This paper presents a method for the monitoring and early warning of electric vehicle charging faults based on a battery model. A second-order dynamic circuit model of the power battery is proposed to simulate the charging characteristics of the battery.
In this paper, the fault diagnosis of battery systems in new energy vehicles is reviewed in detail. Firstly, the common failures of lithium-ion batteries are classified, and the triggering mechanism of battery cell failure is briefly analyzed. Next, the existing fault diagnosis methods are described and classified in detail.
Due to road conditions, technology and other reasons, the storage battery, as a weak link of electric vehicles, is a frequent occurrence point of faults and the focus of fault diagnosis (Wang et al. 2017). The purpose of intelligent fault diagnosis of electric vehicles is to detect faults in the system based on actual detection data.
World Electr. Veh. J. With the development of electric vehicles in China, the fault monitoring and warning systems for the charging process of electric vehicles have received the industry’s attention. A method for the monitoring and warning of electric vehicle charging faults based on a battery model is proposed in this paper.
In view of the shortcomings of current electric vehicle charging fault monitoring methods, this paper proposes an electric vehicle charging fault monitoring and early warning method based on the battery model, which can identify more than 10 types of faults including BMS (Battery Management System) function failure. 2.
While BMS are designed to prevent over-charging by monitoring the SOC, factors like different charging modes (e.g., fast charging) and charging rates can lead to over-charge [69, 70]. Additionally, BMS misjudgment due to sensor faults can cause prolonged over-charging. The design and quality of battery cells also play a role.
