AC J1772: Overview, Significance, and Compatibility with EVs
The connectors are key in bridging the gap between the electric vehicle and power sources. You cannot deny its role in contributing to sustainable transportation. The only issue many EV owners face is the incompatibility of the connector with their EVs. This prevents them from charging their EVs and continuing their ride.
It also raises the difficulties in locating the EV charging station that features the connectors that their vehicle can support. Connecting the wrong connector along with the adapter can damage the vehicle’s charging system and batteries. Therefore, this is not feasible.
This article highlights the AC J1772 connectors’ importance and compatibility level. Sounds great? Don’t stop reading.We also introduced EV Charging Station Voltage: Specifications, Compatibility, and Considerations in our previous articles. Hope it will be helpful to you.
AC J1772 – A Short Overview
The J1772 refers to a connector that works on an AC (Alternating Current) source. It offers perfect compatibility with the Level 1 and Level 2 chargers. You can set up the chargers featuring the J1772 connector to both input sources, 120 V or 240 V. It can offer a power output ranging from 1.6 kW to 19.8 kW.
The J1772 is a standard outlet when it comes to charging EVs. There are several EV manufacturers which use J1772 as a standard outlet. But in these manufacturers, the Tesla is not included. However, you can connect the Tesal to the J1772 connector using an adapter for smooth charging. The J1772 supports the single-phase charging at super convenience.
Description of The J1772
AC J1772 comprises the 5 total pins. The upper three pins refer to the pins that play a key role in connection to the Neutral AC, ACLine 1, and the protective earth (PE). The Control Pilot (CP) and Proximity Pilot (PP) roles are two smaller pins on the bottom. These two pins are communication and safety points between the charging station and the EV (Electric Vehicle).
|Sr. No.||Charge method||Voltage (V)||Phase||Max. Current,|
breaker rating (A)
|Max. Power (kW)|
|1||AC Level 1||120||1||12||15||1.44|
|3||AC Level 2||208 or 240||1||24–80||30–100||5.0–19.2|
Using the J1772 connector, you can charge your vehicle at two speeds.
When it comes to level 1 charging, using it for 20 hours, you can get a travel distance of 140 miles or more.
On the other hand, for Level 2 charging, using it for 4 to 6 hours, you can get 150 miles or more. The level 2 J1772 connectors offer 3 to 7 times faster charging than those of level 1 J1772.
This is mainly because when you connect the J1772 to 120 V output and a capacity of 16 amperes, you can get a power output of 1.92kW.
In contrast, connecting the J1772 with the 208 V to 240 V input with a total capacity of 80 Amp. In this way, you can get a power output of 19.8 kW.
AC J1772 – Working Mechanism
The working mechanism of the AC J1772 involves multiple steps. Some key steps you need to note include:
Insertion of Plug
At first, the EV owner needs to put the AC J1772 plug within the vehicle charging port. The owner can do this by using the cable attached to the connector on the EV Charging station. On the other hand, you can also do this by using the cable and plug that comes with the EV purchase. This eliminates the need for usage of the station cable.
multiple communication protocols exist when it comes to the AC J1772. These protocols include WiFi or RFID. This determines the compatibility with the charging station for the specific EV model. This authentication copes with the safe and secure charging process. It also prevents damage to the vehicle’s charging accessories, including batteries.
Flow of Power
After the completion of the authentication successfully, the power goes directly from the AC EV charger station to the vehicle’s charger. The connector pins provide the medium for this operation. If these pins do not exist, no power transfer occurs through the AC J1772 connector.
Later, the AC power is transformed into the DC. The inverter plays a great role in this regard. The main purpose of this conversion is that the DC charging is much faster than the AC charging. This way, you can successfully charge your batteries on the go.
Control for Charging
Controlling the charging is crucial to maintaining the optimum health of the battery and charging systems. This is crucial to manage the battery status, electricity flow, and charging rate. The optimum charging control also ensures a longer battery and vehicle life.
This is how the AC J1772 works. The working process indicates the significance level for charging your vehicle and the EV charging station.
The Significance/Importance of The AC J1772
The multiple reasons reflect the importance and significance of the AC J1772. Some of the key reasons for your attention include the following:
Using the AC j1772 offers you with the unmatchable convenience. With the AC J1772, you don’t need to employ other adapters. You can use it with multiple charging stations on the go. This connector prevents the users from locating compatible charging stations. Hence, you can save your time and money. You can contact any nearby EV charging station to hook up your vehicle.
Extra Travel Range
Using the AC j1772, you can reach out to any nearby charging station. This ensures you always get the maximum travel range and stay charged. You don’t need to remain in stress and anxiety when it comes to vehicle charging. This makes more and more individuals transfer to electric vehicles.
