EVS-GTR Task Force 9
Scope:
Task force 9 will address the communication between the rechargeable energy storage system REESS
and the vehicle operator (driver). The TF will identify the safety issues with the REESS including the
battery management system (BMS), charging, thermal event and charge level indicator which require
driver information and develop appropriate provisions for a warning system.
Operating Principles:
•
TF will prepare an action plan to address the safety issues and an approach to establish a
solution for warnings to the driver. The plan will be submitted to the leadership of the EVS-IWG.
•
The TF will address the issues based on the principles in the TOR of the EVS-IWG.
•
The TF leaders will arrange face to face meetings, teleconferences and web conferences or email
exchanges as appropriate.
•
The solution (requirements, test procedures and justifications) will be science-based with
supporting data and analysis.
•
The TF will elaborate and document different options, evaluate analysis and data; and prepare
common positions and/or recommendations.

Identify safety-critical information needs and effective methods to communicate this
information to operators.

; Determine warning and messaging needs for operators and when to warn.

Task Force 9 will work with other task forces to identify parameters for warning systems.


Develop requirements and test procedures

To the extent possible, the TF will seek to harmonize possible universal warning symbols

Draft report that discusses task force decisions. The TF will provide a progress report and final
report to EVS-IWG.

The TF will raise any unresolved issues and propose recommendations to the co-sponsorship of
the IWG.
