Power electronics is a very important and integral part of the powertrain unit of every electric vehicle. The power electronics of an electric drive system control the transfer of energy between the main components of electric vehicles, such as the battery, the electric motor, and the charger. The efficiency of a given electric drive is significantly influenced by the architecture of the power electronics.

Asymmetric tires combine two different tread types. At first glance, the tread shape differs between the right and the left. The asymmetric tyre design allows the tread to be split into two completely different parts. The first, rigid part ensures better handling and longer tyre life, while the second part dampens noise and sufficiently drains water away from the road.
