How do lithium-ion batteries plus manufacturers to achieve effective management of lithium-ion batteries? All major lithium-ion batteries are talking about how to implement battery effective management, battery life has always been a problem such as consumer electronics, and can build an efficient battery management system and it can affect a product of a product. How do lithium-ion batteries plus manufacturers to achieve effective management of lithium-ion batteries? Compared with other batteries, lithium-ion batteries, high performance, low pollution, long life, strong power, and are widely used in space aviation power equipment, electric vehicles, medical equipment and other categories. However, the bad operation of lithium-ion batteries not only reduces the performance of the battery, but also causes serious safety hazards, so develops safety, stability, and reliable battery management system BMS, which has very great practical meaning and practical value.

Lithium-ion battery protection circuit designs due to the chemical properties of lithium ion batteries, in the normal use process, their internal electrical energy and chemical energy is converted to each other, but under certain conditions, such as overcharge, over-discharge and Overcurrent will cause chemical side reactions in the battery inside, which will seriously affect the performance and service life of the battery, and may sprout a large amount of gas, so that the internal pressure of the battery is rapidly increased and causes safety problems. Therefore, all lithium-ion batteries must be protected for efficient monitoring of the charging and discharging state of the battery, and the discharge circuit is closed by alert to the lithium ion battery under certain conditions. Lithium-ion battery protection circuit includes excessive charging protection, overcurrent / short circuit protection and over-discharge protection, requires high precision, protection of IC power, high resistance, and zero-volt-chargeable characteristics.

Research and implementation of lithium-ion battery management system due to the constraint between the processing process of the lithium ion battery, there is an inconsistency between the lithium-ion battery monomers, even if there is also differences in the same batch. In addition, even if the battery pack is better than the factory, this inconsistency will increase with the number of cycles of the battery pack in the future. The function of the lithium-ion battery management system is getting stronger.

Lithium-ion battery management system is important by charging module, data acquisition module (including voltage, current, temperature data acquisition), equalization module, power calculation module, data display module, and storage communication module. Effective management and control of the battery management system ensures that the lithium-ion battery pack performance is good, extend battery pack life, protect battery safety, reduce operating costs, and plays a tight use of electric vehicles. Therefore, the research of BMS lithium-ion battery management system has a tight theoretical value and practical meaning.

How to make effective thermal control management of lithium-ion batteries? The exploration idea of ​​starting from the battery mechanism is to develop new electrode materials and media materials, using more efficient, stable materials for the processing and development of lithium-ion batteries, and ensure safe use of lithium-ion batteries from the source. However, the current research work is still not very good to meet the processing life. How to make safety optimization of lithium-ion batteries on the existing industrial basis becomes a focus.

At present, the mainstream lithium-ion battery heat pipe control method is important to the following: air cooling, liquid cooling, heat pipe cooling, phase change material cooling method. These four lithium-ion batteries have featured. The above is the effective management of lithium-ion batteries, and its chemical response is very complicated in the lithium-ion battery.

While people continue to improve the battery's own performance, they are also constantly researching the battery management technology and use. Add lithium-ion battery life, improve battery efficiency, maximize battery performance. .
