Pre-Normative Research and foreseeable Regulatory Necessities for Future Charging Infrastructures
Dr.-Ing. Harald Scholz (Key Speaker), European Commission's Joint Research Centre

The laboratory tandem of Argonne National Laboratories (U.S. D.o.E.) and Joint Research Centre (E.C.), with their "Transatlantic Interoperability Centre for Electric Vehicles and Smart Grids", engage cooperatively in pre-normative research for, inter alia, future charging infrastructures. The new laboratory capacities are presented. Priorities in pre-normative testing and smart grid integration are reported as per the last October 2016 meeting between our laboratories and car industry at Argonne. Surrounding efforts from U.S.-federal / EU research programmes and policy departments' initiatives regarding future charging and interoperability needs are shortly summarized. Specific attention is put on issues, where our pre-normative research efforts in collaboration with EV industry, measurement device producers, EVSE producers, and grid operators lead to concrete input to current standardisation efforts globally as well as future legislation.

High Power Charging, more than a charger: modular and integrated solutions
Johan Peeters, ABB

While 50 kW fast chargers could be connected to the available grid easily, high-power chargers, starting at 150 kW and growing to higher levels in the coming years, require a more sophisticated vision on modular incremental or integrated installations, including grid power distribution, investment strategies, etc. In close cooperation with car makers and key operators, ABB develops different high-power charging roll-out strategies.

High Power Charging – more than a thermal challenge
Michael Zeyen, vancom GmbH & Co. KG

Without any question HPC is a breakthrough technology with regard to future customer expectations. But it's much more than just a further increase of the electrical power – it's a system based approach which impact all components from grid connection up to the cell contacts. Besides all the communication and software demands there is a fundamental requirement: The safety management of the electrical and in particular the thermal power.

High Power Charging (HPC) & Home Charging - Grid Effects - Status and Outlook for the US
Richard Scholer, FCA US LLC

High Power Charging (HPC) is a "game changer" to the electrification landscape from an OEM to utility perspective.This provides an opportunity for Battery Electric Vehicles (BEV) to more appealing to a broad range of customers since they will be able to improve their usage expectations that are experienced today for gasoline vehicles (e.g. cost and complexity of PHEV and FCV may become less appealing).HPC is staged to sprinkle our landscape with new products and opportunities to enable longer range travel for BEVs. HPC also effects short range travel or daily commutes, since these vehicles may or may not need charging every day, or every opportunity as today. Extended charge times at homes may also be a result of HPC vehicles, that highlights the need for Home Energy Management solutions (e.g. a BEV may only charge once a week for a 10-12 hour continuous load to the grid, instead of daily for 1-2 hours).

Beyond the EVSE - A look at grid integration
Barry Sole, Porsche AG

Major strides have been made with respect to the standardization and testing of charging infrastructures. ISO15118 continues to move us closer towards absolute interoperability and plug ’n play, but what about beyond the charging infrastructure? With a large portion of charging expected to take place in private environments, such as at home, how could the EV and EVSE integrate into Smart Homes, Energy Management Systems and Smart Grids? What protocols are need and how compatible to ISO15118 do they need to be? During this presentation we’ll take a look at these issues and explore possible solutions.

Introducing Hardware Security Modules to Embedded Systems for Electric Vehicles charging according to ISO/IEC 15118
Fabian Eisele, Vector Informatik GmbH

The ISO/IEC 15118 is using X.509 certificates for the automated authorization of vehicles at the charging station. Because of this, personal and especially confidential information has to be stored in the vehicle. To protect this data from unauthorized access and to unload the host controller from calculating cryptographic operations, Hardware Security Modules (HSM) are introduced. They're able to secure certain areas of the memory and can execute required operations like the creation of signatures or encryption of data in a protected environment. This talk gives an overview about the certificate infrastructure of the ISO/IEC 15118 and the resulting requirements to an HSM.

Requirements towards the “System” (OEMs, EVSE suppliers, Standards, Utilities) to enable a sustainable business for the CPOs
Dr. Stephan Hell, Allego GmbH

Future charging station concepts see a lot of requirements which need to be fulfilled in order to secure an easy, safe and reliable operation. These requirements cover demands from grid utilities, expectation towards the EVSE supplier, use case definition from the OEM and MSP and legal regulation from national authorities. Since especially high power charging stations are a high investment with requirements and expectations and as the role of a CPO is the aggregator of all the interest and specs it has to make quite sure that there are standardized and synchronized specifications available to have a common understanding of the business case and the use cases.

Current standardization situation as well as technical challenges in EMC testing of electric vehicles in charging mode
Dipl.-Ing. Marc Maarleveld, EMC Test NRW GmbH

Electric vehicles are gaining in importance and acceptance both in engineering sciences and in the population, but also imply a number of new challenges and constraints with regard to technical requirements. Thus, the charging process of an EV represents a completely new operating state, which is not used in conventional engines with an internal combustion engine. This results in completely new requirements for EMC, which must now be taken into account. The presentation deals with these new requirements and the resulting challenge in implementation.

Roadblocks on the Way to a Globally Harmonized Wireless Power Transfer Standard
Samuel Kiefer, Kiefermedia GmbH

It is not a trivial pursuit to standardize an invisible interface. In the meantime there is a convergence path visible on the agendas of several standardization bodies, yet. This is a more abstract and generic approach than the construction manuals seen before, but there are roadblocks on an unexpected level of common sense.
