Kodi ntchito yaBMS?
Pali ntchito zambiri za BMS, ndipo zofunika kwambiri, zomwe timaziganizira kwambiri, ndi zinthu zitatu zokha: kasamalidwe ka udindo, kasamalidwe koyenera, ndi kasamalidwe ka chitetezo.
Ntchito yoyang'anira boma yanjira yoyendetsera batire
Tikufuna kudziwa momwe batire ilili, mphamvu yake ndi yotani, mphamvu yake ndi yotani, mphamvu yake ndi yotani, komanso mphamvu yake ndi yotani, ndipo ntchito yoyang'anira boma la BMS idzatiuza yankho. Ntchito yoyambira ya BMS ndikuyesa ndikuyerekeza magawo a batire, kuphatikiza magawo oyambira ndi momwe zinthu zilili monga mphamvu yake, mphamvu yake, ndi kutentha kwake, komanso kuwerengera deta ya momwe batire ilili monga SOC ndi SOH.
Kuyeza kwa maselo
Kuyeza chidziwitso choyambira: Ntchito yofunikira kwambiri ya dongosolo loyendetsera batri ndikuyesa mphamvu yamagetsi, mphamvu yamagetsi, ndi kutentha kwa selo ya batri, zomwe ndi maziko a kuwerengera kwapamwamba ndi njira zowongolera za machitidwe onse oyang'anira batri.
Kuzindikira kukana kwa kutentha: Mu dongosolo loyang'anira mabatire, kuzindikira kutentha kwa dongosolo lonse la batire ndi dongosolo lamagetsi amphamvu ndikofunikira.
Kuwerengera kwa SOC
SOC imatanthauza State of Charge, mphamvu yotsala ya batri. Mwachidule, ndi kuchuluka kwa mphamvu zomwe zatsala mu batri.
SOC ndiye gawo lofunika kwambiri mu BMS, chifukwa china chilichonse chimadalira SOC, kotero kulondola kwake ndikofunikira kwambiri. Ngati palibe SOC yolondola, palibe kuchuluka kwa ntchito zotetezera zomwe zingapangitse BMS kugwira ntchito bwino, chifukwa nthawi zambiri batire imatetezedwa, ndipo nthawi ya batire singathe kukulitsidwa.
Njira zodziwika bwino zowerengera za SOC zikuphatikizapo njira yotsegulira magetsi, njira yolumikizira magetsi, njira yosefera ya Kalman, ndi njira ya netiweki ya neural. Njira ziwiri zoyambirira zimagwiritsidwa ntchito kwambiri.
Ntchito yoyang'anira bwino ndalama zanjira yoyendetsera batire
Batire iliyonse ili ndi "umunthu" wake. Kuti tikambirane za kulinganiza, tiyenera kuyamba ndi batire. Ngakhale mabatire opangidwa ndi wopanga yemweyo mu batch yomweyo ali ndi moyo wawo komanso "umunthu" wawo - mphamvu ya batire iliyonse singakhale yofanana kwenikweni. Pali mitundu iwiri ya zifukwa zomwe zimapangitsa kusalingana kumeneku:
Kusasinthasintha kwa kupanga maselo ndi kusagwirizana kwa machitidwe a electrochemical
kusagwirizana kwa kupanga
Kusasinthasintha kwa kupanga kumamveka bwino. Mwachitsanzo, mu njira yopangira, zinthu zolekanitsa, cathode, ndi anode sizigwirizana, zomwe zimapangitsa kuti mphamvu yonse ya batri isagwirizane.
Kusasinthasintha kwa ma elekitiroma kumatanthauza kuti pakuchaja ndi kutulutsa batri, ngakhale kupanga ndi kukonza mabatire awiriwa kuli kofanana, malo otentha sangafanane panthawi ya electrochemical reaction.
