A battery charger controller manages the charging process for the selected battery system.

## In plain English

### What does Battery charger controller mean?

A battery charger controller manages the charging process for the selected battery system.

### A simple example

A charger can regulate its output according to the battery's charging requirements.

### What the drawings help you do

Draw the controller beside the power-conversion stage it commands. The controller decides how charging should progress; the power stage moves the energy. Identify the battery-feedback signals separately so a reader can distinguish charging power from the measurements used to control it.

### Before using this reference

- Identify the battery type and charging requirements.
- Separate power-stage connections from feedback signals.
- Show the charge-enable and charge-status interfaces.

### Is this the complete battery charger?

A controller may require external switches, magnetics, measurement circuits and protection. Use the selected charger design to establish what is integrated and what must be supplied separately.

### Terms

- Power stage: The circuit that actually converts and transfers charging power.
- Feedback: A measurement returned to a controller so it can adjust its action.

## How to read it

- Identify the battery type and charging requirements.
- Separate power-stage connections from feedback signals.
- Show the charge-enable and charge-status interfaces.
- A charger controller is not the battery cells or necessarily the complete power converter.

## Information to show or reference
