Detailed Standards Coverage

ISO/IEC 14543-4-303:2026 – Interoperable Communications for EVSE Chargers

Information technology — Home electronic system (HES) architecture — Part 4-303: Application protocol for electric vehicle supply equipment (EVSE) chargers and controllers

This standard sets the application-layer protocol for communications between EVSE chargers and their controllers, leveraging the Network Enhanced Communications Device (NECD) protocol. It provides crucial guidelines to foster interoperability across products from different manufacturers, making EV charging infrastructure more unified and future-proof.

The protocol operates over UDP (using IPv4 or IPv6; TCP is optional) and specifies message structure, command sequences, timeout management, and required command sets. It facilitates energy management services, remote control operations, startup routines, and fault notifications—enabling both residential and commercial settings to seamlessly integrate EVSEs into home energy systems and smart grids.

Key highlights:

• NECD protocol implementation for EVSE chargers and controllers
• Detailed definitions for message exchange, command sequencing, and property handling
• Start-up, normal, and fault handling operations for robust system management

ISO/IEC 14543-4-304:2026 – Protocol for Bidirectional EVSE Charging/Discharging

Information technology — Home electronic system (HES) architecture — Part 4-304: Application protocol for electric vehicle supply equipment (EVSE) charger and dischargers and controllers

Expanding on the foundation established in ISO/IEC 14543-4-303, this standard introduces an application-layer protocol for bidirectional communications—enabling both charging and discharging between EVSE units and their controllers. This enhancement supports technologies such as Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) energy transfer, which are pivotal for grid stability and energy efficiency.

The protocol again utilizes the NECD framework over UDP/IP, delivering definitions for command and status messaging, attribute information retrieval, and nuanced scenarios such as fault management and remote operational control. The technical content distinguishes between charger and discharger roles, ensures interoperability, and enables integration with home energy management systems and utility signals.

Key highlights:

• Complete protocol for both charging and discharging operations in EVSE systems
• Advanced support for V2G and decentralized energy marketplace roles
• Harmonized interface models for management, run-time communication, and remote control

ISO 23150-11:2026 – Logical Interfaces for Radar Sensors in Automated Driving

Road vehicles — Logical interface between sensors and data fusion unit for automated driving functions — Part 11: Radar specific interfaces

Automated driving requires seamless data flow between radar sensors and data fusion units. ISO 23150-11:2026 specifies technology-specific logical interfaces for radar sensors or clusters used in vehicles with automated driving capabilities. It formalizes the detection level interface (DLI), defining data structures for radar detection headers, measurement signals, ambiguity indicators, object classification, and signal-to-noise ratios. The standard leverages principles defined in ISO 23150-1:2026 to promote modular and semantic interface design.

The interface definitions accommodate diverse operational profiles, including mandatory and optional radar detection features, ambiguity handling (for radial velocity or angle domains), and detection status tracking. This advances the accuracy, reliability, and safety of automated driving systems by ensuring compatibility across multi-vendor radar sensors and fusion units.

Key highlights:

• Modular, technology-specific logical detection level interfaces for radar sensors
• Comprehensive coverage of detection attributes, ambiguity handling, and data qualifiers
• Aligned with the ISO 23150 sensor data fusion architecture

ISO 23150-1:2026 – General Principles for Sensor–Fusion Interfaces in Automated Driving

Road vehicles — Logical interface between sensors and data fusion unit for automated driving functions — Part 1: General information and principles

This foundational standard introduces the general architecture and modular principles for logical interfaces between environmental perception sensors and data fusion units in automated road vehicles. By providing generic templates covering different abstraction levels (feature, advanced detection, detection), ISO 23150-1 enables vendors to implement sensor fusion systems that are interoperable, scalable, and maintainable across evolving technology stacks.

Coverage includes nomenclature, architectural context, interface levels, signal groupings, and best-practice profiles for vehicle coordinate systems, sensor clusters, and detection classification. Implementation avoids prescribing electrical or raw data interfaces—focusing solely on logical, algorithm-friendly communication.

Key highlights:

• Universal, modular templates for all types of perception sensor interfaces (radar, lidar, camera, etc.)
• Semantic data modeling for flexible system integration
• Industry baseline for all subsequent ISO 23150 sensor interface standards

ISO 23150-12:2026 – Lidar Sensor Logical Interfaces for Automated Driving

Road vehicles — Logical interface between sensors and data fusion unit for automated driving functions — Part 12: Lidar specific interfaces

As lidar technology becomes central to automated driving, standardized logical interfaces are vital for consistent system integration and vendor neutrality. ISO 23150-12:2026 specifies technology-specific logical interfaces for lidar sensors or clusters. Like its radar counterpart, it defines detection level interface (DLI) protocols, providing structured communication for measurements, detection attributes, ambiguity profiles, and error models.

The standard directly references the semantic, modular guidelines of ISO 23150-1 and scopes out both feature level interface (FLI) and advanced detection level interface (ADLI) for lidar deployment scenarios. The aim is to enhance the reliability, safety, and interoperability of lidar-based environmental sensing in complex driving environments.

Key highlights:

• Detection level interface specifically structured for lidar data streams
• Profiles to support unique lidar measurement and ambiguity characteristics
• Supports robust data fusion and high-level semantic scene interpretation
