How Does the Combined Charging System (CCS) Work? The Combined Charging System (CCS) is a universal charging method for electric vehicles (EVs). It supports both AC (alternating current) and DC (direct current) charging through a single connector.
A CCS system simplifies EV charging by providing flexibility and convenience for different charging needs. Let’s explore its working, components, advantages, challenges, and future trends.
Overview of the Combined Charging System (CCS)
Combined Charging System is an essential part of EV charging infrastructure worldwide. It combines two charging types: AC and DC—into one connector. It makes it suitable for home charging and public fast-charging stations.
CCS reduces the need for separate connectors, making it easy for EV owners to charge their vehicles anywhere. Its ability to handle both low-power and high-power charging makes it an all-in-one solution for EV users.
Types of Combined Charging System Connectors
Combined Charging System has two main versions: CCS1 and CCS2. Both connectors are designed for compatibility with different regions.
CCS1 Connector
CCS1 is widely used in North America. It is based on the Type 1 plug and includes two DC contacts for fast charging.
CCS2 Connector
CCS2 is popular in Europe and other regions. It is based on the Type 2 plug and includes DC contacts for fast charging.
Both connectors allow efficient charging while ensuring global compatibility for EV users.

Key Components of the Combined Charging System
The working of the Combined Charging System depends on several essential components. These components work together to provide efficient and safe EV charging.
Charging Connector
The Combined Charging System plug combines AC and DC charging in one. EV users can charge their vehicles at home or at fast-charging stations.
Vehicle Inlet
The EV’s inlet is designed to accept CCS connectors. This makes it compatible with both AC and DC charging.
Communication Protocol
Combined Charging System uses the ISO 15118 protocol for communication. This protocol supports advanced features like Plug & Charge, ensuring easy billing and authentication.
Charging Stations
CCS chargers are equipped for both AC and DC charging. These stations provide power levels suitable for various EV models.
How Does the Combined Charging System (CCS) Work?
The Combined Charging System work involves a seamless process to charge EVs efficiently. It uses AC or DC power depending on the type of connector.
Charging Modes
- AC Charging: The EV’s onboard charger converts AC power from the station to DC power for the battery.
- DC Charging: The station delivers DC power directly to the EV’s battery, bypassing the onboard charger.
Charging Process
- Connection: Plug the CCS connector into the EV.
- Communication: The EV and charger exchange information using ISO 15118.
- Power Delivery: The charger supplies AC or DC power based on the EV’s needs.
- Monitoring: The system monitors voltage, temperature, and charge level for safety.
- Completion: Charging stops automatically when the process is complete.
The working of the Combined Charging System ensures quick and reliable energy transfer, especially with DC fast charging.
