Description Cayenne/Panamera S Hybrid & Cayenne/Panamera S E-Hybrid A 3.0 l V6 supercharged engine with direct fuel injection installed in the Cayenne/Panamera Hybrids guarantees maximum efficiency of the hybrid drive in conjunction with an electric machine In addition to ensuring typical Porsche driving characteristics with V8 performance, the main development goal was to achieve low fuel consumption, reduced CO2 emissions and compliance with all worldwide emission standards Porsche is using a supercharged V6 engine for the first time The engine produces 333 hp (245 kW) at 5,500 rpm to 6,500 rpm and delivers a maximum torque of 440 Nm in the range between 3,000 rpm and 5,250 rpm Characteristics The most important characteristics of the new 3.0 l V6 supercharged engine include: The Cayenne S Hybrid, Panamera S Hybrid, Cayenne S EHybrid and Panamera S E-Hybrid share the 3.0 liter Supercharged V6 first introduced with the 2011 Cayenne S Hybrid Hybrid 3.0 TFSI Engine Data No of

Four-valve technology Charge-air cooling Continuous camshaft adjustment Fuel consumption measures on intake side The engine is a 6-cylinder, 24-valve gasoline engine with a cylinder bank angle of 90 degrees and two camshafts per cylinder bank The 3.0 l V6 engine consists of an aluminum engine block, an aluminum cylinder head and other state-of-the-art technological features such as thermal management and a regulated oil pump The oil supply system is based on the principle of wetsump lubrication, which safeguards the functions of the engine in dynamic driving mode and on slopes or steep uphill climbs when driving off-road, for example In contrast to previous turbocharged engines used in Porsche models, turbocharging on the new unit is achieved using a supercharger with charge-air cooling The supercharger with charge-air cooling offers special advantages for the specialized use and characteristics of the full parallel hybrid drive in an SUV/sedan Because the supercharger has a permanent mechanical connection with the crankshaft drive, the boost pressure is available immediately Hybrid Technology & High Voltage Safety Electrics & Electronics Phase 2: Repairs to the High-voltage Battery Return Points The second repair stage is expected to be introduced in 2015 The replacement of cell modules and other components is planned at present These repairs can already be carried out in special repair facilities provided by the supplier of the high-voltage battery The return point for US Porsche dealerships will be Atlanta, Georgia Faulty and critical high-voltage batteries are sent for recycling locally All local and regional regulations regarding handling and shipping must be observed when transporting high-voltage lithium-ion batteries Shipping of Lithium-ion Batteries High-voltage batteries that are faulty but have been assessed by the HVT/HVE as non-critical or critical can sometimes be repaired The repairs that can be carried out by the HVT are described in the section “Replacing damaged high-voltage components” The relevant procedures must be observed if the high-voltage lithium-ion batteries need to be packaged, stored, and transported The high-voltage lithium-ion battery in the Panamera S EHybrid is categorized as a class hazardous material As such, the batteries are subject to certain transport restrictions Shipping of Non-critical High-voltage Batteries Beginning in 2014, faulty, non-critical, high-voltage batteries that cannot be repaired by the HVT/HVE will be shipped to the North American repair facility for repair Shipping of Critical High-voltage Batteries Panamera S E-Hybrid Faulty, critical, high-voltage batteries that cannot be repaired by the HVT/HVE must be sent to a local disposal company, if applicable after a quarantine period They can be transported by road in special packaging after this quarantine period Critical batteries may only be transported by road Special packaging is required for this (see the following section “Packaging of critical high-voltage batteries”) Shipping of Dangerous High-voltage Batteries Dangerous high-voltage batteries are not shipped due to the increased risk of fire and explosion The fire department must be called as soon as a high-voltage battery is identified as being in dangerous condition The high-voltage batteries will be repaired and returned to the Porsche dealer within days from the day they are sent to the repair facility Sending a high-voltage battery to a repair facility makes sense if the repair can be combined with a module (8 cell) replacement The decision about whether the high-voltage battery needs to be sent to a repair facility is always made by Porsche Cars North America, Inc (PCNA) after consultation with the respective support group at Porsche AG Non-critical batteries can be shipped in the original spare parts packaging using all transport carriers Page 