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

A distinction that matters
A charger controller is not the battery cells or necessarily the complete power converter.
