BMS is usually called the brain of the power lithium battery system of electric vehicles. Together with the power lithium battery and the vehicle control system, BMS forms the three core technologies of electric vehicles. BMS can improve the utilization rate of the battery, prevent the battery from overcharging and over discharging, and extend the service life of the battery. In addition, BMS can also monitor the status of batteries and vehicles to ensure the performance and safety of electric vehicles.

Although it plays an important role in electric vehicles, the development of domestic BMS industry is not satisfactory. With the development of new energy vehicles, BMS is expected to rise rapidly, with huge market space.

What is the future development trend of BMS? How should BMS operate? What else does BMS need? Xu Wenfu, general manager of Blue Microelectronics, had in-depth exchanges on the development of the domestic BMS industry.

Q: In recent years, the development of blue microelectronics is very rapid. As a company specializing in the R&D, production and sales of BMS, what do you think is the secret of the success of Blue Microelectronics, and what relevant experience can be used for reference by other BMS companies?

Xu Wenfu: Founded in October 2002, Blue Microelectronics is a subsidiary of Desai Battery. So far this year, our company has nearly 2000 employees, occupying a relatively high market share in the world. Last year's turnover also reached 2.397 billion yuan. In the ten years since its establishment, I think we have done three things right.

First of all, we have always insisted on ensuring product quality, which is our fundamental way of survival. In order to achieve this, we have made a lot of efforts in internal management, laying a foundation for the quality of our products.

Secondly, we have done a good job in customer service, especially in our dealings with foreign customers. The customers of Blue Microelectronics include many international well-known companies. It is particularly important to maintain foreign customers when the profit space of the domestic market is further compressed. With the rapid growth of global electric vehicles, the demand for batteries is unstoppable. Navigant Research, a consulting firm, pointed out that the global market size of lithium-ion batteries for passenger vehicles was US $3.2 billion in 2013 and will reach US $24.1 billion in 2023. On the other hand, no matter the technology itself, or out of prudent consideration, or just psychological factors, auto companies are often more willing to choose foreign battery suppliers, especially battery manufacturers that have experience in carrying batteries on overseas models. LG Chem is a typical example. Although the Chevrolet Volanda equipped with LG chemical batteries had a fire accident in 2011, it has been calm in recent years, and the sales of Volanda are also gradually increasing, ranking top in the global electric vehicle sales list. With the success of Volanda, LG Chem has further consolidated its position in the field of automotive batteries and gradually extended its tentacles to the world, including China.
