The maximum voltage rating of IEC 60309 connectors is 1000 V DC or AC; the maximum current rating is 800 A; and the maximum frequency 500 Hz. Plugs are available in P+N+E (unbalanced single phase with neutral), 2P+E (balanced single phase), 3P+E (3 phase without neutral), and 3P+N+E (three phase with neutral).
This process led to the proposal of a new round connector design by Yazaki which allowed for an increased power delivery of up to 19.2 kW delivered via single phase 120–240 V AC at up to 80 amps. In 2008, CARB published a new standard that mandated the usage of the new connector beginning with the 2010 model year; [ 7 ] this was approved in 2012.
The Type 2 connector has a maximum power output for 43 kW and can handle both single-, dual- and three-phase AC power. The IEC 62196-2 Type 1 connector (codified under SAE J1772) is the corresponding standard for single-phase AC charging in the United States, Canada, and South Korea. [12] J1772 has a maximum output of 19.2 kW. [13]
Single-phase 6-50 is commonly used on farms for silo unloaders, and is used with a 6-gauge flexible power cord up to 200 ft (61 m) long. The 6-50 receptacle charges electric vehicles at the same 32- or 40-ampere maximum from charging stations , on a short cord, as the more versatile 14-50 with its fourth prong neutral not used currently for any ...
Given that a 480Y/277 VAC three-phase wye-connected four-wire supply is a common configuration supplied by utilities at commercial locations – under SAE J3400 and SAE J3068 the implied higher rating is taken; thus allowing single-phase charging at 277 VAC nominal for North American application.
Single-phase AC: 120 V 12 A 1.44 kW 13 hours This is the maximum continuous power available from a standard US/Canadian 120 V 15 A circuit Single-phase AC: 230 V 16 A 3.68 kW 5.1 hours This is the maximum continuous power available from a CEE 7/3 ("Schuko") receptacle on a 16 A rated circuit Single-phase AC: 240 V 30 A 7.20 kW 2.6 hours
Where two voltages are given below separated by "/", the first is the root-mean-square voltage between a phase and the neutral connector, whereas the second is the corresponding root-mean-square voltage between two phases (exception: the category shown below called "One Phase", where 240 V is the root-mean-square voltage between the two legs of a split phase).
The connector is circular in shape, with a flattened top edge; the original design specification carried an output electric power of 3–50 kW for charging battery electric vehicles using single-phase (230V) or three-phase (400V) alternating current (AC), with a typical maximum of 32 A 7.2 kW using single-phase AC and 22 kW with three-phase AC ...
