Abstract

The cost incurred in the EV Charging is currently only from the energy consumed consideration. While there is extensive research on the impact of EV charging on grid infrastructure and operation, few studies quantify these effects in terms of explicit 'damage costs'. However, besides energy problems, the analysis of the environmental impact of EVs has not been quantified monetarily. This paper aimed to investigate the damage cost (DC) of EVs in comparison with Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs) based on Indonesia Java Bali's grid conditions. Using the existing data in Indonesia, the characterisation parameter were determined using cradle-to-gate life cycle analysis (LCA) and ReCiPe 2016 then converting the endpoint indicators impacts to DC using a monetary weight factor (MWF) of those two EVs. Cradle to gate LCA is a method for evaluating the environmental impact of battery from the extraction of raw material to the factory gate and ReCiPe 2016 is a widely used of LCA method, which converts emission and resources extraction into certain indicators. Results show that DC for a 20 kWh BEV = 0.12 ± 0.01 USD/kWh compared to an 8 kWh PHEV = 0.08 ± 0.005 USD/kWh. Therefore, the DC of an extra 0.02 USD/kWh for BEVs and 0.015 USD/kWh for PHEVs should be considered in formulating the EV charging tariff.

Abstract

The growing demand for compact, efficient, and eco friendly cooling solutions has driven research into integrating thermoelectric coolers (TECs) with solar photovoltaic (PV) systems, where solar irradiance variability impacts cooling efficacy and energy efficiency. This challenge is addressed using DC-DC Buck-Boost converters whose performance is heavily influenced by control strategies such as Proportional Integral Derivative (PID) controllers employing tuning approaches that balance performance and prioritize disturbance rejection. This study investigates the implementation and performance of a DC-DC buck-boost converter in a solar photovoltaic and thermoelectric cooling (PV-TEC) system. Simulation-based analysis compared tuning methods for their ability to maintain thermal stability, reduce electrical input fluctuations, and enhance the TEC's Coefficient of Performance (COP). Results show that the PID controller significantly improves responsiveness and energy efficiency in dynamic solar conditions, achieving a 23% reduction in power consumption and a 36% increase in COP, highlighting the importance of adaptive control strategies.

Abstract

The temperature-induced efficiency loss of 0.4% to 0.5% for every °C above 25 °C alongside the inherent variability in solar irradiance, poses a critical challenge to the efficiency and stability of Photovoltaic (PV) modules. This study addresses this limitation by developing and analyzing an Integrated Photovoltaic Thermal-Thermoelectric Cooler (PV/T–TEC) system designed for robust thermal management and enhanced energy yield. The proposed system utilizes a synergistic hybrid cooling mechanism: a passive PV/T air collector for bulk heat dissipation from the PV panel's rear surface, coupled with an active Thermoelectric Cooler (TEC) for precise temperature stabilization. The electrical energy flow is managed by a DC–DC Boost Converter employing a PID controller, with a focus on input disturbance rejection, ensuring the TEC operates at an optimal, stable power point.Simulation and performance analysis demonstrate the significant advantages of this hybridized approach. The PV/T air collector was confirmed as the primary thermal component, achieving a peak heat dissipation QEmit approximately 7.5 times greater than the TEC-only configuration. This strategic pre-cooling successfully stabilizes the TEC's hot-side temperature, enabling the TEC to operate with a low operational temperature differential ∆T and resulting in an exceptionally high calculated Effective System Coefficient of Performance COP peaking at 14.5. The system maintains a stable operating point during peak solar radiation, maximizing the Net Electrical Power Gain. In conclusion, the integration of passive PV/T cooling, active TEC cooling, and a PID-enabled DC–DC Boost Converter provides an exceptionally efficient and stable solution for PV thermal management. The research strongly supports the efficacy of this hybrid system for significantly improving the overall energy efficiency and sustainability of solar energy applications.
