Real-World Field Validation & Endurance Testing

Public Transport OEM · Field Endurance Programs &
real-world performance validation

Tens of thousands of test kilometers across diverse real-world routes reveal only vehicle-level energy consumption, without visibility into subsystem behavior (propulsion, HVAC, auxiliaries, doors, compressors)
Identical buses show 5- 20% energy variance under real-world conditions - far beyond controlled UITP E-SORT testing - with no clear understanding of root causes
Gap between certification results (half-load, controlled conditions) and field performance (variable passenger loads, extreme weather, aggressive duty cycles) can reach 40–50%
Unlike controlled certification testing, field conditions include extreme temperatures affecting HVAC consumption, variable passenger loads (0-80+ passengers = 6-ton difference), 40-60 stops/hour in urban duty cycles, diverse driver behaviors, and aging effects over time
Root-cause analysis depends on guesswork and repeated test loops, generating massive data volume without actionable subsystem-level insight

Non-intrusive, high-resolution energy trace for every kilometer of field and endurance testing across urban, suburban, and intercity routes - capturing real-world variability that controlled certification cannot replicate
Fingerprinting of HV and LV subsystem behavior across diverse routes, variable passenger loads (empty to full), temperature extremes, stop-and-go patterns, and driver behaviors
Continuous detection of energy drift versus baseline patterns with automatic anomaly flagging - identifying deviations caused by real-world conditions vs design expectations
Bridges the gap between UITP E-SORT certification performance and actual field operation, enabling validation that tender commitments hold under real operator conditions

Transforms tens of thousands of mileage kilometers into high-resolution energy validation with subsystem-level insight - moving beyond simple range tracking
Identifies root causes of 5-20% variance between identical buses early in the validation cycle, before production launch or operator complaints
Enables robust energy-stability benchmarking across bus models, configurations, and route profiles under real-world conditions
Validates that certification commitments (UITP E-SORT) translate to field performance, protecting against 40-50% gaps that can trigger warranty claims or operator dissatisfaction
Accelerates SOP readiness and minimizes post-launch surprises in real operator usage, diverse climates, and high-utilization duty cycles
