How Battery Energy Storage Systems Help in Solar Energy Integration

As solar energy continues to grow as a sustainable alternative to fossil fuels, integrating it into our daily lives has become more efficient, especially with the help of Battery Energy Storage Systems (BESS). These systems play a crucial role in optimizing solar energy production by storing excess energy when the sun is shining and providing power during times of low sunlight or at night. In this micro blog, we will explore how battery energy storage systems complement solar power, ensuring a continuous and reliable energy supply.

What is a Battery Energy Storage System?

A Battery Energy Storage System (BESS) consists of batteries that store excess electricity produced by solar panels. When the sun is shining and solar power generation exceeds consumption, the surplus energy is stored in the batteries. When sunlight diminishes, such as at night or during cloudy days, the stored energy is used to power the home or business. This integration of solar power with battery storage ensures that the electricity supply remains consistent and dependable.

Key Roles of Battery Storage in Solar Energy Integration

Storing Excess Solar Energy for Later Use

Solar panels generate energy based on sunlight, but the power produced often exceeds immediate consumption, especially during peak sunlight hours. Without a battery storage system, this excess energy would be wasted, or in grid-tied systems, exported to the grid. With BESS, surplus energy is stored and can be used later when solar energy production is low or during periods of high energy demand, ensuring that you have power even when the sun isn’t shining.

Ensuring Energy Availability at Night and During Cloudy Days

One of the major limitations of solar power is its intermittent nature – it is only available when the sun is shining. A battery storage system bridges this gap by storing energy during the day and supplying power at night or on cloudy days. This capability is especially important in off-grid settings or areas with frequent power outages, providing a reliable and uninterrupted power supply.

Maximizing Self-Consumption and Reducing Energy Costs

For homeowners or businesses with solar panels, battery storage allows for greater self-consumption of solar energy, reducing reliance on the grid. Instead of exporting excess power to the grid (where compensation may be limited), you can store the energy for personal use, minimizing the need to purchase electricity from the utility company. This not only reduces your energy bills but also helps to optimize the return on investment (ROI) of your solar power system.

Grid Independence and Off-Grid Use

Battery energy storage is essential for off-grid solar systems, where there is no connection to the electricity grid. These systems rely entirely on solar energy and stored power for daily consumption. By using solar panels for generation and battery storage for backup, off-grid homes and businesses can operate independently, even in remote areas where grid infrastructure is unavailable. This setup provides autonomy and security, reducing the dependency on external power sources.

Supporting Grid Stability and Energy Management

In grid-tied solar systems, BESS helps stabilize the electrical grid. By storing excess solar energy and discharging it during peak demand times, battery storage systems contribute to grid balancing. This reduces the strain on the grid during periods of high demand, helping to ensure that energy is available when needed. Additionally, battery storage can mitigate the impact of energy fluctuations from renewable sources, like wind or solar, which can be intermittent.

Environmental Impact and Sustainability

Integrating battery storage with solar energy also promotes sustainability. By storing excess renewable energy, these systems reduce the need for fossil fuel-based backup generators or electricity from non-renewable sources. The combined use of solar power and battery storage lowers greenhouse gas emissions, supporting efforts to fight climate change and transition to clean energy solutions.

Conclusion

Battery Energy Storage Systems are a game-changer when it comes to solar energy integration. By efficiently storing excess solar energy and providing power when sunlight is not available, these systems enhance the reliability and efficiency of solar power. Whether for self-consumption, off-grid independence, or contributing to grid stability, battery storage is a crucial component in maximizing the potential of solar energy. With continued advancements in technology and affordability, battery energy storage is set to play a central role in creating a sustainable and resilient energy future.

Background of the Rise of Residential Energy Storage Systems

The world attaches great importance to renewable energy and smart grids. With the promotion of initiatives such as the “Million Solar Roofs Plan” in the United States and the “Energy Transition” in Germany, the government provides high subsidies for the private use of photovoltaic power. As a result, households can achieve self - sufficiency in electricity and store surplus electricity, which is particularly prominent in the residential energy storage market in Germany and Europe. In today's era of rapid development of intelligence and information, the global electricity demand is growing explosively, bringing energy supply, pollution and consumption problems. Photovoltaic power generation is favored around the world. Thanks to policy support and the reduction of power generation costs of photovoltaic energy storage technology, residential photovoltaic power generation and energy storage systems have entered thousands of households. It can not only help households achieve self - sufficiency in electricity and reduce dependence on traditional power grids, but also store electricity for emergencies during peak periods of low power consumption.

