Anggaran keadaan kesihatan (SOH) masa nyata bateri litium-ion untuk kenderaan elektrik (EV) adalah penting untuk penyelenggaraan EV. Mengikut situasi dalam aplikasi praktikal seperti masa ujian kapasiti bateri EV yang panjang, ketiadaan ujian harian biasa dan ketersediaan data caj kitaran hayat penuh EV yang direkodkan pada platform data besar kemudahan pengecasan, kertas kerja ini mengkaji penggunaan dalam talian. Kaedah anggaran keadaan kesihatan EV menggunakan regresi proses Gaussian yang dilanjutkan-Kalman penapis (GPR-EKF) untuk menggabungkan data bateri litium-ion pada skala masa makro dan skala masa mikro berdasarkan data caj harian kenderaan elektrik. Kaedah ini mencadangkan fungsi kernel GPR (regresi proses Gaussian) yang menyepadukan rangkaian neutral dengan kitaran untuk menjalankan pemasangan data pada skala masa makro untuk menentukan hingar pengukuran berwarna; selain itu, data caj serpihan pada skala masa mikro dilaraskan dengan lelaran masa nyata untuk digunakan sebagai persamaan keadaan, yang menangani isu penentukuran dan bukan linear masa nyata SOC secara berkesan. Kepentingan, keberkesanan dan prestasi masa nyata algoritma model dalam anggaran keadaan kesihatan bateri dalam talian disahkan oleh data sebenar.

Abstract: The real-time state-of-health (SOH) estimation of lithium-ion batteries for electric vehicles (EV) is essential to EV maintenance. According to situations in practical applications such as long EV battery capacity test time, unavailability of regular daily tests, and availability of full-life-cycle charge data of EV recorded on the charging facility big data platform, this paper studies an online in-use EV state-of-health estimation method using iterated extended Gaussian process regression-Kalman filter (GPR-EKF) to incorporate lithium-ion battery data at the macro time scale and the micro time scale based on daily charge data of electric vehicles. This method proposes a kernel function GPR (Gaussian process regression) integrating neutral network with cycles to conduct fitting for data at the macro time scale to determine colored measurement noise; in addition, fragment charge data at the micro time scale is adjusted with real-time iteration to be used as the state equation, which effectively addresses issues of real-time SOC calibration and nonlinearization. The pertinence, effectiveness and real-time performance of the model algorithm in online battery state-of-health estimation is verified by actual data.
