Chii Chinoitika Kana BMS Yakundikana?

A Battery Management System (BMS) inoita basa rakakosha mukuona kushanda kwakachengeteka uye kwakanaka kwemabhatiri e-lithium-ion, anosanganisira LFP uye ternary lithium mabhatiri (NCM/NCA). Chinangwa chayo chikuru ndechekutarisa uye kudzora akasiyana bhatiri paramita, senge voltage, tembiricha, uye zvazvino, kuve nechokwadi chekuti bhatiri rinoshanda mukati memiganhu yakachengeteka. Iyo BMS inodzivirirawo bhatiri kuti risachajirwe zvakanyanya, kuregedzerwa, kana kushanda kunze kweiyo tembiricha yakakwana. Mumabhatiri mapaketi ane akawanda akateedzana maseru (bhatiri tambo), iyo BMS inodzora kuenzanirana kwesero rega. Kana iyo BMS ikakundikana, bhatiri rinosara panjodzi, uye mhedzisiro inogona kuve yakaoma.

1. Kuwedzeresa kana kuburitsa zvakanyanya

Rimwe remabasa akanyanya kuomesesa eBMS nderekudzivirira bhatiri kuti risachajirwe kana kubuditswa. Kuchaja zvakanyanya kune njodzi kumabhatiri ane-high-energy-density senge ternary lithium (NCM/NCA) nekuda kwekusagadzikana kwavo kwekupisa kwemhepo. Izvi zvinoitika kana simba rebhatiri richipfuura miganhu yakachengeteka, richigadzira kupisa kwakanyanya, izvo zvinogona kukonzera kuputika kana moto. Kuwedzeredza-kuburitsa, kune rumwe rutivi, kunogona kukonzera kukuvadzwa zvachose kumaseru, kunyanya mumabhatiri eLFP, anogona kurasikirwa nekugona uye kuratidza kusashanda zvakanaka mushure mekubuda kwakadzika. Mumhando mbiri idzi, kutadza kweBMS kudzora voltage panguva yekuchaja uye kuburitsa kunogona kukonzera kukuvara kusingadzoreki kune bhatiri pack.

2. Overheating uye Thermal Runaway

Ternary lithium mabhatiri (NCM/NCA) anonyanya kunzwira tembiricha yakakwira, zvakanyanya kupfuura mabhatiri eLFP, anozivikanwa nekugadzikana kwekupisa. Zvisinei, marudzi ose ari maviri anoda kungwarira kutarisira tembiricha. BMS inoshanda inotarisisa tembiricha yebhatiri, nekuona kuti inogara mukati menzvimbo yakachengeteka. Kana iyo BMS ikakundikana, kupisa kwakanyanya kunogona kuitika, zvichikonzera chiitiko chine njodzi chinodaidzwa kuti thermal runaway. Mune bhatiri pack inoumbwa neakawanda akateedzana maseru (bhatiri tambo), kupisa kunotiza kunogona kukurumidza kupararira kubva kune rimwe sero kuenda kune rinotevera, zvichikonzera kutadza kunotyisa. Kune akakwira-voltage maapplication senge mota dzemagetsi, njodzi iyi inokwidziridzwa nekuti kuwanda kwesimba uye kuverenga kwesero kwakakwira zvakanyanya, zvichiwedzera mukana wemhedzisiro yakaoma.

3. Kusaenzana pakati peBattery Cells

Mune akawanda-sero bhatiri mapaketi, kunyanya ayo ane yakakwirira voltage masisitimu senge mota dzemagetsi, kuenzanisa voltage pakati pemasero kwakakosha. Iyo BMS ine basa rekuona kuti maseru ese ari mupakeji akaenzana. Kana BMS ikakundikana, mamwe maseru anogona kukwizwa asi mamwe achiramba akachajiswa. Mune masisitimu ane tambo dzebhatiri dzakawanda, kusaenzana uku hakungodzikisi kugona kwese asiwo kunoisa njodzi yekuchengetedza. Masero akawandisa ari panjodzi yekupisa zvakanyanya, izvo zvinogona kuita kuti akundikane zvine njodzi.

4. Kurasika Kwekutarisa uye Kurodha Data

Mumabhatiri masisitimu akaomarara, akadai seaya anoshandiswa mukuchengetedza simba kana mota dzemagetsi, BMS inoramba ichitarisa mashandiro ebhatiri, kutema data pamachaji ekutenderera, voltage, tembiricha, uye hutano hwesero. Ruzivo urwu rwakakosha pakunzwisisa hutano hwemabhatiri mapaketi. Kana iyo BMS ikakundikana, iyi yekutarisisa yakakosha inomira, zvichiita kuti zvisaite kutarisa kuti maseru ari mupakiti ari kushanda sei. Kune yakakwira voltage bhatiri masisitimu ane akawanda akateedzana maseru, kusakwanisa kutarisa hutano hwesero kunogona kukonzera kukundikana kusingatarisirwe, sekunge kuparara kwemagetsi nekukurumidza kana zviitiko zvinopisa.

5. Simba Kukundikana kana Kuderedza Kubudirira

BMS yakakundikana inogona kukonzera kudzikiswa kwekuita zvakanaka kana kutotadza zvachose simba. Pasina manejimendi akakodzera evoltage, tembiricha, uye kuenzanisa kwesero, iyo system inogona kuvharika kudzivirira imwe kukuvara. Mumaapplication apohigh-voltage bhatiri tambovanobatanidzwa, semotokari dzemagetsi kana kuchengetedzwa kwesimba reindasitiri, izvi zvinogona kutungamirira kukurasikirwa kwesimba kamwe kamwe, zvichiunza njodzi huru dzekuchengetedza. Somuenzaniso, aternary lithiumbhatiri pack rinogona kudzima zvisingatarisirwi motokari yemagetsi ichifamba, zvichigadzira mamiriro ekutyaira ane njodzi.
