Abstract: The hybrid electric vehicle (HEV) has the potential of sufficing drive needs with better fuel efficiency. The complex nature of hybrid vehicle provides multiple opportunities for obtaining better fuel efficiency. The mathematical modeling is a necessity for understanding the behavior of HEV. The fuel efficiency is obtained through various means including the design of energy management system, component sizing, emission control, and other methods. In the present paper, a mathematical model of HEV is presented … Show more

The vehicles equipped with electromechanical transmission due to the development of traction electric drive, as well as on-board electric energy storage became very prospective. However, at the stage of such vehicles design the difficulties associated with evaluating the energy efficiency of the developed vehicles, in particular, with the evaluation of the efficiency of traction electric vehicles arise. In this work, the authors propose a method for evaluating the efficiency of traction electric motors of newly developed electromechanical transmissions of transport vehicles, based on the construction of an empirical dependence approximating statistical data on the characteristics of existing electric motors. The data on electric motors from a number of manufacturers used in vehicle transmissions was studied for approximation. The article discusses the application of the developed method to design an algorithm for controlling the transmission of a wheeled vehicle, aimed at increasing its energy efficiency. The efficiency of the algorithm is confirmed by simulation of the dynamics of the vehicle, the initial data for the simulation were obtained during the traction-dynamic calculation. The developed simulation model together with the method of evaluating the efficiency of the electric motor made it possible to carry out a comparative assessment of the developed gearshift control algorithm and the gearshift approach, which does not take into account the dependence of the energy losses of the electric machine on the operating mode in cases of urban and mixed driving cycles. As criteria for assessing the effectiveness of the application of the developed law of control of an electromechanical transmission, the amount of energy spent on movement along a given cycle and the number of gear shifts on the route were used. The obtained results confirm the effectiveness of using the developed algorithm in the conditions of vehicle movement in an urban environment.

Decentralized electrical power systems, driven by variable renewable energy sources such as solar PV and wind, have the potential to provide accessible and sustainable energy, contributing to the realization of a zero-carbon transition. However, these sources are susceptible to extreme weather conditions, presenting a challenge to the reliability of the power system. With abundant resources and a significant rural population lacking access to electricity, Africa has emerged as a key area for research on variable renewable energy-based electricity generation. Despite this focus, there remains a substantial gap in understanding at regional-scale the potential and variability of solar and wind power across various time scales, as well asthe impact of available resource synergy. Thisstudy aims to bridge this knowledge gap by conducting comprehensive simulations of hybrid wind and solar energy systems, both on-grid and off-grid, across 20 geographically diverse locations in Kenya. Using high-resolution hourly time step data, we examine the effect of resource complementarity on system reliability at varying time scales: daily, monthly and annually. The study findings shows the available VRE resource exhibit moderate tendency for complementarity, and optimizing their deployment can reduce hourly variability by 20%, significantly enhancing supply reliability, especially in the northern and eastern regions.
