Research on Operating Costs of Carbon Quota Accounting Based on Time Division of New Energy Buses

Amid escalating environmental and energy-related challenges, the advancement of electric vehicles has become a pivotal national strategy in China for energy conservation and emission reduction. This study presents an analysis of the methodology used for calculating energy consumption in electric vehicles in comparison to traditional fuel vehicles. The customary practice of assigning monetary value to carbon emissions is integrated to transmute carbon emission reduction methods into fiscal terms. This transformation enhances suitability for evaluating energy transitions and benefit comparisons. Concurrently, data from the New Energy Vehicle Open Laboratory V 2.0 were used to calculate the carbon quota produced throughout the charging and operating procedures of the national new energy public transportation in 2019. Additionally, charging expenses were calculated considering the varying electricity prices at different times of the day, and an assessment was conducted on the reduction of operating costs resulting from the annual benefits of carbon emission reduction. It is evident that, given the current carbon emission factor of China 's power grid, electric buses have successfully transitioned their emission reduction effect from negative to positive.
