The increasing use of plug-in hybrid and electric vehicles has led to the need for charging infrastructure not only at the residential level, but also in semi-public settings such as businesses, including offices, factories, and retail stores.
Businesses can offer vehicle charging points for a number of purposes. One may be to provide a service to their employees, which can help to attract and retain talent. Another is to provide the option to their suppliers or customers, thereby helping to attract new customers, either for free or by charging for the energy supplied. Regardless of their objective, they will be able to take advantage of the space available in their car parks or material collection areas.
To provide this type of service, companies require:
- Energy efficiency and security: optimal distribution of available energy.
- Simplicity: solutions that do not require unattainable resources.
- Restricted access: to prevent charging by outside users.
- Monitoring and management of loads: including billing, if any economic benefit is sought.
VISIOTECH, together with its supplier RAEDIAN, offers the NEX and GEMINI ranges, designed for semi-public and corporate environments. These solutions allow the installation of several chargers in series, ensuring that energy is distributed evenly according to demand, thus guaranteeing a safe and uninterrupted service.
INTEGRATION OF SEVERAL ELECTRIC VEHICLE CHARGING POINTS
In businesses with limited power capacity, charging solutions must be smart in order to guarantee a safe and efficient power supply to all charging points.
As in residential environments, load balancing is key for businesses. In installations with more than one charging point, Dynamic Load Balancing (DLB) is applied, which adjusts the power supplied based on the available energy and the number of vehicles being charged.
This system offers:
- Safety in the installation: providing energy without affecting the company's electrical system.
- Reliable service: satisfied customers, suppliers and employees, as no vehicle is left uncharged.
- Economic savings: no need to oversize the installation or increase contracted power.
How is load balancing carried out?
Load balancing is carried out by measuring the available energy using a Smart Meter with current clamps, which sends data to the chargers to automatically adjust their power. One charger acts as the leader, connected to the meter via LORA (wirelessly) or by long-range RS485 cable, and transmits the information wirelessly to the others, covering a distance of up to 100 metres.
This allows all vehicles to be charged efficiently, distributing the available energy evenly across each charger. In addition, it is possible to control access using RFID to prevent unauthorised use.
Visiotech’s solution: RAEDIAN’s NEX and GEMINI chargers
The NEX range from RAEDIAN is the ideal solution for installations with more than one electric charging point, making it perfect for business environments thanks to its features:
- Integrated software for equitable power balancing: allows management of up to 21 devices connected in series via a meter, ensuring efficient energy distribution.
- Quick commissioning of the system through the RAEDIAN INSTALL app.
- Remote management and monitoring of the installation via the NEBULA portal.
- RFID reader and cards included for access control and payment management.
The GEMINI range from RAEDIAN expands on the features of the NEX range, making it ideal for certain businesses by offering the following additional features:
- Dual socket: allows two vehicles to charge simultaneously at the same point, optimising space.
- Flexible payment options: via RFID (indirect payment) or Payter (direct payment).
- Even more accurate metering: equipped with a certified dual MID meter.
- Modern, vandal-proof design: with button panel and 100% advertising display.
In addition to being a solution for end users, electric mobility is also a reality for businesses. As a distributor of RAEDIAN, Visiotech offers efficient solutions that can help you implement this technology easily and professionally.
