The inverter, with a low weight of 11 lbs, is a unit derived from a high- performance model used in motor racing for electric vehicles, while the motor (46.3 lbs and a maximum rotation speed of 18,000 rpm) was developed by a partner following the technical specifications provided by Ducati. The entire system is based on a voltage of 800V (with a fully charged battery pack) to maximize the output of the electric powertrain, performance and range.
One of the most advanced technical solutions tested on the Ducati MotoE relate to the cooling system. The prototype components are in fact cooled by a particularly sophisticated and efficient liquid system with a double circuit designed to meet the different thermal needs of the battery pack and the motor/inverter unit. This guarantees the regulation of the extreme temperatures with important benefits in terms of consistency of performance but also in charging times. In fact, it is not necessary to wait for the battery pack to cool to start the process: the Ducati MotoE can be charged as soon as it enters the garage, and it takes about 45 minutes to recharge it up to 80% of its range.
The carbon fiber case of the battery pack also acts as a stressed part
of the chassis, similar for the Ducati Panigale V4 engine, with an aluminum monocoque Front Frame for the front area weighing 8.2 lbs. The rear is composed of an aluminum swingarm weighing 10.6 lbs with a geometry like that of the Ducati Desmosedici racing in MotoGP. The rear subframe, which integrates the
tail and the rider seat, is made of carbon fiber.
