Muchidimbu, kuenzana ndiyo avhareji yemagetsi ekuenzana. Chengetedza voltage yelithium bhatiri packKuenderana. Kuenzanisa kwakakamurwa kuita active balancing uye passive balancing. Saka musiyano uripi pakati peactive balancing ne passive balancing ye lithium battery protection board? Ngatitarisei neHeltec Energy.
Kuenzanisa kwakasimba kwebhodhi rekudzivirira bhatiri re lithium
Kuenzanisa mafambiro emagetsi kunoreva kuti tambo ine voltage yakakwira inowedzera simba kune tambo ine voltage yakaderera, kuitira kuti simba risaparadzwe, voltage yakakwira inogona kudzikiswa, uye voltage yakaderera inogona kuwedzerwa. Rudzi urwu rwemagetsi anomhanya anogona kusarudza saizi yemagetsi ekuenzanisa wega. Chaizvoizvo, 2A inowanzoshandiswa, uye kunewo makuru ane 10A kana kupfuura.
Iye zvino michina yekuenzanisa inoshanda pamusika inoshandisa musimboti wetransformer, ichivimba nemachipisi anodhura evagadziri vemachipisi. Pamusoro pechipisi chekuenzanisa, kunewo zvinhu zvinodhura zveperipheral zvakaita sematransformer, ayo akakura uye anodhura zvakanyanya.
Mhedzisiro yekuenzana kwekushanda iri pachena: kushanda zvakanaka, simba shoma rinoshandurwa uye hariparadzwe muchimiro chekupisa, uye kurasikirwa chete ndiyo coil ye transformer.
Kuenzanisa kwemagetsi kunogona kusarudzwa uye kumhanya kwekuenzanisa kunokurumidza. Kuenzanisa kwemagetsi kwakaoma muchimiro kupfuura kusanganisa kwemagetsi, kunyanya nzira yekushandura. Mutengo weBMS nekushanda kwekuenzanisa kwemagetsi kuchave wakakwira zvakanyanya kupfuura wekuenzanisa kwemagetsi, izvo zvinoderedzawo kusimudzirwa kwekuenzanisa kwemagetsi.BMS.
Kuenzanisa kusingashande kwebhodhi rekudzivirira bhatiri re lithium
Kuenzanisa kusingashande kunowanzoitwa nekuwedzera ma resistors pakuburitsa. Tambo yemagetsi ine simba guru inoburitswa muchimiro chekuparadza kupisa kunzvimbo yakapoteredza, zvichiita kuti resistor itonhore. Dambudziko nderekuti kubuda kwacho kunobva patambo yemagetsi yakaderera, uye pane mukana wekuti pave nenjodzi pakuchaja.
Kuenzanisa kusingashande kunonyanya kushandiswa nekuda kwemutengo wayo wakaderera uye kushanda kwayo kuri nyore; dambudziko rayo nderekuti yakaenzana zvichibva pasimba rakaderera, uye haigone kuwedzera tambo ine voltage shoma, zvichikonzera kurasikirwa kwesimba.
Musiyano uripo pakati pekuyera zvinhu (active balancing) nekuenzanisa zvinhu (passive balancing)
Kuenzanisa kusingashande kwakakodzera kune vane simba diki, vane voltage shomamabhatiri e lithiamu, nepo active balancing yakakodzera kushandiswa kwemagetsi ane simba guru re lithium battery pack.
Matekinoroji anoshandiswa zvakanyanya ekugadzirisa mabhatiri anosanganisira kuchaja bhatiri rinogara richichinja bhatiri, kuchaja bhatiri rinodzima bhatiri, kuchaja bhatiri rinochinja bhatiri, kuchaja bhatiri rinochinja bhatiri, kuchaja bhatiri rinochinja bhatiri, kuchaja bhatiri rinochinja bhatiri, kuchaja bhatiri rinochinja bhatiri, nezvimwewo. Pakuchaja mabhatiri e lithium akatevedzana, bhatiri rega rega rinofanira kuchaja zvakaenzana, zvikasadaro mashandiro nehupenyu hwebhatiri rose zvinokanganiswa panguva yekushandiswa.

