Data-Driven State of Charge Estimation Based on Extended Kalman Filtering LIU Jianfeng 2025, 50(7): 1-7.  DOI: 10.16638/j.cnki.1671-7988.2025.007.001 Abstract ( )   PDF (1001KB) ( )   Accurately estimating the state of charge (SOC) is challenging due to the changing environmental conditions in which batteries operate. Accurate SOC estimation not only prevents battery overcharging and overdischarging, but also provides accurate range predictions and extends battery life. In this paper, a SOC estimation method for lithium-ion batteries based on a combination of extended Kalman filter (EKF) and data-driven is adopted. Firstly, the recursive least squares method with forgetting factor (FFRLS) is used to dynamically track the characteristic parameters of the battery model. Secondly, the results of the EKF algorithm are input into the Extreme Gradient Boosting (XGBoost) model as training data. With the machine learning and prediction capabilities of XGBoost, combined with the EKF algorithm, high-precision estimation of battery SOC is realized.The simulation results show that the combined algorithm adopted in this paper is better than the EKF and traditional machine learning algorithms in terms of convergence and accuracy. In addition, the results show that the method can achieve accurate SOC estimation and provide accurate and stable SOC values by verifying under different working conditions.

However, calibration relies on the actual vehicle and cannot meet the needs of system selection and energy consumption status evaluation in the early design stage. To solve this problem, this paper adopts the AMESim physical model and strategy model joint simulation method to achieve virtual calibration and optimization of the vehicle's energy consumption prediction and energy management strategy, meeting the requirements of system selection and control strategy development based on energy consumption goals. This paper takes extended range electric light truck as the research object, with the goal of achieving pure electric range and optimal fuel consumption for electric balance. It introduces a power level classification strategy and designs a differentiated energy control strategy based on power level to meet the energy management requirements of different scenarios such as pure electric range, high load power demand, and power maintenance ability. Through strategy optimization and real vehicle verification, the goal of pure electric range greater than 120 km in Chinese operating conditions has been achieved, and the optimal fuel consumption design for operating on the best economic line and achieving electric balance has been achieved.

Microcosmic Teaching Design of Disassembly and Assembly of Permanent Magnet Synchronous Motor Course Based on Work Process CHANG Yu1 , SHEN Rongwei1 , HUANG Jinjiao1 , CHANG Wenjun2 , LI Guo3 2025, 50(7): 143-146.  DOI: 10.16638/j.cnki.1671-7988.2025.007.028 Abstract ( )   PDF (1723KB) ( )   At present, there is a situation of "three highs and three difficulties" in the actual teaching of new energy vehicle majors in vocational colleges, which cannot achieve the expected teaching goals. This article explores the integrated teaching mode of theory, reality, and virtuality, based on the action oriented six step macro teaching method, using task driven method, brainstorming method, group cooperation method, and other to enrich teaching links and promote students to master professional core skills. Taking Disassembly and Assembly of Permanent Magnet Synchronous Motor course as an example for classroom practice. Through a survey questionnaire method, it is found that students have a high overall satisfaction with the integrated teaching mode of theory,virtuality, and reality. The application of virtual reality (VR) technology reduces the difficulty of complex principle knowledge, increases the safety factor of practical training, and can effectively stimulate students' interest in learning.
