European energy storage Market Analysis to 2024
Apr 16, 2021 European energy storage Market Analysis to 2024
Looking at European energy storage from the German household storage market: maintaining cautious optimism According to EESA's forecast, the overall household savings scale in Europe in 2023 will be approximately 9.2GWh, and the German household savings market accounts for 47% of Europe's total scale, which has strong guiding significance. The cumulative installed capacity of energy storage in Germany will reach 7.4GW/11.5GWh in 2023, an increase of 3.5GW/5.3GWh from the end of 2022. The growth rate gradually slowed down in the second half of the year, from more than 200% in the middle of the year to -23% in December. In January 2024, Germany added 35.7MWh of large-scale storage capacity, 18.1MWh of industrial and commercial capacity, and 333.0MWh of household storage capacity; a total of 386.8MWh was added in the month, -10% year-on-year. The year-on-year growth rate is in a continuous downward trend, and has been negative for three consecutive months, confirming our previous cautious predictions for European energy storage. European electricity prices generally fall, and the impact of natural gas decreases According to TRADINGECONOMICS, the electricity prices of Germany, Italy, and the United Kingdom, the top three energy storage installed countries in Europe, are 68.54/95.75/61.00 euros/MWh respectively. Although there are certain price fluctuations on a monthly basis, they are at a lower level than the peak during the energy crisis in 2022. Low shock. The natural gas price index quoted $1.6822/MMBtu last Friday and will continue to trend downward after the year. In the short term, it will be difficult for European electricity prices to rise significantly. Energy storage subsidy policy maintains bottom line for household storage demand in Europe Fluctuations in European electricity prices determine the upper limit of energy storage demand, while the subsidy intensity and stability of European policies maintain the lower limit of energy storage demand. Taking Italy as an example, from February to April 2023, the government suspended the Superbonus subsidy plan due to deficit pressure, and reduced the Superbonus subsidy intensity in 2024 and 2025 after restarting, causing construction at thousands of construction sites to come to a standstill. In the end, the government had to extend the Superbonus scheme to a limited extent. It can be seen that the current European energy storage market demand is relatively fragile and highly dependent on policies. Current policy disturbances will become the core contradiction of European energy storage demand.

Off-Grid Solar Systems: Self-Sufficient Energy Solutions
Apr 16, 2024 Off-Grid Solar Systems: Self-Sufficient Energy Solutions
Off-Grid Solar Systems Self-Sufficient Energy Solutions Photovoltaic off-grid systems not only provide a way to disconnect from the traditional grid, but also bring new possibilities to users in remote areas or who want to reduce their dependence on the public grid. This article takes an in-depth look at how off-grid solar systems work, their key components, and how they can become an important part of modern sustainable energy solutions. 01. What is an off-grid solar system? Off-grid solar systems, as the name suggests, are independently operating solar systems that do not rely on the traditional power grid. The core components of these systems include solar panels, battery packs, battery management systems (BMS) and inverters. Solar panels are responsible for capturing sunlight and converting it into electrical energy, while batteries are used to store this electrical energy for use when the sun is low or at night. The charge controller ensures that the battery is charged and discharged in a safe and efficient manner, while the inverter converts the DC power stored in the battery into AC power that can be used in the home or business. Off-grid systems are particularly suitable for remote areas or for those who want to be more self-sufficient, providing a means of energy supply that is independent of the traditional grid. 02. Core components of off-grid solar systems When delving into off-grid solar systems, it’s crucial to understand their core components. In this article, we will focus on off-grid solar power plants. Small off-grid solar systems such as solar lamps and lawn lamps are beyond the scope of this article. Off-grid solar power plants are made up of several key parts, each playing an integral role. The following are the main components of an off-grid solar power plant: 1. Solar panels: The core of the power station, responsible for capturing solar energy and converting it into electricity. The quality, efficiency and quantity of battery panels directly determine the overall performance of the power station. 2. Battery Management System (BMS): BMS is a key component of the power station and is responsible for managing the current sent to the battery pack to prevent the battery from overcharging or over-discharging and ensuring the long-term health and efficiency of the battery pack. 3. Battery bank: used to store the energy generated by solar panels during the day for use when there is no sunlight or when demand is peak. The type, capacity and number of batteries will determine the energy storage capacity of the plant. 4. Inverter: Converts DC power stored in the battery into AC power that can be used in a home or business. 5. Bracket and mounting system: To maximize the efficiency of solar panels, a stable and appropriately angled bracket system is required to mount the solar panels. 6. Monitoring systems: Modern off-grid power plants often include smart monitoring systems to track the performance of the plant in real time and make a...