Tikudziwa kuti kutchaja kwambiri ndi kutulutsa mphamvu kwambiri kungawononge kwambiri batire. Chifukwa chake, batire B ikadzaza ndi mphamvu zonse ikachaja, kapena SOC ya batire B ikachepa kale ikachaja, ndikofunikira kuyimitsa kutchaja ndi kutulutsa mphamvu kuti muteteze batire B, ndipo mphamvu ya batire A ndi batire C sizingagwiritsidwe ntchito mokwanira. Izi zimapangitsa kuti:
Choyamba, mphamvu yeniyeni yogwiritsira ntchito batire yachepa: mphamvu yomwe mabatire A ndi C akanatha kugwiritsa ntchito, koma tsopano palibe malo ogwiritsira ntchito mphamvu kuti asamalire B, monga momwe anthu awiri ndi miyendo itatu amamangirira yayitali ndi yayifupi pamodzi, ndipo masitepe a wamtali ndi ochedwa. Sangathe kupita patsogolo kwambiri.
Kachiwiri, moyo wa batire umachepa: kuyenda kwake kumakhala kochepa, kuchuluka kwa masitepe ofunikira kuyenda kumakhala kochulukirapo, ndipo miyendo imakhala yotopa kwambiri; mphamvu yake imachepa, ndipo kuchuluka kwa ma cycle omwe amafunika kuyikidwa ndi kutulutsidwa kumawonjezeka, ndipo kuchepa kwa batire kumakulirakuliranso. Mwachitsanzo, batire imodzi imatha kufika ma cycle 4000 ngati ikuyikidwa ndi kutulutsidwa 100%, koma singafikire 100% pakugwiritsa ntchito kwenikweni, ndipo kuchuluka kwa ma cycle sikuyenera kufika nthawi 4000.
Pali njira ziwiri zazikulu zoyezera BMS, kulinganiza zinthu mopanda mphamvu (passive balancing) ndi kulinganiza zinthu mogwira ntchito (active balancing).
Mphamvu yamagetsi yoyezera mphamvu yamagetsi ndi yaying'ono, monga mphamvu yamagetsi yoperekedwa ndi DALY BMS, yomwe ili ndi mphamvu yamagetsi yokwanira ya 30mA yokha komanso nthawi yayitali yoyezera mphamvu yamagetsi ya batri.
Mphamvu yolumikizira yogwira ntchito ndi yayikulu, mongachowongolera chogwira ntchitoYopangidwa ndi DALY BMS, yomwe imafika pamlingo wolinganiza wa 1A ndipo imakhala ndi nthawi yochepa yolinganiza mphamvu ya batri.
Ntchito yotetezanjira yoyendetsera batire
Chowunikira cha BMS chimagwirizana ndi zida zamagetsi. Malinga ndi momwe batire imagwirira ntchito, imagawidwa m'magawo osiyanasiyana a zolakwika (zolakwika zazing'ono, zolakwika zazikulu, zolakwika zakupha), ndipo njira zosiyanasiyana zogwirira ntchito zimatengedwa pansi pa magawo osiyanasiyana a zolakwika: chenjezo, malire a mphamvu kapena kudula mphamvu yamagetsi yayikulu mwachindunji. Zolakwika zimaphatikizapo kupeza deta ndi zolakwika zomwe zingatheke, zolakwika zamagetsi (masensa ndi ma actuator), zolakwika zolumikizirana, ndi zolakwika za momwe batire ilili.
Chitsanzo chodziwika bwino ndi chakuti batire ikatenthedwa kwambiri, BMS imaweruza kuti batireyo yatenthedwa kwambiri kutengera kutentha kwa batire komwe kwasonkhanitsidwa, kenako dera lolamulira batire limachotsedwa kuti lichite chitetezo cha kutentha kwambiri ndikutumiza alamu ku EMS ndi machitidwe ena oyang'anira.
Chifukwa chiyani muyenera kusankha DALY BMS?
DALY BMS, ndi imodzi mwa makampani akuluakulu opanga makina oyendetsera mabatire (BMS) ku China, ili ndi antchito oposa 800, malo opangira zinthu okhala ndi malo okwana masikweya mita 20,000 komanso mainjiniya ofufuza ndi chitukuko oposa 100.
