Pack-current measurement reports current entering or leaving the battery.

## In plain English

### What does Battery pack current measurement mean?

Pack-current measurement reports current entering or leaving the battery.

### A simple example

A battery controller can use current direction and magnitude when managing charge and discharge.

### What the drawings help you do

Mark the exact conductor or shunt where current is measured and define the positive direction. Charging and discharging can produce opposite signs. The measurement can support a battery estimate, but a current-reading block alone does not contain the history or battery model needed for that estimate.

### Before using this reference

- Identify the sensing method and measurement location.
- Define positive current as charging or discharging.
- Show the measurement output and reference domain.

### Does a current reading show battery capacity?

An instantaneous current value shows electrical flow at that moment. Estimating remaining charge also requires a method that accounts for time and the battery’s behaviour, together with the measurements it uses.

### Terms

- Shunt: A known low resistance used to obtain a current-related voltage.
- Current direction: The convention that determines the sign of a reported current.

## How to read it

- Identify the sensing method and measurement location.
- Define positive current as charging or discharging.
- Show the measurement output and reference domain.
- A current measurement alone does not establish cell state of charge or battery health.

## Information to show or reference

- Identify the sensing method and measurement location.
- Define positive current as charging or discharging.
- Show the measurement output and reference domain.

## Important distinction

A current measurement alone does not establish cell state of charge or battery health.
