According to foreign reports, Bosch is optimistic about the prospects of the start-stop system in the Chinese market. Executives expect that by the year 2019, 30% of cars in China will use a start-stop system. In July 2013, Sun Guozhong, President of Bosch's Starter and Motor Division China, stated at an industry conference in Beijing that 40% of European light-duty vehicles used a start-stop system in 2013, and this ratio is expected to increase to 2019. 90%; The Chinese market will follow the pace of Europe in this area. “In 2019, the annual sales volume of China’s auto market will reach 30 million, of which 30% will be equipped with a start-stop system . One out of every three vehicles will be equipped with - Stop the system." The start-stop system shuts down the engine when the car is stopped at red light to prevent idling; when the car's brake pedal is released and the clutch is engaged, the battery will restart the engine. The above measures can effectively reduce vehicle fuel consumption. Organizations such as the Massachusetts Institute of Technology confirmed vehicle fuel economy and emission targets for 2015 and 2020 last year. The start-stop system is listed as one of the means of reducing consumption and can reduce emissions by 8% to 15%. Bosch has introduced start-stop system technology to China since 2008. Sun Guozhong said that the company has more than a dozen corporate clients in China, including German luxury car manufacturers Audi and BMW, as well as its own brands Great Wall and Changan, etc.; Bosch is located in Changsha. The factory will produce 700,000 sets of start-stop systems this year, well above the 200,000 units in 2012. However, Sun Guozhong pointed out that the promotion of the start-stop system in China has only just begun. “The popularization of stop-start systems in China will face three major problems: first, the limitations of laws and regulations, followed by the limited understanding of start-stop systems by users, and It is the Bosch AGM battery that relies on imports and has limited capacity."
