The future of new energy vehicles and battery management systems

China's new energy automobile industry started in the early 21st century, and it has only been developed for more than a decade. Due to people’s thirst for environmental protection and renewable energy, new energy vehicles have ushered in development opportunities. In the future, new energy vehicles will act as a challenger to invade the vast market that originally belonged to traditional fuel vehicles, and due to the needs of social development, this kind of market share infringement can be expected.

While looking forward to the rapid development of new energy vehicles, we must clearly realize that the development of technology is the basis for the development of the industry, and stable, efficient, safe, and reliable products are the embodiment of technology. We must know that the current domestic The new energy vehicle industry is not friendly. Frequent electric vehicle spontaneous combustion incidents and false cruising range have exposed the imperfections of the current domestic design, testing, and production standards for new energy battery packs and battery management systems.

At present, there are hundreds of BMS companies in China, while there are only a few in developed countries in Europe and the United States. Large new energy vehicle manufacturers either choose to develop their own battery management systems or use internationally competitive BMS manufacturers led by Germany, Japan, and the United States. In fact, there is no shortage of excellent BMS manufacturers in China. For example, Shenzhen Litongwei Electronic Technology Co., Ltd (LTW) mentioned in the article is a company with core competitiveness that focuses on product quality. Its BMS system has achieved mass production. , Has reached brand cooperation with many domestic electric vehicles, electric vehicles, and technology companies. The product quality is reliable and the technology is advanced. As a reliable BMS platform product, it is highly regarded by customers.

The lack of technical parameters and standards, and there is no authoritative organization to conduct authoritative testing of BMS produced by manufacturers. This is the current predicament of the domestic BMS market, resulting in the unevenness of BMS products, and it is difficult to promote them on a large scale. At the same time, many domestic automobile manufacturers and battery PAC companies have insufficient understanding of the importance of BMS, thinking that as long as each single battery cell can be connected, the operation of the vehicle can be guaranteed. In pursuit of low prices and in order to sign contracts, some bad BMS suppliers can only reduce BMS function indicators or castrate some functions altogether, thereby planting potential safety hazards. This is also irresponsible and harmful to the entire industry. Only by establishing a unified industry standard as soon as possible, suppressing manufacturers that do not meet market requirements, and establishing a sound inspection system, can battery management systems and new energy vehicles have a sustainable future. This is also the demand of many manufacturers and consumers.
