Unpacking the basics of EV charging infrastructure

In the first episode of ‘Watt’s up with energy?’, host Georgia Knapp and gridX Solution Engineer Lars Rheinemann unpack EV charging, charging infrastructure and smart charging – from home to public sites – and how software makes e-mobility reliable, renewable and grid-friendly.

What you’ll learn in this episode

What “charging infrastructure” really means

Charging infrastructure is everything needed to recharge an EV: the charge point, the grid connection, and the software for authentication, payment, and management. Lars explains how these layers work together at home and in public, and why reliable coverage is essential for adoption and driver confidence.

Smart charging: efficiency, renewables and the grid

Smart charging schedules EV charging to fit renewable generation and local constraints. With energy management, drivers can prioritize solar power, shift to off-peak tariffs and avoid overloading sites. The result: lower costs, fewer bottlenecks and charging infrastructure that stabilizes the grid instead of straining it.

Home vs. public EV charging (and that range anxiety)

Most cars sit parked about 23 hours a day – ideal for controlled EV charging at home or work. Public sites prioritize speed, but home charging delivers flexibility and savings. Lars unpacks common fears, from unplugging myths to range anxiety and how better site planning and availability address real-world needs.

Bidirectional charging and the role of home batteries

EV batteries are large, flexible storage assets. With bidirectional charging, energy can flow from the car to the home, reducing grid demand at peaks and leveraging cheap or solar power. Lars outlines when this complements (or can’t replace) a stationary battery, depending on driver schedules and availability.

Quotes from Lars: Add chargers where they’re need, not where it’s easiest

“Smart charging is about timing – aligning EV charging with renewable availability and local limits to cut costs and support the grid.”

“Charging infrastructure spans hardware, software and the grid. Deployment only works when we balance cities, rural areas, home and workplace needs.”

“We must add chargers where drivers actually park, not just where it’s easiest to build.”

“An EV battery can support the home through bidirectional charging, but it won’t always replace a stationary battery – availability and routines matter.”
