DC charging infrastructure for retail, shopping centers and restaurants: a new opportunity for e-mobility

In the context of the energy transition, large retail chains, shopping centers, restaurants, and all businesses characterized by customer dwell times of one to two hours represent ideal locations for the installation of widespread public charging infrastructure.

Designing these solutions today requires an integrated approach capable of combining industrial power electronics, compact design, and smart software for managing available power, user authentication, and service billing. The goal is to make the most of customer dwell time through medium- and high-power direct current (DC) charging stations.

The main technologies available

At the hardware level, the market offers two major families of solutions.

On one hand, there are the leading manufacturers of power electronics and photovoltaic inverters, who have extended their industrial expertise to the development of high-efficiency DC charging stations. These systems integrate advanced conversion modules capable of operating in synergy with photovoltaic plants and C&I-sector BESS storage systems, including through direct current (DC) connections.

On the other hand, the market offers solutions developed by companies specializing in electric mobility, automation, and charging infrastructure management.

Centralized architectures and compact systems

The architectures currently available are mainly divided into two configurations.

The first involves centralized power conversion through a single high- or very-high-power unit, capable of dynamically managing available energy and distributing it to satellite dispensers with a minimalist design. This solution optimizes use of space and preserves the aesthetics of commercial parking areas.

The most advanced manufacturers also incorporate large anti-vandal touchscreens, contactless credit card readers compliant with the latest European AFIR regulations, and LED lighting systems that allow the operating status of charging points to be identified at a glance.

When available space is limited, the choice can shift toward compact, lightweight DC devices, drawing on experience gained in the residential and semi-public charging sector. These solutions offer refined aesthetics and high connectivity, and can be wall-mounted or installed on double-sided poles, minimizing visual impact.

Smart load balancing and interoperability

The real strategic element of a multi-point infrastructure lies in its dynamic load-balancing algorithms.

The integrated software continuously monitors the power available at the connection point and distributes it optimally among the various charging points, also taking into account the consumption of other loads present at the site.

When the building’s energy demand increases, the system automatically adjusts the power delivered without interrupting ongoing charging sessions, ensuring service continuity and maximum efficiency in the use of available resources.

The adoption of open, standardized communication protocols, such as OCPP and Modbus, also ensures full interoperability with payment platforms, apps from major electric mobility operators, and SCADA systems dedicated to managing the energy of the entire complex.

Users can thus start a charging session via QR code, corporate cards, dedicated apps, or loyalty programs linked to the businesses.

A strategic investment for the retail sector

Adopting DC charging infrastructure allows shopping centers, restaurants, and retail businesses to turn customer dwell time into an opportunity for added value.

The result is a modular, scalable infrastructure that integrates seamlessly with the building’s energy balance, capable of supporting the growth of electric mobility and generating new value-added services for customers.
