6 Future Car Clean Cities Alternative Fuel Data Center
Today I will be highlighting tools and resources on the Clean Cities, Alternative Fuels and Advanced Vehicles Data Center (hereafter the AFDC), and the Web sites. The Clean Cities and AFDC Web sites are supported by the National Renewable Energy Laboratory. The Web site is a partnership between the U.S. EPA and Department of Energy and is supported by Oak Ridge National Laboratory. After we explore these sites more thoroughly, I will provide you with the Web site address at the end of the presentation. Clean Cities Alternative Fuel Data Center

7 Maintenance Types OEM factory - dealer Third party – repair shop - ASE

8 Maintenance Hybrid EVs with ICE are similar maintenance to conventional vehicles All-electric vehicle typically require less maintenance than conventional vehicles Braking systems typically last longer due to regenerative braking Electric System does not require scheduled maintenance Batteries have limited number of charging cycles based on chemistry as defined by OEM

9 EV Standards and Codes for OEM
Safety Programs EV Standards and Codes for OEM Must Meet Federal Motor Safety Standards by NHTSA Current FMVSS Title 49 standard 305 – Safe Car Designs – Safety Citation – Emergency – NFPA EV safety –

10 EV Standards and Codes for OEM
Safety Practices EV Standards and Codes for OEM Undergo the same testing as conventional vehicles Battery packs –encased, sealed, impact, stress Test – overcharge, vibration, temperature, fire, collision Wired for insulated high-voltage lines and color coded Damage – safety deactivate electric systems Limit electrolyte spillage from batteries during crash Charging disconnects motor starter when plugged-in Charging cable brake-away/disconnects from charger driving

11 Safety Design Factors: High-Voltage Systems
Color Coding for Electric Drive Vehicles (NAFTC) Classification Low Voltage Intermediate Voltage High Voltage Voltage Ranges DC ≤ 30V ________ AC ≤ 15V DC > 30 ≤ 60v __________ AC > 15 ≤ 30v DC > 60v _________ AC > 30v >>360 Has two separate electrical systems A low-voltage system (12-volt DC) powers the accessories and the SLI. A high-voltage system (>60 volts) powers the motor generator (MG). The high-voltage system can be up to several hundred volts so never cut them. Lets expand a little here and explain some of the color coding and voltage levels that you will encounter in the field. Low Voltage = Cables could be Black or Red, Direct Current Voltages less than or equal to 30 volts, Alternating Current (AC) all voltages up to 15 vac. Intermediate Voltage = Identified by Blue Cables, DC Voltages between 30 and 60 volts (some GM vehicles), AC voltages between 15 and 30 volts High Voltage = Bright Orange cables, DC voltages from 60 volts and up (could be as high as 1000 volts), AC voltages greater than 30 volts. As mentioned, all of the auxiliary HV components (i.e. Power steering, air conditioning, cooling fans and pumps, etc.) operate on High Voltage AC (alternating current - 3 phase, which this means you will see 3 large bright Orange cables). The High Voltage DC (Direct Current from the High Voltage Battery, two large bright orange cables) is being changed within the inverter to supply the component with power. 11

12 Identification: Under the Hood
Under the hood, the voltage inverter will have decals or markings as indicated. There may also be a marking or decal on the engine cover. Wires will be color coded Briefly talk about the arrows NAFTC 12

13 Safety Design Factors:
High-Voltage Interlock Circuits Thermal Sensors High-Voltage GFCI circuit Inertia Switch High-Voltage fuse High-Voltage Service Disconnect High-Voltage Warning Labels There are several safety systems designed into the HEVs. Here is a list of those systems, both passive and active. Coloring of high-voltage cables High Voltage Warning Labels Thermal Sensors in HV Battery Pack Impact inertia switch High Voltage inter-lock system Ground Fault Circuit Interrupts (GFCI) High Voltage Safety disconnect High Voltage Fuse The full training program provides an in-depth discussion of all these safety design factors.

14 General Reminders Even when the ICE is off, high voltage may be present. The ICE may start at any time unless disabled. (smartkey) HEVs can be treated much like any other vehicle in an accident. Disconnecting the 12 volt battery disables high-voltage controller As mention previously in this presentation, even though the IC engine may not be currently running there is a potential for this happen very quickly under certain conditions (key on, throttle input, call for heating or cooling, etc.) If this where to happen the vehicle could move on it own, this would not be a good situation. Hybrid Electric Vehicles have some different operational modes and high voltage components that makes them unique. Generally these vehicles can be treated much like our conventional vehicles. REPEAT THIS STATEMENT: Do not assume that the vehicle is immobile just because there is no key in the ignition. Some vehicles might have a proximity key system. Note: Do not assume that the vehicle is immobile just because there is no key in the ignition. NAFTC 14

15 Crash and Fire Procedures
Vehicle fires can be handled like any conventional vehicle except in the case of a battery fire. In the event of a battery fire of the high-voltage battery system, use large volumes of water to help to cool battery cells around the burning cells. Do not attempt to open the battery pack. Use extreme caution when working in wet or damp areas Do not cut any orange (high-voltage) cables. In the event you roll up on a scene and the vehicle is a Hybrid Electric Vehicle and it is fully involved, many of the same techniques that you currently use to fight a vehicle fire will be used for hybrid electric vehicle. However some special considerations will need to be used to address the high voltage battery. One of those considerations is the use of large volumes of water to cool the battery cells. Many high voltage battery packs are constructed of either aluminum or plastic. Follow the recommended procedure outlined in your Quick Reference Guides. A safe work environment is critical to all those involved. Never open or pry open and high voltage battery pack and most certainly NEVER cut a bright orange cable. 15

16 Vehicle Occupant Safety
Primary risks are the same as a conventional vehicle. The risk of exposure to toxic battery materials is low. Even in the event of catastrophic battery damage, the release of the electrolyte will be small. In the event of exposure, flush with water. Potential airbag deployment must be considered. system 16
