With the increasing environmental pressure, the goal of energy saving and emission reduction seems very daunting. It is reported that some cities in China have even started to detect PM2.5 since 2012, which makes practitioners feel strongly that, no matter what difficulties new energy vehicles encounter temporarily (high prices, imperfect infrastructure), market factors are strongly pushing semiconductor manufacturers, system manufacturers, car manufacturers, and even business model manufacturers (national grid, CNPC Sinopec) to move forward. Fujitsu Semiconductor Shanghai Co., Ltd. marketing product manager Ding Jie has long said, from the semiconductor level, to promote the new energy vehicles market factors have now formed.

It is reported that in 2012, the major car manufacturers are planning more suitable for the market demand of entry-level new energy vehicle products, the government will work with specific operating companies to charge / switch station infrastructure construction arrangements for more financial support and give policy support. "As an important supplier of automotive semiconductors, Fujitsu Semiconductor will make efforts in the new energy vehicle market in 2012, including working with partners to make new energy vehicles really develop from 10,000 units to 100,000 units or even to 500,000 units, and reach the industrial plan of one million units by 2016." Ding Jiezao said.

In 2012, China is expected to take the lead in the number of new energy vehicle models and infrastructure construction of charging and switching stations, but more innovation is needed in the new generation of power batteries and drive motor control. The U.S. government's policy is focused on the development and industrialization of power battery technology, and their idea is "who has mastered the power battery technology, who will occupy the future of electric vehicles". Europe will continue to integrate the technology of global excellent partners to promote the joint development of new energy vehicle industry, while taking advantage of the huge market potential and low production costs in developing countries to quickly occupy the market. Japan will continue to promote their hybrid electric vehicle development plans, while promoting the global export of new energy vehicles.

Whether it is a traditional car or a new energy vehicle, safety, green, comfortable car electronic system is a common demand, car safety including zero failure, functional safety and self-diagnostic module; environmental friendliness refers to the use of on-board networks to reduce the weight of the vehicle, thereby reducing energy consumption, but also includes the use of environmentally friendly materials and processes; powerful graphic image processing technology, intuitive and friendly human-machine interface are for the driver to bring a comfortable The driver's driving experience. These needs will be mainly related to four areas of automotive electronics: body electronics, body instrument panel, image multimedia, and chassis motor control.

For the new energy vehicle market, Fujitsu Semiconductor is providing a one-stop system control solution. Ding Jiezao said that just providing a chip cannot solve the problem. Fujitsu's idea is to reduce the cost of research and development, reduce the threshold of design, reduce the cost of the chip, and ultimately provide a one-stop system control solution (including work units, battery management, motor control and conversion units, etc.), so as to bring down the cost of research and development systems.

Fujitsu Semiconductor offers a package solution that basically covers the entire electronic system of an EV/HEV. From the MB91580 series dedicated motor control 32-bit MCU solution with integrated internal RDC, to the graphical virtual display instrumentation with Fujitsu GDC solution; from the BMS solution and DC-DC converter designed with low-cost MB96F613 using CAN bus, to the whole vehicle controller developed with multiple CAN bus MCU FR81S. Moreover, these different grades of 16-bit and 32-bit MCUs all use the same low-cost emulator and the same compilation environment, making development very convenient and inexpensive.

In motor control, Fujitsu Semiconductor proposes motor control MCU solution innovations for EV/PHEV, including: 1. improve motor operation; 2. reduce energy consumption; 3. reduce system cost. the MB91580 MCU is the world's first high-performance MCU dedicated to new energy vehicle motor control, integrating key peripheral functions such as RDC, which can shorten motor control time and Simplify system design.
