　　What are the impacts and advantages of the UPS lithium battery management system? The intelligent management and use of UPS lithium batteries is a prerequisite for ensuring the safe operation of lithium batteries.

　　UPS lithium batteries generally have four working modes, which are reset, charging and discharging, cooling and heating, idle and working. The lithium battery pack obtains electrical energy from an external power source for charging and discharging through the battery management interface.

　　Impact of battery management system

　　Even with the management of the battery management system, as the use time increases, the heating rate, heating process, temperature maintenance time and cooling rate of the lithium battery pack will still have an impact on the performance of the lithium battery pack, which will affect the performance of the lithium battery pack. The overall capacity produces a cumulative error.

　　Since a battery management system is used, the performance of the lithium battery pack will still get worse as the use time increases. Does this mean that the battery management system is actually not of much use to the lithium battery pack?

　　With this understanding, there seems to be nothing wrong with it at first glance. But we need to know that the battery management system of lithium battery UPS is actually just a protection function. If you want to solve the problem of performance degradation of lithium battery packs during use, you need to start with the overall design of the lithium battery pack and its component materials.

　　A simple management system cannot solve the performance degradation problem of lithium battery packs, but this does not mean that the battery management system is useless. Although the management system cannot solve the problem of performance degradation, it can effectively slow down this process, which can be regarded as extending the service life and safety performance of the lithium battery pack in disguise.

　　Battery Management System Definition

　　The battery management system is a system that manages batteries. It usually has the function of measuring battery voltage to prevent or avoid abnormal conditions such as battery over-discharge, over-charging, and over-temperature. With the development of technology, many functions have been gradually added. The object is usually a rechargeable secondary battery, and in recent years, it has mostly appeared together with a lithium-ion battery pack.

　　The role of battery management system

　　On the one hand, it detects, collects and preliminarily calculates the real-time status parameters of the battery, and controls the on and off of the power supply circuit based on the comparison between the detected values and the allowed values; on the other hand, it reports the collected key data to the controller and receives instructions from the controller. Work in coordination with other systems on the lithium battery UPS. Battery management system, different cell types often have different requirements for the management system.

　　Advantages of Battery Management Systems

　　safety

　　Protect single lithium batteries or lithium battery packs from the influence of external power and prevent safety accidents when using lithium batteries.

　　Durability

　　This allows the lithium battery to work in a reliable and safe area and extends the service life of the lithium battery.

　　Demand

　　Keep the lithium battery working in a state that meets the working requirements of the lithium battery UPS.

　　Nowadays, the commercial lithium batteries produced must be connected to the management system, so that the lithium batteries can be effectively controlled and managed, so that the lithium batteries can work under appropriate conditions, and the safety, durability and power of the lithium batteries can be fully guaranteed. .
