Battery manejimendi system kukanganisa kuongororwa!

Munyori: Iflowpower - Inotakurika Power Station Mutengesi

BatteryManagementSystem, inowanzozivikanwa sebhatiri muchengeti wemba kana bhatiri muchengeti wemba, chinhu chakakosha chekubatanidza bhatiri remagetsi emotokari uye mota yemagetsi. Iwo makuru mabasa anosanganisira: bhatiri physical parameters real-time monitoring; fungidziro yemamiriro ebhatiri; online kuongororwa uye yambiro; charge, discharge Precharge control; equalization manejimendi uye kupisa manejimendi, nezvimwe. Iyo bhatiri manejimendi sisitimu (BMS) inonyanya kuvandudza mashandisirwo ebhatiri, kudzivirira kudzivirira kwebhatiri uye kunyanya kuburitsa, kuwedzera hupenyu hwebhatiri, kutarisa mamiriro ebhatiri.

Iyo bhatiri manejimendi sisitimu haingori pedyo chete nebhatiri, asi zvakare ine akasiyana maitirwo neiyo mota system. Mukukanganisa kwese, zvikanganiso zvebhatiri manejimendi system zvakaenzana nepamusoro kune mamwe masisitimu, uye zvakare zvakaoma kugadzirisa. Xiaobian inopfupikisa dzimwe nzira dzakajairika dzekugadzirisa mabhatiri manejimendi masisitimu uye zvikanganiso zvakajairika zvebhatiri manejimendi masisitimu, ekushandisa, bhatiri, bhatiri, manejimendi system vagadziri.

BMS Fault Analysis Method yekucherekedza nzira Kana sisitimu yavhiringwa kana kudzorwa, inorira, uye pane chiratidzo chealarm pachiratidziro. Mhosva Resequences Kukanganisa kwemotokari pasi pemamiriro akasiyana akasiyana. Kana mamiriro ezvinhu akabvumirwa, dambudziko rinosimbiswa zvakanyanya sezvinobvira pasi pemamiriro akafanana, uye rinotsigira dambudziko dambudziko.

Kana mutemo wacho wakafanana nekupindira, zvikamu zvakasiyana-siyana muhurongwa zvinofanira kubviswa chimwe nechimwe kuti chione kuti chikamu chipi chinokanganisa hurongwa. Kutsiviwa nzira Kana moduru isina kujairika, chinzvimbo chemodule chetambo dzakafanana chinoshandurwa, uye kuongororwa idambudziko remodule kana dambudziko remashini. Kana sisitimu yakanganisa, kana sisitimu isingagone kuratidzwa, ngatiregei Kukurumidzira kufunga, nekuti isu tinowanzo kufuratira zvimwe zvinhu.

Kutanga tinofanira kutarisa zvinhu izvozvo: kana paine chero magetsi? Switch yakavhurwa here? Mawaya ese akabatana here? Zvichida mudzi wedambudziko uri pano. Purogiramu Yekuvandudza Mutemo Kana pane kusakundikana kusingazivikanwi mushure mokunge purogiramu itsva yapiswa, inokonzera hurongwa kudzora chisizvo, uye inogona kupisa shanduro yapfuura yepurogiramu kuenzanisa kuongororwa nekugadzirisa kukanganisa. Data Analysis Kana iyo BMS inodzora kana kukanganisa kwakabatana, data reBMS rekuchengetedza rinogona kuongororwa, uye zviri mukati memeseji mubhazi reCAN zvinoongororwa.

Common fault case analysis 1. Iyo yese sisitimu haishande mushure meiyo system simba rekupa inogona kukonzera abnormal magetsi, uye waya harness ipfupi kana kutyoka, uye DCDC haina voltage inobuda. Troubleshooting Tarisa kana simba rekunze rinowanikwa rakajairwa, kana richikwanisa kuwana hushoma hwekushandisa voltage inodiwa nehurongwa hwekutungamira, ona kana magetsi ekunze ari mashoma, zvichikonzera kusakwana kwemagetsi kune manejimendi system; gadzirisa magetsi ekunze kuti asangane nehurongwa hwekutarisira Magetsi emagetsi zvinodiwa; tarisa kana iyo harness yehurongwa hwekutarisira ine pfupi pfupi kana dunhu rakaputsika, shandura iyo harness, ichiita yakajairika; magetsi ekunze uye harness zvakajairika, wobva waona iyo DCDC yakapihwa kune yese system kuti ipe iyo yese system DCDC; Kana paine abnormality inotsiva DCDC module.

2, BMS haigone kutaurirana neECU (Master Module) haishande, CAN chiratidzo mutsara disconnection troubleshooting tarisa BMU simba rekupa 12V / 24V yakajairika; tarisa kana iyo CAN chiratidzo chekufambisa mutsara ichidzokera kana plug isina kuiswa; teerera kuCAN port Data, zvinoita here kugamuchira BMS kana ECU packet. 3, BMS neECU kusagadzikana kwekukurukurirana kunogoneka kunokonzera kunze kweCAN bhazi machisi, bazi rebhazi rakareba, bhazi rekuona rinoenderana nekupikisa chaiko; kana chinzvimbo chekufananidza chakarurama, bazi rakareba. 4, BMS yemukati yekusagadzikana yekusagadzikana inogona kukonzera yekutaurirana plug plug, iyo CAN mutsara haina kumira, iyo BSU kero inodzokorora.

Troubleshooting Detection Wiring yakasununguka; bhazi rekuona rinoenderana nekupikisa kwakarurama, nzvimbo inofananidzwa yakarurama, kana bazi rakareba; tarisa kana kero yeBSU inodzokororwa. 5, insulation test alarm inogona kukonzera bhatiri kana dhiraivha kubuda. , Insulation module yekuona mutsara kukanganisa.

