3.1 Terms and Definitions

The terms and definitions defined in GB/T 19596, GB/T 32960.1, GB/T 32960.2, GB/T 32960.3, and GB 38031, as well as the following terms and definitions, are applicable to this document.

3.1.1 Platform data of new energy vehicle safety operation

Data obtained through the on-board terminals of new energy vehicles and stored on the public service and management platform as well as the enterprise service and management platform that reflects the operational safety status of new energy vehicles.

3.1.2 Public service and management platform

A platform established by the national or local governments or their designated agencies for the data acquisition and centralized management of new energy vehicles within their jurisdiction.

3.1.4 Dynamic monitoring

Using platform data of new energy vehicle safety operation or data models to conduct real-time or near-real-time monitoring and analyze operational safety faults or potential hazards.

NOTE 1.Operational safety faults may cause situations where electrical safety components or systems unique to new energy vehicles (such as traction batteries, drive motors, and electronic control systems) fail to meet design operating conditions during operation.

NOTE 2.Operational safety potential hazards may cause damage or threat to the electrical safety components or systems unique to new energy vehicles (such as traction batteries, drive motors, and electronic control systems).

3.1.5 Dynamic early warning

Using the results of dynamic monitoring of new energy vehicle safety operation to issue risk notifications or alerts to new energy vehicles that have operational safety faults or potential hazards.

5.1 Fault Monitoring

5.1.1 Monitoring items

Fault monitoring items shall include the contents listed in Table 1.

Table 1 -- Operational Safety Fault Monitoring for New Energy Vehicles 5.1.2 Monitoring shall be conducted in accordance with the following procedures.

a) Extract the generic alarm flag data from Table A.1 based on the fault monitoring items listed in Table 1;

b) Analyze the data using the generic alarm flag bits specified in Table A.6 to generate monitoring results for the item;

c) When the monitoring results from the enterprise service and management platform indicate an abnormality, report the monitoring results in real-time; the format and definition of the reported data shall comply with the requirements of Table B.2.

5.2 Potential Hazard Monitoring

5.2.1 Monitoring items

Potential hazard monitoring items shall include the contents listed in Table 2.

Table 2 -- Operational Safety Potential Hazard Monitoring for New Energy Vehicles indicate an abnormality, the results shall be fed back in real time; the format and definition of the fed-back data shall comply with the requirements of Table B.7.

6.1 General Requirements

6.1.1 It shall be capable of issuing fault notifications and potential hazard alerts based on dynamic monitoring results.

6.1.2 Dynamic early warning and handling measures shall be formulated based on factors such as operational safety fault levels and the frequency of potential hazards; the content of these measures is detailed in Appendix D.

6.2 Fault Notifications

6.2.1 Fault notifications shall be issued according to a tiered system comprising three levels.

Specifically. Level 1 faults are those that do not affect the vehicle’s normal operation; Level 2 faults are those that affect vehicle performance and necessitate restrictions on speed, distance, route, or duration of operation; Level 3 faults are those requiring the driver to stop immediately to address the issue or request assistance. The specific fault types corresponding to each level shall be defined by the enterprise service and management platform.

6.2.2 Fault notifications shall be issued in accordance with dynamic early warning and handling measures; fault handling information shall be recorded and reported in real time; and the format and definition of the reported data shall comply with the requirements of Table B.4.

6.3 Potential Hazard Alerts

Potential hazard alerts shall be issued in accordance with dynamic early warning and handling measures; potential hazard handling information shall be recorded and reported in real time;

and the format and definition of the reported data shall comply with the requirements of Table B.4. ......
