Iyo BMS bhatiri manejimendi system ingori mutariri webhatiri, ichiita basa rakakosha mukuchengetedza kuchengetedzwa, kuwedzera hupenyu hwesevhisi uye kufungidzira simba rasara.Icho chinhu chakakosha chesimba uye chekuchengetedza bhatiri mapaketi, kuwedzera hupenyu hwebhatiri kune imwe nhanho uye kuderedza kurasikirwa kunokonzerwa nekukuvara kwebhatiri.
Simba rekuchengetedza bhatiri manejimendi masisitimu akafanana zvakanyanya nemagetsi mabhatiri manejimendi masisitimu.Vanhu vazhinji havazive mutsauko uripo pakati pesimba rebhatiri BMS manejimendi system uye yekuchengetera simba bhatiri BMS manejimendi system.Tevere, sumo pfupi yekusiyana pakati pesimba bhatiri BMS manejimendi masisitimu uye ekuchengetedza simba bhatiri BMS manejimendi masisitimu.
1. Bhatiri nehurongwa hwayo hwekutarisira nzvimbo dzakasiyana mumasisitimu anoenderana
Musimba rekuchengetedza simba, bhatiri rekuchengetedza simba rinongopindirana neiyo yakakwira voltage simba rekuchengetedza, iyo inotora simba kubva kune AC grid uye inochaja bhatiri pack, kana bhatiri paki rinopa chinoshandura uye simba remagetsi rinoshandurwa kuita AC grid. kuburikidza ne converter.
Iyo yekukurukurirana uye bhatiri manejimendi system yesimba rekuchengetedza sisitimu ine ruzivo rwekudyidzana kunyanya neinoshandura uye yekuronga sisitimu yesimba rekuchengetedza simba.Kune rimwe divi, iyo bhatiri manejimendi system inotumira yakakosha mamiriro eruzivo kune inoshandura kuona mamiriro eiyo yakakwira-voltage simba rekudyidzana uye, kune rimwe divi, iyo bhatiri manejimendi system inotumira iyo yakazara yakazara yekutarisa ruzivo kuPCS, iyo kutumira. hurongwa hwenzvimbo yekuchengetedza simba.
Motokari yemagetsi BMS ine hukama hwekutsinhana kwesimba nemota yemagetsi uye charger maererano nekutaurirana pamhepo yakakwira, ine ruzivo rwekudyidzana nechaja panguva yekuchaja uye ine ruzivo rwakanyanya ruzivo rwekudyidzana nemutongi wemotokari panguva yese yekushandisa.
2. Chimiro chinonzwisisika che hardware chakasiyana
Kune masisitimu ekuchengetedza ekuchengetedza simba, iyo Hardware inowanzo mune maviri- kana matatu-tier modhi, ine chiyero chakakura chinotarisa kune matatu-tier manejimendi masisitimu. Simba bhatiri manejimendi masisitimu anongova nechikamu chimwe chete chepakati kana maviri akagoverwa, uye anenge asina matatu matatu.Mota diki dzinonyanya kushandisa centralized bhatiri manejimendi masisitimu.Maviri-layer akagoverwa simba bhatiri manejimendi system.
Kubva pamaonero anoshanda, yekutanga uye yechipiri layer modules yesimba rekuchengetedza bhatiri manejimendi system yakanyatso yakaenzana neyekutanga layer yekuunganidza module uye yechipiri layer master control module yebhatiri remagetsi.Iyo yechitatu dhizaini yekuchengetedza bhatiri manejimendi system ndeye yekuwedzera layer pamusoro peiyi, inotarisana nehukuru hukuru hwebhatiri rekuchengetedza.Inoratidzwa musimba rekuchengetedza bhatiri manejimendi system, iyi manejimendi kugona isimba re computational re chip uye kuoma kwesoftware chirongwa.
3. Mitemo yekukurukurirana yakasiyana
Simba rekuchengetedza bhatiri manejimendi system uye kutaurirana kwemukati kunonyanya kushandisa CAN protocol, asi nekutaura kwekunze, zvekunze zvinonyanya kureva simba rekuchengetedza simba chirimwa kuronga system PCS, kunyanya kushandisa iyo Internet protocol fomu TCP/IP protocol.
Simba bhatiri, nzvimbo yakawanda yemotokari dzemagetsi dzinoshandisa CAN protocol, chete pakati pezvikamu zvemukati zvebheteri pack uchishandisa mukati meCAN, bhatiri pack uye motokari yose pakati pekushandiswa kwemotokari yose CAN kusiyanisa.
