ISO 15118 Under the Hood: The Cryptography and PKI Trust Architecture Behind Plug & Charge

Behind the convenience of Plug & Charge lies a sophisticated security architecture comparable to banking systems. Moving beyond surface-level concepts, this article dives into the technical core of ISO 15118. We dissect the hybrid symmetric and asymmetric encryption mechanisms, detail the establishment of the PKI trust chain from the V2G Root CA to end devices, and interpret how the VDE-AR-E 2802-100-1 application guide builds a complete PnC ecosystem. Finally, we demonstrate how the Charge Bridge module transforms these complex low-level protocols into out-of-the-box product capabilities.

Plug & Charge Deep Dive: Simplifying the EV Charging Experience

Plug & Charge is revolutionizing the EV charging experience, but not all "plug-and-play" solutions are created equal. This article provides an in-depth analysis of the critical differences between native ISO 15118-based PnC technology and Autocharge (MAC address authentication), exploring the underlying security mechanisms and implementation challenges. Furthermore, we reveal how the Charge Bridge hardware module empowers charger manufacturers to overcome technical barriers and rapidly deploy a seamless, financial-grade payment experience.
