The key design considerations for commercial and industrial (C&I) modular battery storage systems
What are the key design considerations for commercial and industrial (C&I) modular battery storage systems?
C&I energy storage uses batteries to store electricity for businesses. It offers tailored solutions to meet their unique energy needs and patterns. C&I energy storage systems typically use high-capacity, rechargeable batteries, such as lithium-ion batteries. These batteries can store energy generated during low-demand periods, such as overnight or during low-production periods, which can then be used during periods of high demand, saving businesses money on energy costs. C&I energy storage also improves the resilience of the power grid by providing backup power during outages or interruptions. In an era where business operations rely on a consistent power supply, having an efficient C&I energy storage system is a necessity.
What is the importance of Battery Energy Storage in the Industrial and Commercial Areas
In today's fast-paced industrial and commercial landscape, battery energy storage systems (BESS) have become an indispensable tool. At the core of this transition is the world's urgent need to enhance energy reliability, improve efficiency, and reduce carbon emissions.
As an energy storage manufacturer, we understand that businesses constantly strive to improve their operations and bottom line. In this regard, C&I energy storage plays a pivotal role. It enables businesses to store excess energy produced during off-peak hours for use during peak demand, helping them manage energy consumption more efficiently and save on electricity costs.
Notably, the potential of large-scale battery storage should not be understated either. It offers a promising solution to the intermittent nature of renewable energy sources like wind and solar power, making it possible to store large amounts of energy and deploy it when needed.
Benefits and Applications of Commercial (C&I) Energy Storage
C&I energy storage is rapidly gaining popularity due to the myriad of benefits it provides to industrial and commercial sectors. Below, we delve into a few key benefits and applications.
Reducing Peak Demand Charges
Peak demand charges form a significant part of electricity bills for businesses. These charges are levied during periods of highest energy usage, which typically occur during working hours. With C&I energy storage, businesses can store excess energy generated during non-peak hours and use it during peak hours, effectively reducing their peak demand charges and yielding considerable savings.
Providing Backup Power During Outages
Power outages can significantly disrupt business operations, leading to potential losses. C&I energy storage acts as a reliable backup power source during such instances, ensuring minimal disruption to operations and safeguarding businesses from the detrimental effects of power outages.
How are commercial and industrial (C&I) modular battery storage systems designed?
A commercial and industrial (C&I) modular battery storage system typically consists of the following components:
On inverter and PCS of commercial and industrial (C&I) modular battery storage systems:
The key design and parameters considerations for the inverter and power conversion system (PCS) of commercial and industrial (C&I) modular battery storage systems include safety, performance, reliability, and cost. In addition to these general considerations, there are a number of specific design and parameters considerations that must be made for C&I inverters and PCS, such as battery chemistry, system configuration, output voltage and current, efficiency, power factor, harmonic distortion, communication and control, scalability, and cybersecurity. Design considerations include topology, components, and cooling. Parameter considerations include voltage rating, current rating, power rating, efficiency, power factor, and harmonic distortion.
On battery modules of a commercial and industrial battery storage system:
The type of battery chemistry used in the modules will have a significant impact on their performance, durability, and cost. Common battery chemistries used in C&I applications include lithium-ion, lead-acid, and flow batteries. The battery modules can be configured in a variety of ways, depending on the specific requirements of the application. For example, the modules can be stacked vertically or horizontally, and they can be connected in series or parallel to achieve the desired voltage and current ratings.The battery modules must be properly cooled to ensure safe and reliable operation. This can be achieved using a variety of methods, such as air cooling, liquid cooling, and phase change materials.The battery modules must be able to communicate with the overall battery storage system controller. This allows the controller to monitor the performance of the modules and to take corrective action if necessary.
On battery management system(BMS) of a commercial and industrial battery storage system:
The BMS must be designed to ensure the safety of the battery system and to prevent damage to the batteries. This includes features such as cell balancing, overvoltage protection, overcurrent protection, and overtemperature protection. The BMS must also be able to accurately monitor and control the battery system to optimize its performance. This includes features such as state of charge (SOC) estimation, state of health (SOH) estimation, and power management. Additionally, the BMS must be highly reliable and able to withstand the harsh operating conditions of a C&I environment. This includes factors such as extreme temperatures, high humidity, and vibration. Finally, the BMS must be cost-effective in order to be a viable option for C&I battery storage systems.
The BMS must be able to communicate with other devices in the battery storage system, such as the inverter and the monitoring system. This allows the BMS to coordinate the operation of the system and to take corrective action if necessary.

Energy capacity: The energy capacity of a battery is the amount of energy that it can store. In this case, the battery has an energy capacity of 1MWh, which means that it can store 1 million watt-hours of energy. This is enough energy to power a typical American household for about 10 days.
Power capacity: The power capacity of a battery is the maximum amount of power that it can deliver. In this case, the battery has a power capacity of 250kW, which means that it can deliver 250,000 watts of power. This is enough power to power about 250 homes.
Battery chemistry: Lithium-ion batteries are the most common type of battery used in commercial and industrial battery storage systems. They are known for their high energy density, long cycle life, and low self-discharge rate.
Voltage: The voltage of a battery is the electrical potential difference between its positive and negative terminals. In this case, the battery has a voltage of 400V. This is a typical voltage for commercial and industrial battery storage systems.
Current: The current of a battery is the rate at which it delivers electrical charge. In this case, the battery can deliver a current of 625A. This is a high current, which means that the battery can deliver a lot of power in a short period of time.
Efficiency: The efficiency of a battery is the percentage of the energy that is stored in the battery that is delivered to the load. In this case, the battery has an efficiency of 95%, which means that 95% of the energy that is stored in the battery is delivered to the load. This is a high efficiency, which means that the battery is very efficient at delivering energy to the load.
Cycle life: The cycle life of a battery is the number of times that it can be charged and discharged before it reaches the end of its useful life. In this case, the battery has a cycle life of 5000 cycles. This is a long cycle life, which means that the battery can be used for many years before it needs to be replaced.
Operating temperature range: The operating temperature range of a battery is the range of temperatures at which it can safely operate. In this case, the battery can operate safely at temperatures between -20°C and 50°C. This is a wide operating temperature range, which means that the battery can be used in a variety of climates.
