Test Every Edge Case. Break Before Production.

Simulated scenarios impossible to recreate with physical hardware

Smart Load Balancing

Simulate 100+ chargers sharing a 150kW grid connection. Watch dynamic power distribution prevent circuit overload.

Test Coverage:

  • Dynamic power allocation per charger
  • Priority-based charging queues
  • Real-time grid constraint responses
  • Time-of-use optimization

Metrics Validated:

Power distribution accuracy99.8%
Response latency42ms avg
Queue fairness100%
