Nekuda kwehunhu hwelithium bhatiripachayo, bhatiri management system (BMS) inofanira kuwedzerwa.Mabhatiri asina manejimendi system anorambidzwa kushandisa, ayo anozova nenjodzi huru dzekuchengetedza.Kuchengetedzeka kunogara kuchikosha kune mabhatiri masisitimu.Mabhatiri, kana asina kuchengetedzwa zvakanaka kana kutarisirwa zvakanaka, anogona kuva nenjodzi yehupenyu hupfupi, kukuvara, kana kuputika.

BMS: (Battery Management System) inonyanya kushandiswa mumabhatiri emagetsi, akadai semotokari dzemagetsi, mabhasikoro emagetsi, kuchengetedza simba uye mamwe maitiro makuru.

Iwo makuru mabasa ebhatiri manejimendi system (BMS) anosanganisira bhatiri voltage, tembiricha uye kuyerwa kwazvino, chiyero chesimba, kuverenga kweSOC uye kuratidza, abnormal alarm, charge uye discharge manejimendi, kutaurirana, nezvimwewo, kunze kwemabasa ekudzivirira ekuchengetedza system. .Imwe BMS inobatanidzawo kutonga kwekupisa, kupisa kwebhatiri, hutano hwebhatiri (SOH) kuongororwa, kuyerwa kwekudzivirira kwekudzivirira, nezvimwe.

BMS basa sumo uye ongororo:
1. Kudzivirirwa kwebhatiri, yakafanana nePCM, pamusoro pechaji, pamusoro pekubuda, pamusoro pekushisa, pamusoro pemazuva ano, uye kuchengetedzwa kwedunhu pfupi.Kufanana neyakajairwa lithium-manganese mabhatiri uye matatu-elementlithium-ion mabhatiri, sisitimu yacho inodzima pachaji kana kuburitsa dunhu kana yaona kuti chero bhatiri voltage inodarika 4.2V kana chero bhatiri voltage inowira pasi pe3.0V.Kana tembiricha yebhatiri ichipfuura tembiricha yekushandisa yebhatiri kana yazvino inodarika kubuda kwedziva rebhatiri, sisitimu inodzima nzira yazvino kuti ive nechokwadi chekuchengetedza bhatiri uye system.

2. Simba rekuenzanisa, rosebhatiri pack, nekuda kwemabhatiri akawanda munhevedzano, mushure mekushanda kweimwe nguva, nekuda kwekusawirirana kwebhatiri pachayo, kusawirirana kwekushisa kwekushanda uye zvimwe zvikonzero, pakupedzisira zvicharatidza kusiyana kukuru, kune simba guru pahupenyu hwe bhatiri uye kushandiswa kwehurongwa.Energy balance ndeyekugadzirisa misiyano pakati pemaseru ega ega kuita imwe inoshanda kana passive charge kana discharge management, kuve nechokwadi chekuenderana kwebhatiri, kurebesa hupenyu hwebhatiri.Kune mhando mbiri dze passive balance uye inoshanda chiyero muindasitiri.Passive balance inonyanya kuenzanisa huwandu hwesimba kuburikidza nekushandisa kushandiswa, nepo chiyero chinoshanda chiri kunyanya kuendesa huwandu hwesimba kubva kubhatiri kuenda kubhatiri ine simba shoma kuburikidza necapacitor, inductor kana transformer.Passive uye inoshanda yakaenzana inofananidzwa mutafura iri pazasi.Nekuti iyo inoshanda equilibrium system haina kuoma uye mutengo wakakwira zvakati wandei, iyo mainstream ichiri passive equilibrium.

3. SOC kuverenga,bhatiri simbakukarukureta chikamu chakakosha cheBMS, masisitimu mazhinji anofanirwa kuziva zvakanyanya iyo yasara simba mamiriro.Nekuda kwekuvandudzwa kwetekinoroji, kuverenga kweSOC kwakaunganidza nzira dzakawanda, kudiwa chaiko hakuna kukwirira kunogona kuenderana nebhatiri voltage kutonga simba rasara, nzira huru yakarurama ndiyo nzira yekubatanidza iripo (inozivikanwawo seAh nzira), Q = ∫i dt, uyewo nzira yekudzivirira mukati, neural network nzira, Kalman filter nzira.Ikozvino zvibodzwa ichiri nzira huru muindasitiri.

4. Kukurukurirana.Masisitimu akasiyana ane zvinodiwa zvakasiyana zvemafambisirwo ekutaurirana.Iyo huru yekutaurirana inopindirana inosanganisira SPI, I2C, CAN, RS485 zvichingodaro.Mota uye simba rekuchengetedza masisitimu ndiwo anonyanya CAN uye RS485.
