New energy vehicles have promising prospects, but electronic control and BMS are obstacles?

　　New energy vehicles are a strategic emerging industry of the country and are currently in a very critical market growth period. In 2018, against the background of the general downturn in the passenger car market, the new energy vehicle market experienced major events such as the reduction of subsidies and the official introduction of the dual-point policy. Sales are still rising and developing well. It is obvious that domestic new energy vehicles are currently in a market growth period. According to data released by the Passenger Car Association, in 2018 new energy passenger vehicles (pure electric vehicles and plug-in hybrid vehicles with a driving range of more than or equal to 50 kilometers in pure electric mode) ) wholesale volume reached 1.008 million units, a year-on-year increase of 88.5%. Both the total volume and growth rate achieved breakthroughs again compared with 2017. It can be seen that new energy vehicles have developed to a considerable scale, but as an emerging industry, new energy vehicles still cannot escape the laws of technological development. The core of electric vehicles is the battery, and the core of the battery is the battery management system (BMS). BMS is an indispensable component in the power and energy storage battery pack. It ensures the normal operation of electric vehicles through a series of management and control. Over the years, power electronic control in new energy vehicles has faced reliability and safety challenges. The measurement accuracy of the battery management system is also a challenge in the future, including battery system voltage, current, system insulation, SOC, SOH, Detection accuracy of system parameters such as SOP. In response to issues related to battery safety and reliability, many companies are now launching power supply warranty policies, such as NIO ES8’s terminal policy: after 1,200 full charges, the battery will be replaced free of charge if the attenuation exceeds 20%. Warranty policies can naturally help dispel consumer concerns, but if companies want to achieve low cost and high quality, battery management and control is still a difficult problem in the new energy vehicle market. Technologies such as power electronic control and BMS will undoubtedly become the key issues in the new energy vehicle market. In terms of technological competition, the industry is in urgent need of cost-effective and breakthrough technologies to promote development. In order to jointly explore higher quality and high-efficiency power control technology, the 6th (Shenzhen) New Energy Vehicle Electronic Control and BMS Technology Seminar will be held at Shenzhen Dunhill International Hotel on April 26, 2019. This meeting will focus on Many topics such as active and passive safety technology of new energy vehicles, electric drive technology solutions for new energy vehicles, BMS safety and reliability of new energy vehicles, and new energy charging pile technology solutions will be held. Well-known experts and scholars from major companies will be invited to give speeches. . The conference has been successfully held for five times. This conference will continue the tradition of previous conferences, bringing together many well-known experts, scholars and top solution providers to share the latest practical applications of the three most critical technologies of new energy vehicles: battery, electric and electronic control. Cases to solve key problems in product development. This conference will usher in the latest similar technical solutions, help the industry further in-depth exchanges, help manufacturers master the latest technology, expand their competitive advantages, and prepare for the research and development of breakthrough new products in 2019. In addition to technical exchanges, there are dozens of display companies competing on the same stage to help companies better complete product selection. At the same time, the organizer also has an address book of thousands of people in the automotive industry, as well as various automotive industry alliances and WeChat groups, providing good opportunities for communication and cooperation for the entire industry chain ecosystem, and helping companies achieve product innovation, model innovation, and business development and expansion. .
