North America lub 120/240V split-phase system txwv AC charging rau qhov siab tshaj plaws ntawm 19.2kW ntawm 100A circuit, yog vim li cas kev lag luam hauv Asmeskas thiaj li siv DC fast charging ntau dua rau kev ceev.

• Kev Hloov Pauv NACS:Nrog Tesla's North American Charging Standard (NACS) tam sim no tau txais yuav los ntawm yuav luag txhua lub tuam txhab tsim tsheb loj, cov chaw them hluav taws xob DC tshiab yuav tsum muaj cov khoom sib txuas NACS (hom qub lossis ob txoj hlua) kom tseem siv tau thoob plaws lub sijhawm hloov pauv xyoo 2025-2030.
• Kev Ua Raws Cai ntawm NEC:Cov chaw teeb tsa hauv Tebchaws Meskas ua raws li National Electrical Code, suav nrog cov kev cai GFCI, kev suav cov khoom thauj, thiab cov ntu tshiab ntawm EVSE tshwj xeeb ntawm 2023 code uas suav nrog kev kaw sai thiab kev txiav tawm.

Xaus Lus: Tsim Ib Zaug, Tso Tawm Txhua Qhov Chaw

Cov kev sib txawv ntawm cov cheeb tsam—peb-theem vs. faib-theem, Hom 2 vs. J1772 vs. GB/T, 50Hz vs. 60Hz—yog qhov tseeb tab sis tswj tau. Lub tswv yim yeej yog cov khoom siv modular: cov chargers uas lawv lub zog theem lees txais txhua qhov kev nkag hauv cheeb tsam, uas lawv cov kev xaiv txuas yog qhov hloov pauv tau, thiab uas lawv cov software ua raws li cov txheej txheem hauv zos thiab cov lej grid. Cov neeg teb xov tooj uas ua tus qauv ntawm cov platforms no tuaj yeem rov ua lawv tus qauv lag luam thoob plaws cov teb chaws yam tsis tau rov ua dua tshiab.

Cov Ntsiab Lus Tseem Ceeb

• Teb chaws Europe: 230/400V peb-theem ua rau 22kW AC them; Hom 2 thiab CCS2 tseem ceeb; AFIR tsav cov kev cai qhib-nkag.
• Asia-Pacific: GB/T thiab tus qauv ChaoJi tshiab ua rau lub ntiaj teb hauv kev them ceev thiab ntim ceev heev.
• Tebchaws Asmeskas Qaum Teb: Lub zog faib ua ob ntu nyiam DC them ceev; NACS tab tom dhau los ua qhov txuas DC de facto.
• Cov khoom siv modular, ntau tus qauv yog qhov tseem ceeb rau kev lag luam them hluav taws xob thoob ntiaj teb.
