Summary/Abstract

Consumer attitude toward electric vehicles is very important for clean development. Chen and Lin (2022) explored the impact of consumer behavioral characteristics on satisfaction with electric vehicle charging infrastructure. The research team builds on this study for further research from a dynamic perspective. This study utilized 3778 valid samples from two cross-sectional surveys conducted in 2019 and 2023 to explore the differences in behavioral characteristics and satisfaction across periods and cities. Mechanisms of influence were also discussed. The main findings include: (1) Consumer satisfaction has increased in 2023 compared to 2019, while charging habits have changed in favor of nighttime charging. Additionally, consumers have lower requirements for charging time and price, and higher requirements for charging infrastructure distribution. (2) Consumers in non-first-tier cities are more receptive to charging infrastructure farther from homes than consumers in first-tier cities. (3) In current first-tier cities, preference for daytime or nighttime charging no longer affects consumer satisfaction, while the price increase sensitivity has a less significant effect on consumer satisfaction in non-first-tier cities. (4) Consumer perceived control and expectation disconfirmation are found to be important mechanisms through which behavioral characteristics affect satisfaction. Finally, this study proposes targeted policy implications based on the findings.

Summary/Abstract

This paper estimates the charging demand of an early electric vehicle (EV) market in Beijing and proposes an assignment model to distribute charging infrastructure. It finds that each type of charging infrastructure has its limitation, and integration is needed to offer a reliable charging service. It also reveals that the service radius of fast charging stations directly influences the final distribution pattern and an infrastructure deployment strategy with short service radius for fast charging stations has relatively fewer disturbances on the power grid. Additionally, although the adoption of electric vehicles will cause an additional electrical load on the Beijing's power grid, this additional load can be accommodated by the current grid's capacity via the charging time management and the battery swap strategy.