Nheyo huru yekusashandisa simba rakawandisa ndeyekuwana simba rakawandisa nekushandisa simba rakawandisa. Kazhinji, simba rakawandisa riri mubhatiri rinoshandisa simba rakawandisa rinoshandurwa kuita kupisa kuburikidza ne resistor, kuitira kuti voltage yebhatiri irambe yakafanana. Chakanakira ndechekuti dunhu rekusashandisa simba rakaderera uye mutengo wekugadzira nekushandisa wakaderera. Uye tekinoroji yekusashandisa simba rakura uye yakashandiswa zvakanyanya muzvinhu zvakawanda zvakachipa uye zvidiki.mapaketi emabhatiri.
Dambudziko nderekuti pane kurasikirwa kukuru kwesimba nekuda kwekushandurwa kwesimba remagetsi kuita kupisa kuburikidza nekuramba. Kushanda zvishoma, kunyanya mumapaketi emabhatiri ane simba guru, marara esimba ari pachena, uye haana kukodzera kushandiswa kwemabhatiri makuru, anoshanda zvakanyanya. Uye nekuda kwekuti simba remagetsi rinoshandurwa kuita kupisa, rinogona kukonzera kuti paki yebhatiri iwedzere kupisa, zvichikanganisa kuchengetedzeka uye hupenyu hwehurongwa hwese.
Kuenzanisa kwakasimba kunoita kuti pave nekukwanisa kuenzanisa simba remagetsi rakawandisa kubva kumabhatiri ane voltage yakakwira kuenda kumabhatiri ane voltage yakaderera. Nzira iyi inowanzo gadzirisa kugoverwa kwesimba pakati pemabhatiri kuburikidza nekuchinjana magetsi, ma converter e buck-boost kana zvimwe zvikamu zvemagetsi. Chakanakira ndechekuti simba hariparadzwe, asi rinoenzaniswa nekutamiswa, saka hapana kurasikirwa nekupisa, uye kushanda kwacho kunowanzo kuve kwakakwira (kusvika 95% kana kupfuura).
Kuchengetedza simba: Sezvo pasina marara esimba, yakakodzera kushandiswa pakugadzira simba guru uye kushanda nesimba.bhatiri re lithiamumasisitimu uye inogona kuwedzera hupenyu hwebasa repaketi yebhatiri. Inoshanda kumapaketi emabhatiri makuru: Kuenzanisa kwakakodzera kwakanyanya kukodzera mapaketi emabhatiri ane simba guru, kunyanya mumamiriro ezvinhu akadai semotokari dzemagetsi uye masisitimu ekuchengetera simba, uye inogona kuvandudza zvakanyanya kushanda zvakanaka kwesisitimu uye kutsungirira kwayo.
Dambudziko nderekuti dhizaini nekushandiswa kwe active balancing zvakaoma, kazhinji zvinoda zvikamu zvemagetsi zvakawanda, saka mutengo wacho wakakwira. Kuoma kwehunyanzvi: Kudzora kwakaringana uye dhizaini yedunhu zvinodiwa, izvo zvakaoma uye zvinogona kuwedzera kuoma kwekugadzira nekugadzirisa.
Mhedziso
Kana iri sisitimu yakaderera, diki kana kuti ine zvinodiwa zvishoma zvekuyera, passive balancing inogona kusarudzwa; kune masisitimu emabhatiri anoda manejimendi yesimba inoshanda zvakanaka, kugona kukuru kana kushanda kwepamusoro, active balancing isarudzo iri nani.
Heltec Energy ikambani inogadzira nekugadzira michina yekuongorora nekugadzirisa mabhatiri inoshanda zvakanyanya, uye inopa mhinduro dzekugadzira mabhatiri emusana, kugadzira mapaketi, uye kugadzirisa mabhatiri ekare emagetsi.mabhatiri e lithiamu.
Heltec Energy yagara ichisimbirira pakugadzira zvinhu zvitsva yakazvimirira, nechinangwa chikuru chekupa zvigadzirwa zvakavimbika uye zvinodhura zvishoma muindasitiri yemabhatiri e lithium, uye nepfungwa yebasa rekuti "kutanga mutengi, kunaka kwemhando yepamusoro" kuti vagadzire kukosha kune vatengi. Munguva yekugadzirwa kwayo, kambani ine timu yemainjiniya vakuru muindasitiri, izvo zvinovimbisa kufambira mberi uye kushanda kwezvigadzirwa zvayo.
Kana muine mibvunzo kana kuti muchida kuziva zvakawanda, musazeza kupindurataura nesu.
