Étude de cas : Déploiement progressif de la recharge pour véhicules électriques dans un grand condomínio brésilien

A large Brazilian condominium successfully implemented a phased EV charging project. This case study presents their replicable model. It provides a practical guide for property managers, boards, and residents. The project began by evaluating various Solutions de recharge pour véhicules électriques, including options from Fabricants de chargeurs de VE like TPSON and even considering chargeurs ev portables for initial flexibility. This process established a clear path for initial assessment, phased implementation of each Chargeur de VE, and sustainable cost management, creating a valuable blueprint for other residential communities.

Phase 1: Initial Assessment and Planning

A successful project begins with a solid foundation. The condominium board initiated Phase 1 by conducting a thorough assessment. This data-driven approach ensured that every decision was strategic, informed, and aligned with both current needs and future growth.

Identifying the Need

Designing the Resident Survey

The board first created a digital survey to measure resident interest. The survey asked simple questions: Did residents currently own an EV? Were they planning to purchase one in the next 1-3 years? What were their expectations for on-site charging? This initial step provided a clear baseline of immediate demand.

Analyzing Survey Results

Survey results showed a small but dedicated group of current EV owners. A much larger group indicated plans to purchase an EV within two years. This data confirmed that a proactive approach was necessary. The board understood that failing to act would soon leave residents without a crucial amenity.

Forecasting Future Demand

The board looked beyond simple survey data to forecast long-term needs. They used several professional methods to create a robust prediction model.

• Local EV Uptake: They analyzed the growth of EV ownership in their city and neighborhood. This helped predict the increasing need for residential charging solutions.
• Probabilistic Framework: The board also considered a more advanced model. This method used historical EV registration data, government mandates, and local census information to project future adoption rates within the building’s specific profile.

Technical Feasibility Study

Evaluating Existing Electrical Capacity

An electrical engineer evaluated the condominium’s main power panel and distribution system. The initial assessment revealed that the existing infrastructure could support a small number of chargers. However, a large-scale rollout would require significant upgrades.

Assessing Grid Connection and Limitations

The board contacted the local utility provider to understand the building’s grid connection limits. This conversation was critical. It clarified how much additional power they could draw without needing a costly transformer upgrade from the utility company.

Mapping Physical Space for Chargers

The property manager mapped potential locations for chargers. They identified spots in the common garage area for a pilot program. They also planned routes for conduits to individual parking spaces for future installations.

Identifying Structural Constraints

The team inspected the garage for any structural challenges. They checked wall integrity for mounting hardware and assessed ceiling heights for running new electrical conduits. This step prevented unexpected construction delays and costs later in the project.

Navigating Brazilian Regulations

Understanding ANEEL Normative Resolution 1,000

Navigating Brazil’s regulatory landscape was a key task. The board’s legal advisor reviewed ANEEL Normative Resolution 1,000, which governs EV charging in shared living spaces.

Key Takeaways from ANEEL Resolution 1,000:

1. Condominiums must permit residents to install individual chargers if they meet technical and safety standards.
2. Residents are responsible for the costs of their private charging stations.
3. Electricity can be billed individually via separate meters or collectively based on usage.
4. The condominium should create clear rules for installation and use to ensure fairness.

Securing Local Municipal Permits

The board confirmed with the local municipality that their planned electrical upgrades and charger installations would require specific permits. They started the application process early to avoid delays.

Researching Utility Company Rules (Enel, CPFL, Light S.A.)

Each utility company in Brazil (like Enel, CPFL, or Light S.A.) has its own rules for connecting new high-load equipment. The board studied their specific provider’s technical requirements for EV charging infrastructure to ensure full compliance.

Exploring Federal and State Incentives

Finally, the board researched available government incentives. They investigated potential tax benefits or grants for installing energy-efficient technologies, which helped shape the financial model for the project.

Financial Modeling for EV Charging

With a clear understanding of the technical and regulatory requirements, the board developed a comprehensive financial model. This step was crucial for ensuring the project’s long-term sustainability and securing resident buy-in.

Estimating Hardware and Installation Costs

The financial committee began by gathering quotes for all physical components. They evaluated technologically advanced solutions from various providers, including TPSON, to understand the range of available features and price points. The total capital expenditure (CAPEX) was broken down into clear categories.

This detailed breakdown helped the board understand that installation labor, not just the hardware, represented a significant portion of the initial investment.

