Mubvunzo unowanzo bvunzwa ndewekuti: BMS yebhatiri re lithium-ion inoita kuti dziviriro yekuchaja yakawandisa ishande mumamiriro api ezvinhu, uye ndeipi nzira chaiyo yekupora kubva pairi?
Dziviriro yekuchaja zvakanyanya yemabhatiri e lithium-ion inokonzereswa kana chimwe chezviviri izvi chaitwa. Chekutanga, sero rimwe chete rinosvika pavoltage yaro yekuchaja zvakanyanya. Chechipiri, voltage yese yebhatiri inosangana nechiyero chekuchaja zvakanyanya. Semuenzaniso, masero e lead-acid ane voltage yekuchaja yakawanda ye3.65V, sakaBMSkazhinji inoisa voltage yekuwedzera simba remagetsi kune imwe sero kusvika pa3.75V, nekudzivirira kwemagetsi ese kunoverengwa se3.7V kwakawedzerwa nenhamba yemasero. Kune mabhatiri e-ternary lithium, voltage yekuchaja yakazara i4.2V pasero rega rega, saka dziviriro yeBMS single-cell overcharge inoiswa pa4.25V, uye mamiriro ekudzivirira simba rese i4.2V kakawanda kupfuura nhamba yemasero.
Mubvunzo unowanzo bvunzwa nevashandisi ndewekuti: Kusiya bhatiri reEV rakachajwa husiku hwese (kubva pakati pehusiku kusvika mangwana acho) kunorikuvadza here nekufamba kwenguva? Mhinduro yacho inoenderana nehurongwa hwacho. Kana bhatiri nechaja zviri zvemugadziri wemidziyo yekutanga (OEM) zvakafanana, hapana chikonzero chekunetseka - BMS inopa dziviriro yakavimbika. Kazhinji, voltage yekudzivirira yekuchaja zvakanyanya yeBMS inoiswa pamusoro pemagetsi anobuda muchaja. Kana masero achiramba akasimba (senge mumabhatiri matsva), dziviriro yekuchaja zvakanyanya haizokonzere mushure mekuchaja zvizere. Sezvo bhatiri richikura, kusimba kwemasero kunoderera, uye BMS inotanga kushanda kuti ipe dziviriro.
Zvinonyanya kukosha, pane musiyano wemagetsi pakati peBMS's overcharge trigger voltage uye recovery threshold. Iyi reserved voltage range inodzivirira kutenderera kunokuvadza: kudzivirira → kudonha kwemagetsi → kuburitswa kwekudzivirira → kuchajazve → kudzivirirazve, izvo zvinobatsira kuwedzera hupenyu hwebasa rebhatiri. Kuti bhatiri rigare kwenguva refu uye rakachengeteka, nzira yakanakisisa ndeyekuchaja kana uchida uye kubvisa charger kana bhatiri rachaja zvizere.