9b.24 Hybrid Technology & High Voltage Safety Electrics & Electronics Recycling of Old and Faulty High-voltage Lithium-ion Batteries The Porsche environmental concept is based on a clear waste hierarchy Porsche Environmental Concept Recycle high-voltage batteries that can no longer be repaired Faulty and critical, high-voltage batteries must be sent for recycling locally because of the strict transport restrictions that apply to them These batteries are disassembled by specialist recycling companies and the individual components are recycled Market-specific return and recycling solutions taking into consideration legal and logistical aspects are required because of the strict transport restrictions in place worldwide, particularly for critical batteries Possible transport and export restrictions for used and old batteries have a major impact on the choice of recycling options Reduce waste Disposal of a complete battery can be avoided with a repair strategy (e.g by replacing components) Reuse used and old batteries Non-critical used and old batteries are taken back free of charge by the supplier and conditioned for reuse Twenty-five Porsche return points have been established worldwide for taking back non-critical, old batteries Panamera S E-Hybrid Notes: Hybrid Technology & High Voltage Safety Page 9b.25 Electrics & Electronics Packaging of High-voltage Lithium-ion Batteries and Their Components Lithium-ion batteries are always a hazardous material that must be packaged properly before being shipped Different packaging types must be used for non-critical and critical high-voltage batteries Dangerous lithium-ion batteries must not be shipped Partial disassembly of the high-voltage battery in the Porsche dealership by the HVE can be necessary prior to shipping e.g if a high-voltage battery is so badly damaged after an accident that it no longer fits in the battery packaging provided There is separate packaging for shipping cell modules General packaging requirements for high-voltage lithiumion batteries and their components are: • Remove exterior dirt before packaging • Protect the electrical terminals • Ensure there are no compressive loads • If necessary, remove any coolant that has escaped an securely seal all openings • Make sure that no electrolyte or hydrofluoric acid can escape from the packaging Packaging of Non-critical High-voltage Batteries Panamera S E-Hybrid Non-critical high-voltage batteries are packaged in the same packaging they were originally delivered in This is a type-tested wooden box in which the high-voltage battery is securely fixed in place This is the only packaging that may be used because it meets the international transport regulations and has been safety checked In-house constructions or other transport systems are not permitted Insulation material (rock wool) Outer wooden crate Inner wooden crate Gas locks The packaging has the following characteristics: • Type tested with certificate from the German Federal Institute for Materials Research and Testing • Can be reused a number of times • Can be stacked at least three high • Protected against ESD (electrostatic discharge) • Silicate pouches for dehumidification • Mechanical securing of the battery Page 9b.26 Hybrid Technology & High Voltage Safety Electrics & Electronics Packaging of Critical High-voltage Batteries Critical high-voltage batteries must be packaged correctly in a special container by the HVT before transport The packaging concept developed by Porsche, and the German Technical Inspection Association (TÜV) is also called a “box in the box” concept It consists of an outer wooden crate and an inner wooden crate (packaging class 1, hazardous material class 9) Inside (between the wooden crates and inside the inner crate) is a high-temperature-resistant insulating material (rock wool) The packaging also contains two gas locks The packaging for critical high-voltage batteries (pack and modules) can be ordered from Porsche Important! Porsche provides suitable transport containers for shipping high-voltage batteries and high-voltage battery components The use of containers fabricated in-house is not permitted Important! Any liquid that escapes from the high-voltage battery must be collected using a suitable binding agent and disposed of correctly Panamera S E-Hybrid Example of packaging for critical high-voltage lithium-ion battery Notes: Hybrid Technology & High Voltage Safety Page 9b.27 Electrics & Electronics Interim Storage of High-voltage Batteries Critical High-voltage Batteries Standards for safe storage of lithium-ion batteries have been defined for the warehouse and workshop Depending on the condition of the lithium-ion battery, safe interim storage must be provided so that no damage can occur (e.g due to a battery falling) Stacking of high-voltage batteries is not permitted The type of high-voltage