Expect to see many more electric vehicles (EV) on the road in the near future. The drastic price drop of batteries, rise in consumer appetite for more sustainable transportation options, and the availability of an increased number of EV options indicate improvements to the supply and demand for electric cars in recent years. By 2025, experts predict that car shoppers around the world will have the choice of more than 400 EV models, which could push EV sales to between 6 million and 11 million units.
This consumer demand for higher fuel efficiency and decreased vehicle emissions has accelerated the development of pure electric and hybrid electric vehicles (HEV). These vehicles depend on advanced electronically controlled systems working together across a wide range of operating conditions to ensure efficient performance, safety, and reliability.
Generally, vehicle electrification is focused on the powertrain driven by electricity and its auxiliary systems such as on-board and off-board charging systems, as well as wireless power transfer. However, vehicle electrification also means electrifying other components of the vehicle such as electronic power-assisted steering, electronic stability program, electronic traction control, intelligent light system, smart electromagnetic suspension, all-wheel drive, airbag deployment system, and more.
Increasing electrical content and complexity coupled with shorter design cycles require design teams to continually improve their design methods for mechatronic integration.
Read on to learn about the top five design challenges for electric vehicles and power semiconductors, and why a robust design flow can accelerate the growth of hybrid and electric vehicles going forward.
