As electrification continues to transform the transport sector, the demand for reliable and high-performance charging infrastructure for heavy-duty vehicles is growing rapidly. To meet this need, Schmees Energietechnik GmbH, a German electrical engineering company with over two decades of experience and early involvement in e-mobility since 2014, partnered with Sungrow to develop a modern charging park tailored specifically for trucks and commercial vehicles. The objective was not only to provide technical functionality, but also to create an attractive and seamless charging experience that could support large-scale adoption of electric transport.
Designing infrastructure for heavy-duty electric vehicles requires addressing a set of highly specific operational challenges. One of the primary requirements for Schmees was accessibility, ensuring that truck drivers could approach and charge their vehicles without the need to uncouple their semi-trailers. At the same time, the system needed to deliver exceptionally high charging power to meet the demands of modern e-trucks, while maintaining a high level of availability to support continuous operation in logistics environments. Beyond these functional requirements, the project also aimed to create a visually appealing and user-friendly charging environment that enhances the overall driver experience.
To meet these requirements, the project implemented the Sungrow IDC480E, a high-power satellite charging solution designed for demanding applications such as heavy-duty transport. The system enables ultra-fast charging with outputs of up to 470 kW through liquid-cooled cables, allowing it to fully support the capabilities of current-generation electric trucks, which typically reach up to 400 kW charging capacity. Its satellite architecture provides a high degree of flexibility, enabling the configuration of charging stations according to different use cases, whether for trucks, buses, or passenger vehicles. A key advantage of the system lies in its intelligent power distribution, which dynamically allocates available energy across multiple charging points. This ensures that each vehicle receives the highest possible charging power without unnecessary energy bottlenecks when several vehicles are charging simultaneously. In addition, the system can be seamlessly integrated into a broader energy ecosystem, including energy management systems, photovoltaic installations, and battery storage solutions, making it a future-ready infrastructure component.
Schmees is a Germany-based energy and electrical engineering company that has been driving innovation in sustainable energy solutions for over 20 years. Founded in 2004, the company combines technical expertise with practical implementation to deliver integrated energy concepts across industries, including e-mobility, energy storage, wind power, and grid technology. With a strong focus on quality, reliability, and future-oriented thinking, Schmees supports businesses in becoming more energy-efficient and independent from fossil fuels through end-to-end solutions, from planning and installation to operation and service.
