The electric vehicle (EV) market is expected to jump from 3.2 million units in 2019 to nearly 27 million units by the year 2030. Major players in this industry are expected to invest more than $350 billion in the near future to grow the electric vehicle market.
Wolfspeed understands the technological challenges that EVs present for engineers, especially when it comes to power and EV charging solutions.
A Charging Problem
While electric vehicles are becoming more commonplace, many consumers continue to have concerns about range and charging capabilities. For decades, the consumer driving experience has been powered by fossil fuels, and refueling meant a quick stop at the gas station to top off the tank. The prospect of a lengthy charging process to keep your car traveling down the road is a massive deterrent.
Enter On-Board Battery Chargers
On-board battery chargers are the key to keeping EVs powered—they take AC current from the charger unit and convert it to DC power to recharge the battery. They are also often capable of harvesting kinetic energy from the vehicle itself to provide additional charge. But traditional silicon has made these systems very limited in both their output and speed.
Wolfspeed is changing that.
A New Level of OBC Capability, Powered by Wolfspeed SiC
Traditional silicon has limitations, particularly when it comes to high-power applications like those of on-board charging (OBC) systems. But Wolfspeed silicon carbide (SiC) is uniquely capable of handling higher voltages and taking on even the most challenging of power applications.
Through Wolfspeed SiC, automotive innovators can realize:
- Up to 30% lower losses
- Up to 50% greater power density
- Up to 30% fewer components, leading to lower overall system cost and reduced vehicle weight
Wolfspeed silicon carbide also maximizes the potential of both unidirectional and bidirectional OBC capabilities. This means automotive manufacturers can design systems that can both receive energy from the grid and give it back, helping to stabilize the electrical grids of the future and create a more sustainable growth path for tomorrow’s EVs.
