A passive balancer removes some energy from selected cells through a dissipative path.

## In plain English

### What does Passive battery cell balancer mean?

A passive balancer removes some energy from selected cells through a dissipative path.

### A simple example

A balancing circuit can use a resistor to reduce the charge of a selected cell relative to others.

### What the drawings help you do

Draw the balancing branch beside the cell that it can discharge. Passive balancing deliberately turns some stored energy into heat to reduce a selected cell’s charge relative to others. A conceptual diagram should therefore show a dissipative branch, rather than arrows moving energy into a neighbouring cell.

### Before using this reference

- Identify the cells with balancing branches.
- Reference balancing control and thermal requirements.
- Keep balancing current separate from the pack load path.

### Where does the removed energy go?

It is dissipated, commonly in a resistive path. This differs from active balancing, which uses a conversion circuit to transfer energy between selected parts of the battery.

### Terms

- Bleed path: A controlled branch that removes charge from a cell.
- Dissipation: Conversion of electrical energy into heat.

Concept diagram: Selected higher-charge cell → Controlled bleed path → Energy dissipated as heat

## How to read it

- Identify the cells with balancing branches.
- Reference balancing control and thermal requirements.
- Keep balancing current separate from the pack load path.
- Passive balancing dissipates energy; it does not transfer that energy to another cell.