Projecting Software and Network Fees

The board chose smart chargers, which required ongoing software subscriptions. These recurring operational expenditures (OPEX) were essential for managing the EV charging network effectively. The projected monthly fees covered several critical functions:

• User authentication and access control
• Automated billing and payment processing
• Load management to prevent overloading the building’s grid
• Surveillance et diagnostic à distance

Ces frais logiciels ont été intégrés au modèle de récupération des coûts pour garantir l'autofinancement du système sur le long terme.

Comparaison des modes de financement : Fonds du condominium vs. Contribution spéciale

Le conseil a présenté aux résidents deux options de financement principales pour l'investissement initial en infrastructure. Chaque option présentait des avantages et des inconvénients distincts.

Considération clé : Le conseil a recommandé une approche hybride. Il a proposé d'utiliser une partie du fonds de réserve du condominium pour démontrer son engagement, puis de lever une contribution spéciale modérée pour couvrir le solde restant. Ce modèle de responsabilité partagée s'est avéré plus acceptable pour les résidents.

La première option consistait à utiliser le fonds de réserve général (fonds de réserve). La deuxième option était une contribution spéciale (contribution spéciale) facturée à toutes les unités. Après de nombreux débats en assemblée générale, les résidents ont approuvé le modèle hybride. Évaluation des modèles d'opérateur tiers.

Dans le cadre de leur diligence raisonnable, le comité a également évalué un modèle d'opérateur tiers. Dans ce scénario, une entreprise externe installerait et exploiterait les bornes avec peu ou pas de coût initial pour le condominium. L'opérateur percevrait ensuite tous les revenus, en rétrocédant un faible pourcentage à la copropriété. Bien que ce modèle élimine l'investissement initial, le conseil l'a rejeté. Il souhaitait un contrôle total sur la tarification, l'expérience utilisateur et la capacité de réinvestir directement les revenus dans la maintenance et l'expansion future.

Phase 2 : Programme pilote et modernisation de l'infrastructure.

Une fois la planification terminée, le condominium est passé à la phase d'exécution. Cette phase s'est concentrée sur le lancement d'un programme pilote contrôlé pour tester le système en conditions réelles, tout en modernisant l'infrastructure électrique principale de l'immeuble pour une évolutivité future.

Mise en œuvre du programme pilote.

Sélection des emplacements du programme pilote

Le conseil a utilisé une approche basée sur les données

(approche axée sur les données) pour sélectionner les emplacements des premières bornes. Il a analysé les données de l'enquête auprès des résidents et les plans de l'immeuble pour identifier quatre emplacements stratégiques dans une zone commune très visible du garage. Ces emplacements ont été choisis car ils étaient proches du tableau électrique principal, ce qui a minimisé les coûts de câblage initiaux, et étaient facilement accessibles au premier groupe de propriétaires de véhicules électriques. Installation du premier jeu de bornes.

Un entrepreneur électricien certifié a installé quatre bornes de recharge intelligentes AC de niveau 2. L'installation a impliqué de tirer de nouvelles conduites depuis un sous-tableau jusqu'aux places de parking désignées et de fixer solidement les bornes. Les travaux ont été réalisés sur un week-end pour minimiser les perturbations pour les résidents.

Test de l'interface utilisateur et du système de paiement.

Avant la mise en service, le gestionnaire immobilier et quelques membres du conseil ont testé l'ensemble du parcours utilisateur. Ils ont téléchargé l'application mobile, créé des comptes, initié des sessions de recharge et effectué des paiements tests. Cette étape cruciale a permis d'identifier et de corriger des bogues logiciels mineurs, garantissant une expérience fluide pour les résidents dès le premier jour.

Collecte des premiers retours utilisateurs.

Le conseil a activement collecté les retours des utilisateurs pilotes. Il a suivi des

indicateurs clés de performance pour mesurer le succès et identifier les axes d'amélioration. Temps de disponibilité du système.

Modernisation de l'infrastructure électrique principale de l'immeuble

Dimensionnement et modernisation du tableau principal

Un ingénieur électricien a déterminé que le tableau électrique principal nécessitait une modernisation pour soutenir la vision complète et à long terme de la recharge pour véhicules électriques. Le conseil a approuvé le projet d'installation d'un nouveau tableau de distribution principal de plus grande capacité, créant une base solide pour l'expansion future.

