INFINERGI
electric vehicle charging stations
The needs
The fast and growing expansion of electric vehicles, also facilitated by various forms of local and national incentives, led the global market to develop new types of devices dedicated to charge these vehicles. Multiple technologies and standard have been defined around this need, in order to create a wide ecosystem of hardware and software solutions that make the charging process of electric vehicles simpler, faster and globally available.
Given the strong growth of this market, the SEMAR group decided to invest in this sector by designing its own charging solutions, widely modular to adapt to multiple usage scenarios, such as individual residential users, corporate fleets or semi-public installations.
A careful study of the reference standards and market, followed by a comparative analysis of existing solutions, led to the definition of the minimum requirements that SEMAR group solutions should have met.
The challenges
- IEC 61851-1 AC wallbox and column, charging mode 3, cases B and C
- Charging power up to 22kW
- Suitable for private or semi-public usage
- Modular design to support multiple product variants and different scenarios
- Flexible and configurable charging mode, with dynamic load management and support for renewable sources
- Charging authentication via RFID card and APP
- Multiple wireless and wired connectivity
- Several local and remote management modes, both personal and centralized
- Single use or clustering
- IP grade for outdoor installations
The realization
INFINERGI è una famiglia di dispositivi di ricarica in AC per veicoli elettrici (Modo 3 EVSE – Electric Vehicle Supply Equipment), interamente progettata e realizzata dal gruppo SEMAR. La famiglia di prodotti INFINERGI si estende dal semplice ed economico dispositivo monofase per uso residenziale e personale, fino ai dispositivi trifase da 22kW con un’ampia gamma di funzionalità per utilizzi in ambienti semi-pubblici. La progettazione di INFINERGI è stata incentrata sull’ottenimento di un elevato grado di sicurezza (che eccede quanto richiesto dalle normative di riferimento), della massima flessibilità d’utilizzo e da un’ampia scelta di funzionalità smart.
