Introduction of boost current for EV DC Charging
The CharIN whitepaper "Introduction of Boost Current for EV DC-Charging" proposes a framework for utilizing short-term boost current to enhance EV fast-charging speeds while ensuring safety and interoperability. It defines key parameters such as Rated Boost Current (IRBC), Boost Duration (ΔtRBC), and Cooling Down Duration (ΔtRCD) to regulate thermal management and prevent overheating. The paper outlines a certification concept based on international standards (IEC 62196 & IEC 61851) and introduces an enhanced temperature rise test for cable assemblies. Additionally, it advocates for integrating boost current operation into global EV charging standards by 2030, with a proposed temporary IEC document as an interim measure to facilitate adoption.

ACER’s amendment proposals for the European Grid Codes
This document offers a brief overview for those who may not be familiar with the role of electric vehicles (EVs) in Europe’s electricity grids, specifically highlighting the requirements for generators (RfG) as part of ACER’s proposal. With the rising number of EVs, challenges such as load peaks and grid instability arise, but they also present opportunities for better management of renewable energy. European lawmakers have assigned the Agency for the Cooperation of Energy Regulators (ACER) the task of revising the Grid Codes to create standardized connection requirements for EVs and electric vehicle supply equipment (EVSE). The proposed modifications aim to improve grid stability and facilitate vehicle-to-grid (V2G) systems, which can provide crucial services like frequency regulation. If these updates receive approval, they are anticipated to be implemented by the end of the decade.
