The BMS industry attracts a large number of battery manufacturers to join -Lithium - Ion Battery Equipment
The BMS (Battery Management System) industry has attracted a large number of lithium-ion battery manufacturers to join. With the continuous expansion of the power lithium battery and energy storage battery market, the BMS (battery management system) is an indispensable core component that carries the "brain and housekeeper" function in the lithium-ion battery pack. It can monitor the use status of the battery at all times. Necessary measures to mitigate battery pack inconsistencies. Therefore, there are more and more lithium-ion battery manufacturers deploying BMS battery management systems in the market.
What does BMS do?
As we all know, the BMS battery management system mainly appears in lithium-ion batteries. Lead-acid batteries generally do not have this management system. Lithium batteries need one more BMS battery management system than lead-acid batteries to protect the cells.
Regarding the functions of the BM battery management system S, there are different classification methods in the industry. However, from the user's point of view, it can be roughly divided into two major functions - "battery health check" and "safety guard".
●Instant physical examination to accurately grasp the battery status
Instant "health check", which refers to battery data collection and status assessment. Data acquisition can be simply understood as a routine "physical examination" for the battery; during the charging and discharging process, the terminal voltage, temperature, charging and discharging current and total voltage of each battery in the battery pack are collected in real time to prevent the battery from being overcharged or overdischarge phenomenon.(Lithium - Ion Battery Equipment)
This "physical examination" is online, continuous, and uninterrupted. When abnormal data is found during the process, the status of the corresponding battery can be queried in time, and the battery with the problem can be selected, so as to maintain the reliability and high efficiency of the entire battery pack.
● "Safety Guard" to protect battery and personal safety
Another core function of BMS is "safety guard". In fact, it is the purpose of protection, which includes the self-protection of the battery and the protection of personal safety.
As we all know, overcharging and overdischarging of the battery will cause local overheating, not to mention affecting the battery life, and in severe cases, it will threaten the safety of the battery pack and cause personal safety hazards. At this time, the "charge and discharge management" module of the BMS starts the protection function. On the one hand, it communicates with the vehicle and the charger. Let happen.
The BMS (Battery Management System) industry attracts a large number of lithium-ion battery manufacturers to join
The key purpose of BMS (Battery Management System) is to enhance the utilization efficiency of the battery, prevent excessive charging and excessive discharge of the battery, increase the service life of the lithium-ion battery, and monitor the state of the lithium-ion battery. In layman's terms, it is an operating system for managing, controlling, and using lithium-ion battery packs. The BMS industry belongs to the midstream industry of the power lithium-ion battery industry chain. The BMS industry chain includes four links: mid-upstream raw materials, BMS modules, BMS finished products, and downstream applications.
The BMS is like the brain of the battery, sending and receiving information from the battery and each external port, after in-depth analysis and processing of the information, and sending out work orders. Considering that it has a crucial impact on new energy vehicles, the BMS industry continues to attract a large number of lithium-ion battery manufacturers to join.
my country's power lithium battery PACK and BMS (battery management system) manufacturers are mainly divided into three categories: battery companies, car companies, and third-party independent or joint venture professional PACK and BMS companies. The business model is also divided into three categories: concurrently doing PACK and BMS BMS, only do PACK, only produce BMS.
Compared with consumer and energy storage battery BMS, power lithium battery BMS has greater room for growth and market size; under the background of "safety + high energy", power lithium battery BMS will receive more and more attention from the industry chain and will continue to grow. With rapid development, power lithium battery BMS will also have higher profit margins and become a field of competition for many BMS companies.
Automakers in mainland my country, such as Beijing Changan, BAIC Motor, Geely Automobile, etc., all have professional R&D departments to carry out BMS research and development. In addition to the control of core technologies, they are more competitive than other companies in terms of cost and efficiency.
So far, the top three power lithium battery companies in mainland my country have all entered, and most of them are in the "BMS+PACK" mode. They have mastered the entire set of core technologies from power lithium battery cells to battery packs, and have relatively strong competitive strength. Representative companies include BYD, CATL, AVIC Lithium Battery, Guoxuan, etc.
An important domestic BMS battery management system manufacturer
1. BYD
The electric vehicle of BYD Co., Ltd. is equipped with its own battery and battery management system. Taking BYD Qin as an example, its battery management system not only has the basic functions of battery energy management and battery thermal management, but also has the function of automatic balancing of battery cells. During the operation of the whole vehicle, the single performance parameters of the entire battery pack are monitored, and the purpose of timely and automatic maintenance is achieved through the battery equalization function, which greatly reduces the time cost of power lithium battery maintenance, prolongs the service life of the battery, and improves various stage performance.
2. CATL
Ningde Times has always aimed to be the world's safest battery as its development goal, and is the first battery company in the industry to enter the field of functional safety and at the same time the most complete.
Throughout the platform development process, BMS strictly abides by and meets the international standard ISO26262, and has rich experience in related projects. It has successively carried out functional safety management and development in BMW, Volkswagen and PSA projects; It has been recognized by more domestic and foreign OEMs.
Summarize:
A battery management system turns a bunch of "dumb" cells into a smart battery pack. As an electronic component for real-time monitoring, automatic balancing, and intelligent charging and discharging, the battery management system (BMS) plays important functions such as ensuring safety, prolonging life, and estimating remaining power. "A battery pack without battery management is a bomb." The battery management system importance is evident.
