Kodi Battery Management System (BMS) ndi chiyani?
Dzina lonse laBMSndi Battery Management System, kasamalidwe ka batri. Ndi chipangizo chomwe chimagwirizana ndi kuyang'anira mkhalidwe wa batri yosungira mphamvu. Ndizoyang'anira mwanzeru ndi kukonza batire iliyonse, kuteteza batire kuti lisachuluke komanso kutulutsa mopitilira muyeso, kukulitsa moyo wautumiki wa batire, ndikuwunika momwe batire ilili. Nthawi zambiri, BMS imayimiridwa ngati bolodi lozungulira kapena bokosi la hardware.
BMS ndi imodzi mwamagawo apakati amagetsi osungira mphamvu ya batri. Ili ndi udindo woyang'anira magwiridwe antchito a batire iliyonse mubatire mphamvu yosungirakounit kuonetsetsa ntchito yotetezeka ndi yodalirika ya unit yosungirako mphamvu. BMS imatha kuyang'anira ndikusonkhanitsa magawo aboma a batire yosungira mphamvu munthawi yeniyeni (kuphatikiza koma osachepera mphamvu ya batri imodzi, kutentha kwa batire, kuchuluka kwa batire, mphamvu yamagetsi yamagetsi amagetsi batire paketi, kukana kwachitetezo cha batri, ndi zina), ndikupanga kufunikira Malinga ndi kusanthula ndi kuwerengera kwa dongosolo, magawo owunikira ambiri amapezedwa, ndikuwongolera koyenera kwabatire yosungirako mphamvuthupi limakwaniritsidwa molingana ndi njira yoyendetsera chitetezo, kuti zitsimikizire kuti ntchito yotetezeka komanso yodalirika ya batri yonse yosungira mphamvu. Panthawi imodzimodziyo, BMS ikhoza kusinthanitsa zidziwitso ndi zipangizo zina zakunja (PCS, EMS, chitetezo cha moto, ndi zina zotero) kupyolera mu mawonekedwe ake olankhulirana, kulowetsa kwa analogi / digito, ndi mawonekedwe olowetsamo, ndi kupanga kuwongolera kugwirizana kwa magawo osiyanasiyana mu malo onse osungiramo magetsi kuti atsimikizire chitetezo ndi kudalirika kwa malo opangira magetsi, ntchito yolumikizidwa bwino ndi gululi.
Kodi ntchito yake ndi chiyaniBMS?
Pali ntchito zambiri za BMS, ndipo zazikulu kwambiri, zomwe timakhudzidwa nazo kwambiri, sizoposa mbali zitatu: kasamalidwe ka chikhalidwe, kasamalidwe kabwino, ndi kasamalidwe ka chitetezo.
State Management ntchito yakasamalidwe ka batri
Tikufuna kudziwa momwe batire ilili, mphamvu yamagetsi ndi chiyani, mphamvu zingati, kuchuluka kwa mphamvu, komanso kuchuluka kwa ndalama ndi kutulutsa pakali pano, ndipo ntchito yoyang'anira boma la BMS idzatiuza yankho. Ntchito yayikulu ya BMS ndikuyesa ndikuyerekeza magawo a batri, kuphatikiza magawo oyambira ndi mayiko monga voliyumu, pakali pano, ndi kutentha, komanso kuwerengera deta yamtundu wa batri monga SOC ndi SOH.
Muyeso wa maselo
Muyezo wa zidziwitso zoyambira: Ntchito yofunikira kwambiri ya kasamalidwe ka batire ndikuyesa mphamvu yamagetsi, yapano, ndi kutentha kwa batire, yomwe ndi maziko a kuwerengera kwapamwamba komanso kuwongolera kwa machitidwe onse owongolera mabatire.
Kuzindikira kukana kwa insulation: mu kasamalidwe ka batri, kuwunikira kwa batire yonse ndi makina apamwamba kwambiri ndikofunikira.
Kuwerengera kwa SOC
SOC imatanthawuza State of Charge, mphamvu yotsalira ya batri. Mwachidule, ndi kuchuluka kwa mphamvu zomwe zatsala mu batri.
SOC ndiye gawo lofunikira kwambiri mu BMS, chifukwa china chilichonse chimachokera ku SOC, kotero kulondola kwake ndikofunikira kwambiri. Ngati palibe SOC yolondola, palibe kuchuluka kwa ntchito zoteteza zomwe zingapangitse BMS kugwira ntchito bwino, chifukwa batire nthawi zambiri imatetezedwa, ndipo moyo wa batri sungathe kupitilira.
Njira zamakono zowerengera za SOC zikuphatikiza njira yotseguka yamagetsi, njira yophatikizira yapano, njira yosefera ya Kalman, ndi njira ya neural network. Awiri oyambirira amagwiritsidwa ntchito kwambiri.
