The new module – whose electric motor and power electronics are liquid-cooled – weighs less than 80 kilograms. It also features a new transmission-integrated electric parking lock function. Through the intelligent combination and integration of the system’s individual components, it was also possible to remove numerous connectors and cables, cutting costs even further.
The technical highlights include a range of 405 kilometres (provisional figures) and the rapid charging of the high-voltage battery from 10 to 80 per cent in less than 45 minutes. Customers can also choose between two different wheel bases.
With target figures of 2,000 PS of power and 1,700 Nm of torque, the Lotus Evija is the world’s most powerful production road car. Key to that exceptional power output is the 2,000 kW lithium-ion battery, supplied with its management system by Williams Advanced Engineering.
The battery pack is mid-mounted immediately behind the two seats and supplies energy directly to four powerful e-motors. This highly efficient system is the lightest, most energy dense, electric power package ever fitted to a road car. With a target weight of just 1,680 kg, it will be the lightest pure electric hypercar ever to go into series production.
The electric transmission in a parallel axis arrangement accelerates the front axle of the SUV. It also has an integrated parking lock for very high loads.
The first transmission stage is a planetary gear set, in which three planetary gears and a radially freed ring gear convert both torque and speed. The sun gear is positively locked with the motor’s rotor shaft via splines.