4.Ddifferent mhando dzemacores anoshandiswa mumagetsi ekuchengetedza magetsi, iyo management system parameters inosiyana zvakanyanya
Zviteshi zvemagetsi ekuchengetedza magetsi, uchifunga nezvekuchengetedza uye hupfumi, sarudza mabhatiri e lithium, kazhinji lithium iron phosphate, uye mamwe magetsi ekuchengetedza magetsi anoshandisa mabhatiri ekutungamirira uye lead-carbon mabhatiri.Iyo yakakura bhatiri mhando yemotokari dzemagetsi ikozvino lithium iron phosphate uye ternary lithium mabhatiri.
Mhando dzakasiyana dzebhatiri dzine hunhu hwakasiyana hwekunze uye mhando dzebhatiri hadzina kujairika zvachose.Battery manejimendi masisitimu uye yakakosha paramita inofanirwa kuenderana imwe kune imwe.Iwo akadzama ma paramita akaiswa zvakasiyana kune imwechete mhando yepakati inogadzirwa nevagadziri vakasiyana.
5. Maitiro akasiyana-siyana mukugadzirisa zvikumbaridzo
Zviteshi zvemagetsi ekuchengetedza magetsi, uko nzvimbo yakawandisa, inogona kugadzirisa mabhatiri akawanda, asi nzvimbo iri kure yezvimwe zviteshi uye kusagadzikana kwekutakura kunoita kuti zviome kutsiva mabhatiri pamwero mukuru.Tarisiro yesimba rekuchengetedza simba chiteshi ndechekuti masero ebhatiri ane hupenyu hurefu uye haakundike.Pamusoro pechikonzero ichi, muganho wepamusoro wekushanda kwavo ikozvino wakaiswa zvishoma kuti udzivise basa rekutakura magetsi.Hunhu hwesimba uye masimba masimba emaseru hazvifanirwe kunge zvichinyanya kudiwa.Chinhu chikuru chekutsvaga ndechekubhadhara mari.
Masero emagetsi akasiyana.Mumotokari ine nzvimbo shoma, bhatiri rakanaka rinoiswa uye huwandu hwehuwandu hwayo hunodiwa.Naizvozvo, iwo masisitimu maparamendi anoreva kugumira paramita yebhatiri, iyo isina kunaka kune bhatiri mumamiriro ekushandisa akadaro.
6. Izvo zviviri zvinoda mamiriro akasiyana ehurumende kuti averengerwe
SOC is a state parameter inoda kuverengerwa nevaviri.Nekudaro, kusvika nhasi, hapana yunifomu inodiwa yesimba rekuchengetedza masisitimu.Ndeipi mamiriro parameter kuverenga kugona kunodiwa kune simba rekuchengetedza bhatiri manejimendi masisitimu?Pamusoro pezvo, nharaunda yekushandisa yemabhatiri ekuchengetedza simba ine nzvimbo yakapfuma uye yakagadzikana kwezvakatipoteredza, uye kutsauka kudiki kwakaoma kuona mune yakakura sisitimu.Naizvozvo, iyo computational kugona zvinodiwa zvesimba rekuchengetedza bhatiri manejimendi masisitimu akadzikira pane ayo emagetsi mabhatiri manejimendi masisitimu, uye inoenderana imwe-tambo yekudzora bhatiri mutengo hauna kukwira semabhatiri emagetsi.
7. Simba rekuchengetedza bhatiri manejimendi masisitimu Kushandiswa kwezvakanaka passive balancing mamiriro
Magetsi emagetsi ekuchengetera magetsi ane chinodiwa chekukurumidzira kuenzana kwesimba rekutonga system.Eneji yekuchengetedza bhatiri modules yakakura muhukuru, ine akawanda tambo dzebhatiri dzakabatana munhevedzano.Makuru ega ega voltage akasiyana anoderedza huwandu hwebhokisi rese, uye iyo yakawanda mabhatiri munhevedzano, iyo yakawanda inorasikirwa nehukuru.Kubva pakuona kwehutano hwehupfumi, zvidyarwa zvekuchengetedza simba zvinoda kuenzana zvakakwana.
Mukuwedzera, passive balancing inogona kushanda zvakanyanya nenzvimbo yakawanda uye yakanaka yekupisa mamiriro, kuitira kuti mahombe ekuenzanisa mafungu anoshandiswa pasina kutya kwekukwira kwakanyanya kwekushisa.Yakaderera-mutengo passive balancing inogona kuita mutsauko mukuru mumagetsi ekuchengetedza simba zvidyarwa.
