GB/T 18384.2-2015Electrically propelled road vehicles -- Safety specifications -- Part 2: Vehicle operational safety means and protection against failures (English PDF)

Foreword

GB/T 18384 "Electrically propelled road vehicles - Safety specifications" is

divided into three parts.

- Part 1.On-board rechargeable energy storage system (REESS);

- Part 2.Vehicle operational safety means and protection against failures;

- Part 3.Protection of persons against electric shock.

This Part is Part 2 of GB/T 18384.

This part was drafted according to the given rules of GB/T 1.1-2009.

This Part replaces GB/T 18384.2-2001 "Electric vehicles - Safety specification

- Part 2.Functional means and protection against failures". Compared with

GB/T 18384.2-2001, in addition to editorial changes, the main technical

changes are as follows.

- Modified the scope of the standard (see Chapter 1 of Edition 2001);

- Deleted the terms and definitions defined in GB/T 19596 (see Chapter 3

of Edition 2001);

- Added the definition of "driving-enabled mode" (see 3.1);

- Added the definition of "rechargeable energy storage system" (see 3.2);

- Added the definition of "voltage class B electric circuits" (see 3.3);

- Deleted the requirements for the main switch (see 4.5 of Edition 2001);

- Modified the requirements for electromagnetic compatibility (see 4.6 of

Edition 2001);

- Modified the requirements for failure protection (see Chapter 5 of Edition

2001);

- Added the requirements for vehicle mark (see Chapter 7);

- Added the requirements for emergency response (see Chapter 8).

This Part uses redrafting method to modify and adopt ISO 6469-2.2009

"Electrically propelled road vehicles - Safety specifications - Part 2.Vehicle

operational safety means and protection against failures".

The technical differences and the reasons between this Part and ISO 6469-

1 Scope

This Part of GB/T 18384 specifies the requirements for safe operation and

failure protection against the specific danger of electrically propelled road

vehicles, so as to protect the safety of people inside and outside the vehicle.

This Part is applicable to the electrically propelled road vehicles of which the

maximum operating voltage of the drive system is class-B voltage. The electric

motorcycle and electric mopeds may refer to this Part.

GB/T 18384.1 Electrically propelled road vehicles - Safety specifications - Part

1 On-board rechargeable energy storage system (REESS) (GB/T 18384.1-

2015, ISO 6469.2009, MOD)

3 Terms and definitions

The following terms and definitions defined by GB/T 18384.1 and GB/T 19596

are applicable to this document.

The electrical component or circuit of which the maximum operating voltage is

greater than 30 V a.c. (r.m.s.) AND less than or equal to 1,000 V a.c. (r.m.s.),

or greater than 60V DC (d.c.) AND less than or equal to 1,500V DC (d.c.).

4 Operational safety

If the rechargeable energy storage system (REESS) of vehicle's drive system

can be recharged through vehicle's external power supply, and when the

vehicle is physically connected by the user to the external power supply, then

the vehicle shall not be able to move through its drive system.

When driver leaves the vehicle, and if the drive system is still in the "driving-

enabled mode", it shall indicate the driver via an obvious signal device (e.g.

sound or light signal).

5 Failure protection

It shall adopt management measures to any possible single-point failure.

It shall try to avoid or prevent the undesirable acceleration, deceleration or

reversing caused by single-point hardware failure or software failure of vehicle's

specific system and components.

6 User manual

In the user manual, it shall specially indicate the particular matters on

operational safety and failure protection of the electrically propelled road

vehicles.

7 Mark

The vehicle mark shall be consistent with the relevant laws and regulations.

8 Emergency response

The manufacturer shall provide the information about vehicle accident handling

to the safety personnel and emergency responders.