Basic Structure and Working Mode of Residential Energy Storage System

Grid - connected Residential Energy Storage System Components: Solar cell array (the core, which converts solar energy into direct current, considering conversion efficiency, etc.), grid - connected inverter (converts direct current into alternating current, is compatible with household electrical equipment, and monitors and manages the operating status of the system), BMS management system (monitors the status of the battery pack and balances charge and discharge), battery pack (stores electrical energy, and its capacity, etc. affect energy storage capacity and service life. Commonly used batteries include lead - acid batteries, lithium - ion batteries, etc.), AC load (household electrical appliances). Working Modes: Mode 1: Photovoltaic provides energy storage and surplus electricity to the grid; Mode 2: Photovoltaic provides energy storage and electricity for some users; Mode 3: Photovoltaic only provides partial energy storage and does not transmit power to the public grid.

Off - grid Residential Energy Storage System Main Components: Solar array, photovoltaic inverter (has more functions in an off - grid system), BMS management system, battery bank, AC load. Working Modes: Mode 1 (sunny days): Photovoltaic provides energy storage and user electricity; Mode 2 (cloudy days): Photovoltaic and energy storage batteries provide users with electricity; Mode 3 (evening and rainy days): The energy storage battery provides users with electricity. Off - grid systems are suitable for areas where the grid is unstable or unavailable, and have higher requirements for battery bank capacity and management systems.

The Role of Battery Management System (BMS) in Residential Energy Storage Systems

The BMS is the “brain” and is of crucial importance. Main Functions: Data collection and monitoring (collect key parameters and current through real - time communication between the BCU and BMU modules), state estimation (calculate the state of charge of the battery and the remaining battery power based on the collected data), user interaction (display the real - time battery status, etc. through user interfaces such as touch screens). System Intelligent Management: Intelligent interaction (the BCU intelligently interacts with other system components through an independent CAN bus), safety control (the BMS implements secondary protection of charge and discharge through relays. When abnormal, the power is cut off to ensure the isolation of strong and weak electricity).

The Core of the Power Solution of the BMS of the Energy Storage System: Isolation Voltage Conversion

The key to the power solution design of the BMS is safe and efficient isolation voltage conversion. When the main control unit is based on a 24VDC system and the power requirement is less than 5W, a suitable power supply product can be used. For example, a power supply product can output 5VDC voltage to power the isolation module and low - dropout linear regulator (LDO). The LDO converts the 5VDC voltage to 3.3V to power the microcontroller (MCU). Multiple isolation modules in the system provide power for the CAN communication module, voltage and insulation detection circuit, and current detection circuit, and isolate the power circuit from the signal circuit and communication module to reduce electromagnetic interference and improve stability. Automotive - grade power supplies are widely used in vehicle BMS systems for vehicle battery management due to their excellent performance and stability.

In short, the residential energy storage system is an important link between the home and new energy. Its structure, working mode, battery management and power solution play a key role in the efficient utilization, stable supply and sustainable development of home energy. With the continuous advancement of technology and the promotion of applications, the residential energy storage system is expected to play a greater value in the future energy field.

A Bilevel Equalizer for Lithium-Ion Batteries

Electric-powered vehicles such as drones (UAVs), Electric cars, electric scooters, Bus trucks, etc. are now in widespread use, and recent reports indicate their development is going to accelerate.

Virtually all these types of EVs now use lithium-ion batteries (LIB), but LIBs require electronic equalizer circuits (EQU) to balance the cell voltages. All present versions have cost and/or performance problems. However, a new type of SEMCO’s hybrid EQU called the Bilevel Equalizer (BEQ) has been proposed that avoids these problems.