Balance management function yakasamalidwe ka batri
Batire iliyonse ili ndi "umunthu" wake. Kuti tilankhule za balance, tiyenera kuyamba ndi batire. Ngakhale mabatire opangidwa ndi wopanga yemweyo mugulu lomwelo amakhala ndi moyo wawo komanso "umunthu" wawo - mphamvu ya batire iliyonse singakhale yofanana ndendende. Pali mitundu iwiri ya zifukwa za kusagwirizanaku:
Kusagwirizana pakupanga ma cell ndi kusagwirizana kwa electrochemical reaction
kusagwirizana kwa kupanga
Kusagwirizana kwa kupanga kumamveka bwino. Mwachitsanzo, popanga, cholekanitsa, cathode, ndi zinthu za anode ndizosagwirizana, zomwe zimapangitsa kuti pakhale kusagwirizana kwa batri yonse.
Kusagwirizana kwa Electrochemical kumatanthauza kuti pakutha kwa batire ndikuthamangitsa, ngakhale kupanga ndi kukonza mabatire awiriwo kuli kofanana ndendende, chilengedwe chotentha sichingakhale chofanana panthawi ya electrochemical reaction.
Tikudziwa kuti kulipiritsa komanso kutulutsa kwambiri kumatha kuwononga kwambiri batire. Chifukwa chake, batire B ikakhala yokwanira pakuchapira, kapena SOC ya batire B yakhala yotsika kwambiri pakutulutsa, ndikofunikira kusiya kuyitanitsa ndi kutulutsa kuti muteteze batri B, ndipo mphamvu ya batire A ndi batire C sizingagwiritsidwe ntchito mokwanira. . Izi zimabweretsa:
Choyamba, Kuthekera kwenikweni kwa paketi ya batire kumachepetsedwa: mphamvu yomwe mabatire A ndi C akanatha kugwiritsa ntchito, koma tsopano palibenso kwina kogwiritsa ntchito mphamvu kuti asamalire B, monga momwe anthu awiri ndi miyendo itatu imamangiriza utali ndi afupikitsa pamodzi, ndipo masitepe a wamtali ndi odekha. Sindingathe kupita patsogolo.
Kachiwiri, Moyo wa paketi ya batri umachepetsedwa: ulendowu ndi wochepa, chiwerengero cha masitepe omwe amayenera kuyenda ndi ochulukirapo, ndipo miyendo imakhala yotopa kwambiri; mphamvu imachepetsedwa, ndipo kuchuluka kwa mizere yomwe ikufunika kuimbidwa ndi kutulutsidwa kumawonjezeka, ndipo kuchepetsedwa kwa batire kumakhalanso kwakukulu. Mwachitsanzo, selo limodzi la batri limatha kufika maulendo a 4000 pansi pa 100% ya malipiro ndi kutulutsa, koma silingathe kufika 100% pakugwiritsa ntchito kwenikweni, ndipo chiwerengero cha maulendo sayenera kufika nthawi za 4000.
Pali mitundu iwiri yayikulu yofananira ya BMS, kusanja mokhazikika komanso kusanja bwino.
Pakalipano pakufanana kwapang'onopang'ono ndi pang'ono, monga kufananitsa kwapang'onopang'ono koperekedwa ndi DALY BMS, komwe kumakhala ndi 30mA yokha komanso nthawi yayitali yofananira ndi batire.
The yogwira balancing panopa ndi yaikulu, mongayogwira balanceryopangidwa ndi DALY BMS, yomwe imafika pamlingo wa 1A ndipo imakhala ndi nthawi yayifupi yosinthira batire.
Chitetezo cha ntchitokasamalidwe ka batri
Chowunikira cha BMS chikufanana ndi zida zamagetsi zamagetsi. Malinga ndi magwiridwe antchito osiyanasiyana a batire, imagawidwa m'magawo osiyanasiyana olakwika (zolakwika zazing'ono, zolakwa zazikulu, zowopsa), ndipo njira zosiyanasiyana zosinthira zimatengedwa mosiyanasiyana molakwika: chenjezo, malire a mphamvu kapena kudula voteji mwachindunji. . Zolakwika ndi monga kupeza kwa data ndi zolakwika zomveka, kuwonongeka kwa magetsi (sensa ndi ma actuators), zovuta zolumikizirana, ndi kulephera kwa mawonekedwe a batri.
Chitsanzo chofala ndi chakuti batri ikatenthedwa kwambiri, BMS imaweruza kuti batire imatenthedwa molingana ndi kutentha kwa batire komwe kumasonkhanitsidwa, ndiyeno dera lomwe limayang'anira batire limachotsedwa kuti liteteze kutenthedwa ndikutumiza alamu ku EMS ndi machitidwe ena oyang'anira.
Chifukwa chiyani kusankha DALY BMS?
DALY BMS, ndi imodzi mwamakina akuluakulu oyendetsa mabatire (BMS) ku China, ili ndi antchito opitilira 800, malo opangira masikweya mita 20,000 ndi mainjiniya opitilira 100 a R&D. Zogulitsa zochokera ku Daly zimatumizidwa kumayiko ndi zigawo zopitilira 150.
