Passive and active safety systems are beginning to merge with other electronic systems in the car, and cars are becoming more autonomous and smarter. With the help of advanced driver assistance systems such as radar and visual inspection, electronic systems that respond much faster than drivers will take over control, reduce the frequency and severity of accidents, and dramatically improve the driving experience. This article refers to the address: http:// In recent years, automotive-related topics have always occupied a large size in the global media. One, in the current economic downturn, the global auto market is facing constant shocks; second, the world places too many expectations on new energy vehicles, and the topic of new energy vehicles always attracts widespread attention. For the big country China, which produces and manufactures automobiles, there is also the social topic brought about by the rapid growth of automobiles – the economic dividend brought about by the rapid growth of the automobile industry, and the resulting urban congestion, environmental pollution and traffic safety, etc. . The application of new technologies in automobiles is becoming the key to solving these problems. Traditional automakers hope to use innovative technology to seize the opportunities in the increasingly fierce market competition, and even the "outside" Google has quietly carried out experiments on hundreds of thousands of kilometers of driverless cars. New energy vehicles are seen as a panacea for solving the environmental problems and oil consumption difficulties brought about by the rapid growth of automobiles, and battery management and motor drive technology have become the key to the future of the new energy vehicle market. In addition, user needs and government regulations are driving the car to be more secure and smarter in 2012. Battery management technology is the key to new energy vehicles Battery technology is an important driver of new energy vehicles. At present, the batteries in new energy vehicles pose great challenges to the development of new energy vehicles, such as how to improve the charging time and service life of batteries, reduce the weight of batteries, increase the battery life, reduce costs, and ensure the use of batteries. Safety and other issues are urgently needed and must be solved by new energy vehicles. Recently, as the industry's accuracy requirements for battery power calculations continue to increase, and the emergence of more and more excellent battery technology, the battery charge and discharge curve is flatter. Therefore, the battery management chip needs 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. In addition, many manufacturers have begun to pay 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 current direction of ADI in the field of battery management chips. The solution of these problems means that a series of problems such as battery system safety, battery life and cost that consumers are worried about will be solved, which will speed up the popularization of new energy vehicles. Lead-acid battery control in new energy vehicles is a key part of improving energy efficiency. In this area, ADI has a market share of over 95% in the US and Europe. 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 and build safety monitoring devices for their safety environment. This new monitor gives designers the ultimate solution needed to develop a complete battery monitoring and protection system front end. The AD7280A/8280 is an integrated solution that monitors the voltage and temperature inputs of six battery cells, an enhanced daisy-chain interface, and the ability to flexibly match battery pack architectures with different battery counts. The device is powered by a battery pack and provides shared or separate alarms for any of three conditions: overvoltage, overtemperature, or undervoltage. In the motor control section, ADI's AD2S12xx family of resolver decoders offers angular resolution of 12 to 16 bits and tracking speeds of up to 3000 rpm, which are widely used in permanent magnet synchronous motor drives. For power management challenges, ADI is developing lithium-ion battery monitoring technology that includes all the features required for fast and accurate monitoring and safe control of lithium-ion battery packs used in hybrid electric vehicles. Unlike existing chip solutions, this new battery monitoring technology has a very comprehensive set of features, including voltage and temperature measurements, fault alarm output, and battery balancing capabilities, and has the highest specifications. This technology saves system cost by stacking devices in a high voltage environment without the need for multiple isolators. Design safer, smarter cars The "National Plan for the 12th Five-Year Plan for the Development of Road Transportation Industry" issued by China recently stipulates: during the "Twelfth Five-Year Plan" period, dangerous goods transport vehicles, international road transport vehicles, three or more types of line and tourist passenger vehicles, and emergency The installation rate of the satellite positioning system for the vehicle fleet is guaranteed to reach 100%.
