First PLUG-IN HYBRID with a star: S 500 PLUG-IN HYBRID - Efficiency = Performance

 

The new Mercedes-Benz S 500 PLUG-IN HYBRID blends an ultramodern hybrid drive configuration with the unique innovations and the luxurious equipment and appointments of the S-Class. The luxury saloon with a long wheelbase impresses with exceptional dynamism and efficiency. Thanks to standard pre-entry climate control it also offers unique climate comfort. The first certified three-litre luxury saloon in the world is a further milestone on the road to emission-free mobility. The first S 500 PLUG-IN HYBRID cars go to the customers this month.

"The S 500 PLUG-IN HYBRID is the first luxury saloon with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and a high-tech hybrid drive," says Prof. Dr. Thomas Weber, member of the Daimler Board of Management responsible for Group Research and Mercedes-Benz Cars Development.

"The new S 500 PLUG-IN HYBRID offers our customers the entire range of innovations that make our new S-Class so successful, and thanks to its intelligent operating strategy ensures outstanding driving pleasure and dynamism combined with the highest efficiency. Moreover, it allows completely emission-free driving for up to 33 km," adds Ola Källenius, Executive Vice President Sales and Marketing Mercedes-Benz Cars.

The Mercedes-Benz S 500 PLUG-IN HYBRID offers a system output of 325 kW and 650 Nm torque, sprints from 0 to 100 km/h in just 5.2 seconds and can drive up to 33 km purely electrically. The certified consumption is 2.8 litres/100 km, which corresponds to 65 g CO2/km emissions. Key elements of this impressive output are the V6 biturbo and the intelligent hybrid drive.

Following the S 400 HYBRID and S 300 BlueTEC HYBRID, the S 500 PLUG-IN HYBRID is the third hybrid model in the new S-Class. Its new high-voltage lithium-ion battery with an energy content of 8.7 kWh can be externally recharged via the charging socket in the right side of the rear bumper.

All three hybrid S-Class models have environmental certificates. These document the models’ environmental performance from development through to recycling, across the entire lifecycle, and the performance is certified to internationally recognised standards by independent experts. Regarding CO2 emissions the certificate of the S 500 PLUG-IN HYBRID states: "Over the entire lifecycle, comprising manufacture, use over 300,000 kilometres and recycling, clear advantages result compared with the S 500. External charging with the European electricity mix can cut CO2 emissions by some 43 percent (35 tonnes). Through the use of renewably generated hydroelectricity a 56 percent reduction (46 tonnes) is possible."

The hybrid transmission is based on the 7G-TRONIC PLUS 7-speed automatic transmission. The plug-in-hybrid system in the S-Class is based on the Mercedes-Benz parallel hybrid modular system. The common system-specific feature is the additional clutch integrated between combustion engine and electric motor. On the one hand, it decouples the combustion engine during purely electric operation; on the other hand, if the combustion engine is employed it affords the possibility to move off drawing on the performance of a wet start-up clutch. The clutch then substitutes for the torque converter and requires no additional space owing to its complete integration in the torque converter housing.

In order to strengthen the customers' trust in the new, innovative plug-in drive technology, for the S 500 PLUG-IN HYBRID Mercedes-Benz is for the first time issuing a certificate and thus a promise to perform for the high-voltage battery and plug-in components (e.g. electric motor and power electronics). This ensures that every technical malfunction within a period of six years after initial delivery or registration, or up to a mileage of 100,000 kilometres, is corrected by Mercedes-Benz.




Haptic accelerator pedal: support for the driver
Climb in, start, drive off and, as well as exemplary efficiency, on request experience via kickdown the special acceleration of the electric motor – this is how easy hybrid driving with the new S 500 PLUG-IN HYBRID is. For in everyday use it moves just as easily as any other automatic transmission car.

In the background, depending on the chosen operating mode the intelligent operating strategy automatically selects the ideal combination of internal combustion engine and electric motor and in so doing not only adapts its strategy according to the charge status of the battery; it also foresightedly adjusts it according to the traffic or route. But anyone wanting to can also intervene manually and with the aid of four operating modes and three transmission modes regulate the hybrid interplay themselves.

What is known as the haptic accelerator pedal can signal via a double impulse when drivers should take their foot off the accelerator for sailing and recuperating. During electric operation it can supply the driver with feedback on the switch-on point of the combustion engine. The energy flow is shown in all operating states in the instrument cluster and in the central display, if this is selected by the customer.

