What is the Difference Between a BMS and a Balancer?
When utilizing lithium batteries in any application, the terms 'Battery Management System' (BMS) and 'balancer' often surface. Though they are both critical for battery health and efficiency, they fulfill different roles within the battery's ecosystem. Understanding these differences is essential for anyone engaged in the DIY off-grid energy space.
The Role of a Battery Management System (BMS)
A BMS is an electronic system incorporated within lithium battery packs. It's responsible for protecting lithium cells against a multitude of risks that can reduce the battery's lifespan or lead to unsafe conditions. These risks include overcharging, deep discharging, operating under high or low temperatures, and handling excessive current. If any of these parameters are exceeded, the BMS intervenes by disconnecting the flow of current to or from the battery bank, effectively mitigating potential damage.
The Function of a Balancer
On the other hand, a balancer is designed to ensure uniformity among the cells in a battery pack. Over time, individual cells within a lithium battery can develop variations in charge levels, which can affect performance and longevity. A balancer corrects these imbalances by evening out the state of charge across all cells.
Types of Balancers: Passive vs. Active
Balancers are categorized into passive and active systems:
Passive Balancers: These systems level the charge by dissipating the excess energy from more charged cells as heat. This process is simpler and less costly but is not energy-efficient since the excess charge is not reused but lost.
Active Balancers: In contrast, active balancers redistribute energy from cells with a higher charge to those with a lower charge. This method not only maintains balance but also conserves energy within the battery system, enhancing overall efficiency.
Both a BMS and a balancer are integral to the health and functionality of lithium battery packs. A BMS protects against unsafe operating conditions, while a balancer ensures all cells work cohesively, maintaining balance and extending the battery's service life. For individuals invested in creating sustainable energy solutions, comprehending the distinct functions of these systems is invaluable.

What is an Active Balancer Module?
An Active Balancer Module (Active Balancer) is a unit which will “Actively” balance the voltage between 2 or more cells connected in series. When charging/discharging cells connected in series, each cell will behave differently depending on their internal resistance which will result in the being unbalanced. The more you charge/discharge the battery bank, the State of Charge (SOC) and voltage variance between the cells will increase, resulting in 1 cell having a greater SOC, while another cell within the same bank having a lower SOC. The problem with this is the potential for the cell with the higher SOC being overcharged, while the cell with the lower SOC being over discharged and therefore those cells experiencing a greater derogation in comparison to the other cells.
An Active Balancer will monitor and transfer current between cells within a bank. Cells with a higher SOC, to cells with a lower SOC ensuring they are better balanced and drastically reducing the chance of one particular cell in the bank being over charged/discharged.
Unlike a passive balancer, an active balancer will operate while a battery bank is being charged, discharged or even left in storage.
What is a Passive Balancer?Most BMS’s will have a built-in balancing function, however for the majority of BMS’s currently available this will be a Passive Balancer. A Passive Balancer will attempt to balance cells within a bank by increasing the resistance to cells with a higher voltage/State of Charge (SOC), allowing for more current to flow to cells with a lower voltage/SOC. A Passive Balancer only works while the bank is being charged, which means cells within a bank can still fall out of balance while being discharged.
What is a BMS Parallel Module?
The main purpose of a BMS Parallel Module is to regulate the current flow between 2 or more banks of batteries connected in parallel.
When 2 or more banks of batteries are connected in parallel, the State of Charge (SOC) of the different banks will equalise. That means, they will transfer current from the highest charged bank to the lowest charged bank until they have the same SOC, and therefore have the same voltage. With LiFePO4 Cells, this transfer of energy can be significant, and the high current flow will most likely be too great for BMS, while also causing damage the LiFePO4 cells.
The charge profile for LiFePO4 cells is relatively flat, that means there can be a large variance in the SOC between 2 or more cells, with a small variance in their comparative voltages. For example, you may have only 0.1V difference in voltage between 2 cells, however there will be a big variance in the SOC between these cells.
By using a parallel module, if 2 or more banks are connected in parallel, it will restrict the amount of current transferred between the banks, therefore protecting the BMS and the cells from any potential damage.
Some might say that if you have 2 more bank always connected in parallel then they will always be equalised… Although this might be true in principle, practically there are a couple of scenarios which may see 2 banks attempt to equalise, creating a situation of high current transfer, such as:
- Before initially connecting banks in parallel, you should need to top balance ALL cells which will ensure they have the same SOC otherwise they will equalise when connected in parallel.
- If you have 2 banks connected in parallel, 1 bank maybe disconnected by the BMS due to one of the protection parameters (like cell voltage variance) being triggered. If this happens, then one bank will continue to provide/receive current and therefore increasing the variance of the SOC between the banks. When you attempt to reconnect the bank into the parallel circuit, the banks will attempt to rebalance transferring unrestricted current.
How to connect Batteries in Series?
Connecting batteries in Series is when you connect the positive terminal of one battery to the negative terminal of another battery.
Connecting batteries in series will increase the combined Voltage of the packs but the capacity will remain unchanged (or lowest capacity of the combined cells). For example, if you have 4 x 3.2V (Volt) 200ah (amp hour) batteries connected in series, the total capacity will remain to be 200ah, however the voltage will increase to 12.8 Volts (4 x 3.2V).
When connecting cells/batteries in Series, the capacity of each battery should ideally be the same to ensure that one battery/cell in the circuit is not over charged/discharged.
