27Automotive ServiceThis diagram shows the components included in a typical series-hybrid design. The solid-line arrow indicates the transmission of torque to the drive wheels. The dotted-line arrows indicate the transmission of electrical current.
28Automotive ServiceThe power flow in a typical parallel-hybrid vehicle.
29Automotive ServiceDiagram showing the components involved in a typical parallel-hybrid vehicle. The solid-line arrows indicate the transmission of torque to the drive wheels, and the dotted-line arrows indicate the flow of electrical current.
30BELT ALTERNATOR STARTER SYSTEMS (BAS) Automotive ServiceBELT ALTERNATOR STARTER SYSTEMS (BAS)The belt system, called the belt alternator starter (BAS), is the least expensive system that can still claim the vehicle is a hybrid. For many buyers, cost is a major concern and the BAS system allows certain hybrid features without an entire redesign of the engine and power train. Consumers can upgrade to BAS hybrids at a reasonable cost and will get a 2% to 5% increase in fuel economy, mostly affecting city mileage. BAS replaces the belt-driven alternator with an electric motor that serves as a generator and motor. When the engine is running the motor, acting as a generator will charge a separate 36-volt battery (42-volt charging voltage).When the engine needs to be started again after being in idle stop, the BAS motor cranks the engine by taking power from the 36-volt battery pack and applies its torque via the accessory belt
31Automotive ServiceThe BAS system is used in the Saturn VUE hybrid SUV.
32Automotive Service________ - ____ hybrids can be connected to volt home outletto fully recharge the battery pack.
41Automotive Service__________________ braking uses the kinetic energy of normal stopping torecharge the high voltage battery pack. NOTE: During quick, hard braking the conventional hydraulic system is used.RegurgitateRegenerativeMy Generation
43Automotive ServiceHybrids use 2 voltage systems, the high-voltage system for the drive systemand a ___ - volt system for the vehicle’s conventional electrical & electroniccomponents – including the computer systems.MediumUltra-HighLow
44Automotive Service The hybrid high-voltage system can range from ______ to ______ volts ac or dc…That’s deadly!250 to 650360 to 42090 to 100
46Automotive ServiceHigh-voltage power cables are large in diameter and easily identified by theirbright _________ color.YellowBlueOrange
47Automotive ServiceWARNING: Power remains in the high-voltage electrical system for up to 10 minutes after the HV battery pack is shut off. Never touch, cut, or open any orange high-voltage power cable or high-voltage component without confirming that the high voltage has been completely discharged.
48Automotive ServiceJump-Starting The 12-volt auxiliary battery may be jump-started if the vehicle does not start. The 12-volt auxiliary battery is often located under the hood but can also be located in the cargo area of some HEVs.
49Automotive ServiceThe full hybrid motor-generator or “MG” has 4 basic functions:Helps power the _________ _________ and propel the vehicle__________________ the high-voltage battery pack_____________ the internal combustion engineHelps to _________ and ________ the vehicle
60Automotive ServiceThe __________ _____________ is a planetary gearset used to controlthe transfer of power through the hybrid drive train. It is computer-controlled.
61Automotive ServiceThe __________ _____________ is a planetary gearset used to controlthe transfer of power through the hybrid drive train. It is computer-controlled.
62Automotive ServiceFor safety against short circuits and electrocution, __________ __________interrupters, impact sensors or ___________ switches and high voltage fusesare used in hybrid systems.Ground Fault & InertiaPower Fault & InertiaNobody’s Fault & Inertia
63Automotive ServiceHybrid systems can be cooled by ______________ coolant, by blower fancirculating ________ past the battery pack, and/or by a separate R-134arefrigerant cooling system.Engine & AirPassenger & AirRefrigerant & Air
65Automotive ServiceThe hybrid power display informs the driver with a ________ ______ light,a ____________ warning light, a ______________ ________ warning light,and a conventional MIL.Drive Ready, Master, Battery Pack
68Automotive ServiceBesides wearing safety glasses, removing all conductive jewelry, and creatinga high-voltage buffer zone when working on hybrids, OHSA-approvedgloves with a _________ volt insulation value must be worn.2507501000
70Automotive ServiceUse of a warning cover over the steering wheel helps others realize that work is being performed on the high-voltage system and that no one is to attempt to start or move the vehicle.A lock box is a safe location to keep the ignition keys of a hybrid electric vehicle while it is being serviced. Notice that this lock box has two separate locks so it would require two people to open, helping to insure that no harm is done by accidentally attempting to start a HEV.
71Automotive ServiceInsulated tools, such as this socket set, would provide an additional margin of safety to the service technician when working around high-voltage components and systems.
89Hy-WireHy-wire is a descendant of the GM Autonomy released at the 2002 North American International Auto show. The Autonomy is a car which combines a hydrogen fuel cell with drive by wire technology. These technologies in combination allow all the mechanicals of the car to reside as a separate component to the body and passenger space.A single docking port provides the electrical connection between the chassis and body. There are 10 pick-up points where the body mounts the chassis. Such few attachments provide maximum flexibility when designing a body.
