Are Vehicle to Grid spikes coming?

This piece examines the security, privacy, and operational risks of Vehicle-to-Grid (V2G) and demand-side response (DSR) in the EV ecosystem, highlighting weaknesses and implementation challenges in emerging standards (e.g., ISO/IEC 15118, DIN Spec 70121), the threat of aggregated charger control and tariff-driven load cliffs causing grid instability, potential OEM-driven battery control and ethical concerns, and the need for robust authentication and rigorous validation to prevent data exposure, battery degradation, and possible blackouts.
