What is BMS system? Battery Management System BMS Market Outlook. China's new energy vehicle industry is growing explosively and has become the world's largest market in terms of production and sales. The rapid expansion of the new energy vehicle market has brought significant opportunities for the battery management system BMS industry, which, as an important link between the power battery and the new energy vehicle, is vital to the good operation of the vehicle system.
What is BMS system?
BMS has an important role in real-time monitoring of battery status information, analyzing battery safety performance, optimizing battery energy control and extending battery life, which has a great impact on the safe operation, charging mode and driving cost of new energy vehicles. With the increasing attention to the range of new energy vehicles and battery safety, BMS technology has been rapidly developed and the market scale has been expanding.
The BMS system refers to the battery management system, which is a system for managing the battery. The BMS is mainly designed to intelligently manage and maintain each battery cell, prevent the battery from overcharging and over-discharging, prolong the life of the battery, and monitor the status of the battery.
According to the management structure of BMS, BMS can be divided into centralized management system, semi-distributed management system and distributed management system. Centralized management system architecture is relatively simple and suitable for smaller battery packs, distributed is more suitable for large battery packs, complex structure and higher cost, but safety and accuracy have better performance, while semi-distributed is a compromise between the two, the advantages and disadvantages are not particularly obvious.
Battery management system BMS as real-time monitoring, automatic equalization, intelligent charging and discharging electronic components, to ensure safety, extend the life, estimate the remaining power and other important functions, is an indispensable and important part of the power and energy storage battery pack, it through a series of management and control, to ensure the normal operation of electric vehicles.
Battery Management System BMS Market Prospects
With the accelerated expansion of power battery enterprises and the rapid increase of new energy vehicle ownership, the importance of BMS is becoming more and more prominent, and the core position of BMS in ensuring the safety and life of power batteries is increasingly recognized. With the three major functions of battery monitoring, SOC evaluation and voltage equalization, BMS has an irreplaceable core position in guaranteeing power battery safety and improving battery life, which brings significant benefits to various downstream industries of new energy vehicles.
As the manager of the car power battery, BMS has all the data of the power system when the vehicle is running, and these data are of great value for improving the car power system and even the performance of the whole car, thus occupying a high value of the battery industry chain.
The price of the battery management system BMS is positively correlated with the number of cells in the battery pack, and the battery management system BMS occupies 30% of the total cost of the battery pack. Considering that the circuit board and chip design of BMS is still in the primary stage, while the complexity of the later products, the speed of renewal and mass production scale will gradually increase, therefore, it is expected that the mainstream battery management system BMS price will show a slow downward trend, which can be reduced to about 60% of the current one in 2020.
At present, the cost of the battery system occupies a high cost of the vehicle, and BMS cost occupies 20% of the cost of the battery system, so it is important to reduce the cost of BMS to reduce the cost of the battery system, through the device, platform generalization and other technical design can reduce development costs, while the scale of production can effectively reduce costs. The market size of domestic BMS for new energy vehicles is expected to reach about 8.5 billion yuan by 2020, with a compound annual average growth rate of 29%.
With the increase in the release of new energy vehicles, the future BMS market will accelerate the explosion, through the BMS R & D testing, manufacturing, secondary use and battery data and other aspects of the enterprise will be more competitive. Establishing unified industry standards, improving BMS product quality, and reducing production costs and prices are the key issues in the domestic BMS field, and the increase in market concentration will help accelerate the solution of these issues and promote the high-speed and healthy development of BMS and new energy vehicle industry.
