Green Charging: Optimize PV Self-Consumption with Smart Charging Stations

The main challenge in solar charging lies in timing:

• PV generation follows the sun's position

• Vehicles are often parked at the company overnight

• Charging demands frequently exceed PV generation

• Fluctuating availability of solar power

The intelligent integration of charging infrastructure, PV systems, and energy management is revolutionizing green charging. Dynamic charging management automatically adjusts charging power to match available PV output, enabling demand-driven prioritization of individual charging points while considering planned departure times.

Battery storage systems act as flexible buffers, while predictive control leverages weather forecasts and typical usage patterns for forward-thinking charge planning and optimized storage utilization. Flexible load management coordinates multiple charging points, prevents peak loads, and seamlessly integrates into operational energy management through automatic power distribution.

The success of solar charging concepts relies on the seamless integration of all components:

Technical Integration:

• Communication-enabled charging stations

• Intelligent energy management systems

• High-capacity battery storage

• Standardized interfaces

Operational Organization:

• Defining charging priorities
