In a world where renewable energy is on the rise, and electric vehicles (EVs) are taking the streets by storm, we're faced with a thrilling yet challenging reality. The sun doesn't always shine, and the wind doesn't always blow. Or both are fully up and provide even too much energy for the grid to digest which means that renewable energy isn't constant. On the flip side, EVs need to slurp up additional energy while charging. The result? A clear need for a solution that can dance with this unpredictability and keep our energy systems in harmony – enter the world of smart charging infrastructure.
Imagine a world where your EV isn't just a means of transportation but also a tiny powerhouse, contributing to the stability of the electrical grid. It's not just a dream; it's the promise of a smart charging infrastructure (SCI).
The catch? We're still on the runway, waiting for the green light. The transition to a smart grid isn't just about shifting charging times to when the grid is less busy. It's about creating a symphony where electric vehicles, energy storage systems, homes, and businesses play together harmoniously.
The hero in this story is Vehicle-to-Grid (V2G) technology, which allows EVs to give back to the grid when it needs it most. Picture your EV acting as a savior during peak demand, supporting the grid, and reducing waste from renewable sources. This is the potential we're tapping into, but it requires standards, regulations, and convincing all stakeholders that this can be done seamlessly and without harm.

Now, let's address the elephant in the room – the fear of battery degradation. You might be worried that smart charging will wear out your EV's precious battery. The truth is, with proper management, that's simply not the case. Battery’s health can be ensured by controlling factors like depth of discharge (DOD) and charge/discharge rates. Your battery can thrive in this smart charging environment, and you can benefit from it.
Infineon offers a comprehensive solution for smart charging infrastructure, encompassing power management, system control, connectivity, security, sensors, and embedded processing. Their wide bandgap technologies, such as CoolSiC™ MOSFETs and CoolGaN™ transistors, reduce power losses, while additional power devices like TRENCHSTOP™ IGBTs and EiceDRIVER™ gate driver ICs complete the power stage ecosystem with our XMC™ industrial microcontrollers taking care of the control of the power conversion stages.. They prioritize security with the AURIX™ family, featuring an embedded Hardware Security Module (HSM), and the OPTIGA™ family, offering tamper-resistant security devices. Infineon also provides bidirectional connectivity solutions like AIROC™ wireless solutions and precise current measurement sensors in the XENSIV™ series, making them a leading semiconductor provider in the field of electric vehicle charging.
