Electric vehicle charging connector in North America / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about SAE J1772?
Summarize this article for a 10 years old
SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".
|Type||Automotive power connector|
|Length||33.5 millimetres (1.32 in)|
|Diameter||43.8 millimetres (1.72 in)|
|Data signal||SAE J1772: Resistive / Pulse-width modulation|
|Pinouts for CCS Combo 1, looking at end of plug (attached to EVSE cord)|
|L1||Line 1||single-phase AC|
|L2/ N||Line 2 /Neutral||single-phase AC|
|CP||Control pilot||post-insertion signalling|
|PP||Proximity pilot||pre-insertion signalling|
|PE||Protective earth||full-current protective earthing system|
|CCS Combo 1 extension adds two extra high-current DC pins underneath, and the two Alternating Current (AC) pins for Neutral and Line 1 are not populated.|
The SAE maintains the general physical, electrical, communication protocol, and performance requirements for the electric vehicle conductive charge system and coupler. The intent is to define a common electric vehicle conductive charging system architecture including operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.
The J1772 5-pin standard supports a wide range of single-phase (1φ) alternating current (AC) charging rates. They range from portable devices that can connect to a household NEMA 5-15 outlet that can deliver 1.44 kW (12 A @ 120 V) to hardwired equipment that can deliver up to 19.2 kW (80 A @ 240 V). These connectors are sometimes informally referred to as chargers, but they are "electric vehicle supply equipment" (EVSE), since they only supply AC power to the vehicle's on-board charger, which then converts it to the direct current (DC) needed to recharge the battery.
The Combined Charging System (CCS) Combo 1 connector builds on the standard, adding two additional pins for DC fast charging up to 350 kW.
