Mukutaura kwakapfava, kuenzanisa ndiyo avhareji yekuyera voltage. Chengetedza voltage yelithium bhatiri packanowirirana. Kuenzanisa kunopatsanurwa kuita kuenzanisa kunoshanda uye kungoita kuenzanisa. Saka ndeupi musiyano uripo pakati peanoshanda kuenzanisa uye passive kuenzanisa yelithium bhatiri kuchengetedza bhodhi? Ngatitarisei neHeltec Energy.
Kushanda kuenzanisa kwe lithium bhatiri kuchengetedza bhodhi
Active balancing ndeyekuti tambo ine high voltage inowedzera simba kune tambo ine yakaderera voltage, kuitira kuti simba risaparadzwe, high voltage inogona kudzikiswa, uye low voltage inogona kuwedzerwa. Iyi mhando yeanoshanda kuenzanisa ikozvino inogona kusarudza iyo yakaenzana saizi yazvino uri wega. Chaizvoizvo, 2A inowanzoshandiswa, uye kune zvakare makuru ane 10A kana kunyange akakwirira.
Iye zvino iyo inoshanda yekuenzanisa midziyo pamusika inonyanya kushandisa iyo transformer musimboti, ichivimba nemachipisi anodhura evagadziri vechip. Pamusoro peiyo balancing chip, kune zvakare inodhura peripheral components se transformers, iyo yakakura muhukuru uye yakakwirira mumutengo.
Mhedzisiro yekushanda kwekuenzanisa inonyatsojeka: kushanda kwepamusoro kwekushanda, simba shoma rinoshandurwa uye harina kuparara nenzira yekupisa, uye kurasikirwa chete ndiyo coil ye transformer.
Ikozvino yekuenzanisa inogona kusarudzwa uye kukurumidza kwekuenzanisa inokurumidza. Active balancing yakanyanya kuoma muchimiro pane passive balancing, kunyanya iyo transformer nzira. Mutengo weBMS ine inoshanda kuenzanisa basa ichave yakanyanya kukwirira kupfuura iyo yekungoita kuenzanisa, iyo zvakare inoganhurira kusimudzirwa kwekuita kuenzanisa.BMS.
Passive balancing ye lithium bhatiri kuchengetedza bhodhi
Passive balancing inonyanya kuitwa nekuwedzera resistors kuburitsa. Iyo yakakwira-voltage tambo yemasero inoburitswa nenzira yekupisa kupisa kunzvimbo yakapoteredza, ichiwana mhedzisiro yekutonhodza resistor. Izvo zvakashata ndezvekuti kubuda kunobva pane yakaderera voltage tambo, uye pane mukana wengozi paunenge uchichaja.
Passive balancing inonyanya kushandiswa nekuda kwemutengo wayo wakaderera uye nyore kushanda musimboti; kuipa kwayo ndeyokuti yakaenzana inobva kune simba rakaderera, uye haigoni kuwedzera tambo yakaderera-voltage, zvichiita kuti simba riparare.
Musiyano uripo pakati pekuita kuenzanisa uye kungoita kuenzanisa
Passive balancing yakakodzera kudiki-simba, yakaderera-voltagelithium mabhatiri, nepo kuenzanisa kuenzanisa kwakakodzera kune yakakwirira-voltage, yakakura-simba simba lithium battery pack applications.
Michina yekuchaja inowanzoshandiswa inosanganisira shunt resistor balancing charging, on-off shunt resistor balancing charging, avhareji yebhatiri voltage balancing kuchaja, chinja capacitor balancing kuchaja, buck converter balancing kuchaja, inductor balancing kuchaja, nezvimwewo. Paunenge uchichaja boka re lithium akatevedzana, bhatiri rega rega rinofanira kuchajwa zvakaenzana, kana zvisina kudaro kuita uye hupenyu yeboka rose rebhatiri ichakanganiswa panguva yekushandiswa.

