Journal of Electronic Materials, 2019

Meeting the increasing global demand for energy coupled with the depletion of fossil fuel sources has created breakthroughs in research on waste heat energy harvesting devices. By utilizing waste heat, energy consumption does not grow and is efficiently used instead. Harvesting energy from automobiles has promising outcomes for the application of thermoelectric generators (TEGs). Heavy duty diesel engines, pickup trucks, sport bikes and model airplanes are involved in research attempting to do away with heavy batteries or alternators. For this study, a single cylinder, 100 cc Honda EX5 Dream, which is also known as 'Kapcai', was used to study the viability of installing TEGs for waste heat recovery in underbone of the motorcycle chassis. The natural convection passive cooling system of fin was used to dissipate heat for cold side of the TEGs to maintain temperature difference across TEGs of the motorcycle waste heat recovery system. Two currently commercially available TEG modules were used and were connected in series and parallel in order to obtain output power. Results for a single module of each of the two TEGs testing recorded a temperature gradient of 57.5°C and 62.7°C with open circuit voltage of 1.677 V and 1.704 V, respectively. The highest temperature difference and output voltage were recorded at 73.2°C and 4.2 V in series arrangement for both the TEGs. In the same arrangement, the highest power output obtained was 551.0 mW. The outcomes from this field testing shows the applicability of waste heat recovery from the underbone chassis of a typical motorcycle in charging small portable devices such as smartphones or power banks for the rider of motorbike.

One of the excess energies in the environment is motorcycle exhaust gas. Motorcycles with internal combustion engines produce energy waste where around 40% of the fuel energy is wasted in the form of heat energy through the exhaust to the environment. Various research studies to utilize the heat of motorcycle exhaust have been conducted, but the electric voltage generated is still below 5V. Therefore, it is not enough to be used as a power source for electronic devices using Universal Serial Bus (USB). This study aims to design an energy harvesting system using two modules of TEG TE-MOD-10W4V-40 that are organized in series and mounted on a motorcycle exhaust. The design of the device includes the construction of the heat exchanger, the boost converter circuit, and the charger box. The test results show that the maximum electrical voltage is successfully generated in a no-load condition of 4.2V with a temperature difference of 57°C. The design of the device is able to charge electronic devices such as speakers, smartphones, and tablets with an output voltage of 5.2V. The time needed since the motorcycle engine started to reach a constant voltage was 3 minutes.

In most vehicles with a combustion engine, about 65% of the remaining combustion energy dissipating as heat. Heat is a form of energy release from the combustion process in the combustion chamber channeled through a motorized vehicle's exhaust. The exhaust heat has the potential to be reused as a source of heat energy that can be transformed into electrical energy using a thermoelectric generator (TEG) attached to a motorized vehicle exhaust system. The application of TEG in motorcycle exhaust is an effort to increase the fuel efficiency of motor vehicles. This research aims to create and develop prototypes that apply TEG to motorcycle exhausts, convert motorcycle exhaust heat into electrical energy, and make prototype designs for cell phone chargers. Several steps have been conducted, including the design process with Autodesk Fusion 360 Student Edition application, while prototyping is done by manually assembling all the components used. The measuring instruments used during the prototype testing are the k-type thermocouple and DC voltage sensor connected to the data logger and laptop. The engine speed at the time of testing was 4000 RPM. In the test using a heat pipe, it was obtained ∆T 115°C on the cold side of TEG at a voltage of 4.47 V when the motorbike was stopped or idle, which was relatively better than the TEG test using a heatsink as a cooling system.

The main power source of motor vehicle is combustion engines which use fossil fuels (diesel, gasoline, pertamax etc.) as fuel. The total heat supplied to the engine in the form of fuel, 30-40% of fuel is converted into mechanical work, heat remaining is released through the exhaust pipe and the engine cooling system. The unused heat source in motor vehicles could potentially be used to generate electricity as a supplier of electricity needs in a vehicle. The technology used to convert the heat energy into electrical energy known as the thermoelectric generator, which uses the Seebeck theory as the basis of the principle works. This study uses a cylinder with a heating element inside (heater) as a heat source such as the exhaust pipes designed in a motor vehicle. Cylinder temperature is simulated as the temperature of the exhaust pipes of motor vehicles by varying the input voltage supplied to the heater (150V, 175V, 200V and 225V). This study also uses sub-sonic wind tunnel as a sou...

Conventional vehicles employ an internal combustion engine as its power house. The efficiency of the engine is 30-35%, thus 65-70% of the calorific energy is lost as residual exhaust, friction and various mechanical reduction through the power-train. The bulk of this loss is in the form of residual exhaust and heat. This energy lost in the form of heat can be extracted from certain regions in the engine which provide a significant temperature gradient. This paper proposes a conceptualized mechanism using thermoelectric generators (TEGs) that employs the seebeck effect to convert temperature gradient across two continuous surfaces to electrical energy. We propose to install an array of such highly efficient TEGs in the interface of a turbo charger to capitalize on the thermal gradient offered across its two housings. The installed TEG modules readily transduce the heat energy to electric energy, about 6000 watts of energy can be converted. The electrical energy thus developed can be ...

The purpose of the project is to build a TEG(Thermo Electric Generator) kit which can charge the mobile phone using the waste heat from motorcycle exhaust. Till now in India there is no any bike available in which provision for mobile phone charging is available with the help of waste heat. our device works on the principle of Seeback effect. According to seeback effect when one side of the TEG plate is hot and the other is cold, the temperature difference results in the conversion of voltage difference. This project focuses on using the waste heat of motorcycle exhasust and converting the heat energy into electrical energy with the help of TEG(Thermo Electric Generator). The kit comprises of TEG modules which are made up of semiconductors. Bismuth telluride(Bi2Te3), lead telluride(PbTe), and silicon germanium(SiGe) are commonly used semiconductors. This kit takes the heat energy from the exhaust pipe of motorcycle and the cooling is done by the free convection with the help of fin attached on the other side of the TEG module. This temperature difference is converted into voltage difference by TEG module. This voltage difference is further regulated by voltage regulator and finally can be used for mobile phone charging. It is best option for mobile phone charging as it uses the waste heat and also not affect the environment as it is not causing any type of pollution. This project is overall cost saving and environment friendly.

Thermoelectric generators (TEG) in internal combustion engine (ICE) powered vehicles has been focused as a green energy technology to improve fuel economy and consequently to reduce emission of the greenhouse gas of í µí° ¶í µí±‚ 2 .Only small amount of the fuel combustion energy is converted to mechanical energy, while about a large amount is wasted through exhaust gas.
