摘要

交通运输部门的脱碳正在成为21世纪的一个关键焦点。随着内燃机汽车的普及程度下降,混合动力汽车和电动汽车(ev)的采用正在显著增加。除了安全问题,电池驱动汽车面临的主要挑战之一是有限的行驶里程和频繁的充电要求。将光伏(PV)模块集成到车辆表面,可以在运动和静止期间持续充电,从而延长车辆充满电的范围。本研究的主要贡献有两方面:一是基于0.8 voc的最大功率点跟踪(MPPT)方法的改进,该方法适用于快速变化辐照度条件下的平板车载集成光伏(VIPV)系统;二是对经典最大功率点跟踪(MPPT)方法进行了长期仿真分析,采用两个新的指标来衡量不同辐照度情况下的续航里程扩展和车辆充电频率变化。与增量电导(IC)算法和变步长(VSS)摄动和观察(P&;O)方法相比,所提出的MPPT方法产生了更优越的能量性能,产生的能量高出16 - 25%。对三款电动汽车车型进行的长期模拟表明,使用185W光伏模块,每日行驶里程可延长2-7公里,同时充电频率最多可减少19%,具体取决于电池容量和车型。

Performance assessment of solar-powered electric vehicles: Importance of maximum power point tracking, range enhancement and charging frequency analysis under various operating and irradiance conditions
Decarbonizing the transportation sector is becoming a crucial focus in the 21st century. As the popularity of internal combustion engine vehicles declines, the adoption of hybrid and electric vehicles (EVs) is significantly increasing. One of the main challenges for battery-powered vehicles, aside from safety concerns, is the limited driving range and frequent charging requirements. Integrating a photovoltaic (PV) module onto a vehicle's surface enables continuous battery charging during both motion and stationary periods, thereby extending the vehicle's range on a full charge. This study presents two main contributions: a modified 0.8VOC-based maximum power point tracking (MPPT) method for fast-changing irradiance conditions for flat-roof vehicle-integrated PV (VIPV) systems, and a long-term simulation analysis of classical MPPT methods using two new indicators for range extension and vehicle charging frequency variations under different irradiance profiles. The proposed MPPT method yielded superior energy performance, achieving 16–25 % higher energy generation compared to both the incremental conductance (IC) algorithm and the variable step-sized (VSS) perturb and observe (P&O) method. Long-term simulations conducted for three EV models demonstrated a daily driving range extension of 2–7 km with an 185W PV module, along with up to a 19 % reduction in charging frequency, depending on the battery capacity and vehicle models.
