New Industry Research Institute through the market research, 2017 -2020 China's new energy automotive industry trends to make the following ten forecasts:
Trend 1: New energy vehicles will be more comprehensive indicators than the traditional fuel vehicles. With the power lithium battery, BMS, charging pile and other technical progress, the new energy vehicle mileage performance indicators gradually close to the traditional fuel vehicles, car comfort and technology content will be more than traditional new energy vehicles. War new research and development forecast, the latest indicators of new energy vehicles by 2020 will exceed the traditional fuel vehicles, 2018 will have more than a comprehensive model of more than traditional fuel vehicles.
Trend 2: the problem of insufficient charging pile is effectively solved. 2016 to 2020 new charging pile will gradually meet the new energy vehicle charging needs, including charging pile will become the new residential and commercial body of the standard, while fast charging technology will be rapid development, 30 minutes fast charge technology began to spread, The overall charging time will be shortened to the current one-third.
Trend 3: the current deduction of subsidies, 2017 new energy vehicle sales price as a whole is still higher than the traditional car, in 2020 more than the application of traditional cars will be close to the same or even lower than the traditional car.
Trend 4: pure electric new energy car mileage problem has been initially resolved, more than 300 km mileage will become the standard for new energy vehicles, high-end new energy vehicles mileage will be more than 600 km. 2020, pure electric car sales accounted for more than 20% is expected. 2030, pure electric vehicles become the mainstream of new energy vehicles, accounting for more than 80%.
Trend 5: 45 years of age consumers will focus on car purchase new energy vehicles. After the development of 2014 to 2020, consumers of new energy vehicles recognized a substantial increase in recognition, especially under the age of 45 consumers, new energy vehicles will be the focus of their purchase of cars to consider the model.
Trend 6: unmanned new energy vehicles began on the road. In 2020, there will be unmanned vehicles into the ordinary consumers, China's unmanned vehicles began to try on the road, the state will consider the development of unmanned vehicles standards, the future road construction will also consider the possible needs of unmanned vehicles.
Trend 7: the new energy automotive industry has undergone major changes in the pattern, there are more than five large-scale production and sales of new energy vehicles brand, in 2020, the national automobile manufacturing base more dispersed than in 2016.
Trend 8: the difficulty of production of new energy vehicles to reduce the assembly more convenient, industry competition. In 2020, the competition between new energy car companies is branded, performance diversification, intelligent development, especially the appearance and size of the car design more flexible, may be a new revolutionary change.
Trend 9: China's own brand began to large-scale internationalization, domestic enterprises began to international car prices mergers and acquisitions tide, China in the automotive field, especially in the field of new energy vehicles, the global influence has been improved and consolidated.
Trend 10: After 2020, the subsidy policy is expected to continue, new energy vehicles will enter the rapid replacement of traditional fuel vehicles, the fastest new energy vehicles in 2025 will exceed 10 million.
All the above trends have proved that in just a few years between the new energy vehicle market prospects are very optimistic, and used in electric vehicles in the semiconductor, especially lithium battery protection and BMS is particularly important, Silver Wing can share with you the following two Experience:
1、 for the product design multiple protection system. Taking BMS (battery management system) as an example, the end product function is becoming more and more complicated, the master MCU "pressure" is increasing, the additional software and stored data are more and more, leading to a significant increase in product failure rate, so need to set more The protection system protects the safety of the product. Advanced semiconductor companies can provide BMS with a protection IC completely independent of the secondary protection IC system, to achieve a fully dual configuration, enhance the protection system performance to further enhance product safety.
2、strengthen the product's anti-interference ability. Professional semiconductor company's secondary protection IC with self-test function, allowing users to understand the battery before the battery to work to protect the working state, to avoid the risk of protection system failure. In addition, also added a lot of security measures, hoping to reduce the failure rate for the electric car company to bring the most secure and reliable lithium battery safety protection system.
In addition to lithium batteries as energy new energy vehicles, the other hot is the use of super capacitors as a power source of new energy vehicles, which are generally used for larger public transport, such as electric buses, etc., due to the characteristics of the super capacitor semiconductor companies Of the products with two for overcharge protection and battery balance control two important features.
In the lithium battery protection IC and secondary protection IC, Seiko Semiconductor has more than 20 years of design and manufacturing experience, as Japan's first generation of lithium battery protection IC manufacturers, not only comprehensively enhance the safety performance of lithium batteries, more strengthened Product design protection and anti-jamming capability.
For the huge capacity of the super capacitor EDLC, it is stored in the power, can be used as a battery on the car motor, the car in the case of red light brake, it can use the idle motor to charge their own, until the car again, then the storage Of the power for other small car equipment used.
Similar to the super capacitor This green environment-friendly power IC, Seiko Semiconductor's dedicated development for the EDLC with overcharge protection and battery cell balance with the car battery protection IC S-19190.
Finally can not mention is Seiko semiconductor car IC, car Hall IC, mainly for magnetic field testing, such as car motors, windows, wipers and other location detection. In the clock chip, we have a real-time clock chip (RTC) for recording absolute time and a clock IC for recording relative time, and the latter has been widely used in the automotive field. Also used to heat the car in a small CPU operating procedures for automotive EEPROM. Each car inside the need to carry dozens of small CPU, in the Japanese market is the need for external EEPROM, so in the Japanese automotive equipment industry, Seiko Semiconductor's market share as high as 80% or more, ranked first, the global market share Second place.
