Abstract

The adoption of electric vehicles (EVs) is transforming the landscape of energy consumption. While the technical and economic dimensions of EV adoption are increasingly well understood, the aspect of justice in demand flexibility remains underexplored. This study examines the complex relationship between flexibility in EV charging behaviors and the influence of socio-psychological and justice factors. We explore a range of demographic and social-psychological variables including charging anxiety, environmental concerns, perceived cost-saving perception, perceived privacy, and trust in utility providers. Our results reveal that these variables positively influence the changes in charging habits, including time-shifting and load-reduction. This study also uncovers disparities in charging behavior adjustments across various demographics groups. For instance, White respondents are more likely to charge their EVs during off-peak hours than their non-White counterparts and homeowners show a greater intention to reduce EV charging load during peak hours compared to renters. Additionally, high-income individuals exhibit a stronger willingness to shift charging times to off-peak, with White respondents within the high-income group being the most likely to reduce the amount of charging load during peak hours. Conversely, low-income White respondents are less inclined to make such adjustments. These disparities are likely tied to socioeconomic status, as more vulnerable groups often face greater constraints in adjusting their schedules. Therefore, it is imperative that policies prioritize flexibility justice by addressing the specific needs and behaviors of vulnerable groups, aiming to mitigate the additional burdens resulting from their limited flexibility.
灵活性正义:探索电动汽车充电行为、需求灵活性和心理因素之间的关系
电动汽车(EV)的采用正在改变能源消耗的格局。尽管人们对采用电动汽车的技术和经济层面越来越了解,但对需求灵活性中的公正性方面仍然缺乏探索。本研究探讨了电动汽车充电行为灵活性与社会心理和公正因素影响之间的复杂关系。我们探讨了一系列人口和社会心理变量,包括充电焦虑、环境问题、成本节约感知、隐私感知以及对公用事业供应商的信任。我们的研究结果表明,这些变量对充电习惯的改变有积极影响,包括分时充电和减少负荷。这项研究还发现了不同人口群体在充电行为调整方面的差异。例如,与非白人受访者相比,白人受访者更倾向于在非高峰时段为电动汽车充电;与租房者相比,房主更倾向于在高峰时段减少电动汽车充电负荷。此外,高收入人群更愿意将充电时间转移到非高峰时段,高收入人群中的白人受访者最有可能减少高峰时段的充电负荷量。相反,低收入的白人受访者则不太愿意进行此类调整。这些差异很可能与社会经济地位有关,因为弱势群体在调整时间表时往往面临更大的限制。因此,政策必须优先考虑灵活性正义,解决弱势群体的具体需求和行为,旨在减轻他们因灵活性有限而造成的额外负担。

期刊介绍: Energy Research & Social Science (ERSS) is a peer-reviewed international journal that publishes original research and review articles examining the relationship between energy systems and society. ERSS covers a range of topics revolving around the intersection of energy technologies, fuels, and resources on one side and social processes and influences - including communities of energy users, people affected by energy production, social institutions, customs, traditions, behaviors, and policies - on the other. Put another way, ERSS investigates the social system surrounding energy technology and hardware. ERSS is relevant for energy practitioners, researchers interested in the social aspects of energy production or use, and policymakers. Energy Research & Social Science (ERSS) provides an interdisciplinary forum to discuss how social and technical issues related to energy production and consumption interact. Energy production, distribution, and consumption all have both technical and human components, and the latter involves the human causes and consequences of energy-related activities and processes as well as social structures that shape how people interact with energy systems. Energy analysis, therefore, needs to look beyond the dimensions of technology and economics to include these social and human elements.
