Battery protection boards are designed to protect batteries. But many people do not understand the specific functions of these protection boards. The following is a discussion of the functions of battery protection boards. 1. Overcharge protection function: When the battery reaches a certain voltage, the charger is disabled to prevent overcharging. Instead of other words, the tube controlling overcharge will be out-of-work, so that the purpose of stopping the charge is achieved.   2. Over-discharge protection function: Over-discharge protection function: When the battery voltage reaches a certain low level, the discharge process stops, protecting the battery and preventing over-discharging. 3. Over-current protection function: When a large current is consumed, the battery stops discharging to ensure safe operation. After the overcurrent detection, the battery returns to normal after it is separated from the load and can be recharged or discharged . 4. Short circuit protec

Battery Introduction In the battery sector, three main battery types are widely used and dominate the market: cylindrical, square and pouch. These cell types have unique characteristics and offer various advantages. In this article, we will explore the characteristics of each cell type and compare them based on various factors. 1. Cylindrical battery core Advantage: - Mature and cost-effective: Cylindrical batteries have been in industrial production for more than 20 years, with mature manufacturing processes and high production efficiency. This means lower costs and higher product yields compared to other cell types. - Excellent reliability and safety: Cylindrical batteries offer excellent reliability and safety due to their extensively tested production methods and their steel casing for extra protection. Disadvantages: - Weight and size: The steel casing used in cylindrical batteries adds weight, resulting in lower energy density compared to other battery types. Furt

In the new era of power systems, energy storage has become a crucial component for ensuring the integration of renewable energy sources and ensuring grid stability. It finds applications in power generation, grid management, and end-user consumption, making it a highly sought-after technology. This article aims to evaluate and analyze the cost composition, current development status, and future prospects of lithium-ion battery energy storage. Cost Composition of Energy Storage Batteries: The cost of energy storage systems primarily consists of five components: battery modules, Battery Management Systems (BMS), containers (including Power Conversion Systems), civil construction and installation costs, and other design and debugging expenses. Taking a 3MW/6.88MWh energy storage system in a factory in Zhejiang Province as an example, battery modules account for 55% of the total cost. Battery Technology Comparison: The lithium-ion energy storage industry chain consists

Ternary lithium battery is a common type of rechargeable battery. It realizes the charging and discharging process by the repeated intercalation and deintercalation of lithium ions between the positive and negative electrodes. Compared with other types of lithium-ion batteries , ternary lithium batteries have higher energy density and better cycle life, so they have been widely used in many application fields, such as electric vehicles, portable electronic devices, etc. However, ternary lithium batteries also need to follow the corresponding precautions to ensure their safety and performance. The following are some precautions when using ternary lithium batteries: Charging: Charge using the recommended charger and cable and follow the manufacturer's charging guidelines. Do not use unsuitable or low-quality charging equipment, so as not to cause problems such as overcharging, over-discharging or overheating. Temperature Control: Avoid placing the battery in a high o

The battery is the main power source of the product. It can drive the operation of the equipment. Using test tools to conduct detailed inspections on the battery can ensure the safety of the battery and prevent the battery from spontaneous combustion and explosion due to excessive temperature. 1. Cycle life The number of cycles of a lithium battery reflects how many times the battery can be repeatedly charged and discharged. According to the environment in which the lithium battery is used, the cycle life can test the cycle life of the battery at low temperature, normal temperature and high temperature. Usually, the waste standard of the battery is selected according to the use of the battery. If the battery is used for power batteries (electric vehicles, electric forklifts), etc., the discharge capacity maintenance rate of 80% is generally selected as the standard parameter for waste. If the battery is used for energy storage, Storage, etc. can be relaxed to 60%. 2. Ma

Special lithium batteries refer to a special type of lithium battery technology, which are different from traditional lithium-ion batteries (Li-ion) in terms of electrochemical performance, structural design, and material composition. Compared with civilian lithium-ion batteries, special lithium-ion batteries usually have the characteristics of high energy density, high power output, long cycle life, high safety and stability. Specific types of special lithium batteries include lithium polymer batteries, lithium sulfur batteries, lithium air batteries, lithium titanate batteries, etc.: Lithium-polymer battery (Li-Polymer) : Similar to lithium-ion batteries, but uses a polymer matrix instead of a liquid electrolyte, which has higher energy density and flexibility. Lithium iron phosphate battery (LiFePO4) : Using lithium iron phosphate as the positive electrode material, it has high safety, long cycle life and low energy density. Lithium-sulfur battery (Li-S) : Using sulfu

The 18650 lithium battery is a type of lithium-ion battery and a pioneer of lithium-ion batteries. There are many situations where the 18650 battery cannot be charged, and it is necessary to take corresponding repair methods to effectively solve the problem that the 18650 battery cannot be charged. So what are the reasons and solutions for the battery not charging? The possible reasons why the 18650 lithium battery cannot be charged are as follows: Poor battery contact: If the battery is not in good contact with the charger, the battery cannot be charged. At this time, you need to check whether the battery is in good contact with the charger plug, or try to replace the charger and battery. Incorrect battery polarity: If the battery is inserted backwards into the charger, the battery will also not charge. The correct operation is to connect the positive terminal of the battery to the positive terminal of the charger, and the negative terminal of the battery to the nega
