The Difference Between CCS Type 1 and Type 2

Introduction:

The use of electric vehicles (EVs) is rapidly increasing as more people are looking for sustainable transportation options. However, to meet the demand, it is crucial to have a reliable charging infrastructure in place. The Combined Charging System (CCS) is one such standard that allows for fast charging of EVs. There are two types of CCS connectors available – Type 1 and Type 2. In this article, we will explore the differences between these two types.

Type 1:

Type 1 CCS connectors, also known as SAE J1772, are primarily used in North America and Japan. They feature a five-pin design and can deliver up to 240 volts of power. This type has been widely adopted by many automakers, making it compatible with various electric vehicle models. However, one drawback of Type 1 connectors is their relatively slower charging speed compared to Type 2.

Type 2:

Type 2 CCS connectors, also known as IEC 62196-2, are commonly used in Europe. They employ a seven-pin design and can handle both single-phase and three-phase electrical currents. One significant advantage of Type 2 connectors is their ability to provide faster charging speeds compared to Type 1. Moreover, they offer additional functionalities such as communication between the charging station and the EV, allowing for real-time data exchange.

Differences:

- Power Output: While both Type 1 and Type 2 connectors support alternating current (AC) charging, Type 1 connectors typically provide a maximum power output of 7.4 kilowatts (kW), limiting the speed of charging. On the other hand, Type 2 connectors can deliver higher power outputs, up to 43 kW or even more with three-phase charging, enabling faster charging times.

- Geographical Distribution: Type 1 CCS connectors are predominant in North America and Japan, while Type 2 CCS connectors are widely used in Europe. This difference in geographical distribution means that EV owners need to consider the availability of charging infrastructure when buying an electric vehicle.

- Communication Functionality: Type 2 connectors offer enhanced communication capabilities between the EV and the charging station. This allows for features like smart charging, where the vehicle and the charging point can exchange information to optimize charging speed and efficiency. Type 1 connectors, while still reliable, do not have the same level of communication functionality.

In conclusion, the choice between Type 1 and Type 2 CCS connectors depends on various factors, including the region where the EV will be used and the desired charging speed. Understanding these differences will help electric vehicle owners make informed decisions and ensure a seamless charging experience.