battery storage differs depending on the result of the risk assessment (classification) and the condition of the high-voltage battery If quarantine is required for a critical condition, the vehicles containing these batteries must be parked in a previously defined parking location away from buildings for five days before the batteries are sent to a recycling company The vehicle is identified using the cordon barrier available from Porsche and the associated warning signs (see the section “Visual warning notices”) If the battery is no longer in the vehicle, it is stored in a rainproof skeleton container during the quarantine period to prevent access by unauthorized parties Non-critical High-voltage Batteries High-voltage lithium-ion batteries classified as non-critical can, for the most part, be placed in interim storage in the parts warehouse They must be protected against mechanical damage (on the floor, not stacked, away from moving traffic) and water An ABC fire extinguisher must be positioned near the interim storage to prevent fire spreading from other objects to the lithium-ion batteries Porsche recommends using the original spare parts packaging for interim storage Panamera S E-Hybrid Page 9b.28 Hybrid Technology & High Voltage Safety Electrics & Electronics Subject Page General Information Safety Measures on the Cayenne S E-Hybrid Cayenne S E-Hybrid Infotainment Systems Hybrid Technology & High Voltage Safety Page 9c.1 Electrics & Electronics General information System overview of safety-related high-voltage components A variety of measures were successfully implemented during the development of the Porsche E-Hybrid vehicles, i.e the Panamera S E-Hybrid, 918 Spyder and Cayenne S E-Hybrid A very high level of safety has been achieved In addition to system knowledge and the available media in the PIWIS information system, the technicians worldwide have all the necessary knowledge in order to service and repair the vehicles This chapter on the topic of high-voltage safety is based on the following documents: • Cayenne S Hybrid Training Information • Panamera S E-Hybrid Training Information Safety measures on the Cayenne S E-Hybrid As already introduced for the Panamera S E-Hybrid, the current regulations for working on E-Hybrid vehicles apply Handling of the lithium-ion batteries in particular requires detailed specialized knowledge and may only be carried out by authorized and trained personnel in the Porsche dealership In addition to the country-specific safety regulations, the safety instructions in the PIWIS information system apply The components in the Cayenne S E-Hybrid largely correspond to those in the Panamera S E-Hybrid The installation positions of the high-voltage components are shown in figure 9_01_15 Due to the discontinuation of the highvoltage distributor with the lines for the electric A/C compressor and the passenger compartment high-voltage heater, the free and unassigned connection on the highvoltage charger adopted from the Panamera S E-Hybrid is connected directly to the high-voltage heater in the Cayenne S E-Hybrid In terms of the high-voltage charger, a distinction is made between the 3.6 kW and 7.2 kW high-voltage charger Depending on the charging power, a modified safety contact is used on the high-voltage charger for connection of the high-voltage cable from the charging tray Control of the high-voltage charger is via an additional Inumber The 7.2 kW charger option involves delivery of a universal 7.2 kW (AC) charger and the relevant accessories Cayenne S E-Hybrid High-voltage topology and installation position of high-voltage components in the Cayenne S E-Hybrid Hybrid module Electric A/C compressor Power electronics Page 9c.2 Passenger compartment highvoltage heater High-voltage charger 9_01_15 High-voltage battery high-voltage heater High-voltage battery Hybrid Technology & High Voltage Safety Electrics & Electronics The pilot line is a ring line whose two ends are connected to the battery manager at the Ebox It passes through all the high-voltage line connections with the exception of the electric machine When the connecting lines to the electric machine are disconnected, the pilot line is interrupted via the pilot line contacts in the cover of the power electronics when the cover is opened If the pilot line is interrupted, the battery manager registers this and allows the high-voltage contactors to open up to a speed of 1.8 mph (3 km/h); this electrically disconnects all the other high-voltage components from the high-voltage battery For safety reasons (e.g vehicle currently overtaking/passing), the high-voltage system is not switched off if the pilot line is interrupted above a speed of 1.8 mph (3 km/h) A red message appears on the instrument cluster (see figure 09_02_15) The driver can continue driving with the combustion engine If the driver responds to the message and stops the vehicle, the system is switched off at a speed below 1.8 mph (3 km/h) 9_02_15 Pilot line in the Cayenne

