Mobility

Electromobility represents an innovative leap forward that requires a new, overarching systems approach. In order to position the German economy successfully in terms of mobility, it is important to exploit the positive effects yielded by standards right from the start of the development process in order to make full use of them.

What is the aim of standards in the field of mobility?

Icon bitte beachten

Mobility standardization lays the foundations for a successful upsurge in the electromobility market. Mobility in the future will be: flexible, ecological, efficient. The solution: networked, electric, autonomous. Nowadays, the intelligent networking of completely diverse sectors and means of transport is more important than ever. Mobility now covers a wide range of industries and technologies, such as automotive engineering, electrical and power engineering, information and communication technology. Standards provide the necessary compatibility, interoperability and – above all – safety in the various mobility systems necessary for creating an integrated mobility experience for users.

However, perhaps the most decisive criterion for the market success of e-mobility is its user-friendliness. Electromobility must be economical and suitable for everyday use – for providers and users alike. Only if the technological accessibility is simple, intuitive and standardized, and if the customer has clear added value, will e-mobility become a success story. This is precisely where standardization is needed. The goal is to create a smart form of mobility that is future-proof in an environmentally friendly and efficient way.

What is the focus of mobility standards?

Smart mobility is gaining in significance. It is opening up new areas such as Car2Car and Car2Infrastructure communication which have arisen as a result of increased traffic safety requirements and the integration of electric vehicles into the intelligent energy network (smart grid). Standards are indispensable, particularly for the interlinking of the energy, mobility and information technology (ICT) sectors.

Charging an e-vehicle presupposes the existence of a suitable infrastructure. Standards lay down important rules for this. Only standardized charging plugs and systems, wired and wireless, ensure interoperability between different manufacturers, which in turn can create an upsurge in the e-mobility market. Standards support the establishment of a Europe-wide and internationally uniform charging infrastructure with standardized charging and connector systems. Standards specify efficient billing systems which in turn ensure uniform billing processes.

The resulting high level information and data flows in the smart grid represent an inviting target for abuse. Standards create a basis for data security and data protection here. They provide investment security, ensure interoperability and open up the market – an aspect of great importance today. Electromobility will only be successful if it is standardized worldwide. The latest trends and current developments in the field of mobility are engendering new ways of thinking and giving rise to questions that need to be addressed.

Icon Frage und Antwort

What everyday benefits do we have from mobility standards?

Icon Frage und Antwort

Standards also play an important role in everyday life. In electromobility in particular, we have succeeded in giving consumers a uniform charging standard for both direct and alternating current charging. All new charging stations are thus equipped with a Type 2 plug for AC charging in the 3.7 kW, 11 kW, 22 kW and 44 kW power classes. In addition, the Combined Charging System (CCS System) has become established for DC charging with high charging capacities. Standardized CCS in particular is now established in Europe, the USA, Korea and other automotive markets. Disparate plugs and incompatible charging stations are a thing of the past thanks to the directives and regulations. In future, no exceptions will be allowed in systems designed for public use.

Expand your horizons: IT security in electromobility

What is the aim of IT security for electromobility standards?

Icon bitte beachten

In the future, electric vehicles will communicate extensively with their environment. In the charging and billing process in particular, energy will be transferred but so, too, will significant amounts of data. Ensuring adequate IT security is of great importance: on the one hand, acceptable levels of data protection must be ensured for personal data that is collected, processed and communicated between the parties involved in the charging and billing process. On the other hand, a large number of electric vehicles must in future also be viewed as an integral part of the critical "energy" infrastructure. "Energy" is a central critical infrastructure which, in the event of a failure or disruption, has an extreme and direct impact on the other critical infrastructures and thus on the state, economy and society. If the charging infrastructure, involving large numbers of connected electric vehicles, is compromised, synchronous load shedding or consumption can have a devastating effect on the power grid.
The challenge is to enable interaction between the "automotive" and "power supply" industries involved. Only in this way can appropriate IT security levels be achieved and implemented. The aim of IT security standards for electromobility is thus to ensure cross-sector communication and to accord IT security the level of importance necessary for giving a decisive boost to electromobility and the digitalization of the energy transition. Only if standardized IT security can render electromobility sustainable and a safe investment can it establish itself permanently and make a positive contribution to Germany as an industrial location and export nation.

International standardization has already succeeded in creating a basis for the exchange of information between electric vehicles and the charging infrastructure in the current version of the ISO 15118 standard. To protect communication, the standard recommends the use of a PKI (Public Key Infrastructure), but does not specify how it should be implemented. The DKE has created a pre-standard document that fills this particular gap. The VDE application guide VDE-AR-E 2802-100-1 "Certificate handling for electric vehicles, charging infrastructure and backend systems in the context of the use of ISO 15118" describes how a PKI should be implemented. It contains requirements for operating a PKI, such as the provision, installation and withdrawal of certificates, as well as for roles that are necessary for implementing a PKI. The VDE application guide thus supports use of the "plug & charge" principle contained in ISO 15118 and ensures communication between all the relevant parties.
Communication between the electric vehicle and charging infrastructure is of decisive importance, but so, too, is that between the charging infrastructure (with connected backend and billing systems) and the supply grid. Communication has not yet been standardized in this area. German experts were responsible for initiating the IEC 63110 "Protocol for the operation of charging and discharging infrastructure for electric vehicles" series of standards. This is an international project aimed at defining a standardized protocol and communication interface for the operation of charging infrastructure.
DKE experts are also involved in the development of the IEC 63119 "Information exchange for electric vehicle roaming charging services" series of standards. This roaming process lays down how authorization, user and billing data must be exchanged between the various charging service providers. This allows drivers to use many different charging networks and value-added services, despite being contractually bound to only one provider.
The principle of "security by design" is applied in all projects, i.e. IT security is incorporated in the system approaches from the outset. Ultimately, the aim is for standardization to assist the transfer of the developed technologies to market in order to secure the long term market position of relevant users and companies in the national, European and international context.