Why do lithium batteries need BMS?
Apr 11, 2024 Why do lithium batteries need BMS?
As the core energy component of electric vehicles and various portable electronic devices, lithium batteries have become the first choice for modern energy solutions due to their high energy density, lightweight characteristics and good charging performance.However, the delicate nature of lithium batteries also places higher safety and performance requirements on their use. This is why the Battery Management System (BMS) has become a key technology to ensure the safety, efficiency and life of lithium batteries. 一.The necessity of security requirements The safety risks of lithium batteries are mainly reflected in three aspects: overcharge, over-discharge and overheating.In an overcharged state, metallic lithium may be produced inside the lithium battery, increasing the risk of thermal runaway, which may cause the battery to rupture or even explode.On the contrary, excessive discharge may cause irreversible damage to the battery's internal structure, thereby permanently reducing the battery's capacity and service life.In addition, when lithium batteries operate in high-temperature environments, their chemical reactions accelerate, further exacerbating the risk of thermal runaway.Therefore, BMS monitors the voltage, current and temperature of the battery in real time and strictly controls the charging and discharging process to effectively prevent these risks and ensure the safe use of lithium batteries. 二. Diversity of functional requirement 1. Real-time monitoring of SOC Accurate information on battery status is crucial for convenient and efficient battery use.SOC (State of Charge, battery state of charge), one of the state quantities, reflects the remaining power of the battery and is of great significance for estimating the battery's cruising range and managing battery charging and discharging strategies.BMS uses high-precision algorithms to calculate and update SOC values in real time, providing users with accurate battery usage information to meet customers' needs for application performance.   2. Balanced management There are inevitable inconsistencies between battery cells in lithium battery packs. This inconsistency increases as the battery usage time increases, ultimately affecting the performance and life of the entire battery pack.By implementing a dynamic balancing strategy, BMS makes timely adjustments to the individual cells in the battery pack to maintain voltage consistency between cells, thereby improving the overall performance of the battery pack and extending its service life.   3. Temperature management The optimal operating temperature range of lithium-ion batteries is 25°C to 40°C. To sum up, the reason why lithium batteries require BMS is because BMS can not only effectively prevent and reduce the safety risks that may occur during the use of lithium batteries, but also optimize the working performance of the battery and extend the service life of the battery through refined management.

