Kev them nqi ceev thiab sijhawm rau EVs tuaj yeem sib txawv nyob ntawm ntau yam, suav nrog kev them nqi hluav taws xob, EV lub roj teeb loj thiab muaj peev xwm, qhov kub thiab txias, thiab qib them.
Muaj peb theem pib them rau EVs
Theem 1 Them Nqi: Qhov no yog txoj kev qeeb tshaj plaws thiab muaj zog tsawg tshaj plaws ntawm kev them nqi EV. Theem 1 kev them nyiaj siv tus qauv 120-volt hauv tsev qhov hluav taws xob thiab tuaj yeem siv sijhawm txog 24 teev kom them tag nrho EV.
Theem 2 Them Nyiaj: Txoj kev them nyiaj EV no nrawm dua li Qib 1 thiab siv lub qhov hluav taws xob 240-volt lossis lub chaw them nyiaj tshwj xeeb. Theem 2 them tuaj yeem siv sijhawm li 4-8 teev kom them tag nrho EV, nyob ntawm seb lub roj teeb loj thiab them ceev.
DC Fast Charging: Qhov no yog txoj kev ceev tshaj plaws ntawm kev them nqi EV thiab feem ntau pom ntawm cov chaw them nqi pej xeem. DC them ceev ceev tuaj yeem siv sijhawm li 30 feeb kom them tus nqi EV mus txog 80% muaj peev xwm, tab sis qhov kev them nqi ceev yuav txawv nyob ntawm tus qauv EV thiab lub chaw them nqi hluav taws xob.
Txhawm rau xam lub sijhawm them nyiaj rau EV, koj tuaj yeem siv tus qauv
Lub Sijhawm Them Nqi = (Lub Zog Muaj Peev Xwm x (Lub Hom Phiaj SOC - Pib SOC)) Kev Them Nqi
Piv txwv li, yog tias koj muaj EV nrog lub roj teeb 75 kWh thiab xav kom them nws los ntawm 20% mus rau 80% siv Theem 2 charger nrog 7.2 kW them ceev, kev suav yuav yog
Them sij hawm = (75 x (0.8 - 0.2)) / 7.2 = 6.25 teev
Qhov no txhais tau hais tias nws yuav siv sijhawm li 6.25 teev kom them koj EV ntawm 20% mus rau 80% siv Theem 2 charger nrog 7.2 kW them ceev. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub sij hawm them nyiaj tuaj yeem sib txawv nyob ntawm qhov chaw them nyiaj, tus qauv EV, thiab qhov kub thiab txias.
