Nhau - Kurasikirwa kweLithium Battery Range Range muNguva yechando? Mazano Akakosha neBattery Management System

Sezvo tembiricha ichidzikira, varidzi vemotokari dzemagetsi (EV) vanowanzo sangana nedambudziko rinoshungurudza: kudzikira kwehuwandu hwemabhatiri e lithium. Kutonhora kunoderedza kushanda kwemabhatiri, zvichikonzera kudzimwa kwemagetsi kamwe kamwe uye kupfupika kwekufamba—kunyanya munzvimbo dzekuchamhembe. Nerombo rakanaka, nekuchengetedzwa kwakakodzera uye kuchengetedzwa kwakavimbika.Sisitimu Yekutarisira Mabhatiri (BMS), matambudziko aya anogona kuderedzwa zvinobudirira. Pazasi pane mazano akasimbiswa ekuchengetedza mabhatiri e lithium uye kuchengetedza mashandiro munguva yechando ino.

Kutanga, shandisa magetsi anochaja zvishoma nezvishoma. Kupisa kwakaderera kunoderedza kufamba kwemaion mukati memabhatiri e lithium. Kushandisa magetsi akakwira (1C kana kupfuura) semuzhizha kunoita kuti simba risingapindike rive kupisa, izvo zvinogona kukonzera kuzvimba uye kuora kwebhatiri. Nyanzvi dzinokurudzira kuchaja pa 0.3C-0.5C munguva yechando—izvi zvinobvumira maion kupinda zvinyoro-nyoro muma electrodes, zvichiita kuti kuchaja kwakazara kuwedzere uye kuderedza kupfeka. HunhuSisitimu Yekutarisira Mabhatiri (BMS)inoongorora magetsi anochaja panguva chaiyo kudzivirira kuwandisa kwemagetsi.

Chechipiri, iva nechokwadi chekuti tembiricha yekuchaja iri pamusoro pe0℃. Kuchaja mumamiriro ezvinhu asina zero kunogadzira lithium dendrites, iyo inokuvadza masero ebhatiri uye inoisa njodzi kuchengetedzeka. Mhinduro mbiri dzinoshanda: tora rwendo rupfupi rwemaminitsi mashanu kusvika gumi kuti udziyise bhatiri usati wachaja, kana kuisa firimu rekudziyisa rakabatana neBMS.BMS inotanga kushanda yogakana kudzima hita kana tembiricha yebhatiri yasvika padanho rakatarwa, zvichibvisa tsika dzine njodzi dzakadai sekudziisa moto wakavhurika.

Chechitatu, deredza kudzika kwekubuda kwemagetsi (DOD) kusvika ku80%. Kuburitsa mabhatiri e lithium zvizere munguva yechando (100% DOD) kunokonzera kukuvara kwemukati kusingadzoreki, zvichikonzera matambudziko e "virtual power". Kumisa kuburitsa mabhatiri kana simba re20% richiripo kunoita kuti bhatiri rirambe riri munzvimbo ine mabasa akawanda, zvichiita kuti makiromita agare akadzikama. BMS yakavimbika inobatsira kudzora DOD pasina matambudziko kuburikidza nebasa rayo rekudzivirira kuburitsa mabhatiri.

Mamwe mazano maviri ekugadzirisa: dzivisa kuchengetedza kwenguva refu pasina kupisa kwakanyanya—isa maEV mumagaraji kudzivirira kurasikirwa zvachose kwebasa rebhatiri. Kune mabhatiri asingashande, kuchaja kwekuwedzera kusvika pa50%-60% pavhiki kwakakosha. BMS ine remote monitoring inobvumira vashandisi kuteedzera voltage netembiricha chero nguva, zvichiita kuti vagadziriswe nenguva.

Sisitimu yeBattery Management System (BMS) yemhando yepamusoro inokosha pakuchengetedza hutano hwebhatiri munguva yechando. Zvimiro zvayo zvepamusoro, zvinosanganisira kutarisa maparameter panguva chaiyo uye dziviriro yakangwara, inodzivirira mabhatiri kubva pakuchaja nekuburitsa magetsi zvisina kunaka. Nekutevera matipi aya uye kushandisa BMS yakavimbika, varidzi vemagetsi vanogona kuchengetedza mabhatiri avo e-lithium achishanda zvakanaka munguva yechando.
