhoro
Kwishyuza gahoro ni ukwishyuza bateri hamwe numuyoboro utaziguye wahinduwe uva kumuyoboro uhinduranya na bisi ya charger yumuriro wikirundo (cyangwa 220V itanga amashanyarazi). Ikirundo cyo kwishyuza ibisobanuro ni 16A, 32A, na 64A, kandi birashobora no kwishyurwa binyuze mumashanyarazi yo murugo. BMS irashobora gukangurwa nikimenyetso cya CC cyangwa CP, ariko igomba kwemezwa ko ishobora gusinzira bisanzwe nyuma yo kwishyuza birangiye. Uburyo bwo kwishyuza AC buroroshye kandi burashobora gutezwa imbere ukurikije amahame arambuye yigihugu.
(2) Kwishyuza byihuse
Kwishyuza byihuse ni ukwishyuza bateri hamwe nibisohoka bitaziguye na DC yishyuza ikirundo, gishobora kugera kuri 1C cyangwa nigiciro cyo hejuru cyo kwishyuza. Mubisanzwe, 80% ya bateri irashobora kwishyurwa muminota 45. Irashobora gukangurwa ninkomoko yingufu zingirakamaro A + ikimenyetso cyumuriro.
lIgikorwa cyo kugereranya
(1) SOP. VCU igena uburyo ikinyabiziga cyose gikoreshwa hashingiwe ku gaciro kwoherejwe.
(2) SOH (Leta yubuzima) iranga cyane cyane ubuzima bwubu bwa bateri, hamwe nagaciro kari hagati ya 0-100%. Mubisanzwe bifatwa ko bateri idashobora gukoreshwa nyuma yo kugabanuka munsi ya 80%.
(3) SOC (Leta ishinzwe) ni iy'ibanze igenzura algorithm ya BMS, iranga ubushobozi busigaye busigaye. Ishingiye cyane cyane kuburyo bwa ampere-isaha yuburyo bwuzuye hamwe na algorithm ya EKF (yaguye ya Kalman iyungurura), ihujwe ningamba zo gukosora (nko gukosora amashanyarazi afunguye, gukosora byuzuye, gukosora amaherezo, gukosora ubushobozi mubushyuhe butandukanye na SOH, nibindi).
. Iyi mikorere ikoreshwa cyane cyane mukugereranya intera isigaye.
lGusuzuma amakosa
Inzego zinyuranye zitandukanijwe ukurikije imikorere itandukanye ya bateri, kandi ingamba zitandukanye zo gutunganya zifatwa na BMS na VCU murwego rwamakosa atandukanye, nko kuburira, kugabanya ingufu, cyangwa guhagarika amashanyarazi menshi. Amakosa arimo gushaka amakuru no gushyira mu gaciro, amakosa y'amashanyarazi (sensor na actuator), amakosa y'itumanaho, n'amakosa ya bateri, nibindi.
