Electricity meter — Energy Measurement Function (EMF) — EN 50463
The ECM-4000 is an on-board electricity meter for electric traction vehicles, implementing the Energy Measurement Function (EMF) defined by the EN 50463 series of standards. It measures voltage and current on the traction power supply and calculates the electrical energy consumed and regenerated by the vehicle.
Measured energy values are stored in load profiles and made available to a Data Handling System for compilation into billing data. The ECM-4000 is the metering building block of the ECMS-4000 electricity measurement system.
The ECM-4000 is designed in accordance with the EN 50463 series (railway applications — energy measurement on board trains), in particular EN 50463-1 (general), EN 50463-2 (energy measuring) and EN 50463-3 (data handling interface).
