- 1. NAME: S.H.Sasikant REG no. 10BEM0053 Faculty: Sandip Sarkar Sir
- 4. Rolls-Royce Limited was a renowned British car and, from 1914 on, aero-engine manufacturing company founded by Charles Stewart Rolls and Henry Royce on 15 March 1906 as the result of a partnership formed in 1904. HISTORY
- 5. In 1884, Henry Royce started an electrical and mechanical business. He made his first car, a two-cylinder Royce 10, in his Manchester factory in 1904, and was introduced to Charles Rolls at the Midland Hotel in Manchester on 4 May of that year. Rolls was proprietor of an early motor car dealership, C.S.Rolls & Co. in Fulham.

- 17. BATTERY Phantom EE is thought to have the largest passenger car battery in the world. Peak current is 850A, delivered at 338V DC. Overall capacity is 71kWh. The pack is comprised of large-format NCM pouch cells. NCM (Lithium-Nickel-Cobalt-Manganese-Oxide) is a variant of lithium-ion chemistry that has particularly high energy and power densities.
- 18. Three separate charger units (3kW each) are fitted to the battery, which allow both single-phase (20 hours) or three-phase charging (8 hours); for a passenger car this is unique. A fourth induction charger is also fitted to enable wireless charging, a technology being trialled in Phantom EE. The battery pack would be expected to last over three years were it to be used every day. Part of the programme however will be to test this assumption in a real world environment and deliver a more robust answer to the question of battery lifespan.

The standard fuel filler cap has been replaced by a design featuring a clear window, displaying the RR logo and 102EX motif. The window frames rear-mounted, tricolour LEDs which present the car's charging status.
- 24. OVERALL VERDICT The car is trying to research into possible future for automobile industry. With oil reserves exhausting rapidly there is urgent need to develop sustainable power sources . Although solar is a possibility it has very narrow scope in present times. Thus electric drivetrain is a possible path in the future Rolls Royce means” no compromise “. With their 102 EX they are stepping into the modern era for the company . The 102EX is also reflecting their heritage of cars . With no compromise in power and comfort. It runs on most efficient lithium batteries and also uses 96 of them , the highest used in any battery car.Coming to comfort the interiors are designed using corinova leather .It is a special type of vegetable tanned leather. Interiors also include wood finish. Thus the car is completely a blue print for the future rolls. The only question is there any compromise in quality when compared to the petrol versions. Well to know that you would have to get your hands on one of them.
Notas do Editor
- Rolls royce stands for perfection. It is a symbol of quality and exclusiveness. rolls are built with out any compromiose in style comfort or power. Each model has a personality of its own, but all share the same powerful presence. When a rolls drives by the world stands still.
- The Rolls-Royce 10 hp was the first car to be produced as a result of an agreement of 23 December 1904 between Charles Rolls and Henry Royce , [1] and badged as a Rolls-Royce. The engine is a water-cooled twin cylinder of 1800 cc enlarged to 1995 cc on later cars, with overhead inlet and side exhaust valves, [3] and based on the original Royce engine but with an improved crankshaft. The power output was 12 hp (9 kW) at 1000 rpm. The car has a top speed of 39 mph (63 km/h)
- Some of rolls earlier models
- Present day Rolls royce….phantom 239.8 in
- Phantom has a rare sense of scale and occasion that makes it a truly modern interpretation of a Rolls-Royce. The grille and Spirit of Ecstasy immediately mark out Phantom. The 2:1 wheel-to-height ratio is fundamental to this as are the coach doors. The gentle downward curve of the roofline and upward sweep of the lower body line suggest movement even when the car is stationary. Just as Phantom's presence is quietly authoritative, the delivery of power from the direct-injection V12 engine is equally impressive. At 70mph over 90% of the power is available in reserve, making for effortless acceleration. Combined with the electronically controlled six-speed transmission, pressing the accelerator gives the driver a feeling of smooth, endless acceleration from standing or at speed.
