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. .