Electric-powered aerospace and military vehicles such as drones (UAVs) are also undergoing intense development, and these use lithium-ion batteries (LIB) almost exclusively. However, all large LIBs require equalizer circuits (EQU) to balance the voltages of the series of connected cells (perhaps 200 or more), and all EQUs currently in use have certain cost and/or performance problems.

However, previous references have described a new type of hybrid EQU called the Bilevel Equalizer (BEQ) that mitigates these problems. This present study provides further insight into the BEQ design and proposes possible criteria that can be used for designing both the active and passive parts of the system.

Most large LIBs presently use passive equalizers (PEQ), which simply use a transistor to connect a resistor in parallel with each cell until it discharges to the same level as the lowest cell voltage in the pack. A typical circuit is shown in Fig. 1.

Fig. 1. Basic PEQ Circuit

PEQs are popular because they are simple and cheap, but heating and energy loss are obvious disadvantages. PEQs also are of no use during discharge since they cannot transfer charge to lower voltage, and thus the Ah discharge capacity of the battery is equal to that of the worst cell in a pack of perhaps 200-300 cells.

This problem is usually not important when the cells are new and well-balanced, but as they age, large variations develop, and the loss in discharge capacity due to even 1 or 2 weak cells can become serious.

This reduces the useful life of the battery, which of course increases the lifetime cost. PEQ heating problems also must be considered. This severely limits the size of the equalization currents, typically to less than 200-300 mA, and this limits the ability of the PEQ to equalize the pack when large imbalances are present.

There are several types of active equalizers (AEQ) that transfer charge between cells and thus avoid the problems with PEQs, but they are rarely used due to their complexity and much higher cost. All of these prove to be expensive even for modest AEQ currents, and the cost becomes prohibitive for the higher AEQ currents that are required for large cell imbalances and load currents.

The limitations of PEQs are widely recognized, but since presently available AEQs bring new cost and complexity problems, designers of battery management systems (BMS) have avoided them. Another problem is system inertia. Once a company has an operational BMS with a PEQ, they are reluctant to change, especially if the advantages of an AEQ do not become important until after a few years of service. Thus, these problems persist, and if left uncorrected they will degrade the lifetime performance of these large LIB applications.

BILEVEL EQUALIZER

This quandary has motivated the design of a new EQU that provides performance close to an AEQ but with only a modest cost increase above a PEQ. This circuit is a hybrid AEQ/PEQ called the Bilevel Equalizer (BEQ) because it provides equalization at two different voltage levels. In this system, the battery is organized into sections of a series of connected cells. The AEQ portion balances the section voltages, and there is a PEQ for each section which balances the section cells. This is especially advantageous for large applications such as those for electric aerospace vehicles because the BEQ can be implemented by adding an AEQ to an existing PEQ system with only minor changes to the original hardware. Fig. 2 (a) shows the AEQ circuit that constitutes the active part of the BEQ.

(a) Schematic

(b) Current in L1

In this system B1 – B3 represent sections of a series of connected cells. The number of cells/sections is usually 4 to 14, and for sections of 12 -14 cells, the efficiency is typically in the range of 85 to 90%. Components Q1, Q2, and L1 constitute one AEQ unit, so this circuit has 2 units. To transfer charge from B1 to B2, Q1 is turned on for 0 < t < t1, and i1 flows into L1. At t1, Q1 turns off and i1 flows from L1 into B2 via the body diode of Q2. The period t2 – t1 is less than t1 because of a slight gap in the FET gate drive signal and parasitic losses.

Since the B’s can consist of any number of cells, a 196-cell battery might be organized into 14 sections of 14 cells each. This would only require 13 AEQ units (number of sections ��� 1), whereas an AEQ with a bidirectional DC-DC converter for each cell would require 196 AEQ units. Therefore, if both types are operated at the same value of equalization current, the cost of the AEQ in the BEQ will be much lower than using an AEQ for each cell.

Another important cost advantage is the absence of the transformers that are present in virtually all other AEQs. AEQs with a DC-DC converter for each cell are presently limited to EQU currents less than 1 Adc, and they are still quite expensive even at these low current levels. Currents in this range also are inadequate for larger batteries that might require EQU currents in the range of 5 Adc or more. Because of its relative simplicity and the low number of AEQ units, the circuit in Fig. 1 can easily be designed to economically provide equalization currents in these higher current ranges.

