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
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.

TODAYS ROLLS ROYCE PHANTOM
GHOST
Can electric motoring deliver a true Rolls-Royce experience? 102EX is a
working test-bed designed to provide experiential feedback on alternative
drive-train technologies in ultra-luxury cars. The opinions of Owners, thought-
leaders and other contributors will drive the debate forward over the
coming year.
DESIGN
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.
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.
CHARGING1)Exterior Re-Charging point
2)Induction charging
Exterior re-charging
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The standard fuel filler cap has been replaced by a design featuring a clear window,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.
INDUCTION CHARGING
Mechanism
There are two main components of the induction charger•Transfer pad :it delivers power from the main source•Induction pad: it is mounted under the car beneath the phantoms battery pack
Working• . 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
• Separation between induction pads• The coupling circuits are tuned through the
addi tion of compensation capacitors.• 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.
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.
