摘要

为了进一步推动电动汽车的普及,车对物(V2X)技术,包括车对家(V2H)和车对电网(V2G)应用,已变得越来越重要。然而,车主普遍担心 V2X 部署可能会加速电池老化。针对这些问题,本文提出了一种系统方法来量化各种充电策略下的电动汽车电池老化。我们在反映真实世界驾驶和 V2X 应用特点的设计条件下进行了细致的电池老化实验。此外,我们还进行了全面的参数研究,以探索 V2X 应用与电池老化之间错综复杂的关系。实验结果表明,在 20 个月后,所有 V2X 场景和参考场景之间的老化差值为 3.09% SOH,低于文献报道的相同条件下电池制造差异造成的差值。参数研究结果表明,与传统的不可控充电策略相比,除了主要的移动性前景外,采用 V2X 应用不会显著增加电池老化,如果配置得当,甚至可以减少容量损失。

Quantifying the impact of V2X operation on electric vehicle battery degradation: An experimental evaluation

To further boost electric vehicle adoption, Vehicle-to-Everything (V2X) technology, including Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) applications, has gained prominence. However, a prevailing concern of owners pertains to the potential acceleration of battery aging associated with V2X deployments. In response to these concerns, this paper presents a systematic approach to quantify EV battery degradation across various charging strategies. We conduct meticulous battery aging experiments under designed conditions reflecting the characteristics of real-world driving and V2X applications. Furthermore, a comprehensive parameter study is carried out to explore the intricate relationships between V2X applications and battery degradation. Our experimental results show that the aging spread between all V2X and reference scenarios of 3.09% SOH after 20 months is lower than the spread caused by cell-to-cell manufacturing variation under identical conditions reported in the literature. The results of the parameter study reveal that adopting V2X applications, in addition to primary mobility prospects, does not significantly increase battery degradation and can even reduce capacity loss compared to the conventional uncontrolled charging strategy if properly configured.

期刊介绍: eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation. The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment. Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
