Overview of task force issues and objectives concerning malfunction diagnostics and driver/occupant hazard warnings specific to battery electric vehicles.

The purpose of the testing is to stress a rechargeable energy storage system (REESS) from both an electrical and mechanical standpoint to verify that there are no safety issues that arise from mechanical shock, vibration and temperature excursions in real world applications.

At the 8th EVS GTR IWG meeting in Changchun, members of EVS Task Force 1 continued to discuss proposed requirements and test procedures (EVS-08-17) to address the safety performance of EVs during in-use in events of flooding and vehicle washing. As an action item, members were requested to provide comments on the overall proposal, specifically, water depth (10cm) and vehicle speed (20 km/h) for the drive test. The US believes that a 10 cm water depth test presents a reasonable and likely scenario for testing electric vehicle performance.

NHTSA recommendations for the state-of-charge of the energy system of plug-in and fuel-cell vehicles at the time of testing and on the conditioning procedures prior to testing.

US proposal for sequential fault testing of battery management systems.

NHTSA note proposing that the specific battery SOC measurement procedure be determined by manufacturer in accordance with the battery design.

Proposed text for a sequential testing program to test the Battery Management System (BMS) response at the safety boundary limits of the REESS during operation. The test evaluates the ability of the vehicle’s BMS to safely monitor and control the REESS under external inputs such that there is no damage to the REESS and no hazardous conditions arise.

Revised U.S. proposal for BMS functionality and sequential fault testing requirements

US proposal taking into account and responding to comments received from JRC (22 April 2016) and OICA (17 May 2016)

Presentation by NHTSA’s Nha Nguyen on agency strategies for enhancing motorcoach safety: Seat Belts, Stability Control Systems, Rollover Structural Integrity, Emergency Evacuation, Fire Safety, Glazing and Window Retention, Event Data Recorders (EDRs), Tires and Crash Avoidance Systems.

Presentation on NHTSA’s proposal to enhance the FMVSS 210 test procedure for seat-belt anchorages through the use of an improved pair of “force-application devices” (FAD).

US comments on child restraint systems based upon NHTSA’s National Child Restraint Use Special Study (NCRUSS), including recommendations on their installation, use, and testing thresholds.

NHTSA presentation on the agency’s experience and investigations concerning low-speed vehicles and three-wheeled motorcycles. This presentation broadly considers very light vehicles mainly intended for local (neighborhood), short-distance transportation.
