Based on the R&D, design and intelligent manufacturing capabilities of the new energy battery intelligent management system (BMS), Foxtheon Energy has developed and produced many new energy lithium battery products, hoping to make low-carbon energy benefit every family and industrial and commercial users.

Today, the editor will popularize some basic knowledge of lithium battery BMS for you.

What is lithium battery BMS? Why do you need a BMS lithium battery management system? When it comes to lithium batteries, it is often connected to some terms such as lithium battery protection boards and lithium battery management systems. As we all know, BMS battery management system mainly appears in lithium batteries, lead-acid batteries generally do not have this management system, lithium batteries need more BMS battery management system than lead-acid batteries to protect the cells.

What is lithium battery BMS?

BMS battery management system is the link between the battery and the user, the main object is the secondary battery, the function is to improve the utilization rate of the battery, prevent the battery from overcharging and overdischarging, increase the service life of the battery, and supervise the state of the battery. In layman's terms, it is a set of operating systems for managing, controlling and using lithium battery packs.

The BMS industry belongs to the midstream industry of the power lithium battery industry chain. The BMS industry chain includes four links: middle and upstream raw materials, BMS modules, BMS finished products, and downstream applications.

BMS is called the "brain" of the power battery operating system, BMS is like the brain of the lithium battery, sending and receiving the information of the battery and each external port, in-depth analysis and processing of information, and transmitting out the execution of work orders. Considering the crucial impact on new energy vehicles, the BMS industry continues to attract large-scale lithium battery manufacturers to join.

Why do you need a BMS lithium battery management system?

Lithium batteries are widely used in long-term standby remote monitoring instruments because of their high working voltage, small size, light weight, high energy density, no memory effect, no pollution, small self-discharge and long cycle life. However, lithium batteries also have some of their own defects, which can be summarized in the following two aspects:

(1) Security

Lithium-ion batteries have poor safety and have defects such as explosions. In particular, lithium-ion batteries with lithium cobalt oxide as the cathode material cannot be discharged under high currents and have poor safety. In addition, almost all lithium-ion batteries overcharge or overdischarge will cause some damage to the battery.

Lithium-ion batteries are also sensitive to temperature: if the use temperature is too high, it may cause electrolyte decomposition, combustion and even explosion; If the temperature is too low, the performance of the lithium-ion battery will deteriorate significantly, affecting the normal use of the equipment.

Due to the limitations of the lithium battery manufacturing process, the internal resistance and capacity of each battery will be different. When multiple lithium batteries are used in series, the charge and discharge rate of each battery is inconsistent, resulting in low battery capacity utilization. In view of this, in the actual use of lithium batteries, a special protection system to monitor the health of the battery, so as to manage the use of lithium-ion batteries.

(2) Maintainability

At low temperatures, capacity decay and power cannot be accurately predicted, which makes the equipment less maintainable. Long-term online instruments are replaced regularly, while remote monitoring equipment works in scattered locations, and the distance between each location is long, so the workload and cost of replacing batteries are large.

In order to reduce the maintenance workload and reduce the maintenance cost, the lithium battery management system should have an accurate power state estimation function, accurately grasp the power status of the lithium battery, and carry out battery replacement work in a more targeted manner. At the same time, the lithium battery management system should have lower power consumption to reduce the maintenance frequency and extend the battery life. Therefore, the reasonable design of lithium battery management system is of great significance for the maintenance of remote monitoring instruments with long-term continuous power supply.
