Full title and description

IEC TR 60784:1984 — "Instrumentation for electric road vehicles". Technical Report describing recommended types of instruments and signalling devices for battery electric road vehicles, how they may be fitted and treated. Prepared by IEC/TC 69 (Electrical power/energy transfer systems for electrically propelled road vehicles and industrial trucks).

Abstract

This Technical Report sets out guidance on instrumentation used specifically in electric road vehicles (battery-electric vehicles), excluding items that are common to vehicles with internal combustion engines. It lists kinds of indicating meters, control lights and signalling devices, and gives general requirements for their installation, protection and use. The document was published in 1984 and has since been withdrawn.

Scope

Applies to instrumentation of electric road vehicles and gives recommendations on the types of instruments and signalling devices that may be fitted, and on general requirements for their mounting, protection and treatment. The report explicitly excludes items of instrumentation used in vehicles with internal combustion engines where those items are common to both vehicle types.

Key topics and requirements

• Classification of instrument types for electric road vehicles (indicating meters, control lights, signalling devices).
• Basic requirements for installation and mounting of instrument panels and devices on electric vehicles.
• Recommendations on placement, visibility and ergonomic aspects for driver information displays and indicators.
• Guidance on protective measures (mechanical protection, environmental sealing) appropriate to vehicle service conditions.
• Marking and identification of instruments and signalling devices.
• Notes on testing, inspection and maintenance recommendations for instrumentation (general guidance rather than prescriptive test methods).
• Normative/reference status: concise technical report (original edition contains no extensive normative reference list).

Typical use and users

Used historically by electric vehicle manufacturers and component suppliers as informative guidance for specifying and installing vehicle instrumentation; referenced by engineers designing driver information systems, maintenance and test laboratories, vehicle safety assessors and by national standards bodies when developing EV-specific instrumentation guidance. Today it is mainly of historical or archival interest because it has been withdrawn.

Related standards

Other IEC technical reports from the same era addressing electric road-vehicle subsystems are closely related, for example IEC TRs covering wiring and connectors, traction motors and controllers (examples: IEC TR 60783, IEC TR 60785, IEC TR 60786 and other TC 69 publications). More recent standards and series that address modern EV systems include IEC standards on EV charging and vehicle electrical systems (for example the IEC 61851 series) and later IEC/ISO work under TC 69 and related technical committees.

FAQ

Q: What is this standard?

A: IEC TR 60784:1984 is a Technical Report titled "Instrumentation for electric road vehicles" published by the International Electrotechnical Commission (IEC) in December 1984. It provided guidance on instruments and signalling devices for battery electric road vehicles.

Q: What does it cover?

A: It covers the kinds of indicating meters, control lights and signalling devices appropriate to electric road vehicles and gives general recommendations on how they should be fitted, protected and treated. It excludes instrumentation items common to internal combustion engine vehicles.

Q: Who typically uses it?

A: Historically it was used by EV manufacturers, component suppliers, vehicle systems engineers, test laboratories and standards developers. After withdrawal it is primarily of historical or reference interest.

Q: Is it current or superseded?

A: The report was withdrawn (withdrawal recorded by IEC) on 15 September 2016. IEC does not list a direct one-for-one replacement; national bodies have noted the withdrawal and practitioners now rely on more recent EV-specific IEC and ISO publications and national regulations for current requirements.

Q: Is it part of a series?

A: It formed part of a set of 1980s IEC technical reports produced by TC 69 that addressed various subsystems of electric road vehicles (examples include TRs on wiring/connectors, controllers and rotating machines). It is not a multi-part standard series in the modern sense but is related to those contemporaneous TRs and later IEC work on EV systems.

Q: What are the key keywords?

A: Electric road vehicles, instrumentation, indicating meters, control lights, signalling devices, IEC TR 60784, vehicle instrumentation guidance, withdrawn standard.
