Compact Design for High-Performance Service
The new DC Wallbox 50 kW is a compact and high-efficiency charging solution for commercial sites, offering ≥ 96% efficiency in an ultra-compact format of only 25 cm depth. It enables simultaneous DC charging via two connectors, making it ideal for roadside parking, shopping centers, office buildings, and EV depots, without requiring major modifications to existing infrastructure.
This new generation integrates advanced features such as: Status indicators to easily guide the driver to an available charging point; an NFC bank card reader for pay-as-you-go (ad hoc) charging; certified energy meters; an innovative cable management system for simple, clean, and ergonomic connection.
Application Scenarios
The application scenarios illustrate how the charging network integrates with backend management and software applications. Charging Networks, serving [Parking], [Commercial Areas], and [Transport Hubs], connect to an EV Charging Network Management System. This system facilitates remote access via a mobile application and supports Software Applications for Energy Management, Member and User Management, and Site/Building Management.