Extensive standard equipment, extended pre-entry climate control
The standard equipment in the S 500 PLUG-IN HYBRID is extensive and offers a world premiere: the extended pre-entry climate control. This is target value controlled. meaning that at the start of the journey the S-Class is air conditioned to the preset temperature if the driver has entered the departure time, via Mercedes connect me, for example. This is possible due to the electrically driven refrigerant compressor and electric heating elements for the heated air. In addition to this, when preheating it is not just the interior air but also the seats, steering wheel and armrests in the doors and centre console which are heated, and when cooling the seat ventilation is also activated if the respective optional extra is on board.

Also standard in the S 500 PLUG-IN HYBRID, which is only available with a long wheelbase, are for example LED High Performance headlamps and LED tail lights, leather upholstery, COMAND Online, touchpad, THERMOTRONIC automatic climate control plus seat heating also in the rear, Memory package for driver and front passenger, ambient lighting in seven colours and the air suspension AIRMATIC with continuously variable damping system. The basic safety equipment includes PRE-SAFE®, COLLISION PREVENTION ASSIST PLUS (collision warning including Adaptive Brake Assist), ATTENTION ASSIST, PRE-SAFE® impulse, Crosswind Assist and Traffic Sign Assist (traffic sign recognition incl. wrong-way warning function and display of speed limits in the instrument cluster). Over and above this a multitude of unique optional extras is available.

The Mercedes-Benz hybrid strategy: emphasis on plug-in drives
Following the S 400 HYBRID and S 300 BlueTEC HYBRID, the S 500 PLUG-IN HYBRID is the third hybrid model in the new S-Class. The series production launch of this technology began at Mercedes-Benz in 2009. The company is up there among the leaders in the field of purely electric mobility, too. In the years to come the main emphasis will be on plug-in hybrids.

Hybrid drives, the combination of internal combustion engine and electric drive, help cut overall fuel consumption and boost performance, since the electric drive replaces or supports the combustion engine whenever the engine characteristics are unfavourable — normally in part-load operation when little power is required.

The largest potential for lowering the energy consumption of hybrid drive systems lies in maximising energy recovery during coasting and braking. Upon depressing the brake pedal the deceleration is initially effected by the electric motor and not by the disc brakes. The hybrid models of the new S-Class are the first to use a recuperative braking system of the second generation. It ensures an unnoticeable overlapping of the conventional mechanical brakes and the electric braking performance of the electric motor in generator mode.

Intelligent operating strategy
For efficient operation, foresighted driving, avoiding unnecessary braking and accelerating manoeuvres, has always been the best strategy. This gains an all new importance in a hybrid model: braking manoeuvres serve not only deceleration, but can also be used to recuperate energy. And the route has considerable influence on the most efficient charging and discharge of the high-voltage battery.

The intelligent operating strategy supports the driver comprehensively yet unobtrusively to achieve the most efficient driving style. The control strategy, for example, seeks to ensure that the battery, if at all possible, is flat at the end of an uphill stretch so that it can be recharged going downhill. Another key point is the requirement that urban areas be reached with a fully charged battery, if possible, so that the vehicle can be operated in stop-and-go traffic electrically – frequently and efficiently.

In the S 500 PLUG-IN HYBRID the energy management system basically covers these three areas:
  • route-based: automatically or by way of four operating modes
  • driver-based: by way of three transmission modes
  • traffic-based: with the aid of radar.
Charging: power from a socket
The battery of the S 500 PLUG-IN HYBRID is safely fitted into the rear end of the S-Class to save space. An intelligent on-board charging system enables the battery to be charged at any conventional household power socket. The supply of electricity to the car will be made even easier in future through inductive, cableless charging.

The S 500 PLUG-IN HYBRID stores electric energy in a lithium-ion battery on lithium-iron phosphate basis. The water-cooled energy storage unit has an overall capacity of 8.7 kWh, a total weight of 114 kg and a spatial volume of 96 litres.

To ensure highest levels of crash safety and dynamic handling and also maximum boot space, the housing is made of die-cast aluminium and the high-voltage battery is located in the rear of the vehicle above the rear axle. The space available there is put to optimal use, and the S 500 PLUG-IN HYBRID thus takes first place among the plug-in hybrids in terms of boot capacity (395 litres) and luggage compartment accessibility.
The high-voltage battery of the S 500 PLUG-IN HYBRID can be charged via external electricity mains using a 3.6 kW on-board charger. The unit is permanently installed in the vehicle and charges single-phase up to 16 A. The connection for the charging cable is located under a flap in the rear bumper underneath the tail light on the right-hand side. An automatic lock ensures that the cable cannot be separated from the vehicle by unauthorised persons. The new S-Class can be charged in two hours anywhere in the world, e.g. at a wallbox or a charging pole (400 V, 16 A). Alternatively, charging via house connection is also possible, of course. Depending on the connection a charge time e.g. of two hours and 45 minutes can be attained (with 230 V and 13 A)[1].

