ACLink
ACLink is a high‑speed data transmission protocol engineered to interface alternating current power delivery systems with embedded control units. The protocol was initially developed in 2012 by a European consortium of automotive and electrical engineering companies, with the goal of providing a unified communication standard for electric vehicle charging infrastructure and industrial machinery that requires real‑time control over AC power parameters. ACLink operates in the 0.8–2.5 GHz frequency band, leveraging spread‑spectrum modulation to reduce electromagnetic interference while maintaining low latency. It supports a configuration data exchange rate of up to 80 Mbps and can carry diagnostic and status information alongside power control commands, allowing for coordinated operation of power converters, inverters, and motor drives.
The architecture of ACLink incorporates a multi‑layer stack, with a physical layer based on orthogonal frequency‑division
Since its introduction, ACLink has seen deployment in commercial electric vehicle fast‑charging stations in Germany and
