Comparing j1772 connector and CCS connector

Tesla EV


As electric cars gain traction, understanding charging standards like j1772 and CCS becomes crucial. In this article, we'll delve into the specifics of each standard, their advantages, and which might suit your EV charging needs better.

Understanding j1772 vs CCS

Explaining j1772:

j1772, also known as the “J-plug,” is a standard connector widely used in North America for Level 1 and Level 2 charging. It features a unique J-shaped plug with five pins, supporting both AC and DC charging.

Understanding CCS:

CCS, or Combined Charging System, is a global standard integrating AC and DC charging into a single plug. It’s characterized by two additional DC pins on top of the j1772 connector, enabling faster DC charging.

Comparison: j1772 vs CCS


1.j1772:The j1772 connector is compatible with most electric vehicles in North America, primarily supporting AC charging. However, it may not be compatible with high-speed DC charging networks.

2.CCS:CCS offers broader compatibility, supporting both AC and DC charging. Many newer electric vehicles come equipped with CCS ports, making it versatile for charging on various networks.

Charging Speed

1.j1772:While j1772 connectors support Level 2 charging, they’re not optimized for rapid DC charging, potentially resulting in longer charging times.

2.CCS:CCS excels in charging speed, especially for DC charging. Its additional DC pins enable significantly faster charging rates, reducing overall charging times.

1.J1772:Level 2 charging stations with j1772 connectors are prevalent across North America. However, the availability of DC fast chargers compatible with j1772 may be limited.

2.CCS:CCS infrastructure is expanding rapidly, with more DC fast chargers being deployed worldwide. This growth is driven by the demand for faster charging speeds and CCS compatibility with newer electric vehicle models.

Future Outlook

1.J1772:While j1772 remains widely used, its limitations in rapid DC charging may become more apparent as EV technology evolves. Nevertheless, existing j1772 infrastructure is expected to remain relevant.

2.CCS:CCS is positioned for the future, capable of supporting evolving EV technology. As automakers adopt CCS ports, the infrastructure supporting CCS charging is likely to expand further.


Choosing between j1772 and CCS charging standards depends on factors like compatibility, charging speed, and infrastructure availability. By understanding their differences, you can make informed decisions that suit your EV charging needs.
