Chifukwa cha makhalidwe alithiamu batirepalokha, kasamalidwe ka batri (BMS) iyenera kuwonjezeredwa.Mabatire opanda dongosolo loyang'anira ndi oletsedwa kugwiritsa ntchito, zomwe zidzakhala ndi zoopsa zazikulu zachitetezo.Chitetezo nthawi zonse chimakhala chofunikira pamakina a batri.Mabatire, ngati sanatetezedwe bwino kapena osayendetsedwa bwino, amatha kukhala ndi chiwopsezo chokhala ndi moyo wamfupi, kuwonongeka, kapena kuphulika.

BMS: (Battery Management System) imagwiritsidwa ntchito makamaka pamabatire amagetsi, monga magalimoto amagetsi, njinga zamagetsi, kusungirako mphamvu ndi machitidwe ena akuluakulu.

Ntchito zazikuluzikulu za kasamalidwe ka batire (BMS) zikuphatikiza mphamvu ya batri, kutentha ndi kuyeza kwapano, mphamvu yamagetsi, kuwerengera kwa SOC ndikuwonetsa, alamu yachilendo, kasamalidwe kachakudya ndi kutulutsa, kulumikizana, ndi zina zambiri, kuphatikiza ntchito zoyambira zoteteza chitetezo. .Ma BMS ena amaphatikizanso kasamalidwe ka kutentha, kutentha kwa batri, kusanthula thanzi la batri (SOH), kuyeza kukana kukana, ndi zina zambiri.

Chiyambi cha ntchito ya BMS ndi kusanthula:
1. Chitetezo cha batri, chofanana ndi PCM, kulipiritsa, kutulutsa, kutentha kwambiri, kupitilira apo, komanso chitetezo chafupipafupi.Monga mabatire wamba a lithiamu-manganese ndi zinthu zitatumabatire a lithiamu-ion, makinawo amangodula magetsi kapena kutulutsa dera akangozindikira kuti voteji iliyonse ya batri imaposa 4.2V kapena mphamvu ya batri iliyonse imagwera pansi pa 3.0V.Ngati kutentha kwa batri kumaposa kutentha kwa batire kapena kupitirira kutulutsa kwa batri, dongosololi limadula njira yamakono kuti iwonetsetse chitetezo cha batri ndi dongosolo.

2. Mphamvu yamagetsi, yonsebatire paketi, chifukwa cha mabatire ambiri mndandanda, pambuyo pogwira ntchito kwa nthawi inayake, chifukwa cha kusagwirizana kwa batri palokha, kusagwirizana kwa kutentha kwa ntchito ndi zifukwa zina, pamapeto pake kudzawonetsa kusiyana kwakukulu, kumakhudza kwambiri moyo wa betri ndi kugwiritsa ntchito dongosolo.Kuchuluka kwa mphamvu ndikupangitsa kusiyana pakati pa ma cell kuti azichita zinthu zina zogwira ntchito kapena zopanda pake kapena kasamalidwe kakutulutsa, kuwonetsetsa kuti batire imagwirizana, kutalikitsa moyo wa batri.Pali mitundu iwiri yokhazikika komanso yogwira ntchito mumakampani.Kuchuluka kwa mphamvu kumangotengera kuchuluka kwa mphamvu pogwiritsa ntchito kukana, pomwe mphamvu yogwira ntchito makamaka ndi kusamutsa kuchuluka kwa mphamvu kuchokera ku batri kupita ku batri yokhala ndi mphamvu zochepa kudzera pa capacitor, inductor kapena transformer.Kufanana kwapang'onopang'ono komanso kuchitapo kanthu kumafaniziridwa mu tebulo ili m'munsimu.Chifukwa chakuti dongosolo logwira ntchito lokhazikika ndilovuta kwambiri ndipo mtengo wake ndi wokwera kwambiri, okhazikika akadali osagwirizana.

3. Kuwerengera kwa SOC,mphamvu ya batrikuwerengera ndi gawo lofunika kwambiri la BMS, machitidwe ambiri amafunika kudziwa bwino kwambiri mphamvu yotsalayo.Chifukwa cha chitukuko cha teknoloji, kuwerengera kwa SOC kunasonkhanitsa njira zambiri, zofunikira zolondola sizili zapamwamba zimatha kutengera mphamvu ya batri kuti iweruze mphamvu yotsalayo, njira yolondola kwambiri ndi njira yophatikizana (yomwe imadziwikanso kuti Ah njira), Q = ∫i dt, komanso njira yotsutsa mkati, njira ya neural network, njira ya fyuluta ya Kalman.Kugoletsa kwakanthawi ikadali njira yayikulu pamsika.

4. Kulankhulana.Machitidwe osiyanasiyana ali ndi zofunikira zosiyana pazolumikizirana.Njira zoyankhulirana zazikuluzikulu zikuphatikiza SPI, I2C, CAN, RS485 ndi zina zotero.Makina osungira magalimoto ndi magetsi makamaka CAN ndi RS485.
