Phantom experimental car hots up

Rolls-Royce Motor Cars has been carrying out a series of laboratory-controlled temperature tests on its Phantom 102EX Experimental Electric prototype

 

Rolls-Royce Motor Cars has been carrying out a series of laboratory-controlled temperature tests on its Phantom 102EX Experimental Electric prototype. Engineers investigated how extreme conditions such as high temperatures and humidity levels affect battery performance while in use, using facilities at the MIRA research facility in the UK. This information is critical as 102EX will shortly embark on a global tour that will take in markets such as the Middle East, Asia-Pacific and North America.

 

“The tests have furnished us with important data about the effects of heat and humidity on 102EX’s battery and management systems,” states Andrew Martin, the 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 tests have also reinforced expectations of the temperature range in which the car can be driven. In general, the car’s 96 cells will continue to operate at temperatures as high as 50°C and in relative humidity as low as 30%. This is well within temperature ranges expected while on tour, however battery performance will continue to be monitored by engineers as the car is taken to typically hot locations such as Dubai.

 

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, Edinburgh and Birmingham.

 

Following the prototype's successful lab tests, it can now move on to international events in Singapore and Beijing, Europe, Japan, Dubai, New York, Los Angeles, Las Vegas, Florida and Miami.
