by ]Lithium batteries are important components of various electrical devices. And accurate lifetime prediction is essential to maintaining optimum performance. But the non-linear nature of the capacitance decay and the uncertainty associated with the operating conditions. This makes it a complex task to accurately predict battery life…
]Accurate prediction of lithium battery life is critical to the proper operation of power tools. However, accurate prediction of battery life is challenging. Due to the nonlinearity of capacity reduction and the uncertainty of operating conditions, Professor Chen Zhongwei and S.S. Prof. Mao Ziyu from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences recently collaborated. Together with Professor Feng Jiangtao from Xi’an University, Jiaotong designed a new deep learning model. which has a self-interest mechanism (DS-ViT-ESA) and effective current cycle life (CCL) of the target battery. and predict remaining useful life (RUL). The study is published in the journal IEEE Transactions on Transportation Electrification.
]The researchers developed a deep learning model using a small amount of charging cycle data. This model uses a visual transformation structure with a dual-stream framework and an efficient self-attention mechanism to capture and integrate hidden features across time periods.
]The model can accurately predict the CCL and RUL of a battery. With only 15 charging cycle data points, RUL and CLL prediction errors were only 5.40% and 4.64%, respectively. Moreover, the model maintained low prediction errors. Although testing a charging strategy that was not included in the training dataset. Which shows the ability to generalize to zero…
]The battery life prediction model is also a key component of the first generation battery digital brain called PBSRD Digit. The accuracy of the system integrated with this algorithm has been significantly improved. Batteries serve as the primary energy management system for large-scale commercial energy storage and storage systems….
]Recently, a team of researchers from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, led by Prof. Chen Zhongwei and S.K. Professor Mao Xiu, collaborated with Professor Feng Jiangtao from Xi’an Jiaotong University to develop a deep learning model. New style It is a dual stream vision converter with an efficient self-attention mechanism (DS-ViT-ESA) which can predict the stream.
