What Is The Difference between J1772 And CCS?

Electric vehicles (EVs) are changing the way we think about transportation. As more people make the switch to EVs, understanding charging options becomes crucial. Two prominent charging standards, J1772 and CCS, play a key role in ensuring fast, efficient charging. Knowing the differences between these standards can help both EV owners and fleet operators choose the right solution for their needs. In this post, we’ll explain the differences between J1772 and CCS, and how choosing the right EV charger adapter can improve your charging experience. We’ll also highlight how EVTAURUS offers a wide range of adapters, ensuring compatibility for both residential and commercial markets.

What is an EV Charger Adapter?

An EV charger adapter is a device that allows electric vehicles (EVs) to connect to different types of charging stations. It acts as a bridge between your vehicle and the charging infrastructure, ensuring compatibility across various standards.

How Do EV Charger Adapters Work?

EV charger adapters work by matching the specific plug type of your vehicle with the charging station. For instance, a J1772 adapter allows vehicles with a different connector to use a standard charging station, while a CCS adapter enables compatibility with high-speed DC charging systems. These adapters ensure the safe and efficient transfer of power to your EV, regardless of the charging standard.

Why the Right EV Charger Adapter Matters

Choosing the right EV charger adapter is crucial for smooth and effective charging. With a variety of vehicle types and charging stations available, an incompatible adapter could slow down charging speeds or even prevent your vehicle from charging altogether. Ensuring you have the correct adapter will help maximize convenience and maintain the health of your vehicle’s battery.

What is J1772?

The J1772 standard, also known as the SAE J1772, is one of the most widely used charging connectors for electric vehicles (EVs). It is designed for safe and reliable connections between EVs and chargers, ensuring efficient power transfer.

History and Development of the J1772 Standard

The J1772 standard was developed by the Society of Automotive Engineers (SAE) to establish a universal connector for electric vehicle charging. Introduced in the early 2000s, it quickly became the industry standard in North America for Level 1 and Level 2 AC charging. The aim was to create a simple, widely compatible, and safe solution for both home and public charging.

Types of EVs That Commonly Use the J1772 Connector

Most electric vehicles on the market, especially older and standard models, use the J1772 connector. This includes popular EV brands like Nissan, Chevrolet, and Ford. These vehicles typically rely on Level 2 charging for faster home charging.

Specific Uses of J1772 in Home and Public Charging Stations

J1772 is primarily used in home charging stations and public Level 2 chargers. For home installations, it's an affordable option for EV owners looking to charge their vehicles overnight. Public chargers also widely adopt J1772 for its accessibility, offering widespread availability in cities and highways.

Key Features of J1772 Connectors

• Single-phase charging: J1772 connectors support single-phase AC charging, typically up to 240 volts.

What is CCS (Combined Charging System)?

The CCS (Combined Charging System) is a standardized fast-charging technology for electric vehicles (EVs), providing a powerful and efficient way to recharge both passenger and fleet vehicles. It's designed to support higher charging speeds, offering both AC and DC fast-charging capabilities.

History and Development of the CCS Standard

The CCS standard was developed as a collaboration between major automakers, including BMW, Daimler, and Volkswagen. Introduced in the early 2010s, it was designed to address the limitations of previous charging standards like CHAdeMO. The goal was to create a universal connector that supports both AC and DC charging for a wide range of EVs.

Types of Vehicles Using CCS Connectors

CCS connectors are primarily used in newer EV models, including many from manufacturers like Tesla, BMW, and Chevrolet. Fleet vehicles are also widely equipped with CCS connectors, allowing them to take advantage of the high-speed DC charging infrastructure. The rapid adoption of CCS is driven by its ability to handle fast charging, making it ideal for long-range EVs and high-usage fleets.

Uses of CCS in Public Fast-Charging Infrastructure

CCS is commonly used in public DC fast-charging stations, offering quick and efficient charging, especially on highways and busy urban areas. It's the go-to charging solution for commercial and long-range electric vehicles that need to recharge quickly during long trips. The widespread adoption of CCS allows EV owners to access a robust and growing network of fast-charging stations.

Key Features of CCS Connectors

• Support for both AC and DC fast charging: CCS is unique in its ability to handle both types of charging, making it versatile.

• Higher power ratings compared to J1772: CCS connectors support power outputs up to 350 kW, significantly higher than J1772, which is typically limited to 19.2 kW.

• Compatibility with Level 3 charging stations: CCS is designed for use with DC fast chargers (Level 3), enabling rapid charging in as little as 30 minutes.

Common Myths About J1772 and CCS

Clarifying Misconceptions About the Limitations of J1772

A common myth is that J1772 can’t charge EVs fast enough. This is not true. While J1772 is primarily used for Level 2 AC charging, it still provides a solid charging speed, especially for residential use. Many people assume it’s slow, but it can deliver up to 19.2 kW for EVs that don’t require faster DC charging. For daily driving, this speed is more than enough for most users.

Debunking Myths About CCS Being Incompatible with Older EVs

Another misconception is that CCS is only compatible with newer EVs, leaving older models out of the equation. In fact, CCS is designed to be backward-compatible. Some older EVs can use CCS for faster charging, though they may require an adapter or specific updates. CCS connectors also support DC fast charging, which is why they’re mostly used in newer vehicles equipped for faster charging speeds.