Installation de conduites et câblages dédiés

Pour se préparer à la demande future, le condominium a installé des “goulottes” ou conduites vides courant vers différentes sections du garage. Bien que plus coûteuse initialement, cette stratégie de pré-câblage a considérablement réduit le coût et la complexité de l'ajout ultérieur de nouvelles bornes.

Mise en œuvre de systèmes de gestion de charge

Le conseil a mis en œuvre un système de Gestion Dynamique de la Charge (GDC) pour éviter les surcharges électriques. Cette technologie intelligente agit comme un conducteur intelligent pour l'alimentation électrique de l'immeuble.

Un système GDC surveille en permanence la consommation électrique totale de l'immeuble. Il ajuste automatiquement et en temps réel la puissance envoyée à chaque borne de recharge pour VE. Si la consommation de l'immeuble augmente brusquement, le GDC réduit les vitesses de recharge pour maintenir la charge totale dans des limites sûres, évitant ainsi le déclenchement des disjoncteurs.

Conformité aux normes NBR 5410

Tous les travaux électriques ont strictement respecté la norme brésilienne NBR 5410 pour les installations électriques basse tension. Le conseil a engagé un ingénieur diplômé pour inspecter et certifier l'installation finale, garantissant ainsi la sécurité et la conformité de l'ensemble du système.

Choix de la technologie appropriée

Bornes AC de niveau 2 vs. Bornes DC rapides

Le conseil a évalué à la fois les bornes AC de niveau 2 et les bornes DC rapides. Pour un cadre résidentiel où les voitures stationnent toute la nuit, le choix était clair.

Les bornes AC de niveau 2 offraient le compromis idéal entre coût et identique en prix. vitesse pour les besoins du condominium.

Bornes intelligentes vs. Bornes “simples”

Le comité a choisi des bornes “intelligentes” plutôt que des bornes “simples” de base. Les bornes intelligentes se connectent à Internet, permettant des fonctionnalités essentielles comme la surveillance à distance, le contrôle d'accès et la facturation automatisée, qui étaient critiques pour gérer une ressource partagée dans un grand immeuble.

Managing Waitlists and Prioritization

Demand for new chargers quickly outpaced the installation schedule. The board created a transparent digital waitlist. Priority was given based on the date of request. This first-come, first-served system was communicated clearly to all residents, managing expectations and preventing disputes.

Integrating New Chargers into the Network

Each new charger, whether in a common area or a private spot, was integrated into the central management software. This ensured every station, including technologically advanced units from providers like TPSON, operated under the same rules, billing system, and load management protocol.

Resident Communication and Onboarding

Developing a Communication Plan

Clear communication was paramount. The board understood that providing too much information was better than providing too little.

The communication plan outlined how the board would engage residents at every step. This proactive approach prevented information gaps and ensured residents felt included in the process. Consultation helped the board understand specific concerns and requirements.

Conducting Resident Training Workshops

The property manager hosted several training workshops. These sessions demonstrated how to use the mobile app, start a charging session, and understand the billing process. This hands-on training built resident confidence in the new EV charging system.

Creating a Digital Sign-Up Process

A simple digital sign-up form was created on the condominium’s resident portal. New users could register their vehicle, link a payment method, and gain access to the charging network within minutes.

Publishing Usage Rules and Etiquette

The board published a clear set of rules and etiquette guidelines. These rules covered topics like session time limits during peak hours, proper cable management, and the importance of moving a vehicle once charging is complete.

Billing and Cost Recovery in Action

Setting the Price per kWh

The board set the price per kilowatt-hour (kWh) slightly above the utility’s commercial rate. This small margin was designed to cover electricity costs, software fees, and future maintenance, making the system financially self-sufficient.

Implementing Idle Fees and Session Charges

To maximize charger availability, the board implemented an idle fee policy. This practice discourages drivers from leaving their cars parked in a spot after charging is complete. A small per-minute fee would begin 15 minutes after a session ended, ensuring the chargers were available for the next user.

Managing Revenue for O&M Costs

All revenue from charging sessions and idle fees was directed into a dedicated fund. This fund was used exclusively for operations and maintenance (O&M), including software subscriptions, network fees, and any necessary hardware repairs.

Monthly Reporting to Residents and Board

The board provided transparent monthly reports. These reports detailed total energy consumption, revenue collected, and operational costs. This transparency maintained resident trust and demonstrated the project’s financial health.
