Rolls-Royce Testing Electric Phantom for World Tour

Rolls-Royce brought the Phantom Experimental Electric prototype to the independent MIRA research facility in Warwickshire this week for a series of laboratory-controlled temperature tests, designed to measure the readiness of the 102EX for different climatic conditions.  Engineers were keen to learn how high temperatures and humidity levels affect battery performance while in use.

“The tests have furnished us with important data about the effects of heat and humidity on 102EX’s battery and management systems,” commented Andrew Martin, 102EX chief engineer. “For example we are clear that the battery management system, which maintains safety and optimal operation of individual cells, will inhibit charging at extreme temperatures. Practically speaking, this may mean finding locations in which the car’s cells can cool after test drives before a re-charge can begin.”

The results show the car’s 96 cells will continue to operate at temperatures as high as 50 degrees and in relative humidity as low as 30%.

102EX began its tour in May with events at the home of Rolls-Royce in Goodwood. This was followed by drives in London and the South East of England, then Manchester and Edinburgh. The final drive is scheduled for Birmingham on 5 July 2011, before the car departs for international events in the following locations:

• Asia-Pacific Region: Singapore and Beijing (late July and early August 2011)
• North America: Pebble Beach, LA (Tuesday 16 to Sunday 21 August 2011)
• Europe: Regional tour (September 2011)
• Asia-Pacific Region: Japan (final week of September 2011)
• Middle East: Dubai (October 2011)
• North America: New York, Los Angeles Motor Show, Las Vegas, Florida and Art Basel, Miami (November and early December 2011).

The Phantom Experimental Electric will also be presented at the Festival of Speed this weekend, starting with exclusive hill climbs on Thursday 30 June 2011 as part of the Moving Motor Show.
