Lithium bhatiri mapaketi akafanana neinjini dzinoshaya kugadzirisa; aBMSpasina basa rekuenzanisa rinongova muunganidzi wedata uye haigone kutorwa sehurongwa hwekutarisira. Ose ari maviri anoshanda uye asingaiti kuenzanisa anovavarira kubvisa kusawirirana mukati mebhatiri pack, asi maitiro avo ekushandisa akasiyana zvakanyanya.
Kuti zvive pachena, chinyorwa ichi chinotsanangura kuyera kwatangwa neBMS kuburikidza nemaalgorithms seanoshanda kuenzanisa, ukuwo kuenzanisa kunoshandisa zvinopikisa kuparadza simba kunonzi passive balancing. Active balancing inosanganisira kufambisa simba, nepo passive balancing inosanganisira kupera simba.
Basic Battery Pack Dhizaini Mitemo
- Kuchaja kunofanira kumira kana sero rekutanga razara.
- Kuburitsa kunofanira kupera kana sero rekutanga rapera.
- Masero asina simba anokura nekukurumidza kupfuura maseru ane simba.
- -iye sero nechaji isina kusimba inozopedzisira yadzikamisa bhatiri paki's inogona kushandiswa (iyo isina simba link).
- Iyo tembiricha tembiricha gradient mukati mebhatiri pack inoita kuti maseru anoshanda paavhareji tembiricha ashaye simba.
- Pasina kuenzanisa, mutsauko wevoltage pakati peasina kusimba uye akasimba maseru anowedzera nechaji yega yega uye kutenderera kutenderera. Pakupedzisira, sero rimwe rinosvika pamhepo yakakura apo imwe ichiswedera padiki voltage, zvichikanganisa kubhadharisa kwepakeji uye kugona kubuda.
Nekuda kwekusawirirana kwemaseru nekufamba kwenguva uye kusiyanisa tembiricha mamiriro kubva pakuiswa, sero kuenzanisa kwakakosha.
Lithium-ion mabhatiri anonyanya kutarisana nemhando mbiri dzekusawirirana: kuchaja kusawirirana uye kugona kusawirirana. Kuchaja kusapindirana kunoitika kana maseru ehumwe simba zvishoma nezvishoma achisiyana mukutarisira. Kusapindirana kwehunyanzvi kunoitika kana maseru ane hunyanzvi hwekutanga akashandiswa pamwechete. Kunyangwe maseru achiwanzo kuenderana kana akagadzirwa panguva imwe chete aine maitiro ekugadzira akafanana, kusawirirana kunogona kubuda kubva kumaseru ane asingazivikanwe masosi kana yakakosha misiyano yekugadzira.
Active Balancing vs. Passive Bancing
1. Chinangwa
Mabhatiri mapegi ane akawanda akatevedzana-akabatana maseru, ayo asingaite kunge akafanana. Bancing inova nechokwadi chekuti kutsauswa kwesero voltage kunochengetwa mukati mezvikamu zvinotarisirwa, kuchengetedza kushandiswa kwese uye kudzoreka, nekudaro kudzivirira kukuvadzwa uye kuwedzera hupenyu hwebhatiri.
2. Dhizaini Kuenzanisa
- Passive Bancing: Kazhinji inoburitsa masero emagetsi epamusoro achishandisa zvinopikisa, achishandura simba rakawandisa kuita kupisa. Iyi nzira inowedzera nguva yekuchaja kune mamwe maseru asi ine kushomeka kwekuita.
- Active Balancing: Nzira yakaoma kunzwisisa iyo inogoverazve kuchaja mukati memasero panguva yekuchaja uye kuburitsa, kuderedza nguva yekuchaja uye kuwedzera nguva yekubuda. Inowanzo shandisa nzira dzekuyera dzepasi panguva yekuburitsa uye nzira dzepamusoro dzekuenzanisa panguva yekuchaja.
- Pros uye Cons Kuenzanisa: Passive balancing iri nyore uye yakachipa asi isinganyanyi kushanda, sezvo ichipedza simba sekupisa uye ine inononoka kuenzanisa mhedzisiro. Active balancing inoshanda zvakanyanya, kuendesa simba pakati pemaseru, izvo zvinovandudza kushandiswa kwese kwese uye kuzadzisa chiyero nekukurumidza. Nekudaro, zvinosanganisira zvimiro zvakaoma uye mitengo yakakwira, nematambudziko mukubatanidza masisitimu aya mumaIC akazvipira.
Mhedziso
Iyo pfungwa yeBMS yakatanga kugadzirwa kunze kwenyika, neyekutanga IC magadzirirwo akatarisana nemagetsi uye tembiricha yekuona. Pfungwa yekuenzanisa yakazounzwa, pakutanga vachishandisa nzira dzekudzivirira dzakabatanidzwa muICs. Iyi nzira yave kupararira, nemakambani akaita seTI, MAXIM, uye LINEAR achigadzira machipisi akadaro, mamwe achibatanidza madhiraivha ekuchinja mumachipisi.
Kubva pane passive balancing misimboti uye madhayagiramu, kana bhatiri paki ichifananidzwa nedhiramu, maseru akafanana nematanda. Masero ane simba rakakwirira mapuranga akareba, uye ayo ane simba shoma ndiwo mapuranga mapfupi. Passive balancing chete "inopfupisa" mapuranga akareba, zvichikonzera kutambisa simba uye kusashanda. Iyi nzira ine painogumira, kusanganisira kwakakosha kupisa kupisa uye kunonoka kuenzanisa mhedzisiro mumahombe ekugona mapaketi.
Active balancing, nekusiyana, "inozadza mapuranga mapfupi," kuendesa simba kubva kune akakwirira-esimba maseru kuenda kune yakaderera-simba, zvichikonzera kushanda kwepamusoro uye nekukurumidza kuenzana kuwana. Nekudaro, inounza kuoma uye mutengo nyaya, nematambudziko mukugadzira switch matrices uye kudzora madhiraivha.
Tichifunga nezvekutengeserana-offs, passive balancing inogona kunge yakakodzera kune maseru ane yakanaka kuenderana, nepo inoshanda kuenzanisa inodiwa kune maseru ane mutsauko mukuru.
