Thermoelectric is a phenomenon of the temperature difference conversion into electrical energy or vice versa. The phenomenon has been developed into a module so that it can be used as a power generator or as a cooling/heating device. The use of thermoelectric can be further expanded as a system for generating small electrical energy and as a component for compact cooling and heating. If a unidirectional voltage is applied to the thermoelectric module, a temperature difference occurs between the two sides of the module. The cold side can be used as a cooler and the hot side can be used as a heater. Thermoelectric refrigeration technology has been applied in various applications such as beverage coolers and electronic coolers. However, the application of this technology in the vehicle still needs attention because it has good potential. Reviews relating to the application of thermoelectric cooling in vehicles are still not widely discussed, especially in terms of vehicles such as the performance of electric motors and braking. So, in this study, the use of thermoelectric as coolants in large components such as cooling in electric vehicles and braking components are discussed. Basic knowledge of the history, characteristics, performance of thermoelectric are also covered. Studies that had been carried out in several reported topics prove the potential and reliability of thermoelectric.

Electric motorcycle is one of the vehicles that can operate using alternative fuels, namely with electrical energy. Travel between cities over great distances, of course this results in a high risk of accidents. Additional features are needed that can warn and stop the electric motorcycle before crashing into other vehicles in front of it. Cruise Control is an automatic technology that is embedded in the automotive system to maintain a constant speed. Prototype refers to the physical and digital representation of pre-production models. This research focuses on applying ultrasonic sensors as distance detectors for the prototype adaptive cruise control system which will be installed as an additional feature on electric motorcycles. The method used in this research starts from simulating a series of systems on Proteus 7.9 software, then designing electrical and software devices on prototyping, and testing. The results obtained by adaptive cruise control mode by testing the variation of distance to PWM duty cycle changes in the simulation compared to prototyping, found an error of ± 1.53%, this shows the prototype Adaptive Cruise Control can work well.
