Electric vehicle (EV) purchasing decisions are significantly influenced by costs. Focusing on China, this research comprehensively examines the levelized costs of EV recharging (including charging and swapping) at the provincial level considering various factors, including charging locations, time of charging, and power levels. Results indicate that the national average EV charging costs, with and without home chargers, amount to 0.973 RMB/kWh and 1.148 RMB/kWh, respectively. Remarkable variations are observed among provinces, with Xinjiang and Shanghai experiencing the lowest and highest levelized cost of EV charging (LCOC), respectively, with disparities of up to 147.26%, primarily attributed to regional discrepancies in electricity prices and vehicle usage intensity. Despite generous capital subsidies, swapping costs remain considerably higher than charging, ranging from 3.780 RMB/kWh to 4.082 RMB/kWh. Additionally, the sensitivity analysis of major parameters, including infrastructure utilization, suggests that levelized EV recharging costs are already more cost-attractive than the fuel costs of comparable gasoline cars at today's utilization rates.
电动汽车(EV)的购买决策受成本影响显著。本研究聚焦于中国,全面考察了省级层面电动汽车充电(包括充电和换电)的平准化成本,考虑了各种因素,包括充电地点、充电时间和功率水平。结果表明,有无家用充电器情况下,全国电动汽车充电成本平均分别为0.973元/千瓦时和1.148元/千瓦时。各省份之间存在显著差异,新疆和上海的电动汽车充电平准化成本(LCOC)分别为最低和最高,相差高达147.26%,主要归因于电价和车辆使用强度的地区差异。尽管有大量资金补贴,但换电成本仍远高于充电成本,范围在3.780元/千瓦时至4.082元/千瓦时之间。此外,包括基础设施利用率在内的主要参数的敏感性分析表明,在当前利用率下,电动汽车充电平准化成本已经比可比汽油车的燃料成本更具成本吸引力。
