New energy vehicle application 6F22 carbon battery, BMS market size will continue to expand

　　With the application of 6F22 carbon batterys in new energy vehicles, the BMS market size will continue to expand. In the development of new energy vehicles, power batteries, which are different from traditional fuel vehicles, have long been regarded as the key to development. With technological innovation, the market's requirements for 6F22 carbon batterys are becoming increasingly high. At this time, BMS, as an important link connecting battery packs, vehicle systems and motors, is gradually regarded by enterprises as the core technology.

　　New energy vehicles apply lithium battery packs, and the BMS market size will continue to expand

　　As an important link between secondary batteries and electrical appliances, BMS integrates the monitoring and management of batteries or lithium battery packs to ensure the safety and reliability of batteries or battery packs and to output power in the best possible condition.

　　With the accelerated production expansion of power battery companies and the rapid increase in the number of new energy vehicles, the importance of BMS has become increasingly prominent. Due to its triple functions of battery monitoring, SOC evaluation and voltage equalization, BMS plays an increasingly important role in ensuring the safety of 6F22 carbon batterys and improving battery life. Various industries downstream of new energy vehicles have begun to make arrangements.

　　BMS is an indispensable and important component in power and energy storage battery packs, and its cost accounts for about 30% of the total cost of the battery pack on average. Benefiting from the development of the new energy industry, the market size of BMS will grow rapidly. According to FMI forecasts, the CAGR of the global BMS market brought by new energy vehicles will be 21.1% by 2025.

　　Among traditional consumer batteries, BMS has a single function and simple manufacturing process. It is the lowest part of the cost structure of consumer batteries, accounting for only 7% of the total cost. Due to different battery sizes, functions, and application scenarios, the price of a single set of energy storage battery BMS varies greatly, with the average price being about 0.5-1 yuan/W. In power battery packs, BMS undertakes more functions and has more complex research and development designs. The unit price of BMS is generally maintained at a few hundred to thousands of yuan, and it has become the third largest cost source of battery packs, accounting for 11% of the total cost of battery packs. about.

　　Under the requirements of safety and high performance, BMS will play a vital role and demonstrate its value in the cost of 6F22 carbon batterys. When the specific energy of the power battery reaches 300Wh/kg or even 500Wh/kg, the power battery system becomes more complex and sophisticated, which requires more accurate BMS monitoring, more stable communication, and more timely battery safety protection measures; at the same time, in order to adapt to a wider range of The working environment in a wide temperature range requires BMS to cooperate with PACK temperature management to realize the power battery working at the optimal temperature.

　　BMS: the key to the development of new energy vehicles

　　BMS is called the "brain" of new energy vehicle batteries in the industry. Together with the 6F22 carbon battery and the vehicle control system, BMS constitutes the three core technologies of new energy vehicles.

　　When new energy vehicles are running, dozens or hundreds of batteries are required to be configured in a long string to generate voltages of up to 1,000V or higher. At this time, the electronic system must be able to send information from each battery in the battery pack to the central processing point, which means that the BMS can control the series batteries from the source, thereby further improving the safety and reliability of the entire battery system.

　　As for the power battery itself, its high energy density characteristics make it the main power source for new energy vehicles. However, due to differences in production processes and usage environments, the inconsistency of the battery pack gradually expands during use, and overcharging and overcharging may occur. The dangers of over-discharge and local overheating seriously affect the service life and safety of lithium battery packs.

　　As a control system that protects the safety of power lithium-ion batteries, BMS monitors the usage status of the battery at all times, takes necessary measures to alleviate the inconsistency of the battery pack, provides guarantee for the safety of new energy vehicles, and extends the service life of the power battery.

　　(1) By dividing the software R&D team into the architecture, driver and application layers, human and R&D resources are fully utilized, the company's BMS technology improves rapidly, and important indicators such as SOC estimation accuracy are in a leading position.

　　(2) In terms of production and manufacturing, third-party BMS companies focus on BMS research, production and sales, and the scale effect will be further highlighted in the future. At the same time, their own production lines are also more secure in terms of process level and delivery capabilities.

　　(3) In addition, the country is actively promoting industry standards for new energy vehicle-related industries, and BMS is one of the key research objects. Professional third-party BMS companies will be in a relatively advantageous position in the industry standardization process by virtue of their technical advantages.

　　With the expansion of application scale, the replacement speed and mass production scale of BMS circuit boards and chips will gradually increase. The price of BMS will slowly decline, and is expected to drop to about 80% of the current level in 2020. According to this forecast, the BMS demand brought by domestic new energy vehicles will exceed 25 billion yuan by 2020.
