“…Internal combustion engines waste through the tailpipe about the same amount of thermal power they produce mechanically, around 35-40% of the fuel energy supplied, even when operating at top efficiency [1][2][3][4]. It is therefore advantageous to recover a portion of this wasted energy by converting it into electricity [5]. This electric recovery will be especially useful in the case of vehicles having a high degree of electrification, synergistically increasing the efficiency potential.…”

Thermoelectric generators (TEGs) have become a promising technology for vehicle exhaust heat recovery. In this paper, a novel prototype with reduced thermal inertia, low size and capable to withstand the exhaust highest temperatures has been proposed. A small-scale prototype has been built and tested for further study. Results of experiment show the reasonability for exhaust heat recovery. The prototype can generate a maximum power output of about 111 W when operating at exhaust temperatures of 700 ºC. The vehicle speed is a significant factor affecting the TEG performance for waste heat recovery. It can be found that the higher the vehicle speed is, the better the performance of the ATEG is. Also the temperature of the cooling system strongly affects the ATEG performance. Higher water cooling temperatures reduce temperature difference between hot and cold side of TEGs and cause a reduction on ATEG efficiency.

The electric turbocharger is a promising solution for engine downsizing. It provides great potential for vehicle fuel efficiency improvement. The electric turbocharger makes engines run as hybrid systems so critical challenges are raised in energy management and control. This paper proposes a real-time energy management strategy based on updating and tracking of the optimal exhaust pressure setpoint. Starting from the engine characterisation, the impacts of the electric turbocharger on engine response and exhaust emissions are analysed. A multivariable explicit model predictive controller is designed to regulate the key variables in the engine air system, while the optimal setpoints of those variables are generated by a high level controller. The two-level controller works in a highly efficient way to fulfill the optimal energy management. This strategy has been validated in physical simulations and experimental testing. Excellent tracking performance and sustainable energy management demonstrate the effectiveness of the proposed method.

Approximately 40% of the energy in traditional cars is discharged into the air through exhaust gas, causing a lot of waste of thermal energy, leading to huge economic losses. 1-3 Thermoelectric generators (TEGs) are the devices that can convert thermal energy into electrical energy, which can effectively achieve energy recovery. 4,5 Usually, the recovered electric energy is stored through a battery pack and is supplied to the vehicle-mounted electrical equipment. 6 The battery management system, as the core of battery monitoring, is widely used in electric vehicles. In software design, a reasonable algorithm is used to achieve battery state estimation and energy balance, which have a very important impact on vehicle safety. 7-12 But the system hardware structure design is also important, because the temperature of the battery pack rises during charging and discharging, the temperature between different batteries will cause the temperature in the battery pack to be inconsistent, and ultimately affect the life of the power battery. 13-15
