How to install a company wallbox: technical and regulatory requirements

The installation of acompany wallboxhas become a priority for many businesses that want to offer charging services toemployees in the company car parkor managefleets of electric vehicles(company cars, commercial vehicles, company vehicles).

However, the process requires a thorough understanding oftechnical and regulatory requirementsto ensure a safe, compliant, and high-performance installation. In this comprehensive guide, we analyze every aspect to consider for companies with offices, operational sites, and reserved parking lots.

Who is this guide for?

This guide is primarily intended forB2B companies with offices, employees, and company fleets, where access to charging is limited to a defined number of users (employees, collaborators, company vehicles, guests). These are contexts with:

• Controlled flows:users identified by badge, RFID, or app
• Expected usage:scheduled recharges during working hours
• Internal management:tracking consumption by cost center or reimbursements
• Plannable maintenance:with less critical intervention times

Activities with greater exposure to the public: different considerations

If, on the other hand, you managehotels, shopping centers, restaurants, outlets, accommodation facilities, or parking lots open to the public, wallboxes can still be a valid solution, but withdifferent technical and management requirements:

• High and variable flows:payment systems must be suitable
• Higher power ratings: DC powerful AC DC solutions are preferable
• Critical reliability:even higher uptime to avoid negative reviews from customers/guests
• Multilingual support:service that is also easy to use for international customers

For these businesses, the choice between wallboxes and public charging stations depends onthe number of usersand thebusiness model. A boutique hotel with 20 rooms may opt for wallboxes dedicated to guests, while a shopping center with hundreds of daily visitors may require DC infrastructure.

In this guide, we will focus on the needs of traditional B2B companies, but many technical and regulatory principles also apply to businesses with an external audience.

Why install a company wallbox?

There are many reasons why a company should install charging points at its premises, ranging from benefits for people to operational optimization and strategic positioning.

From ahuman capital perspective, offering charging to employees has become anincreasingly sought-after benefitthat directly impacts satisfaction and retention. Employees can arrive at the office, connect their car, and leave at the end of the day with a full battery, completely eliminating the need to search for public charging stations in the evening or on weekends.

This benefit naturally extends tocustomers, partners, and business guests as well: offering charging during meetings or visits conveys an image of a modern company that is attentive to the needs of its stakeholders, strengthening professional relationships.

From anoperational and economic standpoint, for those who managecompany fleets(company cars, commercial vehicles, vehicles for agents or technicians), having charging points on site represents aconcrete competitive advantage.

Costs are drastically reduced compared to traditional fuels, vehicles are always ready for use, and there is no need to plan stops at public stations during the work shift, simplifying logistics and increasing productivity.

Finally, from astrategic and reputational standpoint, a well-designed charging infrastructure effectively communicates the company's commitment tosustainability and innovation, contributing to the achievement ofESG(Environmental, Social, Governance)objectives, which are increasingly central to the assessments of investors, corporate customers, and business partners.

It is no longer a "nice to have," but rather an element that distinguishes forward-thinking companies from the competition.

Basic technical requirements

Before proceeding with installation, a preliminary assessment of the electrical system by a qualified technician is required. This step is crucial to verify the available power of the company's meter and determine whether it is sufficient to power one or more wallboxes without causing overloads.

Alternatively, you can consider installing a dedicated POD managed by the charging partner operator: in this case, a separate meter is installed, registered to the operator and dedicated exclusively to wallboxes, which manages energy supply and administrative aspects, providing the company with consumption reports.

The choice between an existing company POD or a dedicated POD depends on the contractual agreements and the service model chosen. If you opt for the existing company POD and the available power is insufficient, you will need to request an increase from the distributor.

The choice of wallbox depends on specific requirements:

• 7-7.4 kW wallbox (single-phase):ideal for charging throughout the working day or in situations where the vehicle remains parked for many hours (full-time employees)
• 11 kW wallbox (three-phase):recommended for company fleets or when faster charging is required (vehicles that leave and return several times a day)
• 22 kW wallbox (three-phase):for fast charging requirements, requires a three-phase system and adequate contractual power

It is essential to choosewallboxes that are certifiedaccording to European standards (CE mark) and equipped withintegrated protectionssuch as type A EV residual current devices (with DC current detection DC 6mA) and leakage current management systems.

Many modern wallboxes also includesmart features, such as Wi-Fi or 4G connectivity forremote monitoringandaccess management via RFID or apps, which are essential for controlling who charges and tracking consumption per employee or company vehicle.

Italian regulations: what the law says

In Italy, the installation of company wallboxes is regulated byLegislative Decree 257/2016andLegislative Decree 48/2020, which establish specific obligations:

• Newly constructed non-residential buildings with a surface area > 500 m²:obligation toprovidedrainageinfrastructurefor at least20% of parking spaces.
• Non-residential buildings with 20 or more parking spaces:requirement toinstall at least one charging pointby January 1, 2025

For existing buildings that do not meet these requirements, there is no obligation, but the installation must still comply withspecific standards.

