Problem
Electric vehicle owners and property managers often face charging solutions that require constant internet connectivity, complex installation, and separate payment apps, limiting accessibility and efficient billing for residential, condominium, and commercial sites.
Solution
Ambar‑e delivers an integrated hardware‑software platform that provides intelligent EV charging across homes, condominiums, and businesses. The chargers operate offline via Bluetooth and can be upgraded to OCPP for networked load balancing, ensuring reliable operation even in garages without Wi‑Fi. Users identify themselves with NFC tags or through WhatsApp/Telegram, removing the need for dedicated mobile applications. A cloud‑based management suite generates individual consumption reports, automates invoicing via PIX or card, and offers an administrative dashboard for revenue and utilization monitoring. The product line includes plug‑and‑play AC units up to 7.4 kW for residential use and fast DC units up to 60 kW for commercial demand, and it is compatible with third‑party OCPP chargers. Installation is performed by certified partners, complying with national safety standards, and customers can lease chargers with all services bundled for a fixed monthly fee.

Primary customers are residential EV owners, condominium administrators, and commercial operators of parking facilities or fleet charging stations who need reliable, low‑maintenance charging infrastructure.
