As the core component of energy storage equipment, the safety of battery pack has attracted much attention. In the actual use process, the battery pack may have potential safety hazards such as capacity attenuation, increased internal resistance, and temperature increase, which will seriously affect the performance and life of the battery pack.
In order to solve these potential safety hazards, the battery pack charging and discharging aging cabinet came into being.
First of all, the battery pack charge and discharge aging cabinet can find the potential safety hazards of the battery pack in advance by simulating the charge and discharge cycle process of the battery pack in actual use.
During the charging and discharging cycle, the battery pack will generate a lot of heat, and if the heat dissipation of the battery pack is poor or the temperature control is not accurate, it is easy to cause safety problems such as overheating and thermal runaway of the battery pack. By carrying out a long-term and high-intensity charge-discharge cycle test in the charge-discharge aging cabinet, the high temperature conditions that may occur in the actual use of the battery pack can be simulated, so as to detect whether the heat dissipation performance and temperature control of the battery pack are qualified in time.
Secondly, the battery pack charge and discharge aging cabinet can also detect potential safety hazards such as capacity attenuation and internal resistance increase of the battery pack.
As the battery pack is used for more time, its capacity will gradually decrease, and the internal resistance will gradually increase, which will lead to a decrease in the battery pack's endurance, reduced discharge efficiency, and may even cause safety problems such as short circuit and overheating of the battery pack. The charge-discharge aging cabinet can monitor and evaluate the capacity attenuation and internal resistance increase of the battery pack through the cyclic charge-discharge process, and find and solve these potential safety hazards in time.
In addition, the battery pack charge and discharge aging cabinet can also evaluate the life and stability of the battery pack.
Through long-term, high-intensity charge-discharge cycle testing, the working state of the battery pack in actual use can be simulated, the life and stability of the battery pack can be evaluated, and the subsequent product design and reliability analysis can be provided. At the same time, the charge-discharge aging cabinet can also test and compare different types and specifications of battery packs, evaluate their performance differences, and provide reference for users to choose the right battery pack.
By simulating the charge-discharge cycle process of the battery pack in actual use, the battery pack charging and discharging aging cabinet can find the potential safety hazards of the battery pack in advance, such as heat dissipation problems, capacity attenuation, internal resistance increase, etc., and evaluate the life and stability of the battery pack. The application of these functions helps to ensure the safety and reliability of the battery pack and improve its application effect in the field of new energy. Therefore, the battery pack charge and discharge aging cabinet is one of the important equipment to solve the potential safety hazards of the battery pack.
