Kazam partners with 15+ CPOs and roaming networks, giving users access to multiple chargers with one login and wallet, ensuring seamless flexibility and interoperability.
Discover, connect, and roam across networks
A single interoperability layer for chargers, networks, and mobility platforms using open standards.
What Interoperability Means in EV
Understanding the difference between fragmented systems and connected infrastructure
Without Interoperability
With Interoperability
✕
Locked Networks: Drivers restricted to single network charging apps
✓
Seamless Roaming: Drivers access any charger through their preferred app
✕
Poor Driver Experience: Multiple apps, accounts, and payment methods required
✓
Unified Discovery: Real time charger availability across all networks
✕
Manual Roaming Agreements: Time consuming bilateral negotiations and integrations
✓
Cross Network Billing: Automated settlement and transaction reconciliation
✕
Fragmented Data: Inconsistent reporting and operational visibility
✓
Shared Operational Visibility: Consistent data formats and reporting standards

Energy-Based vs. Time-Based EV Charging Billing
Most EV charging station billing systems price sessions in one of two ways:
- Energy-based (per kWh): Drivers pay for the electricity actually consumed — the fairer, increasingly standard model.
- Time-based (per hour/minute): Drivers pay for how long they occupy the charger, regardless of charging speed.
Kazam's Tariff Engine supports both models, plus Time-of-Day, Flat, and Fast-Charging tariffs, so operators can price exactly how their business needs to.
