1. UFRJ Station – Fully Operational

Placement: Inside the Federal University of Rio de Janeiro (UFRJ) - one of Brazil’s top public universities, with over 50,000 students.

Status: Fully operational since September 8th

Insight: Strategically located in a hub of research, education, and institutional activity. High daily vehicle turnover from university staff, students, and service providers.

2. Dutra Station – High-Density Residential Zone

Placement: Located along the Via Dutra corridor, a key intercity route connecting Rio and São Paulo. This station is positioned in one of Rio’s most populous neighbourhood with 1 million inhabitants.

Status: Installation complete; awaiting transformer delivery

Insight: High vehicle flows and nearby commercial activity. Situated in gas station, with strong potential for recurring usage from local residents and daily commuters.

Technical note: The transformer requirement arises from the use of fast chargers, imported from China, which operate at a different voltage standard than Brazil’s grid. This ensures smooth integration.

3. Campo Grande Station – Av. Cesário de Melo, Paciência

Placement: Situated along Av. Cesário de Melo – one of the most trafficked roads in Rio’s West Zone, connecting major residential and commercial zones like Campo Grande and Santa Cruz.

Status: Installation complete; awaiting transformer connection

Insight: Situated in gas station, with within a growing urban corridor.

Technical note: As with Dutra, transformer installation is required to adapt the imported chargers to local voltage. This is a one-time technical alignment step that ensures compatibility with the Brazilian grid.

4. South Zone Station – Premium Tourist & Residential District

Placement: Located in affluent neighbourhood, near the iconic Christ the Redeemer, one of the most visited tourist destinations in the world.

Status:

• All infrastructure in stock
• Awaiting operational license for parking facility, to begin installation
• Also requires upgrade to electrical supply (installation of higher-capacity cables)

Timeline: Targeting operational license resolution within 30 days – site expected live in 1.5 to 2 months.

Insight: This area has one of the highest concentrations of EV ownership in Rio and virtually no charging infrastructure. Excellent positioning to capture premium vehicle traffic and tourism-linked usage. Situated in one of the only car parks available.

Yield Repayment Timeline

• Investor distributions remain on schedule. Yield payments are set to go out week commencing October 5th, with VOX EPOWER committing to a 3% capital repayment even ahead of full network activation. After fees, investors will receive a payment equal to 31.5% annualized yield.
• This proactive step, agreed in partnership with ReFi Hub, reflects a joint commitment to investor confidence and transparent execution.
• Final licensing and grid enhancements are underway to bring the remaining stations online in sequence.

Further updates will follow as new stations go live and performance data becomes available.
