Detecting Subsystem Degradation
Over the Vehicle Lifecycle
EV OEM · Fleet quality programs and long-term durability monitoring
Challenge
-
As EVs accumulate mileage, subsystems degrade at different rates, but degradation remains invisible until it causes functional failure.
-
2–10% higher energy consumption appears long before systems fail, with no way to detect which subsystem is the culprit.
-
Root-cause analysis is slow, expensive and often inconclusive, leading to costly recalls or field campaigns.
V-Hola Solution
-
Continuous subsystem energy trace across the entire vehicle lifecycle in both OEM fleets and customer operations.
-
Detection of gradual increases in energy load for specific components versus their original baseline performance.
-
Early-stage degradation flagging before customers or fleets experience range loss or no-start events.
Impact
-
Ongoing verification of energy impact over time and distance, enabling predictive warranty and quality strategies.
-
Early detection minimizes cascading failures and prevents costly field campaigns or recalls.
-
Enables design improvements in future programs by identifying subsystems with accelerated degradation patterns.
-
Builds a continuous quality baseline from production through the vehicle's operational life.
Customer Profile
-
Global EV OEM with active quality and durability programs across fleet cohorts.
-
Focus on long-term vehicle health monitoring and predictive warranty management.
-
Need for early detection of performance drift to minimize customer impact and operational cost.
