Combined Charging System Specification
As the world’s only open and universal charging system for electric vehicles, the Combined Charging System (CCS) technology and architecture has been enshrined in international standards. The CCS covers single-phase AC, three-phase AC and DC high-speed charging, in both Europe and the US – all in a single, easy to use system.
The illustrated Combined Charging System Specification describes the CCS’ main features, including the charging process itself as well as safety, user authentication, payment authorisation and load balancing functions. It also provides guidance as to which standards have been implemented in the system. As such, the document makes it easier for interested parties – such as carmakers and manufacturers of charging stations – to refer to the right standards documentation in the right versions when developing or upgrading their products.
The international standards implemented in the CCS can naturally be expected to evolve over the next few years. This is why the CCS Specification also enables electric vehicle and charging equipment manufacturers to review which functions are available in the CCS now and which they can expect to see, once the relevant standards have been updated and come into force. As the CCS standards evolve, backwards compatibility will be maintained with previous iterations in order to maximize simplicity ease of use and security of investment.
The CharIN e.V. works on a functional and temporal step model describing the features of CCS in the next years.
