Pfungwa yekuenzanisa maseroZvingangodaro zvinozivikanwa nevakawanda vedu. Izvi zvinonyanya kuitika nekuti kuenderana kwemasero pari zvino hakuna kukwana, uye kuenzana kunobatsira kuvandudza izvi. Kungofanana nekusagona kuwana mashizha maviri akafanana pasi rose, haugonewo kuwana masero maviri akafanana. Saka, pakupedzisira, kuenzana ndekugadzirisa zvikanganiso zvemasero, zvichishanda senzira yekutsiva.
Ndezvipi Zvinoratidza Kusawirirana Kwemasero?
Pane zvinhu zvikuru zvina: SOC (State of Charge), resistance yemukati, self-discharge current, uye capacity. Zvisinei, kuenzana hakugone kugadzirisa zvachose kusawirirana uku kunana. Kuenzana kunogona kungotsiva misiyano yeSOC, zvichigadzirisa kusawirirana kweself-discharge. Asi pakuenzana kwemukati nekukwanisa, kuenzana hakuna simba.
Kusawirirana kwemasero kunokonzerwa sei?
Pane zvikonzero zviviri zvikuru: chimwe kusawirirana kunokonzerwa nekugadzirwa nekugadzirwa kwemasero, uye chimwe kusawirirana kunokonzerwa nenzvimbo inoshandiswa nemasero. Kusawirirana kwekugadzirwa kunobva pazvinhu zvakaita sematekiniki ekugadzirisa nezvinhu, izvo zviri nyore kunzwisisa nyaya yakaoma zvikuru. Kusawirirana kwezvakatipoteredza kuri nyore kunzwisisa, sezvo nzvimbo yesero rega rega muPACK yakasiyana, zvichikonzera kusiyana kwezvakatipoteredza senge shanduko diki mukupisa. Nekufamba kwenguva, misiyano iyi inoungana, zvichikonzera kusawirirana kwemasero.
Kuenzanisa Kunoshanda Sei?
Sezvambotaurwa, kuenzana kunoshandiswa kubvisa kusiyana kweSOC pakati pemasero. Zvakanaka, zvinoita kuti SOC yesero rega rega ive yakafanana, zvichibvumira masero ese kusvika pamiganhu yepamusoro nepasi yekuchaja nekuburitsa panguva imwe chete, nokudaro zvichiwedzera kugona kwekushandisa kwebhatiri. Pane mamiriro maviri emusiyano weSOC: imwe ndeyekuti kana kugona kwemasero kwakafanana asi maSOC akasiyana; imwe ndeyekuti kana kugona kwemasero nemaSOC ese akasiyana.
Chiitiko chekutanga (kuruboshwe mumufananidzo uri pazasi) chinoratidza masero ane simba rakafanana asi maSOC akasiyana. Sero rine maSOC madiki rinotanga rasvika pamuganho wekuburitsa (tichifunga kuti 25% SOC ndiyo muganho wakaderera), nepo sero rine maSOC makuru rinotanga rasvika pamuganho wekuchaja. Nekuenzanisa, masero ese anochengetedza maSOC akafanana panguva yekuchaja nekuburitsa.
Chiitiko chechipiri (chechipiri kubva kuruboshwe mumufananidzo uri pazasi) chinosanganisira masero ane kugona kwakasiyana uye maSOC. Pano, sero rine kugona kudiki rinotanga kubhadharisa uye kuburitsa. Nekuenzanisa, masero ese anochengetedza SOC imwechete panguva yekuchaja nekuburitsa.
Kukosha Kwekuenzanisa
Kuenzanisa ibasa rakakosha kumasero aripo. Kune mhando mbiri dzekuenzanisa:kuenzanisa kunoshandauyekuenzana kusingashande. Kuenzanisa kusingashande kunoshandisa ma resistors pakuburitsa simba, nepo active balancing ichisanganisira kufamba kwechaji pakati pemasero. Pane gakava pamusoro pemashoko aya, asi hatizopindi mune izvozvo. Passive balancing inonyanya kushandiswa mukuita, nepo active balancing isingawanzoitiki.
Kusarudza Kuenzanisa Kwemvura yeBMS
Kuti pave nekuenzana kwemagetsi, simba remagetsi rinofanira kusarudzwa sei? Zvakanaka, rinofanira kunge rakakura sezvinobvira, asi zvinhu zvakaita semutengo, kupisa, nenzvimbo zvinoda kubvumirana.
Usati wasarudza balancing current, zvakakosha kunzwisisa kana mutsauko weSOC uri nekuda kwechiitiko chekutanga kana chechipiri. Kazhinji, uri pedyo nechiitiko chekutanga: masero anotanga aine simba rakafanana uye SOC, asi sezvaanoshandiswa, kunyanya nekuda kwemusiyano wekubuda kwesimba, SOC yesero rega rega inova yakasiyana zvishoma nezvishoma. Nokudaro, kugona kwekuenzanisa kunofanira kubvisa kukanganisa kwekusiyana kwekubuda kwesimba.
Dai masero ese aive neanozviburitsa akafanana, kuenzana kwaisazodiwa. Asi kana paine musiyano mu self-discharge current, misiyano yeSOC inomuka, uye kuenzana kunodiwa kuti izvi zvikwanisike. Pamusoro pezvo, sezvo avhareji yenguva yekuverenga zuva nezuva yakaganhurirwa nepo self-discharge ichiramba ichienderera mberi zuva nezuva, nguva inofanirawo kufungwa nezvayo.
