Electrically Propelled Vehicles

This International Standard specifies the procedures for measuring the road performance of purely electrically propelled passenger cars and commercial vehicles of a maximum authorized total mass of 3 500 kg1_. The road performance comprises road operating characteristics such as speed, acceleration and hill climbing ability.

This International Standard specifies test procedures for measuring the reference energy consumption and reference range of purely electrically propelled passenger cars and commercial vehicles of a maximum authorized total mass of 3 500 kg and maximum speed greater than or equal to 70 km/h.

Establishes a vocabulary of terms and the related definitions used in ISO/TC 22/SC 21 standards specific to the electric propulsion systems of electrically propelled road vehicles, i.e. battery-electric vehicles (BEV), hybrid-electric vehicles (HEV, PHEV), and fuel cell vehicles (FCV, FCHEV).

ISO 6469-4 specifies safety requirements for the electric propulsion systems and conductively connected auxiliary electric systems of electrically propelled road vehicles for the protection of persons inside and outside the vehicle. It specifies electrical safety requirements for vehicle post-crash conditions. It applies to electrically propelled road vehicles with voltage class B electric circuits.
It does not apply to motorcycles and mopeds. It does not specify any crash test procedure. The safety requirements of this part of ISO 6469-4:2015 apply to applicable vehicles in accordance with published crash test procedures of each country or region. Applicable vehicles are those vehicles which are explicitly specified in these crash test procedures. It does not provide comprehensive safety information for first responders, emergency services, maintenance, and repair personnel.

This document specifies electrical safety requirements for voltage class B electric circuits of electric propulsion systems and conductively connected auxiliary electric systems of electrically propelled road vehicles. It specifies electrical safety requirements for protection of persons against electric shock and thermal incidents.It does not provide comprehensive safety information for manufacturing, maintenance and repair personnel.

ISO 6469-2 specifies requirements for operational safety specific to electrically propelled road vehicles, for the protection of persons inside and outside the vehicle.

This document specifies safety requirements for rechargeable energy storage systems (RESS) of electrically propelled road vehicles for the protection of persons.
It does not provide the comprehensive safety information for the manufacturing, maintenance and repair personnel.

This document specifies safety requirements for rechargeable energy storage systems (RESS) of electrically propelled road vehicles for the protection of persons.

It does not provide the comprehensive safety information for the manufacturing, maintenance and repair personnel.

NOTE 1 Requirements for motorcycles and mopeds are specified in ISO 13063 and ISO 18243.

NOTE 2 Additional safety requirements can apply for RESS that can be recharged by means different from supplying electric energy (e.g. redox flow battery).

ISO 23274-2 specifies a chassis dynamometer test procedure to determine the end of CD (charge-depleting) state and consumed electric energy during CD state. The identification of the end of CD state is an important step for procedures to determine exhaust emissions and fuel consumption. Final determination of exhaust emissions and fuel consumption is not included in ISO 23274-2. ISO 23274-2:2012 applies to vehicles with the following characteristics. The vehicles are hybrid-electric road vehicles (HEV) with an internal combustion engine (ICE) and the on-board rechargeable energy storage system (RESS) for vehicle propulsion which is supplied by electric energy from the stationary external power source. A CD state, in which the electric energy in RESS from the stationary external power source is consumed, is followed by a CS (charge-sustaining) state in which the fuel energy is consumed sustaining the electric energy of the RESS. Only batteries are assumed as the RESS of a vehicle. The RESS is not charged while driving unless by regenerative braking and/or by generating by ICE. The vehicle is classified as a passenger car or light duty truck, as defined in each regional annex.
Only liquid fuels (for example, gasoline and diesel fuel) are used. Trolleybuses and solar powered vehicles are not included in the scope. In the case of vehicles with ICE using other fuel [for example, compressed natural gas (CNG), hydrogen (H2)], ISO 23274-2:2012 can apply except the measurement of consumed fuel; otherwise the measurement method for those using the corresponding fuel can apply.
