About EZCharge
EZCharge is a unified EV charging platform designed to support national and cross-border charging networks. Built for a fast-evolving EV ecosystem in Brunei, the platform enables drivers to discover chargers, initiate sessions, track energy usage, and manage payments through a single mobile experience.
The system is engineered to support multi-operator networks, multiple charger types (AC & DC), and region-specific billing rules-making it ready for future expansion across Southeast Asia.
Key Goals
- Build a unified EV charging platform (iOS, Android, and web) designed to support multi-country charging networks.
- Enable users to discover stations, book chargers, start/stop sessions, and pay seamlessly from one super app.
- Empower operators with a centralized charging management system to handle tariffs, station health, and energy usage.
- Deliver a consistent cross-border user experience, regardless of the CPO or country-specific charging standards.
Challenges We Tackled
- Highly fragmented EV charging ecosystem with different CPOs, connectors, and billing rules.
- Roaming and interoperability issues between networks across multiple countries.
- Real-time sync challenges with station availability, energy consumption, and live session tracking.
- Need for a secure, multilingual, multi-currency payment flow compatible across regions.
Our Solution
XongoLab engineered a future-ready EV mobility ecosystem built to scale globally:
- A feature-rich EV super app enabling station discovery, reservations, QR-based charging, real-time session updates, and transaction history.
- Operator Dashboard with analytics on station usage, load distribution, peak times, pricing, commissions, and CPO performance.
- Smart routing with geo-fencing and advanced charger filtering (kW, connector type, availability), combined with energy-range predictions.
- Integrated multi-country roaming engine to standardize pricing, payments, and charging protocols.
- Automated engine for dynamic tariffs, idle fees, energy charts, and charging session logs.
