Life-Cycle Cost-Benefit Measurement Model of Electric Vehicle AC Charging Piles in Residential Communities

To implement the emission peak and carbon neutrality, and promote the construction of "new infrastructure, new urbanization initiatives and major projects", power grid companies are actively exploring the development of electric vehicle charging service business. As far as they increase the investment in charging infrastructure in response to the national strategy, it is particularly important to improve the environmental and economic benefits of charging infrastructure at this stage. This paper establishes a life-cycle cost-benefit measurement model of electric vehicles AC charging piles in residential communities. According to the input parameters, the model simulates the life-cycle CO2 emissions of the generation side, the life-cycle net income of AC charging piles in residential communities and the impact of AC charging pile loads on the grid. The empirical results show that the life-cycle cost-benefit measurement model can guide the realistic investment-construction-planning of AC charging piles, which can improve the environmental and economic effects of grid companies.