The block diagram of a BEQ where the cells are divided into 5 sections is shown in Fig. 3. This might represent a 60-cell LIB with 12 cells/section and a maximum voltage of about 240 Vdc. This system uses a PEQ for each section to provide equalization at the cell level for the cells in that section. AEQ units identical to those in Fig. 2 (a) are used to equalize the section voltages. The AEQ boxes shown in blue in Fig. 3 are the only new hardware items needed to convert a PEQ to a BEQ.

Fig. 3. BEQ for a Battery with 5 Sections of Cells

Although the conversion of a PEQ to a BEQ does not require any significant hardware changes, it does require new software since the equalization strategy is different, e.g., the PEQs now drain the cells to the lowest cell voltage in each 12-cell section instead of the entire pack.

Conclusion

Despite their power losses and lack of equalization during discharge, PEQs remain the most common type of EQU due to their lower cost. AEQs provide much better performance, but they are rarely used because of high cost and complexity. This present study, alone, shows that SEMCO’s BEQ hybrid provides an attractive solution since its performance for large imbalances is much better than a PEQ, and its much lower component count and absence of transformers indicate a much lower cost than an AEQ of equivalent size.

The Charging and Discharging Process of Electric Vehicle Batteries

Electric cars (EVs) are revolutionizing the automotive industry with their eco-friendly and sustainable mode of transportation. The key to EVs is their power batteries, which undergo a complex yet crucial charging and discharging process.

Understanding these processes is crucial to grasping how EVs efficiently store and use electrical energy. This article will explore the intricate workings of the charging and discharging processes that drive the electric revolution.

Charging Process:-

Power Connection: To begin the charging process, the electric vehicle is linked to a power source, usually a charging pile or a charging station. These charging points supply the required current and voltage to transfer electrical energy to the vehicle's battery pack.

Battery Management System (BMS) Control: The Battery Management System (BMS) plays a crucial role throughout the charging process. It closely monitors and controls different battery parameters like voltage, temperature, and current. The main goal of the BMS is to safely charge the battery within set limits, preventing overcharging and overheating.

Charging Process: When the vehicle links to the power source, a chemical reaction starts inside the battery. Electrons move from the negative electrode to the positive electrode, and lithium ions travel from the positive electrode to the negative electrode. This complex redox reaction efficiently converts electrical energy into chemical energy, storing it within the battery.

Charging Rate: The charging rate differs based on the battery's design and the capabilities of the power supply. Fast-charging systems can provide a significant amount of power in a short period, with some reaching an 80 percent charge in just 30 minutes. However, it's crucial to carefully handle the charging process to avoid overheating, as this can negatively impact battery health.

Discharge Process:-

Electric Drive Requirements: When the electric vehicle is ready to operate or perform other tasks, the Battery Management System (BMS) takes control. The BMS determines the suitable discharge rate based on the vehicle's operational requirements.

Discharge Process: During the discharge process, the battery's chemical reactions undergo a reversal. Lithium ions migrate from the negative electrode to the positive electrode, while electrons travel from the negative electrode to the positive electrode. This electron movement generates an electric current, which powers the electric motor responsible for propelling the vehicle.

Battery Condition Monitoring: To maintain battery health and performance, constant attention is necessary. The BMS continually observes the battery's status, ensuring cell balance, and stable voltage, and preventing over-discharge. These steps are crucial for prolonging the battery's lifespan and preserving its abilities.

Energy Release: The primary result of the discharge process is the release of electrical energy to operate the electric vehicle. The discharge rate is determined by the vehicle's acceleration and power requirements, along with the battery's design.

Conclusion

The charging and discharging processes are the vital components of power batteries in electric vehicles. They enable the storage and conversion of electrical energy, offering a sustainable power solution for the EV revolution.

Amidst this intricate journey, the Battery Management System (BMS) serves as the protector of safety, stability, and efficiency, ensuring the battery operates securely and efficiently. As the electric vehicle industry progresses, a deeper comprehension of these processes will undoubtedly propel further advancements in EV technology, promising a greener and more sustainable future for transportation.
