Engineered for high efficiency, complete MOBI.E system interoperability, and seamlessly adaptive single/three-phase dynamic load management.
Navigating regional grid topologies, municipal decarbonization, and private infrastructure expansion.
As the academic, medical, and technological heart of Portugal's Centro Region, the municipality of Coimbra represents a critical focal point for EV charging infrastructure development. Nestled along the Lisbon-Porto transport corridor, Coimbra is undergoing a rapid transition toward zero-emission mobility, fueled by municipal directives, University of Coimbra carbon-neutral initiatives, and expanding industrial parks such as iParque.
Residential electric vehicle adoption in districts such as Solum, Celas, and Santa Clara has accelerated demand for high-reliability, intelligent AC home EV charging stations. Unlike dense urban centers, Coimbra's suburban layout presents a vast market for private residential wallboxes (7.4kW single-phase to 22kW three-phase) that interface seamlessly with local grid configurations regulated by E-Redes and ERSE.
Electrical residential installations across Coimbra predominantly feature 230V single-phase grid connections rated between 3.45 kVA and 13.8 kVA, alongside modern residential builds operating on 400V three-phase architecture. This dual grid typology creates specific engineering demands for imported EV chargers.
Furthermore, given Portugal's abundant solar irradiance—averaging over 2,800 hours of sunshine annually—homeowners across the Mondego valley are increasingly deploying distributed solar PV arrays. Modern EV charging stations must feature hardware-level dynamic load balancing (DLB) and smart solar surplus charging capabilities (ECO and Fast modes) to optimize self-consumption and prevent costly breaker trips.
Whitepaper-level depth on power electronics, protocol standardizations, and grid stability features.
Our smart AC chargers utilize external CT transformers or RS485 energy meters to measure real-time household energy consumption. The internal MCU automatically modulates the charging current (from 6A to 32A within milliseconds) based on available residual grid capacity, eliminating overload risks without requiring grid capacity upgrades from E-Redes.
Ensuring full compatibility with management backends and operator networks across Europe. Support for JSON-over-WebSockets enables seamless remote diagnostics, automated billing integration, over-the-air (OTA) firmware updates, and interoperability with MOBI.E management platforms or private operator management software.
Equipped with built-in Type A AC 30mA residual current protection coupled with 6mA DC smooth leakage detection (IEC 62955 compliant). Eliminates the need for expensive upstream Type B RCD installations, reducing total system installation cost while satisfying Portuguese electrical safety standards.
Engineering Benchmark: All EnerNova AC Charging Stations undergo rigorous thermal stress testing ranging from -30°C to +55°C, ensuring robust operation under intense Mediterranean summer heat in inland Portugal.

Tailored deployment blueprints for suburban residences, multi-dwelling units, tech parks, and hospitality venues.
Single-family detached homes in Coimbra's residential neighborhoods frequently utilize rooftop solar PV arrays. Our smart wallboxes integrate directly with residential solar inverters (via Modbus RTU / Ethernet TCP) to execute solar surplus tracking. Homeowners can select "ECO mode" to charge exclusively using zero-carbon solar energy, dramatically shortening payback cycles.
Retrofitting legacy apartment underground garages presents electrical supply challenges. Utilizing Master-Slave dynamic load distribution architecture, up to 32 EnerNova AC chargers can share a single main electrical supply line, dynamically scaling power down during peak domestic hours and accelerating charging overnight.
Technology enterprises requiring employee workplace charging benefit from dual-gun 14kW/22kW floor-standing or wall-mounted AC charging stations. Equipped with MID-certified energy meters and RFID card access control, corporate administrators can seamlessly track energy utilization by department or generate automated reimbursement reports.
Hotels, rural tourism estates (Turismo Rural), and commercial destinations along the Mondego River require robust, aesthetically striking EVSE. Weatherproof IP65 wallboxes with customizable front glass plates offer premium branding opportunities while providing visiting EV drivers with rapid, reliable overnight AC charging.
