As the world shifts towards sustainable transportation, the demand for efficient EV charging solutions is growing. With governments implementing stricter emissions regulations and the number of EVs on the market increasing, the need for faster and more reliable charging technologies has never been more pressing.
Another goal of high-power chargers is to reduce charging time, making electric vehicles comparable to combustion engine cars. To achieve this, designers must consider reliability, efficiency, cost, secure data, and communication.
To address these issues, Infineon's comprehensive portfolio of high-quality power semiconductors, microcontrollers, gate drivers, and more, empowers the development of energy-efficient DC EV chargers. From kilowatts to megawatts, our broad range of solutions, combined with expert technical support, enables the creation of innovative and reliable charging systems.
Accelerating EV Adoption with High-Power Charging
Encouraging drivers to make EVs their primary means of transportation relies heavily on finding ways to extend their range. While carmakers work on more efficient batteries, equally important is building up a powerful, convenient, and accessible charging infrastructure. This need for more range and reliable infrastructure translates to greater demand for more power as fast as possible.
The Power of High-Speed Charging
High-power DC charging systems are the key to unlocking this demand. With the ability to add 200 km to a battery in just seven minutes, drivers can quickly and easily top up their charge on the go. This technology is crucial in eliminating "range anxiety" among drivers and further encouraging EV adoption around the world.
Extended Range and Fast Charging: Eliminating Range Anxiety
To encourage widespread EV adoption, it's also essential to address range anxiety by extending the driving range and building a convenient, accessible charging infrastructure. High-power DC charging systems are the key to achieving this, allowing drivers to add 200 km to their battery in just seven minutes. By providing fast, efficient, and accessible charging, we can eliminate range anxiety and make EVs a more viable option for drivers worldwide.
