• Improvements to 90 percent of the major component parts of the PHEV system that gives stronger EV flavor.
• EV cruising range increased to 65.0 km (from 60.2 to 60.8 km; JC08 cycle);
• S-AWC performance increased and two new drive modes added;
• Driving quality improved with changes to dampers and steering gear.
Packs a powerful punch with higher powered density delivered in a lighter, smaller cost effective package. Combining the inverter and converter eliminates extra cables, connections, hoses and housings.
A reduced overall mass and size makes integration simple and less expensive.
Modular concept allows for double-sided cooling for increased scalability.

Car components as an affordable solution
Bosch supplies an inverter and the relevant vehicle control unit (VCU). The separate motor generator (SMG) is available for installation as a complete electric motor, or the active components – rotor, stator, and resolver – can be integrated into the axle. A battery system that can store the energy is also required.
Induction motor is the most widely used type of e-motor. An induction motor like any other rotating machine consists of a stator (the fixed part) and a rotor (the moving part) separated by air gap. The stator contains electrical windings housed in axial slots. Each phase on the stator has distributed winding, consisting of several coils distributed in a number of slots. The distributed winding results in magnetomotive forces (MMF) due to the current in the winding with a stepped waveform similar to a sine wave. In three-phase machine the three windings have spatial displacement of 120 degrees between them.
For vehicle applications, recent developments in low-cost inverters have made variable-speed operation possible for traction drives.
There are few recent improvements to the AC motor for vehicle applications.
One of these is the use of a copper rotor instead of aluminum. Depending upon the size of the motor, the use of copper can increase the efficiency of an AC induction motor by one to three percentage points. Although this may seem like a small increase, it is significant in reducing the losses generated by the motor, easing thermal management. Depending on the vehicle, this could also add some distance to all-electric driving range as well.
