Momwe Mungathetsere Kusalingana kwa Mphamvu ya Voltage mu Mapaketi a Lithium Battery

Kusalingana kwa mphamvu yamagetsi m'mabatire a lithiamu ndi vuto lalikulu kwa ma EV ndi makina osungira mphamvu, zomwe nthawi zambiri zimayambitsa kutha kwa chaji, nthawi yochepa yogwirira ntchito, komanso zoopsa zachitetezo. Kuti vutoli lithe bwino, kugwiritsa ntchito Battery Management System (BMS) ndi kukonza koyenera ndikofunikira kwambiri.

Choyamba,yambitsani ntchito yolinganiza ya BMS. Advanced BMS (monga omwe ali ndi active balancing) imasamutsa mphamvu kuchokera ku maselo amphamvu kupita ku maselo otsika mphamvu panthawi yochaja/kutulutsa mphamvu, kuchepetsa kusiyana kwa mphamvu. Pa BMS yopanda mphamvu, chitani "full-charge static balancing" pamwezi - lolani batri lipumule maola 2-4 mutachaja mokwanira kuti BMS igwirizane ndi ma voltage.

Chachiwiri, yang'anani kulumikizana ndi kukhazikika kwa maselo. Mabasi a mkuwa otayirira kapena malo olumikizirana odetsedwa amawonjezera kukana, ndikuwonjezera kutsika kwa magetsi. Tsukani kukhudzana ndi mowa ndikulimbitsa mtedza; sinthani ziwalo zomwe zawonongeka. Komanso, gwiritsani ntchito maselo a lithiamu ofanana (omwe ayesedwa kuti apeze kusiyana kwa ≤5% kwa kukana kwamkati) kuti mupewe kusalinganika komwe kulipo.

Pomaliza, konzani bwino momwe magetsi amayendera komanso kutulutsa mphamvu. Pewani kugwiritsa ntchito mphamvu yamagetsi yapamwamba (monga kuthamanga kwa EV mwachangu) chifukwa mphamvu yamagetsi yapamwamba imawonjezera kutsika kwa magetsi. Gwiritsani ntchito ma charger olamulidwa ndi BMS omwe amatsatira mfundo ya "pre-charge → constant current → constant voltage", zomwe zimachepetsa kuchulukana kwa magetsi osalinganika.

Mwa kuphatikiza magwiridwe antchito a BMS ndi kukonza mosamala, mutha kuthetsa kusalinganika kwa mphamvu zamagetsi ndikuwonjezera nthawi ya batire ya lithiamu.
