14、est Required Information. Refer to GMW14555 and Appendix B of this document “Required Data”. 3.6 Personnel/Skills. Refer to GMW14555 for basic requirements. All personnel shall be trained in high voltage safety and alternative propulsion vehicle safety protocol. This includes the alternative propuls
15、ion Electric Safety General Awareness course and Electric Safety procedure for the particular vehicle. These courses can be found by searching General Motors University (GMU) for Hybrids or contacting a Subject Matter Team (SMT) manager of alternative propulsion systems. 4 Procedure 4.1 Preparation.
16、 Refer to GMW14555 for basic requirements. Set up the vehicle with the normal GMW14555 and GMW15845 measuring locations and then add the additional measuring locations listed in Appendix A. 4.1.1 Vehicle Pre-Conditioning. 4.1.1.1 Battery Temperature Setting. Unless specified otherwise by the test pr
17、ocedure or by the specific requirements recorded in the VTS, the vehicle shall be conditioned to ensure that the ESS/RESS battery cell skin temperatures, as read by the on board controller, shall be within 3 C of the ambient temperature prior to the start of the vehicle tunnel test (not each test co
18、ndition). The ESS/RESS can be conditioned by blowing air across the battery pack or circulating coolant using the passive cooling loop. 4.1.1.2 Vehicle Temperature Conditioning. Unless specified otherwise by the test procedure or by the specific requirements recorded in the VTS, the vehicle shall be
19、 conditioned to ensure that the temperatures of the Engine Oil (if equipped), Transmission Oil (if equipped), and Seat Rail/Vehicle Structure shall be within 3 C of the ambient temperature prior to the start of the vehicle tunnel test (not each test condition). 4.2 Conditions. Refer to GMW14555 exce
20、pt as follows: 4.2.1 Environmental Conditions. The operating conditions of alternative propulsion vehicles require test in multiple ambient temperatures. Unless specified otherwise by the specific requirements recorded in the VTS, the default values for the required environmental conditions (ambient
21、, solar, and humidity) are defined in the test conditions. To enable on-road testing, a modification to the environmental conditions can be accepted if in the judgment of the responsible engineer it would not affect the test results. Due to vehicle calibrations and hybrid mode transitions, the addit
22、ional environmental conditions for worst case testing may be required. Development testing and knowledge of the system calibrations shall be used to determine any additional environmental conditions. 4.2.2 Test Conditions. Deviations from the requirements of this standard shall have been agreed upon
23、. Such requirements shall be specified on component drawings, test certificates, reports, etc. 4.2.2.1 ESS/RESS State of Charge (SOC) Setting. The hybrid ESS/RESS Battery State of Charge (SOC) shall be set to the starting State of Charge (SOC) as defined by the test before any Heating, Ventilation o
24、therwise multiple conditions shall be run for validation. In general “Min (minimum) SOC” is used for non-plug-in hybrids and Full SOC is used for plug-in vehicles. For some schedules plug-in vehicles with backup power (PHEV/EREV) will start from the Min SOC (the SOC that determines the onset of char
25、ge sustaining mode). 4.2.2.2 Rear HVAC Module Operation. For vehicles equipped with rear/auxiliary HVAC modules (including heater only, AC only and blower only systems) additional test conditions are required based on multiple rear HVAC settings. Tests shall be run with the rear/auxiliary systems in
26、 “mimic” mode to the front and also operated in “off” position. 4.3 Instructions. A vehicle program may not need to run all of the conditions of this procedure. The required conditions are dictated by the program VTS for the region and vehicle content. Check the condition paragraph to see which ones
27、 are optional based on the region and content. A reference summary of the conditions required versus content can be found in Appendix N. 4.3.1 Condition 1 Sequence Test Shutter Closed Ice Mode Min SOC (with Shutters Only).

The individual parts for these vehicles shall be run starting from Full SOC and then ending at Min SOC (for example the Rural Highway portion should be run back to back until the cha
