ISO/TC 23/SC 19/WG 9 - Components and electrical systems

This document specifies the communication interface, so that the transmitted parameters, signals and objects between a supply system (SS), with power converter/switch (PC/S) and high power interface – master control (HPI-MC) including the tractor implement management (TIM) server, and a consumer system (CS), with application (APP) and high power interface – control (HPI-C) including the TIM client and the task controller, can be used is in the agricultural industry. The mentioned signals are used during identification, initialization, operation, and shutdown modes of operation. This document does not cover the definitions of suspect parameter numbers (SPNs) for the signals, within the parameter group numbers (PGNs) for messages and the message setup. These definitions are given in ISO 11783 and SAE J1939. NOTE For information on messages (PGNs) see also Annex B.

This document specifies measures applicable to the class B2 voltage DC bus of a supply system which is intended to power detachable electrical CS(s). - electrical specification of the high power interface - operating modes (e. g. initialization, normal operation, energy feedback, connect/disconnect procedures and disconnect in case of malfunction) - Communication parameters (basic framework: signals, ranges, units, states of supply system and CS) The document contains simplified electrical diagrams showing specific aspects of the required functionality.

This document specifies direction for the design of the physical interface between a supply system and a consumer system. Electrical, geometrical and test requirements are defined within this document.

This document specifies required measures applicable to the HPI AC Interface between a supply system (typically located on an agricultural tractor) and detachable electrical consumer system (typically located on an agricultural implement). This document covers the following: - HPI system topologies; - interface relevant characteristics of the HPI providing AC or combined AC and DC; - interface relevant characteristics of the HPI AC load (for relevant characteristics of a DC load, see ISO 23316‑5); - logical, operational and electrical characteristics of the HPI: - operating mode aspects, and - communication parameters NOTE This document contains simplified electrical diagrams showing specific aspects of the required functionality.

This document describes the general safety requirements and guidance for the electrical high-power interface (HPI) in the ISO 23316 series. The following topics are not within the scope of this document: - service, maintenance, and related diagnostics; - functional safety; - control strategies for high power supply systems (PS) and load consumption systems; - application-specific strategies and operational modes; - component design; - energy storage systems, e. g. supercapacitors or batteries; - multiple electrical power supplies to a common DC-link.

This document instructs the manufacturers of tractors and implements how to integrate mechanically and use the HPI. NOTE The terms "tractor" and "implement” are used instead of “supply system” and “consumer system” for better understanding in this part.

This document describes the general purpose and structure of the ISO 23316 series and common elements of the ISO 23316 series. The following topics are not within the scope of this document: - service, maintenance, and related diagnostics; - functional safety; - control strategies for high-power supplies and loads; - application-specific strategies and operational modes; - component design; - energy storage systems, e. g. supercapacitors or batteries; - multiple electrical power supplies to a common DC-link.
