What is the difference between CHAdeMO and CCS EV charging

What is the difference between CHAdeMO and CCS EV charging? There are significant differences between CHAdeMO and CCS in ev charging, which are mainly reflected in standard setting, charging characteristics, application scenarios and compatibility. Here are some comparisons between CHAdeMO and CCS:

1. Standard formulation and background

1.1、CHAdeMO：

1.1.1 Definition: CHAdeMO (CHArge de MOve) is a high-power DC fast charging standard designed specifically for electric vehicles.

1.1.2 Background: The standard was first developed by the Japan Electric Vehicle Fast Charger Association to solve the problem of charging electric vehicles during long-distance travel.

1.2, CCS:

1.2.1 Definition: CCS (Combined Charging System) is a European ev combined charging system that aims to unify AC and DC charging functions worldwide.

1.2.2 Background: This standard was jointly developed by Europe and the United States to solve the charging compatibility issues between electric vehicles of different brands.

2. Charging characteristics

2.1、CHAdeMO：

2.1.1. Charging rate: Supports charging rates up to 400kW (version 3.0), which can greatly shorten the charging time of electric vehicles.

2.1.2. Communication protocol: CAN bus is used for communication, ensuring the stability and reliability of the communication process.

2.1.3. Safety: Built-in electrical isolation, voltage detection and over-current protection functions to ensure safe charging operation.

2.2, CCS:

2.2.1. Charging mode: It is compatible with four charging modes including single-phase AC, three-phase fast AC, household DC and public fast charging station DC, meeting diverse charging needs.

2.2.2 Design principles: Maintain the stability of the AC national standard, add interfaces to be compatible with older AC connectors, and support DC charging in the same car.

2.2.3. Safety and efficiency: The concept of a combined charging connector integrates the existing AC connector, improving the convenience and efficiency of charging.

3. Application scenarios

3.1、CHAdeMO：

Mainly used in ev charging stations in Japan and some European markets.

Ideal for long journeys or when charging is needed urgently, as it can provide large amounts of power quickly.

3.2 CCS:

Mainly used in ev charging stations in North American and European markets.

Suitable for various charging scenarios, including home charging, public charging stations, and long-distance travel charging.

4. Compatibility

4.1、CHAdeMO：

Proprietary interface, not compatible with other charging standards.

This means that electric vehicles using the CHAdeMO interface cannot be directly charged using charging piles of other standards.

4.2 CCS:

Committed to unifying various charging interfaces and improving compatibility.

It is compatible with multiple charging modes, allowing electric vehicles from different brands and regions to be charged on the same charging pile.
