“…ECB is an electromagnetic brake that uses the principle of eddy current, which is produced by the induction when the rotor rotates due to the magnetic field produced by the stator 65,66) . With this Eddy Current existence not only can be used for ECB but also supplying energy to the thermoelectric as cooler.…”

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 vehicles are better for the environment. Lithium-ion (Li-ion) battery cells can be used as energy storage. Some uses of the battery are not only used as a power supply for electric motors but are also used in supporting systems such as an additional braking system using Eddy Current Brake (ECB). In general, ECB requires a large current when starting the braking process. At this early stage, the heat will be generated relatively high. During operation, heat is generated, and it will burden the battery's performance. Thus, the heat generated needs to be released into the environment. Careless heat management can have multiple effects, such as fire and, in the worst case, explosion. Battery Thermal Management System (BTMS) needs to be implemented in electric vehicles. There are several methods of thermal management, such as air-cooled and liquid-cooled. The results show that liquid-cooled BTMS is superior in uniform but more complex temperature distribution, and liquid leakage may occur. In comparison, air-cooled BTMS has the advantage of a more accessible system, but the temperature distribution between batteries is not good. Air Cooler can maintain the ideal battery temperature between 20-40 °C.

“…This principle uses the generation of primary magnetic induction formed in conductor materials. In general, magnetic materials that have high permeability can produce high magnetic flux [3][4][5][6]. In other words, the eddy current phenomenon can be more effectively generated with an electric current in materials with low electrical resistance.…”

The eddy current brake (ECB) is a braking technology that continues to be developed. The use of the ECB has excellent potential to be applied to vehicles. Various studies have proposed the design, characteristics, and advantages of each. However, further analysis is needed to assess the performance of the ECB and what factors affect the performance. However, no studies have been found that discuss eddy current brakes using bibliometric analysis. Bibliometric analysis is a method used for mapping and knowledge of existing gaps in a particular topic. This article aims to provide a complete discussion with bibliometric statistical methods that have never been presented before in the field of eddy current brakes, especially the phenomenon of heat generation. In addition, the prediction of research gaps in this field can be identified as the initial results of further research. The analysis was carried out using VOSviewer and Biblioshiny integrated through the RStudio tool. The data are obtained through the Scopus database, which is then exported in CSV form. Obtaining the data depends on the keywords used. In this case, the obtained document is filtered with the features provided by Scopus. From the analysis conducted, it was found that the topic related to heat in eddy current brakes is still a recent discussion. Discussions on the heat increase in the ECB are still limited and require mapping and analysis of what parts still need development. The phenomenon of heat generation is one novelty that allows it to be researched. One example from the scientific data obtained is that there are 207 documents in the form of articles and conference papers with a total of 533 authors.
