Incorrect. J1772 Jan 2010 clearly states that Level 1 can be connected via plug but Level 2 must be hard-wired to a 240V source.
Page 9 Table 1
This might be useful...
From J1772 Jan 2010 page 7 section 3.2 (Definitions)
3.2 AC Level 2 Charging
A method that uses dedicated AC EV/PHEV supply equipment in either private or public locations. The vehicle shall be fitted with an on-board charger capable of accepting energy from single phase alternating current (AC) electric vehicle supply equipment. The maximum power supplied for AC Level 2 charging shall confirm to the values in Table 1.
From Table 1 - CHARGE METHOD ELECTRICAL RATINGS (NORTH AMERICA)
Charge Method / Supply Voltage / Max Current / Branch Circuit Breaker Rating
AC Level 1 / 120V AC / 12A / 15A
AC Level 1 / 120V AC / 16A / 20A
AC Level 2 / 208-240VAC / less than or equal to 80A / Per NEC 625
Could it be that while we're allowed to connect our electric stoves with a plug, we're not allowed to connect 80A devices with a plug? Just guessing here... What's the max rating of a dryer plug, range plug, or 50A RV connector?
