Lithium Battery mapaketi akafanana neinjini anoshaya kuchengetedza; aBMSPasina basa rekuyera ingori muunganidzi wedatha uye haakwanise kutariswa kuratidzwa kwehunyanzvi. Zvese zviri zviviri zvinoshanda uye zvinopfuura zvine mwero chinangwa kubvisa kusawirirana mukati mebhatiri pakiti, asi nheyo dzisiri dzekuita dzakasiyana.
Kujekesa, chinyorwa ichi chinotsanangura chiyero chakatangwa neBSMS kuburikidza neAlgorithms yekuenzanisa, nepo kuyera uko kunoshandisa resitors kuti vasiye simba rinotumidzwa kuyera. Kuenzanisa kunoshanda kunosanganisira kuendesa kwesimba, nepo zvichidaridzira zvine simba zvinosanganisira kusvibiswa kwesimba.
Batter Battery pack Dhizaina Nheyo
- Kubhadharisa kunofanirwa kumisa kana sero rekutanga rikapihwa zvizere.
- Kuregedza kunofanirwa kupera kana chitokisi chekutanga chapera.
- Weakes cell zera nekukurumidza kupfuura maseru akasimba.
- -Iye cell neiyo isina kusimba kubhadharisa ichapedzisira yapera bhatiri pack's kusungirirwa (iyo isina kusimba link).
- Iyo system tembiricha gradient mukati mebhatiri pakiti inoita kuti masero anoshanda paakakwira avhareji ekupisa.
- Pasina kuyera, musiyano weVoltage pakati peiyo isina kusimba uye yakasimba masero inowedzera neyechagedhi imwe neimwe uye discharge kutenderera. Pakupedzisira, sero rimwe rinoswedera kuwanda kwelttage nepo imwe ichisvika madiki voltage, kugadzirisa iyo pack's Capital uye discharge kugona.
Nekuda kwesismatch yemasero nekufamba kwenguva uye akasiyana tembiricha mamiriro kubva kuKuisa, sero kuyera kwakakosha.
Lithium-ion mabhatiri anonyanya kutarisana nemhando mbiri dzeMismatch: Kuchaira Mismatch uye kugona mismatch. Kuchaja mismatch kunoitika kana masero emugodhi mumwe chete akasiyana zvishoma nezvishoma ari mutungamiriri. Kugona kusanganisa kunoitika kana masero ane akasiyana ekutanga masangano anoshandiswa pamwe chete. Kunyangwe masero anowanzoenderana chaizvo kana akagadzirwa akatenderedza nguva imwechete nemaitiro akafanana ekugadzira, mismatches inogona kumuka kubva kumasero ane zvisingazivikanwe zvinyorwa kana zvakakosha kugadzira mutsauko.
Active Balance vs. Passive Balance
1. Chinangwa
Buttery mapaketi ane akawanda akateedzana-masero maseru, izvo zvisingafarire zvakafanana. Kuyera kunozivisa kuti kutsauka kwesero kunochengetwa mukati medzidziso, kuchengeta chengetedzo yakazara uye kudzorwa, nekudaro kudzivirira kukuvara uye nekuwedzera hupenyu hwebhatiri.
2. Dhizaini yekuenzanisa
- Passive Balance: Kazhinji inoburitsa masero akakwira voltage uchishandisa resters, inoshandura simba rakawandisa mukupisa. Iyi nzira inowedzera kubhadharisa nguva yemamwe masero asi ane kuderera kwekubudirira.
- Anoshanda kuyera: maitiro akaomarara anogadzirisa mari mukati memasero panguva yekuchaja uye kubvisa maCocle, kuderedza nguva yekuchaja uye yekuwedzera discharge nguva yekuzorora. Izvo zvinowanzo shandisa pasi pasi mazano ekuenzanisa panguva yekubuda uye pamusoro mazano ekuenzanisa panguva yekuchaja.
- Pros uye Enzaniso Enzanisa: Passive Balance isiriyo uye yakachipa asi isinganyatsoita, sezvazviri simba simba sekupisa uye ranyatsononoka kuyera mhedzisiro. Kubatira kuyera kunoshanda zvakanyanya, kuchinjisa simba pakati pemasero, izvo zvinovandudza zvakazara kushandiswa kwekushandisa uye kuwana zviyero zvakanyanya nekukurumidza. Nekudaro, zvinosanganisira zvivakwa zvakaoma uye mitengo yakakwira, ine matambudziko mukubatanidza aya masisitimu mune zvakatsaurwa.
Mhedziso
Pfungwa yeBS yakatanga kuvandudzwa kunze kwenyika. Pfungwa yekuyera yakazounzwa, pakutanga ichishandisa nzira dzekuramba dzakasangana dzakabatanidzwa muICs. Iyi nzira yave kuparadzaniswa, nemakambani senge ti, maxim, uye mutsara kuburitsa machipisi akadaro, mamwe ekubatanidza madhiraivha ari mumachira.
Kubva pane inopfuura nheyo dzekuenzanisa uye madhiri, kana iyo bhatiri paki ichienzaniswa nebhari, masero akaita sedanda. Masero ane simba rakakwirira masimbi marefu, uye idzo ine simba rakaderera pamapuranga mapfupi. Passive Kuenzanisa "kupfuuridza" mapuranga akareba, anokonzerwa nesimba rakapunzika uye kusakwana. Iyi nzira ine zvisingakwanisi, kusanganisira yakanyanya kupisa kupisa kupaza uye inononoka kuyera mhedzisiro mumapepa makuru ekugona.
Kuita zvinoenderana zvishoma, "anozadza mumapuranga mapfupi," kuendesa simba pfupi kubva pamasero emasimba akanyanya kune akaderera-simba, anokonzerwa nekubudirira kwakanyanya uye anokurumidza kubhadharwa. Nekudaro, inounza kuoma uye kunetsa nyaya, nematambudziko mukugadzira switch matrices uye kudzora kutyaira.
Kupiwa kutengeserana-offs, kupaza mari inokodzera kunogona kunge kwakakodzera masero ane hukama hwakanaka, nepo chiyero chinoshanda chiri chibvumirano chiri chisarudzo chine masero makuru.
