Abstract

The central objectives of this study are to locate existing research on renewable energy, examine the energy policy of Tanzania, assess bibliometric factors, determine the direction of the current research, and comprehend unexplored research topics. This exploration focuses on a bibliometric-based study using computer-assisted software tools known as VOS viewer and RStudio in analyzing the Scopus data retrieved package for the key phrase of "Renewable energy" in the article titles published from 2002 to 2022. A total of 661 publications (which is only 0.45% and 6.3% of the global and continental publications from Africa respectively) were analysed after refining using different bibliometric criteria like study site, type of document, publication stage, language used in the document, and publication time interval. The results shows that Energy fuels, engineering, technology, environmental sciences, ecology, and business economics are the most frequently studied fields. Also, from a total of 661 publications, only 32 documents were published from Tanzania for 20 years from 2022 which is less than 2 publication/year. This study concludes that there is a notable lack of research output from Tanzania in this critical field. This gap underscores the need for greater investment in renewable energy research and development within the country, as well as targeted efforts to build research capacity and foster collaboration among academia, government, and industry stakeholders.

Abstract

The extraordinary growth in means of transportation, especially vehicles with internal combustion engines, has made state laws and regulations increasingly stringent. Regulations regarding energy consumption used for passenger and personal mobility and the emissions produced in order to reduce pollution. A hybrid vehicle combines two energies produced from various sources such as an ICE and an electric motor to become a hybrid electric vehicle (HEV). This research discusses hybrid electric vehicles on 2-wheeled vehicles which can be used as a solution that can be developed further before pure electric vehicles (EV) replace motorized vehicles (ICE). This research was done experimentally, by carrying out tests on a dynamometer and on the road testing. The main material used in this research was a Honda PCX 150 vehicle. The results of the test on the dynamometer showed that the performance of the internal combustion engine (ICE) had a torque of 11.12 Nm and a power of 8.20 kW at 7000 rpm. Testing the electric motor (EV), obtained torque results of 11.7 Nm and 2.33 kW power. The road test results for internal combustion engine consumption to consume 1 liter of fuel, capable of covering a distance of 54.55 km. Electricity consumption from 100% to 0% SOC can cover a distance of 46.31 km. Hybrid consumption 1 liter of fuel and battery full 100% capable of covering a distance 57.79 km, with battery condition reduced 16%.

Abstract

Making efficient batteries is important nowadays. One potential problem that can hinder this is the thermal runaway that occurs in battery cells. There are various causes of thermal runaway, one of the most common is an increase in temperature that exceeds the optimal allowable limit. Additional cooling will be required in vehicles that use batteries. Battery Thermal Management System (BTMS) with mini-channel cooling plate is one of the methods often used to maintain battery performance. In this study, the performance of Lithium-ion batteries is affected by fluid flow velocity. The experimental process was carried out by charging and discharging with a C-rate of 1C. Cooling is done with ethylene glycol fluid with fluid velocity variations of 0.21 L/min; 0.42 L/min and 0.63 L/min. The results show that fluid flow velocity affects the final battery temperature and battery performance. The optimal fluid velocity is shown at 4.2 L/min. At this speed it can reduce the battery temperature by 6.7°C.