Troubleshoot Shandisa iyo BDU kuratidza module kuti utarise kuvharidzira data data, tarisa kana bhatiri bhazi voltage yakajairika, ingave yepasi voltage yakajairika; shandisa insulated wachi wachi kuyera busbar uye kutyaira kune pasi insulation kuramba. 6, mushure mesimba-pa, iyo huru relay haina kunyura muchikonzero chemutsetse wekuona mutsara, precharger yakavhurika, precharge kuramba yakavhurika. Troubleshooting Shandisa BDU kuratidza module kuona bhazi voltage data, tarisa bhatiri bhazi voltage, kana mutoro bhazi voltage yakajairika; tarisa kana iyo bhazi inotakura voltage iri kukwira panguva ye pre-charge process.

7, iyo yekutora module data ndeye 0 zvinokonzeresa kuti iyo yekutora module yekutora mutsara ibvise, kuunganidza mamodule huori. Troubleshooting Reploys iyo module wiring, kuyera kana bhatiri voltage iri yakajairika pane yekutora tambo yekubatanidza, yakajairika kuyera kana kukosha kwekupokana kwakajairika pane tembiricha sensor line plug. 8, bhatiri yazvino data kukanganisa kunogona kukonzera iyo Horo siginecha mutsara plug kusununguka, Horo sensor yakakuvadzwa, iyo yekutora module yakuvadzwa.

Troubleshooting Reploquest Carter Sensor Signal; Tarisa kana iyo Imba sensor yakajairika, kana iyo chiratidzo inobuda yakajairika; tsiva iyo yekutora module. 9. Musiyano wetembiricha yebhatiri wakakurisa.

Kukonzeresa Conditioning fan plug kusunungura, kutonhodza fan kutadza. Kugadzirisa dambudziko kunopindirana zvakare mutsetse we plug fan; govera fan zvakasiyana, tarisa kana fan iri yakajairika. 10, tembiricha yebhatiri yakawandisa kana yakaderera inogona kukonzera kupisa kupisa fan plug kuregedzera, kutonhora kwe fan fan, kukuvara kwe tembiricha.

Kugadzirisa mutsara we plug fan; govera fan zvakasiyana, tarisa kana fan iri yakajairika; tarisa kana tembiricha chaiyo yebhatiri yakanyanya kana kuderera; kuyera kupikisa kwemukati kweprobe yekushisa. 11. Mushure mekushanda kwerelay, iko kukanganisa kwehurongwa kunogona kukonzera relay yekubatsira yekubatanidza yekubvisa mutsara, relay yekubata adhesion dambudziko reinterproving iyo harness; kuyera vabatsiri vanobatika mu multimeter.

12. Haukwanisi kushandisa muchina wekuchaja kuchaja zvikonzero zvinoita kuti muchina wekuchaja hausi wenguva dzose kugadzirisa nhaurirano yeBMS kutsiva charger kana BMS kuratidza kuti BMS yakanganisa here kana kuti kuchaja kutadza; tarisa kana kuenzanisa kwekupokana kweBMS yekuchaja port kwakajairika. 13.

Inboard mita Hapana BMS Data Ratidza Inogoneka Chikonzero Chikuru Kudzora Module Wire Beam Connection Abnormal Troubleshooting Tarisa kana iyo huru control module harness yakabatana, ine yakaderera-voltage yekushanda voltage yemotokari, ingave iyo module inoshanda zvakajairika 14, imwe bhatiri bhokisi rekuona data Kurasika kunogona kukonzera akasiyana ekubatanidza anogona kunge ari kusangana neasina dhiri dhizaini, kana BMS inobata nyaya yakaoma, kana BMS inobata basa rakaoma, kana BMS inobata nyaya yakaoma. module;. 15. SOC chiitiko chisina kujairika: SOC inosiyana zvakanyanya panguva yekushanda sisitimu, kana kudzokororwa yakasvetuka pakati pezvakawanda zvakakosha; muhurongwa hwekuchaja uye kuburitsa maitiro, SOC ine kutsauka kukuru; SOC yagara ichiratidza zvimiro zvenhamba.

Chingangove chikonzero chazvino hachina kurongeka; iyo yazvino sensor modhi haienderane nechirongwa chekugamuchira; bhatiri haina kudzika kubhadharisa uye kubuda; iyo data yekutora module inounganidza kusvetuka, zvichiita kuti SOC iite otomatiki; mamiriro maviri eSOC calibration: 1) svika pakudzivirira kwepamusoro; 2 ) Avhareji yemagetsi inosvika paXXV kana kupfuura. Mutengi bhatiri kuenderana kwakashata, uye chimiro chechipiri hachigone kusvika. Nekuratidza huwandu hwasara uye huwandu hwakazara hwebhatiri; iyo sensor yazvino haina kubatana nemazvo; kugadzirisa dambudziko: Calibrate ikozvino mune yekubata skrini yekumisikidza peji; shandura chirongwa chekugamuchira kana kutsiva ikozvino sensor; kudzika kwakadzika uye kubuda kwebhatiri; tsiva iyo data yekutora module, Iyo system SOC inorongedzerwa nemaoko.

Zvinokurudzirwa kuti vatengi vave nekuchaja kwakadzika uye kuburitsa vhiki yega yega; shandura chirongwa chekugamuchira, gadzirisa "Average Voltage kuXXV kana kupfuura" zvichienderana nemamiriro chaiwo emutengi XXV. Seta iyo chaiyo bhatiri huwandu uye huwandu hwasara; batanidza nemazvo sensor yazvino kuti ishande nemazvo. .
