Thebhatiri systemndiyo musimboti weiyo yese simba rekuchengetedza sisitimu, ine mazana e cylindrical maseru kanaprismatic maseromunhevedzano uye zvakafanana.Kusawirirana kwemabhatiri ekuchengetedza simba kunonyanya kureva kusaenderana kwezviyero zvakadai sebhatiri simba, kuramba mukati, uye tembiricha.Kana mabhatiri ane kusawirirana akashandiswa munhevedzano uye akafanana, anotevera matambudziko achaitika:

1. Kurasikirwa kwesimba rinowanikwa

Musimba rekuchengetedza simba, masero mamwechete akabatanidzwa munhevedzano uye akafanana kuti agadzire bhokisi rebhatiri, mabhokisi ebhatiri akabatanidzwa munhevedzano uye akafanana kuti aumbe bhatiri cluster, uye akawanda mabhatiri masumbu akabatana zvakananga kune imwechete DC busbar yakafanana. .Zvikonzero zvekusawirirana kwebhatiri zvinotungamira mukurasikirwa kwesimba rinoshandiswa zvinosanganisira kutevedzana kusawirirana uye kuenderana kwakafanana.

•Battery series kusawirirana kurasikirwa
Zvinoenderana neiyo barrel musimboti, huwandu hwakateedzana hwebhatiri system hunoenderana nebhatiri rimwechete rine diki diki.Nekuda kwekusawirirana kwebhatiri rimwe chete pacharo, mutsauko wekushisa uye zvimwe zvisingaenderani, iyo inogona kushandiswa yebhatiri imwe neimwe ichave yakasiyana.Bhatiri rimwechete riine hudiki hudiki rinochajiwa zvakazara kana richichaja uye rinodururwa pakuburitsa, izvo zvinotadzisa kuchaja kwemamwe mabhatiri mubhatiri system.Kuburitsa simba, zvichikonzera kuderera kwehuwandu huripo hwebhatiri system.Pasina hutungamiri hunobudirira huripo, nekuwedzera kwenguva yekushanda, kuderedzwa uye kusiyanisa kwehuwandu hwebheteri huchawedzerwa, uye huwandu huripo hwebhatiri system huchawedzera kukurumidza kuderera.

•Battery cluster parallel inconsistency kurasikirwa

Kana masumbu ebhatiri akabatana zvakananga mukufanana, pachava nekutenderera kwazvino chiitiko mushure mekuchaja uye kuburitsa, uye mavolti ega ega bhatiri cluster achamanikidzwa kuenzana.Kusagutsikana uye kuyerera kusingapere kunokonzera kurasikirwa kwebhatiri uye kukwira kwekushisa, kukurumidza kuora kwebhatiri, uye kuderedza huwandu huripo hwebhatiri system.

Mukuwedzera, nekuda kwekupikisa kuduku kwemukati kwebheteri, kunyange kana kusiyana kwevheji pakati pemasumbu anokonzerwa nekusawirirana kunongova mashoma volts, iyo isina kuenzana ikozvino pakati pemasumbu ichave yakakura.Sezvinoratidzwa mune yakayerwa data yechiteshi chemagetsi patafura iri pazasi, mutsauko wekuchaja ikozvino unosvika 75A (Kuenzaniswa neavhareji yetioretical, kutsauka kuri 42%), uye kutsauka kwazvino kunozotungamira mukuwedzeredza uye kuwedzeredza mune mamwe masumbu ebhatiri. ;zvichakanganisa zvakanyanya kuchaja nekuburitsa mashandiro, hupenyu hwebhatiri, uye zvinototungamira kunjodzi dzakakomba dzekuchengetedza.

2.Kukurumidzira kusiyanisa uye kupfupika kwehupenyu hwemasero ega anokonzerwa nekusagadzikana kwekushisa

Tembiricha ndiyo inonyanya kukosha inokanganisa hupenyu hwesimba rekuchengetedza system.Kana kupisa kwemukati kwesimba rekuchengetedza simba kunowedzera ne15 ° C, hupenyu hwehurongwa huchapfupiswa nehafu.Iyo lithium bhatiri ichaunza kupisa kwakawanda panguva yekuchaja uye yekuburitsa, uye kusiyanisa kwekushisa kwebhatiri rimwe chete kuchawedzera kusawirirana kwekupikiswa kwemukati uye kugona, izvo zvinozotungamira mukusiyana kwakakura kwebhatiri rimwe chete, kupfupisa kutenderera. hupenyu hwebhatiri system, uye kunyange kukonzera njodzi dzekuchengetedza.

Nzira yekugadzirisa sei kusawirirana kwemabhatiri ekuchengetedza simba?

Kusawirirana kwebhatiri ndicho chinokonzera matambudziko mazhinji mumasisitimu ekuchengetedza simba aripo.Kunyange zvazvo kusagadzikana kwebheteri kwakaoma kubvisa nekuda kwemakemikari maitiro emabhatiri uye kukanganisa kwenzvimbo yekushandiswa, teknolojia yedhijitari, teknolojia yemagetsi emagetsi uye teknolojia yekuchengetedza simba inogona kubatanidzwa kushandisa magetsi.Kudzora kwehunyanzvi hwemagetsi kunoderedza kukanganisa kwe lithium bhatiri kusawirirana, izvo zvinogona kuwedzera zvakanyanya kugona kushandiswa kwesimba rekuchengetedza masisitimu uye kugadzirisa kuchengetedza system.

• Active balancing tekinoroji inotarisisa voltage uye tembiricha yebhatiri rimwe nerimwe munguva chaiyo, zvakanyanya kubvisa kusawirirana kwebhatiri mutsara wekubatanidza, uye inowedzera huwandu huripo hwesimba rekuchengetedza system nekupfuura 20% muhupenyu hwese.

• Mukugadzirwa kwemagetsi kwesimba rekuchengetedza simba, kubhadharisa uye kubuda kwekutonga kweboka rimwe nerimwe remabhatiri kunoitwa zvakasiyana, uye masumbu ebheteri haana kubatanidzwa mukufanana, izvo zvinodzivirira dambudziko rekutenderera rinokonzerwa nekubatana kwakafanana kweDC, uye zvinobudirira inovandudza huripo huripo hwehurongwa.

• Kunyatso kudzora tembiricha kuwedzera hupenyu hwesimba rekuchengetedza system

Kupisa kwesero rimwe nerimwe kunounganidzwa uye kutariswa munguva chaiyo.Kuburikidza neatatu-nhanho yeCFD yekupisa yekufananidza uye yakawanda yedata rekuyedza, dhizaini yekupisa yebhatiri system inogadziriswa, kuitira kuti musiyano mukuru wetembiricha pakati pemasero ega ebhatiri system isingasviki 5 ° C, uye dambudziko re kusiyanisa kwesero rimwe kunokonzerwa nekusagadzikana kwekushisa kunogadziriswa.

Unoda kugadzira yakagadziridzwa lithium bhatiri zvinoenderana nechakakosha chinodiwa, unogamuchirwa kubvunza LIAO timu kuti uwane rumwe ruzivo.
