AG8 battery.my country's installed capacity of power lithium battery BMS products reaches 1.22 million units

　　Driven by the rapid development of the domestic new energy vehicle market in the past two years, the domestic power battery BMS market demand has also grown rapidly. In 2017, my country's new energy vehicle power lithium batteries achieved an installed capacity of 811,000 units, a year-on-year increase of 56.26%, with a market size of 4.55 billion yuan. Data from the Advanced Industry Research Electric Vehicle Institute (GGII) shows: my country's new energy vehicle power lithium batteries in 2018 The installed capacity of battery BMS products reached 1.22 million units, with an output value of 5.5 billion yuan.

　　Judging from the competitive landscape of my country's BMS market, the current third-party market share has shown a steady increase in market share. Third parties represented by Kelie Technology, Yineng Electronics, Ligao New Energy, Shanghai Miaoyi, etc. are steadily increasing in market share. Growth, especially in the commercial vehicle segment, where third parties are even becoming dominant. Although vehicle manufacturers and battery manufacturers still occupy a relatively important position, the advantages of professional third parties are expected to become more prominent in the future, driven by cost reductions brought about by technological improvements and specialized division of labor in the industry.

　　From the perspective of industry technology trends, the balance control of BMS is one of the technical commanding heights for extending the life of power batteries. Currently, passive balancing appears earlier and the technology is relatively mature, and passive balancing has less impact on battery life and has lower costs. In line with the current market situation in which my country's new energy vehicles are mainly concentrated in the mid- to low-end, car companies generally adopt a passive equilibrium. However, since passive equalization uses resistors to consume energy, heat will be generated, reducing the efficiency of the entire battery system. The principle of active balancing lies in the transmission and distribution of energy, which can make the energy utilization rate of the power battery high and significantly improve the driving experience. Against the backdrop of my country's accelerating upgrading of new energy vehicles and companies' increased emphasis on product safety, active balancing is expected to become the main technical direction for the future balancing function of my country's BMS.
