Electric vehicles (EVs) are transforming how we think about transportation, and with this shift comes new technology—especially in how we charge. Among the most common charging connectors in North America are SAE J1772 and CCS (Combined Charging System). While they may look similar, they serve different purposes and offer different charging experiences. This article will walk you through the core differences, benefits, and what you should consider when choosing between the two.
J1772, also known as SAE J1772, is the standard AC charging connector used for Level 1 and Level 2 charging. It’s the default connector on most public charging stations and residential chargers in North America.
Charging Type: AC only
Range: Up to 19.2 kW
Best for: Home charging, workplace charging, and daily top-ups
Used by: Nearly all non-Tesla EVs in North America, including Nissan, Chevrolet, and Toyota
This connector is widely adopted and reliable for overnight charging or regular daily use.
CCS stands for Combined Charging System, and it builds upon the J1772 design by adding two extra pins for DC fast charging. The full CCS connector allows for both AC (via the J1772 portion) and DC charging (via the extra pins below).
Charging Type: AC and DC
Power Range: Up to 350 kW (DC fast charging)
Best for: Long-distance travel, highway rest stops, and fast charging on the go
Used by: Ford, Volkswagen, BMW, Hyundai, GM, and others
CCS is the connector of choice for fast public charging networks, including Electrify America and EVgo.
| Feature | J1772 | CCS (Combo) |
|---|---|---|
| Charging Method | AC only | AC + DC fast charging |
| Power Output | Up to 19.2 kW (Level 2) | Up to 350 kW (DC) |
| Charging Speed | Slow to moderate | Fast |
| Use Case | Home, work, daily use | Highway, commercial use |
| Connector Pins | 5 | 7 (adds 2 DC pins) |
| Compatibility | AC chargers only | AC + DC chargers (backward compatible with J1772) |
If you primarily charge at home or at work, J1772 is more than enough. It's convenient, cost-effective, and gentle on your battery. Most Level 2 home chargers use this standard.
If you often take long road trips or depend on public fast charging, CCS is essential. It can charge your vehicle in as little as 15–30 minutes, depending on your EV and charger capacity.
In North America, Tesla uses a proprietary plug, but Tesla vehicles come with a J1772 adapter and now support CCS charging with the appropriate adapter. Tesla is also opening up Superchargers to non-Tesla EVs with CCS ports in select regions.
Both J1772 and CCS play critical roles in the EV charging ecosystem.
J1772 is perfect for everyday, routine charging.
CCS offers the high-speed charging needed for longer trips and quick turnarounds.
understanding the differences between J1772 and CCS connectors empowers EV owners to make smarter charging choices—whether for daily commutes or long-distance travel. As EV infrastructure continues to grow, knowing which plug fits your needs ensures a smoother, faster, and more convenient electric driving experience.
