Active battery cell balancer
In plain English
What does Active battery cell balancer mean?
An active balancer transfers energy between selected parts of a battery system.
A simple example
A converter-based balancing path can move energy rather than only dissipating it in a resistor.
What the drawings help you do
Identify the cell or pack sections between which energy can move, together with the balancing controller. The distinguishing feature is an energy-transfer circuit, not just a measurement of unequal cell voltages. Draw its power-transfer path separately from the information used to decide when to balance.
- Energy transfer
- Moving energy through a controlled electrical path.
- Balancing controller
- The function that decides which battery sections should be balanced.
Before using this reference
- Identify the source and destination of transferred energy.
- Show the selected converter or switching arrangement.
- Reference the controller’s cell-selection and operating conditions.
Is active balancing lossless?
No. The transfer circuit has losses and design limits. Its distinction from passive balancing is that it redirects some energy instead of deliberately dissipating all removed balancing energy in a bleed path.

A distinction that matters
The energy-transfer path and control method depend on the selected balancing design.