Nheyo yekutanga yekuisa kuenzanisa ndeyekuwana iyo balancing mhedzisiro nekutambisa simba rakawandisa. Kazhinji, iyo yakawandisa simba mune yakawandisa bhatiri paki inoshandurwa kuita kupisa kuburikidza neinopikisa, kuitira kuti bhatiri voltage irambe ichienderana. Chakanakira ndechekuti passive balancing wedunhu iri nyore uye dhizaini nekuita mutengo wakaderera. Uye iyo passive balancing tekinoroji yakakura kwazvo uye yakashandiswa zvakanyanya mumutengo wakaderera uye mudikibhatiri packs.
Izvo zvisingabatsiri ndezvokuti kune simba guru rekurasikirwa nekuda kwekushandurwa kwesimba remagetsi mukupisa kuburikidza nekupikisa. Kuderera kwakaderera, kunyanya muhombe-yakakura bhatiri packs, simba remarara rinonyanya kuoneka, uye harina kukodzera hukuru-hukuru, hukuru hwekushanda kwebhatiri. Uye nekuti simba remagetsi rinoshandurwa kuita kupisa, rinogona kuita kuti bhatiri paki riwedzere kupisa, zvichikanganisa kuchengetedza uye hupenyu hwese system.
Active balancing inowana kuenzanisa nekufambisa yakawandisa simba remagetsi kubva kumabhatiri ane voltage yakakwira kuenda kumabhatiri ane voltage yakaderera. Iyi nzira inowanzo gadzirisa kugovera kwemagetsi pakati pemabhatiri kuburikidza nekuchinja magetsi emagetsi, buck-boost converters kana zvimwe zvinhu zvemagetsi. Kubatsira kwepamusoro-soro: simba harina kuparara, asi rakaenzana nekufambisa, saka hapana kurasikirwa kwekupisa, uye kubudirira kunowanzo kukwirira (kusvika 95% kana kupfuura).
Kuchengetedza magetsi: Sezvo pasina simba remarara, rakakodzera hukuru-hukuru, kushanda kwepamusorolithium bhatirimasystem uye anogona kuwedzera hupenyu hwesevhisi yebhatiri pack. Inoshanda kune yakakura bhatiri mapaketi: Kushanda kuenzanisa kunonyanya kukodzera kune yakakura-inotakura bhatiri mapaketi, kunyanya mumamiriro ezvinhu akadai semotokari dzemagetsi uye masisitimu ekuchengetedza simba, uye inogona kuvandudza zvakanyanya mashandiro ehurongwa uye kutsungirira.
Izvo zvisingabatsiri ndezvokuti kugadzira uye kushandiswa kwekushanda kwekuenzanisa kunenge kwakaoma, kazhinji kunoda zvimwe zvikamu zvemagetsi, saka mari yacho yakakwirira. Kuoma kwehunyanzvi: Kunyatso kudzora uye dhizaini dhizaini inodiwa, iyo yakaoma uye inogona kuwedzera kuoma kwekusimudzira nekugadzirisa.
Mhedziso
Kana iri yakaderera-mutengo, diki sisitimu kana application ine yakaderera zvinodiwa zvekuenzanisa, passive balancing inogona kusarudzwa; kune mabhatiri masisitimu ayo anoda kushanda nesimba manejimendi, hukuru hukuru kana hukuru hwekuita, kushingaira kuenzanisa isarudzo iri nani.
Heltec Energy ikambani inogadzira uye inogadzira yakakwirira-inoshanda bhatiri yekuyedza nekugadzirisa michina, uye inopa mhinduro dzekupedzisira-kumagumo kugadzira, kugadzira gungano repaki, uye kugadzirisa bhatiri rekare.lithium mabhatiri.
Heltec Energy yakagara ichisimbirira pazvitsva zvakasununguka, nechinangwa chikuru chekupa zvigadzirwa zvakavimbika uye zvinodhura zvakanyanya muindasitiri yebhatiri yelithium, uye nepfungwa yebasa re "mutengi kutanga, kunaka kwemhando" kugadzira kukosha kune vatengi. Munguva yekuvandudzwa kwayo, kambani ine timu yevakuru mainjiniya muindasitiri, iyo inovimbisa zvinobudirira kufambira mberi uye kushanda kwezvigadzirwa zvayo.
Kana uine chero mibvunzo kana uchida kudzidza zvakawanda, ndapota usazezasvika kwatiri.
