As the core component of electric vehicles (EVs), the performance of electric motors directly affects the economy and safety of EVs. Manufacturing tolerances will cause the actual performance parameters of the motor to deviate from the expected value, resulting in a reduction in motor service life. This paper presents a reliability-based design opt...

Battery Thermal Management System (BTMS) is crucial to maintain peak temperature and temperature difference of lithium-ion battery pack in appropriate range, thus ensuring best performance, extended cycle life and safety. Liquid cooling BTMS is extensively researched for prismatic cells, but only a few studies are present on application of liquid c...

To avoid severe resource waste and environmental pollution problems, research on the retirement of power lithium-ion batteries (LIBs) for electric vehicles (EVs) has attracted significant attention. Echelon utilization is one of the most prevailing strategies to solve the problems of reusing retired LIBs. In this paper, we present a clustering and...

Electric vehicles (EVs) have been substantially favored by consumers in recent years. However, long charging time, high battery purchase costs (BPC), and large charging load limit the development of EVs. The battery swapping scenario could solve the above problems well. This paper presents a battery centralized scheduling strategy (BCSS) in the bat...

The moving components and servo control systems of computer numerical control (CNC) machine tools spent a substantial energy but received less attention regarding energy saving. This article presents a novel energy saving methodology of feed system using a data-model hybrid driven design optimization approach for the integrated design of moving com...

Lithium-ion batteries are currently the primary source of power for electric vehicles (EVs), but the batteries are sensitive to temperature changes. Excessively high or low temperatures will affect the batteries performance, causing thermal runaway and safety accidents. The battery thermal management system (BTMS) can maintain the batteries within...

To solve a series of thermal runaway problems caused by temperature and the cost problem caused by the excessive volume of the battery thermal management system (BTMS), this paper presents a novel air cooling BTMS which reduces the temperature and volume. In this study, we install the spoilers in the battery gap spacing, which can effectively impro...

Electric vehicles (EVs) have been widely cherished by consumers in recent years. However, as the number of EVs continues to increase, the number of retired power batteries will also increase, especially retired power lithium-ion batteries (LIBs), which will cause serious energy waste. To reuse sufficiently retired power LIBs, we studied the remaini...
