Some cells hold energy better than others. This can make some cells work harder. Over time, this hurts battery performance and makes it not last as long.

Battery equalization keeps every cell at a similar charge level. Your battery gets better capacity and lasts longer. You avoid problems like overheating or failing early. Here are some important things about battery equalization:

  • You balance energy between cells to stop power problems.

  • You use active or passive ways to keep cells healthy.

  • You protect your battery from damage when charging or using it.

  • You make lithium battery systems work better, especially in series packs.

Tip: Battery equalization helps your lithium battery last longer and stay safe.

How It Works

Battery equalization uses different ways to keep cells balanced. There are two main types: active and passive equalization. Active balancing moves energy from cells with more charge to cells with less charge. Passive balancing uses resistors to burn off extra energy from cells with more charge. Both ways help your lithium battery work well.

You can see how these ways compare in the table below:

Method

Description

MC2MC Active Equalization

Equalization Circuits and Techniques

There are different circuits and ways to balance lithium battery cells. Some advanced methods use bi-directional converters. These circuits move charge between cells using special switches. This helps balance many cells quickly and well.

Charge shuttling is another way. It uses outside capacitors to move energy between cells. This method can be very efficient, almost 99%. Capacitor topologies, like SC, SSC, DTSC, and CNSC, work in three steps: charging, discharging, and dead time. These steps help control how energy moves between cells.

Here is a table that shows how these methods work:

Method Type

Functionality

Bi-directional Converter

Why Equalization Matters

Common Battery Issues Solved

Sometimes, your battery does not work as well as you want. This can happen because the cells inside are different. These differences come from how the battery was made, how old it is, or how heat moves inside. Here are some problems that battery equalization can fix:

  • Cells may not match because of small changes in how they were made or how they age.

  • Some cells can get sulfate crystals, which makes them hold less energy.

  • If one cell is weak, you cannot use all the battery's power safely.

  • Acid can settle in the wrong places, which can make the battery work badly and be unsafe.

An equalizing charge helps all the cells reach the same charge. It also gets rid of sulfate crystals and fixes acid problems. This keeps your battery strong and ready to use.