Next step: S 500 PLUG-IN HYBRID – unplugged
One of the next steps on the way to the perfect electric vehicle and plug-in hybrid is cableless charging. Inductive battery charging will make the handling of electric vehicles and plug-in hybrids even more convenient. Mercedes-Benz will test this "unplugged" technology with the S 500 PLUG-IN HYBRID in order to develop a genuine S-Class solution, in terms of comfort and ease of operation, for the charging of the high-voltage battery.

The history: leadership role in the premium segment
In 1982 Mercedes-Benz presented the first concept vehicle with hybrid drive – a two-cylinder horizontally opposed engine served to charge the battery. A number of other experimental vehicles followed until in 2009 the world's first standard-specification hybrid drive with lithium-ion battery debuted at Mercedes-Benz: this S 400 HYBRID was the most fuel-efficient petrol-powered luxury saloon for a long time. And the most successful hybrid in its segment: with around 20,000 buyers.

Based on the 7G-TRONIC PLUS automatic transmission the second-generation hybrid transmission evolved. It premiered in 2012 in the E 300 BlueTEC HYBRID, the first diesel hybrid in the premium segment worldwide. By combining the efficiency of a diesel engine with the advantages of the hybrid drive, Mercedes-Benz set another milestone in the development of the automobile and advanced into consumption regions of 4 litres of diesel per 100 km in the luxury saloon segment.

With the C 300 BlueTEC HYBRID Mercedes-Benz has completed its hybrid portfolio below the luxury class. Moreover, in 2014 the B-Class Electric Drive, already on the market in the USA, will also become available in Europe to supplement the hybrid range.

Drive system: Efficiency = Performance

The Mercedes-Benz S 500 PLUG-IN HYBRID offers a system output of 325 kW and 650 Nm torque, sprints from 0 to 100 km/h in just 5.2 seconds and can drive up to 33 km purely electrically. The certified consumption is 2.8 litres/100 km, which corresponds to 65 g CO2/km emissions. The real-life consumption is also outstanding. Key elements of this impressive output are the V6 biturbo and the intelligent hybrid drive.

"The S 500 PLUG-IN HYBRID is the first luxury saloon with the performance of a V8 and the fuel consumption of a compact model. The greatest challenge in this is to translate efficiency into superior performance. In this respect there is a highly interesting parallel with our successful Formula 1 racing car, which likewise has a turbocharged V6 engine and a high-tech hybrid drive," says Prof. Dr. Thomas Weber, member of the Daimler Board of Management responsible for Group Research and Mercedes-Benz Cars Development.

Hybrid drives, the combination of internal combustion engine and electric drive, help cut overall fuel consumption and boost performance, since the electric drive replaces or supports the combustion engine whenever the engine characteristics are unfavourable – normally in part-load operation when little power is required. The experience gained with the previous vehicles from Mercedes-Benz has shown that though batteries with a higher energy content permit more frequent electric driving, they provide no added benefit from a consumption viewpoint. The capacity for braking energy recuperation determines the optimal design of the capacity and energy content of the traction battery. Recharging by the internal combustion engine cannot compensate for the additional vehicle weight resulting from an oversized battery.

For this reason, in the S 500 PLUG-IN HYBRID Mercedes-Benz combines a high-energy battery with the ability to replenish the energy storage unit via the external electric mains. The advantages of emission-free electric driving thus are brought ideally into line with the tremendous consumption advantage of the parallel hybrid – and combined with a ride comfort and handling dynamics which meet the highest standards. And a range that imposes no restrictions whatsoever on the driver.

As with all hybrid vehicles from Mercedes-Benz, the ultraefficient drive system is integrated in the overall vehicle in a way that creates no space restrictions. Major adjustments to the packaging of the overall vehicle are unnecessary – this is a big advantage for the production of the hybrid vehicles, for example, but it also poses a huge challenge for the development of the electric motor and its integration in the power head of the transmission and for the development of the power electronics and the high-voltage battery.

The hybrid transmission is based on the 7G-TRONIC PLUS 7-speed automatic transmission. The plug-in hybrid system in the S-Class is based on the Mercedes-Benz parallel hybrid modular system. The common system-specific feature is the additional clutch integrated between combustion engine and electric motor. On the one hand, it decouples the combustion engine during purely electric operation; on the other hand, if the combustion engine is employed it affords the possibility to move off drawing on the performance of a wet start-up clutch. The clutch then substitutes for the torque converter and requires no additional space owing to its complete integration in the torque converter housing.

For the stop phases of the combustion engine the hybrid system has a high-voltage refrigerant compressor, and on the 12 V side an electrically assisted steering, an electric vacuum pump and an electric auxiliary oil pump for the transmission.

