Summary:

Electric vehicles play a key role in China’s plan to improve air quality and reduce CO2 emissions but, with the majority of China’s electricity still coming from coal-fired power plants, many question just how effective this strategy will be. Now, researchers have found that how electric vehicles are charged — whether in the low-energy slow mode or high-energy fast mode — plays a significant role in the reduction of CO2 and the integration of wind energy.

In order to improve the earth environment,China has launched many strategies to solve this problem,electric vehicles are one of them .Qiangsheng Group is trying to help finish this goal.

Qiangsheng Factory is a professtional enterprise that specializing in electric tricycle R&D, production ,sales ,trading and spare parts service. Qiangsheng owns the most advanced production line and detection equipment,professtional welding/ machining/electrophoresis painting/assembly workshops.Also have strict QC system to ensure high quality.

Now, researchers from Harvard University and Tsinghua University in Beijing found that private electric vehicles in China can have a positive effect on CO2 reduction if owners can be incentivized to slowly charge vehicles during off-peak hours, allowing for more effective use of  water-generated power. Quickly charging vehicles in the higher energy “fast mode,” on the other hand, can be counterproductive. Qiangsheng has always been calling for the usage of New energy and striving to research new type.

Meanwhile, buses and taxis In China make a significant contribution to NOX emissions, a major precursor for air pollution. We Qiangsheng are always engaged in manufacturing electric tricycles and motorcycles ,which can help reduce air pollution greatly.The team determined that electrifying the bus and taxi fleet offers the most effective option for improving air quality.

The research is published in Nature Energy.

“This research offers a more nuanced strategy for reducing CO2 emissions and improving air quality in China,” said Michael B. McElroy, the Gilbert Butler Professor of Environmental Studies at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Department of Earth and Planetary Sciences and co-author of the research.

“It is critically important that electric vehicle charging is managed properly to maximize the benefits of renewables,” said Xinyu Chen, Research Associate in Environmental Science and Engineering at SEAS and co-author of the study.We believe that rechargeable batteries will welcome a giant development,everyone can really enjoy the profits of green power.

The researchers used real-time power demand data and driving patterns for Beijing and its suburbs to develop a comprehensive model of the energy system. They found that how electric vehicles are charged — whether in the low-energy slow mode or high-energy fast mode — plays a significant role in the integration of wind energy. Typically, vehicle charging in the 30-minutes or less fast mode occurs during hours of peak power demand. As a result, peak power demand is increased, triggering additional coal generators to come online. With these generators operational at night, the opportunity to take advantage of available wind power is reduced.

“If people were incentivized to wait until evening and charge their vehicles in the slow-charge mode, which takes hours, the power load could take advantage of wind energy available during off-peak hours,” said Chris P. Nielsen, Executive Director of the Harvard China Project and co-author of the study.

In terms of lowering air pollution, the researchers found that the gas- or diesel-fueled fleet of public vehicles — about 30,000 buses and 66,000 taxis — is responsible for nearly 20 percent of total NOX emissions, equivalent to the contribution from 8.2 million private vehicles. Electrifying the fleet of buses and taxis in Beijing would significantly reduce total NOX emissions and increase air quality.

“Electrifying the public fleet and introducing incentives to charge personal electric vehicles at off-peak times would be the most effective strategy to reduce NOX and CO2 emissions in Beijing,” said McElroy. “This strategy could also be applied to cities across the world that have a significant source of electricity from coal.”Qiangsheng will also be doing our best to update.
