Fast Root-Cause Identification for
No-Start Events

Challenge
-
When a bus fails to start in the morning or after depot parking - service is already at risk
-
The root cause is unclear: battery, BMS, HVAC, doors, telematics, or auxiliary systems may all be suspected
-
Maintenance teams have no clear visibility into electrical behaviour before the failure
-
Diagnosis depends on manual checks, experience, and part swapping - slow and uncertain
-
Each immobilized bus triggers cascading issues: delayed pull-out, spare vehicle usage, technician overload, and operational pressure
Impact
-
Faster diagnosis and quicker return of buses to service
-
Reduced depot congestion and technician workload during peak hours
-
Lower towing, spare vehicle, and emergency maintenance costs
-
Improved morning pull-out success and on-time service performance
-
Higher confidence in maintenance decisions, backed by data
V-Hola Solution
-
Non-intrusive energy fingerprinting captures subsystem behaviour during sleep and wake cycles around the no-start event
-
Rapid identification of which subsystem caused abnormal current draw or prevented startup
-
Precise fault isolation down to the responsible component - no guesswork
-
Root-cause diagnosis in hours instead of days
-
Objective, time-stamped data to justify repairs and escalate issues to OEMs or suppliers
