This whitepaper by smartEn outlines a strategic roadmap for integrating electric vehicles (EVs) into Europe’s power system to accelerate decarbonization and enhance grid flexibility. It identifies five key priorities—grid interaction, aggregation, infrastructure cost reduction, EU-wide harmonization, and taxation reform—to unlock the full potential of EVs as dynamic energy assets. With policy recommendations for EU institutions and member states, the paper advocates for smart charging, vehicle-to-grid capabilities, and regulatory alignment to support a sustainable and consumer-friendly e-mobility ecosystem.
