1.Passive kuenzana

Passive kuenzana kazhinji inoburitsa iyo yakakwira voltage lithium-ion bhatiri kuburikidza neresist discharge, kuburitsa simba nenzira yekupisa kutenga imwe nguva yekuchaja kune mamwe mabhatiri. Nenzira iyi simba rehurongwa hwese rinoganhurwa nebhatiri rine hushoma huwandu. Panguva yekuchaja, mabhatiri e-lithium-ion anowanzo kuve necharge limit yekudzivirira voltage value, kana tambo yemabhatiri ichisvika pakukosha kwevoltage iyi, lithium-ion bhatiri rekuchengetedza bhodhi rinocheka dunhu rekuchaja uye kumisa kuchaja. Kana iyo yekuchaja voltage ichipfuura kukosha uku, iyo inowanzozivikanwa seyakawandisa, iyo lithium-ion bhatiri inogona kupisa kana kuputika. Naizvozvo, lithium-ion bhatiri dziviriro mapaneru anowanzo kuve akashongedzerwa nekudzivirira kwakawandisa kudzivirira bhatiri kuti risakwidzwe.

Mukana we passive equalization ndiyo yakaderera mutengo uye nyore redunhu dhizaini; uye iyo yakashata ndeyekuti iyo shoma bhatiri residual inoshandiswa seyero yekuenzana, saka hazvibviri kuwedzera huwandu hwebhatiri nekusara kushoma, uye 100% yesimba rakaenzana rinoraswa nenzira yekupisa.

2. Active kuenzana

Active kuenzana ndiko kuenzana nekufambisa kwesimba nekushanda kwakanyanya uye kurasikirwa kwakaderera. Iyo nzira inosiyana kubva kune mugadziri kune mugadziri uye equalization ikozvino inosiyana kubva pa1 kusvika 10? A. Mazhinji eanoshanda eequalization matekinoroji aripo pamusika haana kukura, zvichitungamira mukubuda-kuburitsa uye nekukasira kuora kwebhatiri. Mazhinji eanoshanda ekuenzanisa pamusika anoshandisa iyo musimboti wekushanduka kwemagetsi, ichitsamira pamachipisi anodhura evagadziri vechip. Uye nenzira iyi, mukuwedzera kune yakaenzana chip, asiwo inodhura shandurudzo uye zvimwe zvikamu zveperipheral, zvakakura uye zvinodhura.

Kubatsira kwekushanda kuenzana kwakajeka: kushanda kwepamusoro, simba rinotamiswa, kurasikirwa ndiko chete kushanduka kwekoiri kurasikirwa, kuverenga kwechikamu chiduku; kuenzana ikozvino inogona kugadzirwa kusvika mashoma amps kana kunyange 10A nhanho, iyo yakaenzana mhedzisiro inokurumidza. Pasinei nemabhenefiti aya, kushingaira kuenzana kunounzawo matambudziko matsva. Kutanga, chimiro chakaoma, kunyanya nzira ye transformer. Maitiro ekugadzira iyo switching matrix kune gumi nemaviri kana kunyange mazana etambo dzebhatiri, uye maitiro ekudzora mutyairi, ese misoro. Ikozvino mutengo weBMS ine inoshanda yakaenzana basa ichave yakanyanya kukwirira kupfuura iyo yekusaenzana, iyo inomisawo kukwidziridzwa kweiyo inoshanda yakaenzana BMS zvakanyanya kana zvishoma.

Passive equalization inokodzera diki-inokwana, yakaderera-yakatevedzana lithium-ion bhatiri pack application, nepo inoshanda yakaenzana inokodzera yakakwirira-yakatevedzana, yakakwirira-simba simba lithium-ion bhatiri pack application. Kune BMS, kunze kwebasa rekuenzanisa rakakosha zvakanyanya, nzira yekuenzanisa kumashure ndiyo inonyanya kukosha.

Lithium-ion bhatiri kuchengetedza bhodhi kuenzana nheyo

Inowanzo shandiswa equalization kuchaja nzira dzinosanganisira kugara shunt resistor equalization kuchaja, on-off shunt resistor equalization charging, avhareji cell voltage equalization kuchaja, switched capacitor equalization charging, buck converter equalization charging, inductor equalization charging, etc. Paunenge uchichaja lithium-ion mabhatiri munhevedzano dzakatevedzana. mumapoka, bhatiri rimwe nerimwe rinofanira kuvimbiswa kubhadharwa zvakaenzana, kana zvisina kudaro kushanda uye hupenyu hwebhatiri rose huchakanganiswa panguva yekushandiswa.