Completely integrated: the electric motor
The electric motor of the PLUG-IN HYBRID has been further developed from the previous hybrid vehicles. The modular design enabled longitudinal scaling from 6 to 9 rotor plate packs. Despite its compact design the electric motor delivers an output of up to 85 kW and torque of up to 340 Nm. The permanently excited synchronous motor is fully integrated into the hybrid transmission. Stator and rotor of the internal rotor motor are cooled by transmission oil.

Power electronics and voltage transformer
The high-voltage battery feeds the electric motor through a water-cooled DC/AC converter, the power electronics. This too is a component from the Mercedes-Benz modular system and was first developed for the technology platform SLS AMG E-CELL, which went into production as the SLS AMG Coupé Electric Drive. The integration of the power electronics with an electric motor optimised for plug-in operation enables top performance in terms of comfort and output over the entire operating range.

The power electronics operate with a rated voltage of 325 V and supply 350 A maximum current, at the same time determining the position and status of the electric motor by means of a rotor position sensor as well as various component temperatures. Depending on operating situation, actuation of the electric motor is guided by the rotational speed or the torque, within the permissible limits. To optimise the effort for wiring, packaging and cooling, the DC/AC converter has been integrated into the engine space. A separate DC/DC converter at the rear of the vehicle supports the 12 V on-board power supply with an output of up to 3 kW.

With twin turbochargers: the internal combustion engine
For inherent design reasons, electric motors and combustion engines have different torque curves, which can, however, outstandingly complement each other. An electric motor makes its peak torque available as soon as it starts and can therefore compensate an internal combustion engine's weak torque in the low rev range. The electric motor and the V6 biturbo are thus ideal partners in the drive system of the S 500 PLUG-IN HYBRID.

The V6 biturbo with a displacement of three litres comes from the M276 engine family and features the BlueDIRECT injection and combustion system. Cylinder heads and block are made of aluminium. To reduce friction, the cylinder barrels are coated with the aid of the innovative NANOSLIDE process. Other engine characteristics include four valves per cylinder, a particularly quiet chain drive system with silent chains and two camshaft adjusters each for the intake and exhaust sides.

The third-generation direct injection system has a fuel pressure of 200 bar and spray-guided multiple injection with piezo injection nozzles. The on-demand vane-type oil pump cools and lubricates the engine depending on engine load and engine speed. The volume control distinguishes between a low and a high pressure level and adjusts the volume flow as required. The weight of the components of the water circuit could be reduced through the systematic use of plastic. In an extended temperature range the heating supply for the interior is preferentially served. The desired temperature is thus very quickly reached during the warm-up phase. An electric heater element ensures rapid warming of the car interior also during electric driving.

Depending on the power requirement and battery charge status, the S 500 PLUG-IN HYBRID drives in purely electric mode. Moving off from stationary also takes place in electric mode. This "silent start" is part of the exceptional driving experience and perfects the start/stop procedure, e.g. with noiseless starting at traffic lights. In transmission mode "S" electric driving can be excluded.

If more power is required, the internal combustion engine is started by means of a process developed specifically for hybrid drives with direct-injection petrol engines, and then is quickly and conveniently engaged by actuating the clutch, depending on operating conditions. The Mercedes-Benz starting procedure combines appropriate actuation of the starter with the ECO start/stop function of direct-injection petrol engines, in which starting is optimised by well-targeted injections and ignitions. This and the simultaneous actuation of the clutch, with its additional accelerating effect on the starting engine, make an extremely rapid start possible compared with a conventional starting procedure, ensuring a good transition from electric driving.

The internal combustion engine is shut off as often as possible for purely electric driving. But even so, in combination with the electric motor it delivers a total torque on the level of an eight-cylinder drive when such power is required.

Recuperative braking system: the electric motor as generator
The largest potential for lowering the energy consumption of hybrid drive systems lies in maximising energy recovery during coasting and braking. Upon depressing the brake pedal the deceleration is initially effected by the electric motor and not by the disc brakes. The hybrid models of the new S-Class are the first to use a recuperative braking system of the second generation. It ensures an unnoticeable overlapping of the conventional mechanical brakes and the electric braking performance of the electric motor in generator mode.

The driver's desired braking power is recorded by a pedal-travel sensor. The deceleration is dependent on the driving condition and is split into a recuperative brake-force portion and a portion to be supplied by the wheel brakes. The brake pressure on the rear axle is controlled dependent on the current recuperation potential of the drive system.

In addition, the combustion engine is switched off any time the vehicle is coasting, and its drag torque when rolling is used by the electric motor as recuperation torque. However, without depressing the brake pedal no additional deceleration torque is provided for charging the battery, and the vehicle can "sail."
