6.BMS software architecture
lKutarisira magetsi akakwira uye akaderera
Kana ichishandiswa nguva dzose, BMS inomutswa neVCU kuburikidza netambo yakaoma kana chiratidzo cheCAN che12V. Mushure mekunge BMS yapedza kuzviongorora uye yapinda mu standby, VCU inotumira murairo we high-voltage, uye BMS inodzora kuvharwa kwe relay kuti ipedzise kubatana kwe high-voltage. Kana yadzimwa, VCU inotumira murairo we low-voltage uye yobva yabvisa 12V wake-up. Kana pfuti yaiswa kuti ichajiswe mu power-off state, inogona kumutswa ne CP kana A+ signal.
lKutarisira kuchaja
(1) Kuchaja zvishoma nezvishoma
Kuchaja zvishoma nezvishoma kunoreva kuchaja bhatiri nemagetsi akananga anoshandurwa kubva pamagetsi anochinjana nechaja iri mubhodhi yemurwi wekuchaja (kana kuti magetsi e220V). Magadzirirwo emurwi wekuchaja anowanzo kuve 16A, 32A, uye 64A, uye inogona zvakare kuchajwa kuburikidza nemagetsi epamba. BMS inogona kumutswa neCC kana CP signal, asi inofanira kuve nechokwadi chekuti inogona kurara zvakanaka mushure mekunge chaja yapera. Maitiro ekuchaja AC ari nyore uye anogona kugadzirwa zvichienderana nezvinodiwa nenyika.
(2) Kuchaja nekukurumidza
Kuchaja nekukurumidza kunoreva kuchaja bhatiri nemagetsi anobuda zvakananga kubva mu DC charging pile, izvo zvinogona kusvika pa 1C kana kutopfuura mwero wekuchaja. Kazhinji, 80% yebhatiri inogona kuchaja mumaminitsi makumi mana nemashanu. Inogona kumutswa neA+ power source yemurwi wekuchaja.
lBasa rekufungidzira
(1) SOP (State of Power) inonyanya kuwana simba rekuchaja nekuburitsa bhatiri riripo nekutarisa matafura kuburikidza netembiricha uye SOC. VCU inosarudza kuti mota yese inoshandiswa sei zvichienderana nesimba rinotumirwa.
(2) SOH (State of Health) inonyanya kuratidza hutano hwebhatiri parizvino, ine kukosha kuri pakati pe0-100%. Kazhinji zvinofungidzirwa kuti bhatiri harigone kushandiswa kana radzikira pasi pe80%.
(3) SOC (State of Charge) ndeye core control algorithm yeBMS, iyo inoratidza mamiriro esimba razvino. Inonyanya kushandiswa pa ampere-hour integral method uye EKF (extended Kalman filter) algorithm, pamwe chete nemaitiro ekugadzirisa (akadai se open-circuit voltage correction, full charge correction, end-of-charge correction, capacity correction pasi petembiricha dzakasiyana uye SOH, nezvimwewo).
(4) Algorithm yeSOE (State of Energy) haina kugadzirwa zvakanyanya nevagadziri vemuno kana kushandisa maalgorithms ari nyore kuwana chiyero chesimba rasara pasi pemamiriro aripo iye zvino kune simba rakawanda riripo. Basa iri rinonyanya kushandiswa pakufungidzira huwandu hwekufamba kwechikepe hwasara.
lKuongororwa kwemhosva
Matanho akasiyana ekukanganisa anosiyaniswa zvichienderana nekushanda kwakasiyana kwebhatiri, uye matanho akasiyana ekugadzirisa anotorwa neBMS neVCU pasi pematanho akasiyana ekukanganisa, akadai sekuyambira, kuganhurirwa kwesimba, kana kudzima zvakananga voltage yakakwira. Zvikanganiso zvinosanganisira zvikanganiso zvekuwana data uye kugona kunzwisisa, zvikanganiso zvemagetsi (masensa nemaactuator), zvikanganiso zvekutaurirana, uye zvikanganiso zvemamiriro ebhatiri, nezvimwewo.
