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.

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...

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.

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.

Mar 22, 2024 Neighbors suspect that photovoltaic modules have light pollution? Here comes the expert explanation!

Mr. Li, who lives in Fujian, wants to install a set of photovoltaic power stations in his home, and wants to realize that electricity does not cost money, but can also generate electricity to make money, should be happy, but let him worry, why is this? It turns out that the neighbors come over every three and a half times to pass on the information: photovoltaic modules have light pollution, which will affect the surrounding neighbors. Later, Mr. Li found a local industry expert and got a professional answer, only to know that the truth is not like the neighbors said. So, is there light pollution in the photovoltaic module? Will it affect People's Daily lives? 01 Light pollution Light pollution is a new environmental pollution source after waste gas, waste water, waste residue and noise pollution, which mainly includes white pollution, artificial day pollution and color pollution. In daily life, people's common light pollution is mostly caused by the vertigo of pedestrians and drivers caused by the reflection of mirror buildings, and the discomfort caused by unreasonable lighting at night. 02 Glare Glare refers to a visual condition that causes visual discomfort and reduces the visibility of objects due to inappropriate brightness distribution or extreme brightness contrast in space or time in the field of view. Glare can be divided into direct glare and reflected glare, and reflected glare is directly related to the reflectivity of the target object. 03 Comparison of reflectance of solar photovoltaic modules with that of common surface objects Photovoltaic module is the core equipment for photoelectric conversion in the process of solar photovoltaic power generation. In order to improve the conversion efficiency, the surface of the glass cover plate used in the production process of the module is generally suede-treated and coated with anti-reflection film, and the surface of the silicon is textured and anti-reflection film, which has achieved the increase of the transmission rate of the glass cover plate and the absorption rate of the crystalline silicon. The surface of the photovoltaic module is tempered glass, the surface is not mirror, there will be only slight diffuse reflection, and there is no light pollution. In fact, the visible light reflection coefficient of ordinary tempered glass is 9% to 11%, which will not cause light pollution, and the BIPV component uses the same type of glass as the building, which will not cause light pollution. The source of light pollution is visible light, and the internal power generation unit battery of the BIPV module will absorb visible light and convert it into electricity, which will further reduce the reflection of visible light. So photovoltaic power generation system is no light pollution.

Mar 21, 2024 What determines the amount of electricity generated by a rooftop power station?

For photovoltaic power stations, every additional kilowatt hour of electricity generated means more revenue per kilowatt hour of electricity. Many people believe that photovoltaic power stations of the same size should have the same power generation capacity. In fact, there are many determining factors. Lighting and environmental impact in the area Photovoltaic power stations rely on solar radiation to generate electricity. The greater the intensity of solar radiation, the higher the power generation capacity of the photovoltaic power station. Data show that more than 2/3 of the regions in my country have more than 2,000 hours of sunshine per year and are rich in solar energy resources. Depending on the latitude and the amount of solar radiation, the power generation capacity of the photovoltaic power station is determined. In addition to differences in solar energy resources, the humidity and temperature in various regions will affect the power generation of photovoltaic power stations. In particular, particulate matter in air pollution, also known as smog, can reduce photovoltaic power generation efficiency by more than 17%. According to calculations, in hazy cities, the power generation of photovoltaic power stations is obviously low. And when the haze is severe, photovoltaic power stations cannot even generate electricity. Quality factors of photovoltaic power plants Environmental problems are difficult to change, but a high-quality photovoltaic power station will definitely generate more electricity than a low-quality power station. Various devices, from silicon materials to components, and from components to inverters, all play a decisive role in power generation. Photovoltaic module quality As the core component of a photovoltaic power station, the quality of photovoltaic modules plays a decisive role in the power generation capacity of the power station. The quality of photovoltaic modules is ultimately linked to their service life and efficiency. First of all, the photoelectric conversion efficiency of photovoltaic modules represents the power generation capacity of the module, so the higher the efficiency of the module, the higher the power generation capacity of the power station. In addition to efficiency, the quality of photovoltaic modules is more reflected in various aspects such as anti-attenuation and anti-aging. Inferior photovoltaic modules are prone to problems such as cracks and backplane aging. Once such problems occur, the efficiency of the photovoltaic modules will drop significantly, resulting in low power generation of the power station. What's more, it is also very important that many power station users do not understand the operating principles of photovoltaic power stations and use them as boards to dry things, such as quilts, shoes, dried food, and peppers... This will block the components and affect the conversion of solar energy into current. If it is small, it will reduce the income of power generation; if it is ...
