The emergence of start-stop batteries in China dates back to the 1980s. It was not until the 21st century that it began to enter the popularization period.
The current situation in China
The Chinese government has introduced regulations on vehicle exhaust emissions.
Development Trends
In terms of bus market share in China/ US/Europe: The main direction of development at present is to improve fuel efficiency, save fuel and improve the environment, and reduce CO2 emissions.The emerging hybrid electric vehicles are practical and can use low-cost, safe lead-acid batteries as start-stop batteries, which can initially save fuel and reduce emissions (about 7%). Inparticular, the start-stop lead-acid battery (Pb/C battery) of the "mild hybrid" vehicle has the advantages of strong dynamic charging acceptance, good durability and high reliability. Lead-carbon start-stop batteries suitable for "mild hybrid" vehicles are currently being vigorously developed and developed in China.
Environmental conditions: Since 2012, the frequency of very severe smog has been increasing, causing deterioration of the urban environment, especially in large cities.
In January 2014, "Limits on Vehicle fuel consumption" and "Methods and Indicators for Evaluating Passenger Vehicle Fuel Consumption" were released, both of which set requirements for gasoline consumption."Mild hybrid" car manufacturers are increasingly referring to "mild hybrid"cars, while general clients cannot meet the relevant conditions for the start-stop battery of "mild hybrid" cars due to cost considerations and time constraints.
The start-stop technology was introduced in China relatively late and is expected to thrive in the next 3 to 5 years (with an estimated peak around 2020)
The new energy policy issued by the state, "Energy Conservation Development Plan for the Automotive Industry and New Energy Vehicles" will promote greater development of China's
automotive industry and the production of more efficient and diverse hybrid vehicles, electric vehicles and pure battery-powered electric vehicles. Around 30 million vehicles worldwide are equipped with start-stop systems. The same is true in China, where there has been a very rapid development process since 2011, with a peak expected between 2019 and 2022.
In Europe, new development of OEM vehicles is expected to exceed 70% by 2017.
Around 30 million vehicles worldwide are equipped with start-stop systems. The same is true in China, where there has been a very rapid development process since 2011, with a peak expected between 2019 and 2022.
In terms of demand for new cars in the world's six major economies (countries), the first is China, the second is the United States, the third is Japan, the fourth is Brazil, the fifth is Germany, the sixth is lndia, and the seventh is other countries.
In terms of bus market share in China/ US/Europe:
In 2013, 82 % of vehicles were were hybrid and electric vehicles, 1% conventional ( engines ), about 14% were " micro hybrids" with start-stopsystems, and about 3% were plug-in hybrids or pure battery powered vehicles. It is estimated that by 2017, 39 % of vehicles will be conventional(engine cars), 50 % will be hybrids, about 4 % will be " micro hybrid" vehicles with start-stop systems and about 2 % will be pure battery powered vehicles. Judging from the market development of automobile batteries in China, the Chinese government required the production of new energy vehicles in 2013.By 2015, about 500,000 electric vehicles and hybrid electric vehicles were produced, and the production capacity will increase to 2,000,000 units / year by 2020, accounting for about 5 % of the total production vehicles.
In China, there are many reasons for the rapid development of start-stop systems for automobiles, which can be summarized as follows.
Air pollution has become very serious, especially since 2013 due to a large number of automobile exhaust emissions.
The ambient air cleanliness index requires a 25 % reduction in emissions in big cities such as Beijing,Shanghai and Tianjin by the end of 2017, and a 10 % reduction in emissions in other regions.
Automobile standards will be implemented from January 2018. Beijing and Tianjin have been implemented in September 2013 and April 2014 respectively.
Cars, motorcycles and trucks that do not meet the automobile standards in China by 2018 are not allowed to leave the factory.
" Vehicle Fuel Consumption Limit" and " Evaluation Method and Index of Bus Fuel Consumption" were put forward by the Ministry of Industry in January 2014. It is required to be implemented from 2016 to 2020. Vehicle energy consumption and emissions will be more and more strictlycontrolled, and new standards will be implemented for all vehicles on the market.
Energy consumption and the development of new energy automobile industry( 2012~ 20.20) have been clearly stipulated in China.It is predicted that the average gasoline consumption of passenger cars will reach the target of 6.9L/ 100km by the end of 2015. 5.0L/100km by 2020.
Generally speaking, the "micro-hybrid" vehicle with start-stop device will be rapidly popularized and applied in China because it meets the national environmental protection requirements and the national legal requirements for reducing CO2 emissions and has the advantage of improving fuel efficiency ( i.e. reducing oil consumption ). At present, the start-stop battery has been applied to several models in China.
