There are 27 Lithium ion cells mounted under the bonnet in 9 groups of 3. A further 75 cells (25 groups of 3) are mounted at the back of the car. The total of 34 groups of cells gives 300Ah at a nominal 125.8 Volts (3.7 V per cell). The available power from the batteries is fed to a series wound dc motor via a 500 Amp controller. The controller and power relays are just in front of the batteries. The motor is beneath the batteries and drives the front wheels via a reduction gear and differential. Also situated under the bonnet is a dc voltage converter to supply the normal car electrical systems and to charge an emergency hazard warning and lighting battery.
