What Is An Ess Battery And How Does It Work?

What Is An Ess Battery ?

An ESS (Energy Storage System) battery is a device that stores electrical energy for later use. It allows for efficient and effective management of energy from various sources, including renewable energy sources such as wind and solar power.

The basic components of an ESS battery include the battery cells, a battery management system (BMS), and an inverter. The battery cells are responsible for storing the electrical energy, while the BMS ensures the battery operates safely and efficiently. The inverter converts the DC (direct current) energy stored in the battery into AC (alternating current) energy, which can be used to power homes, businesses, and other electrical devices.

what's the advantage if we balance the battery cells ?

Cell balancing is a technique that improves battery life by maximizing the capacity of a battery pack with multiple cells in series, ensuring that all of its energy is available for use. A cell balancer or regulator is a functionality in a battery management system that performs cell balancing often found in lithium-ion battery packs electric vehicles and ESS applications.


Typically, individual cells of a battery pack have different capacities and are at different SOC levels. Without redistribution, discharging must stop when the cell with the lowest capacity is empty, even though the other cells are still not empty. This limits the energy delivering capability of the battery pack.

What you need to know before choose suitable ev battery ?

Choosing the right battery for an electric vehicle (EV) conversion is a particularly important step in the EV conversion process. If the battery pack does not match the drivetrain, the desired performance and range cannot be realized and there is also an additional risk of damaging the drivetrain components or the batteries themselves.

How to choose suitable battery for your application?

 How to choose suitable battery for your UAV, UAS, RC, or robotics application, LiPo (lithium polymer pouch cells) OR Li-ion (lithium-ion cylindrical cells) ? Firstly, we have to understand the pros and cons of both.

Pros of Lithium Polymer(pouch cells):

  • LiPo’s hold the highest voltage under load of all lithium batteries so they perform well in high amp draw applications

  • LiPo batteries come in many different form factors so they can be built to fit lots of applications

  • Maintains lower temperatures under high discharge

Cons of Lithium Polymer(pouch cells):

  • LiPo’s are more prone to thermal runaway when punctured or damaged

  • LiPo batteries provide around half the life cycles of a  Li-Ion

  • Can be discharged down to 3v per cell

Pros of Lithium ion(cylindrical cells):

  • Li-ion batteries are higher energy density(Wh/kg) which allows for longer runtimes and lighter weight

  • Lithium-ion batteries are safer than lithium polymer because of the metal enclosure

  • Can be discharged down to 2.5v per cell

Cons of Lithium ion(cylindrical cells):

  • In high amp draw applications, they will have lower voltage under load compared to lithium polymer

  • They are round cells in specific sizes which can create some limitations to fit in certain applications

  • They tend to hold higher temperatures during and especially after performing a higher discharge rate

We hope this gave you a better idea of what is better for your application.


We have make below tips for your easy understanding:


If you are looking for the highest voltage under load(punch or top speed) then choose a LiPo.


If you are looking for the highest capacity for the weight(energy density), choose Li-ion.


If safety is a big concern, then choose Li-ion.
