With the strong support of the state and the strengthening of people's awareness of environmental protection, consumers gradually realized the advantages of new energy vehicles. In 2014, the domestic electric vehicle market grew rapidly, and the sales share was 320% in 2013. It can be predicted that domestic new energy vehicles will continue to flourish in the next few years.
Xu Zhibin, Marketing Manager of Greater China, Automotive Electronics Division of Analog Devices, said in an interview that in the past year, ADI has made great achievements in the fields of automotive safety, predictive safety, in-vehicle infotainment, and new energy vehicles. . Especially for new energy vehicles, ADI is the first in the industry in the field of traditional 12V lead-acid battery management, with a market share of over 95% in the world. Lead-acid batteries are used more in the start-stop function, which relatively improves the fuel efficiency of conventional vehicles. In addition to lead-acid batteries, ADI has also introduced a range of lithium battery monitoring and protection systems for hybrid and pure electric vehicles. The system integrates a lithium battery safety monitor to help users implement fail-safe circuits. A security monitoring device for a secure environment. This monitor provides designers with the ultimate solution needed to develop a complete battery monitoring and protection system front end.

The reason why ADI has achieved such great achievements in the field of automotive electronics is because ADI pays attention to the early exchange and cooperation with the yard, and gives reasonable and effective solutions according to the needs of the car manufacturers, especially in the field of electric vehicles. ADI and the famous European and American car manufacturers have deep cooperation in lithium battery management, such as cooperating with some domestic car manufacturers to make system recommendations in the field of 24V/48V, and developing customized products for the car manufacturers.
Xu Zhibin, Marketing Manager, Greater China, Automotive Electronics Division, Analog Devices, said that in the traditional 12V lead-acid battery management field, ADI is in the first place in the industry, accounting for more than 95% of the global market share.
In the field of power management, as the industry's accuracy requirements for battery power calculations continue to increase, more and more excellent battery technology emerges, resulting in a flatter battery charge and discharge curve, so battery management chips need to have higher measurement accuracy. . In addition, due to the failure characteristics of lithium batteries, the reliability and safety of battery management systems are critical. Domestic manufacturers have begun to pay attention to system-level security design and the introduction of the ISO26262 standard. In the field of battery management chips, mainstream semiconductor manufacturers have integrated more and more fault reporting mechanisms, data verification mechanisms, and redundancy monitoring mechanisms in their chips to help customers achieve higher levels of system-level security. These new technology trends are also the direction that ADI is working on in the field of battery management chips.
Incentives are constantly being introduced, hybrids and electric vehicles will receive more and more attention from society and consumers. The lithium battery technology of hybrid vehicles and electric vehicles will inevitably break through. How to effectively monitor the use of lithium batteries, and Protecting the car's operating system becomes very important. When talking about the planning of ADI in the field of electric vehicles in 2015, Xu Zhibin said: "The lithium battery management and isolation chip has been developed for this application ADI. In addition, driven by various policies and regulations, the entire automotive industry The chain will increase the emphasis on fuel economy and emissions reduction, and ADI's sensor and sensor interface products and solutions in powertrains will be of great use."
The technological innovation of semiconductor manufacturers is an indispensable driving force for the development of new energy vehicles. As far as the future development of China's new energy vehicles is concerned, cooperation between OEMs and automotive electronics solutions providers will be a major trend. In the future, cooperation between OEMs and automotive electronics solution providers will be closer, which will be reflected in the increase in the level and dimension of cooperation. ADI is deeply rooted in the Chinese market, working hard from the entire industry chain, working with many battery management vendors to serve parts suppliers and yards.
