BYD Seagull is fully charged at 40 degrees. As a pure electric car, the biggest advantage of BYD Seagull is environmental protection. Compared with traditional fuel vehicles, Seagull is powered by batteries, which can reduce exhaust emissions to a certain extent. In addition, Seagull also has a high cost performance and is relatively affordable, so it is favored by consumers. Secondly, BYD's Seagull costs less because it is a pure electric model. The model with a range of 400 kilometers is fully charged with 40 kilowatt-hours of electricity. Household electricity costs 6 cents per kilowatt hour, which is 24 yuan for 40 kilowatt-hours of electricity, which is only 6 cents per kilometer. Compared with traditional fuel vehicles, new energy vehicles have the following environmental advantages. Reduce carbon emissions: New energy vehicles do not use fuel for combustion, thus reducing emissions of greenhouse gases such as carbon dioxide, helping to alleviate global climate change problems. Pure electric vehicles have absolutely no exhaust emissions during use. Reduce air pollution: Exhaust emissions from traditional fuel vehicles produce air pollutants such as carbon monoxide, nitrogen oxides and particulate matter. The zero-emission characteristics of new energy vehicles improve urban air quality and reduce health hazards. Saving energy resources: New energy vehicles use renewable energy or more efficient energy conversion technology, reducing dependence on limited resources such as oil. This helps achieve sustainable use of energy and avoids economic risks caused by oil price fluctuations. Reduced sound pollution: The engine noise of traditional fuel vehicles has a negative impact on the quality of life of urban residents. In contrast, the electric drive system of new energy vehicles operates more quietly, reducing noise pollution. Renewable energy integration: There are good synergies between new energy vehicles and renewable energy. By combining solar charging piles, wind power and other renewable energy facilities, green charging of new energy vehicles can be achieved, further improving their environmental friendliness.
