Mabhatiri eLithium ave chikamu chakakosha chesimba idzva, achipa simba kune zvese kubva kumotokari dzemagetsi nenzvimbo dzekuchengetera simba kusvika kumagetsi anotakurika. Asi, dambudziko rinowanzo sangana nevashandisi pasi rese idambudziko guru rekupisa pakushanda kwebhatiri—zhizha rinowanzo unza matambudziko akadai sekuzvimba kwebhatiri uye kubuda kwemvura, nepo nguva yechando ichikonzera kudzikira kwakanyanya kwenzvimbo uye kusashanda zvakanaka kwekuchaja. Izvi zvinobva mukunzwa kwekupisa kwemabhatiri eLithium, ane mabhatiri eLithium Iron phosphate, rimwe remhando dzinoshandiswa zvakanyanya, rinoshanda zvakanaka pakati pe0°C ne40°C. Mukati meiyi nzira, maitiro emakemikari emukati uye kufamba kwemaion zvinoshanda zvakanyanya, zvichiita kuti simba ribude zvakanyanya.
Tembiricha dziri kunze kwehwindo iri rakachengeteka dzinokonzera njodzi huru kumabhatiri e-lithium. Munzvimbo dzine tembiricha yepamusoro, electrolyte volatilization uye kuora zvinokurumidza, zvichideredza conductivity ye-ion uye zvinogona kugadzira gasi rinokonzera kuzvimba kana kuputika kwebhatiri. Uyezve, kugadzikana kwechimiro chezvinhu zve-electrode kunoderera, zvichikonzera kurasikirwa kwesimba risingadzoreki. Kunyanya kukosha, kupisa kwakanyanya kunogona kukonzera kuti kupisa kumhanye, ketani inogona kukonzera zviitiko zvekuchengetedza, izvo zviri chikonzero chikuru chekusashanda zvakanaka kwemidziyo mitsva yesimba. Tembiricha dzakaderera dzine dambudziko rakaenzana: kuwedzera kwe electrolyte viscosity kunoderedza kufamba kwe lithium ion, kukwidza resistance yemukati uye kuderedza kushanda kwechaja-kuburitsa. Kuchaja kwakasimba mumamiriro ekunze anotonhora kunogona kukonzera kuti lithium ions ipinde pamusoro pe electrode isina kunaka, zvichigadzira lithium dendrites dzinoboora separator uye dzinokonzera internal short circuits, zvichikonzera njodzi huru dzekuchengetedza.
Kuti kuderedze njodzi idzi dzinokonzerwa nekupisa, Lithium Battery Protection Board, inozivikanwa seBMS (Battery Management System), inokosha. Zvigadzirwa zveBMS zvemhando yepamusoro zvine masensa ekupisa eNTC anonyatsoongorora kupisa kwebhatiri. Kana kupisa kuchipfuura miganhu yakachengeteka, sisitimu yacho inotanga kurira; kana kupisa kuchikwira nekukurumidza, inomhanyisa matanho ekudzivirira kuti ibvise circuit, ichidzivirira kukuvara kwakawanda. BMS yepamusoro ine low-tembiricha heating control logic inogonawo kugadzira mamiriro ekushanda akakodzera emabhatiri munzvimbo dzinotonhora, ichigadzirisa zvinobudirira matambudziko akadai sekudzikira kwenzvimbo uye matambudziko ekuchaja, ichivimbisa kushanda kwakasimba mumamiriro akasiyana-siyana ekupisa.
Sechikamu chikuru chekuchengetedza mabhatiri e lithium, BMS inoshanda zvakanyanya haingori chete kuchengetedza kuchengetedzwa kwekushanda asiwo inowedzera hupenyu hwebhatiri, ichipa rutsigiro rwakakosha pakushanda kwakavimbika kwemidziyo mitsva yesimba.