High-voltage charger Hybrid Technology & High Voltage Safety Page 9c.3 Cayenne S E-Hybrid Pilot line Electrics & Electronics 12 V service disconnector Charging methods The 12 V service disconnector in the Cayenne S E-Hybrid is located underneath the right-hand cover in the luggage compartment (see figure 9_04_15) As with all E-Hybrid vehicles, the 12 V service disconnector disconnects the pilot line and the voltage supply (from terminal 30) to the contactors The contactors are therefore switched to ground by the battery manager If the 12 V service disconnector is interrupted, the contactors are also de-energized if the battery manager does not respond to the signal from the pilot line (fault protection) Mode (AC) Charging from a standard electrical socket up to maximum 16 A, three-phase, without communication with the vehicle – the charger is installed in the vehicle This charging method is not implemented by Porsche Mode (AC) Charging from a standard electrical socket up to maximum 32 A, three-phase, with a control and protection function integrated in the cable or wall outlet – the charger is installed in the vehicle Implemented on the Panamera S E-Hybrid, Cayenne S E-Hybrid and 918 Spyder Mode (AC) Charging at charging stations using a special charging connection device up to 63 A, three-phase, for electric vehicles with permanently installed control and protection function – the charger is installed in the vehicle Implemented on the Panamera S E-Hybrid, Cayenne S EHybrid and 918 Spyder Mode (DC) Service disconnector 9_05_15 Safety of charging equipment Cayenne S E-Hybrid All the safety functions described in the Panamera S EHybrid Training Information are implemented in the Cayenne S E-Hybrid The special features of the charging methods and the operating principle of both high-voltage chargers are covered in detail here Page 9c.4 Charging at direct current charging stations using a special charging connection device for electric vehicles with a permanently installed control and protection function – the charger is installed in the charging station, the charging cable is permanently connected to the charging station Only implemented in the 918 Spyder Communication of charging infrastructure The charging infrastructure can be communicated with the aid of the two pilot line contacts CP (control pilot) and PP (proximity pilot) in accordance with the protocol for the type (USA) plug connection Here, the charging infrastructure communicates with the charger in the vehicle, i.e communication between the universal AC charger of the public charging pedestal and the highvoltage charger in the vehicle applies to all Porsche EHybrid vehicles The charging enable and charge status (CP) information, as well as the maximum possible charging currents (PP) can be communicated via the two pilot lines Hybrid Technology & High Voltage Safety Electrics & Electronics Measurement of the resistance values between the CP and PE (protective earth) provides the current status of the charging plug connection For this purpose, the charging infrastructure (universal AC charger or public charging pedestal) transmits a ±12 V, kHz square-wave signal to the CP connection The status and the requirement are returned from the vehicle with the aid of a diode and a resistor The universal AC charger or the public charging pedestal communicate the maximum power output via a pulse width modulated or square wave signal CP-PE circuit diagram 9_08_15 PP-PE circuit diagram 9_09_15 Infotainment systems For the first time, both the optional Bose® or the Burmester® sound system are available for the Cayenne S E-Hybrid For this purpose, the subwoofers have been specially adapted to the available space in the Cayenne S E-Hybrid Cayenne S E-Hybrid The two equivalent circuit diagrams (09_08_15 and 09_09_15) illustrate that the two pilot contacts form two separate circuits together with the PE connection Communication between the vehicle and the charging infrastructure is enabled via the two circuits, without the use of bus technology A fault in one of the two pilot line connections leads to rejection or termination of the charging process The recessed pilot line contact CP ensures that the charging cable has been fully plugged into the vehicle-side charging port before a query of the connection status takes place Communication within the high-voltage charger takes place via analog/digital converters The measured values at the measuring points are converted into digital signals and made available to the microcontroller Hybrid Technology & High Voltage Safety Page 9c.5 Electrics & Electronics Notes: Cayenne S E-Hybrid Page 9c.6 Hybrid Technology & High Voltage Safety Conversion Charts Temperature
