The car charger and traction inverter have been gradually realized
The car will find its own parking place, and then automatically charge. In addition, they will also be equipped with a rich vehicle communication and entertainment options. Passengers no longer need to own a car, through the lease or smart phone booking can easily meet travel needs.
The vision of the future is currently in its infancy, and the key to the realization of this vision is a matter of time and the need for support from the public according to market research firm IHS Automotive predicts that by 2025, electric vehicles (EV) and hybrid electric vehicles (HEV) sales will account for 1/4 of the global total car sales.
With the continuous changes in the way of transportation, TI (TI) has been committed to promoting the car towards greener, safer and more reliable aspects of the forward. TI technology can help HEV reduce greenhouse gas emissions, and zero emission of pure electric vehicles also hatch a new automated business model. Today's full hybrid cars can reduce fuel consumption by half, while plug-in hybrid vehicles can reduce fuel consumption by 80%.
At present, new cars contains more than 6000 semiconductor, and this data will continue to increase, because the car is becoming more and more intelligent, automotive parts such as battery management, traction inverter, car charger and DC/DC converter etc. more and more also gradually realize electronic.
TI's engineers have been behind the scenes to help the development of the trend from the car infotainment system and power management system, to the connectivity and advanced driver assistance systems (ADAS), a new semiconductor components they are developed which are running. In fact, some car manufacturers already have a large number of their own car sharing model, and for example, Google, Lyft, Tesla and excellent step and so on all major OEM manufacturers are developing unmanned vehicles. Driverless trucks have been on the road in the United States, Europe and australia.
Back To The Future: The Game
So far, HEV is more popular with consumers than EV, which may be due to the fact that although EV is greener, the cost is relatively high, and the overall performance of the gasoline engine can not be played out. However, at the recent Paris auto show, almost all car manufacturers have introduced a new electric or hybrid models. Pure electric vehicles to promote a large area still needs time. It is for this reason, TI will focus on the transition stage of HEV innovation, as well as the full electronic vehicle powertrain. HEV has brought fuel efficiency and automation, but the battery is currently being used by the recharge and mileage limit. In HEV, TI is developing high technology, including battery management, sensors and advanced monitoring, and 12V dual power rail and an extra high power consumption for the application of the 48V fuel battery, guide, and cost efficiency in order to achieve better.
Due to the low mileage range and longer charging time, the popularity of consumer EV outside the city area has been limited. One solution is to increase the battery voltage to 800V, so you can reduce the charging time to 20 minutes (up to 80%), the distance can reach more than 300 miles.
Automatic driving
By monitoring traffic, switching signals and communication between vehicles, the integrated circuit can make the car more autonomous. TI sensor has been applied to the driver assistance and autonomous parking system, the ultimate goal is to create a fully automatic driving car. Compared with most of the drivers, the car can achieve higher fuel efficiency, especially in the need to maintain a constant speed of the urban environment. At the recent Paris auto show, industry experts also claimed that the safety of the vehicle is higher, and can significantly reduce the number of traffic accidents, reduce casualties.
By 2020, most car manufacturers will be able to fully or partially realize the automatic driving function of EV. According to IHS Automotive forecast, with the popularity of driverless cars rising, to 2035, with a certain degree of automatic driving function of the vehicle will increase to about 21 million vehicles, of which the United States approximately 4 million 500 thousand vehicles.
Looking ahead
Several factors are driving the growth of electric vehicles, including specific emission reduction legislation, integrated consumer products to enhance driving safety technology and car ownership to the mobile service transition.
