6.BMS software architecture
lHigh uye yakaderera voltage management
Kana yagara ichibatidzwa, BMS inomutswa neVCU kuburikidza netambo yakaoma kana CAN chiratidzo che12V.Mushure mekunge BMS yapedza kuzviongorora uye ichipinda pakamira, VCU inotumira murairo wepamusoro-voltage, uye BMS inodzora kuvharwa kweiyo relay kuti ipedze kubatanidzwa kwepamusoro-voltage.Kana yadzimwa, VCU inotumira yakaderera-voltage command uye yobva yabvisa iyo 12V kumuka.Kana pfuti yaiswa kuti ichajise munzvimbo yekudzima simba, inogona kumutswa neCP kana A + chiratidzo.
lKuchaja manejimendi
(1) Kuchaja zvishoma nezvishoma
Kuchaja zvishoma nezvishoma ndiko kuchaja bhatiri necharizvino chashandurwa kubva pakuchinjanisa ikozvino ne-on-board charger yemurwi wekuchaja (kana 220V magetsi).Iyo mirwi yekuchaja yakajairika ndeye 16A, 32A, uye 64A, uye inogona zvakare kuchajwa kuburikidza nemagetsi epamba.Iyo BMS inogona kumutswa neCC kana CP chiratidzo, asi inofanirwa kuve nechokwadi kuti inogona kurara zvakajairika mushure mekuchaja kwapera.Iyo AC yekuchaja maitiro iri nyore uye inogona kugadzirwa zvinoenderana neyakadzama yenyika zviyero.
(2) Kuchaja nekukurumidza
Kuchaja nekukurumidza ndeyekuchaja bhatiri nechaji chazvino chabuda neDC yekuchaja murwi, iyo inogona kuwana 1C kana kunyange yakakwirira yekuchaja.Kazhinji, 80% yebhatiri inogona kuchajwa mumaminitsi makumi mana nemashanu.Inogona kumutswa neanobatsira simba sosi A + chiratidzo chemurwi wekuchaja.
lEstimation function
(1) SOP (State of Power) inonyanya kuwana bhatiri iripo yekuchaja uye yekuburitsa simba nekutarisa kumusoro kwematafura kuburikidza nekushisa uye SOC.VCU inosarudza mashandisirwo emotokari yese zvichibva pane kukosha kwesimba rakatumirwa.
(2) SOH (State of Health) inonyanya kuratidza hutano huripo hwebheteri, ine kukosha pakati pe0-100%.Zvinowanzoonekwa kuti bhatiri haigone kushandiswa mushure mekunge yadonha pasi pe80%.
(3) SOC (State of Charge) ndeyeiyo core control algorithm yeBMS, iyo inotaridza yazvino yasara chinzvimbo.Iyo inonyanya kuve yakavakirwa pane iyo ampere-awa yakakosha nzira uye EKF (yakawedzerwa Kalman sefa) algorithm, yakasanganiswa nemaitiro ekugadzirisa (seakavhurika-circuit voltage kururamisa, yakazara kuchaja kururamisa, kupera-kwe-charge kururamisa, kugadzirisa kugona pasi petembiricha dzakasiyana. uye SOH, nezvimwewo).
(4) SOE (State of Energy) algorithm haina kugadzirwa zvakanyanya nevagadziri vemumba kana kushandisa algorithms akareruka kuti awane chiyero chesimba rasara pasi pemamiriro ekunze kusvika kune yakanyanya kuwanikwa simba.Iri basa rinonyanya kushandiswa kufungidzira yasara rwendo rwekufamba.
lKuongororwa kwemhosva
Mhando dzakasiyana dzekukanganisa dzinosiyaniswa zvichienderana nekuita kwakasiyana kwebhatiri, uye matanho ekugadzirisa akasiyana anotorwa neBMS neVCU pasi peakasiyana mazinga ekukanganisa, akadai seyambiro, kudzikisira simba, kana kubviswa kwakananga kwemagetsi akakwira.Mhosho dzinosanganisira kutora data uye kutadza kwehungwaru, kutadza kwemagetsi (sensors uye actuators), kukanganisa kutaurirana, uye kukanganisa mamiriro ebhatiri, nezvimwe.
