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

A distinction that matters
Passive balancing dissipates energy; it does not transfer that energy to another cell.
