Meanwhile, we keep on finding out more and more technical details of the 102EX - as it has been dubbed by Rolls Royce - with the most recent fact being related to the vehicle’s power source.
Specifically, the car is powered by Axeon’s battery system, which uses 96 lithium ion pouch cells that fit into the space normally occupied by the car’s conventional engine and transmission. There is reportedly no difference to the 50/50 weight balance between front and rear, helping maintain the car’s dynamic integrity.
The Axeon battery system is believed to be the biggest passenger car battery built in the world, both in terms of capacity and power, with 71kWh overall capacity and 388V DC nominal power. The peak current that can be delivered is 850Ah, 330Kw.
The cells used in this battery are 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. Being built into large format, high capacity cells allows packaging of the battery in a limited space and also provides high power output.
“We are delighted to partner Rolls-Royce Motor Cars in this unique market testing programme, which provides Axeon with the opportunity to demonstrate our advanced technology capability,” said Lawrence Berns, CEO of Axeon.
