Structural design: Rack mounted lithium batteries are generally composed of multiple battery modules, which are usually designed in a standardized manner for easy installation and disassembly. Each battery module contains multiple lithium-ion battery cells connected in series or parallel to meet different voltage and capacity requirements. The battery module is also equipped with a Battery Management System (BMS) for monitoring and managing the status of the battery, including parameters such as voltage, current, temperature, etc., to ensure safe operation and performance optimization of the battery. In addition, the entire rack mounted lithium battery system also includes a casing, heat dissipation device, electrical connection components, etc., to provide good physical protection and electrical connections

The inverter aging workshop is a test environment specially designed to simulate extreme working conditions (such as high temperature and high humidity). By accelerating the product aging process, the reliability and stability of the inverter in long-term use are verified. Its core components include:‌Environmental simulation system‌The electric heating element and temperature control system can accurately adjust the temperature within the range of 30℃-70℃, and are equipped with ventilation devices to ensure uniform temperature distribution.Integrated humidity control module supports aging tests under different humidity conditions.‌Monitoring and protection mechanism‌The built-in sensor collects voltage, current, temperature and other data in real time, and automatically triggers overvoltage/overcurrent protection when abnormal.Equipped with emergency door opening device and air pressure balance system to ensure safe operation

Basic parametersVoltage: 51.2V is the nominal voltage of this lithium battery pack. In practical use, the terminal voltage of the battery will change with the charging and discharging process. During charging, the voltage will gradually increase to around 56V (full charge voltage), and during discharging, the voltage will gradually decrease. When the voltage drops to a certain level (such as around 42V), it usually indicates that the battery is approaching the end of discharge state.Capacity: 200Ah represents the rated capacity of the battery, which is the amount of charge that the battery can release under certain discharge conditions. Taking a constant current discharge of 20A as an example, theoretically it can last for 10 hours of continuous discharge. The actual available capacity of a battery may be affected by factors such as temperature, charge discharge rate, etc.Battery compositionBattery cell: usually composed of multiple lithium-ion battery cells connected in series and ...

Structure and PrincipleStructure: It mainly consists of a positive electrode plate, a negative electrode plate, an electrolyte, a separator, and a battery casing. The active material on the positive electrode plate is lead dioxide (PbO ₂), the active material on the negative electrode plate is sponge like lead (Pb), and the electrolyte is sulfuric acid (H ₂ SO ₄) aqueous solution.Working principle: During charging, electrical energy is converted into chemical energy, converting lead sulfate into lead dioxide and lead, while the concentration of sulfuric acid in the electrolyte increases. During discharge, chemical energy is converted into electrical energy. Lead dioxide on the positive electrode plate and lead on the negative electrode plate react with sulfuric acid in the electrolyte to produce lead sulfate and water, resulting in a decrease in sulfuric acid concentration.