- The baby rolls…ghost 212 in
- Ghost is the essence of Rolls-Royce in its simplest, purest form. Every inch delivers on the power of simplicity. The classic Rolls-Royce proportions are all present and correct: the 2:1 ratio of the height of the wheels to the height of the body; the long wheelbase and bonnet; the short overhang at the front and long overhang at the rear. Exterior Designer, Andreas Thurner says "…it looks natural, not styled". Its powerful presence leaves no doubt that it's cut from the same cloth as the rest of the marque - exactly what we set out to achieve.
- The current debate about the future of this company
- BATTERY PACK Phantom EE is thought to have the largest passenger car battery in the world. Peak current is 850A, delivered at 338V DC. Overall capacity is 71kWh. The pack is comprised of large-format NCM pouch cells. NCM (Lithium-Nickel-Cobalt-Manganese-Oxide) is a variant of lithium-ion chemistry that has particularly high energy and power densities. The Phantom EE battery pack houses five modules of cells, a 38-cell module, a 36-cell module, and three smaller ones of ten, eight and four arranged in various orientations within an irregular shaped unit. This resembles the overall shape of the original engine and gearbox. Each of the 96 cells was individually tested before assembly into modules to determine their characteristics and capacity. Sub-assemblies were further tested under load to verify that the power connections between each cell perform to specification. The electronic sensing units for each group of cells were tested and calibrated prior to assembly and put through a rigorous temperature cycling regime designed to provoke failure of weak components. The main electronic box, which contains the switching and control gear, was tested in isolation from the other components to verify correct operation. Three separate charger units (3kW each) are fitted to the battery, which allow both single-phase (20 hours) or three-phase charging (8 hours); for a passenger car this is unique. A fourth induction charger is also fitted to enable wireless charging, a technology being trialled in Phantom EE. The battery pack would be expected to last over three years were it to be used every day. Part of the programme however will be to test this assumption in a real world environment and deliver a more robust answer to the question of battery lifespan. INDUCTION CHARGING Concerns about lack of available re-charging infrastructure in towns and cities are well documented and critics of electric motoring point to the additional inconvenience of trailing cables connected between power source and vehicles. To present Rolls-Royce owners with a vision of a potential solution to these problems, Phantom EE is testing a technology called induction charging. This allows re-charging to take place without any physical connection, delivering greater convenience for owners and hinting at the potential for a network of remote charging facilities. There are two main elements to induction charging; a transfer pad on the ground that delivers power from a mains source and an induction pad mounted under the car, beneath Phantom EE's battery pack. Power frequencies are magnetically coupled across these power transfer pads. The system is around 90 percent efficient when measured from mains supply to battery and it is tolerant to parking misalignment. For example, it is not essential to align the transmitter and Phantom receiver pads exactly for charging to take place. While pads are capable of transmitting power over gaps of up to 400mm, for Phantom EE the separation is in the region of 150mm. The coupling circuits are tuned through the addition of compensation capacitors. Pick-up coils in the receiver pad are magnetically coupled to the primary coil. Power transfer is achieved by tuning the pick-up coil to the operating frequency of the primary coil with a series or parallel capacitor. The pick-up controller is an essential part of the technology because it takes power from the receiver pad and provides a controlled output to batteries. It is required to provide an output that remains independent of the load and the separation between pads. Without a controller, the voltage would rise as the gap decreases and fall as the load current increases. The transmitter pad has been constructed to shield magnetic fields to prevent EMI egress to bystanders and the system operates well within internationally agreed limits.
- EXTERIOR RE-CHARGING POINT Re-charging is undertaken with a plug and five-pin socket which takes the place of the normal fuel filling mechanism for Phantom.The standard fuel filler cap has been replaced by a design featuring a clear window, displaying the RR logo and 102EX motif. The window frames rear-mounted, tricolour LEDs which present the car's charging status. On start up, the socket is bathed in blue light. This begins to flash as charging commences. When completely charged, the display turns green, then flashing green as the solenoid is disengaged. A potential fault in the system is indicated by either constant or flashing red light. Charging can be halted via a switch located adjacent to the plug. The process can also be operated inside the vehicle using controls accessed beneath the centre console, for example when induction charging is taking place.