From a technical standpoint, the installation must comply with:

• CEI 64-8 standard (Section 722):regulates electrical systems for charging electric vehicles, specifying differential protections and dedicated lines.
• CEI EN 61851 (IEC 61851-1) standard:specifies electric vehicle charging systems and operating modes
• DM 37/2008:regulates the design and construction of electrical systems in Italy

Installation must be carried out exclusively by acertified installer, who will issue thedeclaration of conformity (DiCo)required by law.

For systems with a power rating exceeding 6 kW,design by a qualified technician is also required. Operating without this certification exposes the company to significantlegal and insurance risks.

Step-by-step installation process

The installation process consists of several stages that requirespecialist skillsand must be followed to ensure safety and regulatory compliance:

1. Site inspection and technical design:a professional must assess the existing electrical system, calculate energy requirements, identify the optimal location for wallboxes considering the distribution of electrical loads, and design the intervention in compliance with regulations.

2. Handling paperwork:if necessary, communications with the municipality, requests for authorization from the network operator for the power increase, and coordination with the energy supplier must be handled. This phase can be complex and slow down the project if not managed correctly.

3. Certified physical installation:the installer mounts the wallboxes, makes the electrical connections with the necessary protections, installs any additional electrical panels, and checks the grounding. Any error at this stage can compromise the safety of the entire system.

4. Testing and certification:all electrical parameters and device safety are checked, andcomplete compliance documentation(DiCo) is issued, which is essential for any inspections or insurance coverage.

5. Smart system configuration:for smart wallboxes, it is necessary to configure connectivity, management apps,controlled access systems(RFID, codes, etc.) and consumption reporting, operations that require specific IT skills.

Multi-point management and advanced systems

For companies that needmultiple installations, the complexity increases exponentially.Dynamic load management systemsintelligently distribute the available power among all active wallboxes, preventing overloads. These systems require careful design, programming of balancing parameters, and integration with the existing electrical infrastructure.

The configuration can includedifferentiated priorities(for example, prioritizing company fleets over employees to ensure vehicle operability), time slot booking systems,consumption tracking by cost center, and detailed reporting for internal accounting or employee reimbursements. Each element requires specific skills to function properly.

Costs and investment models

The costs for installing a company wallbox vary greatly and depend on: the type of wallbox, the number of charging points, the condition of the existing electrical system, the need for civil works, and the chosen contract model. The investment consists of several items.The hardwareranges from a few hundred euros for basic models to several thousand for professional smart solutions.

Certified installationincludes specialized labor, electrical materials, protective devices, and a declaration of conformity.Infrastructure upgrades(electrical panel upgrades, civil works, power increases) are often the most unpredictable item.Load management systemsfor multiple installations require additional investment but optimize available power.

The company can choose to purchase the hardware independently and manage all stages of installation, or rely on a specialized charging partner that offers complete packages or different partnership options.

Powy, for example, offers three formulas to meet different business needs:

Direct purchase: turnkey solution with full ownership of the infrastructure. Powy from hardware selection to certified installation, ensuring management, ongoing maintenance, and intelligent software for optimization. Includes the possibility of generating revenue by opening public access.

Zero-investment partnership: Powy all hardware, installation, and start-up costs. The company receives complete management with no operating expenses and aguaranteed revenue streamwith a percentage of each charging session. Scalable model for long-term growth.

Shared co-investment: joint investment withtransparent, contractually definedparticipation percentages. Equal sharing of risks and benefits, Powy management Powy , andrevenue streambased on a percentage of charging sessions.

The choice depends on your priorities: the autonomous approach offers maximum flexibility but requires internal expertise, turnkey purchase guarantees comprehensive support while maintaining ownership, partnership eliminates initial risk, and co-investment balances financial participation and economic results.

Maintenance and technical support

After installation, the infrastructure requiresperiodic scheduled maintenanceto ensure safety and efficiency over time. Checks must verify the status of electrical connections, the functioning of protections, the integrity of cables, andfirmware updatesfor smart wallboxes.

Without a maintenance contract with specialized operators, any malfunctions can causelong periods of downtime, creating disruption for employees and fleets.

Remote 24-hour monitoringallows anomalies to be identified before they become critical failures, but requires dedicated platforms and qualified technical assistance ready to intervene.

FAQ: Frequently asked questions about company wallboxes

Do you need municipal authorization to install a company wallbox?
In most cases, municipal authorization is not required if the installation takes place on private company property and does not involve structural changes visible from the outside. It may be necessary to notify the network operator if an increase in meter power is required. In particular contexts (listed buildings, areas subject to specific regulations), it is advisable to check with the local municipality.

Can I install multiple wallboxes at the same time?
Yes, it is possible to install multi-point systems with dynamic load management. These systems intelligently distribute the available power among all active wallboxes, preventing overloads on the company's electrical network. It is the ideal solution for companies with electric fleets or many employees who need to recharge.

What happens if my company's meter does not have sufficient power?
If the available power is insufficient, there are two options: request an increase in power from the energy supplier (which takes 2-4 weeks) or install a dynamic load management system that automatically balances the power between company utilities and wallboxes, making the most of the existing power without the need for increases. Alternatively, you can consider installing a dedicated POD managed by your charging partner operator from the outset, which allows you to completely separate wallbox consumption from business consumption.