Detailed explanation of 5 major energy storage battery parameters
Apr 10, 2024 Detailed explanation of 5 major energy storage battery parameters
Content source: Energy Storage Technology School Batteries are one of the most important parts of electrochemical energy storage systems. With the reduction of battery costs and the improvement of battery energy density, safety and lifespan, energy storage has also ushered in large-scale applications. This article will help you understand energy storage Several important parameters of the battery. 01. Battery capacity Battery capacity is one of the important performance indicators for measuring battery performance. The capacity of a battery is divided into rated capacity and actual capacity. Under certain conditions (discharge rate, temperature, termination voltage, etc.), the amount of electricity released by the battery is called rated capacity (or Nominal capacity). Common units of capacity are mAh and Ah=1000mAh. Taking a 48V, 50Ah battery as an example, it means that the battery capacity is 48V×50Ah=2400Wh, which is 2.4 kilowatt-hours of electricity. 02. Battery discharge C rate C is used to indicate the battery charge and discharge capacity rate. Charge and discharge rate = charge and discharge current/rated capacity. For example: when a battery with a rated capacity of 100Ah is discharged at 50A, its discharge rate is 0.5C. 1C, 2C, and 0.5C are battery discharge rates, which are a measure of discharge speed. If the used capacity is discharged in 1 hour, it is called 1C discharge; if it is discharged in 2 hours, it is called 1/2=0.5C discharge. Generally, the capacity of the battery can be detected through different discharge currents. For a 24Ah battery, the 1C discharge current is 24A and the 0.5C discharge current is 12A. The larger the discharge current. The discharge time is also shorter. Usually when talking about the scale of an energy storage system, it is expressed by the maximum power of the system/system capacity (KW/KWh). For example, the scale of an energy storage power station is 500KW/1MWh. Here 500KW refers to the maximum charge and discharge of the energy storage system. Power, 1MWh refers to the system capacity of the power station. If the power is discharged with a rated power of 500KW, the capacity of the power station is discharged in 2 hours, and the discharge rate is 0.5C. 03. SOC (State of Charge) state of charge The battery's state of charge in English is State of Charge, or SOC for short. It refers to the ratio of the remaining capacity of the battery after it has been used for a period of time or left unused for a long time and its capacity in the fully charged state. It is usually expressed as a percentage. Simply put, it is the remaining capacity of the battery. 04. DOD (Depth of Discharge) depth of discharge Depth of Discharge (DOD) is used to measure the percentage between battery discharge and battery rated capacity. For the same battery, the set DOD depth is inversely proportional to the battery cycle life. The deeper the discharge depth, the shorter the battery cycle life. Therefore, it is important to bala...

What is lithium battery cell capacity classification? what's the effect?
Apr 09, 2024 What is lithium battery cell capacity classification? what's the effect?
What is lithium battery cell capacity classification? what's the effect? What is the composition of lithium batteries? What is the role of the chemical composition of lithium batteries? As the power source of future electric vehicles and energy storage, lithium batteries need to be formed and divided into cells during the production process to ensure the quality and quality of the final power supply product. 1. What is formation and classification The lithium battery has no power when assembly is completed and must be charged to activate. The first charge is called 'formation' and is used to activate the active materials in the battery body. Formation, also called 'activation', is a very complex process, and it is also an important process that affects battery performance, because during the first charging process of the battery, it is inevitable to form at the interface between the carbon negative electrode and the electrolyte. The thin passivation layer covering the surface of the carbon electrode is called the solid electrolyte interface film or SEI film. The capacity of the battery is determined by charging and discharging the battery and detecting the discharge capacity when the capacity is fully charged. Only batteries whose tested capacity meets or exceeds the design capacity are qualified. This process of selecting qualified batteries through capacity testing is called capacity classification. 2. The role of formation and  classification The formation, volume fractionation and detection system are the most critical links in the back-end process. The chemical composition of lithium battery cells is achieved by charging and discharging to activate the active material of the battery cells, which is an energy conversion process. The composition and capacity principle of lithium battery cells is relatively complex, but it is also an important process that affects battery performance. The power connector serves as a connection switch between the battery and the outside and also affects the performance of the battery. High-quality battery terminals allow lithium batteries to be used effectively. Formation is just a charging process, and there is no need to discharge the battery core. Therefore, a separate charger can be used during formation, so the charger is often called a forming machine or a forming cabinet. Although formation does not require discharge, the formation process of some cells requires more than one charge. The capacity dividing process immediately after formation requires charging and then discharging the cells. After formation and charging, the cells must also be discharged. This technological need has also led many battery manufacturers to directly use charge and discharge machines with charging and discharging functions for formation.

What are the benefits of photovoltaic elderly care?
Mar 28, 2024 What are the benefits of photovoltaic elderly care?
