Smart energy consumption, cost savings, resilience, resource conservation, and environmental efficiency are just a few of the advantages provided by a battery energy storage system (BESS). BESSs range in size and power capacity from small household devices to large-scale systems used in utilities and industrial applications. In 2022, the number of battery-powered energy storage systems (BESS) installed in the United States will increase by 80%. Large-scale BESSs are now operational in countries such as the United States, Australia, the United Kingdom, Japan, China, and many others.
A BESS is an energy storage system (ESS) that collects energy from various sources, and stores it in rechargeable batteries for later use. If necessary, the electrochemical energy from the battery is discharged and supplied to homes, electric vehicles, and industrial and commercial facilities. A BESS is a hybrid system that combines hardware components with low- and high-level software. The primary BESS components are as follows:
Individual battery cells convert chemical energy into electrical energy. The cells are arranged in modules, which form battery packs.
A BMS ensures the battery system's safety. It monitors battery cell health, measures parameters and states such as state-of-charge (SOC) and state-of-health (SOH), and protects batteries from fires and other hazards.
This transforms the direct current (DC) generated by batteries into the alternating current (AC) supplied to facilities. Bidirectional inverters in battery energy storage systems enable charging and discharging.
This is in charge of monitoring and controlling the energy flow in a battery storage system. An EMS coordinates the activities of a BMS, a PCS, and other BESS components. An EMS can efficiently manage the system's power resources by collecting and analyzing energy data.
A BESS may also include a variety of safety systems, depending on its functionality and operating conditions, such as a fire control system, a smoke detector, a temperature control system, and cooling, heating, ventilation, and air conditioning systems. The safety systems have their own monitoring and control units that provide the conditions required for a BESS's safe operation by monitoring its parameters and responding to emergencies.
Complex BESSs rely on robust software solutions in addition to electronics. Modern systems, for example, use machine learning algorithms to optimize energy management. Estimating battery states and characteristics with high accuracy necessitates the use of dependable algorithms and mathematical models developed as part of the BMS software development process.
In summary, a BESS collects energy from the power grid or renewable energy sources such as solar and wind and stores it using battery storage technology. The energy is then discharged and released when needed—during peak demand, power outages, and a variety of other applications.
BESSs can accommodate a variety of batteries, including lithium-ion, lead-acid, nickel-cadmium, and others—we'll go over them in more detail later in the article. Each battery type has unique technical specifications that define BESS applications and impact battery energy storage efficiency. The primary battery characteristics are as follows:
Storage capability. This is the amount of electric charge that a battery can store or the amount of electricity that a BESS can provide.
Power. This parameter specifies the amount of power supplied by a battery or the output power of a BESS.
Round-trip effectiveness. The ratio of energy delivered by a battery during discharge to energy supplied to the battery during a charge cycle is shown here.
DoD stands for Depth of Discharge. This graph depicts the percentage of energy discharged from a battery in comparison to its total capacity.
Lifetime. This is the number of charge and discharge cycles or the amount of energy that a battery can supply over its lifetime (battery throughput).
Safety. This is an important feature that indicates the battery's compliance with safety requirements, such as battery chemistry.
Storage battery systems have additional characteristics that describe their performance in addition to the battery specifications listed above. For example, response time is the amount of time it takes a BESS to transition from idle to full power. The ramp rate is the rate at which the system can increase or decrease its power output—that is, ramp it up or down.
Tailor-made BESSs can compensate for shortcomings in off-the-shelf solutions provided by major battery storage system providers. As a result, they can precisely meet the needs of your potential customers. Implementing a custom product, on the other hand, is a time-consuming and resource-intensive task. Building a battery energy storage solution is a large-scale, long-term project that can take months or even years to complete.
Because a BESS is a complex, multilayer engineering system, creating a battery-based storage solution from the ground up necessitates extensive knowledge in a variety of fields, including battery technologies, power electronics, and embedded software development.

Choosing the right development team is half the battle; that is why hiring well-trained professionals with relevant experience is critical. To build a battery energy storage system from the ground up, experts in electronic design, electrical engineering, low-level firmware, high-level software, and mechanical engineering are required.
The Integra Sources team may be a good match for your project. We create PCBs for BESS's battery management, bi-directional power conversion, energy management, and safety systems. For remote BESS management, our engineers implement monitoring and control software and provide online data communication. We develop scalable battery energy storage solutions that have a quick response time, a quick ramp rate, and a high-efficiency power supply. Our BESSs, when integrated with either electrical grids or renewables, can perform load management, power backup, frequency and voltage regulation, energy time-shifting, and a variety of other functions.
Another significant challenge you'll face when developing your battery energy storage product is manufacturing. The BESS manufacturing process includes a variety of tasks that can be completed at various production facilities. As a result, synergy is essential for efficient BESS manufacturing.
You'll also need to handle product certification. Aside from international standards like IEC, ISO, IEEE, and UL, a BESS will almost certainly need to meet specific national standards and certification requirements in each country. In the United States, for example, an energy storage system must also comply with the regulations of the Federal Energy Regulatory Commission (FERC), the Department of Energy (DOE), and some state regulatory agencies.
AS/NZS 5139:2019, developed by Australia and New Zealand in October 2019, is a joint standard that specifies general installation and safety requirements for battery energy storage systems. Furthermore, Australian BESS manufacturers must adhere to a number of other national and international codes and standards.
The industry and application area of a BESS may also influence certification criteria. DNV, for example, offers a recommended practice that includes guidelines for energy storage design, performance, operation, maintenance, and safety in marine systems. The specification includes charge/discharge rate, SOC, SOH, DoD, and many other system parameters and operating conditions.
The BESS development engineering team must be well-versed in the certification requirements and applicable standards. This reduces risks in the system's design and ensures that a high-quality product is delivered to your end user on time and within budget.
Despite the challenges, designing a custom BESS can improve usability, lower operating costs, and increase system reliability. After researching the market, you can take into account the needs of your customers, as well as the shortcomings of off-the-shelf BESSs, to develop highly sought-after battery energy storage solutions.
When you implement your product, you become independent of any specific BESS provider and its services. You can set up, maintain, support, and deliver other services to your customers quickly and without the use of intermediaries.
