2 W W W Chevrolet VOLT First Responder Training 2 hr Training Session – Vehicle Introduction – Battery and Electrical Technology – Emergency Operations – Response to the Incident Compiled by: Captain Frank Doyle Lt. Paul Gross FF. Gregory Myers


4 GM Electric and Hybrid Programs Continue… GM-Allison Hybrid Bus Chevrolet Tahoe & GMC Yukon Cadillac Escalade Silverado & Sierra FWD Hybrid Plug-in HEV Saturn AURA Hybrid Saturn VUE Hybrid Chevrolet Malibu Hybrid Volt Shanghai-GM Buick Hybrid Lithium Ion for new programs launching in this timeframe RWD 2-Mode Hybrid Plug-In Hybrid Voltec EREV GM Hybrid GM-Allison Hybrid More than 10 years of hybrid-electric technology

5 Key Electrical Technology of the Volt

6 Safety Overview Structure and Safety Integration

7 Daytime Running Lights Electronic Stability Control System Anti-Lock Braking System Systems to Help Absorb Energy from Impact Automatic Crash Response Post-Crash Occupant Protection Automatic Door Unlock Automatic Flashers Automatic High Voltage Shutoff Fuel Sender Shutoff BEFOREAFTERDURING Chevrolet Volt Continuous Safety Protection Before, During, and After Vehicle Collisions Comprehensive Safety

12 100% Electrical Propulsion Volt Battery w/Cover Volt Battery w/o Cover Manual Service Disconnect Electrical Interface to Vehicle (Battery Disconnect Unit) Sealed Battery Pack, Electrically Isolated System

13 First Responder Field Scenarios Standard Operating Procedures : Size-Up, Approach, Immobilize, Extinguish Vehicle on Fire NO increased risk to first responders Vehicle in Water NO increased risk of shock hazard

14 Vehicle Labeling Strategy – Danger & Warning – Color Coding – High Voltage Disconnect

17 Emergency Operations Involving Advanced Electric Vehicles

18 How will HEVs and EVs affect my response?

19 Perceived Issues Concern: High voltage batteries will leak dangerous amounts of fluid if damaged. Reality: Batteries are not lead acid. NiMH and Li-Ion are dry cell batteries. Electrolyte is absorbed in a medium. A few drops may be produced if cell is crushed.

20 Perceived Issues Concern: I risk electrocution by touching an HEV/EV involved in a crash or is submerged. Reality: High voltage system is completely isolated from chassis. Integrated safety systems and basic electrical theory protect occupants and responders.

21 Perceived Issues Concern: It will be difficult to disable the HV electrical system. Reality: Integrated shutdowns in the event of a crash. Shutting off the vehicles ignition will shut down High voltage. Backed up by 12v battery disconnection.

22 Perceived Issues

23 Reality: Fires in HEVs and Evs are extinguished with standard firefighting procedures. Concern: Special Equipment is needed for vehicle fires.

24 Actual Issues Solution: Always ensure vehicle is shut down and secured from moving. Issue: Unexpected movement is a serious concern for responders.

25 Actual Issues Solution: Automatic safety shutdowns. Simple additional shutdown procedures. HV isolation from chassis. System fuses. Break in outer mesh of wire initiates shutdown. Issue: High voltage systems ranges from 100v to 360v DC and up to 650v AC.


27 Safety Procedures Identify Immobilize Disable

28 Safety Procedures –Identification There are many types of labeling systems!

29 Safety Procedures -Identification Identification is not always easy due to damage.

30 Safety Procedures - Immobilize Chock the Wheels Engage Emergency Brake Place Vehicle in Park

31 Safety Procedures HV Disconnect 1 Turn Vehicle OFF (push Start/Stop button- gauges turn off)

32 High Voltage Disconnect Procedure 2 Access 12V Cut Locations (left side of trunk)

33 Making the Volt safe for patient extrication: Cut the 12 volt cable in the trunk where it is labeled. – You will need to cut the cable in two spots. – Both cut marks are labeled on the cable

34 High Voltage Disconnect Procedure 3 Cut and Remove Section of 12V Cable

35 High Voltage Cables The high voltage cables are not in the typical cut areas. – Always peel interior paneling before you cut. The high voltage cables are orange but they may have black plastic around them for protection.

36 Other information The high volt battery has sensors that should disconnect the batteries power during impact. If concerned that the high volt battery was not disconnected during impact. – Pull the high voltage manual service disconnect – Simply pulling the high voltage manual service disconnect will not disconnect the 12 volt power. – Still cut the 12 volt cable in the trunk

37 12 Volt Disconnect If you can not access the 12 volt cable in the trunk. – Pull all fuses in the fuse box – This will disable the airbags – Fuse box is on the dash by the drivers door Also there is access to the 12 volt cable in between the B and C post in the rocker panel on the drivers side. – The cable is RED

38 Standard Responses

39 Making the Volt safe for patient extrication Approach the vehicle from the side Chock the wheels Make sure the vehicle is turned off. – If the LCD screens are illuminated the Volt is running – You can not hear the Volt when running on battery power – As a safety if you open the hood while the Volt is running on battery power the generator will start. – The generator sounds like an engine.

40 Crashes/Extrications Follow Recommend Shut Down Procedures. No Special Extrication Techniques. Be Aware of HV Components and Wiring.

41 Fire attack on the high voltage battery DC Power does not seek a path to ground. ABC extinguishers will not work Copious amounts of water will work The batteries are not lead acid so they will not leak dangerous amounts of fluid. Once the battery is involved, consider defensive attack if there are no exposures.

42 Submersion No additional hazards for hybrid vehicles. Some bubbling at battery terminals if water is contaminated.

43 CONCLUSION HV vehicles will continue to evolve. Education is key to safety!!
