4. Monitoring components
like the Home Energy Management System
(HEMS) and Battery Management System
(BMS) track energy usage and battery
status real time, while cloud-connected
EVSE platforms enable remote supervision

Component/ Tool Operational Role
Instrumentation
Precision Power
Analyzers
Acquires high-fidelity voltage and current
waveforms sub-cycle resolution; supports
harmonic decomposition and transient analysis.1)
Monitors charging sessions and faults remotely
Diagnostics Harmonic Distortion
Analyzers
Quantifies THD and individual harmonic; supports
IEEE 519/EN 50160 compliance checks
Rate-of-Change Error
Detectors (RoC)
Identifies dynamic anomalies like mismatch, delay,
overshoot; enables early fault detection during
transitions
Event Loggers with
Time-Tagging (<1
ms)
Records fault events with high-resolution
timestamps; supports root-cause analysis and
synchronization with external system logs
.2s better)
Monitors power, voltage, frequency with high
accuracy; incorporates edge analytics for localized
insights
Phasor
Measurement Units
(μPMUs)
Provides time-synchronized phasor (V, data;
facilitates grid event correlation and real-time
disturbance diagnostics
Home Energy
Management Systems
Tracks home load-EV interaction; enables dynamic
scheduling and load disaggregation
Battery Management
System Telemetry
Continuously reports State Charge (SoC), State
of Health (SoH), cell temperatures, and voltage
balancing; supports prognostic health monitoring
