Electrically propelled road vehicles – Safety specifications –
Part 1: On-board rechargeable energy storage systems
(RESS)
Scope
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 third edition cancels and replaces the second edition (ISO 64691:2009) and ISO 12405-3:2014, which have been technically revised.
The main changes compared to ISO 6469-1:2009 and ISO 124053:2014 are as follows:
 — test descriptions and requirements were reworked to include
specific characteristics for lithium-ion based battery systems;
 — document was reworked to become a general safety standard
for all RESS types; and
 — almost all test procedures and descriptions as given in the
previous versions of both documents have been adapted to the
latest technical developments

Electrically propelled road vehicles – Safety specifications –
Part 2: Vehicle operational
safety
Scope
This document specifies requirements for operational safety specific to
electrically propelled road vehicles, for the protection of persons inside
and outside the vehicle
This third edition cancels and replaces the second edition (ISO 64692:2009), which has been technically revised. The main changes
compared to the previous edition are as follows:
 — clarification of the single-point failure definition and related
measures;
 — improvement of the operational safety requirements for the
driving-enabled mode;
 — elimination of marking requirements;
 — clear requirements for connection of the vehicle to an external
electric power supply;
 — simplification of EMC requirements.

– Part 3: Protection of persons against electric shock
Published
International
Scope
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
.
This third edition cancels and replaces the second edition
(ISO 6469-3:2011), which has been technically revised.
The main changes compared to the previous edition are as
follows:
 — extension of pure electric shock protection to all
electric safety requirements including those against
thermal incidents;
 — introduction of definitions and requirements for new
voltage classes B1 and B2;
 — addition of specific requirements for capacitive
discharge;
 — new test specification for the isolation resistance
monitoring system; and
 — new requirements and test for touch current.
