With the global awareness of environmental protection and the concept of green development, the development of new energy vehicles has become a long-term strategic goal of many auto manufacturers. At the 66th Frankfurt Motor Show, which opened on September 18th this year, German automotive experts gave a speech on the problems facing the development of new energy vehicles. At the same time, the German Chancellor promised to promote the orderly development of electric vehicles from the government level as soon as possible. . In recent years, major automobile brands have been launching electric vehicles. The development speed of new energy vehicles has gradually slowed down. It can be seen that the development of new energy vehicles is still facing severe challenges.

Duden Huff, an expert in the German automotive industry, cited the reasons for the stagnation of the three-point electric vehicle industry. One is higher than the price of the fuel car, the second is the battery life problem, and the third is the problem of the car charging facility. In this regard, Mr. Wang Xingyu, senior system engineer in China, Automotive Electronics Market Division, Analog Devices, a leading global provider of high-performance signal processing solutions, said: "There are several factors that have constrained the development of new energy automotive electronics in China. First, at present. There are not many products with independent intellectual property rights in China. At the same time, foreign auto parts companies apply for patents in China and use patent technology to dominate the Chinese automotive electronics market. Secondly, batteries in new energy vehicles are also a big challenge. How to improve the battery Charging time, service life, reducing the weight of the battery, increasing the battery life, etc., are all urgently needed and must be solved by new energy vehicles."

Recently, as the industry's accuracy requirements for battery power calculations continue to increase, more and more excellent battery technology has emerged, resulting in a flatter battery charge and discharge curve, so battery management chips need to have higher measurement accuracy. Wang Xingyu strongly agrees with this point: "In the field of battery management chips, mainstream semiconductor manufacturers have integrated more and more fault reporting mechanisms, data verification mechanisms, and redundant monitoring mechanisms in the chip to help customers achieve higher levels. System-level security. Finally, many vendors are paying attention to more efficient active battery balancing to reduce the heat of the battery management module and save power consumption. These new technology trends are also the focus of ADI in the field of battery management chips. direction."
"For the power issue of new energy vehicles, ADI promotes the chip for lead-acid battery control (ADuC703X)." Wang Xingyu continued, "In this field, ADI has more than 95% market share in Europe and America. Lead-acid batteries are more It is used in the start-stop function to improve the fuel efficiency of traditional vehicles. In addition to lead-acid batteries, ADI has also launched a series of lithium battery monitoring and protection systems that can be applied to hybrid vehicles and pure electric vehicles. The product, the system integrates a lithium battery safety monitor, which can help users implement fail-safe circuits and build safety monitoring devices for their safety environment."
The development of new energy vehicles has a bright future in the current market environment, and more applications and products related to new energy vehicles will be introduced to the market. As a leading supplier in this field, ADI has been actively working to meet the needs of consumers and is committed to technological innovation in the field of new energy vehicle batteries.
