Summary: This paper compares the performance of a thermoelectric generator prototype applied in conventional vehicles and extended-range electric vehicles through simulation and experimental methods. The effects of power management strategies, driving cycles, and auxiliary power on the fuel economy improvement are analyzed. The results show that in urban driving cycles, the thermoelectric generator applied in extended-range electric vehicles using the power follower control strategy has better fuel economy compared to integration into conventional vehicles. However, in highway driving cycles, the fuel saving effect of the thermoelectric generator integrated in conventional vehicles is better. It is also shown that the power follower control strategy is more suitable for the integration of thermoelectric generators in extended-range electric vehicles.

Summary: This study proposes an energy consumption model for long-range autonomous underwater vehicles (LRAUVs) considering seawater density variation and drive loss, and establishes the functional relationship between shape parameters, sailing parameters, and sailing efficiency using the response surface method. The optimization results suggest that AUV mode shows higher efficiency in shallow sea, while glider mode is more suitable for deep-sea operation. Based on the proposed method, a Petrel LRAUV with optimized shape and sailing efficiency is developed, which can also serve as a reference for the preliminary design of other LRAUVs.

Summary: Progress is being made in decarbonization of road transport to reduce greenhouse gas emissions and their negative impacts. Hydrogen-electric hybridization appears to be a promising option for reducing emissions by providing vehicles with sufficient range and competitive performance. The development of efficient energy management systems is crucial in extending vehicle range. This study proposes two energy management systems for hydrogen hybrid vehicles, namely a Plug-in Hybrid Electric Vehicle (PHEV) and a Range-Extended Fuel Cell Hybrid Vehicle (FC-EREV). These systems utilize single and multi-level approaches to distribute current demand between the fuel cell and battery based on the amount of hydrogen in the tank. The parameters of the energy management systems were optimized using a particle swarm optimization algorithm, resulting in up to 9% and 12% range improvements for the single and multi-level approaches, respectively, compared to previous works.

Summary: The paper proposes an H-shaped coupler energy harvester (HC-EH) for the onboard power supply of freight trailer safety monitoring sensors in heavy railways. The HC-EH consists of three modules: vibration input, motion conversion, and energy conversion. The H-type structure of the HC-EH solves the damage caused by the impact force between couplings on heavy railways. A generator converts kinetic energy into electricity stored in supercapacitors and provides power for the railway onboard monitoring sensor network. The practical applications of the proposed HC-EH in the Datong-Qinhuangdao Railway are studied.

Summary: This study provides an in-depth summary of rotary, hydraulic, and linear electromagnetic regenerative shock absorbers (RSA) and discusses their applications and technical challenges. It reveals that achieving maximum energy harvesting and ride comfort simultaneously in RSAs is difficult, and hydraulic RSAs have lower energy harvesting efficiency compared to rotary and linear RSAs, making them unsuitable for lightweight vehicles. The bibliometric analysis highlights China as the most productive country in terms of publications related to energy harvesting from RSAs.
