Study 4

Ensuring readiness for and compatibility with future requirements

Introduction

Since the electric transport sector is still in an early phase of innovation, the vehicle and charging infrastructure landscape of the future will very likely look different from the charging solutions and vehicle technology that are currently in the market. Keeping this in mind, the pilot network that is deployed in the fast-E project should be prepared for future technology developments. The base for future readiness is ensured by the use of the latest standards, and the use of equipment that allows upgrades to the next generation of standards. Looking further ahead, certain technologies will most likely affect future requirements for fast charge solutions. In order to get a better outlook and to be prepared for these future requirements, study 4 will examine two key technological developments from a technical and business perspective. The two topics evaluated are the integration of battery energy storage at fast charging locations (4.1) and high power charging (4.2).

Objective as stated in Grant Agreement:

Studying technological development and future charging requirements, testing the potential of stationary storage with used EV batteries to increase grid connection efficiency and prepare larger-scale integration of renewable energy in the charging network.

Overarching question:

How can energy storage and high power charging contribute to future development of the fast charging network, and which steps should be taken in order to align and properly prepare for the impact of these future technologies?

This question will be addressed in sub-study 4.1 and 4.2

Sub-study 4.1 Stationary Storage and Renewable Energy Integration

Sharp costs reductions for energy storage in batteries have pushed developments in electric transport and have raised expectation for enlarged integration of renewable energy. This study combines these developments in order to get an outlook on the future potential for integration of energy storage in the fast charging network and to explore the possibilities for the use of 2nd life batteries.

Sub-study 4.2 Evaluation of High Power Charging Requirements

The development of EV charging technology is progressing, and as battery density and size increases, new charging opportunities arise, beyond the common fast charging level of 50kW. The consortium partners will build on readily available research into ultra-fast charging technologies (>100kW) to examine technical requirements (e.g. vehicle design, site configuration, network planning, and grid connection) and business impact in a longer term perspective.

In order to examine these elements, the technical knowledge and experiences from the OEMs and CPOs involved will be bundled. These experiences feed into a nationally funded project by means of which 18 locations of the fast-E (DE/BE) network will be prepared for High Power Charging (150kW) solutions. This existing knowledge along with the experiences in the preparation deployment phase will be used in order to come up with joint set of recommendations.
