Kasi Kupima Kwasono nchivichi?
Waliyose uyo wagwira ntchito na BMS wawonaSOCkuŵazga uko kukuyana yayi na unenesko. Battery yikulongora 30% ndipo forklift wakufwa mwamabuchibuchi. Panji yikufika pa 80% ndipo yikudumphira mwaluŵiro. Kufufuza foramu yiliyose ndipo muzamusanga ulusi wakukhwaskana na "mabatire kukulongora 100% kweni muzamuyamba yayi" panji "kujara mwamabuchi pa 25% SOC." Kungaŵa kwambura kulinganizgika, kugaŵa viheni algorithm, panji vimembe vya BMS. Kweni chinthu chimoza kanandi chikuleka kuwoneka: chiyezgo cha sonosono apa chingaŵa kuti chazima.
Ŵikani resitini yakukwana pa mndandanda na dera, yezgani dontho la magesi, lembani Dango la Ohm. Resistor iyo yikuchemeka kuti shunt.
Mabatire gha EV na mafakitale ghakugwiriskira ncito shunts mu 25μΩ kufika pa 100μΩ. Chifukwa wuli nthena vili pasi? Kankha 6000 kwizira mu 0.5mΩ shunt ndipo mukulaŵiska pa 180W ya kugaŵa kutentha. Kutentha uko kukwenera kuluta ku malo ghanyake. Vipangizo vinandi vyakupangika vyapereka nthowa zakutentha kuzingilizga msonkhano wa nyengo yasono wa kumanya kuti umazge waka ivi.
Masensa gha Hall effect ghakupima mtundu wa maginiti uwo ukupangika na kuseŵera kwa sonosono apa m’malo mwa kuŵikika mu dera likuru. Kuzengeka - galvanic yekha. Kweni kulondola kukusuzgika pa nyengo yakucepa -a 1000A-zilo ya Hall module 10A yingalongora kubudiska kanandi waka kuluska pa 500A. Mapangidwe ghanandi gha BMS ghakugwiriskira ncito Hall backup, na shunts kucita kumanya kwakwamba.
Kupuma kwa nyengo na nyengo ni chigaŵa waka cha chithuzithuzi. BMS yikukhumbikwira SOC, iyo yikung’anamura kuti kuŵerengera magesi pa nyengo - coulomb kuŵerengera. Sampuli yili na phokoso na kuzimwa. Kuthamanga nyengo yitali mwakukwana ndipo viheni vikuwunjika. Nthowa zaunenesko zikusazgako coulomb kuŵerengera na shortage yakujulika - circuit cross- wonani, panji kugwiriskira ncito kusefa kwa Kalman. Kusunga SOC kupuvya mukati mwa 5% nchinthu cakumanyikwa comene.
Kupanga maselo pa fakitare kukukhumbikwira kuti kuŵe kwakukhora chomene sonosono apa kuluska BMS ya nyengo yakuchitira. Kupanga sonosono apa kukukhwaska mtundu wa SEI layer, uwo ukukhwaska kukhaliska kwa maselo pa batch. Malo ghakupangira vinthu ghakugwiriskira ncito- preprecisions na 24- bit ADCs. Lab- grade yikugwiriskira ncito masensa gha fluxgate - ppm-level kugomezgeka, kweni wakudura.
Kasi ni nthowa wuli iyo mungagwiliskira nchito yikuthemba pa fomu. Forklifts ŵakuwona kuti ma amps ghasonosono gha ma amps ghanandi pa nyengo ya kukwezga -BMS yikwenera kugwira ntchito na vingwe ivi kwambura maulendo ghautesi. Magalimoto gha Golf ghakutora sonosono apa kweni ghangakhala kwambura kugwiliskirika nchito kwa myezi yinandi, ntheura kupima mtundu ucoko wa mtundu wa mtundu ukukhumbikwa comene.
