Nekuda kwehunhu hwebhatiri re lithiamupacharo, sisitimu yekutarisira mabhatiri (BMS) inofanira kuwedzerwa. Mabhatiri asina sisitimu yekutarisira haabvumirwi kushandiswa, izvo zvichave nenjodzi huru dzekuchengetedza. Kuchengetedzeka kunogara kuri chinhu chakakosha kune masisitimu emabhatiri. 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 semota dzemagetsi, mabhasikoro emagetsi, nzvimbo yekuchengetedza magetsi nedzimwe nzira huru.

Mabasa makuru ehurongwa hwekutarisira mabhatiri (BMS) anosanganisira voltage yebhatiri, kuyerwa kwetembiricha uye magetsi, kuenzana kwesimba, kuverenga nekuratidzwa kweSOC, alarm isina kujairika, manejimendi yekuchaja nekuburitsa, kutaurirana, nezvimwewo, kunze kwemabasa ekutanga ekudzivirira ehurongwa hwekudzivirira. Mamwe maBMS anosanganisirawo manejimendi yekupisa, kupisa bhatiri, kuongorora hutano hwebhatiri (SOH), kuyerwa kwekudzivirira kupisa, nezvimwewo.

Kutanga nekuongorora basa reBMS:
1. Dziviriro yebhatiri, yakafanana nePCM, kuchengetedzwa kwemagetsi zvakanyanya, kubudiswa kwemvura zvakanyanya, kupisa kwakanyanya, magetsi akawanda, uye kuchengetedzwa kwemhepo pfupi. Sezvakaita mabhatiri e lithium-manganese uye ane zvinhu zvitatumabhatiri e lithiamu-ion, sisitimu inodzima otomatiki chiteshi chekuchaja kana chekuburitsa magetsi kana yaona kuti chero voltage yebhatiri inodarika 4.2V kana chero voltage yebhatiri inowira pasi pe3.0V. Kana tembiricha yebhatiri inopfuura tembiricha yekushanda yebhatiri kana simba remagetsi richipfuura simba remagetsi rekuburitsa magetsi rebhatiri, sisitimu inodzima otomatiki nzira yemagetsi kuti ive nechokwadi chekuti bhatiri nehurongwa hwakachengeteka.

2. Kuenzana kwesimba, zvesebhatiri, nekuda kwemabhatiri akawanda akatevedzana, mushure mekushanda kwenguva yakati, nekuda kwekusagadzikana kwebhatiri pacharo, kusagadzikana kwekupisa kwekushanda nezvimwe zvikonzero, pakupedzisira kucharatidza mutsauko mukuru, kune simba guru pahupenyu hwebhatiri nekushandiswa kwesystem. Simba rakaringana nderekutsiva mutsauko uripo pakati pemasero ega ega kuti uite imwe active kana passive charge kana discharge management, kuve nechokwadi chekuti bhatiri rinogara kwenguva refu, kuwedzera hupenyu hwebhatiri. Kune mhando mbiri dze passive balance uye active balance muindasitiri. Passive balance inonyanya kuyera huwandu hwesimba kuburikidza nekushandiswa kwe resistance, nepo active balance inonyanya kuendesa huwandu hwesimba kubva kubhatiri kuenda kubhatiri nesimba shoma kuburikidza ne capacitor, inductor kana transformer. Passive uye active equilibria zvinoenzaniswa mutafura iri pazasi. Nekuti active equilibrium system yakaoma uye mutengo wakakwira, mainstream ichiri passive equilibrium.

3. Kuverenga kweSOC,simba rebhatiriKuverenga chikamu chakakosha cheBMS, masisitimu mazhinji anofanirwa kuziva zvakanyatsonaka mamiriro esimba rasara. Nekuda kwekuvandudzwa kwetekinoroji, kuverenga kweSOC kwakaunganidza nzira dzakawanda, zvinodiwa zvekunyatsojeka hazvisi zvepamusoro zvinogona kutsamira pamagetsi ebhatiri kutonga simba rasara, nzira huru yakarurama ndiyo nzira yekubatanidza iripo (inozivikanwawo seAh method), Q = ∫i dt, pamwe nenzira yekudzivirira mukati, nzira yeneural network, nzira yeKalman filter. Kuverenga kwazvino kuchiri nzira huru muindasitiri.

4. Kutaurirana. Masisitimu akasiyana ane zvinodiwa zvakasiyana zvekutaurirana. Masangano makuru ekutaurirana anosanganisira SPI, I2C, CAN, RS485 nezvimwewo. Masisitimu ekuchengetedza mota nemagetsi anonyanya kuve CAN neRS485.