Photovoltaic elderly care is a new type of elderly care model. "People's Daily" has long recommended the "photovoltaic elderly care" model. This report published in December 2015 described it this way: "Most people in the village invest in rooftop power stations with For elderly care, rooftop power stations have low investment, low risk, and stable income." Village Party Secretary Jiang Hongliang pointed out the reason in one sentence. In fact, the construction of household photovoltaic power stations can be regarded as an investment behavior, with a rate of return of more than 10%! Nowadays, the country is vigorously supporting distributed photovoltaics. Most areas in our country can pay back their costs in a few years. Areas with strong local subsidies will have even shorter time to pay back their costs. The remaining ten years of power generation income will be a steady collection of money. What are the benefits of photovoltaic elderly care? Utilizing idle resources, the elderly do not need to work Home distributed use uses the idle roof resources of the home to install photovoltaic power stations to convert solar energy into electrical energy. As long as it is installed and connected to the grid, you can immediately gain income and enjoy national and local photovoltaic subsidies. It can be said that by lying on the roof and basking in the sun, photovoltaic modules can generate real income every day. With this small vault on the roof, parents no longer have to go to the fields to farm, they can easily reap the benefits of sunlight and retire at home with peace of mind!   Small investment and high returns In most areas of my country, the payback time is 6 to 8 years. In areas with strong local subsidies, the cost can be recovered in less than 5 years, and the income from power generation in the remaining ten years will be collected steadily! Warm in winter and cool in summer to save electricity bills Actual cases show that household photovoltaic power stations on the roof have a certain thermal insulation effect. In summer, the indoor temperature of a photovoltaic roof can be reduced by 3 to 5 degrees. While the indoor temperature is controlled, the energy consumption of the air conditioner can also be significantly reduced!   Not subject to geographical restrictions on resource distribution Solar photovoltaics are not restricted by the geographical distribution of resources. As long as there is sunshine, you can install a home photovoltaic power station. It has a wide range of uses in China and is suitable for various areas in my country, especially remote areas without electricity and areas with complex terrain. It can solve the problem of empty-nest elderly care in most areas of my country.It is precisely because of these advantages that photovoltaic power plants are currently widely promoted in rural areas and have become a new choice for elderly people in rural areas.

Mar 26, 2024 Analysis and prospects of new energy storage technology routes
Content source: ESPlaza long-term energy storage network Achieving carbon peak carbon neutrality and striving to build a clean, low-carbon, safe and efficient energy system are major decisions and arrangements made by the Party Central Committee and the State Council. New energy storage is an important support to help achieve the "double carbon" goal, an important means to ensure the security of energy supply, a key element in building a new power system, and an important direction for cultivating strategic emerging industries, with broad development prospects. This article aims to analyze and compare the technical characteristics and application scenarios of the main technical routes of new energy storage, and on this basis, forecast the future development trend of new energy storage. 1 Overview of new energy storage development The development history of energy storage technology can be traced back to the early 19th century, when people began to explore methods of converting electrical energy into chemical energy, thermal energy and other forms for storage. It was not until the early 20th century that electrochemical energy storage technology represented by lead-acid batteries began to become popular, providing a reliable means for energy storage and utilization. With the advancement of science and technology and the application of new materials, energy storage technology has been constantly innovated and improved. New electrochemical energy storage technology represented by lithium-ion batteries has emerged. Its advantages such as high energy density, long life, environmental protection and no pollution have been favored by It has been widely recognized and has become the current mainstream energy storage technology. Although the scale of new energy storage installed capacity is growing rapidly, the development of new energy storage still faces problems such as high costs, lack of a price mechanism, imperfect standards and regulations, and difficulty in project implementation. 2 Main technical routes for new energy storage New energy storage mainly includes three major technical paths: electricity storage (electrochemical energy storage, mechanical energy storage, and electromagnetic energy storage), hydrogen storage, and heat storage. Compared with pumped hydro energy storage, new energy storage has the advantages of short construction period, simple and flexible site selection, and strong adjustment capabilities. It is better matched with new energy development and consumption, and its advantages are gradually becoming more and more prominent. 2.1 Electricity storage Electricity storage can be divided into three categories: electrochemical energy storage, mechanical energy storage and electromagnetic energy storage. Electrochemical energy storage mainly includes lithium-ion batteries, flow batteries, lead-acid batteries and sodium-ion batteries; mechanical energy storage mainly includes compressed air energy storage, flywheel energy storage ...
