Charging energy measurement records the electrical energy passing through the defined measuring point.

## In plain English

### What does EV charging energy measurement mean?

Charging energy measurement records the electrical energy passing through the defined measuring point.

### A simple example

A station can use the measurement to report energy delivered during a charging session.

### What the drawings help you do

Locate the measuring point on the power path and label whether it is on the AC input or DC output side. Energy adds up over time, whereas power is a rate at a particular moment. The location matters because losses between two points can make their recorded energy differ.

### Before using this reference

- Identify the metering point and measured circuit.
- Distinguish energy readings from instantaneous power.
- Reference the selected meter’s measurement and reporting requirements.

### Why can station-input energy differ from vehicle-delivered energy?

Conversion equipment and auxiliaries can consume energy between the two measuring points. Compare readings only after identifying their locations, time periods and the quantities each meter records.

### Terms

- Energy: Electrical transfer accumulated over time, often reported in kilowatt-hours.
- Power: The rate of electrical energy transfer.
