AI Customer ServiceBattery technology in EVs When discharged, a battery produces electrical energy by converting chemical energy, and when charged, it converts electrical energy back into chemical energy. Batteries are composed of electrochemical cells placed in a parallel–series configuration.
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.
In this article, a novel battery fault diagnosis method is presented by combining the long short-term memory recurrent neural network and the equivalent circuit model. The modified adaptive boosting method is utilized to improve diagnosis accuracy, and a prejudging model is employed to reduce computational time and improve diagnosis reliability.
The operating performance of EVs is significantly affected by the reliability and security of the battery systems. Internal short-circuiting, external short-circuiting, overcharging, sensor faults, actuator faults, connections, and insulation faults are the different categories of faults associated with batteries.
Generally speaking, power battery system faults can often be traced back to specific individual cells, and the fault characteristics can be reflected in the cell voltage in real time, and are mostly manifested as inconsistent fluctuation.
Concerns regarding battery production and its deterioration over time have significantly increased in recent years . These batteries can be recharged with power from the grid or any other source through a charging port [, , , ]. BEVs require slightly longer charging times than traditional ICE-based vehicles.
