Charging Rights Management

The electromobility industry is facing major challenges. Charging infrastructure providers are particularly affected: They are confronted with an asynchronous market ramp-up of infrastructure and vehicles, cost pressure due to rising installation and operating costs, a volatile funding landscape and an unstable regulatory framework.

A central problem in the economic development and operation of infrastructure is the real-time distribution of charging requirements to network capacities. Our approach to solving these challenges is coordinated charging planning, which enables a dynamic distribution of demand to supply in depots and at public and semi-public charging stations. This allows charging processes to be optimised for the grid and operations, thereby optimising cost efficiency and operational safety in electromobility.

However, the challenges in harmonizing demand and supply are not only intensified by the market penetration of e-cars, but also by the foreseeable market adoption of e-trucks. These are vehicles that can charge at around 400 to 1000 kW and require very powerful grid connections - and the trend in charging power is towards 3000 kW.

There are also a variety of charging scenarios: From very fast high-power charging en route to intermediate charging at goods distribution centers or in depots, to slow overnight charging during rest periods. There are also special requirements for access systems, maneuvering areas and parking space monitoring, not least because there is already a shortage of around 400,000 parking spaces for trucks along Europe's transport routes.

However, the expansion of network capacities and infrastructure takes a long time and will continue to lag behind the growth in electrified vehicles. The ratio of charging points to vehicles continues to rise.

In addition, the interoperability solutions implemented to date, known as roaming, do not allow for sufficient competition. For example, spot market prices cannot be dynamically passed on to end users due to the tariff sovereignty of charging service providers (ESPs). The legislator has already created the framework conditions for a so-called pass-through model - i.e. the possibility of separating infrastructure charges from electricity costs and thus allowing more dynamism in the tariff structure. This is intended to increase the incentive and control effect of dynamic prices, i.e. price elasticity.

We therefore develop standards, interfaces to applications, middleware and a planning logic for the management of charging rights (Charging Rights Management and Policy Control) tailored to the needs of our customers. The latter allows us to translate our customers' operational requirements into requests to charging station operators and to plan charging processes in such a way that mobility is guaranteed and station operators and network operators can optimally provide the required capacities.
