Abstract

The growing adoption of electric vehicles (EVs) is a key component of Spain’s strategy for achieving sustainable transportation and energy systems. This paper analyses EV charging behaviour using individual smart meter data from over 20,000 Spanish EV users, offering insights into charging session timing, duration, energy consumption, and power load trends—including variations among regions and tariff structures-.

Our findings show that most charging sessions take place during the nighttime tariff period (1:00 AM to 7:00 AM), when electricity prices are lower, highlighting the effectiveness of time-of-use pricing in shifting demand to off-peak hours. However, this behaviour also leads to a coincident peak in electricity consumption, which could pose challenges as EV adoption increases and may require further attention to avoid grid stress.

Leveraging a large, representative dataset in the Spanish context, the results of this study provide valuable insights for policymakers and energy market stakeholders seeking to optimize EV integration and mitigate the potential impacts of widespread electrification.

分析西班牙的电动汽车充电行为：模式和见解

越来越多的电动汽车（ev）的采用是西班牙实现可持续交通和能源系统战略的关键组成部分。本文利用来自2万多名西班牙电动汽车用户的个人智能电表数据分析了电动汽车的充电行为，提供了对充电时间、持续时间、能源消耗和电力负荷趋势（包括地区和电价结构之间的差异）的见解。我们的研究结果表明，大多数充电发生在夜间电价时段（凌晨1点至7点），此时电价较低，突出了分时电价在将需求转移到非高峰时段的有效性。然而，这种行为也会导致电力消耗同时达到峰值，随着电动汽车的普及，这可能会带来挑战，可能需要进一步关注以避免电网压力。利用西班牙背景下的大型代表性数据集，本研究的结果为政策制定者和能源市场利益相关者寻求优化电动汽车整合和减轻广泛电气化的潜在影响提供了有价值的见解。

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
