Future Truck Committee Position Paper 2018-3: Automatic Monitoring of Electrical System Health

TMC’s Future Truck Committee charged its Sensor Enhanced Maintenance Task Force to evaluate and state a position on the feasibility of automatic monitoring of electrical systemhealth. The finding of that task force is that automatic monitoring of electrical system health is achievable by combining onboard circuit analysis with Testing for Statistical Significance(TSS). When paired together, these two fundamentally sound sciences quantify the state of health (SOH) for batteries, alternators, starters, and electrical cables. The use of the SAE J1939 communication network allows for downloading of data, scheduling of maintenanceand integration with fleet management systems.
