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.

“…Similarly, Zhang et al [16] conducted a comparative study elucidating the performance advantages of LiFePO4 batteries in terms of cycle life and energy density, affirming their potential for durable and long-lasting energy storage systems. In tandem with investigations into LiFePO4 batteries, research on battery management systems (BMS) is integral to optimizing their performance [17]. BMS is pivotal in monitoring, controlling, and safeguarding battery systems.…”

For tourism-based electric shuttles, high-energy batteries are crucial. A 200 Ah Lithium Iron Phosphate (LiFePO4) battery pack has been designed yet lacks performance evaluation. We conducted performance tests based on ISO 12405-4:2018. The battery comprises 24 cells connected in series, resulting in a 72 V output voltage. Under controlled conditions at 23°C, the test assessed charging and discharging at defined C-rates. The study assessed the resistance, capacity, and efficiency. We also monitored heat distribution in the battery system during test to detect abnormalities. The results revealed that the maximum attainable battery charge rate was C/3. Under this rate, the discharge capacity reached 160 Ah, and the battery temperature rose to just below 36.2°C. On the other hand, charging the battery at C/6 yielded 191.5 Ah, which increased the battery temperature to 31°C. Thus, the energy round-trip efficiency was measured at 86.5%. However, charging the battery at C/3 led to the Battery Management System (BMS) overheating, indicated by the casing temperature exceeding 67 °C. The overheating caused severe damage to the BMS charging component and triggered an automatic cut-off. The higher total battery resistance during charging was identified as the root cause of the issue, emphasizing the need for future research to focus on enhancing the BMS for faster and more efficient charging, improving the service reliability of the electric shuttle.

This paper presents a modelling of a high-frequency full bridge inverter for wireless power transmission (WPT) in Electric Vehicle (EV) charging applications. The inverter is designated at an operating frequency as high as 13.56 MHz in line with regulations for the industrial, scientific, and medical radio band (ISM band). Since the power is transferred wirelessly from the source to the EV, a coupling capacitive was used as a transmitter and receiver of the system. In this paper, the inverter model was simulated and analysed using LTSpice software. Different load changes and power are injected into the system. Furthermore, in order to obtain a robust system, the switching frequency of 13.56 MHz is used with some Dead Time (DT). The system already uses GaN MOSFETs for reliability and performance at high frequencies, in addition to LC impedance matching. The result is that by operating at a resonant frequency of 13.56 MHz with a resistive load of 50, it is obtained with a power of 2.3 kW that has been successfully transmitted with an efficiency of 89%.
